Fiche synthèse

1. Objectifs


Intentions :
«We undertook a systematic review of the literature on the association of early childhood low income/SES and physical health in later childhood/adolescence. […] The review seeks to identify the extent to which current literature addresses the following research questions and inform a future research agenda aimed at providing evidence for effective policy and practice interventions to reduce child health inequalities in industrialised countries». (p. 425)

Questions/Hypothèses :
«[1] Does early life exposure to low income/SES have an adverse effect on physical health in later childhood/ adolescence and if so, what is the magnitude of the effect? [2] If an adverse effect is shown, is there evidence of a relationship between duration of early childhood low income/SES (transient v. chronic) and risk of adverse effects on physical health in later childhood/adolescence? [3] If an adverse effect is shown, how does low income/SES interact with other factors, such as parenting and family functioning, in influencing later childhood/adolescent physical health? Have mediators and/or moderators of the relationship been identified?» (p. 425)

Échantillon/Matériau :

3. Résumé


«There is consistent evidence from the review that early life exposure to low income/SES has an adverse effect on physical health in later childhood/adolescence although odds ratios vary by outcome studied and timing and duration of poverty exposure, and not all studies report statistically significant odds ratios at the 5% level. The evidence supports an association but is not proof of causality. Based on the papers identified by our review, the research questions addressing a relationship with duration of poverty in early childhood, and mediation/moderation of the relationship under study, remain unanswered. We found only one study comparing the impact of transitory and chronic low income/SES before the age of 5 years on asthma aged 5–7 years. Although the findings of this study suggest that early childhood exposure to chronic low income/SES carries a higher risk of subsequent asthma, this constitutes only limited evidence of a relationship between duration of early life exposure and later physical health. Belsky et al. reported that parenting mediated some but not all of the effect of low income/SES on parent reported child health status at 6 years of age. No other included study reported on mediation/moderation of the low income/SES and later physical health relationship.» (p. 430)
