Age trends in prevalence of cardiovascular risk factors in Roma minority population of Croatia

Explaining adverse cholesterol levels and distinct gender patterns in an Indonesian population compared with the U.S

Cardiovascular disease is among the most common causes of death around the world. As rising incomes in low and middle-income countries are accompanied by increased obesity, the burden of disease shifts towards non-communicable diseases, and lower-income settings make up a growing share of cardiovascular disease deaths. Comparative investigation of the roles of body composition, behavioral and socioeconomic factors across countries can shed light on both the biological and social drivers of cardiovascular disease more broadly. Comparing rigorously-validated measures of HDL and non-HDL cholesterol among adults in the United States and in Aceh, Indonesia, we show that Indonesians present with adverse cholesterol biomarkers relative to Americans, despite being younger and having lower body mass index. Adjusting for age, the gaps increase. Body composition, behaviors, demographic and socioeconomic characteristics that affect cholesterol do not explain between-country HDL differences, but do explain non-HDL differences, after accounting for medication use. On average, gender differences are inconsistent across the two countries and persist after controlling observed characteristics. Leveraging the richness of the Indonesian data to draw comparisons of males and females within the same household, the gender gaps among Indonesians are not explained for HDL cholesterol but attenuated substantially for non-HDL cholesterol. This finding suggests that unmeasured household resources play an important role in determining non-HDL cholesterol. More generally, they appear to be affected by social and biological forces in complex ways that differ across countries and potentially operate differently for HDL and non-HDL biomarkers. These results point to the value of rigorous comparative studies to advance understanding of cardiovascular risks across the globe.

Impact of global smoking prevalence on mortality: a study across income groups

BACKGROUND

Smoking significantly contributes to the mortality rates worldwide, particularly in non-communicable and preventable diseases such as cardiovascular ailments, respiratory conditions, stroke, and lung cancer. This study aims to analyse the impact of smoking on global deaths, and its association with mortality across the main income groups.

METHODS

The comprehensive analysis spans 199 countries and territories from 1990 to 2019. The study categorises countries into four income groups: high income, upper middle income, lower middle income, and low income.

RESULTS

The findings underscore the profound impact of global tobacco smoking on mortality. Notably, cardiovascular disease mortality is notably affected in both upper-middle-income and high-income groups. Chronic respiratory disease mortality rates show a significant impact across all income groups. Moreover, stroke-related mortality is observed in the lower-middle, upper-middle, and high-income groups. These results highlight the pervasive influence of smoking prevalence on global mortality, affecting individuals across various socioeconomic levels.

CONCLUSION

The study underscores the critical implications of smoking on mortality rates, particularly in high-income countries. It emphasises the urgency of targeted interventions in these regions to address the specific challenges posed by tobacco smoking on public health. Policy recommendations include implementing prohibitive measures extending to indoor public areas such as workplaces and public transportation services. Furthermore, allocating funds for research on tobacco and health, is imperative to ensure policymakers are consistently informed about emerging facts and trends in this complex domain.

Comparison of Genetic Susceptibility to Coronary Heart Disease in the Hungarian Populations: Risk Prediction Models for Coronary Heart Disease

Background and Aim: It was evaluated whether the integration of genetic risk scores (GRS-unweighted, wGRS-weighted) into conventional risk factor (CRF) models for coronary heart disease or acute myocardial infarction (CHD/AMI) could improve the predictive ability of the models. Methods: Subjects and data collected in a previous survey were used to perform regression and ROC curve analyses as well as to examine the role of genetic components. Thirty SNPs were selected, and genotype and phenotype data were available for 558 participants (general: N = 279 and Roma: N = 279). Results: The mean GRS (27.27 ± 3.43 vs. 26.68 ± 3.51, p = 0.046) and wGRS (3.52 ± 0.68 vs. 3.33 ± 0.62, p = 0.001) were significantly higher in the general population. The addition of the wGRS to the CRF model yielded the strongest improvement in discrimination among Roma (from 0.8616 to 0.8674), while the addition of GRS to the CRF model yielded the strongest improvement in discrimination in the general population (from 0.8149 to 0.8160). In addition to that, the Roma individuals were likely to develop CHD/AMI at a younger age than subjects in the general population. Conclusions: The combination of the CRFs and genetic components improved the model's performance and predicted AMI/CHD better than CRFs alone.

Genetic Determinants of Leisure-Time Physical Activity in the Hungarian General and Roma Populations

Leisure-time physical activity (LTPA) is one of the modifiable lifestyle factors that play an important role in the prevention of non-communicable (especially cardiovascular) diseases. Certain genetic factors predisposing to LTPA have been previously described, but their effects and applicability on different ethnicities are unknown. Our present study aims to investigate the genetic background of LTPA using seven single nucleotide polymorphisms (SNPs) in a sample of 330 individuals from the Hungarian general (HG) and 314 from the Roma population. The LTPA in general and three intensity categories of it (vigorous, moderate, and walking) were examined as binary outcome variables. Allele frequencies were determined, individual correlations of SNPs to LTPA, in general, were determined, and an optimized polygenetic score (oPGS) was created. Our results showed that the allele frequencies of four SNPs differed significantly between the two study groups. The C allele of rs10887741 showed a significant positive correlation with LTPA in general (OR = 1.48, 95% CI: 1.12-1.97; p = 0.006). Three SNPs (rs10887741, rs6022999, and rs7023003) were identified by the process of PGS optimization, whose cumulative effect shows a strong significant positive association with LTPA in general (OR = 1.40, 95% CI: 1.16-1.70; p < 0.001). The oPGS showed a significantly lower value in the Roma population compared with the HG population (oPGS_Roma: 2.19 ± SD: 0.99 vs. oPGS_HG: 2.70 ± SD: 1.06; p < 0.001). In conclusion, the coexistence of genetic factors that encourage leisure-time physical activity shows a more unfavorable picture among Roma, which may indirectly contribute to their poor health status.

The profile of HDL-C subfractions and their association with cardiovascular risk in the Hungarian general and Roma populations

High-density lipoprotein cholesterol (HDL-C) is not a homogenous lipid fraction, but it can be further divided into subfractions. It is well-known that the Roma population has a high prevalence of reduced HDL-C levels and cardiovascular diseases (CVDs). However, it is unknown how this reduction affects different HDL subfractions, and whether changes in their quantity/representation are associated with an increased cardiovascular risk among them. In the present study, the HDL subfraction profile of the Hungarian general (HG) and the Roma populations were compared, and the subfractions showing a significant difference between the two populations were identified. The association of HDL subfractions with CVD risk estimated by the Framingham risk score (FRS) and the Systematic COronary Risk Evaluation (SCORE) algorithms were also defined. The present study is the first to find a significant association between HDL subfractions and cardiovascular risk estimated by FRS and SCORE. Ten HDL subfractions were investigated on small but carefully selected samples comprising 100 control subjects (with normal lipid profile) and 277 case subjects (with reduced HDL-C levels) from HG and Roma populations of a complex health survey. The level of HDL-1 to 3 subfractions and HDL-L showed a significant inverse association with cardiovascular risk estimated by both SCORE and FRS algorithms, whereas HDL-4 to 6 and HDL-I only for FRS. A higher representation (in %) of HDL-1 to 3 has a significant risk-reducing effect, while HDL-8 to 10 has a risk-increasing effect estimated by FRS. Our results confirmed that reduced levels of HDL-6 and -7 expressed in mmol/L were significantly associated with Roma ethnicity.

CVD Risk Factors in the Ukrainian Roma and Meta-Analysis of Their Prevalence in Roma Populations Worldwide

The Roma population suffers from severe poverty, social exclusion, and some of the worst health conditions in the industrialized world. Herein, we report on cardiovascular disease (CVD) risk factors in the Ukrainian Roma and present a meta-analysis of the prevalence of CVD risk factors in 16 Roma populations worldwide. The meta-analyses of CVD risk factors in Roma (n = 16,552) vs. non-Roma majority population of the same country (n = 127,874) included publicly available data. Ukrainian field survey included 339 adults of both sexes and outcomes of interest were hypertension, body mass index (BMI), smoking, education, and employment status. Furthermore, 35.7% of the Ukrainian Roma were hypertensive, 69.3% unemployed, and 48.4% never went to school. Ukrainian Roma women were more likely to be underweight and more prone to be hypertensive, with odds of hypertension increasing with age, BMI, and positive smoking status. Meta-analyses showed that, in comparison with non-Roma worldwide, the Roma bear significantly higher risk factor loads related to smoking (OR = 2.850), diabetes (OR = 1.433), abdominal obesity (OR = 1.276), and metabolic syndrome (OR = 1.975), with lower loads for hypertension (OR = 0.607) and BMI ≥ 25 kg/m² (OR = 0.872). To conclude, the CVD risk factors which are more common in Roma than in the majority population may reflect their poor health-related behaviors and inadequate access to health education.

Prevalence of Insulin Resistance in the Hungarian General and Roma Populations as Defined by Using Data Generated in a Complex Health (Interview and Examination) Survey

Data mainly from one-off surveys clearly show that the health of Roma, the largest ethnic minority of Europe, is much worse than that of the general population. However, results from comprehensive exploratory studies are missing. The aim of our study was to create a complex database for comparative and association studies to better understand the background of the very unfavourable health of Roma, especially the high burden of cardiometabolic diseases. A three-pillar (questionnaire-based, physical and laboratory examinations) health survey was carried out on randomly selected samples of the Hungarian general (HG, n = 417) and Roma (HR, n = 415) populations, and a database consisting of more than half a million datapoints was created. Using selected data, the prevalence rates of metabolic syndrome (MetS) and of its components were determined, and to estimate the risk of insulin resistance (IR), surrogate measures (the homeostasis model assessment of insulin resistance index, quantitative insulin sensitivity check index, McAuley and TyG indices and the TG/HDL-C ratio) were calculated. Receiver operating characteristic curve analysis and Youden’s method were used to define the optimal cut-off values of each IR index. The prevalence of MetS was very high in both study populations (HG: 39.8%, HR: 44.0%) with no statistically significant difference between the two groups in females or males. The prevalence of MetS showed a very marked increase in the HR 35–49 years age group. Among surrogate measures, the TyG index showed the greatest power for predicting IR/MetS at a cut-off value of 4.69 (77% sensitivity, 84% specificity) and indicated a 42.3% (HG) and 40.5% (HR) prevalence of IR. The prevalence of MetS and IR is almost equally very unfavourable in both groups; thus, the factors underlying the high premature mortality burden of Roma should be further clarified by investigating the full spectrum of risk factors available in the database, with a special focus on the access of Roma people to preventive and curative health services.

The genetic risk for hypertension is lower among the Hungarian Roma population compared to the general population

Estimating the prevalence of cardiovascular diseases (CVDs) and risk factors among the Roma population, the largest minority in Europe, and investigating the role of genetic or environmental/behavioral risk factors in CVD development are important issues in countries where they are significant minority. This study was designed to estimate the genetic susceptibility of the Hungarian Roma (HR) population to essential hypertension (EH) and compare it to that of the general (HG) population. Twenty EH associated SNPs (in AGT, FMO3, MTHFR-NPPB, NPPA, NPPA-AS1, AGTR1, ADD1, NPR3-C5orf23, NOS3, CACNB2, PLCE1, ATP2B1, GNB3, CYP1A1-ULK3, UMOD and GNAS-EDN3) were genotyped using DNA samples obtained from HR (N = 1176) and HG population (N = 1178) subjects assembled by cross-sectional studies. Allele frequencies and genetic risk scores (unweighted and weighted genetic risk scores (GRS and wGRS, respectively) were calculated for the study groups and compared to examine the joint effects of the SNPs. The susceptibility alleles were more frequent in the HG population, and both GRS and wGRS were found to be higher in the HG population than in the HR population (GRS: 18.98 ± 3.05 vs. 18.25 ± 2.97, p<0.001; wGRS: 1.52 [IQR: 0.99–2.00] vs. 1.4 [IQR: 0.93–1.89], p<0.01). Twenty-seven percent of subjects in the HR population were in the bottom fifth (GRS ≤ 16) of the risk allele count compared with 21% of those in the HG population. Thirteen percent of people in the HR group were in the top fifth (GRS ≥ 22) of the GRS compared with 21% of those in the HG population (p<0.001), i.e., the distribution of GRS was found to be left-shifted in the HR population compared to the HG population. The Roma population seems to be genetically less susceptible to EH than the general one. These results support preventive efforts to lower the risk of developing hypertension by encouraging a healthy lifestyle.

The Effect of Haplotypes in the CETP and LIPC Genes on the Triglycerides to HDL-C Ratio and Its Components in the Roma and Hungarian General Populations

BACKGROUND

The triglycerides (TG) to high-density lipoprotein (HDL)-cholesterol (HDL-C) ratio (TG/HDL-C) is a well-known predictor for cardiovascular diseases (CVDs) with great heritability background. The cholesteryl ester transfer protein (CETP) and hepatic lipase (LIPC) gene affect TG/HDL-C ratio. This study aims to explore the association between haplotypes (H) in CETP (based on 5 single nucleotide polymorphisms (SNPs)) and LIPC (based on 6 SNPs) genes and the TG/HDL-C ratio and its components, among Roma and Hungarian general populations.

METHODS

The prevalence of haplotypes and their effect on HDL-C, TG and TG/HDL-C ratio were calculated in both populations and compared.

RESULTS

Ten haplotypes in CETP and 6 in LIPC gene were identified. Three haplotypes in CETP and 3 in LIPC have significant effect on HDL-C level, whereas two in CETP and 3 in LIPC on TG level. The H6 in CETP (β = 0.52, p = 0.015; odds ratio (OR) = 1.87, p = 0.009) and H5 in LIPC (β = 0.56, p < 0.001; OR = 1.51, p = 0.002) have a significant increasing effect on TG/HDL-C ratio and have shown higher prevalence among the Roma, as compared to Hungarian general population. The H2 in the CETP gene has a decreasing effect on the TG/HDL-C ratio (OR = 0.58, p = 0.019) and is significantly less frequent among the Roma.

CONCLUSIONS

Accumulation of harmful haplotypes in CETP and LIPC genes might have a role in the elevated TG/HDL-C ratio in the Roma population, which contributes to a higher risk in the development of cardiovascular diseases.

Cardiovascular risk factors in a Roma sample population from Romania

BACKGROUND

The Roma population has a high prevalence of cardiovascular risk factors, higher mortality, and shorter life expectancy. It is found in the largest number in Romania, but published data are still scarce here. We studied cardiovascular risk factors and disease along with target organ damage on a population of Roma inhabitants from Bucharest, Romania.

METHODS

This cross-sectional study enrolled 806 Roma subjects (18-83 years), in a community-based participatory research manner. Demographics included anthropometric data, a questionnaire on social status, education, medical history, and health deleterious behaviors. Medical evaluation included clinical examination, blood pressure, ankle-brachial index, pulse wave velocity measurements, blood tests (complete blood count, lipid profile, glucose, creatinine, uric acid), dip-stick microalbuminuria, dilated fundoscopy, ECG, and echocardiography.

RESULTS

Prevalence of all cardiovascular risk factors was high, peaking in abnormal lipid metabolism (82.13%), heavy smoking (63.02% including ex-smokers) and obesity (50.99%). The first and the latter were actually similar to the general population in Romania. Almost half of subjects were at high or very high risk for fatal cardiovascular disease.

CONCLUSIONS

The study shows that the Roma population in a more affluent region in Romania shares a similarly high cardiovascular burden to their surrounding community.

Prevalence of Diabetes Mellitus among Roma Populations-A Systematic Review

Background: The aim of this study was to estimate the prevalence of diabetes mellitus in the Roma population and compare it to the prevalence in the Caucasian population. Methods: Using the words “Roma”, “Gypsies”, “Romani”, and ”traveler” in combination with “diabetes, “metabolic syndrome”, “cardiovascular disease” and “health status” we searched the MEDLINE, Pubmed and Scopus databases for articles in English that focused on the prevalence of diabetes mellitus among Roma populations published until December 2017. Results: Five studies met the inclusion criteria. The results of four of them suggested a higher prevalence of diabetes among Romani compared to Caucasians but none of them reached the standards regarding representative samples and number of cases for a conclusive result. Conclusion: Although some of the existing studies suggest a substantial prevalence of diabetes among Roma populations and even a higher risk of developing diabetes for Roma persons compared to Caucasians, the number of published literature on this topic remains very low and insufficient in design and number of participants to draw any conclusions.

Genetic factors exist behind the high prevalence of reduced high-density lipoprotein cholesterol levels in the Roma population

BACKGROUND AND AIMS

Previous findings showed that reduced plasma high-density lipoprotein cholesterol (HDL-C) levels are more frequent in all age groups of the Hungarian Roma compared to the general population. It suggests that genetic factors may exist behind this phenomenon. Our present study was designed to test this hypothesis, i.e., to define whether genetic factors contribute to the higher prevalence of reduced HDL-C among Roma. Single nucleotide polymorphisms (N = 21) contributing to the variation in plasma HDL-C concentrations were analysed in the Hungarian Roma (N = 646) and general (N = 1542) populations.

METHODS

Genetic risk scores, unweighted (GRS) and weighted (wGRS), were computed and compared. Associations between the GRSs and the prevalence of reduced HDL-C levels were analysed.

RESULTS

The GRS and wGRS were significantly higher in the Roma compared to the general population (GRS: 22.2 ± 3.2 vs. 21.5 ± 3.3; wGRS: 0.57 ± 0.1 vs. 0.53 ± 0.1; p<0.001). One half per cent of Roma subjects were in the bottom fifth of the wGRS (wGRS≤ 0.3) compared with 1.8% of those in the general population (p=0.025), while 5% of the Roma subjects were in the top fifth of the wGRS (wGRS≥ 0.75) compared with 2.6% of those in the general population (p=0.004). The GRS showed similar correlation with reduced plasma HDL-C levels in the two populations, whilst the wGRS showed stronger correlation with the trait among Roma after controlling for confounders.

CONCLUSIONS

These results strongly suggest that genetic factors contribute to the higher prevalence of reduced HDL-C levels among Roma, so interventions aiming to improve Roma health status need to consider their increased genetic susceptibility.

The health of Romanian Gypsy women in Serbia

Indigenous people are over-represented among the world's disadvantaged; their health is influenced by lack of access to critical resources including health care and by their cultural practices. We report on the health and the health practices of one group of indigenous women, the Roma/Gypsies of northern Serbia who live in poverty, reside in sub-standardized housing in segregated communities, and are poorly educated and stigmatized. We describe the environment in which they live, their health history, and the cultural practices that influence their health and health behaviors, including their sporadic utilization of health services that are provided by the state. We also present evidence supporting that, in the face of adversity, cultural practices, including those related to kinship and social support, can have significant benefits in shaping health status.

Does poorer self-rated health mediate the effect of Roma ethnicity on mortality in patients with coronary artery disease after coronaro-angiography?

OBJECTIVES

The aim of this prospective cohort study was to assess the effect of Roma ethnicity and self-rated health (SRH) on 9-year all-cause mortality in patients with coronary artery disease (CAD) after coronaro-angiography (CAG), and whether SRH mediates the effect of ethnicity.

METHODS

623 patients (103 Roma) were included. We obtained data from medical records and patients interviews. A Cox regression model adjusted for age, gender and education was used to analyze the effect of Roma ethnicity on mortality, as well as potential mediation by SRH.

RESULTS

Roma ethnicity and poor SRH were predictors of increased mortality in patients with CAD, with hazard rates (95 % confidence intervals) 2.34 (1.24; 4.42) and 1.81 (1.02; 3.21). Adding education decreased the size of ethnic differences in mortality. The mediating effect of SRH on the association of ethnicity with mortality was not statistically significant; neither modified ethnicity the effect of SRH.

CONCLUSIONS

Poor SRH does not mediate the higher mortality among Roma patients after CAG even though it indicates an increased risk of mortality. Roma patients with CAD have to be referred for special cardiological care earlier.

Seven years' mortality in Roma and non-Roma patients after coronary angiography

BACKGROUND

Ethnicity is associated with differences in clinical course and outcomes of cardiac disease, often in association with a poorer socioeconomic position. The aim of this study was to compare the mortality after coronary angiography (CAG) of Roma and non-Roma patients matched for education and adjusted for gender and age.

METHODS

In total, 816 patients were included in the study (167 Roma and 649 non-Roma). Data on socio-demographic background, disease history, use of drugs, coronary findings and type of treatment were obtained from medical records. Mortality was assessed up to seven years after CAG. Kaplan-Meier curves of mortality were plotted, and differences between the Roma and non-Roma patients were assessed using log-rank tests, matched for education and adjusted for gender and age.

RESULTS

Mortality after CAG was significantly higher among Roma than non-Roma (log-rank test χ(2) = 7.59, P < 0.01) and remained so after matching for education and adjustment for gender, age, history of previous myocardial infarction and abnormal CAG (hazard ratio: 2.07, 95% confidence interval: 1.13-3.82).

CONCLUSION

Mortality after CAG is higher among Roma, and this is not due to differences in age, gender or education. These results warrant further reconsideration of the management of Roma cardiac patients.

Genetic polymorphisms in promoter and intronic regions of CYP1A2 gene in Roma and Hungarian population samples

The purpose of this study was to determine the interethnic differences of four CYP1A2 drug metabolizing enzyme variants. A total of 404 Roma and 396 Hungarian healthy subjects were genotyped for -163C>A, -729C>T, -2467delT and -3860G>A variants of CYP1A2 by RT-PCR and PCR-RFLP technique. The -3860A and -729T allele were not detectable in Roma samples, while in Hungarian samples were present with 2.02% and 0.25% prevalence, respectively. There was a 1.5-fold difference in presence of homozygous -163AA genotype between Hungarian and Roma samples (49.5% vs. 31.9%, p<0.001). The -163A allele frequency was 68.6% in Hungarians and 56.9% in Romas (p=0.025). The -2467delT allele frequency was 6.81% in Roma group and 5.81% in Hungarians. The most frequent allelic constellation was -3860G/-2467T/-729C/-163A in both populations. In conclusion, Hungarians have markedly elevated chance for rapid metabolism of CYP1A2 substrates, intensified procarcinogen activation and increased risk for cancers.

Prevalence of metabolic syndrome among Roma: a comparative health examination survey in Hungary

OBJECTIVES

The objective of our study was to compare the health status of the Roma people with that of the general population in Hungary.

METHODS

A health examination survey to define the prevalence of metabolic syndrome and its components was performed in a representative random sample (n = 646) of the Roma population aged 20-64 years living in segregated colonies, and data were compared with that obtained in a representative random sample (n = 1819) of the Hungarian population.

RESULTS

The risks for central obesity, hypertension and raised triglyceride level among Roma adults were not different from the Hungarian references, while raised fasting plasma glucose or known type 2 diabetes mellitus (OR = 2.65, 95%CI 1.90-3.69), reduced HDL cholesterol level or treated lipid disorder (OR = 2.15, 95%CI 1.65-2.79) were significantly more frequent in all age groups in the Roma sample. The prevalence of metabolic syndrome (OR = 1.37, 95%CI 1.03-1.83) was also significantly higher among Roma than in the general Hungarian population.

CONCLUSIONS

Besides tackling the socio-economic determinants of the poor health of Roma people, specific public health interventions considering increased genetic susceptibility to metabolic disturbances are needed to improve their health status.

Assessment of clinical biochemical parameters in Roma minority residing in eastern Slovakia compared with the majority population

Roma constitute the largest ethnic minority in Europe and the second largest minority in Slovakia. Their health problems originate mainly from their low socioeconomic status, certain cultural aspects and their health-threatening lifestyle as well as the psycho-social burden arising from poverty and frequent migration. Evaluation of glucose, albumin, triacylglycerol (TAG) and low density lipoprotein cholesterol (LDL-C) concentrations did not reveal any clue about the presumed deteriorated health of the Roma population. Higher proportions of subjects with elevated serum total cholesterol were found in Roma women as compared to both control groups of women (p = 0.027, p = 0.006) and in Roma men as compared to the male control group living in standard conditions. Only the low level of HDL-cholesterol gives a glimpse of their deteriorated health. Significantly lower levels of serum HDL-C were reported in Roma men and women compared to the respondents in both control groups with a p value of p < 0.001. Comparing the ratio of LDL-C/HDL-C yielded significant differences between the number of physiological values in Roma men and men from the control group 1 (p = 0.022) in favour of the control group. When comparing the number of people with physiological values of cholesterols and with worsening TAG parameters at the same time, the increased risk of Roma men compared with men from the control group 1 became evident, with a level of significance of p = 0.023. Evaluation of urine samples pointed to significantly higher concentrations of urinary protein in Roma women compared with women in the control group 1 (p = 0.012).

Obesity and body size perceptions in a Spanish Roma population

BACKGROUND

Roma people are particularly vulnerable to developing overweight and obesity. Self-perception of body image may influence the prevalence of obesity in this ethnic minority.

AIM

The objectives of this study are to estimate the prevalence of obesity, to analyse body size perceptions and preferences and to assess the relationship between body size perceptions and obesity in the Roma population.

SUBJECTS AND METHODS

The analyses were carried out on 372 men, women and children from the Roma population residing in the Greater Bilbao region (Basque Country, Spain). In adults, a standard figural scale was used to analyse body size perceptions and preferences in this ethnic minority.

RESULTS

Overall 51.7% of adult and 24.4% of minor Roma individuals were obese. Both Roma men and women had inaccurate self-perceptions of their body size. Significant differences on body size perceptions were detected based on age, sex, nutritional status and socioeconomic characteristics.

CONCLUSION

This Roma population presents one of the highest rates of obesity worldwide. Although a certain awareness of the correct weight status was appreciated, the inability of Roma individuals to see themselves as overweight or obese may be a significant factor on the high prevalence of obesity in this population.

Revisiting the evidence on health and health care disparities among the Roma: a systematic review 2003-2012

OBJECTIVES

To conduct a systematic review of the epidemiological and health service utilization literature related to the Roma population between 2003 and 2012.

METHODS

Systematic review of empirical research related to Roma health and health care utilization published between 2003 and 2012 identified through electronic databases (PsycInfo, Medline, Google Scholar). Methodological rigor was evaluated using a six-point set of design criteria.

RESULTS

We found evidence for lower self-reported health and significantly higher mortality risk for Roma compared to non-Roma, and greater prevalence of health risk factors for Roma children, including environmental risks, low birth weight, and lower vaccination coverage. Studies of non-communicable and infectious disease remain insufficient to make firm conclusions on disparities. Barriers to care include lack of documentation and affordability of care, though more studies on health care utilization are needed.

CONCLUSIONS

Roma youth and adults are in need of programs that reduce health disparities and their increased mortality risk. Reducing exposure to risk factors such as smoking, obesity, and poor living conditions may be a target for interventions. More intervention studies and rigorous evaluations are needed.
