Examining the Effects of Fathers' Residency Status on Childhood Obesity.

OBJECTIVE

To examine whether fathers' residency status is associated with increased BMI z-scores among young and pre-adolescent children.

METHODS

Propensity score matching was used to examine the effects of fathers' residency status on child BMI z-scores for children between the ages of 2-5 and 9-11 years old. Fathers self-reported their residency status as either being residential or nonresidential, based on the amount of time they lived in the same household as the child enrolled in the study. We conducted a series of cross-sectional matched analyses using three waves of data from 1448 families who participated in the Fragile Families and Child Wellbeing Study.

RESULTS

We did not find a difference in BMI z-scores among children based on their father's residency status for children between the ages of 2-5 years old but did find a marginally significant difference in BMI z-scores for children between 9 and 11 years old.

CONCLUSIONS FOR PRACTICE

Our findings suggest that fathers' residency status is not associated with increased BMI z-scores among young children but may be slightly predictive of differences in BMI z-scores among pre-adolescent children. The results from our study begin to explore the scientific gains of analyzing the influence of diverse family structures on childhood obesity outcomes. Our focus on fathers' residency status adds to the literature by highlighting some of the risks and resources that fathers from diverse family structures bring to family functioning and children's health and wellbeing.
