ABSTRACT
Background and aim:
Given the importance of dietary habits in the immune system, the current study aimed at investigating the association between Dietary Approach to Stop Hypertension (DASH) diet and risk of hospitalization due to COVID-19.Methods:
Dietary data of 141 patients with COVID-19 were collected using 147-item food frequency questionnaire. DASH score in this cross-sectional study was calculated based on eight components, including fruits, vegetables, legumes and nuts and seeds, whole grains, low-fat dairy, red or processed meats, sweetened beverages, and sodium. Multivariable logistic regression models were applied to estimate the OR and 95% CI for hospitalization due to COVID-19 in each tertile of DASH score.Results:
Mean ± SD of DASH score in inpatients (n=74) and outpatients (n= 87) was 22.5 ± 4.57 and 25.34 ± 4.23, respectively. The risk of hospitalization in the highest tertile of DASH score was 81% lower than the lowest tertile (OR=0.19, 95%CI 0.07-0.55, P trend = 0.001 after adjustment for age, sex, BMI, energy intake). Also, more intake of fruits, vegetables and low-fat dairy products and less intake of sodium, red and processed meat were each significantly associated with reduced risk of hospitalization due to COVID-19.Conclusions:
Our data provide evidence that adherence to DASH-style diet was associated with lower risk of hospitalization due to COVID-19.
