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.
识别男性和女性对运动益处和障碍的感知差异，并确定卡拉奇成年居民的运动水平（PA）的性别和年龄差异。
在 2010 年 7 月至 10 月期间进行了横断面调查，共纳入 300 名成年个体。通过问卷测量运动益处和障碍的感知以及 PA 水平。根据年龄和性别分层计算运动益处和障碍感知以及 PA 水平的差异。
女性比男性感知到更多的运动障碍（P 值<0.001）。在所有年龄层，女性的家务相关体力活动排名较高，而男性的工作相关 PA 排名较高。在所有年龄组中，女性的休闲时间 PA 明显较低。总 PA 也受到年龄和社会经济地位的影响，收入低于 6000 卢比的人群中较高，而 45 岁以上的男性则较低。
在巴基斯坦大都市，存在基于性别的 PA 水平和运动感知差异。需要设计影响与性别相关的 PA 决定因素的方案，以预防即将到来的非传染性疾病流行。
