对英格兰和威尔士死胎率和1岁以下死亡率的季节性变化进行了研究，以检查多年来季节性变化的变化以及季节性变化率和季节性温度之间的相关性。研究了1928-1978年期间的死胎率和1912-1978年期间6个不同年龄组的1岁以下死亡率。死亡率的季节性变化（季节性变化）消失发生在. apprx。1950年，新生儿死亡率为. apprx。1965.对于1-2个月时的死亡。自1955年以来，季节性下降的趋势很明显，但3-11个月的死亡率没有这种趋势。年龄。在淡季之前的一段时间，并为第一季度的一年，有一个高的负相关性之间的新生儿死亡率和平均温度在英格兰和威尔士，但这种相关性下降的季节性变化率下降。新生儿死亡率的季节变化显然与1921-1960年期间的冬季气温密切相关。对于1-11个月时的死亡。在2000年至2001年期间，温度与死亡率的季节变化之间过去和现在都有关系，但这种关系不如新生儿死亡率密切。
Seasonal variation in the rates of stillbirth and of deaths under the age of 1 yr were studied for England and Wales to examine changes in the seasonal variation over the years and the correlation between seasonal rates and seasonal temperatures. The quarterly rates of stillbirths were studied for the period 1928-1978 and of deaths under the age of 1 yr, in 6 different age groups, for the period 1912-1978. A disappearance of seasonal variation in rates (deseasonality) occurred for stillbirths in .apprx. 1950, and for neonatal deaths in .apprx. 1965. For deaths at 1-2 mo. a trend towards deseasonality was apparent since 1955, but there was no such trend for deaths at 3-11 mo. of age. In the period before deseasonality, and for the 1st quarter of the year, there was a high negative correlation between the neonatal death rate and the mean temperature in England and Wales but this correlation fell as the seasonal variation in rates fell. Seasonal variation in the neonatal death rate apparently was closely related to winter temperatures during the period 1921-1960. For deaths at 1-11 mo. old, there was and still is a relation between temperature and seasonal variation in rates, but the relation was less close than for the neonatal death rate.
