Abstract 摘要

Objective 目的

To measure the energy content of frequently ordered meals from full service and fast food restaurants in five countries and compare values with US data.

测定5个国家的全服务式餐厅与快餐厅中常点菜品所含能量,并与美国的数据进行比较。

Design 设计

Cross sectional survey.

横断面调查

Setting 场景

223 meals from 111 randomly selected full service and fast food restaurants serving popular cuisines in Brazil, China, Finland, Ghana, and India were the primary sampling unit; 10 meals from five worksite canteens were also studied in Finland. The observational unit was frequently ordered meals in selected restaurants.

从巴西、中国、芬兰、加纳和印度的111个全服务式餐厅与快餐厅中随机挑选223中菜品作为主要研究样本;同时对芬兰5个工作场所餐厅的10份餐食也进行了分析。

Main outcome measure 主要预后指标

Meal energy content, measured by bomb calorimetry.

通过弹式热量计测定餐食中能量含量

Results 结果

Compared with the US, weighted mean energy of restaurant meals was lower only in China (719 (95% confidence interval 646 to 799) kcal versus 1088 (1002 to 1181) kcal; P<0.001). In analysis of variance models, fast food contained 33% less energy than full service meals (P<0.001). In Finland, worksite canteens provided 25% less energy than full service and fast food restaurants (mean 880 (SD 156) versus 1166 (298); P=0.009). Country, restaurant type, number of meal components, and meal weight predicted meal energy in a factorial analysis of variance (R2=0.62, P<0.001). Ninety four per cent of full service meals and 72% of fast food meals contained at least 600 kcal. Modeling indicated that, except in China, consuming current servings of a full service and a fast food meal daily would supply between 70% and 120% of the daily energy requirements for a sedentary woman, without additional meals, drinks, snacks, appetizers, or desserts.

与美国相比,仅有中国餐馆提供的餐食中加权后平均能量较低( 719 (95% 可信区间 646 to 799) kcal vs. 1088 (1002 to 1181) kcal; P<0.001)。变异度模型分析显示,与全服务式餐食相比,快餐所含热卡减少33% (P<0.001)。在芬兰,与全服务式餐厅及快餐厅相比,工作场所餐厅提供的餐食能量减少25%(平均 880 (SD 156) vs. 1166 (298); P=0.009)。多因素方差分析显示,不同国家、餐馆类型、餐食内容物数量及其重量与餐食能量有关(R2=0.62, P<0.001)。94%的全服务式餐食以及72%的快餐所含能量超过600 kcal。模型显示,除中国外,在没有额外餐食、饮料、零食、开胃菜及甜品的情况下,每日消费全服务式餐食或快餐能够提供久坐女性每日所需能量的70%-120%。

Conclusion 结论

Very high dietary energy content of both full service and fast food restaurant meals is a widespread phenomenon that is probably supporting global obesity and provides a valid intervention target.

全服务式餐馆及快餐厅餐食含有极高的能量,这是一个普遍存在的现象,可能造成全球性的肥胖问题,并可能成为有效的干预目标。
