This article describes trends in the prevalence of asthma among children aged 0 to 14 from 1978/79 to 1994/95, and in hospital separations for asthma from 1974/75 to 1994/95. It also examines factors associated with childhood asthma.
Information on asthma among children aged 0 to 11 is from the 1994/95 National Longitudinal Survey of Children and Youth (NLSCY), and among children aged 12 to 14, from the 1994/95 National Population Health Survey (NPHS). Hospital separation data are from the Hospital Morbidity File. Mortality data are from the Canadian Vital Statistics Data Base.
Prevalence estimates of asthma were calculated based on a sample of 22,831 children aged 0 to 11 from the NLSCY and 637 children aged 12 to 14 from the NPHS. Logistic regression was used to estimate the odds of asthma among children aged 0 to 11 by selected characteristics.
The prevalence of childhood asthma and hospital separations rates for asthma have increased sharply. A history of bronchitis and allergies, parental asthma, and residence in the Atlantic provinces and Quebec are associated with higher rates of asthma in children.
本文描述了1978/79年至1994/95年0至14岁儿童哮喘患病率的趋势，以及1974/75年至1994/95年因哮喘住院的情况。还研究了与儿童哮喘相关的因素。
0至11岁儿童哮喘的信息来自1994/95年全国儿童和青少年纵向调查（NLSCY），12至14岁儿童的信息来自1994/95年全国人口健康调查（NPHS）。住院数据来自医院发病率文件。死亡率数据来自加拿大生命统计数据库。
基于NLSCY中22,831名0至11岁儿童和NPHS中637名12至14岁儿童的样本计算哮喘患病率估计值。采用逻辑回归按选定特征估计0至11岁儿童患哮喘的几率。
儿童哮喘患病率和哮喘住院率急剧上升。支气管炎和过敏史、父母患哮喘以及居住在大西洋省份和魁北克与儿童哮喘发病率较高有关。
