Monthly trends in deaths attributed to asthma in the 5-34 year age group were examined for England and Wales over the period 1960-82. Deaths were most frequent in the third quarter (July to September) and peaked in August. Analysis of the 1970-82 period showed that this variation was present in the three constituent age groups 5-14, 15-24, and 25-34 but was most pronounced in the 5-14 year olds.
对1960年至1982年期间英格兰和威尔士5至34岁年龄组中归因于哮喘的死亡月度趋势进行了研究。死亡在第三季度(7月至9月)最为频繁,且在8月达到峰值。对1970年至1982年期间的分析表明,这种变化在5至14岁、15至24岁和25至34岁这三个组成年龄组中都存在,但在5至14岁年龄组中最为明显。
