Abstract
The public health problems in the new millennium are largely related to lifestyle. The illness industry has seen a large growth in the United States with health care expenditure accounting for 14% of the gross national product. The field of behavioral medicine seeks to include individual responsibility in the prevention of chronic disease. There are great possibilities for lifestyle change through behavioral interventions. This manuscript outlines various applications of behavioral techniques and interventions utilized for smoking and obesity. Prevention paradigms and implications for social workers are also outlined.
