The relationship between quality of life, physical activity and body satisfaction among adolescents

Cilj istraživanja bio je istražiti odnos kvalitete života povezane sa zdravljem, fizičke aktivnosti i zadovoljstva vlastitim tijelom kod adolescenata. Pri tome se također željelo utvrditi postoje li spolne razlike u bavljenju fizičkom aktivnošću i u zadovoljstvu vlastitim tijelom. Istraživanje je provedeno na uzorku od 120 učenika prvih i drugih razreda srednje škole gimnazije i strukovnim škola. U istraživanju su korišteni sljedeći instrumenti: Upitnik KIDSCREEN-52, adolescenti (Ravens-Sieberer i sur., 2005) za mjerenje kvalitete života povezane sa zdravljem, Skala zadovoljstva tijelom (Pingitore, Spring i Garfield, 1997) za mjerenje zadovoljstva vlastitim tijelom i Upitnik fizičke aktivnosti za adolescente (Kowalski, Crocker i Donen, 2004) za mjerenje razine fizičke aktivnosti. Rezultati su pokazali da postoji pozitivna i statistički značajnamala do umjerena korelacija između kvalitete života povezane sa zdravljem i fizičke aktivnosti i zadovoljstva vlastitim tijelom. Nadalje, u obzir je uzeta i dodatna varijabla indeksa tjelesne mase (ITM) koja je s ostalim varijablama ostvarila negativnu povezanost, od čega je statistički značajna bila samo ona s tjelesnom dobrobiti kao dijelom kvalitete života povezane sa zdravljem. Utvrđene su i spolne razlike u bavljenju fizičkom aktivnošću i zadovoljstvu vlastitim tijelom i to u smislu većeg angažmana mladića u bavljenju fizičkom aktivnošću i većeg nezadovoljstva vlastitim tijelom kod djevojaka.The aim of the study was to examine a relationship between health-related quality of life, physical activity and body satisfaction among adolescents. The second purpose of the study was to determine gender differences to engaging in physical activity and body satisfaction. Research was conducted on 120 students of the first and second class of high school and vocational school. The instruments which were used include KIDSCREEN-52 questionnaire of health-related quality of life for adolescents (Ravens-Sieberer & Co., 2005); Body shape satisfaction scale – BSSS (Pingitore, Spring and Garfield, 1997) for the measurement of body satisfaction and Physical activity questionnaire – PAQ (Kowalski, Crocker & Donen, 2004) in order to measuring physical activity. Results have shown small to medium positive and statistically significant correlation between health-related quality of life, physical activity and body satisfaction. Furthermore, there was an additional variable which was considered during the research. It was body mass index (BMI) which has shown negative correlation with other measured variables. The only one statistically significant correlation was between body mass index and physical benefits, which was a part of the health-related quality of life's construct. Also, there were confirmed gender differences to engaging in physical activity and body satisfaction. Boys have been doing more physical activity than girls while in the other side girls have had higher body dissatisfaction
