Abstract

Abstract

Objective To investigate the nutritional status and associated factors of vitamin D among children aged 0 to 12 years old in Chongqing. Methods From January 2019 to December 2021, 1 877 children aged 0-6 years who received regular child health care were randomly selected from Chongqing maternal and child health hospital, and 707 school-age children were also selected from three primary school in Chongqing for investigation. The serum sample were collected for detecting serum 25-(OH)-D level by chemiluminescence method, and the possible influencing factors of vitamin D deficiency (VDD) were analyzed. Results The average serum 25-(OH)-D concentration of children was (39.9±9.1) ng/mL with the positive rate of VDD was 14.59%. There were significant differences of VDD positive rate in different age, visiting time, visiting season, body shape, outdoor activity time and vitamin D supplementation (0-3 years old vs 4-6 years old vs 7-12 years old: 14.73% vs 22.19% vs 10.47%; visiting season: spring vs summer vs autumn vs winter: 12.97% vs 10.65% vs 14.86% vs 21.33%; pre COVID-19 epidemic vs post COVID-19 epidemic: 11.18% vs 17.08%; underweight or normal vs overweight or obesity: 12.34% vs 26.13%; adequate outdoor activity time vs inadequate: 11.84% vs 16.27%; regular vitamin D supplementation vs irregular vitamin D supplementation: 11.71% vs 15.62%)(χ²=26.17, 17.59, 30.98, 53.74, 9.60, 6.17, P < 0.05). Underweight or normal body weight, sufficient outdoor activities and regular vitamin D supplementation were associated with less vitamin D deficiency with OR(OR95%CI) at 0.68(0.55-0.84), 0.57(0.25-0.77) and 0.62(0.44-0.85)(P < 0.05). Conclusion The prevalence of VDD among preschool and school-age children is high in Chongqing. Integrated prevention and control strategies incluing overweight or obesity control, increasing outdoor activities and oral vitamin D supplements should be taken.
