To investigate the association between health literacy (HL) and unhealthy lifestyle behaviours and to explore the moderating role of social connectedness in this relationship in older adults in Switzerland. We used data from 1,455 respondents to Wave 8 of the Survey of Health, Ageing, and Retirement in Europe (SHARE). Associations between the number of unhealthy lifestyle behaviours (smoking, risky alcohol consumption, suboptimal daily consumption of fruits/vegetables, lack of vigorous physical activity) and HL were examined using multivariable Poisson regression models, which allowed for interactions between HL and social connectedness to test the moderation hypothesis. Respondents with inadequate HL were significantly more likely to have a higher number of unhealthy lifestyle behaviours than respondents with sufficient HL. We found a stronger positive association between inadequate HL and the number of unhealthy lifestyle behaviours among socially isolated individuals. Greater social connectedness seems to buffer the negative impact of inadequate HL on unhealthy lifestyle behaviours in older adults, highlighting the importance of good HL for healthy lifestyles, especially in individuals with low social reserve.
调查健康素养（HL）与不良生活方式行为之间的关联，并探讨社会联系在瑞士老年人中这种关系中的调节作用。
我们使用了来自欧洲健康、老龄化和退休调查（SHARE）第 8 波的 1455 名受访者的数据。使用多变量泊松回归模型检查了不健康生活方式行为（吸烟、危险饮酒、每日水果/蔬菜摄入量不足、缺乏剧烈身体活动）与 HL 之间的关联，该模型允许 HL 和社会联系之间进行交互，以检验调节假设。与具有足够 HL 的受访者相比，HL 不足的受访者更有可能具有更多的不健康生活方式行为。我们发现，在社会孤立的个体中，HL 不足与不健康生活方式行为的数量之间存在更强的正相关关系。更强的社会联系似乎缓冲了 HL 不足对老年人不健康生活方式行为的负面影响，突出了良好 HL 对健康生活方式的重要性，尤其是在社会储备低的个体中。
