摘要
Introduction: Dietary behavior is a central modifiable risk factor for human health. This study examined the longitudinal relationship between dietary habits and self-rated health among the oldest-old Chinese. @@@ Methods: Participants aged 80 years and above (N = 7273) were first interviewed in 1998 and followed in subsequent waves 2-3 years apart till 2011-2012 in the Chinese Longitudinal Healthy Longevity Survey. Cox proportional hazards regressions were performed to estimate the effects of dietary habits on poor self-rated health, adjusting for various individual characteristics. @@@ Results: Compared to those who rarely/never consumed fruit, vegetable, meat, egg, and soybean-derived product, participants consuming such products almost every day were 28%, 20%, 32%, 16%, and 16% less likely to report poor self-rated health during follow-up, respectively. Compared to those who rarely/never consumed fruit, meat, fish, soybean-derived product, and tea, participants consuming such products occasionally were 12%, 24%, 11%, 15%, and 14% less likely to report poor self-rated health during follow-up, respectively. Compared to those who rarely/never consumed sugar, participants consuming sugar almost every day were 14% more likely to report poor self-rated health during follow-up. The effects of dietary habits on self-rated health to some extent differed by sex. @@@ Conclusions: Oldest-old Chinese could gain health benefit from regular consumption of fruit, vegetable, meat, fish, egg, soybean-derived product, and tea; whereas their sugar consumption may need to be reduced. Future research is warranted to establish the recommended daily nutrient allowances for the oldest-old adults and better address the nutritional needs of this vulnerable population.
