Fiche synthèse

1. Objectifs


Intentions :
«The main objectives of this thesis were to examine the adjusted associations between the place factors: material deprivation, social deprivation, social cohesion, disorder, and living location, with change in child BMI Z-score and with change in family food insecurity status in a Canadian cohort of children.» (p. ii) Cette thèse compte cinq articles. Les deux premiers sont relatifs à la revue de la littérature, tandis que les trois autres présentent les résultats. «The objective of [the third article] was to determine the influence of place factors on weight gain in a contemporary cohort of children while also adjusting for early life and individual/family social factors.» (p. 169) The objective of the fourth article is «[t]o determine the association between local environmental factors with child weight status in a longitudinal study […].» (p. 188) Finally the objective of the last article «was to determine if time-dependent measures of social cohesion, disorder, and living location were associated with changes in the odds of household food insecurity, while also adjusting for area material and social deprivation.» (p. 220)

2. Méthode


Échantillon/Matériau :
«The Québec Longitudinal Study of Child Development was used to meet the main objectives of this thesis. Response data from six collection cycles (4 – 10 years of age) were used in three main analyses.» (p. ii) À noter que l’échantillon est le même pour les trois articles.

Instruments :
Questionnaire

Type de traitement des données :
Analyse statistique

3. Résumé


«Social deprivation, social cohesion and disorder were strongly and positively associated with family food insecurity, increasing the odds by 45-76%. These place factors, on the other hand, were not consistently associated with child weight status. Material deprivation was not important for either outcome, except for a slight positive association in the mixed models analysis of child weight status. Living location was not important in explaining family food insecurity. On the other hand, it was associated with child weight status in both analyses, but the nature of the relationship is still unclear. […] Results do not suggest that addressing similar place factors may alleviate both child excess weight and family food insecurity. More high quality longitudinal and experimental studies are needed to clarify relationships between the local environment and child weight status and family food insecurity. » (p. ii-iii)
