BACKGROUND: Infancy is a critical period for obesity prevention. Emerging evidence links household chaos to poor health outcomes, yet its impact on obesity in infancy is unknown.
OBJECTIVES: We examined associations between household chaos when infants were 6 and 12 months and weight-for-length (WFL) z-score at 12 months, exploring potential mediation by infant sleep and screen time.
METHODS: We examined 401 predominately Black women and infants in the southeastern United States. We conducted multivariable linear regressions examining household chaos and infant WFL z-score, assessing breastfeeding, sleep, screen time as potential mediators.
RESULTS: Among infants, 69.7% were Black and 49.0% were female. Mean breasting duration was 3.7 months. Over half (50.4%) of families had annual household incomes <$20 000. After adjustment for potential confounders, household chaos was associated with infant WFL z-score (0.02; 95% CI 0.001, 0.04; p = 0.04) at 12 months. We did not observe associations between chaos and infant breastfeeding, sleep or screen time.
CONCLUSIONS: Higher household chaos was associated with greater infant weight at 12 months, but there was no evidence of mediation by breastfeeding, sleep or screen time.
