Using a unique dataset, this study investigates the impact of engaged (to capture quality of time) and disengaged time of both mothers and fathers on the probability a child will be overweight for two age groups of children: 9-11 and 13-15. We find that overall the quality of time, as measured by engaged time, is not marginally more important than disengaged time with the child for both age groups. Counterfactual examination reveals some interesting results: if parents of overweight children adopt the average parental time inputs of parents of healthy weight children, ceteris paribus, the predicted probability of the children being overweight decreases by 15 % and 11 % for the younger age group and the older age group, respectively. If fathers are completely uninvolved with their children, the probability of being overweight increases by an average of 116 % across age groups. If mothers are completely uninvolved with their children, the probability of being overweight increases by an average of 98 % across age groups
