Short-term effects of air pollution on exacerbations of allergic asthma in Uzice region, Serbia.

INTRODUCTION: Many time-series studies have shown a positive association between air pollution and asthma exacerbation. However, till now only one study in Serbia has examined this relationship. AIM: To examine the associations between air pollution and asthma emergency department (ED) visits in the Uzice region, Serbia. MATERIAL AND METHODS: A time-stratified case-crossover design was applied to 424 ED visits for asthma exacerbation that occurred in the Uzice region, Serbia, in 2012-2014. Data about ED visits were routinely collected in the Uzice Health Centre. The daily average concentrations of particulate matter (PM2.5 and PM10), sulphur dioxide (SO2), nitrogen dioxide (NO2), and black carbon (BC) were measured by automatic ambient air quality monitoring stations. Odds ratios and their corresponding 95% confidence intervals were estimated using conditional logistic regression adjusted for the potential confounding influence of weather variables (temperature, humidity and air pressure). RESULTS: Statistically significant associations were observed between ED visits for asthma and 3-day lagged exposure to BC (OR = 3.23; 95% CI: 1.05-9.95), and between ED visits for asthma with coexisting allergic rhinitis and 0-day lag exposure to NO2 (OR = 1.57; 95% CI: 0.94-2.65), 2-day lag exposure to SO2 (OR = 1.97; 95% CI: 1.02-3.80), and 3-day lag exposure to PM10 (OR = 2.38; 95% CI: 1.17-4.84). CONCLUSIONS: Exposure to ambient air pollution in the Uzice region increases the risk of ED visits for asthma, particularly during the heating season.

Dental service utilisation among adults in a European developing country: findings from a national health survey.

BACKGROUND: The objective was to estimate the frequency of visits to a dentist and to assess the impact of determinants on dental care utilisation among adults in the Republic of Srpska (RS), Bosnia and Herzegovina. METHODS: We conducted a cross-sectional study using data from the 2010 National Health Survey performed in the RS. A total of 4,128 adults (≥18 years) were interviewed in their homes. Multivariate logistic regression was used to assess the relationship between demographic characteristics, socio-economic characteristics, health behaviours, self-rated health, self-reported noncommunicable diseases (NCDs) and dental care utilisation. RESULTS: Only 20% of all respondents reported a visit to a dentist in the year preceding the interview. Younger respondents (OR = 0.97), women (OR = 1.30-1.39), urban dwellers (OR = 1.41-1.61), those who were employed (OR = 1.20) and those who self-reported NCDs (OR = 1.32-1.33) more frequently utilised dental services. The opposite was true for those in the low wealth index group (OR = 0.79), persons with a low (OR = 0.31) and middle (OR = 0.48) level of education and people who self-rated their health as average (OR = 0.76-0.80). CONCLUSION: The present study revealed a low frequency of visits to a dentist, especially for preventive oral health care. It also confirmed demographic, socio-economic and health-related differences in dental-care utilisation in RS. To minimise those differences, systemic approaches aimed at increasing access to dental care could be an important step. Oral health-promotion policies need to be adopted in the RS.

Cardiovascular Health Status and Metabolic Syndrome in Adults Living in a Transition European Country: Findings from a Population-Based Study.

BACKGROUND AND PURPOSE: There are only a few published studies on the relationship between cardiovascular health (CVH) status as proposed by the American Heart Association and the metabolic syndrome (MetS) in persons with cardiovascular disease (CVD). The aim of this study was to assess the prevalence of CVH and MetS and their correlation in the adult population of the Republic of Srpska, Bosnia and Herzegovina, in order to evaluate which set of cardiovascular risk factors (low or medium CVH status and MetS), or the combination of both, is a better predictor for the occurrence of CVD. METHODS: We included 3601 adults (aged ≥25 years) from the Republic of Srpska National Health Survey 2010. CVH status was evaluated according to the American Heart Association criteria, whereas MetS was defined using the criteria of the National Cholesterol Education Program's Adult Treatment Panel III. RESULTS: The prevalence of low or medium CVH status and MetS is significantly higher in participants who had experienced CVD than in those free of CVD. Our study showed that predictors for CVD occurrence were presence of MetS (odds ratio 3.61, 95% confidence intervals 2.14-6.07) and presence of both sets of cardiovascular risk factors in the same person (odds ratio 4.23, 95% confidence intervals 1.50-11.93). CONCLUSION: Our results suggest that presence of both sets of cardiovascular risk factors (low or medium CVH status and MetS) is the strongest predictor of CVD. Identification of individuals with cardiovascular risk factors may provide opportunities to intervene earlier and can help reduce the risk of developing CVD.

Inequalities in the utilization of health care services in a transition European country: results from the national population health survey.

OBJECTIVES: To examine demographic, socio-economic, and health status inequalities in the utilization of health care services (UHCS) in the Republic of Srpska (RS), Bosnia and Herzegovina. METHODS: Data were retrieved from the 2010 National Health Survey for the RS adult population (n = 4128). A complex sample design was taken into account for statistical analysis. RESULTS: As compared to men, a higher percentage of women visited a family physician (FP), urgent care department, dentist and private doctor. Higher educated women and those worse-off (OR 1.17) more frequently visited FP. Hospitalization (OR 4.56 for males; OR 9.17 for females), visit to urgent care department (OR 3.19 for males; OR 2.42 for females) and visits to FP in females (OR 1.46) were associated with poor self-perceived health. No inequalities by wealth index were found for the utilization of FP, hospitalization, urgent care and dentist among persons with poor self-perceived health status. CONCLUSIONS: The present study confirmed demographic, socio-economic and health status inequalities in the UHCS in RS. These findings have significant implications for health policy makers that seek to provide equal care for all people living in RS.

Sex inequalities in cardiovascular health: a cross-sectional study.

BACKGROUND: The aim of this study was to determine sex differences in the prevalence of cardiovascular health (CVH) metrics according to the CVH status. METHODS: The cross-sectional, population-based study involved 2250 women and 1920 men aged ≥18 years that participated in the 2010 National Health Survey in the Republic of Srpska, Bosnia and Herzegovina. Prevalence of CVH behaviours (smoking, body mass index, physical activity, diet), CVH factors (cholesterol, fasting blood glucose and blood pressure, plus smoking) and ideal CVH were estimated according to the American Heart Association criteria for ideal, intermediate and poor levels. Association between sex and ideal CVH categories was analyzed with multivariable logistic regression analysis across three age stratums. RESULTS: A higher prevalence of ideal CVH metrics was seen in women for smoking status, body mass index, healthy diet score and blood pressure, and in men for physical activity and total cholesterol. Women from all age groups had better CVH behaviours (odds ratio [OR] = 1.40 for the youngest; OR = 2.05 for middle-aged; and OR = 2.03 for older-aged women), while only women from the youngest age group had better CVH factors (OR = 5.09). In line with this, ideal overall CVH prevailed in younger and middle-aged women in comparison to men of the same ages (OR = 3.01 and OR = 2.25, respectively), while disappeared in older ones. CONCLUSIONS: Significant differences in the prevalence of CVH metrics between men and women in the Republic of Srpska should be considered in cardiovascular disease prevention.

Socio-Economic Differences in Cardiovascular Health: Findings from a Cross-Sectional Study in a Middle-Income Country.

BACKGROUND: A relatively consistent body of literature, mainly from high-income countries, supports an inverse association between socio-economic status (SES) and risk of cardiovascular disease (CVD). Data from low- and middle-income countries are scarce. This study explores SES differences in cardiovascular health (CVH) in the Republic of Srpska (RS), Bosnia and Herzegovina, a middle-income country. METHODS: We collected information on SES (education, employment status and household's relative economic status, i.e. household wealth) and the 7 ideal CVH components (smoking status, body mass index, physical activity, diet, blood pressure, total cholesterol, and fasting blood glucose) among 3601 participants 25 years of age and older, from the 2010 National Health Survey in the RS. Based on the sum of all 7 CVH components an overall CVH score (CVHS) was calculated ranging from 0 (all CVH components at poor levels) to 14 (all CVH components at ideal levels). To assess the differences between groups the chi-square test, t-test and ANOVA were used where appropriate. The association between SES and CVHS was analysed with multivariate linear regression analyses. The dependent variable was CVHS, while independent variables were educational level, employment status and wealth index. RESULTS: According to multiple linear regression analysis CVHS was independently associated with education attainment and employment status. Participants with higher educational attainment and those economically active had higher CVHS (b = 0.57; CI = 0.29-0.85 and b = 0.27; CI = 0.10-0.44 respectively) after adjustment for sex, age group, type of settlement, and marital status. We failed to find any statistically significant difference between the wealth index and CVHS. CONCLUSION: This study presents the novel information, since CVHS generated from the individual CVH components was not compared by socio-economic status till now. Our finding that the higher overall CVHS was independently associated with a higher education attainment and those economically active supports the importance of reducing socio-economic inequalities in CVH in RS.

Status of cardiovascular health in a transition European country: findings from a population-based cross-sectional study.

OBJECTIVES: Our aim was to assess the prevalence of ideal cardiovascular health (CVH) in the adult population of Republic of Srpska (RS), Bosnia and Herzegovina, and its relationship with socio-demographic characteristics of participants. METHODS: We included 4,170 adults (mean age 50.2 years; 54 % women) from the National Health Survey performed from September to November 2010 in RS. Population prevalence of CVH health metrics (smoking, body mass index, physical activity, diet, cholesterol, blood pressure, and glucose) were estimated according to the American Heart Association criteria for "ideal", "intermediate", and "poor" levels. RESULTS: Only 0.02 % participants had ideal (all 7 health metrics at ideal levels), 7.6 % intermediate, and 92.4 % poor (at least one metric at poor level) CVH. The fasting glucose was the most prevalent (75.9 %), whereas the healthy diet was the least prevalent (4.4 %) ideal CVH metric. CONCLUSIONS: Our study indicates extremely low prevalence of ideal and high prevalence of poor CVH in the adult RS population. Such alarming results require urgent action. Comprehensive public health strategies and interventions must be developed to assist individuals and population in improving their CVH.

Association of socioeconomic status measured by education, and cardiovascular health: a population-based cross-sectional study.

OBJECTIVE: Cardiovascular health (CVH) is a relatively new concept defined by the American Heart Association (AHA). The aim of the present study was to assess whether the indices of CVH were discriminators of socioeconomic status (SES) in the adult population of the Republic of Srpska (RS). DESIGN: Population-based cross-sectional study. SETTING: RS, Bosnia and Herzegovina. PARTICIPANTS: The study involved 4165 adults aged ≥18 years (mean age 50.2; 54% women) who participated in the National Health Survey performed from September to November 2010 in the RS. STUDY VARIABLES: Participant's education was a proxy for SES. Potential discriminators of SES were indices of CVH presented according to AHA as: ideal health behaviours index (non-smoking, body mass index <25 kg/m(2), physical activity at goal level and healthy diet); ideal health factors index (untreated total cholesterol <200 mg/dL, untreated blood pressure <120/<80 mm Hg, untreated fasting glucose <100 mg/dL and non-smoking); and ideal CVH status (defined as all seven ideal health metrics present) versus intermediate and poor CVH status. RESULTS: Participants with high educational levels had a significantly greater number of ideal CVH metrics, and ideal health factor metrics compared with those with low or medium educational level (OR 0.88 95% CI 0.77 to 0.99 and OR 0.88 95% CI 0.80 to 0.96; OR 0.81 95% CI 0.69 to 0.96 and OR 0.77 95% CI 0.68 to 0.87; respectively). The number of ideal behaviour metrics was not a discriminator of educational groups. Concerning the categories of CVH status the poor CVH was a discriminator for low and medium education compared with those with high education (OR 1.93 95% CI 1.24 to 3.01 and OR 1.54 95% CI 1.08 to 2.19, respectively). CONCLUSIONS: Our findings emphasise the large potential for preventing cardiovascular disease, showing a low proportion with a favourable CVH profile, especially among low-educated people. It is necessary to consider prevention strategies aimed at improving CVH in RS, targeting primarily low educational groups.

The Children's Dermatology Life Quality Index (CDLQI): linguistic and cultural validation in Serbian.

BACKGROUND: The Children's Dermatology Life Quality Index (CDLQI) evaluates the impact of skin diseases on the patient's quality of life. OBJECTIVE: The purpose of the study was to translate and to validate the CDLQI into Serbian. METHODS: The CDLQI was translated into Serbian following international recommendations for translation and cultural adaptation. The validation study was carried out on a large cohort of secondary schoolchildren who self-reported acne. RESULTS: Translating the CDLQI consisted of forward translation, reconciliation, back translation, back-translation review, and cognitive debriefing. The good internal consistency of the scale was demonstrated with a Cronbach alpha coefficient of 0.87. A Spearman correlation coefficient of 0.66 between the CDLQI and the Cardiff Acne Disability Index (CADI) was deemed satisfactory to demonstrate concurrent validity. CONCLUSION: The translation, cross-cultural adaptation, and psychometric qualities of the CDLQI were satisfactory, enabling its application in clinical practice and future studies.
