Summary: Low serum 25-hydroxyvitamin D levels are associated with altered lipid profiles, inflammation, and cardiometabolic risks in young healthy adults, particularly in populations with high rates of deficiency and insufficiency. The Monocyte to HDL-cholesterol ratio (MHR) has emerged as a potential novel marker of inflammation that could help predict cardiovascular diseases among this demographic.

Summary: This study aimed to obtain epidemiological data on vitamin D levels for the pediatric population in Japan. The results showed that vitamin D deficiency and insufficiency are very common among 2-year-old Japanese children, with factors such as sex, season, and latitude affecting serum 25(OH) D concentrations.

Summary: There is a strong positive linear correlation between free 25(OH)D (f25(OH)D) and total 25(OH)D, making them useful for assessing vitamin D levels. The recommended threshold level for f25(OH)D is 8.499 pg/mL, corresponding to a target concentration of at least 30 ng/mL for t25(OH)D. The upper limit for vitamin D is still unclear, with most experts favoring a upper limit of 100 ng/mL for t25(OH)D.

Summary: This study investigates the association between vitamin D deficiency and COVID-19 severity among survivors. The findings show a correlation between vitamin D deficiency and severe cases, as well as the presence of post-acute sequelae of COVID-19 (PASC) among survivors. Gender and BMI are also found to be related to vitamin D levels, but not to the presence of PASC.

Summary: This study found a quasi J-shaped relationship between serum circulating 25-hydroxyvitamin D (25(OH)D) level and risk of recurrent stroke in patients with a stroke history. The lowest risk of recurrent stroke was observed at a 25(OH)D level of approximately 60 nmol/L, which was associated with a 48% reduction in risk compared to a level of 10 nmol/L.

Summary: This study aimed to evaluate the association between dietary vitamin D intake and serum vitamin D concentrations with cognitive performance in older Americans. The results showed a positive association between dietary vitamin D intake, serum total 25-hydroxyvitamin D, and cognitive performance, with no significant gender differences in the associations. Further research is needed to clarify the effects of dietary vitamin D intake and specific serum D concentrations on cognitive performance.

Summary: The correlation between maternal vitamin D concentrations and birth outcomes is conflicting. This study found that the maternal vitamin D metabolite ratio, specifically VMR2, is associated with neonatal anthropometric data regardless of 25(OH)D concentrations. Accurate measurement of vitamin D metabolites can help understand the effects of vitamin D on birth outcomes.

Summary: This study evaluated the association between 25(OH)D (total, free, and bioavailable) with adiposity and metabolic traits. The findings suggest that free and bioavailable 25(OH)D do not offer additional advantages over total 25(OH)D regarding its association with adiposity and several metabolic traits in Mexican adults.

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 study analyzed the data from UAE Healthy Future Study to investigate the association between serum vitamin D levels and body fat composition as well as BMI among Emiratis. The results showed a significant negative association between serum vitamin D levels and body fat composition at intermediate percentiles, and a negative association between serum vitamin D levels and BMI at the median.

Summary: This study confirmed that 25(OH)D3 can be detected in human hair, but further investigations are needed to determine its use as a biomarker since no correlation was found between serum 25(OH)D3 concentrations, supplementation, sun exposure, and hair 25(OH)D3 concentrations levels.

Summary: The purpose of this study was to investigate the intake and sources of vitamin D, as well as the determinants of serum 25-hydroxyvitamin D (S-25(OH)D) in Finnish adolescents. The results showed that most adolescents had vitamin D intake at the recommended level, although a quarter did not meet the recommended intake and almost a third had low levels of S-25(OH)D. The main determinants of S-25(OH)D were vitamin D intake from supplements, consumption of milk products, consumption of meat products, travels to sunny countries, and average daylight time.

Summary: The study found that the low vitamin D status in recent lactating mothers may have decreased the concentrations of vitamin D and 25OHD in breast milk, compared to the 1980s. This has important implications for improving the vitamin D status of lactating mothers and infants.

Summary: This study found that disadvantaged socioeconomic position is an independent determinant of probable sarcopenia in community-dwelling older adults. In addition to SEP, factors such as increased age, low physical activity, comorbidity, and osteoarthritis were significantly associated with an increased likelihood of probable sarcopenia.

Summary: This study aimed to explore the experience and perceptions of Health Care Assistants (HCAs) who delivered the Care to Move (CTM) program to older adults. The findings suggest that despite challenges such as limited time and task-orientated care, most HCAs had a positive perception of the program's focus on movement prompts and motivators, as well as its fit within home support services.

Summary: The purpose of this study was to explore older adults' experiences of engaging in Care to Move (CTM) within their home care support services and identify the strengths and barriers of participating in CTM from their perspective. The findings showed that older adults benefitted from CTM in terms of physical and psychological well-being, but subjective frailty and self-reported multi-morbidity influenced their overall engagement. The continuity of care staff and the negative impact of COVID-19 on older adults' health were identified as barriers to implementing CTM.

Summary: Elderly individuals living in socioeconomically disadvantaged areas experience higher rates of polypharmacy, physical dependency, hospitalization-associated dependency, and have a younger average age of needing state home support compared to those in more affluent settings. These findings suggest that health inequalities persist in older populations and highlight the need for further research and community-based health and social care initiatives.

Summary: This study found a significant association between low body mass index (BMI) and probable sarcopenia, highlighting a high-risk group. However, there were conflicting findings regarding the association between overweight/obesity and probable sarcopenia. It is recommended to assess all older adults at risk of probable sarcopenia, including those with overweight/obesity, to prevent underdetection or the double burden of obesity and sarcopenia.

Summary: This study aimed to estimate the prevalence of sarcopenia and its association with socioeconomic position (SEP). The findings showed a higher prevalence of sarcopenia in adults from disadvantaged SEP groups. Disadvantaged SEP, along with older age, physical inactivity, underweight BMI, chronic conditions, osteoarthritis, and minority group ethnicity were identified as independent predictors of sarcopenia.
