Obesity is a serious public health problem of 21st century not only in adults but also among children and adolescents and is an important cause of morbidity and mortality. Obesity in early years of life increases the risk of obesity in later life with a higher risk of developing type-2 diabetes, hypertension, metabolic syndrome, arthritis and cardiovascular diseases.
Obesity is a multifactorial and heterogeneous disease due to complex interaction of genetic and environmental factors. Studies involving genetic and molecular analysis of obesity have identified major genes involved in the regulation of energy expenditure and energy intake. Interaction of many genetic variants with one another and with environment predisposes to weight gain and obesity.
Obesity represents a major epidemic throughout the world as its prevalence is increasing both in developed and developing countries of the world. The rising prevalence of obesity is an issue of great concern in children due to adverse health problems associated with it and need to be addressed at molecular and cellular level.
