Abstract

Background: Children and adolescents are increasingly exposed to processed food in China, however, its association with obesity has not been investigated.

Objectives: To assess the consumption of ultra-processed food (UPF) and its association with overweight/obesity among children and adolescents in China.

Methods: A total of 3437 children and adolescents aged 6-18 years, participating at least twice in the China Nutrition and Health Survey, were included. Food intake was collected using a 3-day 24-h dietary recall method at home visits. Body weight, height and waist circumference (WC) were measured during the survey. UPF was defined by food process levels using NOVA classification. Overweight/obesity was defined by the international age- and sex-specific BMI and WC cut-offs. The association between UPF consumption and overweight/obesity was assessed using mixed effect logistic regression analyses adjusted for socio-demographic, economic, behavioural, dietary and health factors.

Results: The mean daily UPF consumption of the study population (mean age 9.3 years) increased from 9.7 in 1997 to 60.0 grams in 2011. The adjusted odds ratios (OR) (95% CI) for overweight/obesity (using BMI) for UPF consumption of 0, 1-49, 50-99 and ≥ 100 g/day were 1.00, 1.38 (0.98-1.94), 2.01 (1.25-3.24) and 1.53 (0.82-2.86), respectively (p-trend =0.013). Similarly, the corresponding adjusted ORs (95% CI) for central obesity (using WC) were 1.00, 1.84 (1.30-2.60), 2.13 (1.30-3.48) and 2.15 (1.14-4.05) (p-trend<0.001).

Conclusions: Higher long-term UPF consumption was associated with an increased risk of overweight/obesity among children and adolescents in China.

期刊介绍： Pediatric Obesity is a peer-reviewed, monthly journal devoted to research into obesity during childhood and adolescence. The topic is currently at the centre of intense interest in the scientific community, and is of increasing concern to health policy-makers and the public at large. Pediatric Obesity has established itself as the leading journal for high quality papers in this field, including, but not limited to, the following: Genetic, molecular, biochemical and physiological aspects of obesity – basic, applied and clinical studies relating to mechanisms of the development of obesity throughout the life course and the consequent effects of obesity on health outcomes Metabolic consequences of child and adolescent obesity Epidemiological and population-based studies of child and adolescent overweight and obesity Measurement and diagnostic issues in assessing child and adolescent adiposity, physical activity and nutrition Clinical management of children and adolescents with obesity including studies of treatment and prevention Co-morbidities linked to child and adolescent obesity – mechanisms, assessment, and treatment Life-cycle factors eg familial, intrauterine and developmental aspects of child and adolescent obesity Nutrition security and the "double burden" of obesity and malnutrition Health promotion strategies around the issues of obesity, nutrition and physical activity in children and adolescents Community and public health measures to prevent overweight and obesity in children and adolescents.
