本研究的目的在探討影響國小學童身體質量指數（BMI）、體型意識及運動自信因素之關係。以屏東市某國小六年級學童214人為研究對象（男＝110；女＝104；平均年齡＝11.32（.52），施以「飲食態度問卷」、「體適能態度量表」、「運動自信量表」及「體型意識量表」。經採路徑分析檢驗假設因果模式，結果發現：一、學童的性別、父母體型及運動頻率對其BMI影響達顯著水準，五自變數對其BMI的解釋量為20.70﹪；二、學童的性別、飲食態度及BMI對其體型意識之影響達顯著水準，六自變數對體型意識的解釋量為33.51﹪，上述外因變項分別透過學童的BMI對其體型意識產生間接效果；三、學童的性別、體適能態度、運動頻率及BMI對其運動自信之影響達顯著水準，六自變數對國小學童運動自信的解釋量為19.51﹪，上述外因變項分別透過學童之BMI對其運動自信產生間接效果。從上述路徑分析結果，顯示本研究之假設因果模式大致成立，唯自變數對依變數的解釋量均在20－33.5﹪間，顯示尚有其他變數影響學童之BMI、體型意識及運動自信。根據本研究結果，對國小健康教育、體育教學及未來的研究提出一些建議。The purpose of this study was to examine cause-effect relationship among body mass index(BMI), body image(BI) and sport self-confidence(SSC) in elementary school children. A total of 214 elementary school children (males=110; females=104; age=11.32(.52) were administered with eating-attitudes(EA) scale, fitness-attitude(FA) scale, SSC scale and BI scale. The data were analysized by path analysis to examine the cause-effect model. The results were as followed: (1) Except EA and FA that gender, parents body buildup (PBB) and exercise frequency (EF) all had significant influenced on BMI. The BMI explained by five independent variables were 20.70%. (2) As to the influence of gender, EA, PBB, FA, EF and BMI on BI. Only gender, EA and BMI demonstrate significant results. The BI explained by six independent variables was 33.51%. In addition, exogenous variable had indirect influenced on BI through BMI. (3) As to the influence of gender, EA, PBB, FA, EF and BMI on SSC. Only gender, FA and EF and BMI had significant results. The SSC explained by six independent variables were 19.51%, further, exogenous variable had indirect influenced on SSC through BMI. According to the result of path analysis, the hypothesized model was to establish. Because the coefficient of determination(R2) were only 20-33.5﹪, it indicated that there had another factor influence the BMI, BI and SSC. In addition, this study also provided suggestions to health education, physical education and future researches. |
