Summary: The study found that vitamin D deficiency rates among young African children were 0.6% and 7.8%, with factors such as country, age, season, inflammation, and malaria influencing the levels. In addition, variations in the GC gene were associated with vitamin D levels.

Summary: This study found that hypovitaminosis D is highly prevalent among pregnant rural Bangladeshi women. Parity and gestational age are common risk factors for vitamin D deficiency and insufficiency, while a husband's occupation and anaemia status may predict vitamin D insufficiency. Younger age and sub-optimal vitamin A status are risk factors for vitamin D deficiency in this population.

Summary: This study investigated the potential mediating role of BMI in the association between SSB intake and 25(OH)D. The findings suggest that high total sugar intake from SSB and BMI independently contribute to lower 25(OH)D, and BMI mediates the inverse association between total sugar intake from SSB and 25(OH)D. Furthermore, an increased risk of having vitamin D deficiency was found in the population who consumed higher levels of sugar from SSB or soda drinks.

Summary: This review aimed to estimate the prevalence of vitamin D deficiency in South American populations. A total of 96 studies involving 227,758 participants were included. The overall prevalence of vitamin D deficiency was found to be 34.76%. Age, sex, country, latitude, season, and year of publication were factors associated with the prevalence rates. Therefore, public health strategies should address the prevention, detection, and treatment of vitamin D deficiency.

Summary: The study finds that there is a negative correlation between vitamin D levels and depression, and a positive correlation between age and depression. Additionally, vitamin D deficiency and older age both increase the risk of depression.

Summary: This review assesses the relationship between vitamin D deficiency and H. pylori infection, finding that vitamin D deficiency may be a potential risk factor for H. pylori infection and is directly linked to eradication failure. An inverse linear relationship exists between vitamin D status and gastric cancer risk, but the involvement of H. pylori in this correlation is still uncertain. Further population-based studies are needed to explore this subject in more depth.

Summary: The study found a high prevalence of vitamin D deficiency in South African infants, with factors such as study site, socioeconomic status, and gender being associated with serum 25(OH)D-3 levels. Birth in winter and breastfeeding were identified as the strongest predictors of lower vitamin D concentrations.

Summary: The study revealed a high prevalence of vitamin D deficiency in critically ill patients in Northern Taiwan, with factors such as age, gender, albumin levels, PTH levels, and SOFA scores significantly associated with this deficiency.

Summary: This study investigated the prevalence of vitamin D deficiency and its risk factors in children and adolescents aged 10 to 19. The results showed a high prevalence of vitamin D deficiency, especially among boys and overweight/obese individuals. Additionally, there was a significant association between vitamin D deficiency and low serum levels of magnesium and phosphate.

Summary: The prevalence of biochemical osteomalacia is very low, even in individuals with 25OHD levels below 25 nmol/L, with all cases of osteomalacia having 25OHD levels <= 18 nmol/L before supplementation.

Summary: Based on NHANES data, vitamin D deficiency is still prevalent in the United States, especially among non-Hispanic black Americans, women, individuals aged 20-29, and during winter. From 2001 to 2018, there was a slight decrease in the prevalence of moderate VDD and VDI, while there was a slight increase in vitamin D sufficiency.

Summary: This matched cohort study aimed to investigate the relationship between vitamin D deficiency (VDD) and post-stroke depression (PSD). The results revealed no significant link between VDD and PSD risk during the 3-month and 12-month follow-up periods. However, further extensive studies are necessary to explore the potential protective effects of vitamin D against PSD.

Summary: Vitamin D is an immune modulator that affects infection susceptibility. The relationship between vitamin D deficiency and mortality in sepsis patients remains unclear. Adequate vitamin D concentration may reduce mortality in sepsis patients with severe deficiency.
