Objective To investigate the association between dietary diversity and intrinsic capacity among community-dwelling older adults.Methods A cross-sectional study was conducted from February to August 2023,involving 745 elderly people aged ≥60 years old in Beijing communities by convenient sampling method.The dietary diversity score(DDS)was constructed based on eight food groups,including meat,eggs,fish,legumes,milk or dairy products,yogurt,vegetables,and fruits.The intrinsic capacity among elderly people was evaluated according to the recommendations of WHO,and divided into a group with good intrinsic capacity(4-5 points)and a group with poor intrinsic capacity(0-3 points).Binary Logistic regression analysis was used to explore the association between DDS and to assess the impact of various dietary components on the intrinsic capacity of the elderly adults.Results The DDS score of the group with good intrinsic capacity(4.00±1.49)was significantly higher than that of the group with poor intrinsic capacity(3.73±1.55)(t=2.233,P=0.026).DDS was identified as a protective factor for the intrinsic capacity of the elderly(OR=0.836,95％CI=0.745-0.938,P=0.002).The intake frequency of meat(x2=10.127,P=0.001)and fruit(x2=7.632,P=0.006)was higher compared to the group with lower intrinsic capacity.Further Logistics regression analysis showed that insufficient intake of vegetables(OR=0.502,95％CI=0.256-0.986,P=0.045)and fruits(OR=0.575,95％CI=0.391-0.847,P=0.005)was associated with poorer intrinsic capacity.Conclusions DDS is associated with intrinsic capacity in elderly adults.Elderly people in the community should change their single dietary structure and increase dietary diversity to reduce the risk of decline in intrinsic capacity.
