AB  - BACKGROUND: Frailty has emerged as a global health burden with increased 
      population aging. A diverse diet is essential for an adequate and balanced supply 
      of nutrients. However, limited evidence supports the relationship between dietary 
      diversity and frailty. We therefore assessed the associations of dietary 
      diversity with the risk of frailty. METHODS: We used the Chinese Longitudinal 
      Healthy Longevity Survey to analyze a prospective cohort of Chinese older adults. 
      A total of 1948 non-frail older adults were included in the final sample. 
      Participants were categorized into groups with high or low dietary diversity 
      scores (DDSs) using a food frequency questionnaire. A Generalized Estimating 
      Equation were used to estimate risk ratios (RRs) and 95% confidence intervals 
      (CIs) for determining frailty incidence. RESULTS: Among 1,948 participants, 381 
      had frailty with the prevalence of 19.56% during the 3-year follow-up period. 
      Compared with the low DDS group, the high DDS group exhibited a lower risk of 
      frailty (RR, 0.72; 95% CI: 0.57-0.91). Compared with those with a consistently 
      low DDS, the RR of participants with a consistently high DDS for frailty was 0.56 
      (95% CI: 0.42-0.74). Moreover, meat, beans, fish, nuts, fresh fruits, and fresh 
      vegetables were inversely associated with frailty. In stratified analysis, a 
      consistently high DDS, compared with a consistently low DDS, reduced the risk of 
      frailty for people aged 65-79 years and those living in town and rural areas. 
      CONCLUSION: This study found a prospective association between dietary diversity 
      and frailty among Chinese older adults. These findings stressed that it is 
      important to improve dietary diversity for older adults to promote healthy 
      ageing, particularly for young older adults and in town and rural areas.
