Previous studies suggest that having a marital partner with hypertension is associated with an individual's increased risk of hypertension, however this has not been investigated in sub-Saharan Africa despite hypertension being a common condition; the age-standardised prevalence of hypertension was 46.0% in 2013 in Namibia.
To explore whether there is spousal concordance for hypertension and hypertension control in Namibia.
Couples data from the 2013 Namibia Demographic and Health Survey were analysed. Bivariable and multivariable logistic regression models were used to explore the odds of individual's hypertension based on their partner's hypertension status, 492 couples. and the odds of hypertension control in individuals based on their partner's hypertension control (121 couples), where both members had hypertension. Separate models were built for female and male outcomes for both research questions to allow independent consideration of risk factors to be analysed for female and males.
The unadjusted odds ratio of 1.57 (CI 1.10-2.24) for hypertension among individuals (both sexes) whose partner had hypertension compared to those whose partner did not have hypertension, was attenuated to aOR 1.35 (CI 0.91-2.00) for females (after adjustment for age, BMI, diabetes, residence, individual and partner education) and aOR 1.42 (CI 0.98-2.07) for males (after adjustment for age and BMI). Females and males were significantly more likely to be in control of their hypertension if their partner also had controlled hypertension, aOR 3.69 (CI 1.23-11.12) and aOR 3.00 (CI 1.07-8.36) respectively.
Having a partner with hypertension was positively associated with having hypertension among married Namibian adults, although not statistically significant after adjustment. Partner's hypertension control was significantly associated with individual hypertension control. Couples-focused interventions, such as routine partner screening of hypertensive individuals, could be developed in Namibia.
先前的研究表明，与患有高血压的伴侣生活在一起会增加个体患高血压的风险，但在撒哈拉以南非洲地区，这一现象尚未得到调查，尽管高血压是一种常见疾病；2013 年纳米比亚的高血压标准化患病率为 46.0%。
探讨纳米比亚夫妇之间是否存在高血压和高血压控制的一致性。
对 2013 年纳米比亚人口与健康调查的夫妇数据进行了分析。使用双变量和多变量逻辑回归模型，探讨了伴侣患有高血压的个体患高血压的可能性（492 对夫妇），以及伴侣患有高血压的个体高血压控制情况（121 对夫妇），即两名成员均患有高血压。为这两个研究问题分别建立了女性和男性的模型，以便对女性和男性的独立风险因素进行分析。
与伴侣没有高血压的个体相比，伴侣患有高血压的个体（男女）患高血压的未调整比值比为 1.57（95%CI 1.10-2.24），调整年龄、BMI、糖尿病、居住地点、个体和伴侣教育等因素后，女性的比值比为 1.35（95%CI 0.91-2.00），男性的比值比为 1.42（95%CI 0.98-2.07）。如果伴侣也患有控制良好的高血压，女性和男性控制自己的高血压的可能性显著增加，比值比分别为 3.69（95%CI 1.23-11.12）和 3.00（95%CI 1.07-8.36）。
在已婚纳米比亚成年人中，与患有高血压的伴侣生活在一起与高血压的发生呈正相关，尽管在调整后无统计学意义。伴侣的高血压控制与个体的高血压控制显著相关。可以在纳米比亚开展以夫妇为重点的干预措施，如对高血压患者的常规伴侣筛查。
