El. Lipman et al., RELATION BETWEEN ECONOMIC DISADVANTAGE AND PSYCHOSOCIAL MORBIDITY IN CHILDREN, CMAJ. Canadian Medical Association journal, 151(4), 1994, pp. 431-437
Objective: To examine the relation between low income and child psycho
social morbidity cross-sectionally and longitudinally. Design: Cross-s
ectional survey with follow-up. Setting: Ontario. Participants: Childr
en aged 4 to 16 years from families selected by means of stratified, c
lustered and random sampling of 1981 Canada Census data. Results were
based on the responses of 2503 children interviewed in 1983 and 1076 r
e-interviewed in 1987. Outcome measures: Prevalence rates of psychiatr
ic disorders, poor school performance and i social impairment. Results
: 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 t
han poor children 12 to 16, but there were no significant age differen
ces. Logistic regression revealed that low income and noneconomic fact
ors (low maternal education and family dysfunction) shared significant
independent influences on the prevalence of psychosocial morbidity. C
onclusions: Low income is strongly associated with psychosocial morbid
ity in children. Both economic and noneconomic factors showed independ
ent influences on morbidity. These findings have important clinical, s
cientific and policy implications.
