The purpose of this study was to examine both cross-sectional and longitudinal associations between frequency of family dinner and overweight status in a large sample of 9- to 14-year-old children.
We studied a cohort of 7784 girls and 6647 boys, 9 to 14 years of age at baseline in 1996, participating in the Growing Up Today Study. From annual mailed surveys, we calculated BMI from self-reported height and weight and assessed frequency of family dinner over the previous year. We defined "overweight" as age- and sex-specific BMI >85th percentile. We performed multiple logistic regression analyses; the longitudinal analyses assessed the association of previous year family dinner consumption with 1-year incidence of becoming overweight, using prospective data from 1996 through 1999.
At baseline in 1996, 16% of participants had family dinner "never or some days," 40% on "most days," and 44% "every day." Across these categories, overweight prevalence for girls was 19.4%, 16.6%, and 16.7% and for boys was 24.6%, 23.3%, and 22.7%, respectively. In cross-sectional analyses, adjusting for potential confounders, the odds of being overweight was 0.85 [95% confidence interval (CI): 0.76, 0.96] among children who ate family dinner on "most days" or "every day" compared with those who ate family dinner "never or some days." In longitudinal multivariate models, the odds ratios between previous year frequency of eating family dinner and 1-year incidence of becoming overweight were 0.95 (95% CI: 0.78, 1.16) and 1.04 (95% CI: 0.85, 1.27) for children who ate family dinner on "most days" and "every day," respectively, compared with those who ate family dinner "never or some days."
The frequency of eating family dinner was inversely associated with overweight prevalence at baseline but not with likelihood of becoming overweight in longitudinal analyses.
本研究旨在调查9至14岁儿童大样本中家庭聚餐频率与超重状况之间的横断面和纵向关联。
我们对1996年基线时年龄在9至14岁的7784名女孩和6647名男孩组成的队列进行了研究，这些儿童参与了“今日成长研究”。通过年度邮寄调查，我们根据自我报告的身高和体重计算了体重指数（BMI），并评估了前一年家庭聚餐的频率。我们将“超重”定义为特定年龄和性别的BMI超过第85百分位数。我们进行了多项逻辑回归分析；纵向分析使用1996年至1999年的前瞻性数据，评估前一年家庭聚餐频率与超重1年发病率之间的关联。
1996年基线时，16%的参与者“从不或偶尔”进行家庭聚餐，40%的参与者“大多数日子”进行家庭聚餐，44%的参与者“每天”进行家庭聚餐。在这些类别中，女孩的超重患病率分别为19.4%、16.6%和16.7%，男孩的超重患病率分别为24.6%、23.3%和22.7%。在横断面分析中，在调整潜在混杂因素后，“大多数日子”或“每天”进行家庭聚餐的儿童超重几率为0.85[95%置信区间（CI）：0.76，0.96]，而“从不或偶尔”进行家庭聚餐的儿童超重几率为0.85[95%置信区间（CI）：0.76，0.96]。在纵向多变量模型中，与“从不或偶尔”进行家庭聚餐的儿童相比，“大多数日子”和“每天”进行家庭聚餐的儿童前一年家庭聚餐频率与超重1年发病率之间的比值比分别为0.95（95%CI：0.78，1.16）和1.04（95%CI：0.85，1.27）。
家庭聚餐频率与基线时的超重患病率呈负相关，但在纵向分析中与超重的可能性无关。
