Abstract

Objective To explore the relations between dietary diversity and micronutrient intakes in school-age children in a rural area of China,in order to provide scientific basis for guiding children′s scientific diet to promote children′s health. Methods Totally 442 children aged 6-7 years in Sheyang Mini Birth Cohort Study were enrolled.24 h dietary recall survey was conducted to evaluate nutritional status.Micronutrient intakes and dietary diversity were calculated according to Chinese Food Composition Tables (CFCT) 2004 and 2009.Weight and height of children were measured and obesity was defined based on sex- and age-standardized body mass index.Multivariable regression models were preformed to examine associations of dietary diversity with micronutrient intakes and childhood obesity. Results The intakes of micronutrients was lower than age-specific Chinese Dietary Reference Intakes (DRIs) (2013 edition).Mean values of three Dietary Diversity Scores were lower than those in several studies (DDS:6.69±1.59; DDS₁₀:4.94±1.51; FVS:16.79±7.53) in China.Dietary Diversity Score was significantly positively associated with micronutrients intake (DDS:β=0.14-1.28; DDS₁₀:β=0.17-1.58; FVS:β=0.04-0.25,P<0.05).No significant association was observed between dietary diversity and childhood obesity. Conclusions The findings suggest that Dietary Diversity Score could act as an effective indicator for micronutrient intake in children.
