India is experiencing increased consumption of sugar-sweetened carbonated drinks, consumption that may be associated with increased risk of type 2 diabetes and obesity. The aim of the study was to determine the availability, price and quantity sold of 'Pepsi' and 'Coca Cola' in their 'regular' and 'diet' forms in Delhi and London.
A questionnaire about the availability, price and quantity sold per day of both regular and diet Pepsi and Coca Cola was devised and piloted. Using this, a survey of food and drink outlets within a 100 m radius of randomly selected Metro stations was conducted in both cities.
Store vendors, owners and staff of food and drink outlets.
Delhi, India; London, United Kingdom.
In Delhi, of the outlets stocking regular Pepsi and Coca Cola, only 34% sold diet versions and these were more readily available in the most affluent areas than in the poorest areas (34% v. 6%, Z=3.67, P<0.001). This social patterning was not observed in London. Little price differential between regular and diet versions of Pepsi and Coca Cola was observed in Delhi; however, profit margins were better for regular, relative to diet, Coca Cola. Sales of regular products were significantly greater than those of diet products (P<0.002).
Low availability of diet versions of Pepsi and Coca Cola in less affluent areas of Delhi is likely to exacerbate the obesity and diabetes trends. Price differentials to promote diet versions and other healthier or traditional low-energy drinks may be beneficial.
印度的含糖碳酸饮料消费呈上升趋势，这种消费可能会增加患 2 型糖尿病和肥胖症的风险。本研究旨在确定在德里和伦敦，百事可乐和可口可乐的常规型和低糖型的供应情况、价格和销售量。
设计了一份关于常规型和低糖型百事可乐和可口可乐供应情况、价格和日销售量的调查问卷，并进行了预试验。根据该问卷，在这两个城市中，对距离随机选定的地铁站 100 米范围内的食品和饮料销售点进行了调查。
商店销售人员、食品和饮料销售点的老板和员工。
印度德里；英国伦敦。
在德里，供应常规百事可乐和可口可乐的销售点中，只有 34%销售低糖型，且在最富裕地区比在最贫困地区更容易获得（34%比 6%，Z=3.67，P<0.001）。在伦敦没有观察到这种社会分布模式。在德里，常规型和低糖型百事可乐和可口可乐之间的价格差异不大；然而，相对于低糖型，常规型可口可乐的利润率更高。常规产品的销售额明显高于低糖产品（P<0.002）。
在德里较贫困地区低糖型百事可乐和可口可乐的供应不足可能会加剧肥胖和糖尿病的流行趋势。通过价格差异来推广低糖型和其他更健康或传统低能量饮料可能是有益的。
