ABSTRACT
Objective To explore the relationship between body muscle mass and body mass index of school-age children and their growth differences in different seasons. Methods A total of 526 cases of preschool children who came to Hengshui People's Hospital for examination from June 2018 to June 2020 were selected as observation objects, including 300 males and 226 females, aged 6-11 years old, with an average age of (8.2 years ±0.2 years). According to the body mass index (BMI), children are divided into normal body weight, overweight weight and obese groups. According to the season, preschool children were divided into four groups, spring group, summer group, autumn group, and winter group, with 131 cases in each group. The physique of preschool children was tested, and the serum 25(OH)D was detected at the same time, the body muscle mass was measured by the bioelectrical impedance method, and the whole body muscle mass index was calculated. Multi-factor linear regression was used to analyze the relationship between vitamin D nutritional status and muscle mass index ; To study the average vitamin D content of children and the differences in different seasons. Results There were 396 children with normal BMI, 90 were overweight, and 40 were obese. The children's normal weight, overweight, and obesity were divided into groups. According to the increase in BMI, the normal vitamin level group, overweight group, and obesity group also decreased, and the difference was statistically significant (P0.05). Compared with the vitamin D deficiency and deficiency groups, the number of children with sufficient vitamin D is also increasing, and the children with sufficient vitamin D have a fixed-point visit to the MMI. According to the analysis results, it is observed that there is a statistically significant difference in vitamin D nutrition and body muscle mass levels (P<0.05). The serum 25(OH)D levels of children in summer and autumn were significantly higher than those in spring and winter, and the difference was statistically significant (P<0.05). Conclusion The body muscle mass and body mass index of preschool children have a significant relationship with 25(OH)D. When 25(OH)D is sufficient, higher body muscle mass can be obtained and the body mass index can be decreased. The growth difference in different seasons is manifested in the higher 25(OH)D in summer, which is more conducive to the growth and development of preschool children.
