:In China, there are approximately 250 million adults who have hypertension with low rates of awareness, treatment and control. Changes in lifestyles at a population level have the potential to enhance or deteriorate the prevention and control of hypertension. We used data from a regional hypertension survey to examine the impact of 2/1 mm Hg decreases or increases in population blood pressure on hypertension prevalence, and rates of unawareness of the hypertension diagnosis, treatment, and control. The primary analysis was based on the average blood pressure of respondents from three visits and a diagnostic threshold of 140/90 mm Hg for hypertension. Secondary analyses examined average blood pressure from the first survey visit and also a diagnostic threshold of 130/80 mm Hg for hypertension. The baseline hypertension prevalence was 33.4%, and rates of unawareness of the hypertension diagnosis, treatment, and control were 74.2%, 25.8%, and 9.7%, respectively. Decreases or increases in blood pressure by 10/5 mm Hg resulted in changes in hypertension prevalence (22.1% vs 53.4%) and rates of unawareness of the diagnosis (60.9% vs 83.8%), treatment (39.1% vs 16.2%), and control (21.2% vs 3.6%), respectively. Similar trends were seen in the secondary analyses. Population changes in lifestyle could have a very large impact on the prevalence and control of hypertension in China. The results support implementation of programs to improve population lifestyles while implementing health services policies to enhance the clinical management of hypertension.


在中国,大约有 2.5亿成年人患有高血压,知晓率、治疗率和控制率较低。在人口水平上生活方式的改变有可能增强或恶化高血压的预防和控制。我们使用来自地区高血压调查的数据来检查人群血压降低或升高 2/1mm Hg 对高血压患病率的影响,以及对高血压诊断、治疗、和控制。主要分析基于三次就诊的受访者的平均血压和高血压的诊断阈值为 140/90mm Hg。二次分析检查了第一次调查访视的平均血压,以及高血压的诊断阈值为 130/80mm Hg。基线高血压患病率为 33.4%,对高血压的诊断、治疗和控制不知晓率分别为 74.2% 、 25.8% 和 9.7%。血压降低或升高 10/5mm Hg 导致高血压患病率 (22.1% vs 53.4%) 和对诊断的不知晓率 (60.9% vs 83.8%) 发生变化, 治疗 (39.1% vs 16.2%) 和对照 (21.2% vs 3.6%)。在次要分析中观察到类似的趋势。人群生活方式的改变可能对中国高血压的患病率和控制产生非常大的影响。结果支持实施改善人口生活方式的方案,同时实施卫生服务政策,以加强高血压的临床管理。

METHODS:BACKGROUND:Hypertensive disorders of pregnancy (HDP) increase cardiovascular disease (CVD) risk. Pregnancy morbidities, including preeclampsia, and CVD are common in systemic lupus erythematosus (SLE). Possible connections are important to explore. In a population-based cohort, we investigated whether HDP is associated with a higher risk of cardiovascular outcomes separately in SLE and non-SLE to examine the role of SLE. METHODS:We identified first singleton births in the Medical Birth Register (1987-2012) among mothers with SLE and a large general population comparison group. Discharge diagnoses for HDP, cardiovascular outcomes, and hypertension in the Patient Register were identified using ICD codes. We estimated adjusted hazard ratios and 95% confidence intervals (HR, 95% CI) of the association between HDP and outcomes, in separate models in women with and without SLE. We then evaluated additive and multiplicative effect modification using relative excess risk due to interaction and Cox models jointly accounting for SLE and HDP, respectively. Mediation analysis estimated the proportion of the association between SLE and outcome explained by HDP. RESULTS:HDP were more common in SLE pregnancies (20% vs 7%). In SLE, HDP were associated with a two-fold higher rate of cardiovascular outcomes and three-fold higher rate of incident hypertension. HDP mediated 20% of the latter association. In women without SLE, HDP was associated with higher hypertension incidence later in life. CONCLUSION:In women with and without SLE, HDP were associated with a three-fold higher rate of hypertension. In SLE, women with HDP developed cardiovascular outcomes twice as often as women without HDP.

METHODS:BACKGROUND:'Neuronal precursor cell expressed developmentally down-regulated 4-like' (NEDD4L) is considered a candidate gene for hypertension-both functionally and genetically-through the regulation of the ubiquitination of the epithelial sodium channel (ENaC). This study explores the relationship between genetic variation in NEDD4L and hypertension with chronic kidney disease (CKD) in the southeastern Han Chinese population. METHODS:We recruited 623 CKD patients and measured ambulatory blood pressure monitoring (ABPM), and the rs4149601 and rs2288774 polymorphisms in NEDD4L were genotyped using qPCR. RESULTS:For rs4149601, significant differences in genotype frequencies in an additive model (GG vs GA vs AA) were observed between normotensive patients and hypertensive patients when hypertension was classified into ambulatory hypertension, clinical hypertension and ambulatory systolic hypertension (P = 0.038, 0.005 and 0.006, respectively). In a recessive model (GG+GA vs AA), the frequency of the AA genotype of rs4149601 in the hypertension groups were all higher than that in the normotensive groups. The genotype distribution of rs2288774 did not differ significantly between the normotensive and hypertensive patients. In both the full cohort and the propensity score matching (PSM) cohort, the AA genotype of rs4149601 (compared to the GG+GA genotype group) was independently correlated with ambulatory hypertension, clinical hypertension and ambulatory systolic hypertension by multivariate logistic regression analysis. CONCLUSIONS:The present study indicates that the AA genotype of rs4149601 associates with hypertension in CKD. Consequently, the rs4149601 A allele might be a risk factor for hypertension with CKD.

METHODS:BACKGROUND:The burden of hypertension in many low-and middle-income countries is alarming and requires effective evidence-based preventative strategies that is carefully appraised and accepted by key stakeholders to ensure successful implementation and sustainability. We assessed nurses' perceptions of a recently completed Task Shifting Strategy for Hypertension control (TASSH) trial in Ghana, and facilitators and challenges to TASSH implementation. METHODS:Focus group sessions and in-depth interviews were conducted with 27 community health nurses from participating health centers and district hospitals involved in the TASSH trial implemented in the Ashanti Region, Ghana, West Africa from 2012 to 2017. TASSH evaluated the comparative effectiveness of the WHO-PEN program versus provision of health insurance for blood pressure reduction in hypertensive adults. Qualitative data were analyzed using open and axial coding techniques with emerging themes mapped onto the Consolidated Framework for Implementation Research (CFIR). RESULTS:Three themes emerged following deductive analysis using CFIR, including: (1) Patient health goal setting- relative priority and positive feedback from nurses, which motivated patients to make healthy behavior changes as a result of their health being a priority; (2) Leadership engagement (i.e., medical directors) which influenced the extent to which nurses were able to successfully implement TASSH in their various facilities, with most directors being very supportive; and (3) Availability of resources making it possible to implement the TASSH protocol, with limited space and personnel time to carry out TASSH duties, limited blood pressure (BP) monitoring equipment, and transportation, listed as barriers to effective implementation. CONCLUSION:Assessing stakeholders' perception of the TASSH implementation process guided by CFIR is crucial as it provides a platform for the nurses to thoroughly evaluate the task shifting program, while considering the local context in which the program is implemented. The feedback from the nurses informed barriers and facilitators to implementation of TASSH within the current healthcare system, and suggested system level changes needed prior to scale-up of TASSH to other regions in Ghana with potential for long-term sustainment of the task shifting intervention. TRIAL REGISTRATION:Trial registration for parent TASSH study: NCT01802372. Registered February 27, 2013.
