Abnormal liver tests in a Mediterranean ...( A recent population-based study in a sm...),Health

A recent population-based study in a small town in Southern Italy found that one in eight residents had abnormal liver tests. While alcohol consumption was the most common causative factor, nonalcoholic fatty liver disease (NAFLD) is an increasingly prevalent source of the problem. The study is published in the May 2005 issue of Hepatology, the official journal of the American Association for the Study of Liver Diseases (AASLD).

Chronic liver disease is a serious public health issue in many communities. It can be caused by high alcohol consumption, hepatitis B and C, and nonalcoholic fatty liver disease, a condition associated with obesity, insulin resistance, high cholesterol and the like. The importance of these causative factors varies from one location to another. For example, in the U.S., the majority of altered liver enzymes are related to NAFLD, while in northern Italian populations, much is related to alcohol. Factors leading to liver disease had not been thoroughly studied in Southern Italy, so researchers, led by Gaspare Maria Pendino of Reggio Calabria, assessed the prevalence and etiology of altered liver tests in the general population of Cittanova, a small southern Italian town.

They generated a random sample of residents 12 years or older and screened 1645 participants for abnormal liver values, antigens to hepatitis B and C and alcohol consumption. From each individual, they also gathered socioeconomic data, medical history and body mass index.

More than 12 percent of those screened had abnormal liver values, with prevalence increasing with age. The age-trend was mainly due to chronic HCV infection, which affected 6.5 percent of the study population overall and increased in prevalence with age. More men than women had
