001) more time (min/week) in domestic PA than men (IPAQ1=236.9 vs 82.3, IPAQ2=195.5 vs 52.4). For educational status, participants who had lower than secondary school education compared to those with at least secondary school education reported statistically significant higher mean www.selleckchem.com/products/Gemcitabine-Hydrochloride(Gemzar).html time (min/week) at both time points for total PA, active transport, occupational PA, walking and vigorous intensity activity compared to those with at least secondary school education. While participants who were employed reported statistically significant (p<0.05) greater time (min/week) in total PA

(IPAQ1=441.1 vs 285.1, IPAQ2=359.4 vs 141.0), active transportation (IPAQ1=43.8 vs 21.1, IPAQ2=36.9 vs 18.3) and work PA (IPAQ1=195.5 vs 41.8, IPAQ2=164.1 vs 40.1) than those who were unemployed, the unemployed reported statistically significant (p<0.05) higher time in domestic activity (IPAQ1=210.6 vs 132.1, IPAQ2=205.0 vs 112.6) compared to the employed. Table 4 Differences in time spent in physical activity overall, and by gender and socioeconomic status subgroups Construct validity Overall, correlations between energy expenditure (MET-min/week) according to the modified IPAQ-LF and anthropometric and biological measures were statistically significant

in the expected direction for all domains and intensities of PA, except for occupation and active transport domains, and walking (table 5). In the full sample, domestic PA was mainly related with SBP (r=−0.27, p<0.01) and DBP (r=−0.17, p< 0.05), while leisure PA and total PA were only related with SBP (r=−0.16, p<0.05) and BMI (r=−0.29, p<0.01), 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). In the gender-based analyses, total PA, domestic PA and sedentary time were more consistently related with anthropometric and biological variables. The strongest r value (−0.41) was found for the relationship between total PA and BMI for the male subgroup. The r value of −0.23 was reached between total PA and DBP for the women subgroup. Only

in women was domestic PA significantly related with BMI (r=−0.23), Anacetrapib DBP (r=−0.20) and SBP (r=−0.31). Leisure-time PA (r=−0.39) and occupational PA (r=−0.22) were significantly related with BMI only in men. The rho value for the relationship between sitting time and BMI was slightly higher in women (r=0.19) than in men (r=0.15). Table 5 Construct validity of Hausa IPAQ-LF: Spearman correlations between energy expenditure (MET×min/week) from Hausa IPAQ-LF, and anthropometric and biological variables (N=180) Discussion This study examined the reliability and an aspect of validity of a modified version of the IPAQ-LF in Nigeria. The findings generally indicated acceptable test–retest reliability and modest construct validity for items of the modified IPAQ-LF among Nigerian adults.
