Abstract
To identify sex-based differences in the perception of benefits and barriers toward exercise and to determine the sex- and age-based differences in the level of physical activity (PA) among adult residents of Karachi.
Three hundred adult individuals were included in cross sectional survey conducted during July-October 2010. Perception of benefits and barriers to exercise and the level of PA were measured through a questionnaire. Differences in the perception of benefits and barriers of exercise and level of PA were calculated with age and sex strata.
Women perceived more barriers to exercise than men (P-value < 0.001). In all age strata women have higher ranks for domestic-related physical activity while men have higher ranks for job-related PA. Leisure time PA were significantly lower for females in all age groups. Total PA is also affected by age and socioeconomic status, higher among people having monthly income < 6000 rupees and lower in males > 45 years of age.
Sex-based differences exists in the level of PA and perception regarding exercise in mega city of Pakistan. There is a need to design programs that influence PA determinants connected to sex to prevent impending epidemic of non communicable diseases.
