AIMS Buying and consuming no- (per cent alcohol by volume, ABV = 0.0%) and low- (ABV = >0.0% and ≤ 3.5%) alcohol beers could reduce alcohol consumption but only if they replace buying and drinking higher-strength beers. We assess whether buying new no- and low-alcohol beers increases or decreases British household purchases of same-branded higher strength beers. METHODS Generalized linear models and interrupted time series analyses, using purchase data of 64,280 British households from Kantar Worldpanel's household shopping panel, 2015-2018. We investigate the extent to which the launch of six new no- and low-alcohol beers affected the likelihood and volume of purchases of same-branded higher-strength beers. RESULTS Households that had never previously bought a same-branded higher-strength beer but bought a new same-branded no- or low-alcohol beer were less than one-third as likely to go on and newly buy the same-branded higher-strength product. When they did later buy the higher-strength product, they bought half as much volume as households that had not bought a new same-branded no- or low-alcohol beer. For households that had previously purchased a higher-strength beer, the introduction of the new same-branded no- or low-alcohol beer was associated with decreased purchases of the volume of the higher-strength beer by, on average, one-fifth. CONCLUSIONS The increased availability of new no- and low-alcohol beers does not seem to be a gateway to purchasing same-branded higher-strength beers but rather seems to replace purchases of these higher-strength products. Thus, introduction of new no- and low-alcohol beers could contribute to reducing alcohol consumption.

低强度啤酒是通往高强度啤酒的途径吗?2015-2018 年 64,280 个英国家庭的家庭购买时间序列分析。

AIMS 购买和饮用无酒精(按体积计酒精百分比,ABV = 0.0%)和低酒精(ABV = >0.0% 且 ≤ 3.5%)啤酒可以减少酒精消费,但前提是它们取代购买和饮用高浓度啤酒. 我们评估购买新的无酒精和低酒精啤酒是否会增加或减少英国家庭购买同品牌的高强度啤酒。方法 广义线性模型和间断时间序列分析,使用来自 Kantar Worldpanel 家庭购物面板的 64,280 个英国家庭的购买数据,2015-2018 年。我们调查了六种新的无酒精和低酒精啤酒的推出对购买同品牌高浓度啤酒的可能性和数量的影响程度。结果 以前从未购买过同品牌高浓度啤酒但购买新的同品牌无酒精或低酒精啤酒的家庭继续购买同品牌高浓度啤酒的可能性不到三分之一产品。当他们后来确实购买了更高浓度的产品时,他们购买的数量是没有购买新的同品牌无酒精或低酒精啤酒的家庭的一半。对于以前购买过高浓度啤酒的家庭来说,新的同品牌无酒精或低酒精啤酒的推出与高浓度啤酒的购买量平均减少五分之一有关。结论 新的无酒精和低酒精啤酒的供应增加似乎并不是购买同品牌高浓度啤酒的途径,而是似乎取代了购买这些高浓度产品。因此,引入新的无酒精和低酒精啤酒可能有助于减少酒精消费。
