Abstrakt
The prevalence of obesity is increasing worldwide, and obesity represents one of the major health hazards (1). Obesity was shown to be linked to an increased mortality and morbidity.
However, obesity is often associated with modifications of physical activity level. Physical activity level itself affects the health status of the individual and thus may be a confounding variable in the obesity-mortality/morbidity relationship.
Understanding the role of physical activity in the development of obesity-associated health hazards appears crucial for effective treatment of obesity and prevention of its complications.
