To examine and identify relationships between the sudden infant death syndrome (SIDS) and environmental temperature in Canterbury, New Zealand.
A retrospective epidemiological study combining details of regional hourly temperature and reported SIDS cases.
Canterbury, New Zealand, between 1968 and 1989 inclusively.
All infants reported as dying from SIDS within the Canterbury region.
The SIDS incidence increased after months with prolonged colder minimum temperatures, confirming the seasonality of SIDS. After adjusting for this seasonality, days that showed little change in hourly temperature and days with warmer minimum temperatures recorded were seen to have a significantly increased the incidence of SIDS. No evidence was found for other relationships between the SIDS incidence and various measures of daily temperatures on the day of death, over the preceding eight days or between these days. Infants aged 12 weeks and over were more susceptible to SIDS on days when small hourly temperature changes were recorded than their younger counterparts; no other age differences emerged.
This study confirmed that the incidence of SIDS is affected by seasonality and temperature on the day of death. In particular, after a prolonged period of cold minimum temperatures, infants were most at risk from SIDS on days on which either a warmer minimum temperature or little hourly variation in temperature were recorded. No other daily or lagged daily temperature factor (lagged up to eight days before the day of death) was statistically associated with the SIDS incidence. It is suspected that the inconsistent previously published lag effect findings actually describe some other phenomenon such as parental behaviour or infant thermoregulation.
研究并确定新西兰坎特伯雷地区婴儿猝死综合征（SIDS）与环境温度之间的关系。
一项回顾性流行病学研究，结合了区域每小时温度细节和报告的婴儿猝死综合征病例。
新西兰坎特伯雷地区，时间跨度为1968年至1989年（含）。
坎特伯雷地区所有报告死于婴儿猝死综合征的婴儿。
在最低气温持续较低的月份之后，婴儿猝死综合征发病率上升，证实了婴儿猝死综合征的季节性。在对这种季节性进行调整后，发现每小时温度变化不大的日子以及记录到最低气温较高的日子，婴儿猝死综合征发病率显著增加。未发现婴儿猝死综合征发病率与死亡当天、前八天或这些日子之间的各种每日温度测量值之间存在其他关系。与年龄较小的婴儿相比，12周及以上的婴儿在记录到每小时温度变化较小的日子更容易患婴儿猝死综合征；未出现其他年龄差异。
本研究证实，婴儿猝死综合征的发病率受季节性和死亡当天温度的影响。特别是，在最低气温长期寒冷之后，在记录到最低气温较高或每小时温度变化较小的日子里，婴儿患婴儿猝死综合征的风险最高。没有其他每日或滞后每日温度因素（在死亡当天前最多滞后八天）与婴儿猝死综合征发病率存在统计学关联。怀疑之前发表的不一致的滞后效应研究结果实际上描述的是其他一些现象，如父母行为或婴儿体温调节。
