Trend in physical growth among Chinese urban students: Results from five national successive cross-sectional surveys within the past two decades
Objectives
To examine the orientation, magnitude, and pace of secular trends in body height, weight, and body mass index (BMI) among Chinese urban students aged 7–18 years from 2000 to 2019.
Methods
Data were extracted from Chinese urban students aged 7–18 years from the Chinese National Surveillance on Students' Constitution and Health in 2000, 2005, 2010, 2014, and 2019. The height, weight, and BMI of 548 419, 548 408, and 548 365 urban students aged 7–18 years, respectively, were tested. The mean differences across survey years were tested by one-way analysis of variance (ANOVA). The pace of secular trends is expressed as the change every 5 years between every two adjacent survey years.
Results
Height increments between 1.9 and 6.2 cm, weight increments between 2.7 and 8.6 kg, and BMI increments between 0.9 and 1.9 kg/m2 were observed in boys. For girls, height increments between 1.5 and 4.9 cm, weight increments between 2.2 and 6.0 kg, and BMI increments between 0.7 and 1.7 kg/m2 were observed. The pace of secular trends in height decreased in the last 5 years, and the secular trends in weight and BMI have accelerated in the last 9 years compared with the previous 10 years.
Conclusions
Although the secular trend in height among Chinese urban students has slowed, it has not yet reached its genetic potential and continues to increase. The rapid increase in weight and BMI was a cause for concern. Our findings provide a basis for the future formulation of public health interventions in China.
期刊介绍：
The American Journal of Human Biology is the Official Journal of the Human Biology Association.
The American Journal of Human Biology is a bimonthly, peer-reviewed, internationally circulated journal that publishes reports of original research, theoretical articles and timely reviews, and brief communications in the interdisciplinary field of human biology. As the official journal of the Human Biology Association, the Journal also publishes abstracts of research presented at its annual scientific meeting and book reviews relevant to the field.
The Journal seeks scholarly manuscripts that address all aspects of human biology, health, and disease, particularly those that stress comparative, developmental, ecological, or evolutionary perspectives. The transdisciplinary areas covered in the Journal include, but are not limited to, epidemiology, genetic variation, population biology and demography, physiology, anatomy, nutrition, growth and aging, physical performance, physical activity and fitness, ecology, and evolution, along with their interactions. The Journal publishes basic, applied, and methodologically oriented research from all areas, including measurement, analytical techniques and strategies, and computer applications in human biology.
Like many other biologically oriented disciplines, the field of human biology has undergone considerable growth and diversification in recent years, and the expansion of the aims and scope of the Journal is a reflection of this growth and membership diversification.
The Journal is committed to prompt review, and priority publication is given to manuscripts with novel or timely findings, and to manuscripts of unusual interest.
