**1. Introduction**

Healthy life is the most significant virtue of one's existence. The physical, social, and economical productivity of an individual depends mostly on the quality of life led by an individual. Human beings have always strived to achieve an optimum milieu of internal and external environment [1]. The diseases affecting mankind can be broadly classified into two types—communicable and noncommunicable diseases. With improvement in health-care facilities, sanitation, litigation services, and treatment modalities, the reign of communicable diseases is on a decline. However, a contrary rise of noncommunicable diseases (NCDs) has been observed primarily due to changing lifestyles and diet [2].

The changing scenario favoring NCDs can primarily be contributed to sedentary lifestyle and rapid population aging especially in developing countries like India. Diseases like cardiac problems, cancers, diabetes, psychiatric disorders, and chronic respiratory diseases have seen an exponential increase in recent times and have become the leading causes of death globally killing more people each year than all other causes combined [2, 3]. As per the Global Burden of Disease Study for 1990, noncommunicable diseases ranked first as the cause of death in developed countries as well as in many developing countries and the world as a whole. Hence, common

risk factor approach addressing the problems and issues connected with noncommunicable diseases can influence the major health gains worldwide [3, 4].
