Introduction and purpose: Lifestyle is one of the most important factors affecting the quality of life, including cardiovascular diseases. Regarding this,
the aim of this study was to investigate the association of abdominal obesity with demographic factors and cardiovascular fitness in Babolsar, Iran. Methods: This study was conducted on 150 women and men residing in Babolsar. The study population was selected using simple random sampling technique through a recall. The data were collected using demographic form, pedometer (to evaluate the physical activity level), body mass index (BMI; to assess abdominal obesity), waste hip ratio (WHR), and body adiposity index (BAI). The data were analyzed using Chi-square test, Pearson correlation, and ANOVA. P-value less than 0.05 was considered statistically significant. Results: According to the results, peak oxygen uptake was indirectly associated with BMI, WHR, and BAI in both genders (P<0.001). On the other hand, there was a direct relationship between these variables and age (P<0.001). Furthermore, a direct correlation was observed between WHR and the marital status of the women (P=0.008). Additionally, BMI levels had a nonsignificant increase with the enhancement of age and decline of education level. Conclusion: The promotion of peoples’ awareness about abdominal obesity and its associated factors and their encouragement to perform physical activity can be effective in reducing the prevalence of abdominal obesity and its comorbidities.
