The current definition of health of the World Health Organization (WHO), formulated in 1948, describes health as “a state of complete physical, mental and social well-being and not simply the absence of disease or infirmity”.[1] Although, this formulation was been revolutionary because it overcame the negative definition of health as the absence of disease and included physical, mental and social domains, it has been partially criticized over the past 60 years. This definition is in fact referred to the disease acute pattern, which is transient and limited in the time. Today, the number of people living with chronic diseases for decades is increasing worldwide.
