Examining the reliability and validity of a modified version of the International Physical Activity Questionnaire, long form (IPAQ-LF) in Nigeria: a cross-sectional study.

ABSTRACT:

Objectives

To investigate the reliability and an aspect of validity of a modified version of the long International Physical Activity Questionnaire (Hausa IPAQ-LF) in Nigeria.

Design

Cross-sectional study, examining the reliability and construct validity of the Hausa IPAQ-LF compared with anthropometric and biological variables.

Setting

Metropolitan Maiduguri, the capital city of Borno State in Nigeria.

Participants

180 Nigerian adults (50% women) with a mean age of 35.6 (SD=10.3) years, recruited from neighbourhoods with diverse socioeconomic status and walkability.

Outcome measures

Domains (domestic physical activity (PA), occupational PA, leisure-time PA, active transportation and sitting time) and intensities of PA (vigorous, moderate and walking) were measured with the Hausa IPAQ-LF on two different occasions, 8 days apart. Outcomes for construct validity were measured body mass index (BMI), systolic blood pressure (SBP) and diastolic blood pressure (DBP).

Results

The Hausa IPAQ-LF demonstrated good test-retest reliability (intraclass correlation coefficient, ICC>75) for total PA (ICC=0.79, 95% CI 0.65 to 0.82), occupational PA (ICC=0.77, 95% CI 0.68 to 0.82), active transportation (ICC=0.82, 95% CI 0.75 to 0.87) and vigorous intensity activities (ICC=0.82, 95% CI 0.76 to 0.87). Reliability was substantially higher for total PA (ICC=0.80), occupational PA (ICC=0.78), leisure-time PA (ICC=0.75) and active transportation (ICC=0.80) in men than in women, but domestic PA (ICC=0.38) and sitting time (ICC=0.71) demonstrated more substantial reliability coefficients in women than in men. For the construct validity, domestic PA was significantly related mainly with SBP (r=-0.27) and DBP (r=-0.17), and leisure-time PA and total PA were significantly related only with SBP (r=-0.16) and BMI (r=-0.29), respectively. Similarly, moderate-intensity PA was mainly related with SBP (r=-0.16, p<0.05) and DBP (r=-0.21, p<0.01), but vigorous-intensity PA was only related with BMI (r=-0.11, p<0.05).

Conclusions

The modified Hausa IPAQ-LF demonstrated sufficient evidence of test-retest reliability and may be valid for assessing context specific PA behaviours of adults in Nigeria.

Project description:BackgroundThe International Physical Actvity Questionnaire (IPAQ) is a validated tool for physical activity assessment used in many countries however no Arabic version of the long-form of this questionnaire exists to this date. Hence, the aim of this study was to cross-culturally adapt and validate an Arabic version of the long International Physical Activity Questionnaire (AIPAQ) equivalent to the French version (F-IPAQ) in a Lebanese population.MethodsThe guidelines for cross-cultural adaptation provided by the World Health Organization and the International Physical Activity Questionnaire committee were followed. One hundred fifty-nine students and staff members from Saint Joseph University of Beirut were randomly recruited to participate in the study. Items of the A-IPAQ were compared to those from the F-IPAQ for concurrent validity using Spearman's correlation coefficient. Content validity of the questionnaire was assessed using factor analysis for the A-IPAQ's items. The physical activity indicators derived from the A-IPAQ were compared with the body mass index (BMI) of the participants for construct validity. The instrument was also evaluated for internal consistency reliability using Cronbach's alpha and Intraclass Correlation Coefficient (ICC). Finally, thirty-one participants were asked to complete the A-IPAQ on two occasions three weeks apart to examine its test-retest reliability. Bland-Altman analyses were performed to evaluate the extent of agreement between the two versions of the questionnaire and its repeated administrations.ResultsA high correlation was observed between answers of the F-IPAQ and those of the A-IPAQ, with Spearman's correlation coefficients ranging from 0.91 to 1.00 (p < 0.05). Bland-Altman analysis showed a high level of agreement between the two versions with all values scattered around the mean for total physical activity (mean difference = 5.3 min/week, 95% limits of agreement = -145.2 to 155.8). Negative correlations were observed between MET values and BMI, independent of age, gender or university campus. The A-IPAQ showed a high internal consistency reliability with Cronbach's alpha ranging from 0.769-1.00 (p < 0.001) and intraclass correlation coefficient (ICC) ranging from 0.625-0.999 (p < 0.001), except for a moderate agreement with the moderate garden/yard activity (alpha = 0.682; ICC = 0.518; p < 0.001). The A-IPAQ had moderate-to-good test-retest reliability for most of its items (ICC ranging from 0.66-0.96; p < 0.001) and the Bland-Altman analysis showed a satisfactory agreement between the two administrations of the A-IPAQ for total physical activity (mean difference = 99.8 min/week, 95% limits of agreement = -1105.3; 1304.9) and total vigorous and moderate physical activity (mean difference = -29.7 min/week, 95% limits of agreement = -777.6; 718.2).ConclusionThe modified Arabic version of the IPAQ showed acceptable validity and reliability for the assessment of physical activity among Lebanese adults. More studies are necessary in the future to assess its validity compared to a gold-standard criterion measure.

Project description:BackgroundAccurate assessment of physical activity is important in determining the risk for chronic diseases such as cardiovascular disease, stroke, type 2 diabetes, cancer and obesity. The absence of culturally relevant measures in indigenous languages could pose challenges to epidemiological studies on physical activity in developing countries. The purpose of this study was to translate and cross-culturally adapt the Short International Physical Activity Questionnaire (IPAQ-SF) to the Hausa language, and to evaluate the validity and reliability of the Hausa version of IPAQ-SF in Nigeria.MethodsThe English IPAQ-SF was translated into the Hausa language, synthesized, back translated, and subsequently subjected to expert committee review and pre-testing. The final product (Hausa IPAQ-SF) was tested in a cross-sectional study for concurrent (correlation with the English version) and construct validity, and test-retest reliability in a sample of 102 apparently healthy adults.ResultsThe Hausa IPAQ-SF has good concurrent validity with Spearman correlation coefficients (?) ranging from 0.78 for vigorous activity (Min Week-1) to 0.92 for total physical activity (Metabolic Equivalent of Task [MET]-Min Week-1), but poor construct validity, with cardiorespiratory fitness (? = 0.21, p = 0.01) and body mass index (? = 0.22, p = 0.04) significantly correlated with only moderate activity and sitting time (Min Week-1), respectively. Reliability was good for vigorous (ICC = 0.73, 95% C.I = 0.55-0.84) and total physical activity (ICC = 0.61, 95% C.I = 0.47-0.72), but fair for moderate activity (ICC = 0.33, 95% C.I = 0.12-0.51), and few meaningful differences were found in the gender and socioeconomic status specific analyses.ConclusionsThe Hausa IPAQ-SF has acceptable concurrent validity and test-retest reliability for vigorous-intensity activity, walking, sitting and total physical activity, but demonstrated only fair construct validity for moderate and sitting activities. The Hausa IPAQ-SF can be used for physical activity measurements in Nigeria, but further construct validity testing with objective measures such as an accelerometer is needed.
