Children of single-parent households are at a higher risk of obesity: A systematic review

The goal of this systematic review was to evaluate whether children living in single-parent households have a higher risk of obesity. Of the 539 studies identified using keywords, a total of 10 original studies met the inclusion criteria for this review. The outcome measures included objective assessment of adiposity (weight or body mass index (BMI)), dietary consumption, physical activity, and/or obesogenic behaviors (bedroom television, elevated television viewing time, insufficient physical activity, and infrequent family meals). Overall, the studies found higher BMIs and obesogenic behaviors in children of single-parent households. Characteristics identified with this association is comprised of being most prevalent among girls and Black children. Possible explanations for this association include single-parent households having higher time demands due to the lack of shared household responsibilities. Subsequently, a reduction of homemade meals, shared family meals, and physical activity can occur. Also, lower incomes and higher instability related to living transitions may be other possible challenges experienced in single-parent households. Based on the limited number of studies found, further research of the obesity risk in children from single-parent families is recommended. The findings can help provide clinicians and public health programs with a better understanding of how to effectively target family-based interventions for this population.
