(i) To audit the nutritional composition, promotion and cost of products available from vending machines available to young adults; and (ii) to examine the relationship between product availability and sales.
A cross-sectional analysis of snacks and beverages available and purchased at a large urban university was conducted between March and September 2014. Sales were electronically tracked for nine months.
A total of 61 vending machines were identified; 95% (n = 864) of the available snacks and 49% of beverages (n = 455) were less-healthy items. The mean (SD) nutrient value of snacks sold was: energy 1173 kJ (437.5), saturated fat 5.36 g (3.6), sodium 251 mg (219), fibre 1.56 g (1.29) and energy density 20.16 kJ/g (2.34) per portion vended. There was a strong correlation between the availability of food and beverages and purchases (R = 0.98, P < 0.001).
Vending machines market and sell less-healthy food and beverages to university students. Efforts to improve the nutritional quality are indicated and afford an opportunity to improve the diet quality of young adults, a group at risk of obesity.
（i）审核可供年轻人使用的自动售货机所售产品的营养成分、促销情况及成本；（ii）研究产品供应与销售之间的关系。
2014年3月至9月，对一所大型城市大学内自动售货机所售及所购的零食和饮料进行横断面分析。对九个月的销售情况进行电子跟踪。
共识别出61台自动售货机；95%（n = 864）的在售零食和49%的饮料（n = 455）为不健康食品。所售零食的平均（标准差）营养价值为：每份能量1173千焦（437.5）、饱和脂肪5.36克（3.6）、钠251毫克（219）、纤维1.56克（1.29）以及能量密度20.16千焦/克（2.34）。食品和饮料的供应与购买之间存在很强的相关性（R = 0.98，P < 0.001）。
自动售货机向大学生推销和售卖不健康的食品和饮料。表明需要努力提高营养质量，这为改善肥胖风险较高的年轻人的饮食质量提供了契机。
