Roma people constitute one of the oldest and largest minorities in Europe. In Slovakia, there are approximately 400,000 Roma, and represent 7.5% of total population (1). However, according to recent official census in 2010, only 105,738 (2% of total population) citizens declared themselves as Roma ethnic. Approximately one sixth of Roma people live in segregated settlements (1). This supplement contains results of the HepaMeta study, which has aimed to map the socioeconomic, lifestyle, selected anthropometric, and health-related aspects of young Roma people living in the settlements and their majority counterparts. This study was conducted in 2011 and its main goal was to explore the prevalence of hepatitis B and C and metabolic syndrome. A group of 452 Roma aged 18-55 years, living in settlements (mean age = 34.7; 35.2% men) was compared to a control group of 403 non-Roma randomly chosen (mean age = 33.5; 45.9% men) from the patient database of collaborating general practitioners. Data were obtained by questionnaire, anthropometric measures and analysed blood and urine samples (2). Roma population from segregated settlements live in significantly worse socioeconomic conditions compared to the majority, they have significantly worse education and higher unemployment rate. More than 80% of Roma have only basal education, higher education was attained by only 2.3% of this group compared to the majority population in which almost 80% completed higher education. More than 90% of Roma people are unemployed. Unemployment rate in the majority population in the studied East Slovakia region is approximately 25%. Two thirds of Roma people, but only 7.2% of the majority population receive social allowances. Approximately two thirds of Roma and one in 25 persons of the majority population cannot pay collection orders and current expenditures. Significant differences have been also found in the standard of living. Just half of Roma people have a stable water supply, toilet, bathroom or shower, whereas in the majority these utilities are available up to 95% of persons. One sixth of Roma people have no electricity (3). Significant differences were also demonstrated in the lifestyle of these groups. Roma men and women have less physical activity (sports, dance, walking) compared to the majority. On the other hand, higher physical activity associated with household was documented in Roma women, which is probably associated with higher number of children in Roma families. Roma people smoke cigarettes more often and are heavy smokers compared to the majority population. Alcohol use among Roma men was comparable to non-Roma men, but Roma women reported lower use of alcohol compared to the majority (4). People from segregated Roma settlements also reported unhealthy diet. They reported eating less fruits, vegetables and dairy products. Roma women reported higher consumption of meat and soft drinks. These differences in eating habits could be associated with higher prevalence of metabolic syndrome in younger age (5). Several significa...
