These morbidities may pose a 9 threat to fetal immunological development through associated metabolic dysfunction and 10 Confidential: For Review Only 11 and, as such, may partly explain the concurrent rise of pediatric allergic disease. We will examine the 12 13 effect of excess maternal pre-pregnancy weight and gestational weight gain during pregnancy on the 14 incidence of allergic diseases among offspring in Canada’s most populous province. 15 16 17 Methods and analysis 18 19 We will conduct a retrospective, population-based cohort study of all singleton live births to residents of 20 21 Ontario, Canada in 2012–13 and 2013–14. The study population will be defined using maternal-newborn 22 records from the provincial birth registry, which captures information on maternal pre-pregnancy weight 23 24 and gestational weight gain. The cohort will be linked with provincial health administrative databases, 25 allowing for follow-up of neonates through early childhood until 2019 (5–7 years of age). Allergic disease 26 27 development (asthma, rhinitis, atopic , and ) will be ascertained using diagnostic 28 codes from healthcare encounters. Potential confounders have been identified a priori through a directed 29 30 acyclic graph. Cox proportional-hazards regression models will be employed to assess the associations http://bmjpaedsopen.bmj.com/ 31 32 between excess maternal pre-pregnancy weight, gestational weight gain, and incident pediatric allergic 33 disease.

Downloaded from MATERNAL WEIGHT AND PEDIATRIC ALLERGIC DISEASE 1 2 3 INTRODUCTION 4 5 In 1997, the World Health Organization declared obesity a global epidemic.1 Since then, excess maternal 6 pre-pregnancy weight (body mass index [BMI]≥25kg/m2) and gestational weight gain (GWG) have 7 8 become the most common morbidities in pregnancy.2,3 A recent analysis of perinatal registry data from 9 four Canadian provinces found that 35–55% of singleton live births are born to overweight or obese 10 Confidential: For Review Only 11 mothers, while 50–66% are born to mothers who exceed GWG recommendations.3 These morbidities are 12 13 associated with metabolic dysfunction and inflammation, which pose a threat to the homeostasis of the 14 fetal compartment and could result in impaired fetal immunological development and increased chronic 15 16 disease susceptibility in later life.2 Therefore, the rise of excess weight and GWG during pregnancy may 17 partially explain the concurrent rise in pediatric allergic disease,4 which is now one of the most common 18 19 and earliest-onset morbidities in childhood.5 One 2016 study conducted in Ontario found that 44% of 20 21 toddlers suffered from food , environmental allergies (wheezing, asthma, eczema, or rhinitis), 22 atopy, or a combination thereof.6 Though one cross-sectional and several longitudinal studies have 23 24 assessed the early-life programming of allergic diseases by maternal weight or GWG, they have been 25 limited by small sample sizes (<1000)7,8 and self-reported measures of the exposure or outcome,7–19 which 26 27 have reduced their generalizability and validity. Further, most have focussed on asthma alone,7–14 none 28 have examined anaphylaxis, and none have calculated risk by the length of follow-up time, opting instead 29 30 8,13,17 7,9–12,14–16,18 for aggregate rates (log-linear model), odds (logistic model), or prevalence ratios (log- http://bmjpaedsopen.bmj.com/ 31 19 32 binomial model). As well, none of these studies have been undertaken in Canada, which has a unique 33 multicultural population. This proposed research will attempt to address these evidence gaps by carrying 34 35 out a large population-based study in Canada’s most populous province. 36 37 38 Aims 39 40 We will assess the impact of excess maternal pre-pregnancy weight (overweight and obesity) and GWG on September 25, 2021 by guest. Protected copyright. 41 on the incidence of childhood allergic diseases (asthma, rhinitis, , and anaphylaxis). 42 43 Based on previous literature, we hypothesize that maternal overweight, obesity, and excess GWG will all 44 increase the risk of allergic diseases in offspring, with GWG incurring the greatest risk. This work may 45 46 help inform public health initiatives for high-risk groups and increase early prevention, identification, and 47 treatment of early childhood morbidity. 48 49 50 51 METHODS AND ANALYSIS 52 Design and Setting 53 54 We will conduct a population-based retrospective cohort study of all singleton live births to residents of 55 Ontario, Canada between 1 April 2012 and 31 March 2014, with follow-up of children to 31 March 2019 56 57 58 59 4 60 https://mc.manuscriptcentral.com/bmjpo BMJ Paediatrics Open Page 6 of 91 bmjpo: first published as 10.1136/bmjpo-2020-000893 on 5 January 2021. Downloaded from MATERNAL WEIGHT AND PEDIATRIC ALLERGIC DISEASE 1 2 3 (Figure 1). The study will be conducted using multiple linked province-wide health databases within the 4 5 secure network environment of ICES (https://www.ices.on.ca/). This protocol was developed following 6 the REporting of studies Conducted using Observational Routinely-collected health Data (RECORD) 7 8 guidelines.20 9 10 Confidential: For Review Only 11 Data Sources and Population 12 13 The birth cohort will be defined using maternal-newborn records from the provincial birth registry, the 14 Better Outcomes Registry & Network (BORN) Information System (BIS). The BIS captures all hospital 15 16 births ≥500g or ≥20 weeks of gestation in Ontario, as well as detailed clinical and demographic 17 information about the birth and the mother. Deterministic and probabilistic methods have been used to 18 19 link the BIS database to health administrative databases at ICES, enabling follow-up of offspring health 20 21 outcomes into early childhood (5–7 years of age). All residents of Ontario are covered by publicly funded 22 universal healthcare and are eligible to access the services captured in the health administrative databases. 23 24 The health administrative databases at ICES to be used in this study include: the Canadian Institute for 25 Health Information (CIHI) Discharge Abstract Database (DAD); the CIHI National Ambulatory Care 26 27 Reporting System (NACRS); the Ontario Health Insurance Plan (OHIP) database; the Ontario Asthma 28 Surveillance Information System (ASTHMA); the Ontario Drug Benefit (ODB) database; the Ontario 29 30 portion of the federal Immigration, Refugees and Citizenship Canada (IRCC) Permanent Resident http://bmjpaedsopen.bmj.com/ 31 32 Database; and the Ontario Marginalization Index (ON-Marg). All data sources and reasons for use are 33 displayed in Figure 2. The study population will be restricted by sample exclusions (non-Ontario resident; 34 35 stillbirth; twin or higher-order multiple birth; mother’s age outside probable range [i.e., <12 years or >50 36 years]; and infant died on date of birth) and administrative exclusions (duplicate records in BORN; 37 38 invalid linkages and linkage warnings; invalid infant and mother identifiers; mothers without continuous 39 40 OHIP eligibility throughout pregnancy; and infants who did not have records of health care eligibility on September 25, 2021 by guest.

Figure 3 displays temporal aspects of the study design relating to eligibility, 42 43 variable measurement, and follow-up; this figure was previously proposed by Schneeweiss and 44 colleagues.21 45 46 47 Exposures 48 49 The primary exposures of interest will be maternal pre-pregnancy BMI and GWG. Ascertainment. Pre- 50 51 pregnancy BMI will be calculated by dividing pre-pregnancy weight (kg) by height (m), squared. For 52 approximately 70% of participants, data on maternal weight will be available from the first prenatal 53 54 screening visit at around 12 weeks of gestation (available from the Prenatal Screening Ontario [PSO] 55 encounter within the BIS database), where it is likely to have been objectively measured. From this, pre- 56 57 58 59 5 60 https://mc.manuscriptcentral.com/bmjpo Page 7 of 91 BMJ Paediatrics Open bmjpo: first published as 10.1136/bmjpo-2020-000893 on 5 January 2021. Downloaded from MATERNAL WEIGHT AND PEDIATRIC ALLERGIC DISEASE 1 2 3 pregnancy weight will be estimated by subtracting the typical first trimester weight gain.22 For subjects 4 5 with no record in the PSO database (due to no prenatal screening), maternal pre-pregnancy weight will be 6 captured from the Labour & Birth encounter within the BIS database, where the data may be based on 7 8 either self-report or objective measurement. GWG will be calculated by subtracting maternal pre- 9 pregnancy weight from weight recorded at delivery. Measures. Pre-pregnancy BMI will be classified 10 Confidential: For Review Only 11 according to World Health Organization categories: underweight (<18.5 kg/m2), normal weight (18.5– 12 2 2 2 1 13 24.9 kg/m ), overweight (25.0–29.9 kg/m ) or obese (≥30.0 kg/m ). The Institute of Medicine (IOM) 14 recommendations for weight gain during pregnancy suggest total weight gain for singleton 15 16 should not exceed 12.5–18 kg, 11.5–16 kg, 7–11.5 kg, or 5–9 kg based on pre-pregnancy BMI category, 17 respectively.23 However, these recommendations do not account for gestational length. To do so, we will 18 19 follow previously published methods24 to establish expected GWG based on IOM recommendations for 20 21 weight gain by trimester and pre-pregnancy BMI and calculate the ratio of actual to expected GWG. We 22 will then employ the recommended ratio ranges calculated by Guo and colleagues24 to classify GWG into 23 24 three categories: inadequate, adequate, or excess weight gain. These ratio ranges were determined by 25 dividing the lower and upper limits of the IOM GWG recommendations by the expected GWG within 26 27 each pre-pregnancy BMI category. 28 29 30 Outcomes http://bmjpaedsopen.bmj.com/ 31 32 Asthma, rhinitis, atopic dermatitis, and anaphylaxis will be examined separately during follow-up based 33 on International Classification of Diseases (ICD)-9 and ICD-10 diagnostic codes in health administrative 34 35 datasets (DAD, NACRS, and OHIP). ICD codes and algorithms can be found in Supplementary File A. 36 We will employ a time-to-first-event analysis for all outcomes, in which the follow-up period will begin 37 38 at birth and continue until either the outcome occurs, the infant dies or becomes ineligible to receive 39 40 healthcare services (with a 90 day grace period), or until the end of the study period, whichever comes on September 25, 2021 by guest. Protected copyright. 41 first. Follow-up time (person-days) will be calculated for each event separately. Asthma. Using a 42 43 validated algorithm, the ASTHMA database will identify infants with asthma diagnoses. The algorithm 44 requires ≥1 hospitalization and/or ≥2 ambulatory care visits for asthma within two years, where the 45 46 earliest claim is deemed the date of diagnosis.25 The algorithm was first validated among children in 2006 47 (ages 1–8; sensitivity: 91%, specificity: 83%),26 and was recently re-validated in 2019 among younger 48 49 children (ages 1–5; sensitivity: 81%, specificity: 90%).27 Since the accuracy of asthma diagnoses among 50 51 young infants is debated, records fulfilling the algorithm for asthma diagnosis before the age of 6 months 52 will be disregarded unless a further hospitalization or ambulatory care visit for asthma is detected after 12 53 54 months of age.28 Rhinitis and atopic dermatitis. Rhinitis and atopic dermatitis cases will be captured by 55 an algorithm from Hill and colleagues, which requires ≥2 care visits occurring ≥6 months apart and where 56 57 58 59 6 60 https://mc.manuscriptcentral.com/bmjpo BMJ Paediatrics Open Page 8 of 91 bmjpo: first published as 10.1136/bmjpo-2020-000893 on 5 January 2021.

These algorithms displayed positive predictive values of 100% and 4 5 90% based on chart review, respectively (no sensitivity or specificity measures were published).29 6 Anaphylaxis. We will employ criteria A and B from the algorithm by Walsh and colleagues30 to detect 7 8 anaphylaxis in inpatient, emergency department, and outpatient encounters using ICD codes for diagnoses 9 and symptoms. In a validation study, this algorithm performed better than those of previous studies, with 10 Confidential: For Review Only 11 a sensitivity of 91% and positive predictive value of 67%.30 Some modifications were made to the 12 13 algorithm for our study, including the removal of the three procedure/intervention codes which are not 14 available in our outpatient dataset and the inclusion of an ICD code for anaphylactic shock due to food 15 16 reaction due its high prevalence in childhood. 17 18 19 Covariates and Confounders 20 21 The following covariates and potential confounders will be examined: maternal characteristics (maternal 22 country of birth [for recent immigrants, otherwise Canada], maternal age at birth, maternal smoking, 23 24 parity, maternal asthma and other pre-existing medical conditions, and use of drugs, , or 25 during pregnancy); neighbourhood characteristics, using residential postal codes linked to 26 27 Census data (neighbourhood marginalization index and rural residence); and birth or infant characteristics 28 (mode of delivery, complications of pregnancy, season of birth, sex of infant, gestational age, birth 29 30 weight, and exclusive at time of hospital discharge). Causal assumptions are presented in a http://bmjpaedsopen.bmj.com/ 31 11,13 32 directed acyclic graph (DAG; Figure 4), adapted from two published DAGs and supplemented for our 33 study through a review of the literature. Before statistical analysis, 10 multiple imputation datasets will be 34 35 generated to deal with missing values. The results from the imputed datasets will be combined to produce 36 final estimates, following best practices.31 37 38 39 40 Statistical Analyses on September 25, 2021 by guest. Protected copyright. 41 Sample characteristics will be presented as frequencies and proportions for categorical variables and 42 43 means or medians for continuous variables (with measures of spread, such as standard deviation or inter- 44 quartile range), overall and stratified by exposure group to present potential confounding.32 Between 45 46 group-differences will be assessed by standardized differences, which denote differences in units of 47 standard deviation. Standardized differences greater than 10% indicate an imbalance between the 48 49 exposure groups.33 Crude incidence rates (per 100,000 person-days of follow-up) for each study outcome 50 51 will be calculated for each exposure group and graphically presented using cumulative incidence curves. 52 53 54 For the primary analyses, Cox proportional-hazards regression models will be employed to produce 55 hazard ratios (HR) with 95% confidence intervals (95% CI). Crude and adjusted analyses (utilizing 56 57 58 59 7 60 https://mc.manuscriptcentral.com/bmjpo Page 9 of 91 BMJ Paediatrics Open bmjpo: first published as 10.1136/bmjpo-2020-000893 on 5 January 2021.

Models will be 9 adjusted for maternal age, maternal birth country, maternal pre-pregnancy health conditions, maternal 10 Confidential: For Review Only 11 and substance use during pregnancy, neighbourhood characteristics, and parity—the minimal 12 13 sufficient adjustment set identified in the DAG (Figure 4). Cox models will account for repeated 14 pregnancies during the 2012–2014 period by adjusting the variance through generalized estimating 15 16 equation (GEE) methods.34 The following effect measure modifiers have been selected a priori: pre- 17 pregnancy BMI (when GWG is the exposure), GWG (when pre-pregnancy BMI is the exposure), and 18 19 infant sex. If estimates between strata are qualitatively different, we will introduce an interaction term or 20 35 21 report strata-specific estimates based on published guidelines. The proportional hazards assumption of 22 the Cox models will be assessed through Schoenfeld residual plots and Wald tests for interaction between 23 24 exposure status and time. All analyses will be conducted using SAS version 9.4 (SAS Institute, Cary, 25 NC). 26 27 28 Pre-planned Sensitivity Analyses 29 30 Assessment of Potential Selection Biases and Residual Confounding http://bmjpaedsopen.bmj.com/ 31 32 1. A complete case analysis will be conducted. 33 2. To understand the impact of exclusion criteria on selection bias, sociodemographic information of 34 35 response, complete-case, and imputed samples will be compared.32 36 3. To account for potential residual confounding by maternal propensity to access healthcare 37 38 services, we will assess typical maternal healthcare utilization through outpatient visits in the 39 40 OHIP database during a one-year look-back period before pregnancy and adjust for this in our on September 25, 2021 by guest.

Only mothers who were continuously eligible for OHIP during the look-back period will 42 43 be included. 44 45 46 Assessment of Potential Exposure Misclassification 47 4. To ensure that self-reported maternal weight does not bias our results, a subgroup analysis will be 48 49 undertaken among the subset of participants with pre-pregnancy weight recorded in the prenatal 50 encounter of the BIS database. 51 52 53 Assessment of Potential Outcome Misclassification 54 55 56 57 58 59 8 60 https://mc.manuscriptcentral.com/bmjpo BMJ Paediatrics Open Page 10 of 91 bmjpo: first published as 10.1136/bmjpo-2020-000893 on 5 January 2021. Downloaded from MATERNAL WEIGHT AND PEDIATRIC ALLERGIC DISEASE 1 2 3 5. Researchers from Denmark created36 and validated37 algorithms that employ hospital diagnoses 4 5 and dispensed prescription medications to identify cases of rhinitis (sensitivity: 84%, specificity: 6 82%) and atopic dermatitis (sensitivity: 74%, specificity: 73%) in childhood compared to parental 7 8 reports of physician diagnoses. In our study, data on prescription medications dispensed can only 9 be ascertained for the subset of participants who were covered by the provincial drug funding 10 Confidential: For Review Only 11 system (Ontario Drug Benefit, ODB). Residents of Ontario qualify for ODB if they are either ≥65 12 13 years old or are enrolled in one of the following provincial programs: home care and community 14 services, employment assistance, assistance for persons with disabilities, or assistance with 15 16 prescription-drug costs for those in financial need; starting on 1 January 2018, ODB was 17 extended to any resident of Ontario covered by OHIP+: Children and Youth Pharmacare (≤24 18 19 years old). We will run a sensitivity analysis using these derived algorithms for rhinitis and atopic 20 21 dermatitis in the subgroup of children whose families qualified for ODB (see Supplementary File 22 A for algorithms and codes). 23 24 6. We believe that the algorithms employed may result in non-differential outcome 25 misclassification, which usually produces bias towards the null or, in some circumstances, no 26 27 bias.38 A probabilistic bias analysis will be conducted to evaluate the influence of this 28 misclassification, following published methods.39 29 30 http://bmjpaedsopen.bmj.com/ 31 32 PATIENT AND PUBLIC INVOLVEMENT 33 Patients and the public were not involved in the development of the protocol. 34 35 36 ETHICS AND DISSEMINATION 37 38 Approval was obtained from the Research Ethics Board of the Children’s Hospital of Eastern Ontario 39 40 (protocol No 19/14PE) and the ICES Privacy Office (protocol No 2020 0901 237 000).

Study design and cohort structure. Adapted from Schneeweiss et al, 2019. Abbreviations: BMI, body-mass index; GWG, gestational 36 weight gain. Numbers in square brackets represent date ranges relative to the date of birth (day 0). 37 a For the purposes of illustrating the temporal relationship between maternal and infant study variables, the date of the LMP is shown as day -280 38 (i.e. 40 completed weeks of gestation). In the study, this will depend on the actual length of gestation. 39 b Sample exclusions include: non-Ontario resident; stillbirth; twin or higher-order multiple birth; mother’s age outside probable range (i.e. <12 years or >50 years); and infant died on date of birth. Administrative exclusions include: duplicate records in BORN; invalid linkages and linkage 40 warnings; invalid infant and mother identifiers; mothers without continuous OHIP eligibility throughout pregnancy; and infants who did not have 41 records of health care eligibility within 90 days of birth. c Pre-existing maternal conditions are ascertained on delivery record but reflect previous history. 42 d Only mothers who were continuously eligible to receive health care (OHIP) during the one-year period will be included. 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 bmjpo: first published as 10.1136/bmjpo-2020-000893 on 5 January 2021.

Downloaded from MATERNAL WEIGHT AND PEDIATRIC ALLERGIC DISEASE 1 2 3 ABSTRACT 4 5 Introduction 6 Over the last 20 years, excess maternal pre-pregnancy weight (overweight and obesity) and gestational 7 8 weight gain have become the most common morbidities in pregnancy. These morbidities may pose a 9 threat to fetal immunological development through associated metabolic dysfunction and inflammation 10 Confidential: For Review Only 11 and, as such, may partly explain the concurrent rise of pediatric allergic disease. We will examine the 12 13 effect of maternal pre-pregnancy weight and gestational weight gain during pregnancy on the incidence of 14 allergic diseases among offspring in Canada’s most populous province. 15 16 17 Methods and analysis 18 19 We will conduct a retrospective, population-based cohort study of all singleton live births to residents of 20 21 Ontario, Canada in 2012–13 and 2013–14. The study population will be defined using maternal-newborn 22 records from the provincial birth registry, which captures information on maternal pre-pregnancy weight 23 24 and gestational weight gain. The cohort will be linked with provincial health administrative databases, 25 allowing for follow-up of neonates through early childhood until 2019 (5–7 years of age). Allergic disease 26 27 development (asthma, rhinitis, atopic dermatitis, and anaphylaxis) will be ascertained using diagnostic 28 codes from healthcare encounters. Potential confounders have been identified a priori through a directed 29 30 acyclic graph. Cox proportional-hazards regression models will be employed to assess the associations http://bmjpaedsopen.bmj.com/ 31 32 between maternal pre-pregnancy weight, gestational weight gain, and incident pediatric allergic disease. 33 Several pre-planned sensitivity analyses will be conducted, including a probabilistic bias analysis of 34 35 outcome misclassification. 36 37 38 Ethics and dissemination 39 40 Ethics approval was obtained from the Research Ethics Board of the Children’s Hospital of Eastern on September 25, 2021 by guest.

Downloaded from MATERNAL WEIGHT AND PEDIATRIC ALLERGIC DISEASE 1 2 3 INTRODUCTION 4 5 In 1997, the World Health Organization declared obesity a global epidemic.1 Since then, excess maternal 6 pre-pregnancy weight (body mass index [BMI]≥25kg/m2) and gestational weight gain (GWG) have 7 8 become the most common morbidities in pregnancy.2,3 A recent analysis of perinatal registry data from 9 four Canadian provinces found that 35–55% of singleton live births are born to overweight or obese 10 Confidential: For Review Only 11 mothers, while 50–66% are born to mothers who exceed GWG recommendations.3 These morbidities are 12 13 associated with metabolic dysfunction and inflammation, which pose a threat to the homeostasis of the 14 fetal compartment and could result in impaired fetal immunological development and increased chronic 15 16 disease susceptibility in later life.2 Therefore, the rise of excess weight and GWG during pregnancy may 17 partially explain the concurrent rise in pediatric allergic disease,4 which is now one of the most common 18 19 and earliest-onset morbidities in childhood.5 One 2016 study conducted in Ontario found that 44% of 20 21 toddlers suffered from food allergies, environmental allergies (wheezing, asthma, eczema, or rhinitis), 22 atopy, or a combination thereof.6 Though one cross-sectional and several longitudinal studies have 23 24 assessed the early-life programming of allergic diseases by maternal weight or GWG, they have been 25 limited by small sample sizes (<1000)7,8 and self-reported measures of the exposure or outcome,7–19 which 26 27 have reduced their generalizability and validity. Further, most have focussed on asthma alone,7–14 none 28 have examined anaphylaxis, and none have calculated risk by the length of follow-up time, opting instead 29 30 8,13,17 7,9–12,14–16,18 for aggregate rates (log-linear model), odds (logistic model), or prevalence ratios (log- http://bmjpaedsopen.bmj.com/ 31 19 32 binomial model). As well, none of these studies have been undertaken in Canada, which has a unique 33 multicultural population. This proposed research will attempt to address these evidence gaps by carrying 34 35 out a large population-based study in Canada’s most populous province. 36 37 38 Aims 39 40 We will assess the impact of maternal pre-pregnancy BMI and GWG on the incidence of childhood on September 25, 2021 by guest. Protected copyright. 41 allergic diseases (asthma, rhinitis, atopic dermatitis, and anaphylaxis). Based on previous literature, we 42 43 hypothesize that maternal overweight, obesity, and excess GWG will all increase the risk of allergic 44 diseases in offspring, with GWG incurring the greatest risk. This work may help inform public health 45 46 initiatives for high-risk groups and increase early prevention, identification, and treatment of early 47 childhood morbidity. 48 49 50 51 METHODS AND ANALYSIS 52 Design and Setting 53 54 We will conduct a population-based retrospective cohort study of all singleton live births to residents of 55 Ontario, Canada between 1 April 2012 and 31 March 2014, with follow-up of children to 31 March 2019 56 57 58 59 4 60 https://mc.manuscriptcentral.com/bmjpo BMJ Paediatrics Open Page 6 of 88 bmjpo: first published as 10.1136/bmjpo-2020-000893 on 5 January 2021. Downloaded from MATERNAL WEIGHT AND PEDIATRIC ALLERGIC DISEASE 1 2 3 (Figure 1). The study will be conducted using multiple linked province-wide health databases within the 4 5 secure network environment of ICES (https://www.ices.on.ca/). This protocol was developed following 6 the REporting of studies Conducted using Observational Routinely-collected health Data (RECORD) 7 8 guidelines.20 9 10 Confidential: For Review Only 11 Data Sources and Population 12 13 The birth cohort will be defined using maternal-newborn records from the provincial birth registry, the 14 Better Outcomes Registry & Network (BORN) Information System (BIS). The BIS captures all hospital 15 16 births ≥500g or ≥20 weeks of gestation in Ontario, as well as detailed clinical and demographic 17 information about the birth and the mother. Deterministic and probabilistic methods have been used to 18 19 link the BIS database to health administrative databases at ICES, enabling follow-up of offspring health 20 21 outcomes into early childhood (5–7 years of age). All residents of Ontario are covered by publicly funded 22 universal healthcare and are eligible to access the services captured in the health administrative databases. 23 24 The health administrative databases at ICES to be used in this study include: the Canadian Institute for 25 Health Information (CIHI) Discharge Abstract Database (DAD); the CIHI National Ambulatory Care 26 27 Reporting System (NACRS); the Ontario Health Insurance Plan (OHIP) database; the Ontario Asthma 28 Surveillance Information System (ASTHMA); the Ontario Drug Benefit (ODB) database; the Ontario 29 30 portion of the federal Immigration, Refugees and Citizenship Canada (IRCC) Permanent Resident http://bmjpaedsopen.bmj.com/ 31 32 Database; and the Ontario Marginalization Index (ON-Marg). All data sources and reasons for use are 33 displayed in Figure 2. The study population will be restricted by sample exclusions (non-Ontario resident; 34 35 stillbirth; twin or higher-order multiple birth; mother’s age outside probable range [i.e., <12 years or >50 36 years]; and infant died on date of birth) and administrative exclusions (duplicate records in BORN; 37 38 invalid linkages and linkage warnings; invalid infant and mother identifiers; mothers without continuous 39 40 OHIP eligibility throughout pregnancy; and infants who did not have records of health care eligibility on September 25, 2021 by guest.

Figure 3 displays temporal aspects of the study design relating to eligibility, 42 43 variable measurement, and follow-up; this figure was previously proposed by Schneeweiss and 44 colleagues.21 45 46 47 Exposures 48 49 The primary exposures of interest will be maternal pre-pregnancy BMI and GWG. Ascertainment. Pre- 50 51 pregnancy BMI will be calculated by dividing pre-pregnancy weight (kg) by height (m), squared. For 52 approximately 70% of participants, data on maternal weight will be available from the first prenatal 53 54 screening visit at around 12 weeks of gestation (available from the Prenatal Screening Ontario [PSO] 55 encounter within the BIS database), where it is likely to have been objectively measured. From this, pre- 56 57 58 59 5 60 https://mc.manuscriptcentral.com/bmjpo Page 7 of 88 BMJ Paediatrics Open bmjpo: first published as 10.1136/bmjpo-2020-000893 on 5 January 2021. Downloaded from MATERNAL WEIGHT AND PEDIATRIC ALLERGIC DISEASE 1 2 3 pregnancy weight will be estimated by subtracting the typical first trimester weight gain (1.64kg),22 as 4 5 done previously.23 Ideally pre-pregnancy measurements, which are rare in health administrative database 6 studies, would be available; still, it has been recently noted that weight at first prenatal screening offers a 7 8 valid estimate of pre-pregnancy weight after adjustment for first trimester weight gain.24 For subjects with 9 no record in the PSO database (due to no prenatal screening), maternal pre-pregnancy weight will be 10 Confidential: For Review Only 11 captured from the Labour & Birth encounter within the BIS database, where the data may be based on 12 13 either self-report or objective measurement. GWG will be calculated by subtracting maternal pre- 14 pregnancy weight from weight recorded at delivery. Measures. Pre-pregnancy BMI will be classified 15 16 according to World Health Organization categories: underweight (<18.5 kg/m2), normal weight (18.5– 17 24.9 kg/m2), overweight (25.0–29.9 kg/m2) or obese (≥30.0 kg/m2).1 The Institute of Medicine (IOM) 18 19 recommendations for weight gain during pregnancy suggest total weight gain for singleton pregnancies 20 21 should not exceed 12.5–18 kg, 11.5–16 kg, 7–11.5 kg, or 5–9 kg based on pre-pregnancy BMI category, 22 respectively.25 However, these recommendations do not account for gestational length. To do so, we will 23 24 follow previously published methods26 to establish expected GWG based on IOM recommendations for 25 weight gain by trimester and pre-pregnancy BMI, and calculate the ratio of actual to expected GWG. We 26 27 will then employ the recommended ratio ranges calculated by Guo and colleagues26 to classify GWG into 28 three categories: inadequate, adequate, or excess weight gain. These ratio ranges were determined by 29 30 dividing the lower and upper limits of the IOM GWG recommendations by the expected GWG within http://bmjpaedsopen.bmj.com/ 31 32 each pre-pregnancy BMI category. Pre-pregnancy BMI and GWG (calculated as the difference between 33 observed and expected weight gain, based on the above methods) will also be examined as continuous 34 35 variables. 36 37 38 Outcomes 39 40 Asthma, rhinitis, atopic dermatitis, and anaphylaxis will be examined separately during follow-up based on September 25, 2021 by guest.

ICD codes and algorithms can be found in Supplementary File A. 44 We will employ a time-to-first-event analysis for all outcomes, in which the follow-up period will begin 45 46 at birth and continue until either the outcome occurs, the infant dies or becomes ineligible to receive 47 healthcare services (with a 90-day grace period), or until the end of the study period, whichever comes 48 49 first. Follow-up time (person-days) will be calculated for each event separately. Asthma. Using a 50 51 validated algorithm, the ASTHMA database will identify infants with asthma diagnoses. The algorithm 52 requires ≥1 hospitalization and/or ≥2 ambulatory care visits for asthma within two years, where the 53 54 earliest claim is deemed the date of diagnosis.27 The algorithm was first validated among children in 2006 55 (ages 1–8; sensitivity: 91%, specificity: 83%),28 and was recently re-validated in 2019 among younger 56 57 58 59 6 60 https://mc.manuscriptcentral.com/bmjpo BMJ Paediatrics Open Page 8 of 88 bmjpo: first published as 10.1136/bmjpo-2020-000893 on 5 January 2021. Downloaded from MATERNAL WEIGHT AND PEDIATRIC ALLERGIC DISEASE 1 2 3 children (ages 1–5; sensitivity: 81%, specificity: 90%).29 Since the accuracy of asthma diagnoses among 4 5 young infants is debated, records fulfilling the algorithm for asthma diagnosis before the age of 6 months 6 will be disregarded unless a further hospitalization or ambulatory care visit for asthma is detected after 12 7 8 months of age.30 Rhinitis and atopic dermatitis. Rhinitis and atopic dermatitis cases will be captured by 9 an algorithm from Hill and colleagues, which requires ≥2 care visits occurring ≥6 months apart and where 10 Confidential: For Review Only 11 the date of diagnosis is the first visit. These algorithms displayed positive predictive values of 100% and 12 31 13 90% based on chart review, respectively (no sensitivity or specificity measures were published). 14 Anaphylaxis. We will employ criteria A and B from the algorithm by Walsh and colleagues32 to detect 15 16 anaphylaxis in inpatient, emergency department, and outpatient encounters using ICD codes for diagnoses 17 and symptoms. In a validation study, this algorithm performed better than those of previous studies, with 18 19 a sensitivity of 91% and positive predictive value of 67%.32 Some modifications were made to the 20 21 algorithm for our study, including the removal of the three procedure/intervention codes which are not 22 available in our outpatient dataset and the inclusion of an ICD code for anaphylactic shock due to food 23 24 reaction due its high prevalence in childhood. 25 26 27 Covariates and Confounders 28 The following covariates and potential confounders will be examined: maternal characteristics (maternal 29 30 country of birth [for recent immigrants, otherwise Canada], maternal age at birth, maternal smoking, http://bmjpaedsopen.bmj.com/ 31 32 parity, maternal asthma and other pre-existing medical conditions, and use of drugs, alcohol, or 33 medications during pregnancy); neighbourhood characteristics, using residential postal codes linked to 34 35 Census data (neighbourhood marginalization index and rural residence); and birth or infant characteristics 36 (mode of delivery, complications of pregnancy, season of birth, sex of infant, gestational age, birth 37 38 weight, and exclusive breastfeeding at time of hospital discharge).

The results from the imputed datasets will be combined to produce 44 final estimates, following best practices.33 45 46 47 Statistical Analyses 48 49 Sample characteristics will be presented as frequencies and proportions for categorical variables and 50 51 means or medians for continuous variables (with measures of spread, such as standard deviation or inter- 52 quartile range), overall and stratified by exposure group to present potential confounding.34 Between 53 54 group-differences will be assessed by standardized differences, which denote differences in units of 55 standard deviation. Standardized differences greater than 10% indicate an imbalance between the 56 57 58 59 7 60 https://mc.manuscriptcentral.com/bmjpo Page 9 of 88 BMJ Paediatrics Open bmjpo: first published as 10.1136/bmjpo-2020-000893 on 5 January 2021.

Crude and adjusted analyses (utilizing 10 Confidential: For Review Only 11 multivariable analysis methods) will assess differences in pediatric allergic disease incidence: 1) between 12 13 infants born to underweight, overweight, or obese mothers compared to those born to mothers with 14 normal pre-pregnancy weight; and 2) between infants born to mothers who fell below or exceeded 15 16 recommended GWG guidelines compared to those who met the GWG recommendation. Models will be 17 adjusted for maternal age, maternal birth country, maternal pre-pregnancy health conditions, maternal 18 19 medication and substance use during pregnancy, neighbourhood characteristics, and parity—the minimal 20 21 sufficient adjustment set identified in the DAG (Figure 4). Cox models will account for repeated 22 pregnancies during the 2012–2014 period by adjusting the variance through generalized estimating 23 24 equation (GEE) methods.36 The following effect measure modifiers have been selected a priori: pre- 25 pregnancy BMI (when GWG is the exposure), GWG (when pre-pregnancy BMI is the exposure), and 26 27 infant sex. If estimates between strata are qualitatively different, we will introduce an interaction term or 28 report strata-specific estimates based on published guidelines.37 The proportional hazards assumption of 29 30 the Cox models will be assessed through Schoenfeld residual plots and Wald tests for interaction between http://bmjpaedsopen.bmj.com/ 31 32 exposure status and time. In secondary analyses, continuous measures of the exposures will be used and 33 restricted cubic splines will be added to the Cox proportional-hazards models to account for non-linear 34 35 associations between exposures and outcomes.38 All analyses will be conducted using SAS version 9.4 36 (SAS Institute, Cary, NC). 37 38 39 40 Pre-planned Sensitivity Analyses on September 25, 2021 by guest.

To account for potential residual confounding by maternal propensity to access healthcare 48 49 services, we will assess typical maternal healthcare utilization through outpatient visits in the 50 51 OHIP database during a one-year look-back period before pregnancy and adjust for this in our 52 models. Only mothers who were continuously eligible for OHIP during the look-back period will 53 54 be included. 55 56 57 58 59 8 60 https://mc.manuscriptcentral.com/bmjpo BMJ Paediatrics Open Page 10 of 88 bmjpo: first published as 10.1136/bmjpo-2020-000893 on 5 January 2021.

To ensure that self-reported maternal weight does not bias our results, a subgroup analysis will be 5 6 undertaken among the subset of participants with pre-pregnancy weight recorded in the prenatal 7 encounter of the BIS database. 8 9 10 11 AssessmentConfidential: of Potential Outcome Misclassification For Review Only 12 5. Researchers from Denmark created39 and validated40 algorithms that employ hospital diagnoses 13 14 and dispensed prescription medications to identify cases of rhinitis (sensitivity: 84%, specificity: 15 82%) and atopic dermatitis (sensitivity: 74%, specificity: 73%) in childhood compared to parental 16 17 reports of physician diagnoses. In our study, data on prescription medications dispensed can only 18 be ascertained for the subset of participants who were covered by the provincial drug funding 19 20 system (Ontario Drug Benefit, ODB). Residents of Ontario qualify for ODB if they are either ≥65 21 22 years old or are enrolled in one of the following provincial programs: home care and community 23 services, employment assistance, assistance for persons with disabilities, or assistance with 24 25 prescription-drug costs for those in financial need; starting on 1 January 2018, ODB was 26 extended to any resident of Ontario covered by OHIP+: Children and Youth Pharmacare (≤24 27 28 years old). We will run a sensitivity analysis using these derived algorithms for rhinitis and atopic 29 30 dermatitis in the subgroup of children whose families qualified for ODB (see Supplementary File http://bmjpaedsopen.bmj.com/ 31 A for algorithms and codes). 32 33 6. We believe that the algorithms employed may result in non-differential outcome 34 misclassification, which usually produces bias towards the null or, in some circumstances, no 35 36 bias.41 A probabilistic bias analysis will be conducted to evaluate the influence of this 37 misclassification, following published methods.42 38 39 40 on September 25, 2021 by guest.
