Abstract
Background: Data on the alcoholic fatty liver (AFL) is limited. Therefore, we investigated alcohol use and AFL patterns among urban, adult Sri Lankans.
Methods: The study population (selected by age-stratified random sampling) was screened in 2007 (35-64 years) and re-evaluated in 2014. They were assessed by structured interviews, anthropometric measurements, liver-ultrasound, and biochemical and serological tests. AFL was diagnosed on ultrasound criteria, 'unsafe' alcohol consumption (Asian standards: males>14units, females>7units per week) and absence of hepatitis B/C markers. Controls were unsafe alcohol consumers who had no fatty liver on ultrasound.
Results: 2985/3012 (99%) had complete data for analysis. 272/2985 (9.1%) were unsafe-drinkers in 2007 [males-270; mean-age-51.9, SD-8.0 years]. 86/272 (31.6%) had AFL [males-85; mean-age-50.2, SD-8.6 years]. Males [p<0.001], increased waist circumference (WC) [OR 4.9, p<0.01] and BMI>23kg/m2 [OR 3.5, p<0.01] and raised alanine aminotransferase (ALT) [OR 2.8, p<0.01] were independently associated with AFL. 173/272 (63.6%) unsafe alcohol consumers from 2007 were re-evaluated in 2014. 134/173 had either had AFL or had changed to 'safe' or no alcohol consumption. 21/39 (53.8%) [males-21 (100%), mean-age-57.9, SD-7.9 years] who remained 'unsafe' alcohol users who had no fatty liver in 2007 developed AFL after 7-years (annual incidence 7.7%). On bivariate analysis, only males were associated with new-onset AFL. Of the 42 who had AFL at baseline but changed their drinking status from unsafe to safe or no alcohol, 6 had resolution of fatty liver in 2014.
Conclusion: In conclusion, in this community-based study among urban Sri Lankan adults, the annual incidence of AFL among unsafe alcohol users was 7.7%. Furthermore, new-onset AFL was associated with males.
期刊介绍:
The Ceylon Medical Journal, is the oldest surviving medical journal in Australasia. It is the only medical journal in Sri Lanka that is listed in the Index Medicus. The CMJ started life way back in 1887 as the organ of the Ceylon Branch of the British Medical Association. Except for a brief period between 1893 and 1904 when it ceased publication, the CMJ or its forbear, the Journal of the Ceylon Branch of the British Medical Association, has been published without interruption up to now. The journal"s name changed to the CMJ in 1954.
