To examine and identify relations between sudden infant death syndrome (SIDS) and wind, particularly the föhn wind, in Christchurch, New Zealand.
A retrospective epidemiological study combining details of regional hourly meteorological variables and reported SIDS cases.
Christchurch, New Zealand, between 1968 and 1997 inclusively.
All 646 infants reported as dying from SIDS within the greater Christchurch region.
Analysis of 1968-1989 data revealed nine wind variables significantly related to SIDS. When compared with corresponding variables calculated over the 1990-1997 period, only the northerly wind on the day of death and the southerly wind three days before a SIDS death had estimated associations with similar effect size and sign. However, both these variables had confidence intervals that included unity.
No evidence was found to suspect that föhn winds influenced SIDS occurrence. The relations identified between SIDS incidence and wind, after controlling for the effects of temperature and trend, were tenuous and relatively small. More data are necessary to substantiate whether northerly winds on the day of death or southerly winds occurring three days before a death are truly associated with SIDS. It seems that wind has little, if any effect on SIDS incidence in Christchurch.
研究并确定新西兰克赖斯特彻奇市婴儿猝死综合征（SIDS）与风，尤其是焚风之间的关系。
一项回顾性流行病学研究，结合区域每小时气象变量的详细信息和报告的婴儿猝死综合征病例。
新西兰克赖斯特彻奇市，时间跨度为1968年至1997年（含）。
大克赖斯特彻奇地区所有报告死于婴儿猝死综合征的646名婴儿。
对1968 - 1989年数据的分析显示，有9个风变量与婴儿猝死综合征显著相关。与1990 - 1997年期间计算的相应变量相比，只有死亡当天的北风和婴儿猝死综合征死亡前三天的南风，其估计关联具有相似的效应大小和符号。然而，这两个变量的置信区间都包含1。
没有证据怀疑焚风会影响婴儿猝死综合征的发生。在控制了温度和趋势的影响后，确定的婴儿猝死综合征发病率与风之间的关系微弱且相对较小。需要更多数据来证实死亡当天的北风或死亡前三天出现的南风是否真的与婴儿猝死综合征有关。在克赖斯特彻奇，风似乎对婴儿猝死综合征发病率几乎没有影响（如果有影响的话也很小）。
