The relationship between social support and hypertension is poorly understood in women and men. We investigated whether multiple measures of social support are linked to blood pressure levels differentially by gender.
Cross-sectional study of 28,779 middle-age and older-age adults (45-85 years) in the baseline Canadian Longitudinal Study on Aging comprehensive cohort. Stratified multivariable regression models estimated the role and relative contribution of 4 types of support to blood pressure in women and men.
The highest levels of perceived availability of informational, tangible, emotional, and belonging support were significantly associated with the lowest mean level of systolic blood pressure (SBP) but not diastolic blood pressure, independent of known confounders and other support types. However, associations were small, and their directions were more consistent in women. The lowest levels of informational support, relative to the highest, were associated with higher odds of hypertension in women (odds ratio [OR] = 1.20 [95% confidence interval {CI}: 1.06, 1.36]), more so than in men (OR = 1.16 [95% CI: 1.03, 1.32]). The lowest levels of emotional support were similarly associated with the odds of hypertension (OR = 1.08 [95% CI: 1.00, 1.17] in women and OR = 1.08 [95% CI: 1.00, 1.15] in men), relative to the highest. Larger differences in mean SBP in women, compared with men, were seen for informational support (2.43 and 1.18 mm Hg, respectively) and emotional support (1.60 and 0.74 mm Hg, respectively). Findings were unaltered by sensitivity analyses.
Informational and emotional support were inversely associated with SBP, more so in women than men. Further longitudinal investigation is warranted, as results suggest that specific supports may help prevent hypertension and lower cardiovascular risk, especially in women.
社会支持与高血压之间的关系在男性和女性中都未得到充分理解。我们调查了多种社会支持措施是否因性别不同而与血压水平存在差异关联。
对加拿大老龄化纵向研究综合队列基线中的28779名中老年人（45 - 85岁）进行横断面研究。分层多变量回归模型估计了四种支持类型对男性和女性血压的作用及相对贡献。
信息支持、实际支持、情感支持和归属感支持的最高感知可得水平与收缩压（SBP）的最低平均水平显著相关，但与舒张压无关，且独立于已知混杂因素和其他支持类型。然而，关联较小，且在女性中方向更一致。相对于最高水平，信息支持最低水平与女性高血压几率较高相关（比值比[OR]=1.20[95%置信区间{CI}：1.06，1.36]），男性中则为（OR = 1.
