This study examines the extent to which healthy lifestyle behaviours co-occur in individuals. We also explore within-couples concordance in healthy lifestyle behaviours in Namibia.
Cross-sectional study.
We used data from 910 couples (1820 individuals) who were interviewed in the Namibia Demographic and Health Survey conducted in 2013. We assessed five different healthy lifestyle behaviours (alcohol non-consumption, non-cigarette smoking, healthy diet, physical exercise, and normal body mass index). An individual healthy lifestyle index (HLI) was derived by summing values across the five behaviours, with a binary indicator categorising each individual's lifestyle behaviour as 'healthy' (HLI ≥ 3) or 'unhealthy' (HLI < 3). Multivariate logistic regression models were fitted to explore the association between binary indicators of men's and their female partner's healthy lifestyles.
About 48% of men and 57% of women had at least three co-occurring healthy lifestyle behaviours. A third of couples were concordant in reporting a healthy lifestyle (HLI ≥ 3), while 27% were concordant in reporting an unhealthy lifestyle (HLI < 3). In multivariate analysis, Namibian men were almost twice (aOR, 1.90; 95%CI, 1.43-2.52) as likely to have a healthy lifestyle if their female partner also had a healthy lifestyle, compared with those who had a female partner who had an unhealthy lifestyle, after adjusting for relevant individual, partner and household characteristics.
The observed co-occurrence of healthy lifestyle behaviours and spousal concordance suggests it may be beneficial to consider couples a target for intervention when aiming to promote healthy behaviours and reduce cardiovascular diseases in Namibia.
本研究旨在探讨健康生活方式行为在个体之间的共现程度。我们还探索了纳米比亚夫妇之间健康生活方式行为的一致性。
横断面研究。
我们使用了 2013 年纳米比亚人口与健康调查中对 910 对夫妇（1820 人）进行访谈的数据。我们评估了五种不同的健康生活方式行为（不饮酒、不吸烟、健康饮食、体育锻炼和正常体重指数）。通过将五种行为的分值相加，得出一个个体健康生活方式指数（HLI），并将个体的生活方式行为分为“健康”（HLI≥3）或“不健康”（HLI<3）。采用多变量逻辑回归模型探讨男性和女性伴侣健康生活方式的二元指标之间的关联。
约 48%的男性和 57%的女性至少有三种共现的健康生活方式行为。三分之一的夫妇在报告健康生活方式方面是一致的（HLI≥3），而 27%的夫妇在报告不健康生活方式方面是一致的（HLI<3）。在多变量分析中，与女性伴侣生活方式不健康的男性相比，女性伴侣生活方式健康的男性更有可能拥有健康的生活方式（优势比，1.90；95%置信区间，1.43-2.52），调整了相关的个体、伴侣和家庭特征后。
观察到健康生活方式行为的共现和配偶的一致性表明，在纳米比亚，当旨在促进健康行为和减少心血管疾病时，将夫妇视为干预目标可能是有益的。
