Aims and background: To summarize risk factors for bladder cancer, emphasizing the role of recently established associations and to present some ongoing debates on the issue. Methods: A systematic literature search was performed using MEDLINE database on bladder cancer risk factors between January 1985 and June 2006 and by detailed examination of the references of original articles, reviews and monographs retrieved. Results: Cigarette smoking is recognized as the main cause of bladder cancer and accounts for about 50% of cases in developed countries. A strong link exists between the amount and duration of cigarette smoking. A high risk of bladder carcinoma has been observed in workers exposed to some aromatic amines. Based on these and other occupational risks, it has been estimated that 5-10% of bladder carcinomas in industrialized countries were due to exposures of occupational origin. Infectious agents have a major influence on bladder cancer risks in the areas of the world where Schistosoma haematobium infestation is endemic. Other potential risk factors for bladder cancer are other urinary tract infections and drinking tap water with chlorination by-products or arsenic. Exposure to certain drugs, like cyclophosphamide used in chemotherapy and heavy consumption of phenacetin-containing analgesics, has been shown to cause bladder cancer in humans. Total fluid intake and high consumption of fruits and vegetables are probably associated with a small decrease in risk. Conclusions: Avoidance of tobacco smoking and incriminated occupational exposures, habitual intake of fresh fruits and vegetables, and prevention and control of urinary tract infections should be recommended for bladder cancer prevention. Further studies are required to assess the role of genetic polymorphisms and their modifying effect of lifestyle risk factors for bladder cancer occurrence and to evaluate the benefit of bladder cancer screening, particularly in those at high risk.

Background: In the last decade of the 20th century, a considerable effort has been put into the development of summary measures of population health that combine information on mortality and non-fatal health outcomes. We used the DALYs (Disability adjusted life years) method to assess the burden of disease and injury in the population of Serbia. Methods: Our study, largely based on the methods developed for the Global burden of disease study, was conducted between October 2002 and September 2003. DALYs, stratified by gender and age, were calculated for 18 selected health conditions for the population of Serbia, Serbia and Montenegro for 2000. Years of life lost (YLL) were calculated using country mortality statistics, while years lived with disability (YLD) were calculated using different sources of information. Also, the YLD/YYL ratio and age-adjusted rates of DALYs were calculated. Results: Ischaemic heart disease, cerebrovascular diseases, lung cancer, unipolar depressive disorders, and diabetes mellitus were responsible for almost two-thirds (70%) of the total burden of 18 selected disorders in Serbia 2000. The leading five causes for males were ischaemic heart disease (26.1 DALY per 1000), stroke (17.9), lung cancer (12.7), road traffic accidents (6.5), and self-inflicted injuries (5.5). For females, the leading five causes were stroke (18.1 DALY per 1000), ischaemic heart disease (14.1), depression (8.7), breast cancer (6.1), and diabetes mellitus (5.2). Conclusions: The final results of the study have shown that the national health priority areas should cover cardiovascular diseases, cancers, and mental health.

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.
