Context: The proportion of children eating dinner with their families decli
nes with age and has decreased over time. Few data exist concerning the nut
ritional effect of eating family dinner.
Objective: To examine the associations between frequency of eating dinner w
ith family and measures of diet quality.
Design: Cross-sectional.
Setting: A national convenience sample.
Participants: There were 8677 girls and 7525 boys in the study, aged 9 to 1
4 years, who were children of the participants in the ongoing Nurses' Healt
h Study II.
Main Outcome Measures: We collected data from a self-administered mailed su
rvey, including food and nutrient intakes from a validated semiquantitative
food frequency questionnaire. Main outcome measures included servings per
day of selected foods and food groups, daily intakes of selected macronutri
ents and micronutrients, and frequency of multivitamin use.
Results: Approximately 17% of participants ate dinner with members of their
family never or some days, 40% on most days, and 43% every day. More than
half of the 9-year-olds ate family dinner every day, whereas only about one
third of l-li-year-olds did so. In age- and sex-adjusted logistic regressi
on models, the odds ratios associated with a frequency of family dinner of
most days compared with never or some days, or every day compared with most
days, were as follows: for eating at least 5 servings per day of fruits an
d vegetables, 1.45 (95% confidence interval [CI], 1.37-1.53); for eating an
y fried foods away from home, 0.67 (95% CI, 0.64-0.70); and for drinking an
y soda, 0.73 (95% CI, 0.66-0.80). Multiple linear regression showed that an
increased frequency of family dinner was also associated with substantiall
y higher intake of several nutrients, including fiber, calcium, folate, iro
n, vitamins B-6, B-12, C, and E; lower glycemic load; and lower intake of s
aturated and trans fat as a percentage of energy. We observed little or no
effect on intakes of whole dairy products, red meat, or snack foods. Patter
ns were similar for boys and girls.
Conclusions: Eating family dinner was associated with healthful dietary int
ake patterns, including more fruits and vegetables, less fried food and sod
a, less saturated and trans fat, lower glycemic load, more fiber and micron
utrients from food, and no material differences in red meat or snack foods.
