Association of Intrinsic Capacity with Frailty in Community-Dwelling Older People, Lamphun Province: A Cross-Sectional Study
Main Article Content
Abstract
ABSTRACT
Background: To study the relationship between six domains of intrinsic capacity (IC) and frailty among community-dwelling older adults in Mueang District, Lamphun Province
Study Design: Cross-Sectional Study
Methods: A stratified random sampling of homebound elderly participants was selected from each subdistrict. The evaluation included six domains of intrinsic capacity assessment and frailty, measured by the Thai Frailty Index (TFI).
Results: Three hundred and fifty elderly participants with an average age of 77.72 years (range 60-101) were included. The majority, 242 participants (69.14%), were females, Participants were categorized into three groups: 70 in the robust group (20.11%), 113 in the pre-frail group (32.47%), and 165 in the frail group (47.41%). Significant associations were found between frailty and locomotor capacity (short physical performance battery (SPPB) ≤ 8) (odds ratio (OR) = 9.31, p < 0.001), cognitive capacity (OR = 9.01, p < 0.001), depression (OR = 5.35, p < 0.001), nutrition risk (OR = 4.15, p < 0.001), hearing capacity (OR = 2.05, p < 0.001) and vision capacity (OR = 2.01, p = 0.011). The locomotion test had the highest area under the curve (AUC) at 0.72. The other dimensions showed moderate accuracy in predicting frailty.
Conclusions: This study demonstrates that combined assessment of intrinsic capacities and frailty in older adults is necessary for personalized care planning and health promotion.
