Abstract
BackgroundThe coronavirus disease (COVID-19) pandemic has resulted in reduced physical activity and social interaction. These restrictions may have affected the food intake habits of frail older people more than non-frail older people.ObjectivesTo investigate the association between frailty and change in dietary habit during the pandemic.DesignCross-sectional mail surveySettingCommunity-basedParticipantsThe study questionnaire was mailed to 4,436 older residents of Higashiura, Aich Japan, who were aged ≥75 years and who did not need care as of April 1, 2020. Of these, 2,738 participants provided complete answers to the questionnaires (75–96 years old, 49.3% males).MeasurementsThe participants’ frailty status and changes in food consumption during social isolation were assessed. Frailty status was assessed using the five-item frailty screening index (i.e., weight loss, low physical function, low physical activity, cognition, and exhaustion). Any participant who reported an increase or a decrease in ≥1 of the 12 food categories was defined as having change in dietary habit. Using multivariate logistic regression analysis, the odds ratios (ORs) and 95% confidence intervals (CIs) of frailty for changes in diet were estimated by adjusting for age, sex, BMI, and living alone. In each of the 12 food categories, the proportion of participants with increased and decreased food intake was compared between the groups.ResultsAmong the participants, 470 (17.2%) were frail, and 1,097 (40.1%) experienced a change in dietary habit under social restriction. The adjusted OR (95% CI) of the frail group for a change in dietary habit was 2.01 (1.63–2.47, p<0.001). Participants with decreased consumption of meat, fish, seaweed and mushroom, and fruits and those with increased consumption of eggs, bread, and noodles tended to be frail.ConclusionThe nutritional intervention for frail older people should be strengthened during the pandemic.
Highlights
The coronavirus disease (COVID-19) pandemic has resulted in reduced physical activity and social interaction
We found more older adults who decreased their intake of meat, fish, and rice as opposed to those who increased their intake of these foods
On comparing the frail and non-frail groups, those who consumed less meat, fish, seaweed and mushrooms, and fruits were more frequently frail than non-frail; whereas, those who consumed more egg, bread, and noodles were more likely to be in the frail group than in the non-frail group
