Factors influencing obesity among preschoolers: multilevel approach

摘要

Background Childhood obesity is a complex and multifaceted problem involving interactions among child, family and community environment. Aim The purpose of this study was to examine the contributing factors to early childhood obesity within a multilevel context, including child and family, childcare setting and community. Methods A cross‐sectional, quantitative research design was employed. A total of 129 preschoolers and their parents in northwest Florida participated in this study. Child height and weight were measured, and body mass index ( BMI ) was calculated. Parents and directors of preschools completed survey questionnaires to assess child/family, childcare setting and community factors, respectively. Hierarchical multiple regression was used to evaluate the association of each level of factors with child BMI z‐score. Results Twenty‐one per cent of children were overweight or obese (≥85th BMI percentile). In hierarchical multiple regression, household income, parent beliefs, attitudes and practices for child feeding, family obesogenic environment, child routines (screen time on weekends, sleep hours, bedtime) and physical activity environment were significantly related to child BMI z‐score. Conclusions The findings of this study provide a broader understanding of factors that influence child BMI z‐score. Shaping a non‐obesogenic environment by establishing healthy routines for children in the home, childcare setting and community is essential in childhood obesity prevention. Implications for nursing practice and health policy Paediatric nurses should routinely assess accurate parental perception of child weight, feeding style and child routines in well‐child care visits. Healthcare professionals and health policymakers should enact policies that build a healthy environment for preschoolers in their childcare setting and community.
