Differences in survival and cause-specific mortality in a culturally diverse Greek population, 1999-2008

Factors that influence the health status of immigrants living in Greece

Aim

To examine the health status of immigrants living in Greece and investigate the factors that influence it.

Methodology

A cross-sectional study with 1152 immigrants (response rate = 60%) was conducted during April 2013 to March 2014. Regarding the sampling method, as there is no accurate census of immigrants in Greece the snowball sampling was used. Data collection included demographic characteristics, health status, medication and self-reported preventive health examinations of immigrants (blood count, blood pressure, cholesterol, and blood sugar measurement).

Results

The majority of immigrants originated from Albania (51.4%), while 52.6% were males with mean age 37.6 years. Of those 63.5% were working, 80.9% had legal documents for living and working in Greece and 58.2% had valid health and social security. Most of the immigrants (66.6%) considered their health as good/very good. Immigrants without health insurance, lower monthly family income and worst self-reported health did not adhere with their medication treatment due to cost. Immigrants with legal documents and health insurance performed more often blood count measurement, blood pressure measurement, cholesterol measurement and blood sugar measurement. Increased monthly family income was also associated with higher probability of blood count measurement. Very poor/poor/average self-reported health and increased age were associated with higher probability of taking medicines for chronic diseases.

Conclusions

Self-reported health of immigrants in Greece is good/very good while absence of health insurance and legal documents, lower income and worst self-reported health are associated with worst health outcomes.

Design and Development of a Viral Hepatitis and HIV Infection Screening Program (Hprolipsis) for the General, Greek Roma, and Migrant Populations of Greece: Protocol for Three Cross-Sectional Health Examination Surveys

BACKGROUND

Although infectious diseases are globally on the decline, they remain a major global public health problem. Among them, the hepatitis B virus (HBV) or hepatitis C virus (HCV) and HIV infection are of primary interest. Valid prevalence data on these infections are sparse in Greece, especially for vulnerable populations.

OBJECTIVE

This study aimed to present the design and methods of Hprolipsis, an integrated viral hepatitis and HIV screening program administered to adults (≥18 years) from the general, Greek Roma, and migrant populations. Its aims were to estimate the prevalence of HBV, HCV, and HIV; assess infectious disease knowledge level; design, implement, and assess population-specific awareness actions; and offer individual counseling and referral when indicated and HBV vaccination to susceptible Roma and migrants.

METHODS

Multistage, stratified, random sampling based on the 2011 Census was applied to select the general population sample, and nonprobability multistage quota sampling was used for Roma and migrant sample selection. Trained personnel made home (general population) or community (Roma and migrants) visits. Collected blood samples were tested for Hepatitis B surface Antigen, Hepatitis B core Antibody, Hepatitis B surface Antibody, Hepatitis C Antibody, and HIV 1,2 Antibody. The surveys were conducted during May 2013 and June 2016. To estimate an HCV prevalence of 1.5% with 0.3 precision, the required general population sample size was estimated to be 6000. As migrants constitute 10% of the whole Greek population, the migrant sample size was set to 600. A feasible sample size of 500 Greek Roma was set.

RESULTS

In total, 6006 individuals from the general population (response rate 72%), 534 Greek Roma, and 612 migrants were recruited. Blood test results are available for 4245 individuals from the general population, 523 Roma, and 537 migrants.

CONCLUSIONS

Hprolipsis is the first nationwide survey on HBV, HCV, and HIV. Its results will enhance our understanding of the health needs and disease burden of these diseases in the 3 studied populations. Its implementation provided useful recommendations for future studies, particularly in vulnerable populations.

Predictors of Sleep Duration and Sleep Disturbance in Children of a Culturally Diverse Region in North-Eastern Greece

Background Aim: The aim of this study was to examine the sleep characteristics of children and explore associations with various socio-demographic factors in an area of Greece characterized by cultural diversity. Methods: A questionnaire about children's sleep habits had been distributed to parents of children who visited the pediatric outpatient clinic of University General Hospital of Alexandroupolis for a medical examination and to get a health certificate for participation in sports activities. Children with chronic health conditions were excluded. Results: In the study, 449 children (27.1% belonging to minorities) were included, aged 7.6 ± 2.9 years. Most of them (81.7%) slept after 10 p.m., with a mean nocturnal sleep duration of 9.4 ± 1.2 h. The most commonly reported disturbance was snoring (26.2%). Age and high educational level of the mother were both important determinants for sleeping late [OR 1.139 (1.033-1.255); p = 0.009 and OR 1.086 (1.004-1.175); p = 0.040, respectively]. The latter was also associated with an absence of any reported sleep disorder in children [OR 0.934 (0.877-0.994); p = 0.031]. A longer sleep duration was reported among Roma children (p = 0.022), which was more overt in girls (mean sleep duration 10.4 ± 1.6 h). In the Roma group also, the prevalence of sleep disorders was higher. Conclusion: Age progression and maternal educational level, along with cultural background, seem to be correlated with variations in the sleep characteristics of children in a culturally diverse population in Greece.

Is the Definition of Roma an Important Matter? The Parallel Application of Self and External Classification of Ethnicity in a Population-Based Health Interview Survey

The Roma population is typified by a poor and, due to difficulties in ethnicity assessment, poorly documented health status. We aimed to compare the usefulness of self-reporting and observer-reporting in Roma classification for surveys investigating differences between Roma and non-Roma populations. Both self-reporting and observer-reporting of Roma ethnicity were applied in a population-based health interview survey. A questionnaire was completed by 1849 people aged 18–64 years; this questionnaire provided information on 52 indicators (morbidity, functionality, lifestyle, social capital, accidents, healthcare use) indicators. Multivariate logistic regression models controlling for age, sex, education and employment were used to produce indicators for differences between the self-reported Roma (N = 124) and non-Roma (N = 1725) populations, as well as between observer-reported Roma (N = 179) and non-Roma populations (N = 1670). Differences between interviewer-reported and self-reported individuals of Roma ethnicity in statistical inferences were observed for only seven indicators. The self-reporting approach was more sensitive for two indicators, and the observer-reported assessment for five indicators. Based on our results, the self-reported identity can be considered as a useful approach, and the application of observer-reporting cannot considerably increase the usefulness of a survey, because the differences between Roma and non-Roma individuals are much bigger than the differences between indicators produced by self-reported or observer-reported data on individuals of Roma ethnicity.

Caries prevalence and manganese and iron levels of drinking water in school children living in a rural/semi-urban region of North-Eastern Greece

OBJECTIVE

The aim of this study was to correlate different combinations of manganese (Mn) and iron (Fe) concentration in drinking water with prevalence of dental caries in both primary and permanent dentition, among school children with similar socio-demographic characteristics.

METHODS

Evros region, in North-Eastern Greece, was divided into four areas, according to combinations of levels of Mn and Fe in drinking water (High Mn-high Fe; High Mn-low Fe; Low Mn-high Fe; Low Mn-low Fe). Children of similar socio-economic background, attending either first or sixth grade (primary or permanent dentition, respectively) of elementary schools, were clinically assessed for caries by three dentists. Caries was defined by the use of dmft/DMFT index. A questionnaire answered by the parents was also analysed.

RESULTS

573 children were included. Caries prevalence was high in both age groups (64.2 % with mean dmft 3.3 ± 3.6 in primary and 60.7 % with mean DMFT 2.3 ± 2.5 in permanent dentition, respectively). Residence in a high Mn-low Fe area was associated with a significant OR for caries in both age groups [OR (95 % CIs) for primary and permanent dentition was, respectively, 3.75 (1.68-8.37), p = 0.001 and 3.09 (1.48-6.44), p = 0.003], independently of factors like sugar consumption or brushing frequency.

CONCLUSION

Prevalence of caries was high in general, and was associated with the combination of high Mn/low Fe levels in drinking water, independently of various socio-demographic factors.
