Abstract
[Objective]To investigate the current status of preschool children's dietary supplement use and analyze its impact factors[Method]Totally 400 children aged 2-6 years who came for basic health checkups were selected by random stratified sampling from pediatric outpatient preventative care department of Shanxi Provincial Children's Hospital during 2022.07-2023.12.The information of dietary behaviors,physical activities,and dietary supplements intake were collected through questionnaires and data from physical examination and laboratory biochemical tests.Analysis were done to study the differences in taking behavior and its determinants based on different nutritional status.[Result]The survey showed that 40.8%of preschool children were taking dietary supplements,61.3%were tak-ing almost every day,with multivitamin-mineral complexes(23.0%),vitamin D(22.5%),and calcium(14.2%)as the main supplements.Children with normal whole blood zinc level had a higher prevalence of multivitamin-mineral and zinc intake than those below the normal range(P<0.05),underweight children had a higher prevalence of calcium intake than overweight and obese ones(P≤0.017).After adjust-ing for sex,annual per-capita household income,BMI-for-age and height-for-age,Logistic regression analysis suggested that caregivers tak-ing dietary supplements(OR=6.751,95%CI=2.947-15.464)and having better know-how about functional foods(OR=1.041,95%CI=1.009-1.076),children had picky eating habits(OR=2.497,95%CI=1.454-4.288)and normal serum zinc levels(OR=4.249,95%CI=2.301-7.846),were the promoting factors to increase intake behavior.An increase in age(OR=0.589,95%CI=0.353-0.983)and a number of meals out(OR=0.197,95%CI=1.009-1.076)were the obstructive factors.[Conclusion]Minimizing the number of meals out for preschool children and improving caregivers'scientific knowledge levels towards functional food may increase the rate of children's dietary supplements intake.关键词
