Abstract

Disorders of the musculoskeletal system constitute a considerable health problem in industrialized societies. Low back pain (LBP) remains a common and costly problem among the workers. Workplace injuries, primarily musculoskeletal disorders, are a persistent problem for nursing. A cross-sectional study was conducted to investigate prevalence of LBP as well as the potential risk factors associated with LBP. These potential risk factors include individual characteristics, job duration, type of work, and manual handling knowledge and practice. Seventy-six subjects consisting of 30 nurses and 46 administrative workers were recruited into the study. Symptoms of LBP cases were assessed by means of a simple questionnaire, and the diagnosis of LBP was confirmed by clinical examination. The study showed that the overall point prevalence rate of LBP was 42.1%, while the overall 12-month prevalence rate was 69.7%. Occupational group and manual handling practice were independent predictors for point prevalence of LBP. Nursing occupation significantly increased the risk of point prevalence rate of LBP by 2.703 (95% C.I. OR 1.046 – 6.984) compared to administrative workers. Nurses with frequent manual handling practice had a 2.917-fold higher risk of developing a point prevalence of LBP, although this risk was statistically not significant (OR=2.917;95% C.I. 0.094-3.003). The study indicates that an association exists between manual handling practice and LBP prevalence.

Abstract

Pain of the musculoskeletal system, especially low back pain, is one of the most frequent problems with a high risk of disability. The aim of this research study was to determine the existence of an association between low back pain on one hand,  posture and step length on the other. This cross-sectional study was conducted on 77 healthy young adult subjects. Step length was measured with the Biodex Gait Trainer 2 (230 VAC). The study results indicate that 62.3% of the young adult subjects had suffered from low back pain. There was no significant association between gender and pain. In male subjects no significant association was found between pain on one hand and mean difference in step length and posture on the other. However, in female subjects with abnormal posture, there was a highly significant difference in left step length between subjects with back pain and those without (p=0.007).  The results of a multiple regression analysis indicate that posture has the greatest influence on left step length (B=4.135; 95% Confidence Interval 0.292-7.977). It is recommended that in the examination of low back pain an assessment be made of posture, step length and difference in step lengths.

Abstract

The wellbeing of medical students has emerged as a critical issue within medical education. High academic demands, prolonged study hours, and competitive environments contribute significantly to psychological distress, including depression, anxiety, and burnout. This systematic literature review synthesizes findings from 48 peer-reviewed studies published between January 2021 and April 2025 to explore the psychological, academic, and social determinants of wellbeing among medical students. Results indicate that maladaptive perfectionism, lack of emotional regulation, and inadequate support systems are key risk factors. Technological interventions, such as mobile-based mindfulness training and online counseling platforms, offer promising but limited solutions unless integrated into broader institutional frameworks. The review concludes by proposing a multidimensional model that combines curriculum reform, psychological resilience training, structured social support, and ethical use of technology to promote holistic student wellbeing.

Abstract

BackgroundAdolescence is a dynamic period of significant physical, emotional, and cognitive development, where individuals shape their identities and influence their mental health. Being vulnerable to various risk factors, including anxiety, adolescents often face mental disorders that can affect their overall well-being. With anxiety being a major concern in the global context as well as in Indonesia, this study aimed to determine self-esteem as a risk factor of developing anxiety among senior high school students. MethodsA cross-sectional study was conducted involving 162 senior high school students, using proportionate stratified cluster simple random sampling. Data were collected through the Rosenberg Self Esteem Scale and the Hamilton Anxiety Rating Scale questionnaires to measure self-esteem and anxiety levels, respectively. The full score for self-esteem was 10–40 points. The higher the score, the greater the self-esteem. Data was analyzed using multiple logistic regression. ResultsThe research findings indicate that adolescents experiencing anxiety amount to 51.9% and most of them indicated high self-esteem (61.1%). Multiple logistic regression test showed that low self-esteem (OR=2.21; 95% CI: 1.15-4.24) was the most influential risk factor of anxiety. However, there were no significant associations between anxiety and demographic factors such as gender, grade level, major of study, and parental income. ConclusionMost senior high school students experience anxiety, and lower self-esteem was the most influential risk factor of anxiety. The findings highlight the need for targeted interventions to boost self-esteem as a preventive measure against anxiety among senior high school students.

Abstract

Background Air pollution, particularly in urban areas such as West Jakarta, is a major public health concern. Longterm exposure to pollutants, including particulate matter (PM) 2.5, can lead to respiratory problems, including acute otolaryngologic diseases. Outdoor workers, such as those involved in urban infrastructure maintenance, are more vulnerable to these conditions. This study aimed to assess the relationship among air pollution levels, mucociliary clearance function, and the prevalence of acute otolaryngologic diseases among outdoor workers in West Jakarta. Methods A cross-sectional study was conducted among 120 Public Infrastructure and Facility Maintenance (PPSU) workers in the Cengkareng, Rawa Buaya, and Cengkareng Timur sub-districts. Air quality was assessed using data from nearby monitoring stations, measuring PM2.5 levels and the Air Quality Index (AQI). Health assessments included anamnesis, patient-reported outcome questionnaires, saccharin transit test, and otorhinolaryngologic endoscopic assessments. Results The average PM2.5 level was 57.58 μg/m³ (high risk for respiratory issues), and the AQI was 144.71 µg/m³ (unhealthy). The saccharin transit time test averaged 427.29 seconds, with a mean nasal floor length of 63.76 mm. The prevalence of acute rhinopharyngitis was 59.2%, rhinosinusitis 8.3%, occupational rhinitis 9.2%, and vitamin D insufficiency 67.5%. However, no significant correlation was found between air pollution exposure, mucociliary function, and acute otolaryngologic diseases (p > 0.05). Conclusions Despite high exposure to air pollution, no significant relationship was observed between air pollution, mucociliary clearance, and acute otolaryngologic diseases among PPSU workers. Further studies with larger sample sizes and longitudinal designs are needed.

Abstract

Background: Rapid advancements in digital technology have led to increased gadget use among adolescents, resulting in prolonged screen time among senior high school students. Although screen time supports learning and access to infomation, excessive use may reduce physical activity, impaired sleep quality, and limit social interaction, potentially affecting motor strength. Methods: This cross-sectional analytic observational study involved 228 senior high school students aged 15-18 years in Tangerang Regency, selected using stratified random sampling. Screen time was assessed using the Questionnaire for Screen Time of Adolescents (QueST), while motor strength was measured with a Camry handgrip dynamometer. Data were analyzed using the Chi-square test with SPSS. Results: Most respondents reported high screen time (73.24%) and low motor strength (58.77%). Students with high screen time were more likely to have low motor strength (70.66%), whereas those with low screen time more frequently demonstrated strong motor strength (59.26%). Chi-square analysis revealed a significant associations between screen time and motor strength (p<0.001). Conclusion: High screen time is significantly associated with reduced motor strength among senior high schools students. This highlight the importance of balanced screen use to support adolescents' physical development and promoting healthier daily activity patterns.
