Regular PA is associated with a decrease in all‑causes of mortality irrespective of gender. The study was conducted to investigate the validity and an aspect of reliability of a modified version of the International<br />Physical Activity Questionnaire (IPAQ) in the Indian subcontinent (InS). </span></p><p><span class="fontstyle0"><strong>Methods</strong>: </span><span class="fontstyle2">Cross‑sectional study, to evaluate the validity and reliability of the InS IPAQ‑LF compared with a range of biological variables. In total, 198 participants (50% women) with a mean age of 35.6 (SD = 10.3) years selected from neighborhoods with variable socioeconomic status and PA. </span></p><p><span class="fontstyle0"><strong>Results</strong>: </span><span class="fontstyle2">The InS IPAQ‑LF demonstrated good test‑retest reliability for total PA (Intraclass correlation coefficient [ICC] =0.79, 95% CI 0.65 to 0.82),<br />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.<br /></span></p><p><span class="fontstyle0"><strong>Conclusions</strong>: </span><span class="fontstyle2">The InS IPAQ‑LF demonstrated considerate evidence of test‑retest reliability and may be valid for evaluating context specific PA mannerisms of adults in InS.<br /></span></p><p><span class="fontstyle0" style="color: #00652e;"><strong>Keywords</strong>: </span><span class="fontstyle3">Exercise, Indian, International Physical Activity Questionnaire, lifestyle medicine, non‑communicable diseases, physical activity</span></p>http://ijpm.mui.ac.ir/index.php/ijpm/article/view/2248http://ijpm.mui.ac.ir/index.php/ijpm/article/download/2248/717718079
