Item Risk factors for Pregnancy induced Hypertension(College of the Community Physicians of Sri Lanka, 2007) Perera, N.; Abeysena, C.OBJECTIVE: TO determine the risk factors for pregnancy induced hypertension (PIH). METHODOLOGY: The study was a case control study which was carried out at Castle Street Hospital for Women during August to September 2006. Hundred mothers newly diagnosed as having PlH. were Chosen as cases and 100 with uncomplicated pregnancies as controls. Both cases and controls had a period of amenorrhoea of >20 weeks. Psychosocial Stress was measured using General Health Questionnaire -30 (GHQ) and Modified Life Event inventory. Maternal socio-demographic information and other data were collected using an interviewer administered questionnaire and a record sheet. Multivariate logistic regression analysis was applied to control for confounders and the results were expressed as odds ratios (OR) and 95% confidence intervals (95%Cl). RESULTS: After adjusting for confounding effect experience of ≥2 life events during pregnancy (OR:2.1, 95%Cl:1.1 - 10.9), a maternal BMl of ≥26kg/m2 (OR:2.4, 95%Cl:1.1- 5.0), maternal age of ≥28 years (OR:3.9, 95%Cl:2.0-7.5), history of ante partum haemorrhage (OR:3.4, 95%Clz1.1 - 10.9) and standing for >1.5 hours at one stretch per day (OR:3.4, 95%Cl:1.6 - 7.4) had statistically significant associations with developing PlH. A GHQ score of >5 was not associated with PlH (OR:3.0, 95%Cl: 1.0 -10.0). CONCLUSION: Experience of 22 life events during pregnancy, BMl ≥26 kg/m2, maternal age of ≥28 years, history of antepartum haemoghage and standing for more than 1.5 hours at one stretch per day were risk factors for PlH.Item Compliance with antihypertensive medications and its associations and knowledge on Hypertension-Hospital based study in Sri Lanka(Sri Lanka College of Internal Medicine, 2019) Medagedara, A.U.; Thampoe, R.S.; Batagoda, B.M.S.M.; Mendis, W.A.S.; Martin, V.T.; Mettananda, K.C.D.BACKGROUND: Hypertension is the commonest preventable risk factor for the development of cardio and cerebrovascular disorders. Poor compliance with anti-hypertensive medications is an important yet often an under recognized risk factor for uncontrolled hypertension and rarely has this aspect been investigated thus far in Sri Lanka. OBJECTIVES: To determine the prevalence and associations of compliance with antihypertensive medications and the knowledge on hypertension among patients attending to medical clinics conducted by the Department of Medicine of the Faculty of Medicine, Ragama. METHODS: An interviewer-administered questionnaire and the patients' clinic records were utilized to collect data. Prevalence was assessed using SPSS 22 version. Associated factors were analyzed by binary logistic regression. RESULTS: Prevalence of medium and low compliance are 42.3% and 35.1% respectively. Factors significantly associated with poor compliance were not starting treatment at all due to the feeling that it's better not to start a treatment that they'll have to continue for the whole lifetime (p value 0.04), frequency at which medications have to be taken being too difficult to be followed (p value 0.00), finding it difficult to comprehend the instructions provided by the pharmacist (p value 0.00) and lack of knowledge on hypertension (p value 0.00). CONCLUSION: Compliance with antihypertensive medications can be enhanced by rectifying patients' misconceptions on hypertension.Item Validation of the World Health Organization/ International Society of Hypertension (WHO/ISH) cardiovascular risk predictions in Sri Lankans based on findings from a prospective cohort study(Ceylon College of Physicians, 2020) Thulani, U.B.; Mettananda, K.C.D.; Warnakulasuriya, D.T.D.; Peiris, T.S.G.; Kasturiratne, K.T.A.A.; Ranawaka, U.K.; Chackrewarthy, S.; Dassanayake, A.S.; Kurukulasooriya, S.A.F.; Niriella, M.A.; de Silva, S.T.; Pathmeswaran, A.P.; Kato, N.; de Silva, H.J.; Wickremasinghe, A.R.INTRODUCTION AND OBJECTIVES: There are no cardiovascular(CV)-risk prediction models specifically for Sri Lankans. Different risk prediction models not validated among Sri Lankans are being used to predict CV-risk of Sri Lankans. We validated the WHO/ISH (SEAR-B) risk prediction charts prospectively in a population-based cohort of Sri Lankans. METHOD: We selected participants between 40-64 years, by stratified random sampling of the Ragama Medical Officer of Health area in 2007 and followed them up for 10-years. Risk predictions for 10-years were calculated using WHO/ISH (SEAR-B) charts with- and without-cholesterol in 2007. We identified all new-onset cardiovascular events(CVE) from 2007-2017 by interviewing participants and perusing medical-records/death-certificates in 2017. We validated the risk predictions against observed CVEs. RESULTS: Baseline cohort consisted of 2517 participants (males 1132 (45%), mean age 53.7 (SD: 6.7 years). We observed 215 (8.6%) CVEs over 10-years. WHO/ISH (SEAR B) charts with and without-cholesterol predicted 9.3% (235/2517) and 4.2% (106/2517) to be of high CV-risk ≥20%), respectively. Risk predictions of both WHO/ISH (SEAR B) charts with- and without-cholesterol were in agreement in 2033/2517 (80.3%). Risk predictions of WHO/ISH (SEAR B) charts with and with out-cholesterol were in agreement with observed CVE percentages among all except in high risk females predicted by WHO/ISH (SEAR B) chart with-cholesterol (observed risk 15.3% (95% Cl 12.5 - 18.2%) and predicted risk 2::20%). CONCLUSIONS: WHO/ISH (SEAR B) risk charts provide good 10-year CV-risk predictions for Sri Lankans. The predictions of the two charts, with and without-cholesterol, appear to be in agreement but the chart with-cholesterol seems to be more predictive than the chart without-cholesterol. Risk charts are more predictive in males than in females. The predictive accuracy was best when stratified into two categories; low (<20%) and high (≥20%) risk.Item Epidemiology of hypertension in an urban Sri Lankan population(BMJ Publishing Group, 2011) Kasturiratne, A.; Warnakulasuriya, T.; Pinidiyapathirage, J.; Kato, N.; Wickremasinghe, A.R.; Pathmeswaran, A.INTRODUCTION: Hypertension is a common risk factor for cardiovascular disease. In Sri Lanka, despite the existence of a universal free health system, services are not available for routine screening of hypertension in the general population. This paper aims to describe the epidemiology of hypertension in 35–64 year old residents in Ragama Medical Officer of Health area in the Gampaha district, Sri Lanka. METHODS: An age-stratified random sample of 4400 adults between 35 and 64 years of age drawn from the population based electoral list, was invited for a screening programme on cardiovascular risk factors. Socio-demographic and risk factor related data and anthropometric and blood pressure measurements were obtained by trained research assistants. Blood was obtained for relevant biochemical investigations. RESULTS: The prevalence of hypertension (systolic >139 mm Hg and/or diastolic >89 mm Hg) in 2986 subjects (Males 45%), was 30.4% (27.8% in males; 32.5% in females). 31.8% (n=288) were previously undetected. Of the known hypertensives, 19.5% were not on anti-hypertensive medication and only 32.1% were controlled (defined by systolic <140 mm Hg and diastolic <90 mm Hg). Factors associated with hypertension in both males and females were body mass index, waist circumference, fasting blood glucose and serum triglycerides. CONCLUSIONS: The prevalence observed is comparable to the prevalences of developed countries with relatively older populations. A considerable proportion of known hypertensives are not on treatment and the observed poor control indicates problems in drug compliance. Interventions targeting lifestyle modification and drug compliance are essential to control adverse outcomes of hypertension.
