Why the study?

Previous studies on illness perception and self-management mainly focused on single illnesses, while most adults over 60 have multimorbidity including CHD and DM.

Population

210 older adults aged ≥60 years with CHD and DM from two tertiary hospitals in Guangzhou, China

Comparison

Multiple illness perceptions of CHD and DM and their moderation effects on self-management

Design

Cross-sectional study

Key result

Illness perceptions of coronary heart disease and diabetes mellitus were significantly correlated with self-management of both conditions (|r|=0.136-0.484, P<0.05).

Overview

Associations may inform integrated self-management support in comorbid CHD-DM; leaves open causality and needs prospective trials before practice change.

Key Points

  • To explore the relationships between illness perceptions and self-management behaviors, and evaluate moderation effects among illness perceptions, in older adults with concurrent coronary heart disease and diabetes mellitus.
  • Conducted a cross-sectional study from December 2022 to March 2023 enrolling 210 older adults (aged ≥60 years) with concurrent coronary heart disease and diabetes mellitus from cardiovascular wards of two tertiary hospitals in Guangzhou, China.
  • Administered the Brief Illness Perception Questionnaire, Coronary Artery Disease Self-management Scale, and Diabetes Self-care Scale, evaluating data using Pearson correlation and hierarchical linear regression analyses.
  • Illness perceptions correlated significantly with disease-specific self-management for coronary heart disease (|r| = 0.136 to 0.424, P < 0.05) and diabetes mellitus (|r| = 0.146 to 0.484, P < 0.05).
  • Diabetes identity significantly moderated the relationship between coronary heart disease identity and daily life management of coronary heart disease (P < 0.05).
  • Coronary heart disease coherence significantly moderated the relationship between diabetes coherence and diabetes medication adherence (P < 0.05).

Population
210 older adults aged ≥60 years with concurrent coronary heart disease and diabetes mellitus recruited from two tertiary hospitals.
O
Outcome
Self-management of CHD and DM as measured by the Coronary Artery Disease Self-management Scale and the Diabetes Self-care Scalepatient reported

Main Result

Effect estimate: |r|=0.136-0.484

p-value: p=< 0.05

In older adults with concurrent CHD and DM, illness perceptions of both conditions interact to influence self-management, highlighting the need for integrated psycho-educational programs.

Wang et al. (2026) conducted a cross-sectional in concurrent coronary heart disease and diabetes mellitus (n=210). Illness perceptions of CHD and DM was evaluated on Self-management of CHD and DM (|r|=0.136-0.484, p=< 0.05). Illness perceptions of coronary heart disease and diabetes mellitus were significantly correlated with self-management of both conditions (|r|=0.136-0.484, P<0.05).
