Hypertension remains a major public health concern, including among the productive-age population. This study aimed to analyze factors associated with hypertension among individuals of productive age in the working area of Sematang Borang Public Health Center, Palembang City, in 2026. A quantitative observational study with a cross-sectional design was conducted among a population of 2,818 individuals aged 15–64 years. A total of 143 respondents were selected using accidental sampling. Data were collected through structured questionnaires, the Food Frequency Questionnaire (FFQ), International Physical Activity Questionnaire (IPAQ), and Perceived Stress Scale (PSS-10). Data analysis included univariate analysis, Chi-square tests, and multiple logistic regression at a 95% confidence level. The results showed that 58.0% of respondents had hypertension. Significant associations were identified between hypertension and age (p<0.001), sex (p=0.025), fast-food consumption (p<0.001), Body Mass Index (p=0.004), smoking habits (p=0.005), physical activity (p=0.022), stress levels (p=0.014), occupation (p=0.001), and sodium intake (p<0.001). Multivariate analysis identified sodium intake as the dominant associated factor (OR=4.021). In conclusion, hypertension among productive-age individuals was associated with multiple demographic and behavioral factors, particularly sodium intake. Preventive strategies should prioritize sodium reduction, healthier dietary habits, regular physical activity, weight management, smoking cessation, stress management, and early hypertension screening through primary healthcare services.
