【 摘 要 】

The objective of this dissertation was to examine the association between sibship composition and child weight status, and to investigate maternal feeding behavior, child eating behavior, and sibling interactions during mealtimes as pathways underlying this association. Three analytic samples (N=273, N=274, and N=75) were selected from an initial cohort of 301 mother-child dyads recruited from Head Start facilities in South-Central Michigan. Participants completed questionnaires, anthropometry, a videotaped laboratory mealtime observation, and 3 videotaped family mealtime observations at home. Multiple logistic regression was used to examine the association of birth order and number and sex of siblings with odds of overweight or obesity. Path analysis was used to examine maternal feeding and child eating behavior as mediators in the association of birth order with child overweight or obesity. Sibling interactions during mealtimes were coded from the family mealtime observation videos, and path analysis was used to examine encouragements to eat received by the index child (IC) from the sibling as a mediator in the association of birth order and sex of sibling with child body mass index z-score (BMIz). Among the analytic sample of 273, only children and youngest siblings had higher odds of overweight or obesity compared to oldest siblings. Having younger siblings and having a brother were associated with lower odds. Among the analytic sample of 274, the association between only child status and greater likelihood of overweight or obesity was fully mediated by higher maternal discouragement to eat and lower maternal praise. The association between youngest sibling status and greater likelihood of overweight or obesity was partially mediated by lower maternal praise and lower child food fussiness. Among the analytic sample of 75, being the younger sibling in a sibling dyad was associated with the IC receiving more encouragements to eat from the sibling. However, the IC having a sister compared with a brother was not associated with receiving more encouragements to eat from the sibling. The IC receiving more encouragements to eat from the sibling was associated with lower IC BMIz. Findings can help inform family-based obesity programs by guiding recommendations for family mealtime interactions.
