随着我国社会经济的发展,人们生活水平的提高和生活节奏的加快,越来越多的人经常选择在外就餐。不仅仅是城市居民,在外就餐的儿童、青少年和农村居民的比例也呈不断增长趋势。在家外制售的食物能量密度高,总脂肪、饱和脂肪酸、反式脂肪酸、蛋白质、胆固醇、添加糖、钠以及食品添加剂的含量高,隐含了诸多不利于健康的膳食营养风险因素。在外就餐时会不自觉地进食过量,选择食物较为随意不够理性,由于社交的需要,伴随在外就餐的饮酒行为也更为频繁。因此,经常在外就餐者超重、肥胖的发病风险增高。本文就在外就餐行为与超重、肥胖及其相关指标(BMI、体脂、体重增长)的相关性研究进行综述。 With the social and economic development of our country, people’s living standards are improving and the pace of life is accelerating.

Eating out unconsciously when eating out of excess, the choice of food is more random and not rational, due to social needs, accompanied by eating alcohol drinking more frequently. Therefore, often over-diners are overweight, the incidence of obesity is increased.
