Table 2 Test–reliability based on intraclass correlation coefficient for Hausa IPAQ-LF, overall and selleck chem by gender Similarly, socioeconomic status differences were observed in the reliability coefficients of the modified
IPAQ-LF (table 3). Across all domains of PA, reliability coefficients were substantially higher among participants with less than secondary school education (ICC from 0.77 (sitting activity) to 0.92 (leisure activity)) compared to those with secondary school education (ICC from 0.28 (active transport) to 0.58 (occupational activity)) and those with higher than secondary school education (ICC from 0.23 (sitting activity) to 0.67 (active transport)). While reliability coefficients were higher for overall PA (ICC=0.80, 95% CI 0.71 to 0.86), active transport (ICC=0.83, 95% CI 0.74 to 0.88), occupational PA (ICC=0.79, 95% CI 0.70 to 0.86) and leisure-time PA (ICC=0.79, 95% CI 0.69 to 0.85) among participants who were employed compared to their unemployed counterparts, it was higher for domestic PA (ICC=0.65, 95% CI 0.43 to 0.79) and sitting time (ICC=0.68, 95% CI 0.36 to 0.83) among participants who were unemployed than
in the employed subgroup. Table 3 Socioeconomic status differences in test–retest reliability of the Hausa IPAQ-LF (N=180) Figures 1–3 (Bland-Altman plots) illustrate the agreement in the scores (min/week) of total PA, MVPA and sitting between the first and second administrations of Hausa IPAQ-LF. For total PA, the mean difference was 106.7 min/week, with wide 95% limits of agreement (−762.2 to 965.6 min/week). For MVPA, the mean difference was about one and half hours per week (91.6 min/week), and also demonstrating wide 95% limits of agreement (−744.5 to 927.7 min/week). For sitting time, the mean difference was small (26 min/week) and the 95% limits of agreement ranged from −2178.1 to 2230.9 min/week. Figure 1 Bland-Altman plot min/week reported
in total physical activity (PA) for the first and second administrations of Hausa IPAQ-LF. Mean difference: 106.7±2 SD=−762.2 to 965.6. Figure 2 Bland-Altman plot min/week reported in moderate-to-vigorous physical activity (MVPA) for the first and second administrations AV-951 of Hausa IPAQ-LF. Mean difference: 91.6±2 SD=−744.5 to 927. Figure 3 Bland-Altman plot min/week reported in sitting for the first and second administrations of Hausa IPAQ-LF. Mean difference: 26.4=±2 SD=−2178.1 to 2230.9. Table 4 shows the patterns of PA across sociodemographic subgroups during the first (IPAQ1) and second (IPAQ2) administrations of the modified IPAQ-LF. Overall and across all stratified variables, time spent in PA reported during the first administration tends to be higher than that reported during the second administration. At both time points, men reported significantly (p<0.05) higher mean time (min/week) in active transportation, occupational PA and leisure-time PA than women.
