针对气温（Ta）与出生结局的研究较为少见。
我们利用传统气温监测站数据以及模拟地址数据，对美国马萨诸塞州不同孕期暴露阶段的出生结局与每日气温之间的关联展开了调查。
我们运用传统气温监测站数据以及模拟地址气温数据，对美国马萨诸塞州不同孕期暴露阶段的出生结局和日均气温进行了评估。我们采用线性和逻辑混合模型以及加速失效时间模型，来估算气温与孕龄超过22周的活产儿以下出生结局之间的关联：足月出生体重（≥37周）、低出生体重（LBW；足月时体重<2500克）、胎龄以及早产（PT；<37周）。模型针对个体层面的社会经济状况、交通密度、空气动力学当量直径≤2.5微米的颗粒物（PM2.5）、普查区域的随机截距以及母亲健康状况进行了校正。
出生前多个时间段的预测气温与出生体重呈负相关：孕晚期气温每升高一个四分位数间距（8.4°C），平均出生体重就会降低16.7克（95%置信区间：–29.7，–3.7）。整个孕期的气温与早产[比值比（OR）=1.02；95%置信区间：1.00，1.05]和低出生体重（OR = 1.04；95%置信区间：0.96，1.13）呈正相关。
在我们的研究人群中，孕期气温与较低的出生体重和较短的胎龄相关。

Studies looking at air temperature (Ta) and birth outcomes are rare. We investigated the association between birth outcomes and daily Ta during various prenatal exposure periods in Massachusetts (USA) using both traditional Ta stations and modeled addresses. We evaluated birth outcomes and average daily Ta during various prenatal exposure periods in Massachusetts (USA) using both traditional Ta stations and modeled address Ta. We used linear and logistic mixed models and accelerated failure time models to estimate associations between Ta and the following outcomes among live births > 22 weeks: term birth weight (≥ 37 weeks), low birth weight (LBW; < 2,500 g at term), gestational age, and preterm delivery (PT; < 37 weeks). Models were adjusted for individual-level socioeconomic status, traffic density, particulate matter ≤ 2.5 μm (PM2.5), random intercept for census tract, and mother’s health. Predicted Ta during multiple time windows before birth was negatively associated with birth weight: Average birth weight was 16.7 g lower (95% CI: –29.7, –3.7) in association with an interquartile range increase (8.4°C) in Ta during the last trimester. Ta over the entire pregnancy was positively associated with PT [odds ratio (OR) = 1.02; 95% CI: 1.00, 1.05] and LBW (OR = 1.04; 95% CI: 0.96, 1.13). Ta during pregnancy was associated with lower birth weight and shorter gestational age in our study population. Kloog I, Melly SJ, Coull BA, Nordio F, Schwartz JD. 2015.
