Extensive studies have revealed the importance of a healthy lifestyle and the role of each lifestyle factor in health. However, lifestyle factors have rarely been studied simultaneously. The authors propose an integrated approach to summarize total healthfulness of lifestyles and to enhance understanding of lifestyle patterns across countries.
The authors created an overall measure of lifestyle called the Lifestyle Index (LI), integrating diet, physical activity, smoking, and alcohol use to provide a global tool of monitoring healthfulness and patterns of lifestyles. Using the LI, the authors conducted a cross-national comparison between China (n = 8352) and the United States (n = 9750).
The LI effectively reflected the healthfulness of lifestyle components in both countries. The mean of the LI scores was slightly higher in China than the US. Scores of diet quality, physical activity, and smoking were higher in China, but scores of alcohol behavior were higher in the US. Similar lifestyle patterns but different unhealthy behaviors were identified in these countries.
An assessment of total healthfulness of lifestyles and a better understanding of lifestyle patterns across countries using the LI can provide practical guidance to developing and targeting public health promotion activities to improve global public health.
广泛的研究揭示了健康生活方式的重要性以及每种生活方式因素在健康中的作用。然而，生活方式因素很少被同时研究。作者提出一种综合方法，以总结生活方式的总体健康程度，并增进对不同国家生活方式模式的理解。
作者创建了一种名为生活方式指数（LI）的总体生活方式衡量指标，整合了饮食、身体活动、吸烟和饮酒情况，以提供一个监测健康程度和生活方式模式的全球工具。作者使用LI对中国（n = 8352）和美国（n = 9750）进行了跨国比较。
LI有效反映了两国生活方式各组成部分的健康程度。中国的LI得分均值略高于美国。中国在饮食质量、身体活动和吸烟方面的得分较高，但美国在饮酒行为方面的得分较高。在这些国家中发现了相似的生活方式模式，但存在不同的不健康行为。
使用LI评估生活方式的总体健康程度并更好地理解不同国家的生活方式模式，可以为制定和针对公共卫生促进活动提供实际指导，以改善全球公共卫生。
