Hypertension is a potential risk factor for cardiovascular diseases. With increasing age there is differential rise of systolic and diastolic blood pressure leading to development of various hypertension subtypes which have its own clinical implications. Present study assessed distribution and risk factors of hypertensive subtypes in the hill tribe of Mizoram.
The present study was a community-based cross-sectional study carried out in Aizawl, Mizoram representing both rural (fourteen villages) and urban (six wards) population and which were selected by PPS method. Individuals aged 18 years and above providing informed verbal consent were included for collection of sociodemographic and clinical data including blood pressure. Of the total 12,313 subjects (Urban: 5853, Rural: 6460) & (Male: 5459, Female: 6854) surveyed, 549 hypertensive subjects who were under antihypertensive treatment were excluded. Hypertension subtype was defined as per standard guidelines.
Out of 11,764 study individuals, 88.03% (CI: 87.43-88.61) were normotensive and 11.97% (CI: 11.39-12.57) individuals were hypertensive. Prevalence of ISH, IDH and SDH were 241(2.05%), 403 (3.43%) and 764 (6.49%) respectively. Older age, unmarried participants, physical inactivity and obesity are found to be associated with ISH. Male gender, older age, higher educational status, physical inactivity, consumption of extra salt, alcohol consumption, use of tuibur and high BMI were significantly associated with SDH.
The overall prevalence of hypertension with its subtypes specifically isolated systolic hypertension are low in this hill tribe of Mizoram. It is the right time for initiating intervention programme to modify the risk factors associated with hypertension.
高血压是心血管疾病的潜在危险因素。随着年龄的增长，收缩压和舒张压会出现不同程度的升高，导致各种高血压亚型的发展，这些亚型具有各自的临床意义。本研究评估了米佐拉姆邦山区部落人群中高血压亚型的分布和危险因素。
本研究是一项在米佐拉姆邦首府艾藻尔进行的基于社区的横断面研究，代表了农村（14 个村庄）和城市（6 个区）人群，采用 PPS 方法选择。纳入了年龄在 18 岁及以上、提供口头知情同意的个体，收集社会人口学和临床数据，包括血压。在总共调查的 12313 名个体中（城市：5853 人，农村：6460 人；男性：5459 人，女性：6854 人），排除了 549 名正在接受降压治疗的高血压患者。根据标准指南定义高血压亚型。
在 11764 名研究个体中，88.03%（置信区间：87.43-88.61）为正常血压，11.97%（置信区间：11.39-12.57）为高血压患者。ISH、IDH 和 SDH 的患病率分别为 241（2.05%）、403（3.43%）和 764（6.49%）。年龄较大、未婚、缺乏体力活动和肥胖与 ISH 相关。男性、年龄较大、较高的教育程度、缺乏体力活动、额外摄入盐、饮酒、使用 tuibur 和高 BMI 与 SDH 显著相关。
在这个米佐拉姆邦的山区部落中，高血压及其亚型的总体患病率较低，特别是孤立性收缩期高血压。现在是时候启动干预计划，以改变与高血压相关的危险因素了。
