Item Prevalence of hypertension in a rural district of Sri Lanka(Sri Lanka Medical Association, 2017) Luke, W.A.N.V.; Ediriweera, D.S.; de Silva, K.C.; Balasooriya, E.R.; Perera, K.M.N.; Ranasinha, C.D.; Kasturiratne, A.; de Silva, H.A.INTRODUCTION & OBJECTIVES: Hypertension is a leading cause of cardiovascular morbidity and mortality. Data on prevalence of hypertension in rural settings of Sri Lanka is limited. We conducted a study to determine the prevalence of hypertension among adults over 40 years of age in the Puttalam district.METHODS: A community-based prevalence study was conducted in selected Grama Niladhari divisions in ten Medical Officer of Health areas in the Puttalam district. Adults over 40 years of age living in consecutive households were screened by trained research assistants using digital blood pressure (BP) meters. Basic demographic data were obtained using an intervieweradministered questionnaire. Previously undiagnosed adults with persistent elevation of BP (SBP > 140 and /or DBP > 90 mmHg on two readings) and those already on treatment for hypertension were identified. RESULTS: A total of 2289 were screened. The mean (SD) of SBP and DBP were 134.5(21.3) and 82.1 (13.5) mmHg respectively. The overall hypertension prevalence was 458.5 (95% CI 438.1– 478.8) per 1000 population. 16.3% were newly diagnosed. Prevalence of uncontrolled hypertension among those on treatment was 516.2 (95% CI 479.4–552.9) per 1000. 98.7 (95% CI 86.6–110.9) per 1000 had blood pressure >160/110 mmHg. There was an increasing trend in blood pressure with increasing age (OR=1.07, 95% CI 1.06–1.08, p<0.01) but not with the male sex. CONCLUSION: Prevalence of hypertension is high in this rural adult cohort. Previously undetected hypertension and uncontrolled hypertension among those already on treatment are common. Community-based approaches targeting screening and BP control are essential to reduce adverse outcomes of hypertension.Item Prevalence of hypertension and its risk factors among estate workers in the Medical Officer of Health area, panvila, in the district of Kandy(Sri Lanka Medical Association, 2017) Aththaragama, A.S.I.; Kasturiratne, A.INTRODUCTION & OBJECTIVES: Hypertension is the leading modifiable risk factor of cardiovascular diseases. The prevalence of hypertension differs across countries, geographical areas and social strata. The objective was to determine the prevalence of hypertension and its associated factors among estate workers in the Panvila MOH area in the Kandy district. METHODS: A cross-sectional analytical study was conducted among randomly selected 411 estate workers between 30-59 years of age from eight estates within the Panvila MOH area. Screening was done in collaboration with the Office of the Medical Officer of Health, Panvila. After informed consent, blood pressure and anthropometric measurements were obtained. An interviewer-administered questionnaire was used to obtain data on risk factors. RESULTS: Of the sample, 36.2% were males and 95% were Tamils. The crude prevalence of hypertension was 24.6% and age-adjusted prevalence rates were 272 and 245 per 1000 population for males and females, respectively. More than 80% of the hypertensives were previously undiagnosed. Only 23% of diagnosed hypertensives were on treatment. About 27% of the participants had a BMI ≥23 kg/m2. 99% were highly physically active. The daily salt consumption was higher than the recommended amount in 90%. Dysglycaemia was present in 3.5%. Age, ethnicity, dysglycaemia and high salt consumption were associated significantly with hypertension in the bi-variate analysis. Advancing age group was the only independent predictor of hypertension in the multivariate analysis. CONCLUSION: Nearly 25% of the estate workers are hypertensive. Undetected hypertension is common and compliance with treatment is poor. These findings will be important for planning and implementing targeted interventions.
