Body Mass Weight Study
Body Mass Study Aim
To discover if body mass change and habitual leisure time physical activity
of working-aged men and women are associated.
Body Mass Study Design
Prospective 10-year follow-up study.
Body Mass Study Subjects
A regionally representative cohort of 19-63 year old men and women in
three municipalities in Finland.
Body Mass Study Measurements
The main outcome measures were average body mass change during the 10
years of follow-up and the clinically significant body mass gain defined
as a body mass gain of 5 kg or more during the follow-up and a body mass
index of 26 or higher at the end of the follow-up. Leisure time physical
activity was determined from self-administered questionnaires.
Body Mass Study Results
After adjustment for the potential confounders, the logistic regression
analysis showed that the men and women with no regular weekly activity
at the end of the follow-up had an odds ratio of 2.59 and 2.67, respectively
for clinically significant body mass gain in comparison with the most
active groups. The men who had decreased their activity during the 10
y follow-up had an odds ratio of 1.96, and the men who were physically
inactive all the time had an odds ratio of 1.62 for clinically significant
body mass gain when compared with the subjects who were active all the
time. Among the women the odds ratios for clinically significant body
mass gain after adjustment for potential confounders were 2.49 and 1.61,
respectively.
Body Mass Study Conclusion
These findings are consistent with the hypothesis that regular physical
activity prevents body mass gain and physical inactivity is a risk factor
for body mass gain and obesity among adults.
