Abstract:
Objective:To determine the nutritional status and associated factors of vitamin D in primary and middle school students in Shandong Province, so as to provide reference for developing targeted vitamin deficiency interventions.
Methods:From January to September 2021, using multi stage stratified random sampling, physical examinations and laboratory tests were carried out among 3 539 primary and middle school students in Shandong Province. Associated factors of vitamin D were analyzed by Logsitc regression analysis.
Results:The average vitamin D level among primary and middle school students was (17.56±6.65) ng/mL, while the deficiency and severe deficiency rate was 67.4%. Multivariate Logistic regression analysis showed that girls ( OR =1.95), students in junior high school ( OR =2.14) and senior high school ( OR =2.36) were at higher risk of vitamin D deficiency and severe deficiency ( P <0.05). Students from coastal areas ( OR =0.54), physical examination in summer and autumn ( OR = 0.74 ), and 35 g of egg intake per day ( OR =0.53), and with outdoor activity time greater than 60-120 min and >120 min ( OR =0.63, 0.48) had lower risk of vitamin D deficiency ( P <0.05).
Conclusions:The nutritional status of vitamin D among elementary and secondary school students in Shandong Province warrants further attention. Intervention measures such as nutritional education, healthy diet and prolonging outdoor activities should be promoted in primary and middle school students.
