摘要

BACKGROUND—The aim of the present study was to compare the prevalence of asthma among schoolchildren in 1978, 1991, and 1998 in Patras, Greece.
METHODS—The study populations of the three comparable cross sectional surveys comprised third and fourth grade public school children in Patras, Greece. Sample sizes in 1978, 1991, and 1998 were 3735,2952 and 3397 children and response rates were 80.4%, 81.9%, and 90.6%, respectively. Prevalence of current, non-current, and lifetime asthma or recurrent wheezing was determined by parental questionnaire. Personal communication with the parents of asthmatic children in 1991 and 1998 provided data on lost schooldays.
RESULTS—Prevalence rates of current asthma or wheezing in 1978, 1991, and 1998 were 1.5%, 4.6%, and 6.0%, respectively (1978-91: p=0.01, 1991-98: p=0.02, 1978-98: p=0.03). Lifetime prevalences of asthma or wheezing in 1991 and 1998 were 8.0% and 9.6%, respectively (p=0.03). Current diagnosed asthma increased proportionally to diagnosed wheezing during 1991-98. The number of schooldays lost in the previous 2 years because of asthma did not change (p>0.1) between 1991 (0.31 per child) and 1998 (0.34 per child).
CONCLUSIONS—Our results support a true increase in the prevalence of current andlifetime asthma in the last 20 years among pre-adolescent children inPatras, Greece.

方法—三个可比较的横断面调查的研究人群分别为三年级和四年级希腊帕特雷的公立学校儿童。 1978年,1991年和1998年的样本量为3735,2952名儿童和3397名儿童,应答率分别为80.4%,81.9%和90.6%。通过父母问卷调查确定当前,非当前和终生哮喘或反复喘息的患病率。 1991年和1998年与哮喘儿童父母的私人交流提供了失学日的数据。
结果-1978年,1991年和1998年当前哮喘或喘息的患病率分别为1.5%,4.6%和6.0%。 (1978-91:p = 0.01,1991-98:p = 0.02,1978-98:p = 0.03)。 1991年和1998年,哮喘或喘息的终生患病率分别为8.0%和9.6%(p = 0.03)。在1991-98年间,当前诊断出的哮喘与诊断出的喘息成比例增加。在1991年(每个孩子0.31个)和1998年(每个孩子0.34个)之间,过去两年因哮喘而失去的上学日数没有变化(p> 0.1)。
结论—我们的结果支持当前和在过去20年中,美国青春期前儿童的终生哮喘希腊帕特雷。
