| 1 | Validation of the Physical Activity Questionnaire for Older Children(PAQ-C) among Chinese Children显示文摘Objective This study initially validates the Chinese version of the Physical Activity Questionnaire for Older Children(PAQ-C), which has been identified as a potentially valid instrument to assess moderate-to-vigorous physical activity(MVPA) in children among diverse racial groups. Methods The psychometric properties of the PAQ-C with 742 Hong Kong Chinese children were assessed with the scale's internal consistency, reliability, test-retest reliability, confirmatory factory analysis(CFA) in the overall sample, and multistep invariance tests across gender groups as well as convergent validity with body mass index(BMI), and an accelerometry-based MVPA. Results The Cronbach alpha coefficient(α=0.79), composite reliability value(ρ=0.81), and the intraclass correlation coefficient(α=0.82) indicate the satisfactory reliability of the PAQ-C score. The CFA indicated data fit a single factor model, suggesting that the PAQ-C measures only one construct, on MVPA over the previous 7 days. The multiple-group CFAs suggested that the factor loadings and variances and covariances of the PAQ-C measurement model were invariant across gender groups. The PAQ-C score was related to accelerometry-based MVPA(r=0.33) and inversely related to BMI(r=-0.18). Conclusion This study demonstrates the reliability and validity of the PAQ-C in Chinese children. | WANG Jing Jing BARANOWSKI Tom LAU WC Patrick CHEN Tzu An PITKETHLY Amanda Jane | 2016 | Biomedical and Environmental Sciences2016，29，3： | 7 |

| 13 | An Objective Measure to Evaluate Actual Body Shape among Children and Adolescents in China显示文摘Objective The purpose of this study was to explore an objective measure to assess actual body shape of children and adolescents in China.Methods Based on the Chinese National Survey on Student’s Constitution and Health(CNSSCH)in2005,210 927 children and adolescents'(7-18 years)body height,body weight,chest circumference,sitting height,chest circumference-height ratio,chest circumference-sitting height ratio,chest circumference-low limb ratio,and sitting height-low limb ratio measurements were used to develop an objective measure by using transformation variables and explored factor analysis(EFA).Discrimination power of the objective measure was evaluated based on BMI reference and Receiver Operating Characteristic curves(ROC).Results The objective measure included four dimensions scores:transverse dimension(TD)indicating weight and chest circumference;length dimension(LD)indicating height and sitting height;transverse-length ratio dimension(TLD)indicating chest circumference-height ratio,chest circumference-sitting height and chest circumference-low limb ratio;proportion dimension(PD)indicating sitting height-low limb ratio.The whole dimension(WD)indicating the whole body shape was showed by the average of four dimensions scores.Four dimensions and WD scores were approximately80 in children and adolescents with normal weight,and higher than those of overweight,obesity,and underweight(all P-values<0.001).Areas under ROC of overweight and obesity compared with normal weight ranged from 0.88 to 1.00 for scores of TD,TLD,and WD.Conclusion The objective measure which included four dimensions was explored,and TD,TLD,and WD had significant discrimination power. | FU Lian Guo WANG Hai Jun LI Xiao Hui WANG Zhi Qiang Patrick WC Lau YANG Yi De MENG Xiang Kun MA Jun | 2014 | Biomedical and Environmental Sciences2014，27，8： | 0 |
