Parental body mass index: a predictor of childhood obesity?
Cross-sectional data of 210 Chinese children aged three to 16 years, of whom 29 (13.8%) were obese, and their biological parents were statistically assessed whether the body mass index (BMI = weight/height2) of the parents were predictive of childhood obesity. Using the logistic regression and proportional hazards models to predict the probability of obesity and to control for potential confounding due to the age and sex of the children, families with one parent having a BMI score of 25 or higher were 3.7 times, and families with two such parents were five times more likely to have an obese child than families with no such parent. Childhood obesity was more markedly correlated with the mother's BMI than with the father's BMI. These findings were all stochastically significant (p < 0.05) inspite of the modest sample size. One in two parents with an obese child did not perceive their child to be overweight and 62% of the parents with an obese child did not want their child to lose weight.
