Background: The benefits of physical activity have been largely demonstrated in healthy subjects and people with chronic diseases. Particularly, in stroke survivors, increasing physical activity and decreasing sedentary time is one of the main strategies to manage the long-term rehabilitation. Therefore, it is essential to assess the physical activity levels in stroke survivors and to develop interventions to promote an active lifestyle. The International Physical Activity Questionnaire (IPAQ) is a questionnaire frequently used in healthy subjects and different patient groups. However, this questionnaire has not been validated in African francophone countries, where there is a lack of valid, reliable and accessible tools to assess physical activity. Recently, we have examined the applicability of this questionnaire in Benin context. As result, cultural and linguistic adaptations of the items led to the creation of an experimental Benin version of the IPAQ Long-Form (IPAQ-LF Benin).

Purpose: To investigate the validity and the reliability of a Benin French version of the IPAQ Long-Form (IPAQ-LF Benin) in healthy subjects and people with stroke.

Methods: 60 healthy subjects and 60 individuals with stroke (77 males; mean age: 52.7±11.7 years old) were recruited in Benin, a West Africa francophone country. In addition to a 7-day activity monitoring from waking up in the morning to bedtime using a wrist-worn device, participants completed the interview-based IPAQ-LF Benin. The IPAQ-LF Benin was completed twice over two days for test-retest reliability that was assessed through intra-class correlation coefficient (ICC). For construct validity, Spearman correlation coefficients (r) were calculated between IPAQ-LF Benin scores and 7-day steps respectively for total sample, and by subgroups (healthy subjects, and individuals with stroke, separately).

Results: The IPAQ-LF Benin showed excellent correlation with daily steps for total sample (r=0.96; p 0.001), in healthy subjects (r=0.94; p 0.001), and in the individuals with stroke (r=0.91; p 0.001). Also, IPAQ-LF Benin demonstrated excellent test-retest reliability in the 3 groups with ICC of 0.993; 0.986; and 0.996 (p 0.001).

Conclusion(s): These results suggest that IPAQ-LF Benin is a valid and reliable measure of physical activity in healthy subjects and people with stroke.

Implications: This project makes available a valid, reliable and accessible tool to measure the physical activity level of individuals in Benin. The use of this questionnaire will help Beninese health professionals, including physiotherapists to adjust interventions to promote an active lifestyle as needed, particularly in people with stroke.
