The association between meteorologic temperature and sudden infant death syndrome was investigated in the 1982-1983 North Carolina birth cohort. Maximum daily temperatures recorded at weather stations in the subject's county of residence for each day of the first year of life were entered into hazards models as time-dependent covariates. Risk ratios for a maximum temperature of < or = 53 degrees F (12 degrees C) 5 days before the event compared with a maximum temperature of > 53 degrees F were 2.3 (95% confidence interval 1.6-3.3) for blacks and 1.5(95% confidence interval 1.0-2.1) for whites. Similar results were found for minimum daily temperature. The analysis controlled for season of birth, sex, maternal age, maternal education, parity, and birth weight.
在1982 - 1983年北卡罗来纳州出生队列中，对气象温度与婴儿猝死综合征之间的关联进行了调查。将婴儿出生后第一年每一天在其居住县气象站记录的每日最高温度作为随时间变化的协变量纳入风险模型。与最高温度>53华氏度（12摄氏度）相比，事件发生前5天最高温度≤53华氏度（12摄氏度）时，黑人的风险比为2.3（95%置信区间1.6 - 3.3），白人为1.5（95%置信区间1.0 - 2.1）。对于每日最低温度也发现了类似结果。该分析对出生季节、性别、母亲年龄、母亲教育程度、产次和出生体重进行了控制。
