Changes in the consumption of foods characterising the Mediterranean dietary pattern and major correlates during the COVID-19 confinement in Italy: results from two cohort studies.

We investigated the effect of confinement during the COVID-19 pandemic on the consumption of foods characterising the Mediterranean dietary pattern (MDP) and its major correlates in two Italian population-based cohorts comprising 3161 subjects (mean age 57.7 ± 15.4 y). At population level, 38.8% of participants reported an improvement of diet quality during the first nationwide lockdown. Healthful dietary changes were associated with older age ( = 0.41; 95% confidence interval [CI] 0.08, 0.73 for 56-65 18-39 y), greater wealth ( = 0.45; 0.01, 0.89 for >40,000 ≤ 60,000 ≤ 10,000 EUR/y), increased physical activity ( = 0.52; 0.22, 0.81) and reduced body weight ( = 0.36; 0.11, 0.62). Switching to healthy eating was also related to increased consumption of organic ( = 1.24; 0.88, 1.60) and locally-grown food ( = 0.74; 0.51, 0.96). The first Italian lockdown led, in a substantial part of the population, to higher intake of foods characterising a MDP; this was also accompanied by healthier lifestyle and more sustainable food choices.
