Abstract

Background Pulmonary tuberculosis (TB) remains a persistent public health concern in Indonesia, driven by a complex interplay of individual and environmental risk factors. Understanding these determinants is crucial to enhance disease control strategies at the community level. Objective This study aimed to analyze the risk factors associated with the incidence of pulmonary tuberculosis in the working area of Tebing Tinggi Public Health Center, Empat Lawang. Methods A quantitative cross-sectional study was conducted involving 76 respondents selected from 321 suspected TB patients using purposive sampling. Data were collected using structured questionnaires. Bivariate analysis was performed using the Chi-Square test, and multivariate analysis was conducted using logistic regression to determine the dominant risk factors. Results Bivariate analysis showed that age (p = 0.04) and household contact (p = 0.00) were significantly associated with the incidence of pulmonary TB, while gender, knowledge, housing density, and ventilation were not (p > 0.05). Multivariate analysis revealed that household contact was the most dominant factor influencing TB incidence. Conclusion Household contact and older age were significantly associated with pulmonary tuberculosis incidence. Targeted interventions such as household contact tracing and focused health education for older populations are essential to reduce transmission and improve TB control at the community level.

Abstract

Background Tuberculosis (TB) remains a major global health problem with high rates of morbidity and mortality, particularly in developing countries like Indonesia. One of the main challenges in TB control is the low treatment adherence among patients undergoing long-term therapy. Objective This study aimed to analyze the factors influencing tuberculosis medication adherence among patients at Lesung Batu Community Health Center.. Methods A quantitative cross-sectional study was conducted from May 8 to 27, 2025, involving 56 TB patients registered at the Lesung Batu Health Center. Total sampling was used. Data were collected using a structured questionnaire based on the Morisky Medication Adherence Scale (MMAS-8) and analyzed using Chi-square and multivariate logistic regression. Results Only 51.8% of respondents were adherent to TB medication. Bivariate analysis showed that gender (p=0.01), distance to health facilities (p=0.01), and family support (p=0.00) had significant associations with adherence. Multivariate analysis revealed family support as the most dominant factor (OR=0.16, 95% CI=0.05–0.51), indicating that patients without family support were 6.25 times more likely to be non-adherent. Conclusion Family support, proximity to health services, and male gender significantly influenced TB medication adherence. Interventions should focus on increasing family involvement and improving access to care for patients in remote areas. Primary healthcare providers are advised to implement community-based strategies that include home visits, family counseling, and cross-sectoral collaboration to enhance adherence and improve treatment outcomes.

Abstract

Background Hypertension is one of the leading non-communicable diseases with increasing prevalence, including among the productive age group. Several risk factors such as age, occupation, body weight, family history, smoking habits, physical activity, and fruit and vegetable consumption are suspected to influence the incidence of hypertension. Objective This study aimed to analyze the factors affecting the incidence of hypertension among productive age individuals in the working area of Muara Beliti Public Health Center in 2025. Methods This was a quantitative study using a cross-sectional approach. A total of 93 respondents aged 16–64 years were selected using purposive sampling. Data were collected through questionnaires and medical records, then analyzed using Chi-Square and multivariate logistic regression tests. Results The results showed significant relationships between age (p=0.031), body weight (p=0.001), smoking habits (p=0.030), physical activity (p=0.016), and fruit and vegetable consumption (p=0.011) with the incidence of hypertension. No significant relationship was found between occupation and family history with hypertension. Multivariate analysis revealed that physical activity was the most dominant factor (p=0.002; OR=4.80; 95% CI=1.80–12.80). Conclusion Physical activity is the most dominant factor influencing the incidence of hypertension among the productive age population.Health interventions should prioritize increasing physical activity, promoting healthy eating habits, and controlling other risk factors to reduce the incidence of hypertension among productive age individuals.

Abstract

Background: The Intrauterine Device (IUD) is one of the most effective long-acting reversible contraceptives, yet its utilization remains low in Indonesia, including at Gumawang Community Health Center, Ogan Komering Ulu Timur District. Predisposing factors such as knowledge, beliefs, and cultural perceptions are believed to contribute to the low uptake of IUDs. Objective: This study aimed to analyze the factors influencing IUD use among women of reproductive age. Methods: A qualitative study with a phenomenological approach was conducted to explore participants’ experiences and perceptions. Data were collected through in-depth interviews and focus group discussions (FGDs) involving 17 informants, including IUD acceptors, non-IUD acceptors, unmet need groups, health workers, and family planning program officers. Data analysis employed reduction, data presentation, and conclusion drawing, supported by source triangulation to ensure trustworthiness. Results: Three major themes emerged: (1) knowledge—variations in understanding IUD definition, duration, benefits, and side effects; (2) beliefs—dominated by fear, shame, and mixed religious views; and (3) culture—community myths and narratives surrounding IUD safety that shape perceptions negatively. These findings demonstrate that misinformation and limited exposure strongly influence decision-making regarding IUD adoption. Conclusion: Knowledge, beliefs, and cultural perceptions significantly affect women’s decisions to use IUDs. Strengthening health education, counseling, and partnerships with community and religious leaders is essential to counter misinformation and improve IUD acceptance.

Abstract

Background: Patient satisfaction is a key indicator for evaluating the quality of health care services. Various factors can influence patient satisfaction, ranging from demographic characteristics to attributes of public service delivery. However, studies on patient satisfaction in the Internal Medicine Outpatient Clinic at Kepahiang District General Hospital remain limited. Objective: This study aimed to analyze the factors associated with the level of patient satisfaction with services in the Internal Medicine Outpatient Clinic at Kepahiang District General Hospital in 2025. Methods: This research employed a quantitative analytic design with a cross-sectional approach. A total of 98 respondents were selected through purposive sampling. Data were collected using a structured questionnaire that had been tested for validity and reliability. Data analysis included chi-square tests for bivariate associations and multiple logistic regression for multivariate analysis with a significance level of α = 0.05. Results: The findings revealed that all service-related variables—requirements, procedures, service completion time, costs/fees, service product specifications, staff competence, staff behavior, complaint handling, and facilities and infrastructure—were significantly associated with patient satisfaction (p < 0.05). The dominant factors influencing patient satisfaction were staff competence and staff behavior, both of which were strongly related to patients’ experiences in receiving care. Conclusion: Patient satisfaction is influenced by the synergy of all service aspects; therefore, quality improvement efforts must be comprehensive, integrative, and sustainable. This study recommends that hospitals strengthen the competence of health care providers, improve facilities and infrastructure, and simplify administrative processes to enhance patient satisfaction.
