We examined the associations of physical activities and dietary behaviors with children's health and academic-behavioral problems.
We employed a Community-wide Children's Health Assessment and Planning Survey to examine physical activity, healthy meals, health status, and academic-behavioral problems in 3708 children 7 to 14 years of age. Statistical associations were examined with chi-square test and logistic regression analysis; we calculated odds ratios (ORs) and 95% confidence intervals (CIs).
Among these children, 30.2% were overweight-obese, 11.0% had academic problems, and 7.9% had behavioral problems. Children classified as healthy eaters were more likely to exercise ≥4 days/week (79.1% vs 64.6%, OR: 2.08, 95% CI: 1.14 to 2.49), less likely to be overweight-obese (27.7% vs 44.6%, OR: 0.48, CI: 0.31 to 0.73), less likely to have academic problems (9.1% vs 16.1%, OR: 0.57, 95% CI: 0.41 to 0.79) and behavioral problems (6.9% vs 13.9%, OR: 0.46, 95% CI: 0.32 to 0.66) compared with their less healthy eating peers. Physical activity and healthy meals were associated with an improved health status (p < .001). However, the proportions of children taking unhealthy meals or choosing sedentary lifestyle increased as the cohorts progressed (p < .05) from childhood (7 to 8 years) to adolescence (13 to 14 years).
Healthy (or unhealthy) lifestyle behaviors are significantly interrelated. Children who take healthy meals and exercise often are associated with better health and fewer academic and behavioral problems. Unfortunately, taking unhealthy meals and sedentary lifestyle characterize a growing proportion of young adolescents. Thus, curbing unhealthy lifestyle behaviors should start in early childhood.
我们研究了身体活动和饮食行为与儿童健康和学业行为问题之间的关联。
我们采用社区范围内的儿童健康评估和规划调查，对 3708 名 7 至 14 岁儿童的身体活动、健康饮食、健康状况和学业行为问题进行了检查。采用卡方检验和逻辑回归分析检查统计学关联；我们计算了比值比（OR）和 95％置信区间（CI）。
在这些儿童中，30.2％超重肥胖，11.0％有学业问题，7.9％有行为问题。被归类为健康饮食者更有可能每周运动≥4 天（79.1％比 64.6％，OR：2.08，95％CI：1.14 至 2.49），不太可能超重肥胖（27.7％比 44.6％，OR：0.48，CI：0.31 至 0.73），较少有学业问题（9.1％比 16.1％，OR：0.57，95％CI：0.41 至 0.79）和行为问题（6.9％比 13.9％，OR：0.46，95％CI：0.32 至 0.66）与他们饮食不健康的同龄人相比。身体活动和健康饮食与改善健康状况有关（p<0.001）。然而，随着队列从儿童期（7 至 8 岁）到青春期（13 至 14 岁）的发展，选择不健康饮食或久坐不动生活方式的儿童比例增加（p<0.05）。
健康（或不健康）的生活方式行为密切相关。经常食用健康饮食和运动的儿童与更好的健康和较少的学业和行为问题有关。不幸的是，选择不健康的饮食和久坐不动的生活方式是越来越多的青少年的特征。因此，遏制不健康的生活方式行为应从儿童早期开始。
