The Role of Dietary Patterns in the Contribution of Cardiorespiratory Fitness in Community-Dwelling Older Chinese Adults in Hong Kong
Publication in refereed journal


摘要Objective: We examined the influence of various dietary patterns on cardiorespiratory fitness (CRF) expressed as peak oxygen uptake (VO(2)peak), taking into account demographics and lifestyle risk factors.

Design: Prospective cohort study.

Participants and methods: We conducted multivariate linear regression analyses using available data from a cohort of community-dwelling older Chinese adults (752 men, 483 women) in Hong Kong. Baseline interviewer-administered questionnaires covered dietary intake estimation and dietary pattern generation from the food frequency questionnaire, demographic and lifestyle factors, self-reported medical history, as well as frailty status. VO(2)peak at the 7-year follow-up was measured using symptom-limited maximal exercise testing on an electrically braked bicycle ergometer.

Results: In men, baseline Diet Quality IndexeInternational (DQI-I) score (beta = 0.044, P = .013) and Okinawan diet score (beta = 0.265, P = .014) was independently associated with age-adjusted VO(2)peak at the 7-year follow-up. The significant association was only retained for the Okinawan diet score in the multivariate adjusted model (beta = 0.227, P = .039). Dietary pattern scores including the Dietary Approaches to Stop Hypertension (DASH) score, Mediterranean-DASH Intervention for Neurodegenerative Delay Diet score, Mediterranean Diet Score, and 3 other pattern scores derived by factor analysis were not associated with VO(2)peak. In women, none of the dietary pattern scores at baseline was associated with VO(2)peak in both the age-adjusted and multivariate-adjusted models.

Conclusions/Implications: A higher Okinawan diet score was associated with a higher 7-year CRF in community-dwelling Chinese older men. Further studies are warranted to examine the underlying mechanisms on how the Okinawan diet influences CRF. (C) 2018 AMDA - The Society for Post-Acute and Long-Term Care Medicine.
