Important progress has been made in the past few years concerning the Obesity which is a leading preventable cause of death worldwide, with increasing prevalence in adults and children, and authorities view it as one of the most serious public health problems of the 21st century. The economic, social, and cultural factors that influence the distribution of body mass index in a population are the topics studied here. Future research needs Public health research aimed at defining realistic goals and strategies to improve health in an environment conducive to high levels of overweight and obesity. Overweight children are more likely to have cardiovascular and digestive diseases in adulthood as compared with those who are lean. Consequently, both over-consumption of calories and reduced physical activity are involved in childhood obesity. Prevention may include primary prevention of overweight or obesity, secondary prevention or prevention of weight regains following weight loss, and avoidance of more weight increase in obese persons unable to lose weight. Prevention may be achieved through a variety of interventions targeting built environment, physical activity, and diet. Some of these potential strategies for intervention in children can be implemented by targeting preschool institutions, schools or after-school care services as natural setting for influencing the diet and physical activity. All in all, there is an urgent need to initiate prevention and treatment of obesity in children.
