Pearson partial correlation coefficients (r)1 between parent and child BMI measures by dyad type and various socio-demographic and socioeconomic characteristics.

1The r was adjusted for child's age and parent's age, ethnicity, education, household income, marital status, and physical activity. In the stratified analysis, partial correlation coefficients were calculated adjusting for the same variables except the stratification variable. For example, for the father-son correlation, we controlled for child age and father's characteristics as described above. For the father-son correlation stratified by household income, we controlled child age and father's characteristics with exception of household income.2SEM: standard error of measurement.3–7Significantly different from the reference group (pNH: non-Hispanic; ref: reference group.Source: Medical Expenditure Panel Survey, 2006–2007.
