Abstract Objective To comprehensively evaluate the physical shape, nutritional status, cardiopulmonary function, and visual health of school-aged children, and provide scientific basis for the prevention and control of childhood obesity, hypertension, and reduced visual acuity. Methods A total of 4 484 children aged from 7 to 12 years were involved by a cluster sampling method in Weifang, Shandong province. Their height, weight, chest circumference, vital capacity, blood pressure, and vision were measured. Levels of physical indicators of the children were compared with average levels of national-wide children. And the relationship between body mass index (BMI) and cardiopulmonary function was analyzed. Results Average levels of growth and development indicators of the children were higher than those of the national-wide children. The prevalence of growth retardation (0.4%) and wasting (8.0%) was lower. However, the prevalence rates of obesity, hypertension, and reduced visual acuity were 15.6%, 18.5%, and 55.8%, respectively, which were higher than those of national-wide children. The prevalence of obesity of boys (19.2%) was higher than that of girls (12.0%), while the prevalence of reduced visual acuity displayed a reverse fashion, which was 62.0% for girls and 52.2% for boys. BMI was positively correlated with vital capacity and blood pressure. Conclusion High prevalence of obesity, hypertension, and reduced visual acuity was found among the children in Weifang, Shandong. The increased blood pressure may at least partially be owing to the obesity. It is urgent to prevent and control the childhood obesity, hypertension, and reduced visual acuity.
