Abstract

Hypertension is a major global public health concern associated with increased risk of cardiovascular morbidity and mortality. Despite the availability of effective antihypertensive therapy, suboptimal blood pressure control remains prevalent, particularly in low- and middle-income countries. Poor medication adherence is a key contributing factor, often influenced by various sociodemographic and clinical characteristics. This study aimed to assess the level of medication adherence among hypertensive patients and to examine the association between sociodemographic and clinical factors and adherence behavior in an urban Indonesian population. A cross-sectional study was conducted among 153 hypertensive patients attending six public health centers in Medan City, Indonesia, between August and October 2021. Participants were selected using purposive sampling. Medication adherence was assessed using the validated Indonesian version of the Eight-Item Morisky Medication Adherence Scale (MMAS-8). Data on age, education, income, family history, body mass index, comorbidities, and blood pressure were collected through interviews and direct measurements. Bivariate and multivariate logistic regression analyses were performed using SPSS version 24.0 to identify significant predictors of adherence. Among the participants, 52.3% demonstrated high medication adherence, while 47.7% had low adherence. Multivariate analysis revealed that age ≥45 years (RP = 4.29; p = 0.023), low education level (RP = 1.50; p = 0.044), and family history of hypertension (RP = 2.05; p = 0.040) were significantly associated with adherence. Other variables, including income, BMI, and comorbidities, were not significant predictors. Medication adherence among hypertensive patients remains suboptimal. Targeted interventions focusing on older adults, patients with lower education, and family-centered support may enhance adherence and improve hypertension management outcomes.

Abstract

High blood pressure, or hypertension, is a worldwide health issue. The prevalence of hypertension is still high today. However, there are no established risk factors for hypertension. The purpose of this study was to identify risk factors for hypertension. This study used a cross-sectional design and was observational. The sample included 200 recruits that were purposively selected from 4 subdistricts in Medan city. Data were collected through interviews and made measurements. Data were analyzed using simple and multiple logistic regression. Prevalence of high blood pressure was 59.0%, consisting of pre hypertension at 24.5% and hypertension at as much as 34.5%. The majority of respondents were aged 45 years or younger (66.0%), 185 were female (92.5%), 124 were low income (62.0%), 143 had no family history (71.5%), 95 were overweight (47.5%), 137 were normal blood glucose, 183 had no smoking habit (91.5%), and 134 were physically inactive (67,0%). The Multiple Logistic regression showed that age, Basal metabolic index, daily vegetables, and fruit consumption are significant factors that contribute to high blood pressure in the community in Medan City. Age, BMI and daily vegetables and fruit consumption are significant factors with high blood pressure among community. Intervention programs should be primarily focused on risk factors such as losing weight and maintaining an ideal body weight and implementing healthy lifestyle.

Abstract

Background: Prehypertension and hypertension are serious public health issues that are frequently disregarded. The condition is linked to morbidity and is known to increase the risk of kidney, cardiovascular, and cerebrovascular illness. Objectives: The objective of this study was to determine the prevalence of pre hypertension and hypertension and factors associated among the adult population Settings and Design: This was an observational study with cross sectional design. Methods and Materials: The sample included 200 recruits from 4 subdistricts in Medan city that selected using purposive sampling. Data were collected by interviews and measurements. Statistical analysis: Data were analyzed using multiple logistic regression. Results: Prevalence of hypertension as 24.5% an hypertension as much as 34.5%. The majority of respondents were aged 45 years or younger (66.0%), 185 were female (92.5%), 124 were low income (62.0%), 143 had no family history (71.5%), 95 were overweight (47.5%), 137 were normal blood glucose, 183 had no smoking habit (91.5%), and 134 were physically inactive (67,0%). Of the Multiple Logistic regression showed that Basal metabolic index and daily vegetables and fruit consumption are significant factors contribute to prehypertenion, while age, Basal metabolic index and daily vegetables and fruit consumption are significant factors contribute to hypertension among adult population in Medan City. Conclusions: BMI and daily vegetables and fruit consumption are signifant factors to pre hypertension, while BMI and daily vegetables and fruit consumption are significant factors to hypertension among adult population. Intervention programs should be primarily focused on the risk factors such as losing weight and maintaining an ideal body weight and implementing healthy lifestyle. Keywords:  Pre Hypertension, Hypertension, Prevalence, Determinant.

Abstract

The global rise in the prevalence of type 2 diabetes is heavily concentrated in urban centers, yet more than half of those affected remain completely undiagnosed. Non-invasive clinical risk assessment tools can indeed stratify population risk, but there remains a gap in operational validation regarding the Finnish Diabetes Risk Score (FINDRISC) when combined with biochemical verification in urban populations in Indonesia. This study evaluated the diagnostic accuracy of the FINDRISC questionnaire in identifying undiagnosed type 2 diabetes and dysglycemia, using the oral glucose tolerance test (OGTT) as the gold standard. The study was conducted in the community using a cross-sectional design with non-random, purposive sampling in six subdistricts to recruit 300 adults aged 30–75 years. The 8-item FINDRISC questionnaire and anthropometric measurements were administered, followed by biochemical verification via OGTT and chi-square analysis. FINDRISC categorized 33.7% of participants as low-risk and 5.3% as high-risk, while the OGTT confirmed 18.0% had prediabetes and 30.0% had diabetes. Increased risk was significantly correlated with advanced age, high body mass index (BMI), central obesity, lack of physical activity, inadequate fruit and vegetable intake, treatment for hypertension, a history of hyperglycemia, and family predisposition (p<0.005). Among low-risk respondents, 68.3% had normal glucose levels, whereas 61.8% of high-risk individuals had glucose levels indicative of diabetes (p<0.005). The integration of the non-invasive FINDRISC triage tool prior to laboratory testing offers a resource-efficient sequential screening framework for urban primary health care. This strategy optimizes the allocation of institutional resources, detects subclinical dysglycemia early, and enables targeted preventive lifestyle interventions.Keywords: Type 2 Diabetes, FINDRISC, Oral Glucose Tolerance Test, Mass Screening, Public Health Surveillance.
