Abstract

Background: Academic stress and low physical activity are recognized as factors that may disrupt the hypothalamic–pituitary–ovarian axis, leading to menstrual cycle irregularities among young women. First-year midwifery students are particularly vulnerable because of academic demands and sedentary lifestyles. This study aimed to analyze the relationship between academic stress and physical activity and menstrual cycle regularity among first-year midwifery students at the Health Polytechnic of the Ministry of Health, Denpasar. Methods: This analytical cross-sectional study involved 83 first-year midwifery students selected using total sampling. Academic stress was measured using the Student-life Stress Inventory (SSI), while physical activity was assessed using the International Physical Activity Questionnaire–Short Form (IPAQ-SF). Menstrual cycle regularity was determined through a structured questionnaire. Data were analyzed using the Fisher–Freeman–Halton exact test and multivariate logistic regression. Results: Most respondents experienced moderate to severe academic stress (87.9%), low physical activity (92.8%), and irregular menstrual cycles (78.3%). Academic stress was significantly associated with menstrual cycle regularity (p = 0.003). Physical activity was also significantly associated with menstrual cycle regularity (p = 0.026). Multivariate analysis showed that physical activity was the most dominant factor influencing menstrual cycle regularity (OR = 27.692). Conclusions: Academic stress and physical activity were significantly associated with menstrual cycle regularity among first-year midwifery students. Maintaining adequate physical activity and implementing effective stress management strategies are recommended to improve reproductive health among university students.

Abstract

Introduction: The Maternal Mortality Ratio (MMR) is a key indicator of public health and maternal healthcare quality. In Indonesia, the MMR declined to 144 per 100,000 live births in 2025, achieving the national strategic target of 183 per 100,000 live births. However, further reductions are needed to meet the 2030 Sustainable Development Goals (SDGs) target of 70 per 100,000 live births. The updated 2024 Maternal and Child Health Handbook supports pregnancy monitoring and birth preparedness. This study aimed to examine birth preparedness among pregnant women through the use of the Maternal and Child Health Handbook. Methods: This study employed a qualitative research method with a phenomenological approach. The study was conducted in the Candimulyo Village area, Madiun Regency, in March 2026. The study informants consisted of 12 pregnant women in their second and third trimesters who were attending prenatal check-ups. Data collection was conducted through in-depth interviews, followed by analysis involving data categorization, data presentation, and drawing conclusions. Results: The study results indicate that the majority of pregnant women make effective use of the Maternal and Child Health Handbook when reviewing birth preparations. Conclusions: The conclusion of this study is that the better a mother utilizes the Maternal and Child Health Handbook, the more effective her efforts to prepare for childbirth will be. It is recommended to seek support from healthcare professionals (midwives) and family members when preparing for childbirth by utilizing the Maternal and Child Health Handbook.

Abstract

Background: Exclusive breastfeeding is the practice of providing only breast milk without any additional food or drink for the first six months of an infant’s life. The coverage of exclusive breastfeeding in Indonesia has not yet reached the target, partly due to the low level of knowledge and compliance among breastfeeding mothers. One effort to improve this condition is through health education using leaflet media. This study aimed to determine the effect of leaflet media on the knowledge and compliance of breastfeeding mothers in providing exclusive breastfeeding at Ulumahuam Public Health Center, South Labuhan Batu Regency, in 2025. Methods: This research used a quasi-experimental design with a one-group pretest-posttest approach. The population consisted of 72 breastfeeding mothers, with a sample of 42 respondents selected using a simple random sampling technique. Data were collected using questionnaires and analyzed using the paired t-test and chi-square test. Results: The results showed a significant increase in mothers' knowledge after they were given education through leaflet media, with a p-value = 0.000 (<0.05). In addition, there was a significant effect of leaflet media on mothers' compliance in providing exclusive breastfeeding, with a p-value = 0.002 (<0.05). This indicates that leaflet media is effective in improving knowledge and compliance among breastfeeding mothers. Conclusion: Leaflet media has a significant effect on increasing the knowledge and compliance of mothers in providing exclusive breastfeeding. It is recommended that health workers utilize leaflet media as an educational tool in promoting exclusive breastfeeding programs.

Abstract

Background: Promoting facility-based delivery remains challenging in geographically isolated areas, where limited access to healthcare increases maternal and neonatal risks. Video-based education may strengthen pregnant women's commitment to choosing a health facility for delivery; however, evidence of its effectiveness in remote settings is limited. This study aimed to examine the effect of video-based education on pregnant women's commitment to choosing facility-based delivery in the Rakumpit Public Health Center working area. Methods: A quantitative pre-experimental one-group pretest–posttest study was conducted among 35 pregnant women selected through total sampling. Participants received video-based education on the importance of facility-based delivery, risks of non-facility births, benefits of skilled birth attendance, childbirth services, and birth preparedness. Commitment was measured before and after the intervention using a structured questionnaire and analyzed with a paired samples t-test. Results: The mean commitment score increased significantly from 65.10 to 99.28 after the intervention, with a mean difference of 34.18 points. The proportion of women committed to facility-based delivery increased from 62.1% to 100%. A significant difference was observed between pre- and post-intervention scores (p < 0.001), indicating that video-based education effectively strengthened commitment to facility-based delivery. Conclusion: Video-based education effectively improves pregnant women's commitment to choosing facility-based delivery and may be integrated into routine antenatal care to increase the utilization of skilled delivery services in geographically disadvantaged areas.

Abstract

Background: Geplakkin is a digital application that enables the general public to report, monitor, and obtain information on Aedes mosquito density as part of a monitoring system. The objective of this study was to analyze the relationship between the level of use of the Aedes mosquito app (UAR) and the intention to eliminate mosquito breeding sites, as well as the relationship between the level of use and attitudes toward eliminating mosquito breeding sites among Geplakkin app users in Pontianak. Methods: The study population consisted of households in Pontianak. A total of 240 Geplakkin app users were selected through targeted sampling. The inclusion criterion was owning a smartphone capable of installing and using the app. Data were analyzed using univariate and bivariate analyses. Bivariate analysis was performed using Pearson’s product-moment correlation and Spearman’s rank correlation. Results: The results showed a weak but statistically significant positive relationship between the level of Geplakkin app usage and the intention to eliminate mosquito breeding sites (r = 0.310, p = 0.000). The variable attitude toward mosquito breeding site elimination showed a very weak but statistically significant positive correlation with UAR (r = 0.149, p = 0.021). Both variables exhibited a positive association, indicating that higher UAR values are associated with stronger intentions and more positive attitudes toward eliminating mosquito breeding sites. Conclusion: Continued use of the Geplakkin monitoring app is recommended, as users’ positive responses to the app have the potential to strengthen their intention to eliminate mosquito breeding sites and thereby foster a positive community attitude toward mosquito breeding site elimination (PSN) efforts as part of dengue vector control.

Abstract

Background: Industrial tanning wastewater contains high concentrations of total chromium (Cr) due to the use of chromium sulphate in the tanning process. This study aims to evaluate the effect of filtration using avocado seed charcoal, bamboo charcoal, and a combination of both in a multi-stage filtration device model on the reduction of total chromium in leather tanning wastewater. Methods: The study used a quasi-experimental method with a pretest–posttest group design, involving 60 samples (30 pretest, 30 posttest). The wastewater flowed through three filtration units (Tank I = avocado seed charcoal; Tank II = bamboo charcoal; Tank III = combination of avocado seed charcoal + bamboo) with a flow rate of 800 ml/minute, a media height of 9 cm, and a contact time of 1 hour. Data analysis included Kolmogorov–Smirnov normality test and One-Way ANOVA test (α=0.05) followed by LSD test. Results: The results showed that the highest Cr reduction occurred in Tank III with an average reduction of 22.72 ppm, compared to Tank I (19.14 ppm) and Tank II (14.46 ppm). The ANOVA test showed a significant difference between treatments (p = 0.034). The LSD test confirmed a significant difference between Tank II and Tank III (p = 0.010), with the best effectiveness in combination filtration (Tank III). The filtration model combining avocado seed charcoal and bamboo charcoal has the potential to be an efficient and environmentally friendly adsorption technology for reducing chromium in leather tanning wastewater.

Abstract

Background: Hepatitis B remains a global health problem that can progress to cirrhosis and liver cancer. Nurses face elevated occupational exposure through contact with patients’ blood and body fluids, making vaccination compliance essential, yet completion rates among health workers remain suboptimal. This study aimed to determine the relationship between Health Belief Model (HBM) components and Hepatitis B vaccination compliance among nurses at RSUD H.M. Ryacudu Kotabumi, North Lampung, in 2026. Methods: This analytic quantitative study used a cross-sectional design. A sample of 105 nurses was selected through proportionate stratified random sampling from a population of 173 nurses. Data were collected using a structured questionnaire adapted from validated HBM instruments and analyzed univariately, bivariately using the Chi-square/Fisher Exact test, and multivariately using multiple logistic regression. Results: Among the 105 respondents, 71 (67.6%) were compliant with Hepatitis B vaccination. Bivariate analysis showed significant associations between compliance and perceived susceptibility (p=0.003), perceived severity (p<0.001), perceived benefits (p<0.001), perceived barriers (p<0.001), cues to action (p<0.001), and self-efficacy (p<0.001). Multivariate analysis identified perceived benefits as the most dominant factor (p=0.003; OR=13.63; 95% CI 2.39–77.71), followed by self-efficacy (p=0.007; OR=12.44) and perceived barriers (p=0.004; OR=0.09). Conclusion: HBM components are associated with Hepatitis B vaccination compliance among nurses, with perceived benefits as the most dominant determinant. Hospitals should prioritize strengthening nurses’ understanding of vaccination benefits through targeted health education, workplace policy support, and continuous promotion to improve occupational vaccination coverage.

Abstract

Background: Sexual harassment among adolescents remains a critical global issue, particularly within educational settings. While sexual literacy is often promoted as a primary defense, the translation of knowledge into protective behavior remains under-researched. This study aims to analyze the correlation between sexual literacy, the incidence of sexual abuse, and prevention efforts among health science students through the lens of Social Learning Theory. Methods: A cross-sectional survey was conducted in November 2024 at the dr. Soepraoen Army Hospital Institute of Technology, Health, and Science, Malang, Indonesia. A total of 88 nursing and midwifery students were recruited using consecutive sampling. Data were collected via a validated online questionnaire covering sexual literacy, abuse experiences, and preventive actions. Statistical analyses included the Fisher Exact test for categorical associations and Spearman’s rank correlation for behavioral trends. Results: The majority of respondents (92%) demonstrated high sexual literacy; however, 20.5% reported experiencing sexual abuse. Bivariate analysis revealed no significant relationship between sexual literacy levels and the incidence of sexual abuse (p = 0.337). Conversely, a statistically significant, albeit modest, positive correlation was found between sexual literacy and prevention efforts (r = 0.240; p = 0.024). Despite high literacy, 58% of respondents did not implement active preventive measures, indicating a gap between knowledge and practice. Conclusion: High sexual literacy significantly influences the propensity to adopt preventive measures but does not directly reduce the risk of victimization. These findings suggest that individual knowledge is insufficient without systemic support. Comprehensive strategies must integrate psychosocial empowerment, self-efficacy, and institutional policies to bridge the gap between sexual awareness and effective protective behavior.

Abstract

Background: Insecticide-treated nets (ITNs) are an important malaria prevention measure, but household ownership does not always translate into consistent use. Understanding community compliance and barriers to ITN utilization is essential for effective malaria control. This study assessed ITN utilization usage patterns and community compliance in the Upper River Region (URR) of The Gambia to better understand the gap between possessing a net and using it correctly. Methods: A community-based study was conducted across seven districts in the URR: Sandu, Jimara, Wulli East, Wulli West, Basse (Fulladu East), Tumana, and Kantora. Data were collected from 1,000 households through interviewer-administered questionnaires and direct environmental observations. The Community Compliance Index (CCI) framework was used to assess nightly ITN use, knowledge of ITN benefits, barriers to use, and the physical condition and hanging of nets. Results:  ITN ownership was high, with 94.2% of respondents reporting sufficient nets for household members, while 78.5% reported sleeping under a net every night. Knowledge of ITN benefits was high, but consistent use was affected by nighttime heat, overcrowded sleeping areas, and inadequate net maintenance. Direct observations showed that 68.3% of nets were properly hanging over sleeping areas, indicating a gap between reported use and observed readiness for use. Conclusion: Despite high ITN ownership and awareness, environmental discomfort and household structural constraints remain important barriers to consistent utilization in the URR. Malaria control programs should complement ITN distribution with behavior-change interventions addressing proper net hanging, maintenance, and heat-related discomfort.
