African American women have a higher prevalence of hypertension than women of other ethnicities. The increasing prevalence of hypertension among this population is alarming.
This was an 8-week feasibility study. The study population consisted of African American women aged 60 years and older with a self-reported diagnosis of hypertension. Participants identified a peer to participate with or were paired with another participant in the study. Educational sessions on communication, the Dietary Approaches to Stop Hypertension (DASH) diet, and home blood pressure monitoring were provided for participants. Participants were required to measure their blood pressure twice daily using an Omron monitor and communicate with their peers at least twice weekly. Dietary intake was measured pre- and post-intervention using the DASH Quality (DASH-Q) survey, social support was measured using the Medical Outcomes Study (MOS) Social Support Survey, and communication was tracked using communication logs. Feasibility was assessed by enrollment and retention rates.
Pre-intervention, participants had an average DASH-Q score of 33.76 (SD = 13.37). Participants' post-intervention DASH-Q scores increased by 5 points compared to their pre-intervention scores; however, this difference was not significant (t = -1.608, p = 0.059). Additionally, participants who completed the intervention had a 4-point decrease in their systolic blood pressure at week 6. A dependent sample t-test revealed the difference was significant (t = 2.305, p = 0.014). A total of 40 participants were enrolled in the study, and the retention rate was 85%.
Although not statistically significant, improvements in systolic blood pressure and DASH diet adherence were observed. Therefore, the results indicate that the peer (dyadic) support intervention was feasible.
非裔美国女性患高血压的比例高于其他种族的女性。该人群中高血压患病率的不断上升令人担忧。
这是一项为期8周的可行性研究。研究对象为60岁及以上自我报告患有高血压的非裔美国女性。参与者可自行选择一名同伴参与研究，或由研究人员将其与另一名参与者配对。为参与者提供了关于沟通、终止高血压膳食疗法（DASH饮食）和家庭血压监测的教育课程。参与者被要求使用欧姆龙血压计每天测量两次血压，并每周至少与同伴交流两次。干预前后使用DASH质量（DASH-Q）调查问卷测量饮食摄入量，使用医学结局研究（MOS）社会支持调查问卷测量社会支持，并使用沟通日志跟踪沟通情况。通过入组率和留存率评估可行性。
干预前，参与者的平均DASH-Q评分为33.76（标准差=13.37）。与干预前相比，参与者干预后的DASH-Q评分提高了5分；然而，这种差异并不显著（t=-1.608，p=0.059）。此外，完成干预的参与者在第6周时收缩压下降了4个点。相关样本t检验显示差异显著（t=2.305，p=0.014）。共有40名参与者入组该研究，留存率为85%。
尽管在统计学上不显著，但观察到收缩压和DASH饮食依从性有所改善。因此，结果表明同伴（二元）支持干预是可行
