A longitudinal study, from 2018 to 2021, identified impacts on the nutritional and functional status of older adults when face-to-face activities at a social assistance center in Mexico were suspended due to the COVID-19 pandemic. A total of 71 older adults were evaluated at three different periods: 18 months prior, three months before the pandemic, and 12 months after the onset of the pandemic. Seventy-one older adults completed follow up. Anthropometric measurements, dietary intake, physical tests, and health screening for malnutrition, dependence, and physical frailty, were evaluated. There was a significant decrease in lean body mass and body water in the older adults assessed, in addition to a significant reduction in the frailty scale and gait speed. Finally, a significant reduction in ingested energy and several nutrients such as protein, and carbohydrates, was found, yet an increase in sugar and cholesterol intake was noted.
