Abstract:
Objective:To investigate the vitamin D levels in children aged 1 year in Shaoxing City, Zhejiang Province, so as to provide the basis for prevention and treatment of vitamin D deficiency in children and promoting their health.
Methods:The 1-year-old children who underwent health examinations at the Department of Child Health Care of Shaoxing Maternal and Child Health Care Hospital from September 2023 to August 2024 were selected. Basic information of the children was collected through the medical record information system, and their length and weight were measured. The length, weight and nutritional status were evaluated according to the Technical Specifications for the Management of Nutritional Diseases in Children. Serum 25-hydroxyvitamin D [25- (OH) D] levels were measured using electrochemiluminescence assay, and vitamin D levels were assessed based on the fifth edition of Child Health Care. The vitamin D levels were analyzed among the children with different genders, testing months, and growth status.
Results:A total of 2 245 children were recruited, including 1 189 boys (52.96%) and 1 056 girls (47.04%). The median serum 25- (OH) D level was 39.98 (interquartile range, 16.63) ng/mL. Vitamin D insufficiency was observed in 279 children, with an insufficiency rate of 12.43%. The median serum 25- (OH) D level in boys was 39.26 (interquartile range, 17.75) ng/mL, which was lower than that in girls at 41.39 (17.75) ng/mL (P<0.05). The vitamin D insufficiency rate was 13.04% in boys and 11.74% in girls, with no statistically significant difference (P>0.05). The lowest vitamin D insufficiency rate was observed in August at 4.95%, while the highest rate was in September at 23.89%, showing the statistically significant difference across testing months (P<0.05). The children with above-average length ratings, higher weight ratings and obesity had higher vitamin D insufficiency rates, at 17.29%, 20.86% and 20.88%, respectively. The vitamin D insufficiency rate increased with higher weight and nutritional status ratings (both P<0.05), but no significant change was observed with higher length ratings (P>0.05).
Conclusions:The vitamin D insufficiency rate among 1-year-old children in Shaoxing City was 12.43%, with variations observed in different testing months, weight and nutritional status. Targeted prevention and intervention measures should be implemented to address these differences.
