Abstract：
It remains unclear whether and how maternal exposure to biomass fuel influences infant anthropometry or body proportionality at birth, which are linked to their survival, physical growth, and neurodevelopment. Therefore, this study seeks to explore the association between household-level exposure to biomass cooking fuels and infant size and body proportionality at birth among women in rural Bangladesh. A total of 909 women were derived from the Pregnancy Weight Gain study, which was conducted in Matlab, a rural area of Bangladesh. Infant\'s weight (g), length (cm), head circumference (cm), small for gestational age (SGAW), short for gestational age (SGAL), low head circumference for gestational age (SGAHC), ponderal index, and cephalization index at birth were the outcomes studied. Of the women, 721 (79.3%) were dependent on biomass fuel. Compared to infants born to mothers who used gas for cooking, those born to biomass users had lower weight (β - 94.3, CI - 155.9, - 32.6), length (β - 0.36, 95% CI - 0.68, - 0.04), head circumference (β - 0.24, CI - 0.47, - 0.02) and higher cephalization index (β 0.03, CI 0.01, 0.05) at birth. Maternal biomass exposure is more likely to lead to symmetric SGA, although there is evidence for some brain-sparing effects.
摘要：
目前尚不清楚母亲接触生物质燃料是否以及如何影响婴儿出生时的人体测量学或身体比例，这与他们的生存有关，身体生长，和神经发育。因此,本研究旨在探讨家庭水平的生物质烹饪燃料暴露与孟加拉国农村女性出生时婴儿体型和身体比例之间的关系.共有909名妇女来自妊娠增重研究，这是在Matlab中进行的，孟加拉国的一个农村地区。婴儿体重（g），长度(cm),头围(cm),小于胎龄（SGAW），胎龄短（SGAL），低头围胎龄（SGAHC），黄体指数，和出生时的头化指数是研究的结果。在女性中，721（79.3％）依赖生物质燃料。与使用燃气做饭的母亲所生的婴儿相比，生物量使用者出生的人体重较低(β-94.3，CI-155.9，-32.6)，长度（β-0.36，95%CI-0.68，-0.04），出生时头围（β-0.24，CI-0.47，-0.02）和较高的头化指数（β0.03，CI0.01，0.05）。母体生物量暴露更有可能导致对称SGA，尽管有证据表明有一些节省大脑的作用。
