Bone fractures are a significant public health issue among elderly subjects. This study examines the impact of diet and vitamin D status on the risk of long bone fractures due to falls in elderly subjects in Vojvodina, Serbia. Conducted at the University Clinical Center of Vojvodina in autumn/winter 2022–2023, the study included 210 subjects >65 years: 105 (F: 80/M: 15) with long bone fractures due to falls and 105 (F: 80/M: 15) controls. Groups were similar regarding age and BMI. Dietary intakes (by two 24-h recalls) and serum vitamin D levels were analyzed. The fracture group had a significantly lower median daily vitamin D intake (1.4 μg/day vs. 5.8 μg/day), intake of calcium, energy, proteins, fats, fibers, dairy products, eggs, fish, edible fats/oils, and a higher intake of sweets (p < 0.001 for all). Serum vitamin D levels were significantly lower in the fracture group (40.0 nmol/L vs. 76.0 nmol/L, p < 0.001). Logistic regression identified serum vitamin D as the most important protective factor against fractures, and ROC curve analysis indicated that serum vitamin D levels > 50.5 nmol/L decreased fracture risk. Nutritional improvements (increased intake of vitamin D and protein sources such as fish, eggs, and dairy), increased sun exposure, and routine vitamin D supplementation during winter are advised.

it was to demonstrate the influencing factors of infant bone mineral density(BMD) and its correlation with serum 25-hydroxyvitamin D (25-(OH)D) in nursing mothers. 200 children aged 0 ~ 1 years were rolled into normal group (n=120) and abnormal group (n=80) regarding the results of ultrasound BMD examination. The sunshine duration of infants with different BMD and 25-(OH)D, calcium and phosphorus levels of nursing mothers were analyzed, and univariate and multivariate analyses of BMD were implemented. The results revealed that the sunshine duration and serum 25-(OH)D level of nursing mothers in abnormal group were inferior to those in normal group (P<0.05). Additionally, a notable positive correlation existedbetween sunshine duration, serum 25-(OH)D level of nursing mothers and BMD (r = 0.911 and 0.503, P<0.05). According to Logistic regression analysis, outdoor activity time 0 ~ 1 h/d, premature infants, and breastfeeding alone were independent risk factors (RFs) for abnormal BMD in infants, and vitamin D(VD) and calcium supplementation were independent protective factors (P<0.05). VD and calcium intake, adequate sunshine duration, mixed feeding, and increasing serum 25-(OH)D can reduce the occurrence of abnormal BMD in infants.
