摘要

Background

The concept of healthy aging centers on maintaining and enhancing older adults’ intrinsic capacities to optimize functionality. This study begins with intrinsic capacity, uses the WHO ICOPE framework to assess its decline, and examines the interrelationships among family function, intrinsic capacity, and quality of life among older adults residing in the community who have been diagnosed with type 2 diabetes. It also verifies the mediating effect of intrinsic capacity, which may inform interventions to improve their quality of life.

Methods

Older adults with type 2 diabetes from three communities in Jinzhou City, Liaoning Province, were selected as research subjects using convenience sampling. A self-designed questionnaire, Family Functioning Scale (FACES), Quality of Life Specific Scale for Diabetic Patients (DSQL), and an intrinsic capacity assessment tool were used. SPSS 27.0 and Amos 28.0 were used for data analysis. Applied a structural equation framework to explore directional links among constructs; indirect influence estimated via repeated resampling (Bootstrap).

Results

A total of 328 older adults (mean age 71.34, SD = 6.82) participated in the WHO ICOPE Step 1 brief screening. After Step 2, complete assessment, 75.0% (246) of subjects had a decline in intrinsic capacity, and 81.3% had impaired“vitality”. Family function is significantly negatively correlated with both quality of life (r= -0.572, P < 0.01) and intrinsic capacity (r=-0.460, P < 0.01), with higher scores indicating worse status. Intrinsic capacity exhibits a positive correlation with the quality of life (r = 0.542, P < 0.01). The functioning of the family unit was associated with quality of life and partially mediated by intrinsic capacity, accounting for 20.3% of the total effect.

Conclusions

The intrinsic capacity of older adults with type 2 diabetes is generally impaired. Family function is directly and indirectly associated with quality of life. Routine implementation of the ICOPE assessment at the community level is recommended to identify early impairments in intrinsic capacity dimensions. By strengthening family adaptability and implementing personalized exercise and nutritional interventions, the intrinsic capacity and quality of life of older adults may be improved.
