AbstractPurpose Environmental and lifestyle factors that affect oxidative stress and inflammation may influence telomere length (TL). There are limited data to relate dietary patterns with TL. This study examined the association of various dietary patterns with TL in Chinese older adults. Methods We conducted a cross-sectional analysis and performed multivariate linear regression analyses using available data from 1981 (965 men, 1016 women) community-dwelling Chinese adults aged 65 years and over in Hong Kong. The interviewer administered questionnaires that covered dietary intake estimation and dietary pattern generation from the food frequency questionnaire, demographic and lifestyle factors, and self-reported medical history. TL was measured by quantitative real-time polymerase chain reaction. Results None of the dietary pattern scores including the Diet Quality Index-International (DQI-I) score, the Dietary Approaches to Stop Hypertension (DASH) score, the Mediterranean-DASH Intervention for Neurodegenerative Delay Diet (MIND) score, the Mediterranean Diet Score (MDS), the Okinawan diet score, as well as the "vegetables-fruits" pattern score, the "snacks-drinks-milk" pattern score, and the "meat-fish" pattern score were associated with TL in the age- and sex-adjusted model and the multivariate adjusted model. Conclusion Our findings suggest a minimal role of dietary patterns in telomere length in community-dwelling Chinese older adults.
