Deaths registered between 1972 and 1974 in a population of 260 000 in a rural area of Bangladesh were analysed for seasonal patterns. Age and cause of death groups were considered. The findings include: (1) The number of neonatal deaths has a peak in October but after adjustment for the seasonal pattern of births, the actual risk of neonatal morality is found to peak 2 months earlier. (2) Postneonatal deaths peak in April with above average proportions of deaths in the peak month attributed to dysentery. (3) Deaths of persons above age 45 peak in the cool season. (4) Dysentery and chronic diarrhoea deaths are highest in December. This coincides with the maximum incidence of shigella dysentery. (5) Accidental deaths are maximum in July due to increased drownings during the monsoon. The age and cause of death groups which contribute the largest proportions of total deaths are also the groups which show seasonal patterns.
对1972年至1974年期间孟加拉国农村地区26万人口中登记的死亡情况进行了季节性模式分析。考虑了年龄和死亡原因分组。研究结果包括：（1）新生儿死亡人数在10月达到峰值，但在对出生的季节性模式进行调整后，发现新生儿死亡的实际风险在早两个月时达到峰值。（2）新生儿期后死亡在4月达到峰值，峰值月份中因痢疾导致的死亡比例高于平均水平。（3）45岁以上人群的死亡在凉爽季节达到峰值。（4）痢疾和慢性腹泻死亡在12月最高。这与志贺氏菌痢疾的最高发病率相吻合。（5）意外死亡在7月最多，原因是季风期间溺水事件增加。占总死亡人数比例最大的年龄和死亡原因分组也是呈现季节性模式的分组。
