The BMI of participating students also showed a
significant impact on the dimensions of motivational factors
for exercise, especially when those with normal weight and
others with obesity were compared. University students with
a BMI > 30 kg/m2 had mean values of disease prevention (F
= 4.136; p = 0.002), physical appearance (F = 6.647; p < 0.001)
and health rehabilitation (F = 12.474; p < 0.001) significantly
higher than those with a BMI < 25 kg/m2. However, in the
case of stress management (F = 3.269; p = 0.023), leisure/
well-being (F = 8.906; p < 0.001) and affiliation (F = 5.123; p
< 0.001), students with normal weight (BMI < 25 kg/m2) had
statistically higher mean values than others with overweight
(25 kg/m2 > BMI > 30 kg/m2). With regard to the factor
associated with body weight management, the mean values
found rose with the increase in BMI scores, indicating
significant differences among the three strata compared (F =
85.299; p < 0.001).
