Abstract
Improving daily-life habits is considered to be effective in treating obesity. We have examined obesity in regular physical examinations in university students since 1974. In this study, the subjects were 199 s tudents regarded as obese (Broca's index: more than 120%) and 326 non- obese students randomly selected (525 subjects in total) among student s who underwent regular physical examinations at Nagoya University, Ja pan, between 1974 and 1978, Here we report our follow-up survey of obe se university students and non-obese individuals who were students of the same university during the same period. This study was carried out for the purpose of clarifying the relationship between changes in lif estyle and body weight 20 years after graduation. Concerning eating: b ehavior, a higher proportion of subjects cared about diet intake in th e current non-obese group than in the current obese group (P < 0.05). The meal-time in the obese was shorter than that in the non-obese grou p (P < 0.01). Ten percent of subjects in the obese group and 24.4% of subjects in the non-obese group selected class II (moderate) or higher as indicative of the intensity of their daily physical activity. Ther e was a significant difference in distribution between the groups (P < 0.05). In the group showing improvement in obesity over time, a highe r proportion of subjects cared about diet intake than in the group wit h continued obesity (P < 0.05), Concerning intensity of physical activ ity, 11.8% of subjects in the group with continued obesity selected cl ass II (moderate) or higher, while 45.5% of subjects in the group show ing improvement in obesity chose class II(moderate) or higher. A signi ficant difference in distribution existed between the groups (P < 0.01 ). These findings suggest that the eating behavior of ending meals bef ore feeling satiety and a lifestyle change to enhance the intensity of daily physical activity including walking, even if not having any spe cial sports habits, are effective in decreasing body weight.
