Abstract

Background: The population of the elderly in Indonesia has increased significantly in recent years. The incidence of falls is influenced by postural balance. Vitamin D and hemoglobin deficiency are associated with decreased muscle function and postural balance. This study is to investigate the relationship between vitamin D and hemoglobin levels with postural balance in the elderly. Methods: The study used a cross-sectional design with the participation of 33 patients (aged 64.94±5.42 years). The study sample was elderly individuals who fulfilled the inclusion criteria at Semarang Elderly Posyandu. Patients performed postural balance test, with Sharpened romberg and tandem gait test. The examination of vitamin D and hemoglobin was taken from the patient's venous blood. Vitamin D was measured using ELISA. Results: The results of the independent sample t-test analytic test revealed a P value of vitamin D (0.007) and a P value of hemoglobin of (0.021) (p<0.05). There is a meaningful relationship between vitamin D and hemoglobin levels with postural balance in the elderly.. Conclusion: Decreasing Haemoglobine and Vitamin D impair the postural balance.

Abstract

Background: The elderly, aged 60 and above, are expected to increase in number in the coming years. Aging brings about various changes, impacting both physical and mental health. Proper protein intake and exercise can boost muscle protein synthesis, while maintaining optimal vitamin D levels is crucial. Research is necessary to explore vitamin D's impact on elderly muscle mass.Objective: This study aims to investigate the effect of adding vitamin d supplementation to protein and exercise on handgrip strength in healthy elderly.Materials and Methods: 24 participants were randomized in a double-blinded, pilot study ages 60- 80 years Subjects were divided into two groups. Group 1 was given interventions of vitamin D supplementation 1000 UI/day combining soy + oats milk as a protein and exercise. The second group was given intervention of soy+ oats milk protein, and exercise. The intervention program was administered for 8 weeks. Data comparison whitin and between groups were analyzed by Independent T-test, Mann-Whitney, and Paired T-testResults: Data from all participants was analyzed, before and after interventions of handgrip was increased in both of groups from a mean of 17.18kg to 18.06kg for the right hand and 15.17kg to 18.26kg for the left hand in Group 1, 13.80kg to 16.86kg for the right hand and 15.45kg to 17.32kg for the left hand in Group 2. Results of the difference test analysis between the two groups (ANOVA t = 0.548, P= 0172) showed no difference between group 1 and group 2.Conclusion: In this study, there was no effect of adding vitamin D supplementation on handgrip at healthy elderly participants.

Abstract

Background: Intermittent Fasting (IF) is a type of fasting where a person alternates between fasting and eating within specific time intervals. Medical students tend to have poorer sleep quality compared to students from other faculties. This can negatively affect their academic performance, as well as their physical and mental health. While intermittent fasting is known to offer various health benefits, its effect on sleep quality in medical students has not been widely studied. Therefore, further research is needed to explore the impact of intermittent fasting on sleep quality among medical students. Objective: To determine the effect of intermittent fasting on the sleep quality of medical students. Methods: This study employed a quasi-experimental design with a one-group pretest-posttest design. The sample consisted of 24 medical students from the Faculty of Medicine, Diponegoro University, Semarang. The sample was selected using purposive sampling based on predetermined criteria. In this study, the intervention involved intermittent fasting using the 12:12 Time Restricted Feeding method. Fasting started from 6 PM to 6 AM on Mondays, Wednesdays, and Fridays for three consecutive weeks. Data analysis on sleep quality before and after the intervention was conducted using the Paired Sample T-Test. The correlation between confounding variables, such as stress levels and physical activity levels, and sleep quality was analyzed using Spearman's correlation test. Results: There was a significant decrease in the global PSQI score after the participants underwent intermittent fasting compared to before, with a p-value < 0.05 (p = 0.05 (p = 0.493). Conclusion: Intermittent fasting can improve the sleep quality of medical students.
