Non-alcoholic fatty liver disease (NAFLD) affects 20–25% of the general population and is associated with morbidity, increased mortality, and elevated health-care costs. Most NAFLD risk factors are modifiable and, therefore, potentially amenable to being reduced by public health policies. To date, there is no information about NAFLD-related public health policies in the Americas. In this study, we analysed data from 17 American countries and found that none have established national public health policies to decrease NAFLD-related burden. There is notable heterogeneity in the existence of public health policies to prevent NAFLD-related conditions. The most common public health policies were related to diabetes (15 [88%] countries), hypertension (14 [82%] countries), cardiovascular diseases (14 [82%] countries), obesity (nine [53%] countries), and dyslipidaemia (six [35%] of countries). Only seven (41%) countries had a registry of the burden of NAFLD, and efforts to raise awareness in the Americas were scarce. The implementation of public health policies are urgently needed in the Americas to decrease the burden of NAFLD.

非酒精性脂肪性肝病 (NAFLD) 影响 20-25% 的普通人群，并与发病率、死亡率增加和医疗保健费用增加有关。大多数 NAFLD 风险因素是可以改变的，因此可能会被公共卫生政策降低。迄今为止，没有关于美洲与 NAFLD 相关的公共卫生政策的信息。在这项研究中，我们分析了来自 17 个美国国家的数据，发现没有一个国家制定了国家公共卫生政策来减少与 NAFLD 相关的负担。预防 NAFLD 相关疾病的公共卫生政策存在显着的异质性。最常见的公共卫生政策与糖尿病（15 [88%] 个国家）、高血压（14 [82%] 个国家）、心血管疾病（14 个 [82%] 个国家）、肥胖（9 个 [53%] 个国家）、和血脂异常（6 个 [35%] 的国家）。只有七个 (41%) 国家登记了 NAFLD 的负担，在美洲提高认识的努力很少。美洲迫切需要实施公共卫生政策以减轻 NAFLD 的负担。
