Abstract

Lack of sexual knowledge and increasing negative sexual attitudes in Indonesia could lead to risky sexual behavior. This problem increases teenage pregnancy, sexually transmitted infections, and abortion among adolescents. This study aimed to determine the relationship between sexual knowledge and sexual attitudes towards sexual behavior among junior high school students in West Jakarta. This study was cross-sectional, conducted on 544 junior high school students in West Jakarta. Measuring instruments used were characteristic questionnaires, sexual knowledge questionnaires, sexual attitude questionnaires, and sexual behavior questionnaires. Data analysis was performed using bivariate (chi-square). This study shows 79.2% of the respondents had low sexual knowledge, 45.6% respondents had negative sexual behavior, and 48.2% respondents had risky sexual behavior. This study finds that most male respondents had low sexual knowledge (80.8%), low sexual attitude (56.8%), and “less-safe” risky sexual behavior (60.0%), while “not-safe” risky sexual behavior (2.7%) was found higher in female respondents. Bivariate analysis shows a significant relationship between sexual knowledge (p=0.006; 95% OR=1.763 |95% CI=1.151-2.698) and sexual attitude (p=<0.001; OR=2.852 | 95% CI=2.012-4.043) towards sexual behavior. In conclusion, low sexual knowledge and negative sexual attitudes increase the risk of risky sexual behavior.

Abstract

Background: The diagnosis and management of chronic diseases, such as Acute Lymphoblastic Leukemia (ALL), are significant for the quality of life of parents. In addition, several factors contribute to the quality of life of parents whose children battle ALL, including characteristics, duration of childcare, mental health, and family functioning. Therefore, this study aims to identify factors influencing the quality of life of parents whose children have ALL at the Childhood Cancer International Foundation in Jakarta. Methods: This cross-sectional study recruited 109 parents at the Childhood Cancer International Foundation as respondents. The assessment tools used included a Characteristics questionnaire, Self-Rating Questionnaire-20, APGAR Questionnaire, and WHOQOL-BREF questionnaire. Additionally, collected data were subjected to univariate, bivariate, and multivariate analysis. Results: Among the 109 respondents with an average age of 38 years and mean childcare duration of 28 months, 66.1% were females, 100% believed in God, 73.4% had partners, 47.7% possessed higher education, 83.5% earned below the regional minimum wage, 66.1% experienced mental health problems, and 11.9% had family dysfunction. Bivariate analysis showed a significant relationship between gender, mental health, and quality of life (p0.05). Multivariate analysis showed that marital status, education, economic status, and family functioning significantly correlated with quality of life. Conclusions: In conclusion, gender, marital status, education, economic status, mental health, and family functioning were found to exert a significant influence on the quality of life of parents raising children with ALL.

Abstract

This study aimed to develop biodegradable Mg-6Zn hydroxyapatite (Mg-6Zn HAp) biocomposites for potential use in bone replacement applications. The hydroxyapatite (HAp) powders, sourced from cow bone, were synthesized through an eco-friendly and cost-effective process, leveraging bioresources for material sustainability. The Mg-6Zn and HAp powders were mechanically mixed through ball milling for six hours to ensure homogeneity. The resultant powder mixture was then subjected to isostatic pressing at a high pressure of 570 MPa, forming a dense coin-shaped composite with a 1.5 cm diameter. This coin was consolidated in a capsule furnace at elevated temperatures for one hour to enhance material integrity. The Mg-6Zn HAp alloy was thoroughly characterized using X-ray diffraction (XRD) to assess phase formation and crystallographic structure, and Scanning Electron Microscopy coupled with Energy Dispersive X-ray Spectroscopy (SEM-EDX) to examine microstructural features and elemental composition. For composite preparation, varying amounts of HAp (5%, 8%, and 12%) were incorporated into the Mg-6Zn matrix. SEM analyses revealed a uniform distribution of HAp particles along the boundaries of matrix particles, enhancing composite structure and stability. Results demonstrated that with an increase in HAp content, there was a corresponding improvement in the relative density and hardness of the composites. The corrosion rate decreased with higher HAp content, indicating improved biocompatibility and stability in physiological environments. This suggests that the Mg-6Zn HAp biocomposites, with their tailored microstructure and enhanced mechanical properties, hold promise for use in biodegradable bone replacement applications.

Abstract

Background: Overweight and obesity are rising among Indonesian adolescents and are known risk factors for hypertension. This study aimed to examine the relationship between overnutrition status and blood pressure among adolescents.Method: A cross-sectional study was conducted from May to September 2024, among overweight and obese adolescents aged 12–16 years in Central Jakarta, Indonesia.  Nutritional status was determined by body mass index (BMI) Z-scores based on CDC growth charts, adjusted for sex and age. Blood pressure was measured using a digital sphygmomanometer and classified according to the 2017 AAP guidelines. Data were analyzed using chi-square tests. Results: A total of 98 adolescents participated (67.3% male; mean age 13 years). Overweight (49%) and obesity (51%) were almost equally distributed, with the highest BMI recorded at 46.7 kg/m². More than half (58.2%) had elevated blood pressure, with one case reaching grade 2 hypertension (143/84 mmHg). Overnutrition status was significantly associated with elevated blood pressure (p=0.044). Stratified analysis showed a strong association among males (p=0.005), where 42.4% of obese males exhibited elevated blood pressure, but no significant association was observed among females (p=0.58).Conclusion: Overnutrition is significantly associated with elevated blood pressure among adolescents, particularly in males. Early interventions promoting balanced nutrition, physical activity, and healthy lifestyle habits are critical to reducing the long-term cardiovascular risk in this age group.

Abstract

Diabetes Mellitus adalah gangguan metabolik yang ditandai dengan hiperglikemia kronis akibat gangguan regulasi glukosa. Di Indonesia, prevalensi diabetes pada orang dewasa mencapai 10,8%. Penyakit tiroid, yang disebabkan oleh kelainan fungsi kelenjar tiroid, juga menjadi masalah kesehatan yang mempengaruhi metabolisme tubuh. Pemeriksaan HbA1c dan TSH memiliki peran penting dalam deteksi dini dan pengelolaan kondisi ini. HbA1c mencerminkan kontrol glukosa darah selama 2-3 bulan terakhir, sedangkan TSH digunakan untuk mendeteksi gangguan fungsi tiroid. Program bakti sosial yang diadakan di Gereja Katolik Santo Petrus & Paulus, Jakarta Barat, diikuti oleh 43 peserta. Hasilnya menunjukkan 6 orang (13,95%) memiliki kadar HbA1c ≥6,5%, di mana 4 orang baru terdiagnosa diabetes. Selain itu, 8 orang (18,60%) memiliki kadar TSH <0,45 mU/L, yang mengindikasikan kemungkinan hipertiroidisme. Program ini dapat meningkatkan kesadaran masyarakat akan pentingnya deteksi dini dan pengelolaan penyakit. Kegiatan serupa sebaiknya dilakukan secara rutin dengan tambahan edukasi kesehatan mengenai pencegahan penyakit tidak menular dan pola hidup sehat untuk dampak yang lebih luas
