Body Fat and Visceral Fat Values in Spanish Healthcare Workers: Associated Variables

Background/Objectives: Excessive body adiposity is a significant public health challenge on a global scale. This study aimed to investigate the association between various sociodemographic factors and healthy lifestyle habits and the presence or absence of elevated body adiposity levels. Methodology: Two studies were conducted, a retrospective longitudinal study and a cross-sectional descriptive study. The analysis included 44,939 healthcare workers, categorised into four professional groups, to explore the relationship between age, sex, smoking, physical activity, and adherence to the Mediterranean diet and body adiposity, assessed as elevated body fat (BF) and visceral fat (VF) levels. Descriptive statistics encompassed categorical and quantitative variables, analysed using frequencies, Student&rsquo:s t-tests, chi-square tests, and multinomial logistic regression models. Associations, concordances, and correlations were further examined using logistic regression and Cohen&rsquo:s and Pearson&rsquo:s kappa coefficients. Results: Age, sex, and physical activity were the factors most strongly associated with elevated BF and VF levels. Odds ratios (ORs) indicated the following significant associations: individuals aged 60 years and older exhibited ORs of 6.71 (95% CI: 5.68&ndash:7.74) for BF and 12.18 (95% CI: 10.01&ndash:14.26) for VF: male sex was associated with ORs of 2.21 (95% CI: 2.06&ndash:2.36) for BF and 12.51 (95% CI: 11.29&ndash:13.74) for VF. Sedentary behaviour was linked to ORs of 3.69 (95% CI: 3.41&ndash:3.97) for BF and 4.20 (95% CI: 3.78&ndash:4.63) for VF. Among healthcare professionals, nursing assistants and orderlies demonstrated the highest levels of adipose tissue accumulation. Conclusions: Elevated BF and VF levels among healthcare personnel are significantly associated by lifestyle factors, sex, and age, with the most pronounced risk observed in nursing assistants and orderlies. Further research focusing on the causal relationships between lifestyle behaviours and adiposity in this population will provide valuable insights and support the design of targeted preventive strategies to mitigate its prevalence.
