Background: The SARSCOV-2 pandemic has led to a dramatic increase in the levels of sedentary lifestyles and unhealthy dietary habits. A worsening in populational obesity levels and body composition (BC) is strongly awaited but has not yet been documented.
Objective: To compare the BC profile measured by bioelectrical impedance analysis (BIA) between prepandemic (P1-03/15/2017 to 03/16/2020) and pandemic (P2-3/17/2020 to 3/10/2021) periods.
Materials and Methods: BIA was grouped according to the time it was performed. Two comparisons were made: an independent sample comparison (ISC) and a paired sample comparison (PSC), considering patients with at least one BIA in P1 and P2. Age, height, sex, weight, body mass index (BMI), body fat mass (BFM), free fat mass (FFM), skeletal muscle mass (SMM), percentage of body fat (PBF), and visceral fat area (VFA) were compared. The statistical significance level was defined for a p value < 0.05.
Results and Discussion: 3.358 BIA was performed, and 2.771 and 112 were selected for IS and PS, respectively. In ISC, despite an unchanged weight, BFM, FFM, PBF, and VFA increased, and SSM decreased on P2 (p < 0.015 for all). Using PBF as a dependent variable, a multivariate linear regression model showed P2 as an independent predictor (β = 0.38 95% CI 0.19 to 0.56). In the PSC, PBF also increased from P1 to P2 (p = 0.015). To our knowledge, this is the first documentation of worsening BC after the pandemic. Health authorities should be alert to this phenomenon and its clinical consequences in the future.
