Downloaded from 4 5 6 7 Objective: To determine the incidence and risk factors for hypothermia among 8 neonates in Lira district, Northern Uganda. 9 10 Setting: Three sub counties of Lira district in Northern Uganda 11 12 Design: This was a community-based prospective cohort study nested in a cluster 13 14 randomized controlled trial. 15 Participants: Mother – baby pairs enrolled in a cluster randomised controlled trial, 16 designed to promote health facility births and newborn care practices, in Lira district, 17 Northern Uganda. An axillary temperature was taken during a home visit using a 18 lithium battery-operatedFor peerdigital thermometer review only 19 20 21 Primary and secondary outcomes: The primary outcome measure was the incidence 22 of hypothermia. The secondary outcome measures were socioeconomic, 23 environmental, birth and newborn related factors associated with moderate to severe 24 hypothermia determined using a generalized estimating equation model for the 25 Poisson family, with a log link, taking clustering into account, and assuming an 26 exchangeable correlation. 27 28 29 Results: We recruited 1527 participants. Of these, 1330 had a temperature taken 30 within the first 3 days of life. The incidence of hypothermia (temperature less than 31 36.5°C) was 678/1330 [51.0%: 95% CI (46.9-55.1)]. Of these, 32% (429/1330), 32 95%CI (29.5-35.2)] had mild hypothermia (temperature 36.0°C - <36.5°C), whereas 33 18.7% (249/1330), 95% CI (15.8-22.0) had moderate hypothermia (temperature 34 32.0°C - <36.0°C). None had severe hypothermia (temperature less than 32.0°C). At 35 multivariable analysis, the factors associated with neonatal hypothermia included: 36 home birth [Adjusted Risk Ratio, ARR, 1.9, 95% CI (1.4-2.6)]; low birth weight 37 http://bmjopen.bmj.com/ 38 [ARR 1.7, 95%CI (1.3-2.3)]; and delayed breastfeeding initiation [ARR 1.2, 95%CI 39 (1.0-1.5]. 40 41 Conclusion: The incidence of neonatal hypothermia was very high, demonstrating 42 that communities in tropical climates should not ignore neonatal hypothermia. 43 44 Interventions designed to address neonatal hypothermia should consider ways of 45 reaching newborns born at home, as those with low birth weight are at greater risk of on September 29, 2021 by guest.
