However, it is unclear what role job instability plays in this relationship; therefore, this study examined whether children whose mothers experienced unemployment were more likely to have greater increases in body mass index (BMI) as compared with children whose mothers were stably employed. The effects of unemployment benefits, welfare and number of hours worked were also explored.Methods A multiple regression analysis was used to analyse changes in BMI over a 4-year period using the National Longitudinal Survey of Youth. In all, 4890 US children, aged 2–16 at baseline, were included in the analysis.Results As compared with children of mothers who were employed full-time and did not receive welfare, children of mothers who experienced unemployment and received unemployment benefits were not more likely to have significantly different changes in BMI. Yet children of mothers who experienced unemployment and did not receive unemployment benefits were significantly more likely to have greater increases in BMI. These results were also shown in models which controlled for height. This supports the conclusion that adiposity changes, and not simply growth-rate differences, account for the different BMI changes between groups.Conclusion Aspects of maternal employment other than number of work hours are associated with child BMI, including unemployment events and what type of support a mother receives during the time of unemployment. This has implications for policies that relate to benefits for mothers who lose their jobs. ER -
