This study aimed to describe street food purchases in cities from Central Asia, considering customers' characteristics and the nutritional composition of the foods and beverages. Cross-sectional studies were conducted in 2016/2017 in Dushanbe (Tajikistan), Bishkek (Kyrgyzstan), Ashgabat (Turkmenistan) and Almaty (Kazakhstan). Direct observation was used to collect data on the purchases made by street food customers, selected by random and systematic sampling. Nutritional composition was estimated using data from chemical analyses, food composition tables or food labels. A total of 714 customers (56.6% females, 55.5% aged ≥35 years, 23.3% overweight/obese) were observed, who bought 852 foods and beverages, the most frequent being savoury pastries/snacks (23.2%), main dishes (19.0%), sweet pastries/confectionery (17.9%), tea/coffee (11.3%) and soft drinks/juices (9.8%). Fruit was the least purchased food (1.1%). Nearly one-third of customers purchased industrial food items (31.9%). The median energy content of a street food purchase was 529 kcal/serving. Saturated and -fat median contents were 4.7 g/serving and 0.36 g/serving (21.4% and 16.5% of maximum daily intake recommendations, respectively). Median sodium and potassium contents were 745 mg/serving (37.3% of maximum recommendation) and 304 mg/serving (8.7% of minimum recommendation), respectively. In general, the purchases observed presented high contents of energy, saturated-fat, -fat and sodium, and low levels of potassium. Policies towards the improvement of these urban food environments should be encouraged.
本研究旨在描述中亚城市的街头食品购买情况,考虑到顾客的特点以及食品和饮料的营养成分。2016/2017 年在杜尚别(塔吉克斯坦)、比什凯克(吉尔吉斯斯坦)、阿什哈巴德(土库曼斯坦)和阿拉木图(哈萨克斯坦)进行了横断面研究。通过随机和系统抽样选择街头食品顾客进行直接观察,以收集购买食品的数据。营养成分是通过化学分析、食物成分表或食物标签中的数据来估计的。共观察到 714 名顾客(56.6%为女性,55.5%年龄≥35 岁,23.3%超重/肥胖),他们购买了 852 种食品和饮料,最常见的是咸味糕点/小吃(23.2%)、主菜(19.0%)、甜糕点/糖果(17.9%)、茶/咖啡(11.3%)和软饮料/果汁(9.8%)。水果是购买最少的食物(1.1%)。近三分之一的顾客购买了工业食品(31.9%)。街头食品购买的中位数能量含量为 529 千卡/份。饱和脂肪和反式脂肪的中位数含量分别为 4.7 克/份和 0.36 克/份(分别为每日最大摄入量建议的 21.4%和 16.5%)。中位数钠和钾含量分别为 745 毫克/份(最大推荐量的 37.3%)和 304 毫克/份(最小推荐量的 8.7%)。总的来说,观察到的购买食品具有高热量、高饱和脂肪、高反式脂肪和高钠含量,以及低钾含量。应鼓励采取政策改善这些城市食品环境。
