1. Objectifs
Intentions :
The goal of this study is «to (1) identify longitudinal trajectories of food insecurity during childhood and the sociodemographic characteristics associated with these trajectories and (2) examine the associations of the trajectories with a range of mental health and social functioning outcomes during adolescence.» (p. 2)
2. Méthode
Échantillon/Matériau :
«We used information on household characteristics reported by both parents at 5 months and 2.5 years of age (1998 and 2000, respectively), food insecurity reported by mothers from 1.5 to 13 years of age (1999-2011), and mental health and functioning outcomes reported by adolescents at 15 years of age (2013).» (p. 3) «Of 2120 participants at inception of the study, 1288 (60.8%) provided information on food insecurity on at least 4 of the 6 assessments and 2032 (95.8%; 1026 [50.5%] male) provided information on food insecurity on at least 1 occasion and were included in this analysis […].» (p. 4)

3. Résumé
«In this population-based cohort study from Québec, Canada, we found that 3.6% of children had stable, high risk for recurrent food insecurity, whereas 96.4% of children had consistently low risk over time. Characteristics at birth, including household income insufficiency, greater number of siblings, and poorer parental mental health, were associated with the high-risk trajectory of food insecurity. High risk for food insecurity during childhood was associated with higher levels of cannabis use, peer bullying, and school dropout potential at 15 years of age. These associations were present for both continuous and dichotomized (severe) outcome levels, and they were robust to adjustment for income insufficiency and parental mental health. In the general population of Québec, Canada, from 2011 to 2012, the prevalence of household food insecurity was 8%, and large households, single-parent households, lower income level, and lower educational attainment were associated with greater risk of food insecurity.» (p. 7)
