背景：墨西哥肥胖率和非必需品[高饱和脂肪和/或添加糖(HSFAS)产品和含糖饮料(SSB)]的摄入量很高。重要的是要了解HSFAS产品和SSB的摄入量是否与它们的消费环境相关。目的：我们的目标是估计总能量和可自由支配食物(HSFAS产品和SSB)摄入量和进食环境(用餐时间、活动和地点)之间的关联。方法：我们使用了来自2012年墨西哥国家健康和营养调查的10087名参与者的数据。膳食摄入量是通过24小时的饮食回忆来估计的，其中包括关于用餐时间、活动和每种食物被消费的地点的问题。结果：与早餐相比，HSFAS产品贡献的能量百分比在午间点心时高16-29个百分点(各年龄段)，午餐和墨西哥早午餐时低16-23个百分点；SSB产品贡献的能量百分比在早餐时高3.4-7.6个百分点(P<；0.05)。在许多年龄段和用餐时间，我们发现，与只坐着吃饭相比，看电视时HSFAS的能量百分比高出5.3-14个百分点(P<；0.05)。与在家用餐相比，街头HSFAS高出12~26个百分点，SSB高3.4~6.0个百分点，单位高2.9~15个百分点(P<0.05)。
Background: The prevalence of obesity and the intake of discretionary foods [high saturated fat and/or added sugar (HSFAS) products and sugar-sweetened beverages (SSBs)] are high in Mexico. It is important to understand whether the intakes of HSFAS products and SSBs are associated with the context in which they are consumed.Objective: Our aim was to estimate the associations between total energy and discretionary food (HSFAS products and SSBs) intakes and the context of eating (mealtime, activity, and place).Methods: We used data from 10,087 participants aged >= 1y from the Mexican National Health and Nutrition Survey 2012. Dietary intake was estimated through a 24-h dietary recall that included questions on mealtime, activity, and place in which each food item was consumed. The associations between energy and discretionary food intakes and the context of eating were estimated by using multiple linear regression stratified by age group and adjusted for sociodemographic variables.Results: Compared with breakfast, the percentage of energy that HSFAS products contributed was 16-29 (range in all age groups) percentage points higher during midafternoon snacks and 16-23 percentage points lower at lunch and almuerzo (Mexican brunch); the percentage of energy from SSBs was 3.4-7.6 percentage points higher during midmorning snacks (P < 0.05). In many age groups and mealtimes, we found that compared with eating only while seated, the percentage of energy as HSFAS was 5.3-14 percentage points higher when watching television (P < 0.05). Compared with eating at home, the percentage of energy from HSFAS was 12-26 percentage points higher on the street and the percentage of energy from SSBs was 3.4-6.0 percentage points higher at school and 2.9-15 percentage points higher at work (P
