Abstract

Hypertension is a severe medical condition and is the leading cause of premature death worldwide, significantly increasing the risk of heart, brain, kidney, and other diseases. However, not all people with hypertension are aware of their disease, and it is only discovered after complications occur. Therefore, hypertension must be prevented and controlled. Prevention and control of hypertension aims to prevent and reduce the probability of morbidity, complications, and death. Hypertension can be prevented by controlling risky behaviors. This study aims to analyze the risk factors for hypertension in coastal communities in Tarakan City. This research is quantitative research with a cross-sectional study design. The study sampled people in the working area of the Amal Beach Health Centre, Tarakan City, and met the sample criteria obtained using a purposive sampling technique. The data obtained will be processed univariate and bivariate. The results showed that there was a significant relationship between obesity (p-value 0.001), family history (p-value 0.013), and sports activity (p-value 0.009) with the incidence of hypertension. Smoking habits did not show a significant relationship (p-value 0.230) with the incidence of hypertension. This study concludes that obesity, family history, and exercise activity are risk factors for the incidence of hypertension in coastal areas of Tarakan City. Therefore, it is hoped that health promotion efforts in the form of scheduled counseling on risk factors for hypertension and preventive efforts in the form of early detection so that people can prevent or control hypertension to avoid complications.

Abstract

Relapsing Plasmodium vivax malaria remains a major obstacle to malaria elimination, with its treatment critically dependent on patient adherence to a 14-day primaquine regimen for radical cure. In hyperendemic regions like Papua, Indonesia, non-adherence is a primary cause of treatment failure. This study applied the Theory of Planned Behavior (TPB) to identify the key psychosocial determinants of adherence intention in this population to inform targeted public health interventions. A descriptive analytical study with a cross-sectional design was conducted in the East Sentani District of Papua, Indonesia, from February to April 2024. A total of 100 adult patients diagnosed with P. vivax malaria were recruited via consecutive sampling. A culturally adapted, validated questionnaire was used to measure the TPB constructs: attitude, subjective norms, and perceived behavioral control (PBC), alongside behavioral intention. Initial data analysis revealed quasi-complete separation, necessitating the use of a penalized logistic regression model (Firth's method) to generate stable and reliable estimates of association. The penalized logistic regression model was statistically significant and explained a considerable portion of the variance in adherence intention (Nagelkerke R² = 0.482). After controlling for other variables, a patient's personal attitude toward the treatment was the only significant predictor of their intention to complete the primaquine regimen. A more positive attitude was strongly associated with a higher intention to adhere (Odds Ratio [OR] = 5.21, 95% Confidence Interval [CI]: 2.15 - 12.67; p < 0.001). In contrast, neither subjective norms (OR = 1.12, 95% CI: 0.88 - 1.43; p = 0.354) nor perceived behavioral control (OR = 1.35, 95% CI: 0.91 - 2.01; p = 0.138) demonstrated a significant independent influence on behavioral intention. In conclusion, patient attitude—the individual's cognitive and affective evaluation of the treatment—is the primary driver of the intention to adhere to the 14-day primaquine regimen in this Papuan cohort. While social context and perceived barriers should not be disregarded, these findings strongly suggest that public health strategies must prioritize patient-centered educational interventions that cultivate a deep understanding of the biological necessity of radical cure to foster positive, resilient attitudes towards treatment completion.
