Abstract

Pregnancy-related low back pain (LBP) is prevalent in late gestation and can negatively affect physical comfort and psychological well-being. Non-pharmacological interventions such as antenatal yoga are increasingly incorporated into routine care; however, pragmatic evidence from community-based settings remains limited. This study examined within-subject changes in LBP severity among third-trimester pregnant women participating in a structured antenatal-yoga program delivered at a community midwifery clinic. Researchers conducted a single-group pre-experimental pretest-posttest study at an independent midwifery clinic in Gunungsitoli, Indonesia. Forty pregnant women ≥28 weeks' gestation were recruited through purposive sampling. The intervention consisted of supervised prenatal-yoga sessions held three times per week over four weeks. Pain intensity was assessed before and after the program using the Numeric Rating Scale (NRS) and categorical severity bands (mild, moderate, severe). Pre-post differences were analysed using the Wilcoxon signed-rank test. Participation in antenatal yoga was associated with a clinically meaningful reduction in pain severity. Prior to the intervention, 62.5% of participants reported moderate pain and 37.5% reported mild pain; no cases of severe pain were observed. Following the intervention, 82.5% reported mild pain and 17.5% reported moderate pain. The change in NRS scores was statistically significant (p < 0.001). In this pragmatic third-trimester cohort, engagement in a structured antenatal yoga program was linked to reduced LBP severity and a shift toward milder pain categories. These findings support the feasibility of integrating antenatal yoga into routine prenatal care as a non-pharmacological option. Future controlled studies incorporating effect sizes, confidence intervals, functional outcomes, adherence andsafety monitoring, and short-term follow-up are recommended to strengthen casual inference and inform optimal program design.

Abstract

Postpartum visits by independent midwives play a critical role in initiating and sustaining exclusive breastfeeding. However, operational and institutional barriers may compromise their effectiveness, particularly in semi‑urban and rural settings such as Deli Tua District. This study examined the association between these barriers and exclusive breastfeeding practices among mothers in Deli Tua. A quantitative cross-sectional study was conducted in 2025, involving all independent midwives in the district (n = 85) and a purposive sample of 120 postpartum mothers (1-6 weeks post-delivery). Data were collected using structured questionnaires and analyzed through Chi-Square tests and multivariate logistic regression at a 95% confidence level. Key barriers negatively associated with exclusive breastfeeding included lack of government incentives (OR = 0.23; 95% CI: 0.09-0.61; p = 0.004), excessive workload and fatigue (OR = 0.33; 95% CI: 0.14-0.78; p = 0.013), high operational costs (OR = 0.38; 95% CI: 0.17-0.83; p = 0.015), and limited time for visits (OR = 0.43; 95% CI: 0.19-0.96; p = 0.043). Conversely, institutional support from health centers significantly increased the likelihood of breastfeeding success (OR = 2.01; 95% CI: 1.01-4.01; p = 0.046). Socio-cultural factors such as stigma and customary practices showed no significant association. To enhance the effectiveness of postpartum care and promote exclusive breastfeeding, the study recommends implementing performance-based incentives, reducing workload burdens, providing financial subsidies, and establishing standardized visit-time guidelines. Strengthening cross-sectoral collaboration and resource allocation is essential to improve service delivery and breastfeeding outcomes.

Abstract

Disturbances in sleep are common among pregnant women, especially in the third trimester, and can negatively impact the health of both the mother and fetus. Non-pharmacological approaches, such as prenatal yoga, offer a safe and effective way to improve sleep quality. This study aims to evaluate the effectiveness of prenatal yoga in enhancing sleep quality, blood pressure, and breathing among pregnant women in the third trimester in the Bah Kapul and Simarimbun Health Centre areas, Pematangsiantar City. A quasi-experimental design was employed, with an intervention group (n = 30) and a control group (n = 30). The intervention group participated in prenatal yoga sessions lasting 60 minutes, three times a week, for eight weeks (minimum 12 sessions). Sleep quality and disturbance were measured using a dedicated assessment tool, and data analysis was conducted with SPSS. Results showed that prior to the intervention, most participants in both groups reported poor sleep quality. After the intervention, significant improvements were observed in the intervention group (p < 0.001), including a reduction in severe sleep disturbances from 6.7% to 0%. The median sleep quality score increased by 1 point in the intervention group, compared to no change in the control group (p = 0.010), while the sleep disturbance score decreased by a median of 4 points in the intervention group (p = 0.019). No significant changes were found in blood pressure or breathing (p > 0.05). The study received ethical approval from the Health Research Ethics Committee of Politeknik Kesehatan Kemenkes Medan (Reference No: 01.26.696 /KEPK/POLTEKKES KEMENKES MEDAN 2024), and written informed consent was obtained from all participants. In conclusion, prenatal yoga significantly improved sleep quality and reduced sleep disturbances in pregnant women in the third trimester and is recommended as part of the antenatal care program at health centers.

Abstract

Despite the widespread Islamization in Indonesia, a corresponding increase in life satisfaction among its population has not been clearly observed. This study investigates the impact of religiosity on life satisfaction among students in the Faculty of Teacher Training at the Islamic State University of North Sumatra. Employing a quantitative, cross-sectional design, the research was conducted between October and November 2023. The study population comprised 7.801 students, from which a sample of 380 was selected. The primary variables examined were religiosity (independent variable) and life satisfaction (dependent variable). Data were analyzed using both univariate and multivariate methods: descriptive statistics for univariate analysis and linear regression for multivariate analysis. All statistical procedures were performed using JASP software, version 17. Findings indicate that religiosity significantly influences life satisfaction among students in the Islamic education faculty (p < 0.001). Students with high levels of religiosity were found to be 6.730 times more likely to report greater life satisfaction. These results suggest that religiosity is a strong predictor of life satisfaction and that the regression model provides a robust explanation of the observed data. Nonetheless, the model may not capture all contributing factors, and future research should explore additional variables that may affect life satisfaction.

Abstract

Physical violence remains a global public health concern, with limited Indonesia-specific data on non-fatal injuries. This study aims to describe the characteristics of victims of physical abuse based on age, sex, and wound patterns using forensic medical reports to support public health strategies and forensic practices. A retrospective descriptive study was conducted using 150 Visum et Repertum (VeR) reports from living victims of physical violence treated at Bhayangkara Sartika Asih Hospital, Bandung, in 2022. Reports were selected through purposive sampling, including only those with complete documentation; cases involving deceased victims or unrelated to physical violence were excluded. Results showed that the most affected age group was 17-25 years (36.67%). Males represented the majority of victims (95.3%). The most common type of injury was bruises (34.52%), followed by abrasions (33.33%) and lacerations (21.03%). Among males, 83 (58%) sustained bruises, while among females, 5 (71%) had abrasions. Head injuries were predominant, with 30 cases (20%) having single wounds and 89 cases (59.3%) multiple wounds. These findings highlight the importance of targeted interventions for young males and suggest that injury surveillance systems should better capture non-fatal violence trends. The observed patterns may reflect social dynamics and risk behaviors prevalent in this demographic group, warranting further investigation Keyword: Physical Violence, Trauma, Wound Pattern, Forensic Medicine

Abstract

Deli Serdang Regency in North Sumatra remains a priority area for malnutrition interventions due to persistent socioeconomic disparities, under-resourced rural health systems, and chronic food insecurity. Although national data (Riskesdas 2018) report a stunting prevalence of 21.3%, localized health surveillance in villages such as Tanjung Anom indicates rates exceeding 30%, highlighting elevated nutritional risk among toddlers. A matched case-control study was conducted involving 64 toddlers aged 12-59 months (32 malnourished, 32 well-nourished), matched 1:1 by age group and gender. Malnutrition was defined according to WHO anthropometric Z-scores (< -2 SD for weight-for-age or height-for-age). Data collection included direct anthropometric measurement and structured maternal interviews, incorporating a 24-hour dietary recall. Conditional logistic regression was employed to account for matching, and standardized protocols were implemented to minimize selection and information bias. After adjusting for confounders, four key risk factors were significantly associated with malnutrition: poor maternal nutritional knowledge (adjusted OR = 3.91; 95% CI: 1.18-12.95; p = 0.026), low household income (aOR = 10.23; 95% CI: 2.00-52.39; p = 0.005), recent infectious disease (aOR = 6.11; 95% CI: 1.79-20.84; p = 0.004), and insufficient food intake (aOR = 72.30; 95% CI: 12.98-402.61; p < 0.001). The wide confidence interval for dietary intake reflects limitations in sample size and variability in exposure. This study is among the first matched case-control investigations in rural North Sumatra to quantitatively link maternal nutrition knowledge with child nutritional status using localized data and WHO standards. The findings underscore the need for targeted, nutrition-sensitive interventions, including strengthening Community Health Post (Posyandu) services, enhancing maternal nutrition education, promoting community home gardens, and improving rural health infrastructure. This model offers potential for scale-up through multisectoral collaboration and context-specific policy adaptation Keywords: Malnutrition, toddlers, maternal knowledge, food intake, infectious disease, Deli Serdang, nutrition-sensitive policy

Abstract

This study evaluates the effectiveness of internal verifiers at Muhammadiyah Hospital North Sumatra in minimizing delayed inpatient claims submitted to BPJS Kesehatan, Indonesia's national health insurance agency. A mixed-methods sequential explanatory design was employed, combining quantitative data from 2020 (prior to verifier recruitment) and 2022 (post-recruitment) with qualitative insights from interviews with internal verifiers, coders, and other stakeholders, as well as a review of claim files processed by the hospital's BPJS Unit. Interview protocols were adapted from a 2018 study at Koja Hospital, North Jakarta, and data were analyzed using the Miles and Huberman approach, with findings integrated across methods. Source triangulation ensured validity and reliability. Results showed that internal verifiers significantly reduced the proportion of delayed claims despite an overall increase in submissions, with the highest rate of pending claims dropping from 25.6% in 2020 to 17.9% in 2022. Of the 2022 delays, 31.2% were due to BPJS Kesehatan system errors or confirmation processes, indicating that only two-thirds stemmed from hospital-related issues. Qualitative analysis identified key contributors to delays, including diagnostic coding errors, inconsistent understanding among BPJS verifiers, incomplete documentation, limited staff knowledge, and human resource inaccuracies. The presence of internal verifiers improved claim management and hospital revenue by increasing eligibility and accelerating approvals. To further optimize claim processing, strategies such as enhancing coding accuracy, improving staff competency, ensuring documentation completeness, and adopting electronic systems with supportive incentives are recommended.

Abstract

Hypertension is a degenerative condition that significantly contributes to global morbidity and mortality, making medication adherence a critical factor in achieving long-term therapeutic success. This study investigates the relationship between patient-related factors and adherence to antihypertensive medication. A cross-sectional analytical survey was conducted among 195 hypertensive patients in Samarinda, East Kalimantan. Data were collected using a structured questionnaire incorporating the MMAS-8 scale, which categorizes adherence into high (score = 8), moderate (score = 6-7), and low (score < 6), alongside a validated instrument assessing sociodemographic, clinical, and behavioral determinants. Statistical analysis employed chi-square tests and odds ratios (OR) with 95% confidence intervals. The majority of patients demonstrated low adherence (65.6%), followed by moderate (28.7%) and high adherence (5.6%). Significant associations were found between adherence levels and gender (P = 0.033, OR = 0.513, 95% CI: 0.276-0.951), knowledge level (P = 0.013, OR = 2.190, 95% CI: 1.176-4.079), duration of hypertension (P = 0.017, OR = 0.483, 95% CI: 0.265-0.881), and insurance status (P = 0.004, OR = 0.080, 95% CI: 0.009-0.680). Knowledge level emerged as the most influential factor in promoting adherence. These findings highlight the importance of targeted educational interventions and sustained support for patients at risk of poor adherence, aiming to optimize antihypertensive therapy and prevent long-term complications. The study advocates for strengthened evidence-based clinical practices and underscores the need for health policy reforms particularly in patient education and insurance accessibility to improve hypertension management in primary care settings.

Abstract

Case management is a collaborative process involving the planning, coordination, monitoring, and evaluation of services provided to patients to meet their optimal health needs. This study aims to examine the factors associated with the implementation of case management care. This analytical cross-sectional study was conducted at Badung Regency Hospital, Bali. A total of 248 healthcare professionals-including doctors, nurses, and midwives who met the inclusion criteria participated in the study. Data were collected using a structured questionnaire and analysed through univariate, bivariate (Chi-square), and multivariate (binary logistic regression) methods. Chi-square analysis revealed that case manager knowledge, hospital management support, institutional policies, and multidisciplinary team collaboration were significantly associated with the implementation of case management (p < 0.05). The most influential factors were case manager knowledge (AOR = 21.16; 95% CI: 1.66-56.07) and multidisciplinary team collaboration (AOR = 13.2; 95% CI: 1.72-100.93). The findings suggest that enhancing case managers' knowledge and fostering stronger interprofessional collaboration may significantly improve the implementation of case management care in hospital settings Keywords: Case management, Case manager knowledge, Collaboration, Hospital care

Abstract

Older adults face a heightened risk of falling both indoors and outdoors due to age-related declines in balance. One contributing factor is weakness or instability in the ankle joint, which can significantly impair postural control and lead to limitations in daily activities. As balance deteriorates, functional capacity in the lower limbs declines, further hindering mobility and independence. Enhancing ankle strength and stability is therefore essential to improving balance and reducing fall risk in this population. This study investigates the impact of Strategic Ankle Exercise on balance and falling risk among older adults. Employing a one-group pre-test and post-test experimental design, the study involved 33 participants who met the inclusion criteria and were selected through total sampling. Balance was assessed using the Berg Balance Scale (BBS) and the Timed Up and Go (TUG) test. Paired sample t-tests conducted via SPSS revealed a significant improvement in dynamic balance following the intervention: BBS scores increased from 44 to 50.8, while TUG scores decreased from 15.5 to 10.1 (p < 0.001). A correlation analysis indicated a strong negative relationship between changes in BBS and TUG scores (r = -0.86; p < 0.001), suggesting that improvements in balance were associated with reduced fall risk Strategic Ankle Exercise emerges as an effective, evidence-based intervention for enhancing balance and minimizing fall risk in older adults. These findings support the integration of this program into geriatric care strategies. Future research should explore optimal exercise dosage and customization to maximize benefits across diverse age groups and functional levels. Keyword: Balance, Ankle strategic exercise, BBS, TUG
