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.

AbstractObjectivesThe prevalence of general overweight and obesity defined by body mass index criteria has greatly increased in Chinese children and adolescents in recent decades. However, few studies have considered the trend in abdominal obesity in Chinese children and adolescents. This study aimed to examine the secular trends in waist circumference (WC), waist-to-height ratio (WHtR) and the prevalence of abdominal obesity among Chinese children and adolescents aged 6–17 years from 1993 to 2015.MethodsA total of 11,985 children and adolescents aged 6–17 years participated in the China Health and Nutrition Survey, a continuous cross-sectional survey, conducted from 1993 to 2015. Abdominal obesity was defined as WC≥age- and sex-specific 90th percentile based on the reference from Chinese children and adolescents or WHtR≥0.50.ResultsAfter adjustment for age, sex and region, mean WC increased from 60.27 cm in 1993 to 64.31 cm in 2015 (p for trend <0.001), and mean WHtR increased from 0.430 to 0.434 (p for trend <0.05). The prevalence of abdominal obesity defined by WC reference increased from 5.0% in 1993 to 19.3% in 2015 and defined by WHtR reference increased from 6.4% in 1993 to 14.5% in 2015 (p for trend <0.001).ConclusionsThe prevalence of abdominal obesity among Chinese children and adolescents aged 6–17 years has increased between 1993 and 2015.

Dietary patterns represent the combined effects of foods, and illustrate efficaciously the impact of diet on health outcomes. Some findings of previous studies have limited applicability to Chinese children due to cultural factors. The presnt study was designed to identify dietary patterns and determine their relationships with obesity among Chinese children and adolescents. Data collected from 1282 children and adolescents aged 7–17 years from the 2011 China Health and Nutrition Survey (CHNS) were used. Dietary patterns were identified using factor analysis of data from three consecutive 24-h dietary recalls. Weight and height were measured following standard methods, and BMI was calculated. Three dietary patterns were identified: modern (high intakes of milk, fast foods and eggs), traditional north (high intakes of wheat, tubers and other cereals) and traditional south (high intakes of vegetables, rice and pork). After adjusting for some confounders and total energy intake, subjects in the highest quartiles of the modern and traditional north patterns were found to have significantly greater risk of obesity (OR 3·10, 95 % CI 1·52, 6·32, and OR 2·42, 95 % CI 1·34, 4·39, respectively). In conclusion, the modern dietary pattern and the traditional north dietary pattern were associated with higher risk of obesity. Promoting healthier eating patterns could help prevent obesity in Chinese children.

The growth status and weight status of Chinese children have experienced remarkable changes in the past decades. Using China Health and Nutrition Survey (CHNS) data, this paper examines the secular trends and disparity of the growth status and weight status in Chinese children and further investigates the impact of various family environments on children’s growth from 1991 to 2011. We found an increasing trend in standardized growth indicators (height, weight, and BMI), overweight, and obesity from 1991 to 2011. We also observed an increasing disparity in overweight and obesity over time. Family environments had a significant impact on children’s growth status and weight status. In particular, children that live in families with a small size, higher family income, better sanitary conditions, and with well-educated parents or overweight parents tended to be taller and heavier and have a higher BMI, lower risk of being underweight, and higher risk of exhibiting overweight and obesity. Further decomposition analysis showed that more than 70% of the disparity in standardized height, weight, and overweight and around 50% of the disparity in standardized BMI, underweight, and obesity could be attributed to heterogeneity in family environments. Moreover, the disparity associated with family environments tended to increase over time.

Chinese Children And Adolescents

China is experiencing significant public health challenges related to social and demographic transitions and lifestyle transformations following unprecedented economic reforms four decades ago. Of particular public health concern is the fourfold increase in overweight and obesity rates in the nation’s youth population, coupled with the low prevalence of adolescents meeting recommended levels of physical activity. Improving the overall health of China’s more than 170 million children and adolescents has become a national priority. However, advancing nationwide health initiatives and physical activity promotion in this population has been hampered by the lack of a population-specific and culturally relevant consensus on recommendations for achieving these ends. To address this deficiency and inform policies to achieve Healthy China 2030 goals, a panel of Chinese experts, complemented by international professionals, developed this consensus statement. The consensus was achieved through an iterative process that began with a literature search from electronic databases; in-depth reviews, conducted by a steering committee, of the resulting articles; and panel group evaluations and discussions in the form of email correspondence, conference calls and written communications. Ultimately, the panel agreed on 10 major themes with strong scientific evidence that, in children and adolescents aged 6–17, participating in moderate to vigorous physical activities led to multiple positive health outcomes. Our consensus statement also (1) highlights major challenges in promoting physical activity, (2) identifies future research that addresses current knowledge gaps, and (3) provides recommendations for teachers, education experts, parents and policymakers for promoting physical activity among Chinese school-aged children and adolescents. This consensus statement aligns with international efforts to develop global physical activity guidelines to promote physical activity and health and prevent lifestyle-related diseases in children and adolescents. More importantly, it provides a foundation for developing culturally appropriate and effective physical activity interventions, health promotion strategies and policy initiatives to improve the health of Chinese children and adolescents.

Double Burden Of Malnutrition

Abstract Objectives Disease and lifestyle patterns have been changing rapidly worldwide including Africa due to recent changes in economic growth and urbanization. However, research related to the effects of these changes on nutrition status in Africa is limited. This study investigated the shifts in nutritional status (undernutrition, overweight, obesity) in children and adults in 4 carefully selected low-, middle- and high income countries in Africa, identified factors associated with the shifts, and provided recommendations for future work. Methods Malawi, Kenya, Ghana, and South Africa were selected based on their economic status, population size, urbanization, etc. Nationally representative data was obtained from sources such as 2017 Global Nutrition Report, Demographic Health Surveys (DHSs), Food and Agriculture Organization Corporate Statistical Database (FAOSTAT), and World Health Organization (WHO). The prevalence of underweight, overweight and obesity (ov/ob), and some ratios were assessed and compared across the countries between 1998 and 2016. Results Varied nutrition status and shifts were observed among the countries during 1998–2016. Countries with the higher economic status also had higher prevalence and faster increasing trends of ov/ob. South Africa had the highest GDP and highest ov/ob rates in children <5, children 5-18, and adults >18 (13.3%, 24.7%, and 51.9% respectively). Malawi, with the lowest GDP, had the highest stunting rate (37%). In each country, but most notably in South Africa, trends indicated the increasing ov/ob rate (11.8%) was much greater than the declining underweight rate (2.4%). Slight declines in overweight in children under 5 years were observed in Malawi, Kenya, and Ghana, which might be due to reduced stunting rates. Sex differences existed in older children and adults, with higher rates of ov/ob in females and undernutrition among males. Conclusions Nutrition shifts, heavily influenced by economic development, are rapidly occurring in sub-Saharan Africa. The double-burden of malnutrition posts prioritization challenges for policymakers. Because undernutrition is now a declining issue, the focus should be shifted towards prevention of obesity, at least in higher income countries in Africa. Funding Sources The study is funded in part by a center grant from the US National Institutes of Health (NIH, U54HD070725).

This study aimed to investigate the diagnostic accuracy of body mass index- (BMI-) based and waist circumference- (WC-) based references for childhood overweight and obesity in screening overfat individuals among 2134 Chinese children and adolescents. In this study, overfat status was defined as over 25% body fat for boys and over 30% for girls. Childhood obesity or overweight was defined by four BMI-based references and two WC-based references. All BMI-based references for obesity showed low sensitivity (SE) (0.128–0.473) but high specificity (SP) (0.971–0.998) in detecting overfat individuals in the current population. SE values increased from 0.493 to 0.881 when BMI- and WC-based references for overweight were used to detect overfat individuals. All references for overweight showed high SP rates (0.816–0.966). To improve diagnostic accuracy for childhood obesity, further studies may define a cut-off value for childhood obesity specific for a local population and ethnicity by using health-related overfat data.
