Point-of-care tools to assess advanced liver fibrosis, including the NFS, BARD, FIB-4, and APRI, are of major interest due to their noninvasive nature. However, these tools have not been investigated extensively in the Latina population. Given that the highest rate of NAFLD in Latinos and the most severe presentation of non-alcoholic fatty liver disease (NAFLD) is more common in women, we hypothesize that ethnicity may play a role in predicting liver fibrosis, particularly in women. We determined whether ethnicity alone or in association with other parameters can predict the severity of fibrosis in women with NAFLD when included in four tools. We retrospectively included 562 Latina and 133 White Caucasian women with a history of NAFLD. Associations between ethnicity and liver fibrosis severity using the four fibrosis predictor models were studied using backward selection multinomial logistic regression. Latina women compared to White showed lower body mass index (p < 0.001), higher HbA1c (p < 0.001), lower prevalence of bariatric surgery (p < 0.001), lower likelihood to smoke (p = 0.003), and higher prevalence of chronic kidney disease stages 3-5 (p = 0.01). Some clinical variables were associated with fibrosis but not univocally in each tool. We did not find differences in the outcome of the four models when holding all other factors and examining ethnicity alone between Latina and White women. Although we did not include data on liver histology, this is the first study examining the role of ethnicity in predicting the severity of fibrosis using established noninvasive scores and documenting no association between Latina ethnicity and the severity of fibrosis in women with NAFLD.

Nonalcoholic fatty liver disease (NAFLD) has become the most common form of chronic liver disease in the USA. Interestingly, most patients with NAFLD are unaware of having any liver disease (LD). We aimed to assess the awareness of suspected NAFLD and factors associated with being aware of LD.
Adult subjects with suspected NAFLD (BMI > 25) with elevated ALT in the absence of secondary causes of LD who participated in the continuous national health and nutrition examination survey (NHANES) during 2001-2016 were identified and analyzed. Trends of NAFLD awareness were then assessed in periods of 4 years each. Multivariable logistic regression analysis was performed to assess factors associated with LD awareness.
A total of 7033 subjects were included in the final analysis (1731, 1757, 1711, and 1834 subjects for the periods of 2001-2004, 2005-2008, 2009-2012, and 2013-2016, respectively). Over the study duration, an increase in BMI, waist circumference, diabetes, and HbA1c; and a decrease in the number of smokers, platelets count, bilirubin, total cholesterol, and LDL level were noticed (p < 0.001). Awareness of having LD across study periods has increased over time from 1.5% in the 2001-2004 periods to 3.1% in the 2013-2016 periods. Multivariable logistic regression analysis showed that older age, ethnicity (non-black), having fewer drinks/week, metabolic syndrome, higher ALT, ALP, and GGT were associated with being aware of having LD.
Awareness of having LD among subjects with suspected NAFLD has increased over the last two decades, but more than 95% of these patients are still unaware of having LD. Educational programs to increase awareness of LD and risk factors for NAFLD should be implemented on a large scale.
