Height, weight, and body mass index (BMI) were assessed in a sample of 1974 monozygotic
and 2097 dizygotic male twin pairs. Concordance rates for different degrees of overweight
were twice as high for monozygotic twins as for dizygotic twins. Classic twin methods
estimated a high heritability for height, weight, and BMI, both at age 20 years (. 80,. 78, and.
77, respectively) and at a 25-year follow-up (. 80,. 81, and. 84, respectively). Height, weight,
and BMI were highly correlated across time, and a path analysis suggested that the major …
