To evaluate potential associations between diet- and physical activity-related lifestyle patterns and obesity indices in a cohort of children.
Dietary and physical activity information and anthropometric indices were collected from 1138 children (53% girls; age, 11.2 ± 0.7 years). Dietary intake was evaluated with two 24-hour recalls, which were analyzed for nutrient and food intake, eating frequency, and meal quality. Principal component analysis was used to extract salient lifestyle patterns.
Five lifestyle behavioral patterns were identified. The "dinner, cooked meals and vegetables pattern," a multidimensional lifestyle pattern including the consumption of vegetables, cooked meals, and eating dinner, was negatively associated with all obesity indices, even after adjustment for potential confounders and exclusion of low energy reporters. A "high fiber pattern," representing high consumption of whole-grain cereals, legumes, and low intake of sugar-sweetened beverages was negatively correlated with obesity indices; when the analysis included only acceptable energy reporters, these associations became non-significant, except for triceps skinfolds.
Our findings are supportive of the synergistic or conditional effects of distinct lifestyle-related behaviors on obesity. Although these results are hypothesis-generating and need replication, they suggest potential preventive approaches, interventional approaches, or both to combat childhood obesity.
在儿童队列中评估与饮食和身体活动相关的生活方式模式与肥胖指数之间的潜在关联。
从 1138 名儿童(53%为女孩;年龄 11.2±0.7 岁)中收集饮食和身体活动信息以及人体测量学指数。通过两次 24 小时回顾法评估饮食摄入,分析营养素和食物摄入、进食频率和膳食质量。采用主成分分析法提取显著的生活方式模式。
确定了五种生活方式行为模式。“晚餐、熟食和蔬菜模式”,这一多维度生活方式模式包括蔬菜、熟食和吃晚餐,与所有肥胖指数呈负相关,即使在调整了潜在混杂因素并排除低能量报告者后也是如此。“高纤维模式”,代表全谷物、豆类的高消费和低糖饮料的低摄入,与肥胖指数呈负相关;当仅包括可接受能量报告者时,除三头肌皮褶外,这些关联变得不显著。
我们的发现支持不同与饮食相关的行为对肥胖的协同或条件作用。尽管这些结果是假设性的,需要复制,但它们表明了潜在的预防方法、干预方法或两者兼而有之,以对抗儿童肥胖。
