    Abstract: Emerging evidence suggests sarcopenia, which is involved in the serum vitamin D deficiency and development of abnormal muscle metabolism, is predominately centered in the general older population. In the present study, we aimed to explore the relationship between the level of serum vitamin D and irisin concentrations in the older adults with sarcopenia. Methods A cross-sectional study was conducted which included 422 sarcopenia participants (146 males and 276 females). Sarcopenia was assessed according to the recommended diagnostic criteria of the Asia Working Group for Sarcopenia (AWGS). The levels of serum 25-hydroxyvitamin D (25(OH)D), 25-hydroxyvitamin D 2 (25(OH)D 2 ) and 25-hydroxyvitamin D 3 (25(OH)D 3 ) were determined by LC-MS/MS. Irisin levels were measured by enzyme-linked immunosorbent assay (ELISA). The relationship between serum concentration of vitamin D and irisin were determined using multiple linear regression analysis. Results After adjustment for potential confounding factors, a significant and positive relationship between changes in irisin across 25(OH)D, and 25(OH)D 3 was observed (standard regression coefficients of 0.150 and 0.151, respectively, P & lt; 0.05). However, no significant relationship was observed between serum vitamin D concentrations and irisin levels in males. Conclusions This study demonstrated that a higher level of serum vitamin D is independently related to the increment of irisin in sarcopenia females, not in males. These investigations need to be verified in other large-scale prospective studies.

    Abstract: This study aimed to estimate the status of complementary feeding (CF) and its associated factors among 6–23-month breastfed infants and young children (IYC). We used secondary data from the China Nutrition Improvement Project on Children in Poor Areas in 2018. The status of CF was provided by parents of IYC through 24-h dietary recall. The study included 13,972 6–23-month-old breastfed IYC comprising 24.7% 6–8-month, 28.5% 9–11-month, 31.4% 12–17-month, and 18–23-month IYC. The highest percentage of IYC introduced to cereal foods was 84.8%. Nearly, 83.6% of 6–8-month infants were introduced to solid or semi-solid food. The prevalence of meeting requirements of non-dairy animal source food and minimum acceptable diet (MAD) was 75.3 and 35.1% of 6–23-month IYC, respectively, and was significantly higher in older than younger IYC ( p & lt; 0.001). Age of IYC, education level of parents, paternal employment, and nutrition knowledge of parents were positively associated factors for the prevalence of meeting requirements of MAD, and diarrhea at 2 weeks and maternal employment were negatively associated with MAD. Totally, the prevalence of meeting the requirements of MAD was relatively lower in breastfed IYC. The government should scale up appropriate CF with consideration of food availability.
