Objectives: There has been a growing concern that maternal employment could have adverse or beneficial effects on children’s health. Although recent studies demonstrated that maternal employment was associated with a higher risk of childhood overweight, the evidence remains sparse in Asian countries. We sought to examine the relationship between maternal working hours and early childhood overweight in a rural town in Okayama Prefecture. Methods: In February 2008, questionnaires were sent to parents of all preschool children aged ≥3 yr in the town to assess maternal working status (working hours and form of employment), children’s body mass index, and potential confounders. Childhood overweight was defined following the age and sex-specific criteria of the International Obesity Task Force. Odds ratios (ORs) and 95% confidence intervals (CIs) for childhood overweight were estimated in a logistic regression. We used generalized estimating equations with an exchangeable correlation matrix, considering the correlation between siblings. Results: We analyzed 364 preschool children. Adjusting for each child’s characteristics (age, sex), mother’s characteristics (age, obesity, educational attainment, smoking status, and social participation), and family’s characteristics (number of siblings), children whose mothers work Conclusion: Short maternal working hours are associated with a lower odds of early childhood overweight.
