• Description:
  Background
  
  Children exposed to multiple stressors are more likely to be overweight, but little is known about the mechanisms explaining this association.
  
  Purpose
  
  This cross-sectional study examined whether children exposed to multiple stressors had higher waist circumference, and whether this association was mediated through children’s television time.
  
  Methods
  
  Participants were 319 parent-child dyads. Children were 2–5 years old and had at least one overweight parent (BMI ≥ 25 kg/m2). Data were collected at baseline of a larger childhood obesity prevention study and included information on psychosocial stressors (e.g., parenting stress), demographic stressors (e.g., low income), children’s television time, and children’s waist circumference. Two cumulative risk scores were created by summing stressors in each domain (demographic and psychosocial). Mediation and moderated mediation analyses were conducted.
  
  Results
  
  Indirect effects of both cumulative risk scores on waist circumference through television time were not significant; however, moderated mediation analyses found significant moderation by gender. The indirect effects of both risk scores on waist circumference through television time were significant and positive for girls, but near-zero for boys.
  
  Conclusions
  
  Reducing television time should be explored as a strategy for buffering against the negative health effects of exposure to multiple stressors among girls. Longitudinal and intervention research is needed to confirm these results, and to identify mediating factors between cumulative risk and body weight among boys.
