儿童肥胖的行为减肥（BWL）包括改善家庭食品环境和饮食质量的指导；然而，粮食不安全是做出这些改变的障碍。本研究考察了青少年肥胖治疗过程中家庭饮食环境、膳食质量、能量摄入和体重的变化是否因食品安全状况而异，以及家庭饮食环境的变化是否与食品安全状况下饮食质量和能量摄入的变化相关。肥胖青少年（n = 82; 13.7±1.2岁）参加了为期4个月的BWL治疗。在基线和治疗后评估食品不安全、家庭食品环境（家庭食品清单[HFI]）、饮食质量（健康饮食指数[HEI]）、能量摄入和体重指数（BMI）。食物安全家庭的致肥性食物环境减少，膳食质量提高（ps < 0.01），而食物不安全家庭的致肥性食物环境减少，膳食质量提高（ps < 0.05）（平均差异，HFI: - 6.6±6.4比- 2.4±7.4;HEI: 5.1±14.4比2.7±17.7）。食物安全家庭和食物不安全家庭的青少年能量摄入和身体质量指数下降（ps < 0.03）（平均差异；能量摄入：- 287±417对- 309±434千卡/天；身体质量指数：- 1.0±1.4对- 0.7±1.4）。BWL在能量摄入和体重方面也产生了类似的减少，但在改善饮食质量和家庭食品环境方面却没有为食物不安全的青少年提供同样的好处。
Behavioral weight loss (BWL) for pediatric obesity includes guidance on improving the home food environment and dietary quality; yet food insecurity presents barriers to making these changes. This study examined if home food environment, dietary quality, energy intake, and body weight changes during adolescent obesity treatment differed by food security status, and if changes in the home food environment were associated with changes in dietary quality and energy intake by food security status. Adolescents (n = 82; 13.7 ± 1.2 years) with obesity participated in a 4-month BWL treatment. Food insecurity, home food environment (Home Food Inventory [HFI]), dietary quality (Healthy Eating Index [HEI]), energy intake, and body mass index (BMI) were assessed at baseline and post-treatment. A reduced obesogenic home food environment and improved dietary quality were observed for food secure (ps < 0.01), but not insecure households (ps > 0.05) (mean difference, HFI: −6.6 ± 6.4 vs. −2.4 ± 7.4; HEI: 5.1 ± 14.4 vs. 2.7 ± 17.7). Energy intake and BMI decreased for adolescents in food secure and insecure households (ps < 0.03) (mean difference; energy intake: −287 ± 417 vs. −309 ± 434 kcal/day; BMI: −1.0 ± 1.4 vs. −0.7 ± 1.4). BWL yielded similar reductions in energy intake and body weight yet did not offer the same benefits for improved dietary quality and the home food environment for adolescents with food insecurity.
