The aim of this study was to describe the detailed physical activity profiles of educated, employed, urban Indians and to ascertain their knowledge about the benefits of exercise, their concept of 'ideal' exercise, and the constraints in achieving it. To this end, 401 subjects (193 males, 208 females) between the ages of 25 and 58 years were studied. Women were significantly more active than men (p < 0.05), largely due to enhanced household activity (p < 0.05), which was not offset by the higher leisure time-related exercise of males (p < 0.05). Over 50 percent of subjects were aware of the benefits of exercise in preventing heart disease. The subjects' perceptions of 'ideal' exercise, based on exercise programmes they had drawn up for themselves, were adequate in terms of frequency and duration, but inadequate in intensity, when compared with the current recommendations for exercise in primary prevention of coronary heart disease. Lack of time (men 53.4%, women 68.3%) and lack of motivation (men 26.4%, women 28.4%) were the most-often cited reasons for being unable to achieve 'ideal' exercise goals. The data provides an important framework for understanding physical activity profiles of urban, educated and employed Indians on the basis of which behavioural strategies can be formulated to enhance physical activity and reduce cardiovascular risk.
本研究旨在描述受过教育、有工作的城市印度人的详细身体活动状况，并确定他们对运动益处的了解、他们的“理想”运动概念以及实现该理想运动的制约因素。为此，对401名年龄在25至58岁之间的受试者（193名男性，208名女性）进行了研究。女性的身体活动明显多于男性（p < 0.05），这主要是由于家务活动增加（p < 0.05），而男性与休闲时间相关的运动量较高并不能抵消这一差异（p < 0.05）。超过50%的受试者了解运动对预防心脏病的益处。根据受试者为自己制定的运动计划，他们对“理想”运动的认知在频率和时长方面是足够的，但与目前冠心病一级预防中的运动建议相比，强度方面则不够。没时间（男性53.4%，女性68.3%）和缺乏动力（男性26.4%，女性28.4%）是最常被提及的无法实现“理想”运动目标的原因。这些数据为了解城市、受过教育且有工作的印度人的身体活动状况提供了一个重要框架，在此基础上可以制定行为策略，以增加身体活动并降低心血管疾病风险。
