Changes in BMI and waist circumference among primary and secondary school students from 2005 to 2010 in Anhui, China.

Aim: To examine the change in Body Mass Index (BMI) and waist circumference (WC) among primary and secondary school students aged 7-18 in Anhui Province between 2005-2010.

Subjects And Methods: A total of 15 812 primary and secondary school students aged 7-18 were included in two national surveys on students' constitution and health in 2005 and 2010 in Anhui Province. Measurements of height, weight and WC were taken by trained investigators.

[Association between body mass index and physical fitness index among children and adolescents].

Objective: To explore the relationship between body mass index (BMI) and physical fitness index (PFI) among children and adolescents.

Methods: The study sample included 8941 students aged 7 to 18 years in Anhui who attended the Physical Fitness and Health Surveillance program of Chinese School Students, in 2010. Within each sex- and age-specific group, students were classified into five BMI categories which were: very low, BMI<5th percentile; low, BMI≥5th but <15th percentiles; normal, BMI≥15th but <85th percentiles; high, BMI≥85th but <95th percentiles; and very high, BMI≥95th percentiles.

[Psychopathological sub-healthy status as predictor on self-or unintentional injuries among Chinese adolescents: a school-based follow-up study].

Objective: To investigate the association between psychological sub-healthy status and risks on injuries and related predictors among adolescents in China, in order to develop reasonable intervention programs.

Methods: Adolescents were selected from middle schools and colleges in eight cities. Baseline status on sub-healthy that related to psycho-pathology was measured using the Multidimensional Sub-health Questionnaire of Adolescents (MSQA).

[Relationship between waist circumference development curve of children and hypertension and risk of hypertension].

Objective: The 85th percentile of waist circumference (WC) is considered an appropriate cutoff for Chinese children in the prediction of cardiovascular risks in previous researches, but the risk for hypertension of moderate WC maybe underestimated. The purpose of this study was to understand the characteristics of the WC curve trajectory of children with hypertension and to determine the appropriate cutoffs for waist circumference for Chinese school-age children and adolescents for predicting hypertension risk factors.

Methods: A total of 8194 Han children aged 7 - 17 years were selected from schools in Suzhou, Hefei, and Chizhou cities in Anhui province by stratified cluster sampling.

[Association between self-assessed somatotypes and symptom depression among children and adolescents].

Association between self-assessed somatotypes, body mass index (BMI) and depression symptom were examined.

Plasma L-ENK, AVP, ANP and serum gastrin in patients with syndrome of Liver-Qi-stagnation.

AIM:To investigate the pathophysiologic basis of syndrome of Liver-Qi stagnation and parameters for clinical differentiation.METHODS:Plasma L-ENK, AVP, ANP and serum gastrin were determined by RIA in 84 patients with neurasthenia, mastodynia,chronic gastritis, and chronic cholecystitis presenting the same syndrome of Liver-Qi stagnation in traditional Chinese medicine (TCM). Healthy subjects served as controls in comparison with patients having the same syndrome but with different diseases.
