Average dietary intake and dietary quality indicators were assessed using two 24-hour dietary recalls provided by study participants.
The researchers also assessed the overall quality of the participating children's and their parents' diets based on the USDA 2005 Health Eating Index (HEI) along with a number of other covariates.
According to them, the correlations between children's and their parents' HEI scores ranged from 0.26 to 0.29 across various child-parent dyads, such as mother-daughter and father-son.
For total energy intake they were 0.14 to 0.29, while for fat intake -0.04 to 0.28.
The researchers say that the range of the correlation measure is between -1 and 1, while 0 means no resemblance and 1 indicates a perfect resemblance.
The team also found some differences in the resemblance between different types of child-parent dyads and nutrient intakes, and by children's age and family income.
"Factors other than parental eating behaviors such as community and school, food environment, peer influence, television viewing, as well as individual factors such as self-image and self-esteem seem to play an important role in young people's dietary intake," said Dr. May A. Beydoun, co-author of the study and a former postdoctoral research fellow at the Bloomberg School.
"Our findings have a number of important public health implications. In particular, the overall weak to moderate parent-child resemblance in food groups, nutrients and healthy eating index scores suggest that interventions targeting parents could have only a moderate effect on improving their children's diet.
Nevertheless, based on our findings stratified by population groups, for interventions targeting parents, those would be more effective when targeted at mothers, minority groups, and as early as possible in childhood. We suspect that the child-parent resemblance in dietary intake may have become weaker over time, due to the growing influence of other factors outside of the family," said Wang.
The study has been published in the journal Social Science and Medicine.
