BACKGROUND/OBJECTIVES: The aim of this study was to evaluate the reliability of a food menu to measure energy and macronutrient intake within the laboratory and under real-life conditions in adolescents.
SUBJECTS/METHODS: A total of 12 boys and 8 girls (age 14.3 (s.d. 2.4) years, body mass index (BMI) 20.8 (s.d. 4.0) kg/m(2)) completed two identical in-laboratory sessions (ILS) and two out-of-laboratory sessions (OLS). During the ILS, participants had ad libitum access to a variety of foods (74 items in total), which they chose from a menu every hour, for 5 h (0800-1300 h). For the OLS (1300 h until bedtime), the foods were chosen from the same menu at 1300 h and packed into containers to bring home with them.
Test-retest analysis of energy and macronutrient intake revealed no significant differences (ILS and OLS). Intra-class correlations ranged between 0.69 and 0.83 (ILS) and between 0.48 and 0.73 (OLS) for energy and macronutrient intake (all P<0.01). Within-subject coefficients of variation ranged between 12.9% and 23.5% for the ILS and between 24.0% and 37.7% for the OLS. Bland-Altman plots showed acceptable agreement. Finally, the food menu was well appreciated by the participants with a 75% appreciation rate on a visual analog scale.
This food menu provides a reasonably reliable measure of energy and macronutrient intake in adolescents, irrespective of sex and BMI, especially inside the laboratory setting. Despite the difficulties in capturing a stable measure of energy intake in research, this tool could be a useful addition to the methods currently used to assess ad libitum food intake in youth.
背景/目的：本研究旨在评估一份食物菜单在实验室环境及青少年现实生活条件下测量能量和宏量营养素摄入量的可靠性。
受试者/方法：共有12名男孩和8名女孩（年龄14.3（标准差2.4）岁，体重指数（BMI）20.8（标准差4.0）kg/m²）完成了两次相同的实验室环节（ILS）和两次实验室外环节（OLS）。在ILS期间，参与者可随意取用各种食物（共74种），他们每小时从菜单中选择食物，持续5小时（08:00 - 13:00）。对于OLS（13:00至就寝时间），食物于13:00从相同菜单中选择并装入容器带回家。
能量和宏量营养素摄入量的重测分析显示无显著差异（ILS和OLS）。能量和宏量营养素摄入量的组内相关系数在ILS中为0.69至0.83，在OLS中为0.48至0.73（均P<0.01）。受试者内变异系数在ILS中为12.9%至23.5%，在OLS中为24.0%至37.7%。Bland - Altman图显示一致性可接受。最后，参与者对该食物菜单评价良好，视觉模拟量表的赞赏率为75%。
这份食物菜单能合理可靠地测量青少年的能量和宏量营养素摄入量，无论性别和BMI如何，尤其是在实验室环境中。尽管在研究中获取稳定的能量摄入量测量存在困难，但该工具可能是目前用于评估青少年随意食物摄入量方法的有益补充。
