Abstract

Background : Adolescent nutrition plays an important role in determining long-term health outcomes. However, poor nutritional knowledge and unhealthy snack consumption are often linked to imbalanced body weight among adolescents. This study aimed to analyze the association between nutrition knowledge and snack consumption behavior with nutritional status among PMR (Youth Red Cross) students at SMKN 15 Samarinda. Objective : Analyzing the relationship between nutritional knowledge and snack consumption among Red Cross Youth members at SMKN 15 Samarinda. Research Methods/ Implementation Methods : A cross-sectional quantitative study was conducted among 41 PMR students at SMKN 15 Samarinda. Data were collected using a validated and reliable questionnaire, which consisted of 15 nutrition knowledge items (Cronbach’s Alpha=0.902). Anthropometric data were obtained to determine Body Mass Index-for-Age (BMI/A) based on the Indonesian Ministry of Health Regulation. Statistical analysis included descriptive statistics and the Chi-square test, with a significance level set at p<0.05. Results : The majority of respondents were female (56.1%) and had a normal nutritional status (82.9%), with a mean BMI of 20.5 kg/m2. The bivariate analysis showed a significant association between nutrition knowledge and nutritional status (p=0.042), indicating that students with higher nutrition knowledge tended to have normal BMI-for-age compared to those with lower knowledge levels. In contrast, no significant association was found between snack consumption behavior and nutritional status. Conclusion/Lesson Learned : Nutrition knowledge significantly influences adolescent nutritional status. Strengthening school-based nutrition education and promoting healthy snack selection are essential strategies to improve adolescent health and prevent malnutrition.

Abstract

Background : Intermittent fasting (IF), often integrated into carbohydrate-restricted diets, has rapidly gained interest among the general public and patients with cardiometabolic disease. However, there are limited studies investigating the relationship between IF knowledge, IF practice and healthy lifestyle behaviors. Objective : The study aimed to determine the association between the level of IF knowledge, Intermittent Fasting practices and healthy lifestyle behaviors among adults in Samarinda, Indonesia. Research Methods/ Implementation Methods : This study employed a cross-sectional design, involving 129 respondents recruited through an online questionnaire. Data collected included demographic characteristics, IF knowledge, Intermittent Fasting practices, and healthy lifestyle behaviors (covering diet, physical activity, sleep duration, non-alcoholic consumption, non-smoking, and stress management). Data analysis utilized the Chi-Square test to assess the association between respondent characteristics and IF practices, and the Spearman correlation test to analyze the association between IF knowledge and healthy lifestyle behaviors. Results : There was no significant difference found between most respondent characteristics and IF practices, except for having received IF information (p<0.0001). A significant association was observed between IF knowledge and IF practices ((p<0.0001). However, there was no association between IF knowledge and overall healthy lifestyle behaviors, including dietary patterns (p=0.249). Conclusion/Lesson Learned : Higher IF knowledge is significantly associated with IF practices, but not associated with overall healthy lifestyle behaviors. These findings emphasize the importance of strengthening evidence-based health education to improve public understanding of healthy lifestyle components as an effort toward developing quality human resources. An integrated health promotion strategy that combines knowledge dissemination with practical behavioral support is recommended to enhance community well-being.

Abstract

Background : Schoolchildren’s snacks have the potential to contain hazardous food additives such as formalin, borax, rhodamine B, and methanil yellow, which are prohibited in food products. Prolonged exposure to these substances can pose serious health risks to children. Objective : This study aimed to assess the presence of hazardous chemical substances in school snacks sold at SDN 009 Karang Asam, Samarinda City, and to evaluate hygiene and food handling practices by school food vendors Research Methods/ Implementation Methods : A descriptive survey design was employed using direct observation and rapid testing methods. Three popular snack items—iced tea, jelly, and colored mini pancakes (terang bulan)—were tested using rapid test kits for the presence of formalin, borax, rhodamine B, and methanil yellow. Results : All samples tested negative for the four hazardous substances. However, several hygiene- related deficiencies were observed, including the unclear source of water and ice used in preparation and the lack of personal protective equipment (PPE) such as gloves and masks among vendors. Conclusion/Lesson Learned : While the tested school snacks did not contain prohibited food additives, the hygiene and sanitation practices of the vendors were suboptimal. Regular education and supervision are essential to ensure comprehensive food safety for schoolchildren

Abstract

Background : Timeliness of laboratory result reporting is a key quality indicator that reflects efficiency, professionalism, and customer satisfaction in accordance with ISO 15189:2022 standards. Reporting delays remain a common issue in public laboratories due to limited resources and system inefficiencies. This study addresses practical, scientific, and theoretical gaps in understanding factors influencing turnaround time (TAT) in regional laboratories and how digital quality systems can improve service performance. Objective : This study aimed to analyze the level of reporting timeliness and identify factors contributing to delays at the Provincial Health Laboratory (UPTD Labkes) of East Kalimantan during January–June 2025. Research Methods/ Implementation Methods : A descriptive quantitative approach was applied using primary data from laboratory test logs, interviews, and field observations, along with secondary data from internal quality indicator reports. Results : he findings revealed an average reporting timeliness of 88.2%, still below the minimum internal quality target of 90%, with variations among divisions. The Biomolecular and Calibration units achieved 100%, while the Congenital Hypothyroid Screening (CHS) program recorded the lowest timeliness at 86.8%. Reporting delays were mainly due to high workloads, limited human resources, suboptimal LIS/SIL transition, technical constraints in MMPI scoring, and reagent supply delays. Conclusion/Lesson Learned : Improvement strategies include optimizing human resource planning, strengthening integrated digital systems, enhancing staff competence through the PDCA cycle, and real-time reagent monitoring. Digital transformation and continuous quality system implementation are strategic measures to achieve fast, accurate, and trustworthy laboratory services aligned with international standards.

Abstract

Background : Adolescent obesity in Indonesia is increasing and poses a high risk of chronic diseases such as type 2 diabetes and cardiovascular disorders. One contributing factor is poor nutrition knowledge and unhealthy eating patterns. Objective : This study aimed to evaluate the effectiveness of nutrition education in improving adolescents’ knowledge as an effort to prevent obesity. Research Methods/ Implementation Methods : The intervention was delivered through interactive lectures, group discussions, and visual media (posters, booklets, videos), covering topics such as balanced nutrition, reducing excessive sugar and fat intake, and choosing healthy snacks. Thirty adolescent respondents participated in a pretest and posttest, with data analyzed using the Wilcoxon test and crosstab. Results : The Wilcoxon test showed a significant difference between pretest and posttest scores (p = 0.004), with all respondents achieving a good knowledge category after the intervention. However, 73.3% of respondents still demonstrated less supportive attitudes. Conclusion/Lesson Learned : In conclusion, nutrition education effectively increased nutrition knowledge, but sustainable programs focusing on behavior habituation through the involvement of schools, families, and social media are recommended to foster long-term positive attitudes.

Abstract

Background : Exclusive breastfeeding during the first six months of life is essential for optimal infant growth, development, and disease prevention. However, the coverage of exclusive breastfeeding remains below national and regional targets in many areas of Indonesia Objective : This study aimed to analyze the determinants of exclusive breastfeeding among mothers with infants aged 6–24 months in the working area of Puskesmas Waru, Penajam Paser Utara Regency, East Kalimantan Province. Methods : An observational analytic study with a cross-sectional design was conducted among 122 mothers selected using simple random sampling from a population of 345 mothers. Data were collected using structured questionnaires measuring maternal knowledge, maternal attitude, early initiation of breastfeeding (IMD), maternal occupation, family support, health worker support, and exclusive breastfeeding practices. Data were analyzed using Chi-square tests with a significance level of α = 0.05. Results : The results showed that 44.3% of mothers practiced exclusive breastfeeding, while 55.7% did not. Maternal knowledge (p = 0.000), maternal attitude (p = 0.000), and family support (p = 0.000) were significantly associated with exclusive breastfeeding. In contrast, maternal occupation (p = 0.875) and health worker support (p = 0.083) were not significantly associated with exclusive breastfeeding Conclusions : These findings indicate that behavioral and social factors play important roles in influencing exclusive breastfeeding practices. Strengthening health promotion programs that improve maternal knowledge, foster positive breastfeeding attitudes, and enhance family involvement is essential to increase exclusive breastfeeding coverage.
