**Abstract**

This chapter focuses on the study designed to assess the role of lifestyle in the development of coronary heart disease (CHD). The data were analyzed to compare the patients of CHD with matched normal. Lifestyle is defined as the general behaviour pattern of an individual including health behaviour, job involvement and work style, social interactions, intimacy, locus of control and values. For this purpose the matching of patients was carried out on one to one basis and on the parameters of the age, education, family size and socioeconomic status. Total sample size was 162. To measure lifestyle, a structured interview schedule was prepared which included questions on the subparts, viz. health behaviour pattern, job involvement and work style, social interactions, intimacy, locus of control, values. The coding of the responses was quantified. The higher is the scores more is the risky lifestyle whereas lower scores indicate the healthy lifestyle. Qualitative and quantitative analysis were carried out.
