為瞭解學生與父母體型之相關情形，以臺北市立國民中學八十學年度全體新生共47,173人為母群體，採系統集束抽樣，選出1174名樣本為調查對象。學生除集體填答問卷，並接受身高、體重及皮脂厚度測量外，另攜問卷回家由父母親自填答有關自己及家庭的資料。結果發現學生的父親和母親體型過重者分別佔20.6％和16.5％；已達肥胖標準者分別為5.9％和3.5％。學生和父母體型的相關值為：身高介於0.21-0.34之間；體重介於0.22-0.34之間；體質指數介於0.21-.036之間。學生以三頭肌及肩胛肌兩皮脂厚度之平均值為體型指標之分佈來看，當父母二人體型都過重或肥胖時，學生的兩皮脂厚度平均值等於20.0或以上之比率佔43.5％；落在平均值加上一個標準差的比率為37.5％。除父母體質指數外，學生的活動消耗熱量及高熱量食物攝取頻率，也影響學生體型是否肥胖的相關因素，但後兩因素與肥胖程度出現相反的關係。本研究結果可作為發展青少年體重控制計劃的參考。

　　　　　In order to understand the resemblancesof obesity in adolescent and their parents, a cross-sectional survey wasconducted in 1991. A systematic sampling procedure by cluster was employed, 1174subjects were selected from Taipei City Junior High Schools which included47, 173 seventh graders. The subjects were asked to complete a set ofquestionaire. A measurement of height, weight and skinfold thickness were asloadministered. Then students brought another questionaire home and asked theirparents to complete their personal and family information. The prevalence ratesof overweight were 20.6% for fathers and 16.5% for mothers. The prevalence ratesof obesity were 5.9% of fathers and 3.5% of mothers. The correlationcoefficients was 0.21 to 0.34 of height, 0.22 to 0.34 of weight and 0.21 to 0.36of body mass index between the parents and students. The mean of tricep andsubscapular skinfold thickness was adopted as criterial. There were 43.5%students whose mean of the two skinfolds' thickness above 20 and 37.5% studnetswhose mean of teh two skinfolds above mean plus one standard derviation for tthestudents whose parents were overweight or obese. Not only parents' fatness, butalso frequency of high caloric foods intake or energy comsuming exercises weremajor related factors, but the latter two factors were in negative association.The results from this study can be used in designing adolescent weight controlintervention program.
