研究高温环境对婴儿喂养方式和儿童保育的影响。前瞻性队列研究定量数据的二次分析。在布基纳法索波波-迪乌拉索社区进行的访谈。纯母乳喂养在布基纳法索并不普遍。在12个月的时间里，对866名妇女（城市：农村比例为1：1）进行了访谈。参与者在三个时间点接受采访：队列进入（在妊娠20周和产后22周之间），3个月和9个月后。9个月随访时的保留率为90%。我们的二次分析集中在产后妇女（n=857）。波波-迪乌拉索一个气象站测得的日平均温度（℃）。气象数据来自公开档案（TuTiempo.net）。自我报告的母乳喂养时间（分钟/天），6个月以下婴儿的纯母乳喂养（过去24小时内没有提供母乳以外的液体），6-12个月婴儿的补充喂养（过去24小时内提供母乳以外的任何液体），照顾儿童的时间（分钟/天）。当地居民全年都处于高温状态（日平均温度范围为22.6°C-33.7°C）。同一天平均温度每升高1°C，母乳喂养减少2.3分钟/天（95% CI -4.6至0.04，p=0.05），儿童保育增加0.6分钟/天（0.06至1.2，p=0.03）。温度与婴儿年龄相互作用，影响母乳喂养持续时间（p=0.02），温度和母乳喂养之间的关联更强（负）婴儿年龄（0-57周）。随着温度的升高，纯母乳喂养极年幼婴儿（0-3个月）的几率趋于降低（OR=0.88，0.75至1.02，p=0.09）。温度与3-6个月纯母乳喂养或补充喂养（6-12个月）之间没有关联。与一年中最凉爽的时候相比，妇女在最热的时候母乳喂养的时间要少得多（约25分钟/天）。气候变化健康适应计划应包括在高温期间向哺乳母亲提供建议。
To examine the effects of high ambient temperature on infant feeding practices and childcare. Secondary analysis of quantitative data from a prospective cohort study. Community-based interviews in the commune of Bobo-Dioulasso, Burkina Faso. Exclusive breastfeeding is not widely practised in Burkina Faso. 866 women (1:1 urban:rural) were interviewed over 12 months. Participants were interviewed at three time points: cohort entry (when between 20 weeks’ gestation and 22 weeks’ postpartum), three and nine months thereafter. Retention at nine-month follow-up was 90%. Our secondary analysis focused on postpartum women (n=857). Daily mean temperature (°C) measured at one weather station in Bobo-Dioulasso. Meteorological data were obtained from publicly available archives (TuTiempo.net). Self-reported time spent breastfeeding (minutes/day), exclusive breastfeeding of infants under 6 months (no fluids other than breast milk provided in past 24 hours), supplementary feeding of infants aged 6–12 months (any fluid other than breast milk provided in past 24 hours), time spent caring for children (minutes/day). The population experienced year-round high temperatures (daily mean temperature range=22.6°C–33.7°C). Breastfeeding decreased by 2.3 minutes/day (95% CI -4.6 to 0.04, p=0.05), and childcare increased by 0.6 minutes/day (0.06 to 1.2, p=0.03), per 1°C increase in same-day mean temperature. Temperature interacted with infant age to affect breastfeeding duration (p=0.02), with a stronger (negative) association between temperature and breastfeeding as infants aged (0–57 weeks). Odds of exclusive breastfeeding very young infants (0–3 months) tended to decrease as temperature increased (OR=0.88, 0.75 to 1.02, p=0.09). There was no association between temperature and exclusive breastfeeding at 3–6 months or supplementary feeding (6–12 months). Women spent considerably less time breastfeeding (~25 minutes/day) during the hottest, compared with coolest, times of the year. Climate change adaptation plans for health should include advice to breastfeeding mothers during periods of high temperature.
