Prevalence of Hypertension in Semi-Urban area of Nepal

Abstract

Hypertension is one of the major cardiovascular problems in middle and low income countries. There are few studies conducted in Nepal which shows significant number of hypertensive popu­lation in suburban area. Systematic random sampling from voter lists of all the members more than 18 years of age of Dhulikhel Municipality was done. 796 among 1150 sampled population were interviewed and their blood pressure was measured twice using mercury sphygmomanom­eter in standard method in their home. The average blood pressure was taken for study. Hyper­tension was defined as systolic blood pressure ≥ 140 mmHg and/or diastolic blood pressure ≥ 90 mmHg, and/or on antihypertensive treatment. Total number of study population was 796. Among them 490 (61.6%) were female and 306 (38.4%) were male with age ranging from 18 years to 88 years (mean 48.41±17.38). Overall prevalence of hypertension was 28.9% (male 28.8%, female 29%). The prevalence was increasing with age (11.1% in <30 years to 44.8% in >70 years). Ac­cording to JNC 7, 29.1% were in Pre-hypertensive group. This study shows that Hypertension is significant in suburban area of Nepal.

Prevalence of hypertension and its associated risk factors in a sub-urban area of central Nepal

“…These associations are well established in various studies conducted at national and international level. 9,10,12,25,[27][28][29][30][31][32][33] Hypertension prevalence increased with advancing age (Table 1) in this study which is consistent with findings from number of other studies. [27][28][29][30][31][32][33] Majority of the respondents (152) in this study were female.…”

[27][28][29][30][31][32][33] Majority of the respondents (152) in this study were female. This may be because, male population were not available at the time of data collection as they were out of the house for their job, while majority of the female population were homemaker, and were available at the time of data collection.…”

“…32 Interestingly, in a study by Manandhar et al high prevalence of hypertension was found to be in non-smokers group in comparison to smokers group though the groups were not statistically significant (p=0.196). 9 Increased salt intake more than 5 gram/day is another crucial risk factor of hypertension which has been reported in some studies.…”

“…10,11,29,30,32,37 Compared to normotensive, studies have depicted that hypertensive subjects were more likely to have diabetes. 10,11 Consistently, this study showed a strong association between diabetes and hypertension (p= 0.026).…”

Prevalence and Awareness of Hypertension among Adults and its Related Risk Factors

“…17 Among 215 participants having high blood pressure currently, 80 (37.20%) were not aware that they have high BP. The data is higher in compare to the 7th Report of the JNC on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure which stated it was approximately 30 percent 2 and is much less than a study of Dhulikhel that showed 69.9% of hypertensive were unaware of their hypertensive status 14 and almost similar (39.1%) to a study of city malls in Kathmandu that showed only 39.13%.…”
