Introductory lecture the epidemiology and determinants of obesity in developed and developing countries.

摘要

Obesity is recognized as a serious problem in the industrialized and developed countries of the world. However, little attention is paid to the fact that obesity is becoming an increasing problem in developing countries too, with some countries showing increasing rates of obesity in the midst of the persisting occurrence of childhood malnutrition and stunting. As developing countries embrace the dominant western economic ways of development, industrialization and urbanization they contribute to improvements in living standards, with consequent dramatic changes in diets and lifestyles leading to weight gain and obesity which in turn poses a growing threat to the health. Overweight and obesity is associated with an increased likelihood of non-insulin dependent diabetes mellitus, hypertension, hyper-lipidaemia, and cardiovascular disease. It is also associated with increased rates of breast, colo-rectal and uterine cancer. Obesity is thus an important factor in the increasing morbidity and mortality due to chronic, non-communicable diseases (NCDs) and thereby contributes to premature mortality in the population. Thus, while the problem of undernutrition persists in much of the developing world, overweight and obesity and its related co-morbidities are posing an increasingly important public health problem both in the developed and developing world.
