Non-alcoholic fatty liver disease (NAFLD) is considered the liver manifestation of metabolic syndrome. Nowadays, its prevalence is 25% worldwide and it is projected to reach the 30% in 2030, making NAFLD an important public health issue. NAFLD prevalence can vary according to the region and the social group under study. In fact, NAFLD distribution shows large inequalities by social group: Males have higher NAFLD prevalence, although if only postmenopausal women are taken into account, the prevalence is similar between genders. In the US, the Hispanic population has the highest NAFLD prevalence and African-American the lowest. Finally, higher NAFLD prevalence has been found among individuals with lower socioeconomic positions and food-insecure households.
Non-alcoholic fatty liver disease (NAFLD) is considered the liver manifestation of metabolic syndrome . Nowadays NAFLD worldwide prevalence is 25% , although its distribution can differ according to the region and the social group under study. Overall, Europe has an average NAFLD prevalence of 23.5%, in the US is estimated to be 24.5%; in South America, a 30.45% ; Asia a 25% of prevalence , and Africa an estimated prevalence of a 13% .
As well as other metabolic diseases, such as obesity and diabetes, NAFLD prevalence is progressively increasing: it is projected to reach 30% of prevalence among the adult population in 2030 . The increasing prevalence, as well as the derived clinical and economic burden, makes the NAFLD an important public health issue that needs to be addressed through the development of accurate diagnostics, effective treatments, and the implementation of preventive methods for high NAFLD risk individuals .
