Effect of a common missense variant in LIPA gene on fatty liver disease and lipid phenotype: New perspectives from a single‐center observational study

ObjectiveNon-alcoholic fatty liver disease (NAFLD) is the leading cause of end-stage liver diseases worldwide. Understanding NAFLD prevalence and trends over time at the global, regional and national levels is critical to understanding the NAFLD disease burden and creating more tailored prevention strategies.DesignPopulation-based observational study.SettingThe study was global, including 21 regions and 195 countries or territories.Main outcomes measureThe estimated annual percentage change for NAFLD prevalence.ResultsWorldwide, cases of NAFLD have increased from 391.2 million in 1990 to 882.1 million in 2017, with the prevalence rate increasing from 8.2% to 10.9% during the same period. The increasing trends were consistent across sexes. Case numbers were highest in East Asia, followed by South Asia, then North Africa and the Middle East. The highest prevalence of NAFLD was observed in North Africa and the Middle East, while the greatest increase was detected in Western Europe, followed by Tropical Latin America, then high-income North America.ConclusionNearly all countries or territories worldwide have experienced a significant increase in NAFLD prevalence. The greatest increase was observed in Oman. Almost all countries showed a significant increasing trend in NAFLD prevalence over the past three decades. This drastic increase is alarming and suggests that NAFLD has emerged as a new public health concern worldwide. As such, more efficient prevention strategies are urgently needed.

Abstract Background and Purpose Non-alcoholic fatty liver disease (NAFLD) is becoming the most common liver disease in China. However, the understanding of NAFLD prevalence among Chinese mental disorder inpatients remains insufficient. We aim to investigate the prevalence of NAFLD among mental disorder inpatients in Beijing, China. Methods In this observational study, we included 66,273 mental disorder inpatients between 2014 and 2018, including inpatients with schizophrenia, bipolar disorder, depressive disorder and other mental disorders. Data were obtained from electronic health records of 19 specialized psychiatric hospitals in Beijing. NAFLD was defined by ICD-10 code, excluding other causes of liver disease. We calculated the overall and annual prevalence rates of NAFLD from 2014 to 2018, and compared NAFLD prevalence between sexes, age groups, mental disorders types, antipsychotics use, and comorbidities. Multivariable logistic regression was used to examine risk factors associated with NAFLD. Subgroup analysis was performed in different mental disorder types. Results The prevalence of NAFLD was 17.63% (95% CI 17.34–17.92%) in mental disorder inpatients, increasing from 16.88% in 2014 to 19.07% in 2018. The NAFLD prevalence in participants with schizophrenia (22.44%) was higher than that in participants with bipolar disorder (17.89%), depressive disorder (12.62%), and other mental disorders (12.99%). Women had similar or even higher NAFLD prevalence than men after 50 years. Men, 50–59 years (aOR = 1.71), schizophrenia (aOR = 1.56), bipolar disorder (aOR = 1.47), antipsychotics use (aOR = 1.46), hypertension (aOR = 1.50), diabetes (aOR = 1.83), dyslipidemia (aOR = 2.50) were risk factors for NAFLD in mental disorder inpatients. Conclusion NAFLD was common among Chinese mental disorder inpatients, and increased over years. The prevalence of NAFLD was higher among men, old women, inpatients with schizophrenia, bipolar disorder, antipsychotics, hypertension, diabetes, and dyslipidemia. Fatty liver disease among mental disorder population warrants the attention of psychiatric specialists and health policy-makers.
