[Psychosocial traits associated with maintenance of physical activity 12months after a pulmonary rehabilitation program - An exploratory study].

Abstract

Introduction: After a pulmonary rehabilitation (PR) program, 30 to 70% of patients fail to pursue maintenance of physical activity. This study aimed to identify psychosocial markers associated with MPA subsequent to an initial outpatient PR course (≥10 sessions).

Material and methods: Patients were enrolled in an exploratory quantitative monocentric retrospective study. Clinical data were extracted from the PR center database. Psychosocial data were collected by a postal questionnaire. A telephone interview assessed maintenance of physical activity at 12months, which was defined as self-reported physical activity≥30min,≥2 times per week.

Results: Among 134 patients (age 67years [31-88], 88% COPD, FEV1 55% [25-103]), 95 (71%) reported maintenance of physical activity at 12months. Multivariate logistic regression analysis showed that compared with subjects without maintenance of physical activity, those with the latter: (1) reported greater self-efficacy and internal locus of control, (2) considered their health status as less severe and (3) resided closer to the PR center.

Conclusion: Patient-declared self-efficacy and locus of control internalization were independently associated with maintenance of physical activity 12months after an initial PR program.
