Percentiles of waist-hip ratio and the relationship with blood pressure among children and adolescents in Shandong, China.

Background: Anthropometric indices such as waist circumference (WC), waist-to-height ratio (WHtR) and waist-hip ratio (WHR) have been recognized as useful alternatives to visceral fat measurement in epidemiological studies. WHR has been used extensively in adults. However, there are very few published data for WHR among children and adolescents.

[Status quo and characteristics of blood pressure among children and adolescents aged 7-17 years at normal weight but with abdominal obesity, in Shandong province].

Objective: To study the prevalence and characteristics of blood pressure (BP) among children and adolescents at normal weight but with abdominal obesity.

Methods: Using data from the 'Student physical fitness and health surveillance 2010 project' in Shandong province, a total of 38 816 students aged 7-17 years were selected to participate in this study. Stature, body weight, waist circumference(WC), systolic blood pressure(SBP)and diastolic blood pressure(DBP) of these subjects were measured.

Blood pressure among children and adolescents with normal weight but large waist circumference in Shandong, China.

Unlabelled: The present study examined the blood pressure (BP) characteristics of normal weight children and adolescents with a large waist circumference (WC) in a large population in Shandong, China. A total of 38,826 students (19,460 boys and 19,366 girls) aged 7-17 years participated in this study. Height, weight, WC, and BP of all subjects were measured.

[Study on waist circumference and hip circumference of 7 - 18 year-old children and adolescents in Shandong province].

Objective: To study the development of waist circumference (WC) and hip circumference (HC) in children and adolescents in Shandong province, and to provide scientific data for developing related reference values for screening central obesity in Chinese children and adolescents.

Methods: Using data from 'Student physical fitness and health surveillance 2010 project' in Shandong province, a total of 42 275 students aged 7 - 18 years were selected to participate in this study. WC, HC, waist-to-hip ratio (WHR) and wrist-to-stature ratio (WSR) of subjects were measured.

Comparison on physical activity among adolescents with different weight status in Shandong, China.

The present study examined the prevalence of underweight, overweight and obesity among adolescents and compared the attitudes and behaviors of physical activity (PA) among adolescents with different weight status in Shandong, China. A total of 19 523 students (9784 boys and 9739 girls) aged 13-18 years participated in this study. Height and weight of all subjects were measured, body mass index of adolescents was calculated from their height and weight, and the prevalence of overweight and obesity were obtained according to the International Obesity Task Force cut-offs.

The role of 1-h physical activity every day in preventing obesity in adolescents in Shandong, China.

Several studies have reported that physical inactivity and sedentary lifestyle are associated with being overweight and obese in children and adults. A new policy of 1-h physical activity (PA) every day was released by the Chinese government. The present study examined the role of 1-h PA every day in preventing obesity in adolescents in Shandong, China.

Distributions of waist circumference and waist-to-height ratio for children and adolescents in Shandong, China.

Unlabelled: Waist circumference (WC) and waist-to-height ratio (WHtR) are useful tools which can help to identify abdominal obesity among the childhood and adolescent populations. This study assessed the distributions of WC and WHtR for Shandong children and adolescents and compared them with those from other countries and regions. Data for this study were obtained from a large cross-sectional survey of schoolchildren carried out in 2010.
