Abstract

Background. This study aimed to assess secular trends and epidemiological status of ascariasis infestations and to explore its effects on the nutritional transition among Chinese children from 2000 to 2014. Methods. Data were collected from 69 435 Chinese children aged 7-year-olds and 9-year-olds in 4 successive cross-sectional surveys of Chinese National Survey on Students’ Constitution and Health. Ascariasis infestation was defined by using the Kato-Katz method. Nutritional status was classified into stunting, thinness, overweight, and obesity by WHO definition. Results. From 2000 to 2014, the ascariasis infestation rates decreased from 9.1% to 1.7%, the stunting and thinness prevalence decreased from 4.3% and 13.8% to 0.7% and 7.1%, while the overweight and obesity prevalence increased from 3.6% and 2.1% to 9.8% and 9.1%, respectively. Compared to children in the ascariasis noninfestation group, those infected with ascariasis had a worse nutritional status. Yet, the disparity in nutritional status between 2 groups disappeared over time. Provinces with a higher gross domestic product per capita simultaneously had lower ascariasis infestation rates, lower stunting and thinness prevalence, and higher overweight and obesity prevalence. Conclusions. The retardation effects caused by ascariasis infestation on nutritional status in Chinese children seemed to be offset by the rapid economic development and nutritional transition over time; nevertheless, multiple prevention and control measures are still needed and should be continuously strengthened.
