Children may be at a higher risk for obesity if their father is obese..

Other studies have shown an association between two overweight parents and
higher weight in their children, and weight relationships between fathers and
sons and mothers and daughters. Researchers in this study, published in the
January issue of the International Journal of Obesity, measured the height and
weight of children from 3,285 two-parent families in Australia in 2004, when the
children were ages 4 and 5, and again in 2008 when they were ages 8 and 9.
