Adherence to the Dietary Approaches to Stop Hypertension (DASH) diet has been associated with sleep quality. However, its relationship with sleep-disordered breathing (SDB) remains unknown. This study aimed to explore the association between the DASH diet and SDB using data from a community-based survey among adults in Suzhou, Eastern China. We conducted a cross-sectional analysis of the Suzhou Food Consumption and Health Survey in 2018–2020. Dietary intake was measured by a validated FFQ. The association between the DASH diet and SDB was estimated by multivariable logistic regression analysis. In addition, subgroup analysis and sensitivity analysis were performed to reinforce our findings. A total of 3939 participants were included in the final analysis. Participants in the upper quintile of the DASH score consumed more fruits, vegetables, nuts and legumes, whole grains, and dairy products, and less Na, red/processed meats, and sweetened beverages. The OR for the highest compared with the lowest quintile of the DASH score was 0·68 (95 % CI 0·52, 0·88; P
for trend = 0·004) for SDB after multivariable adjustment. Of the eight DASH components, vegetables, nuts and legumes, and dairy products were inversely associated with SDB. The associations were similar in subgroups by age, sex, BMI, smoking, alcohol drinking, hypertension, diabetes and hyperlipidaemia. Adherence to the DASH diet was independently associated with decreased odds of self-reported SDB. Our novel results expand previous findings on diet and sleep and suggest the possibility of improving SDB by enhancing diet quality.
