1 2 3 4 5 Abstract 6 Objective: To evaluate whether early life adiposity has an independent effect on later life 7 8 disease risk or whether its influence is mediated by adulthood body mass index (BMI). 9 10 Design: Two-sample univariable and multivariable Mendelian randomization. 11 Confidential: For Review Only 12 Setting: The UK Biobank (UKB) prospective cohort study and four large-scale genome-wide 13 association study (GWAS) consortia. 14 15 Participants: 453,169 participants enrolled in the UKB and a combined total of over 16 17 700,000 individuals from different GWAS consortia. 18 19 Exposures: Measured BMI during adulthood (mean age: 56.5) and self-reported adiposity 20 at age 10. 21 22 Main outcome measures: Coronary artery disease (CAD), type 2 diabetes (T2D), breast 23 24 cancer and prostate cancer. 25 26 Results: Individuals with genetically predicted higher BMI in early life had increased odds 27 of CAD (OR:1.49, 95% CI:1.33-1.68) and T2D (OR:2.32, 95% CI:1.76-3.05) based on 28 29 univariable MR (UVMR) analyses. However, there was little evidence of a direct effect (i.e. 30 31 not via adult BMI) based on multivariable MR (MVMR) estimates (CAD OR:1.02, 95% CI:0.86- 32 33 1.22, T2D OR:1.16, 95% CI:0.74-1.82). In the MVMR analysis of breast cancer risk, there was 34 35 strong evidence of a protective direct effect for early BMI (OR:0.59, 95% CI:0.50-0.71), 36 although adult BMI did not appear to have a direct effect on this outcome (OR:1.08, 95% 37 38 CI:0.93-1.27). Adding age of menarche as an additional exposure provided weak evidence of 39 40 a total causal effect (UVMR OR:0.98, 95% CI:0.91-1.06) but strong evidence of a direct causal 41 42 effect, independent of early and adult BMI (MVMR OR:0.90, 95% CI:0.85-0.95). Weak 43 evidence of a causal effect was observed in the MVMR analysis of prostate cancer (early life 44 45 BMI OR:1.06, 95% CI:0.81-1.40, adult BMI OR:0.87, 95% CI:0.70-1.08). 46 47 Conclusions: Our findings suggest that increased CAD and T2D risk attributed to early life 48 49 adiposity can be mitigated if individuals reduce their weight in later life. However, having a 50 low BMI during childhood may increase risk of breast cancer regardless of changes to weight 51 52 in later life, with timing of puberty also putatively playing an important role. 53 54 55 56 57 58 59 60 https://mc.manuscriptcentral.com/bmj Page 3 of 173 BMJ

1 2 3 4 5 Introduction 6 Childhood obesity is now widely recognised as a global public health crisis, yet its prevalence 7 8 continues to rise1 2. Having a high body mass index (BMI) in early life is thought to increase 9 10 the risk of various health conditions, such as coronary artery disease (CAD)3, type 2 diabetes 11 Confidential: For Review Only 4 5-7 12 (T2D) and different types of cancer . Whether an individual can reverse the impact of 13 childhood obesity through lifestyle modifications is unclear, particularly given that 14 15 individuals who are obese in early life tend to remain obese in adulthood8. This makes it 16 17 challenging to discern whether early life adiposity has an independent and lasting influence 18 19 on disease risk, or if its effect is entirely mediated by later life adiposity. If the latter is the 20 case, then the potential adverse consequences of childhood obesity could be avoided by 21 22 attaining and maintaining a healthy weight in adulthood. 23 24 25 26 Mendelian randomization (MR) is an approach that can help address such issues, by 27 harnessing genetic variants as instrumental variables to infer causality amongst correlated 28 29 traits9 10. As an individual’s genotype is established at zygote formation then genetic 30 31 variation is robust to reverse causation, and confounding is considerably less evident than 32 11 33 in conventional observational studies . Furthermore, recent methods have been developed 34 35 to disentangle whether several exposures influence an outcome along the same causal 36 pathway or whether they have independent effects12 13. One of these developments is known 37 38 as multivariable Mendelian randomization12 14. 39 40 41 42 We have undertaken an MR study to evaluate whether genetically predicted early life BMI 43 has an effect on 4 disease outcomes that have been linked to childhood adiposity: CAD, T2D, 44 45 breast cancer and prostate cancer3 4 7 15. Genetic instruments were identified by undertaking 46 47 a genome-wide association study (GWAS) of 453,169 individuals from the UK Biobank study 48 49 with measures of BMI in adulthood (mean age=56.5) who also reported their body size at 50 age 10. This allowed us to conduct both univariable and multivariable MR analyses to discern 51 52 whether the predicted causal influence of early life BMI has an independent effect on disease 53 54 risk or whether it is mediated through later life BMI. 55 56 57 58 59 60 https://mc.manuscriptcentral.com/bmj BMJ Page 4 of 173

1 2 3 We postulate that, if early life BMI has a causal influence on disease risk, then there are likely 4 5 3 main categories that such effects could be grouped into after accounting for adult BMI in a 6 7 multivariable framework (Figure 1). Firstly, the influence of early life BMI on disease risk 8 9 may be mediated by later life BMI. As such, early life BMI only has an indirect effect on 10 disease risk via adult BMI, which for example could be attributed to individuals with a high 11 Confidential: For Review Only 12 BMI at age 10 remaining overweight into adulthood (Figure 1-1). Secondly, early life BMI 13 14 may have only an independent (i.e. direct) effect on disease risk, which is not mediated 15 16 through adult BMI (Figure 1–2), or it may also be plausible that BMI at separate timepoints 17 may both influence disease risk via alternate causal pathways (i.e. early life BMI has both a 18 19 direct and an indirect effect on outcome, Figure 1–3). Additional descriptions of direct, 20 21 indirect and total effects within a multivariable framework can be found in Supplementary 22 23 Figure 1. 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 https://mc.manuscriptcentral.com/bmj Page 5 of 173 BMJ

1 2 3 4 5 Methods 6 7 The UK Biobank and disease outcome datasets 8 Between 2006 to 2010 the UK Biobank study enrolled 500,000 individuals aged between 40 9 10 and 69 at baseline across 22 assessments centres in the United Kingdom16. Data were 11 Confidential: For Review Only 12 collected based on clinical examinations, assays of biological samples, detailed information 13 17 14 regarding self-reported health characteristics and genome-wide genotyping . BMI was 15 derived using height (measured in whole centromeres) and weight (to the nearest 0.1kg) at 16 17 baseline. Participants were also asked ‘When you were 10 years old, compared to average 18 19 would you describe yourself as thinner, plumper or about average?’. Hereafter these 20 21 measures are referred to as ‘adult BMI’ and ‘early life BMI’ respectively. 22 23 24 Only individuals with both BMI measures were included in analyses. Adult BMI was 25 26 converted into a categorical variable with 3 groups based on the same proportions as the 27 28 early life BMI variable (i.e. ‘thinner’, ‘plumper’ and ‘about average’). This was to ensure that 29 both measures were as comparable as possible. Effect estimates from our results can be 30 31 interpreted as the increase in odds conferred per additive change in BMI category. In total, 32 33 12,370,749 genetic variants in up to 463,005 individuals were available for analysis as 34 18 19 20 35 described previously . Effect estimates for genome-wide genetic variants on CAD , T2D , 36 breast cancer21 and prostate cancer22 were obtained using findings from large-scale 37 38 consortia which did not include data from the UK Biobank (Supplementary Table 1). Since 39 40 earlier age at menarche is an established risk factor for breast cancer we also obtained 41 42 summary statistics from a GWAS of age of menarche, which was used in additional analyses 43 relating to this outcome23. 44 45 46 47 48 Statistical analysis 49 50 51 Identifying instruments by undertaking a genome-wide association study 52 53 The association between genetic variants across the and both measures of 54 18 24 55 BMI were assessed using the software BOLT-LMM . This approach applies a Bayesian 56 57 58 59 60 https://mc.manuscriptcentral.com/bmj BMJ Page 6 of 173

1 2 3 linear mixed model to account for both relatedness and population stratification. Age at 4 5 baseline and type of genotyping array were added as covariates in the model. Analyses were 6 7 undertaken 3 times, once in all eligible individuals after additionally adjusting for sex, and 8 9 then in females and males separately. This allowed us to identify genetic variants which 10 could be used as instrumental variables for outcomes based on a female-only population (i.e. 11 Confidential: For Review Only 12 breast cancer), a male-only population (i.e. prostate cancer) and mixed populations (i.e. CAD 13 14 and T2D). Early life BMI analyses were additionally adjusted for month of birth as we 15 16 hypothesized that an individual’s relative age within their school year may bias their 17 reporting. Effect estimates from this analysis were used in the subsequent Mendelian 18 19 randomization analyses. 20 21 22 25 23 Linkage disequilibrium (LD) clumping was undertaken using the software PLINK to 24 identify independent variants from our GWAS. This was based on a threshold of r2 <0.001 25 26 using genotype data from European individuals (CEU) from phase 3 (version 5) of the 1000 27 28 genomes project as a reference panel26. For independent variants associated with either 29 -08 30 early life or adult BMI in our GWAS of all participants (based on P < 5 x 10 ), we compared 31 their effect estimates between timepoints. This was undertaken by stacking observations 32 33 (i.e. so that each individual had 2 BMI measurements) and then regressing the categorical 34 35 BMI outcomes on each variant in turn adjusting for age, sex and time (i.e. early life or 36 37 adulthood). This analysis was then repeated but also adjusting for the interaction between 38 genetic variant and time. To account for multiple testing, we applied a Bonferroni correction 39 40 to the p-values of the interaction terms (i.e. P < 0.05/number of individual variants assessed) 41 42 as a heuristic to highlight genetic loci with the strongest evidence of an interaction with time. 43 44 This analysis was undertaken to demonstrate that various genetic variants seemingly appear 45 46 to have a stronger influence on BMI at different timepoints in the life courses. 47 48 49 We also undertook LD score regression27 to evaluate the genetic correlation between the two 50 51 measures of BMI from our analysis with directly measured body mass index28 and childhood 52 29 30 53 obesity using LD hub . In doing so, we attempted to validate our early life measure of BMI 54 by demonstrating that it is more strongly correlated with measured child obesity than adult 55 56 BMI, given that is was derived using questionnaire data. 57 58 59 60 https://mc.manuscriptcentral.com/bmj Page 7 of 173 BMJ

1 2 3 4 5 Mendelian randomization 6 7 Univariable MR analyses were conducted using the MR-Base platform31 to investigate total 8 9 effect estimates between genetically predicted age 10 BMI and adult BMI individually with 10 11 each diseaseConfidential: outcome in turn. This was basedFor on effectReview estimates using Only the inverse-variance 12 weighted (IVW) method32. Effect estimates on early life BMI were used for the analysis with 13 14 additional adjustment for month of birth. However, the “total” effect of adult BMI should be 15 16 interpreted with caution. There is likely to be strong correlation between genetic 17 18 determinants of early and adult BMI, and thus the total effect of adult BMI is likely to suffer 19 from what will manifest as pleiotropy if there is also a direct effect of early BMI on the 20 21 outcome. In the main manuscript we only discuss the total effect of early BMI, and direct 22 23 effects of early and adult BMI, for this reason. A direct acyclic graph illustrating direct, 24 25 indirect and total effects as investigated within a multivariable MR framework can be found 26 in Supplementary Figure 1. 27 28 29 30 Multivariable MR analyses were undertaken to estimate the direct effect of early life BMI on 31 32 each outcome in turn. Variants from the univariable analysis were used again here after 33 undertaking further LD clumping to account for instrument correlation between the two 34 35 sets. We also undertook a negative control analysis with early life and adult BMI as exposures 36 37 in a multivariable framework and age at menarche as an outcome using findings from a 38 23 39 GWAS published prior to the release of UK Biobank . As depicted in Supplementary Figure 40 2, we hypothesized that early life BMI should only influence age at menarche directly in this 41 42 framework as an individual’s adult BMI cannot influence timing of puberty. As such, direct 43 44 and total effect derived from a univariable framework should be comparable for early life 45 46 BMI on this outcome, whereas evidence of an indirect effect (i.e. via adult BMI) should be 47 weak. Furthermore, we undertook a sensitivity analysis for the breast cancer outcome to 48 49 discern whether timing of puberty may also play a role in disease risk. This involved 50 51 repeating analyses on breast cancer with age at menarche as a third exposure (along with 52 53 early life and adult BMI). Univariable and Multivariable MR analyses were also repeated 54 using findings derived from ER-positive and ER-negative cases of breast cancer. Finally, we 55 56 57 58 59 60 https://mc.manuscriptcentral.com/bmj BMJ Page 8 of 173

1 2 3 undertook simulated analyses to investigate how misclassification for early life BMI would 4 5 affect our results (Supplementary Note 1). 6 7 8 9 All analyses were undertaken using R (version 3.5.1). Plots were created using the packages 10 ‘ggplot2’33 and ‘metafor’34. 11 Confidential: For Review Only 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 https://mc.manuscriptcentral.com/bmj Page 9 of 173 BMJ

1 2 3 4 5 Results 6 7 A genome-wide association study of early life and adult body mass index 8 In a GWAS of 453,169 UK Biobank individuals, there were 295 and 557 independent 9 10 associations detected with early life and adult BMI respectively based on conventional 11 Confidential: For Review Only 12 genome-wide corrections (i.e. P < 5 x10-08) (Supplementary Tables 2 & 3). LD score 13 14 regression analyses identified strong genetic correlation between our derived early life 15 measure of BMI and a previous GWAS of childhood obesity (rg=0.85) (Supplementary Figure 16 17 3). In contrast, our adult BMI measure was considerably more strongly genetically correlated 18 19 with a previous GWAS of adult BMI (rg=0.96) than to childhood obesity (rg=0.64). Evaluating 20 21 the difference between the genetic variant associations at the two different timepoints 22 suggested that 75 genetic variants had stronger effect estimates on BMI in adulthood 23 24 compared to early life, whereas 23 genetic variants had a stronger effect in early life 25 26 compared to adult BMI estimates (at P < 7.19 x 10-05 (i.e. 0.05/694 tests), Supplementary 27 28 Table 4). Demonstrating that the magnitude of effect for these genetic variants differs with 29 respect to early life and adult BMI suggests that they can be separated as two exposures in a 30 31 multivariable framework. 32 33 34 35 Figure 2 illustrates findings from both GWAS using a bi-directional Manhattan plot 36 (sometimes referred to as a ‘Miami plot’) where some examples of timepoint specific effects 37 38 have been highlighted. Repeating our GWAS stratified by sex identified 135 and 215 variants 39 40 which survived GWAS corrections (i.e. P < 5 x 10-08) in females only with early life and adult 41 42 BMI respectively (n=246,511) (Supplementary Tables 5 & 6). In the male specific analysis, 43 there were 69 genetic variants associated with early life BMI and 159 genetic variants 44 45 associated with adult BMI (n=206,658) (Supplementary Tables 7 & 8). Repeating early life 46 47 BMI analyses with additional adjustment for month of birth did not appear to materially 48 49 influence overall findings (Supplementary Table 9-11). 50 51 52 53 54 55 56 57 58 59 60 https://mc.manuscriptcentral.com/bmj BMJ Page 10 of 173

1 2 3 Univariable and multivariable Mendelian randomization analyses 4 5 Univariable analyses provided strong evidence that early life BMI is associated with CAD risk 6 7 (UVMR OR:1.49, 95% CI:1.33-1.68). However, the direct effect of early life BMI (i.e. not 8 9 mediated via adult BMI) was much smaller than the total effect (MVMR OR:1.02, 95% 10 11 CI:0.86-1.22),Confidential: whereas strong evidence For of a direct Review effect was identified Only for adult BMI 12 (OR:1.82, 95% CI:1.59-2.09). Similar findings were identified for analyses on T2D, as the 13 14 magnitude of the direct causal effect for early life BMI was much smaller than the total effect 15 16 when modelled simultaneously with adult BMI (early life BMI OR:1.16, 95% CI:0.74-1.82, 17 18 adult BMI OR:2.80, 95% CI:1.89-4.15). Effect estimates from both univariable and 19 multivariable MR analyses are illustrated in Figure 3 and a full list can also be found in 20 21 Supplementary Table 12. 22 23 24 25 The negative control analysis with age at menarche as an outcome provided strong evidence 26 in the univariable analysis that early life BMI influences timing of puberty (Beta:- 0.93, 95% 27 28 CI:-0.66 to -1.20). Including adult BMI in a multivariable framework along with childhood 29 30 BMI found that the direct effect estimate for childhood BMI was essentially unchanged, 31 32 whilst adulthood BMI was not seen to influence age of menarche (Table 1). These findings 33 reflect the scenario depicted in Supplementary Figure 2, suggesting that early life BMI can 34 35 only effect timing of puberty directly and not indirectly via adult BMI (given that it occurs at 36 37 an earlier timepoint in life course). 38 39 40 For breast cancer, there was strong evidence in the univariable analysis that higher 41 42 genetically predicted early life BMI leads to reduced risk of this outcome (OR:0.63, 95% 43 44 CI:0.55-0.72). Analysing both measures of BMI in a multivariable framework found that the 45 46 indirect effect estimate via adult BMI (OR:1.08, 95% CI:0.93-1.27) was smaller in magnitude 47 than the direct protective effect of early life BMI (OR:0.59, 95% CI:0.50-0.71). Similar 48 49 findings were identified in the analysis of ER-positive and ER-negative cases of breast cancer 50 51 (Supplementary Table 13). 52 53 54 55 56 57 58 59 60 https://mc.manuscriptcentral.com/bmj Page 11 of 173 BMJ

1 2 3 Evaluating the relationship between genetically predicted age at menarche and breast 4 5 cancer in a univariable analysis provided weak evidence of a total effect (OR:0.98, 95% 6 7 CI:0.90-1.06). However, when modelled together with both early and adult BMI (i.e. all 3 8 9 exposures in the multivariable model) there was strong evidence that later age at menarche 10 may lower the risk of breast cancer (OR:0.90, 95% CI:0.85-0.95). Effect estimates for 11 Confidential: For Review Only 12 predicted early life BMI had a larger effect in this multivariable analysis compared to the 13 14 direct effect of adult BMI (Table 1). There was very weak evidence that early life BMI has a 15 16 predicted causal effect on prostate cancer either directly (OR:1.06, 95% CI:0.81-1.40). or 17 indirectly via adult BMI (OR:0.87, 95% CI:0.70-1.08). 18 19 20 21 Early life BMI is self-reported later in life and so is likely to be subject to misclassification 22 23 which will not affect our measure of adult BMI. We therefore conducted a simulation to 24 identify how such misclassification, affecting only one exposure, will influence the effect 25 26 estimation in our multivariable MR analyses. Our results (see Supplementary Note 1) show 27 28 that misclassification weakens the strength of association between the SNPs and our 29 30 measure of early life BMI and so potentially biases the estimated effect of early life BMI in 31 our multivariable MR analysis but does not introduce bias into the estimated effect between 32 33 later life BMI and the outcomes. The results also show even with misclassification the effect 34 35 of early life BMI in the multivariable MR estimation is not biased when it has a null effect on 36 37 the outcome. 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 https://mc.manuscriptcentral.com/bmj BMJ Page 12 of 173

1 2 3 4 5 Discussion 6 7 8 Interpretation of findings 9 10 In this study we have examined the influence of early life adiposity on disease risk and 11 Confidential: For Review Only 12 whether this putative causal effect occurs independently (“direct effect”) or via the same 13 14 causal pathway (“indirect effect”) as later life BMI. Our univariable MR analysis suggested 15 that genetically predicted early life BMI increases risk of coronary artery disease and type 2 16 17 diabetes. However, when analysed together with adult BMI in a multivariable framework the 18 19 direct effect estimates for early life BMI were of considerably reduced and essentially null 20 21 magnitude in comparison to the estimates of the total effects, suggesting that its influence on 22 these outcomes is mediated by later life BMI (as portrayed in the ‘Indirect effect of early life 23 24 BMI only’ diagram in Figure 1). These findings imply that observed associations between 25 26 early life obesity and increased coronary artery disease and type 2 diabetes risk are likely 27 28 attributed to individuals with a high BMI during childhood remaining overweight into later 29 life. This suggests that a window of opportunity exists to mitigate the detrimental impact of 30 31 early life BMI on risk of these disease outcomes35 36. This corroborates findings from some 32 33 previous research suggesting that there is no persistent influence of childhood obesity on 34 37 38 35 risk of type 2 diabetes and cardiovascular disease, unless adiposity is sustained . 36 Furthermore, these findings highlight the importance taking into account adult BMI in order 37 38 to assess whether childhood adiposity has a direct or persistent effect on disease risk over 39 40 the life course39 40. 41 42 43 Our results also provide strong evidence that early life BMI has a protective effect on breast 44 45 cancer risk as has been previously reported by both observational and MR studies which 46 47 have not previously taken into account adult BMI41-44. This was identified both as a total and 48 49 direct effect using univariable and multivariable MR analyses respectively, suggesting that 50 the effect of early life BMI may persist into later life regardless of any interventions that 51 52 influence BMI variation. Furthermore, reported protective effect estimates between later life 53 54 BMI and breast cancer risk may be attributed to effects from childhood. We note however 55 56 that this effect requires further investigation in subpopulations of pre- and post-menopausal 57 58 59 60 https://mc.manuscriptcentral.com/bmj BMJ Page 14 of 173

This is particularly crucial given 4 5 observational evidence suggesting that higher BMI increases the risk of invasive breast 6 7 cancer in post-menopausal women45. 8 9 10 As an additional validation of our multivariable framework, we undertook a negative control 11 Confidential: For Review Only 12 analysis to investigate the effect of early life BMI on at menarche in both a univariable and 13 14 multivariable framework accounting for adult BMI. We found that estimates were consistent 15 16 from both analyses for early life BMI, whereas the effect estimates for adult BMI in the 17 multivariable analyses had a much smaller magnitude of effect in comparison. This provides 18 19 a powerful proof of concept for our analytical framework, given that BMI can only influence 20 21 timing of puberty in early life whereas adult BMI cannot as it occurs earlier in the life course. 22 23 24 We also undertook an additional analysis to investigate timing of puberty with respect to the 25 26 putative predictive effect of early life BMI on breast cancer risk. To do this, we incorporated 27 28 age at menarche as an additional exposure in our multivariable MR analysis. Our findings 29 30 corroborate similar analyses undertaken using a multivariable framework, which suggests 31 that later age at menarche has a protective effect on breast cancer risk but only when 32 33 accounting for early life BMI46. However, there is strong evidence from the literature of a 34 35 relationship between timing of puberty and later life BMI47 48. Notably, our results build upon 36 37 previous findings by modelling age 10 and adult BMI as two separate exposures, due to the 38 direct effect of age 10 BMI providing strong evidence of a protective effect when accounting 39 40 for age at menarche. Similar observational findings have been reported recently in 41 42 premenopausal women after adjusting for age at menarche49. Developing insight into the 43 44 underlying biological mechanisms explaining this effect may therefore have important 45 46 therapeutic implications. 47 48 49 We were unable to support previous evidence of an effect between genetically predicted BMI 50 51 and prostate cancer risk50 51. This relationship is notoriously complex due to the effect of 52 53 obesity on various hormones in males, such as an inverse relationship with prostate specific 54 antigen52 and a positive relationship with estrogen concentrations53. This outcome is 55 56 therefore worth revisiting using forthcoming findings from large-scale GWAS of prostate 57 58 59 60 https://mc.manuscriptcentral.com/bmj Page 15 of 173 BMJ

1 2 3 cancer when they become available, using this study’s analytical framework. A greater 4 5 number of genetic instruments in males only is also likely to improve power for future 6 7 endeavours. Evaluating the influence of pubertal development on this outcome would also 8 54 9 be a worthwhile undertaking . 10 11 Confidential: For Review Only 12 We used univariable Mendelian randomization to estimate total effects of early BMI, and 13 14 multivariable Mendelian randomization to estimate direct effects of early and adult BMI. In 15 16 theory, the univariable estimate of the effect of adult BMI (the total effect) and the 17 multivariable estimate (the direct effect) should be equal. However, if some genetic variants 18 19 cause both early and adult BMI (albeit with different effect sizes), and early BMI has a direct 20 21 effect on the outcome, then this will potentially generate pleiotropy in the univariable 22 23 estimate of adult BMI. This can be seen in the univariable estimate of the effect of adult BMI 24 on breast cancer, which is quite different to the multivariable estimate, probably due to the 25 26 direct effect of early BMI on breast cancer. For CAD, where there is no direct effect of early 27 28 BMI on the outcome, then the univariable and multivariable effects of adult BMI are the same. 29 30 This demonstrates one of the issues with Mendelian randomization of time-varying 31 exposures – the univariable analyses cannot identify critical or sensitive periods of exposure, 32 33 but only an effect of a difference in the cumulative lifetime exposure55 56. Moreover, As 34 35 outlined in all the diagrams depicted in Figure 1, we assume that childhood BMI has an effect 36 37 on adulthood BMI in all scenarios. Therefore, individuals who (for example) lower their BMI 38 between childhood and adulthood may effectively break this mediated causal chain and 39 40 reduce their elevated risk of diseases such as coronary heart disease or type 2 diabetes. 41 42 43 44 Strengths and limitations of this study 45 46 47 The key strengths of our investigation include the large number of individuals from the UK 48 49 Biobank study with measures of both early and later life adiposity (n=453,169). This sample 50 size is unprecedented compared to previous endeavours in the field, although we note that 51 52 a caveat to this is having to rely on questionnaire-based data for the age 10 variable. As such 53 54 there will likely be additional measurement error when analysing this exposure. The 55 56 statistical power in our GWAS therefore comes at the expense of precision, although despite 57 58 59 60 https://mc.manuscriptcentral.com/bmj BMJ Page 16 of 173

1 2 3 this we were able to recapitulate evidence of association between genetic variants and early 4 5 life BMI measurements in the literature57 58. 6 7 8 9 Harnessing large-scale summary statistics from GWAS using two-sample MR is another 10 strength of this study. This circumvents the necessity of having both our exposures and 11 Confidential: For Review Only 12 outcomes measured in the same sample. Moreover, along with using genetic variants to 13 14 mitigate the influence of confounding and reverse causation, a multivariable MR framework 15 16 has enabled us to investigate the independent effect of early life BMI, which is extremely 17 challenging in an observational setting. Furthermore, although we have focused on 5 18 19 outcomes in this study, future work can adopt a similar approach to us for any outcomes of 20 21 interest for which there are accessible GWAS summary statistics. 22 23 24 Our univariable analysis used all the SNPs associated with each exposure. Although there are 25 26 variations in the SNPs associated with each of early life and adult BMI there is also 27 28 considerable overlap in the SNPs associated with each timepoint. Our univariable MR 29 30 analyses therefore capture pleiotropic effects of the SNPs through the other time point as 31 well as, for childhood BMI, the effect mediated by adult BMI. This is a limitation of our 32 33 univariable MR analyses but highlights the importance of the multivariable MR to 34 35 disentangle the direct effects of child and adult BMI. 36 37 38 A limitation that should be taken into consideration when interpreting our results is that it 39 40 is possible that participants from the UK Biobank may have also contributed to the large- 41 42 scale GWAS whose results were used in this study. Overlapping exposure and outcome 43 44 samples in a two-sample MR analysis may result in overfitting, although currently there is 45 46 no way to robustly discern whether this is the case unless anonymous identifiers between 47 the UK Biobank and GWAS consortium can be linked together59. 48 49 50 51 Conclusions 52 53 54 Using multivariable Mendelian randomization, we have provided strong evidence suggesting 55 56 that early life adiposity has a causal influence on breast cancer risk that acts independently 57 58 59 60 https://mc.manuscriptcentral.com/bmj Page 17 of 173 BMJ

1 2 3 of later life body mass index. Conversely, our results suggest that the positive association 4 5 between early life adiposity and both coronary artery disease and type 2 diabetes is likely 6 7 due to individuals with a high body mass index remaining overweight in later life. Our 8 9 approach therefore yields insight into the mechanistic pathway between early life risk 10 factors such as body mass index and disease outcomes. Furthermore, it provides scope to 11 Confidential: For Review Only 12 differentiate between effects where the conferred risk may not be reversable by achieving 13 14 and maintain a healthy body mass index in adulthood. 15 16 17 18 19 What is already known on this topic? 20 21 - Childhood obesity is known to have a detrimental impact on various health conditions 22 23 and disease risk in later life. 24 25 26 - Body mass index in early life has been associated with increased odds of coronary 27 28 artery disease and type 2 diabetes observationally, but whether this effect is 29 30 immutable or whether lifestyle modifications can help mitigate it is unclear. 31 32 33 - The influence of early life body mass index on risk of other diseases, such as breast 34 35 cancer and prostate cancer, has been previously reported but the causal relationships 36 37 underlying these observations are complex and require further evaluation. 38 39 40 What this study adds? 41 42 - The influence of early life body mass index on odds of coronary artery disease and 43 44 type 2 diabetes was predominantly mediated through later life adiposity, suggesting 45 46 that individuals can reduce the impact of any conferred risk by reducing their relative 47 weight as they enter adolescence. 48 49 50 51 - Body mass index at age 10 had a protective effect on breast cancer risk which is 52 53 independent of later life adiposity, although timing of puberty likely also plays a 54 causal role in this relationship. 55 56 57 58 59 60 https://mc.manuscriptcentral.com/bmj BMJ Page 18 of 173

1 2 3 - Although in this study we have focused on cardiometabolic and cancer outcomes, the 4 5 analytical approach we have used has considerable potential to investigate how risk 6 7 factors trajectories across life influence different types of health outcomes. 8 9 10 11 Confidential: For Review Only 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 https://mc.manuscriptcentral.com/bmj Page 19 of 173 BMJ

This 34 analysis was undertaken as a negative control, given that early life BMI can only influence timing of 35 puberty directly as the indirect path via adult BMI is not biologically plausible given that this 36 outcome occurs at an earlier stage in the life course. As such, the direct effect of early life BMI as 37 calculated in the MVMR analysis should be the same as the total effect as derived by univariable 38 estimates. 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60

1 2 3 Supplementary Figure 3: Genetic correlation analysis 4 5 6 7 8 9 10 11 12 Confidential: For Review Only 13 14 15 16 17 Using linkage disequilibrium (LD) score regression, we compared the genetic correlation between 18 19 our two exposures (early life and adult body mass index (BMI)) with measured adult BMI and 20 childhood obesity from two consortia (GIANT and EGG). 21 22 23 24 25 Supplementary Note 1: Simulation for child and adult BMI estimates 26 27 Our measure of early life BMI is based on recalled relative BMI at age 10, reported by 28 29 individuals much later in life. This measure is therefore likely to be subject to 30 misclassification due to individuals misremembering their relative BMI. Such recall bias 31 will not affect our measure of later life BMI which is constructed from measures of height 32 and weight taken at the UK Biobank clinic. We therefore computed a simple simulation 33 34 study to identify what likely effect such misclassification, affecting only one exposure in 35 a two-exposure model, will have on the estimated effects in our multivariable MR 36 estimation. 37 38 We set up our model with two correlated exposures which each have a causal effect on 39 an outcome. Each exposure is modelled to have a true continuous effect on the outcome 40 41 but is only observed to take one of three categories (0/1/2) to reflect the setup of our 42 BMI data. For each exposure a set of 150 SNPs are available which predict the exposures. 43 The model is estimated using a two-sample multivariable MR estimation where the SNP 44 45 exposure associations are estimated in the same sample for both exposures and the SNP 46 outcome association is estimated in a separate sample. 47 48 Within this model we investigated three scenarios; no misclassification in either 49 exposure, misclassification of 15% of the data in exposure 1 and misclassification of 15% 50 of the data and no direct effect on the outcome in exposure one. In all cases exposure 2 is 51 52 also more strongly predicted by the set of SNPs than exposure 1. Details of the variations 53 between the simulations are given in Supplementary Table 1. 54 55 56 57 58 59 60

These results show 22 that there is some bias in the estimated effects, due to the classification of the exposure 23 24 into categories. Misclassification in 푋1 weakens the strength of the instruments for 푋1 25 and increases the bias in the estimated effect, however it does not affect the estimate for 26 푋2. These results also show that when the misclassified exposure has no direct effect on 27 28 the outcome the estimated effect is unbiased. 29 30 31 Supplementary Table 2: Simulation results 32 33 No Misclassification With Misclassification 34 휷ퟏ 0.49 0.49 0 35 36 훽1 0.565 0.651 -0.011 37 Std. error 0.035 0.041 0.035 38 F – statistic 21.27 14.90 14.90 39 휷ퟐ 0.50 0.50 0.50 40 훽2 0.594 0.594 0.601 41 42 Std. error 0.031 0.031 0.026 43 F – statistic 28.31 28.29 28.29 44 N = 50,000. 2000 repetitions.
