Corporal body adiposity (BAI) and abdominal volume (AVI) indices. Relationship with lifestyle in the working population

Introduction: Obesity is a global problem of increasing prevalence. The pathogenesis of cardiovascular disease begins long before the onset of a cardiovascular event. The aim of this work is to assess obesity-related adiposity with abdominal volume index (AVI) and body adiposity index (BAI), sex differences and their relationship with obesity parameters and socio-cultural variables. Methods: Cross-sectional study in Spanish workers from different sectors from January 2019 to September 2021. AVI and BAI values were calculated using their specific formulas and their relationship with body mass index (BMI), waist circumference (WC), waist height index (WHI) and waist hip index (WHI). The relationship of both indexes with healthy lifestyle was studied: diet-PREDIMED and physical activity-IPAC-reduced. The SPSS 27.0 program was used, considering statistical significance p<0.05. Results: Study conducted on 193,462 workers (116,407 men and 77,055 women) with mean age 39.2 years for women and 39.8 years for men; overweight body mass index: 25.2 for women, 26.8 for men; greater physical activity (54.5%) and healthy eating (59.1%) in women. The mean values of AVI and BAI increase in both sexes with age, especially after 50 years of age, in women with primary education and social class III and in men with primary/secondary education and social class III. In both sexes they are higher when there is no physical activity or no adherence to the Mediterranean diet. In both sexes they are higher in non-smokers (p<0.0001) and are higher in both sexes when ICA, ICC are high and BMI is obese. The mean values of AVI are higher in men and those of BAI in women (p<0.0001). Conclusions: Body adiposity indexes (BAI) and abdominal volume index (AVI) show differences between men and women, increase their mean values with age, show relationship with social and cultural situation and with healthy life habits. The mean values of AVI and BAI increase as do the parameters of obesity in both sexes: ICA, ICC and BMI.
