OBJECTIVE From 2015-19, the Government of Ontario expanded privatized sales of alcohol, licensing 450 grocery stores to sell beer, cider, and wine. The impacts of a nearby grocery store gaining an alcohol license on adults' alcohol use in Ontario are examined, including whether impacts differed by gender. METHODS Data from 2015-2019 Canadian Community Health Survey participants in Ontario (age 20+), living within 1000m and 1500m of grocery stores that gained a license to sell alcohol and propensity matched controls were included (1000m n=14,052, 1500m n=30,486). Alcohol use outcomes included past 7-day number of standard drinks consumed, near-daily drinking (4+ days/week), and heavy drinking (5+ drinks in men/4+ in women, ≥once/month). Gender-specific difference-in-differences (DiD) analyses compared changes in alcohol use pre- to post-intervention in intervention and control populations. RESULTS Decreases in past 7-day drinks, near-daily drinking, and heavy drinking were observed post-intervention in both intervention and control populations. At the 1000m level, adjusted DiD analyses showed past 7-day drinking in women (RR=1.21, 95%CI: 0.88-1.60), and heavy drinking in men (OR=1.38, 95%CI: 0.92-2.08), had effect sizes above one, a relative increase over controls, though confidence intervals crossed one. Findings did not indicate significant differences in alcohol use in intervention relative to controls for other alcohol use measures and at 1500m. CONCLUSIONS Findings suggest no association between a partial alcohol deregulation initiative in Ontario and alcohol use from 2015-19. It is important to monitor the impacts on alcohol use over time as further alcohol deregulation plans in Ontario and other jurisdictions are considered.

加拿大安大略省杂货店销售酒精的影响：前后研究。

目标 2015-19 年间，安大略省政府扩大了酒类的私有化销售，授权 450 家杂货店销售啤酒、苹果酒和葡萄酒。研究了附近一家杂货店获得酒精许可证对安大略省成年人饮酒的影响，包括影响是否因性别而异。方法 2015-2019 年安大略省加拿大社区健康调查参与者（20 岁以上）的数据，居住在距离杂货店 1000m 和 1500m 范围内的获得酒精销售许可证和倾向匹配对照的数据（1000m n=14,052，1500m n=30,486） ）。酒精使用结果包括过去 7 天消耗的标准饮酒量、几乎每天饮酒（每周 4 天以上）和大量饮酒（男性饮酒 5 次以上/女性饮酒 4 次以上，≥一次/月）。性别特异性双重差异（DiD）分析比较了干预人群和对照组人群干预前后饮酒的变化。结果 干预后，干预组和对照组人群的过去 7 天饮酒量、近乎每日饮酒量和大量饮酒量均有所减少。在 1000m 水平上，调整后的 DiD 分析显示，女性过去 7 天饮酒（RR=1.21，95%CI：0.88-1.60）和男性酗酒（OR=1.38，95%CI：0.92-2.08），效应大小高于 1，相对于对照而言相对增加，尽管置信区间跨越 1。研究结果并未表明，相对于其他酒精使用措施和 1500m 的对照，干预中的酒精使用量没有显着差异。结论 调查结果表明，安大略省部分酒精放松管制举措与 2015-19 年的饮酒之间没有关联。随着安大略省和其他司法管辖区考虑进一步放松酒精管制计划，随着时间的推移，监测对酒精使用的影响非常重要。
