Do Health-Related Quality of Life and Pain-Coping Strategies Explain the Relationship between Older Women Participants in a Pilates-Aerobic Program and Bodily Pain? A Multiple Mediation Model

This study (1) analyzes the differences between non-participating and participating older women in terms of clinical characteristics, pain coping strategies, health-related quality of life and physical activity (PA); (2) studies the associations between non-participants and participants, clinical characteristics, pain coping strategies, HRQoL and bodily pain and PA; and (3) determines whether catastrophizing, physical role, behavioural coping, social functioning and emotional role are significant mediators in the link between participating in a Pilates-aerobic program (or not) and bodily pain. The sample comprised 340 older women over 60 years old. Participants of the present cross-sectional study completed measures of clinical characteristics: HRQoL using the SF-36 Health Survey, pain-coping strategies using the Vanderbilt Pain Management Inventory (VPMI) and PA using the International Physical Activity Questionnaire (IPAQ). Significant differences between non-participants and participants, were found in clinical characteristics, pain-coping strategies (both, p < 0.05), HRQoL (p < 0.01), and PA (p < 0.001). Moreover, catastrophizing support mediated the link between non-participants and participants and bodily pain by 95.9% of the total effect; 42.9% was mediated by PA and 39.6% was mediated by behavioural coping. These results contribute to a better understanding of the link between PA and bodily pain.
