There is evidence that the worldwide prevalence of asthma is increasing, particularly in children.
To compare the cumulative prevalence of medical diagnosis of asthma among Mexican schoolchildren in two surveys 12 years apart.
The study populations of the two comparable cross sectional surveys comprise six to twelve years old public and private schoolchildren in Villahermosa, Tabasco, Mexico. Sample sizes in 1986 and 1998 were 6,465 and 6,073 children and response rates were 72 and 85%, respectively. The sampling frame and sampling method were identical in both surveys. The prevalence of medical diagnosis was expressed by sex and age comparing 1986 to 1998. An analysis of contingency tables was used to asses the differences in the prevalence rates.
Cumulative prevalence of medical diagnosis of asthma in 1986 and 1998 were 8.74 and 12.63%, respectively, 45% of increase. We found a significant increase in lifetime of asthma (p = 0.001). The observed increases were independent of sex and age.
As it has come to pass all over, our results support a significant increase in the cumulative prevalence in the last 12 years among schoolchildren in Villahemosa, Tabasco, Mexico.
有证据表明，全球哮喘患病率正在上升，尤其是在儿童中。
比较相隔12年的两项调查中墨西哥学童哮喘医学诊断的累积患病率。
两项可比横断面调查的研究人群包括墨西哥塔巴斯科州比亚埃尔莫萨市6至12岁的公立和私立学童。1986年和1998年的样本量分别为6465名和6073名儿童，应答率分别为72%和85%。两项调查的抽样框架和抽样方法相同。通过比较1986年和1998年按性别和年龄划分的医学诊断患病率。使用列联表分析来评估患病率的差异。
1986年和1998年哮喘医学诊断的累积患病率分别为8.74%和12.63%，增长了45%。我们发现哮喘终生患病率显著增加（p = 0.001）。观察到的增加与性别和年龄无关。
正如世界各地所发生的那样，我们的结果支持在过去12年中墨西哥塔巴斯科州比亚埃尔莫萨市学童的累积患病率显著增加。
