To examine the relation between low income and child psychosocial morbidity cross-sectionally and longitudinally.
Cross-sectional survey with follow-up.
Ontario.
Children aged 4 to 16 years from families selected by means of stratified, clustered and random sampling of 1981 Canada Census data. Results were based on the responses of 2503 children interviewed in 1983 and 1076 re-interviewed in 1987.
Prevalence rates of psychiatric disorders, poor school performance and social impairment.
There was a significant relation between low income and psychosocial morbidity, with a threshold at an income level of less than $10,000. Poor children 4 to 11 years of age were at greater risk of morbidity than poor children 12 to 16, but there were no significant age differences. Logistic regression revealed that low income and noneconomic factors (low maternal education and family dysfunction) shared significant independent influences on the prevalence of psychosocial morbidity.
Low income is strongly associated with psychosocial morbidity in children. Both economic and noneconomic factors showed independent influences on morbidity. These findings have important clinical, scientific and policy implications.
横断面及纵向研究低收入与儿童心理社会疾病之间的关系。
有随访的横断面调查。
安大略省。
根据1981年加拿大人口普查数据，通过分层、整群和随机抽样选取家庭中的4至16岁儿童。结果基于1983年接受访谈的2503名儿童以及1987年再次接受访谈的1076名儿童的回答。
精神障碍患病率、学业成绩差和社会功能受损情况。
低收入与心理社会疾病之间存在显著关系，收入水平低于10,000美元为临界值。4至11岁的贫困儿童比12至16岁的贫困儿童患病风险更高，但年龄差异无统计学意义。逻辑回归显示，低收入和非经济因素（母亲教育程度低和家庭功能失调）对心理社会疾病患病率具有显著的独立影响。
低收入与儿童心理社会疾病密切相关。经济和非经济因素均对疾病有独立影响。这些发现具有重要的临床、科学和政策意义。
