To examine lunch sources during the school week among students and the associations with fruits and vegetable (F&V) and sugar-sweetened beverage (SSB) consumption.
Students (n = 23 680) from 43 Ontario, Canada, secondary schools completed a health behaviour survey in the Year 1 COMPASS study. Analysis used generalized linear mixed effects models.
The most frequently reported lunch source was home (2.9 days per school week), then the school cafeteria (1.1) and fast-food places or restaurants (FFRs) (0.9). Eating a home lunch was associated with having less spending money, white ethnicity, and females; whereas cafeteria lunch was associated with more spending money, lower school grade, and females. A FFR lunch was associated with males, more spending money, and higher physical activity. Greater frequency of a home lunch was associated with greater F&V consumption. Greater frequency of a FFR lunch was associated with more frequent SSB consumption. Cafeteria lunches were associated with increases in both SSB and F&V.
Eating a lunch obtained from outside of the home is a regular behaviour among students. Sources of school-week lunches may have an important influence on dietary intake among youth. These findings reinforce the need for strategies to promote healthier lunch sources and healthier food options.
研究学生在上学期间的午餐来源，以及这些来源与水果和蔬菜（F&V）及含糖饮料（SSB）消费之间的关联。
来自加拿大安大略省43所中学的学生（n = 23680）在COMPASS研究的第1年完成了一项健康行为调查。分析采用广义线性混合效应模型。
最常报告的午餐来源是家里（每周上学日2.9天），其次是学校食堂（1.1天）和快餐店或餐厅（FFR）（0.9天）。在家吃午餐与零花钱较少、白人种族和女性有关；而在食堂吃午餐与零花钱较多、年级较低和女性有关。在FFR吃午餐与男性、零花钱较多和体育活动较多有关。在家吃午餐的频率越高，F&V的消费量就越大。在FFR吃午餐的频率越高，SSB的消费就越频繁。食堂午餐与SSB和F&V的消费增加都有关。
在家外获取午餐是学生的一种常见行为。上学期间午餐的来源可能对青少年的饮食摄入有重要影响。这些发现强化了制定策略以促进更健康的午餐来源和更健康的食物选择的必要性。
