SD: standard deviation; CI: confidence interval; BMI: body mass index; Diff: mean or percentage difference between 2018–2019 and 1998–2002 or 2018–2019 and 2008–2012. Means, standard deviations, and prevalence were age-standardized by Italian National Institute of Statistics-ISTAT Italian population 2000, 2010, and 2019, respectively.
^ t-test to compare variables between periods; chi-square test to compare prevalence between periods.
^^ Linear regression and logistic models were assessed considering indicators as dependent variable and period (2018–2019/1998–2002 or 2018–2019/2008–2012), age (35–54/55–74 years), and educational level (high/low) as independent variables; the statistical significance of the period was reported.
*** p < 0.0001
** p < 0.01
*p < 0.05; ns not significant p-value. Normal weight: 18.5 ≤ body mass index < 25.0 kg/m2. Overweight: 25.0 ≤ body mass index < 30.0 kg/m2. Obesity: body mass index ≥ 30.0 kg/m2. High waist-to-hip ratio: waist-to-hip ratio ≥ 0.90 in men and ≥ 0.85 in women. Abdominal obesity: waist circumference > 102 cm in men and > 88 cm in women.
