Objective To evaluate the comprehensive intervention effect in a high-risk elderly population with cognitive impairment in Beijing, thus providing a scientific basis for exploring effective intervention models.

Methods In April 2024, a stratified multistage cluster sampling method was used to select 222 elderly individuals aged 65–80 years from communities in eight districts—Dongcheng district, Chaoyang district, Fengtai district, Haidian district, Tongzhou district, Shunyi district, Daxing district, and Huairou district—of Beijing for testing with the Eight-item Informant Interview to Differentiate Aging and Dementia (AD8) and the Mini-Mental State Examination (MMSE). From April to October 2024, a six-month comprehensive intervention (including chronic disease management, Baduanjin exercise, and educational games) was conducted for high-risk elderly individuals with AD8 scores ≥ 2. The intervention effect was evaluated by comparing the AD8 and MMSE scores before and after the intervention.

Results  Among the 203 high-risk elderly individuals with cognitive impairment finally included in the analysis in Beijing, the average AD8 scores were (3.44±1.44) and (2.65±2.28) points and the average MMSE scores were (25.90±3.94) and (27.96±2.66) points before and after the intervention, respectively. The differences in average AD8 and MMSE scores before and after the intervention were statistically significant (both P<0.001). After the intervention, 129 (63.55%) and 131 (64.53%) high-risk elderly individuals with cognitive impairment showed improvement in AD8 scores and MMSE scores, respectively.

Conclusions The comprehensive intervention method has a positive effect on the cognitive ability of high-risk elderly people with cognitive impairment in Beijing, and this intervention measure should be actively promoted in the future work.
