Effect of cholecalciferol supplementation on hand grip strength, walking speed, and expression of vitamin D receptor, interleukin-6, and insulin-like growth factor-1 in monocyte in pre-frail older adults: A randomized double-blind placebo-controlled trial.

AIM: To investigate the effect of cholecalciferol supplementation on hand grip strength, walking speed, and expression of vitamin D receptor (VDR), interleukine-6 (IL-6) and insulin-like growth factor-1 (IGF-1) in monocyte in pre-frail older adults. METHODS: We conducted a randomized double-blinded placebo-controlled clinical trial for 12 weeks, involving 120 pre-frail older adults who were randomized to the cholecalciferol group (cholecalciferol 4000 IU/day) or the placebo group. All subjects were given calcium lactate 500 mg/day. Hand grip strength and walking speed, as primary outcomes, were analyzed using intention-to-treat analysis. The expression of VDR, IGF-1 and IL-6 in monocytes, as secondary outcomes, were analyzed using per-protocol analysis. RESULTS: After a 12-week intervention, there was a significant increase in serum 25(OH)D levels in both groups, with the increase being higher in the cholecalciferol group than in the placebo group (49.05 vs. 24.01 ng/mL; P < 0.001). No statistically significant differences were observed in hand grip strength (P = 0.228) and walking speed (P = 0.734) between the groups. There were no differences in the expression of VDR (P = 0.513), IL-6 (P = 0.509), and IGF-1 (P = 0.503) monocytes between the groups. CONCLUSIONS: Cholecalciferol supplementation for 12 weeks increased serum 25(OH)D levels among pre-frail older adults. However, it did not improve hand grip strength and walking speed, and nor did it change the expression of VDR, IL-6, and IGF-1 in monocytes. Geriatr Gerontol Int 2024; 24: 554-562.

Vitamin D Levels in Pre-frail Older Adults and Its Correlation with Hand Grip Strength.

BACKGROUND: Vitamin D deficiency is frequent in older adults and associated with poor musculoskeletal function. The prevalence of pre-frailty is also high in older persons, who may proceed to a frail state. This study aimed to determine the vitamin D levels in pre-frail older adults and its correlation with hand grip strength. METHODS: A cross-sectional study was conducted on older adults (age > 60 years) with a pre-frail condition who were visiting the outpatient geriatric clinic at Cipto Mangunkusumo Hospital in Jakarta, Indonesia. Serum levels of vitamin D, measured as 25(OH)D, were determined by enzyme-linked immunosorbent assay (ELISA), and hand grip strength was measured using a Jamar hydraulic dynamometer. Correlations between vitamin D levels and hand grip strength were evaluated by Spearman's rank correlation coefficient. Multiple linear regression analysis was carried out to assess contribution of variables that influence hand grip strength. RESULTS: Of 95 pre-frail older adults (mean age 70.08 ± 5.35 years), 67.4% were female,  and the median vitamin D level was 17.91 (interquartile range/IQR 13.68-26.36) ng/mL. Overall, 11.6% of the participants had normal vitamin D levels, whereas 34.7% and 53.7% had insufficient and deficient levels, respectively. Females were more likely to have inadequacy of vitamin D than males.  Those with vitamin D deficiency tended to have a higher body mass index (BMI) and lower vitamin D intake than normal levels. A significant correlation between serum vitamin D levels and hand grip strength was observed (r = 0.283; P = 0.006). After adjusting for age, comorbidities, nutritional status, functional status, BMI, protein intake, and sun exposure score, regression analysis between hand grip strength and vitamin D levels gave standard coefficient beta = 0.255 (P = 0.013). CONCLUSION: In this study, pre-frail older adults had a high proportion of deficient and insufficient vitamin D levels, and a significant correlation was found between serum vitamin D levels and hand grip strength.

A partnership-oriented and culturally-sensitive communication style of doctors can impact the health outcomes of patients with chronic illnesses in Indonesia.

OBJECTIVES: A partnership-oriented communication style is globally recommended for medical practice. A culturally-sensitive doctor-patient communication guideline is also needed for Southeast Asia. The 'Greet-Invite-Discuss' guideline was established and tested with primary care doctors and their patients in Indonesia. METHODS: In this mixed-methods study, doctors were trained according to the 'Greet-Invite-Discuss' guideline, while patients received standard treatment. Two groups of fifteen doctors were assigned to have consultations with 45 patients with hypertension or 51 patients with type-2 diabetes mellitus. Doctors' self-assessment and patients' perceptions and their clinical outcomes were longitudinally measured. Six focus group discussions were conducted to explore doctors' and patients' experiences. RESULTS: Doctors' self-assessments and patients' perceptions of doctors' communication skills increased significantly (p < 0.05). Moreover, patients' blood pressure or fasting blood glucose levels decreased significantly (p < 0.05), except the two-hour blood glucose levels (NS). Qualitatively, doctors demonstrated more partnership and culturally-sensitive communication, and patients expressed more satisfaction, increased comprehension and self-management, of their chronic illnesses. CONCLUSIONS: The 'Greet-Invite-Discuss' guideline was useful for primary care doctors for a more partnership-oriented and culturally-sensitive communication with patients in chronic care management. PRACTICE IMPLICATIONS: Using a partnership-oriented and culturally-sensitive communication guideline, doctors can improve their communication skills with their patients towards optimum health outcomes.

Profile of food and nutrient intake among Indonesian elderly population and factors associated with energy intake: a multi-centre study.

AIM: to obtain profile of food and nutrient intake in Indonesian elderly population and factors associated with energy intake. METHODS: multi-center cross sectional study in 13 hospitals across Indonesia was conducted among 387 elderly who had attended geriatric clinics. Data collected including demographic characteristics, functional status, cognitive status, mental status, nutritional status, food intake, present activities, and data on chronic diseases. Chi square and logistic regression tests were performed to analyze the data. RESULTS: most of subjects (58.4%) were women and had educational background senior high school or higher degree (61.1%). The average of energy intake was 1266.74 (336.51) kilocalories. Calcium and protein intake were below the recommended of dietary allowance. female sex (OR 0.23; 95% CI 0.139-0.390) and osteoporotic subjects (OR 0.48; 95% CI 0.25-0.93) have lower risk for having <80% RDA daily energy intake, while lower educational level (OR 1.96; 95% CI 1.21-3.18) has higher risk for having <80% RDA daily energy intake. CONCLUSION: total energy intake were inadequate in the elderly. Female sex and osteoporotic subjects have lower risk for having <80% RDA daily energy intake, while lower educational level has higher risk for having <80% RDA daily energy intake.
