UNASSIGNED: This study was a case-control study, conducted on school-age (7-13 years) children. Cases were healthy children who had a body mass index (BMI) percentile of≥85th for age and sex (n=102). Sex-matched children with a BMI percentile between 5th and 85th were considered as control group (n=102). Dietary data were collected using a validated 168-item food frequency questionnaire. Sleep quality was assessed by Pittsburgh sleep quality index. Binary logistic regression was used to assess the association between DPs, sleep quality, and overweight/obesity.
UNASSIGNED: Three DPs were identified: \"Low-energy healthy\", \"High-energy healthy\" and \"Unhealthy diet\". Adherence to the first and second DPs was associated with 51%-62% lower odds of overweight/obesity (Odds ratio [OR]: 0.49, 95% CI: 0.24-0.97, and 0.38, 95% CI: 0.15-0.94, respectively, P<0.050). However, we found no significant association for the third DP with overweight/obesity. Furthermore, there was no significant association between sleep quality/duration and overweight/obesity. The interactions of DPs and sleep quality/duration with overweight/obesity were not significant.
UNASSIGNED: Eating a diet high in white meats, eggs, vegetables, fruits and juices, nuts, dairy products, whole grains, and low in refined grains and snacks is associated with a lower likelihood of overweight/obesity in children. This inverse association does not depend on sleep quality/duration.
■本研究为病例对照研究,对学龄儿童(7-13岁)进行。病例为健康儿童,其年龄和性别的体重指数(BMI)百分位数≥85(n=102)。BMI百分位数在第5至第85位之间的性别匹配儿童被视为对照组(n=102)。使用经过验证的168项食物频率问卷收集饮食数据。采用匹兹堡睡眠质量指数评估睡眠质量。二元逻辑回归用于评估DP之间的关联,睡眠质量,和超重/肥胖。
■确定了三个DP:“低能耗健康”,“高能量健康”和“不健康饮食”。坚持第一次和第二次DPs与超重/肥胖几率降低51%-62%相关(赔率[OR]:0.49,95%CI:0.24-0.97,和0.38,95%CI:0.15-0.94,分别P<0.050)。然而,我们发现第三种DP与超重/肥胖无显著关联.此外,睡眠质量/持续时间与超重/肥胖之间无显著关联.DPs和睡眠质量/持续时间与超重/肥胖的交互作用不显著。
■吃高白肉,鸡蛋,蔬菜,水果和果汁,坚果,乳制品,全谷物,低精制谷物和零食与儿童超重/肥胖的可能性较低有关。这种逆关联不取决于睡眠质量/持续时间。
