Abstract

Studies on the intraindividual double burden of malnutrition (DBM) among Chinese children and adolescents were lacking. This study aimed to analyze the prevalence of intraindividual DBM defined as the coexistence of overweight/obesity and dietary micronutrient intake insufficiency and investigate dietary micronutrient intake in Chinese children and adolescents. Using data from the 2015 China Health and Nutrition Survey (CHNS), 1555 children and adolescents aged 6 to 17 years were selected as the subjects. We referred to China Food Composition to calculate the intakes of 11 selected dietary micronutrients from diet data collected by consecutive three days of 24 h recalls combined with household weighing of seasonings. We used the Chinese estimated average requirement (EARs) as a cutoff to define the dietary micronutrients deficiency, and applied the body-mass-index-for-age Z-scores (BAZ) of World Health Organization (WHO) child growth standards to define the category of body weight. Among the subjects in present study, the prevalence of overweight and obesity was 15.43% and 11.06%, respectively, and 26.24% of the subjects had undergone intraindividual DBM. The results suggest that the prevalence of intraindividual DBM and dietary micronutrients deficiency in Chinese children and adolescents is high.

Highlights

Published: 3 September 2021Malnutrition persists at unacceptably high levels on a global scale; one in every nine people in the world is hungry, and one in every three is overweight or obese [1]
Intraindividual double burden of malnutrition (DBM) was observed in 26.24% of children and adolescents, along with 4.95% of subjects affected by underweight and dietary micronutrient intake deficiency concurrently
This study explored the DBM among Chinese children and adolescents aged 6 to 17 years using the China Health and Nutrition Survey (CHNS) 2015, and examined whether daily dietary of micronutrient status varies by body weight categories

Summary

Introduction

Published: 3 September 2021Malnutrition persists at unacceptably high levels on a global scale; one in every nine people in the world is hungry, and one in every three is overweight or obese [1]. More and more countries experience the double burden of malnutrition (DBM), which is characterized by the coexistence of undernutrition (i.e., micronutrient deficiencies, underweight and childhood stunting and wasting) alongside overweight, obesity, or other diet-related noncommunicable diseases [2]. Another study highlighted the DBM of Vietnam children in 2011 with the dietary intake insufficiency of iron, vitamin A, vitamin B1 and vitamin C, and the prevalence of overweight, obesity and underweight [4]. China has experienced a seismic shift from a high prevalence of underweight to increasing overweight and obesity over the past few decades [5,6,7], the prevalence of overweight/obesity increased from 5.0% and 1.7% in 1991–1995 to 11.7% and. The dietary changes are enormous in China [10,11]
