INTRODUCTION: Overweight and obesity are serious health problems in Portugal,
with physical, psychological and social consequences that affects individuals’
quality of life.
In university students’ daily routine, sitting is a predominant behavior for many
hours per day, increasing sedentary time among these individuals.
OBJECTIVES: The purpose of this study was to analyze the association between
the time spent sitting in an ordinary weekday and body mass index in a sample
of Portuguese university students.
METHODOLOGY: This was a cross-sectional study performed in 72 Portuguese
university students (38 female; 22.1 ± 3.9 years of age). The time spent sitting
in an ordinary weekday was assessed with the International Physical Activity
Questionnaire (short last week version). Body mass index was calculated through
self-reported body weight (kg) and body height (m) data with the formula body
weight (kg) / body height (m)2.
RESULTS: The time spent sitting in an ordinary weekday was 342.1 ± 192.7
minutes. The mean value of body mass index was 22.9 ± 2.9 kg/m2. Through
the use of Pearson correlation, we determine that the association between sitting
time and body mass index is positive and significant (r = 0.511; p < 0.001).
CONCLUSIONS: Our study revealed that there was significant association between
sitting time and body mass index in this sample of Portuguese university students.
Although the cross sectional design of our study do not allow to establish
causality, it suggests the need of effective strategies to reduce time sitting in
this individuals.
