Hypertension and obesity are two closely related pathologies in clinical practice. Currently, about one billion adults worldwide are overweight, and it is estimated that, if no serious action is taken to effect profound change, that figure will continue to rise throughout this century. Hypertension is also a serious public health problem worldwide, one that, along with type 2 diabetes, is growing due to increases in both life expectancy and obesity. However, the rate of increase varies by population group. For example, in the United States, the prevalence of obesity differs quite markedly among the white population of European origin, African American individuals, and the Latin American population. This disparity exists among other populations as well, such as that of Argentina, where obesity is less prevalent than in the United States. This significant difference between the Argentinean population and that of American whites may be explained by the former population's migratory origin and distinct eating habits.
