Frequency of Dietary Intake and Physical Activity in Older Adults : A Cross-Sectional Study

Background: Evidence shows that diet is associated with physical activity. However, there has been a lack of studies addressing it in a population of older adults. Therefore, the main purpose of this study was to explore associations between various frequencies of dietary intake and physical activity in older adults. Methods: In this cross-sectional study, the participants were 810 older adults aged ≥85. Frequency of dietary intake and the level of physical activity were assessed using the Elderly Diet Index score and International Physical Activity questionnaire. Mutual associations were examined using generalized estimating equations with a logistic regression model. Results: ”Optimal” intake of fish and seafood (OR (odds ratio) = 1.40 ; 95% CI (95 percent confidence interval) 1.01 to 2.00), fruits (OR = 2.10 ; 95% CI 1.45 to 3.02), legumes (OR = 1.73 ; 95% CI 1.19 to 2.50), olive oil (OR = 1.83 ; 95% CI 1.09 to 3.08) and bread (OR = 4.62 ; 95% CI 3.05 to 6.99) and the total Elderly Diet Index score (OR = 4.99 ; 95% CI 3.20 to 7.70) were associated with ”sufficient” physical activity. When all dietary components were entered simultaneously into the model, ”optimal” intakes of meat (OR = 1.73 ; 95% CI 1.10 to 2.71), fish and seafood (OR = 2.26 ; 95% CI 1.46 to 3.51), cereals (OR = 1.75 ; 95% CI 1.02 to 3.25), fruits (OR = 1.52 ; 95% CI 1.02 to 2.26), legumes (OR = 1.48 ; 95% CI 1.10 to 1.93), and bread (OR = 5.14 ; 95% CI 3.24 to 8.15) were associated with ”sufficient” physical activity. Conclusions: Our study shows that the total Elderly Diet Index score is the strongest predictor associated with ”sufficient” physical activity in a population of older adults. Thus, policies aiming to improve overall diet in order to achieve higher levels of physical activity are warranted.
