1. Objectifs

Intentions :
«Framed within this lifecourse perspective, we examined how concurrent poverty, prior poverty occurring at specific times, and cumulative poverty across time may lead to differential patterns of health in a birth cohort of children during the first four years of life.» (p. 3)

2. Méthode

Échantillon/Matériau :
«We used data from the Québec Longitudinal Study of Child Development (QLSCD), an ongoing population based birth cohort study coordinated by the Institut de la Statistique du Québec (ISQ) (Québec Institute of Statistics). The QLSCD started with a representative sample of 2 120 singleton infants who were recorded in the registry of Quebec births in 1997/1998.» (p. 3)

Instruments :

3. Résumé

À la lumière de leurs recherches, les auteurs constatent que «results suggest that different dynamics of poverty contribute to the observed negative health outcomes among children living in poverty […]. Perceived health status at 5 months was more likely to be less than very good among chronically poor children compared to never-poor children. For both outcomes, the magnitude of the difference between the never poor and the chronically poor children tend to decline over time.» (p. 9-10) «The results showed that on average, experience of ill health among QLSCD children varied across time. Taking into account children’s sex and birth order, maternal age, education and immigration status, day-care utilization, single parenthood, and birth order variability, the number of mother-reported asthma-like attacks decreased over time. […] Irrespective of other covariates, insufficient income reported during the previous survey round was significantly associated with the number of mother-reported asthma-like attacks. This influence remained statistically significant even after controlling for concurrent poverty status.» (p. 10)
