Abstract

Objective: To determine the variance in percent body fat between and within families as measured by dual-energy x-ray absorptiometry (DXA). Methods: Percent body fat (%BF) assessed in 95 females, 120 males (included 54 sets of biological siblings) using DXA. Physical activity questionnaire used to assess current physical activity habits in each participant. Results: Variance in %BF between and within families is similar. Amount of television viewing and levels of physical activity can affect %BF. Discussion: A model such as the one derived in this study can be a useful tool in intervention programs implemented to decrease obesity.
