The Association Between Impaired Dyadic Coping and Frailty in Elderly Patients With Hypertension: A Latent Profile Analysis.

Background: Lifelong hypertension highlights the importance of dyadic engagement in coping with the disease. Although dyadic coping is heterogeneous in patients with other diseases, little is known about it in elderly patients with hypertension. In addition, whether impaired dyadic coping is associated with frailty has yet to be elucidated.

Objectives: The aim of this study was to investigate the latent profiles and characteristics of dyadic coping and the potential association between impaired dyadic coping and frailty in elderly patients with hypertension.

Methods: We recruited a total of 741 elderly patients with hypertension. Latent profile analysis was then used to identify the best-fitting model. Then, we used regression analysis to determine profile predictors and identify the association between impaired dyadic coping and frailty.

Results: The 5-profile model was considered to be the best-fitting model, as follows: profile 1, severely impaired dyadic coping; profile 2, mildly impaired dyadic coping; profile 3, normal dyadic coping; profile 4, better dyadic coping; and profile 5, the highest dyadic coping. In the fully adjusted model, the probability of frailty was 1.94-fold higher in the mildly impaired dyadic coping group (odds ratio, 1.94; 95% confidence interval, 1.09-3.47) and 2.66-fold higher in the severely impaired dyadic coping group (odds ratio, 2.66; 95% confidence interval, 1.11-6.39).

Conclusions: We identified heterogeneity in dyadic coping and demonstrated that impaired dyadic coping was associated with frailty. Those at risk of dyadic coping impairment need to be identified early, followed by dyadic coping-based interventions to prevent or delay frailty.
