Correlations between Excessive Body Mass Index, Body Perception, Physical Activity, and Respiratory Functions among Youths in an Urban Setting of Vietnam

Abstract EN

Young adults are susceptible to overweight and obesity and their adverse outcomes.

However, limited studies have been conducted to understand this health problem in Vietnamese youths.

This study was conducted to examine the rate of overweight and obesity, as well as the relationship between this condition on body perception, physical activity, and respiratory function among young adults in Hanoi, Vietnam.

We performed a cross-sectional survey with 367 students aged 18-25 years at the Hanoi University of Pharmacy from June 2017 to June 2018.

The result showed that the rate of overweight and obesity in our sample was 16.6%.

There were 55.7% of overweight/obese students having the misperception of their body image.

Results of multivariate regression analysis showed that overweight/obesity increased nearly three times (OR=2.8, 95% CI: 1.5-5.0) the ability to be active.

Overweight/obese students with physical activity had a better respiratory function.

To conclude, this study underlined the associations between overweight and obesity with physical activity, body image, and respiratory function in our young sample.

Further longitudinal studies should be warranted to examine their causal relationships.
