本研究旨在确定低收入社区居民购买含糖饮料(SSB)最多的商店类型，并确定购买地点与人口统计学特征之间的关系。参与者完成了一份饮料频率问卷，并确定了他们购买最多SSB的商店类型(例如，街角商店、连锁店)。设定美国加利福尼亚州旧金山湾区四个城市的8个低收入社区。参与者年龄在18-88岁之间的1132名报告消费SSB的个人样本，他们确认为非裔美国人(41%)、拉丁裔(29%)、白人(17%)和亚洲人(6%)。结果根据对低收入社区的调查，街角商店是购买最多SSB的主要来源(28%)，其次是折扣商店(18%)和连锁店(16%)。在完全调整的模式中，教育程度较低的人比所有其他类型的商店更有可能从街角商店或折扣杂货店购买商品。与白人参与者相比，非洲裔美国人更频繁地从街角商店、折扣杂货店和连锁店购买商品，而拉美裔美国人更频繁地从折扣食品杂货店购买商品。结论购买SSB的商店类型广泛，购买模式的人口统计学差异表明，需要更广泛的方法来充分捕捉SSB税和其他旨在减少SSB消费的干预措施的影响，特别是在低收入社区。
ObjectiveThe present study aimed to determine the store types from which people in low-income neighbourhoods purchase most sugar-sweetened beverages (SSB) and to identify associations between purchasing location and demographic characteristics.DesignStreet-intercept surveys of passers-by near high foot-traffic intersections in 2016. Participants completed a beverage frequency questionnaire and identified the type of store (e.g. corner store, chain grocery) from which they purchased most SSB.SettingEight low-income neighbourhoods in four Bay Area cities, California, USA.ParticipantsSample of 1132 individuals who reported consuming SSB, aged 18–88 years, who identified as African-American (41 %), Latino (29 %), White (17 %) and Asian (6 %).ResultsBased on surveys in low-income neighbourhoods, corner stores were the primary source from which most SSB were purchased (28 %), followed by discount stores (18 %) and chain groceries (16 %). In fully adjusted models, those with lower education were more likely to purchase from corner stores or discount groceries than all other store types. Compared with White participants, African-Americans purchased more frequently from corner stores, discount groceries and chain groceries while Latinos purchased more frequently from discount groceries.ConclusionsThe wide range of store types from which SSB were purchased and demographic differences in purchasing patterns suggest that broader methodological approaches are needed to adequately capture the impact of SSB taxes and other interventions aimed at reducing SSB consumption, particularly in low-income neighbourhoods.
