Core Tip
Core tip: The influence of the economy on the prevalence of fatty liver disease (FLD) is unclear, especially in China, which was the world’s fastest-growing major economy. In this study, a systematic review of population-based surveys was performed to explore the adult prevalence of FLD in mainland China. The gross domestic product per capita was chosen as an indicator to evaluate local economic status. Our analysis indicated that the mean prevalence of FLD in China was 16.73% and that the prevalence increased as China’s economy developed over the past 20 years. In addition, the prevalence over the next 7 years was estimated based on the current trend.
