目的：调查环境条件对正常体重与超重男性青少年午餐时间能量摄入的影响。设计：健康的 15-17 岁青少年（19 名正常体重，19 名超重）在实验室环境下参加午餐测试。比较了四种情况：集体进餐、单独进餐、边看电视边进餐、边听音乐边进餐。随意提供相同的菜单（两种固体食物，三种饮料）。 结果：观察到膳食条件之间从固体食物（而非饮料）摄入的能量存在显着的组间差异：正常体重的参与者在听音乐时摄入的固体物质（5731 +/- 426 kJ）比单独进食时（5012 +/- 364 kJ，P = 0.026）或团体进食时（4974 +/- 272 kJ，P = 0.049）。而超重参与者在看电视时（5806 +/- 330 kJ）比集体进食（5208 +/- 201 kJ，P = 0.014）或听音乐时（5288 +/- 255 kJ，P = 0.035）吃更多的固体食物。平均而言，与集体进食（7348 +/- 445 kJ，P = 0.037）或听音乐（7532 +/- 435 kJ，P = 0.049）相比，仅超重者在看电视时（8527 +/- 535 kJ）午餐时的总能量摄入量（固体加液体）有所增加。结论：环境条件调节青少年和青少年午餐时的总能量摄入量。对外部因素的易感性可能会受到体重状况的影响。这些影响是否会反过来影响能量平衡和体重状况仍有待研究。 (C) 2012 Elsevier Ltd. 保留所有权利。
Objective: To investigate the influence of environmental conditions on energy intake at lunch time in normal-weight versus overweight male adolescents.Design: Healthy 15-17 year-old adolescents (19 normal-weight, 19 overweight) participated in lunch tests under laboratory settings. Four conditions were compared: eating in groups, eating alone, eating alone while viewing television, eating alone while listening to music. The same menus (two solid foods, three drinks) were offered ad libitum.Results: Significant group differences between meal conditions were observed for energy intake from solid foods, but not from drinks: normal-weight participants ate more solids while listening to music (5731 +/- 426 kJ) than when eating alone (5012 +/- 364 kJ, P = 0.026) or in groups (4974 +/- 272 kJ, P = 0.049). whereas overweight participants ate more solid foods while viewing television (5806 +/- 330 kJ) than when eating in groups (5208 +/- 201 kJ, P = 0.014) or while listening to music (5288 +/- 255 kJ, P = 0.035). On average, total energy intake at lunch (solids plus liquids) was found to be increased only in the overweight when viewing television (8527 +/- 535 kJ) compared to eating in group (7348 +/- 445 kJ, P = 0.037) or while listening to music (7532 +/- 435 kJ, P = 0.049).Conclusion: Environmental conditions modulate total energy intake at lunch in adolescents and susceptibility to external factors can be affected by weight status. Whether such effects can in turn affect energy balance and weight status remains to be investigated. (C) 2012 Elsevier Ltd. All rights reserved.
