- W2806838650 abstract "PURPOSE: This study evaluated whether young children perceive their body weight correctly, and to investigate relationships among weight perception, exercise behavior and physical fitness in elementary school children. METHODS: We recruited 200 boys (9±1 yrs, 138±6 cm, 37±10 kg, 19±4 kg/m2) and 197 girls (9±1 yrs, 138±6 cm, 36±9 kg, 19±3 kg/m2). Their physical fitness such as endurance shuttle run (63±26 vs. 51±20 laps), sit-and-reach (5.8±6.5 vs. 8.8±5.6 cm), grip strength (15±3 vs. 14±3 kg), and standing long jump (137±21 vs. 123±21 cm for boys vs. girls) were measured. They responded to a questionnaire reporting weight perception, exercise participation, physical activity time, physical activity preference. Their relative weight status (BMI percentile) was categorized as; underweight (<5%, UW), normal weight (5-85%, NW), and overweight/obese (85%<, OW). Data analyses were performed using Chi-square test, Fisher’s exact test, Independent t-test and One-way ANOVA. RESULTS: More than one third (36.8%) of children misperceived their body weight compared with the actual weight. In particular, body weight misperception rate was higher in NW than UW and OW. Girls considered themselves more to be overweight while boys did more to be underweight. Physical activity time and physical activity preference were not related to weight perception. Exercise participation showed differences according to gender. Physical fitness level was related to exercise behaviors. Physical fitness was higher for children who liked to exercise or were being active than those who were not. Endurance run and standing long jump were more strongly associated with physical activity preference than physical activity time, and a dose-response relationship was observed. CONCLUSIONS: Overall, weight perception of the children was not quite accurate when compared with their actual body weight. However, there was no difference in exercise behaviors according to weight perception. Physical fitness level was associated with exercise behaviors. Endurance run and standing long jump were more strongly associated with physical activity preference than physical activity time (NRF-2013M3C8A2A02078508)." @default.
