BACKGROUND & OBJECTIVES: There are no composite estimates on prevalence of hypertension among indigenous tribes in India. The present study was carried out to estimate the prevalence of hypertension, its association with determinants, and to assess the hypertension related behaviour of the Nicobarese aborigines.
METHODS
This cross-sectional survey was carried during 2007 and 2009. Subjects were chosen by two stage design. Total 975 subjects of 1270 (response rate of 76.8%) were investigated (M: 43.5%; F: 56.5%). The data were collected by history, clinical examination (blood pressure), and examination (weight and height). The association of hypertension with age, education, tobacco, alcohol consumption and their dependency status (KF score, QF value, and AUDIT score) and nutritional status was estimated by bivariate regression analysis; the increasing trend in the prevalence of hypertension with increasing age and decreasing educational status was analysed by χ2 for linear trend. Significant variables in bivariate regression analysis (age, education, alcohol consumption status, and nutritional status) were subjected to multiple logistic regression analysis (MLR).
RESULTS
The prevalence of hypertension was 50.5 per cent [95% CI 46.1-54.9 (M: 50.7%; F: 50.3%)]. The prevalence of tobacco, alcohol consumption, and overweight/obesity was 88, 54, and 37 per cent respectively. The bivariate analysis has shown association between hypertension and age, education subcategories, alcohol consumption, and overweight/obesity (P<0.05). The increasing trend in the prevalence of hypertension with increasing age (χ2 for linear trend=95.88, P< 0.001) and decreasing educational status (χ2 for linear trend=25.55, P< 0.001) was statistically significant. MLR analysis revealed a significant association between hypertension and various age categories and overweight/obesity.
INTERPRETATION & CONCLUSIONS: The findings of the present study highlight high prevalence of hypertension among Nicobarese aborigenes.
背景与目的
目前尚无关于印度土著部落人群高血压患病率的综合估计数据。本研究旨在评估高血压的患病率，及其与各种决定因素的关联，并评估尼科巴群岛原住民的高血压相关行为。
方法
本横断面研究于 2007 年至 2009 年进行。采用两阶段设计选择研究对象。共调查了 1270 名受试者中的 975 名（应答率为 76.8%）（男性占 43.5%，女性占 56.5%）。通过病史、临床检查（血压）和检查（体重和身高）收集数据。采用双变量回归分析评估高血压与年龄、教育程度、烟草、酒精消费及其依赖状态（KF 评分、QF 值和 AUDIT 评分）和营养状况的关联；采用线性趋势 χ2 检验分析高血压患病率随年龄增加和教育程度降低的变化趋势。将双变量回归分析中的显著变量（年龄、教育程度、酒精消费状况和营养状况）纳入多因素逻辑回归分析（MLR）。
结果
高血压的患病率为 50.5%[95%CI 46.1-54.9（男性：50.7%；女性：50.3%）]。烟草、酒精消费和超重/肥胖的患病率分别为 88%、54%和 37%。双变量分析显示，高血压与年龄、教育程度亚组、酒精消费和超重/肥胖相关（P<0.05）。高血压患病率随年龄增加（线性趋势 χ2=95.88，P<0.001）和教育程度降低（线性趋势 χ2=25.55，P<0.001）呈上升趋势，且具有统计学意义。MLR 分析显示，高血压与各年龄段和超重/肥胖之间存在显著关联。
结论
本研究结果表明，尼科巴群岛原住民的高血压患病率较高。
