Characteristics and quality of life of substance users and their caregivers.

The correlation between substance use and depression has been emphasized in the literature. Substance use disorders can also adversely affect the caregivers of drug-addicted persons. A cross-sectional study was conducted at the Special Hospital for Addiction Diseases in Belgrade in 2015 to analyze the characteristics, consequences, and health-related quality of life of drug users and their caregivers. The sample comprised 136 users of various substances, and 136 caregivers. A questionnaire on socio-demographic characteristics, the Short Form Health Survey 36 (SF-36), and Beck Depression Inventory were administered to all participants. According to multivariate logistic regression analysis, compared with caregivers, substance users were significantly more frequently male (P < .001), ≤ 39 years old (P < .001), and more frequently reported the use of sedatives (P = .009) and smoking (P < .001). Some level of depression was present in all participants, but severe forms were more frequent in substance users (P = .010). Among substance users, mean scores of SF-36 domains ranged from 56.62‒87.17, and among their caregivers, from 50.37‒75.07; however, the difference was significant only for the health change domain (P = .037), the score for which was lower in caregivers. Substance users suffered from more severe forms of depression compared to their caregivers, who had lower SF-36 scores in the domain of health change.

Anxiety and depression in patients with vocal fold nodules, edema and polyps.

PURPOSE: To compare the prevalence and severity of depression and anxiety among patients with vocal fold (VF) nodules, polyps and edema. At the same time the aim was to analyse association between severity of distress and the level of vocal handicap as well as to identify other factors related to severity of depression and anxiety in these patients. METHODS: To all participants were given five questionnaires: (1) questionnaire on socio-demographic and some other characteristics of patient; (2) Beck's Depression Inventory (BDI); (3) State-Trait Anxiety Inventory (STAI) 1 (State Anxiety); (4) STAI 2 (Trait Anxiety); and (5) Voice Handicap Index (VHI)-10. RESULTS: A total of 205 patients were included in this study. Mild-to-severe depression, according to BDI was present in 79 (38.6%) patients. Mild-to-severe state anxiety and trait anxiety were present in 199 (97.1%) and 200 (97.6%) patients, respectively. Only 10 patients had VHI-10 score ≤ 11. Multivariate analyses showed that there were no significant differences in the level of depression and anxiety between patients with VF nodules, polyps and edema. The VHI-10 score was significantly higher in patients with VF edema in comparison with VF nodule patients (p = 0.001), as well as in comparison with VF polyp patients (p = 0.001). CONCLUSION: The present study identified a high prevalence of psychological and vocal distress among patients with vocal disorders. Severity of depression and anxiety did not differ between patients with VF nodules, polyps and edema, and it was not related to the level of vocal handicap.

The prevalence of polyvascular disease in patients with carotid artery disease and peripheral artery disease.

BACKGROUND: Cardiovascular disease remains the major cause of mortality in the Western World. AIMS: We aimed to assess the prevalence of polyvascular disease in patients with carotid artery disease and peripheral artery disease (PAD), and to determine the risk profile of patients with polyvascular disease. METHODS: The study included 1045 consecutive patients presenting to our department with carotid disease or PAD. Demographic characteristics, anthropometric parameters, and data on cardiovascular risk factors were collected in all patients. On the basis of medical history, patients were classified into those who had only symptomatic carotid disease or symptomatic PAD and those who had symptomatic polyvascular disease. RESULTS: Carotid disease alone was reported in 366 participants (35%), PAD alone, in 199 (19%), and polyvascular disease, in 480 (46%). Compared with carotid disease, PAD was more often a component of polyvascular disease (P = 0.002) and was combined with a higher number of other atherosclerotic diseases (P = 0.02). Compared with patients with symptomatic atherosclerotic disease in only 1 territory, patients with various types of polyvascular disease more often had hypertension (P from 0.03 to <0.001), dyslipidemia (P <0.001), high­sensitivity C­reactive protein levels of 3 mg/l or higher (P = 0.005), and more often were current smokers (P <0.001) or former smokers (P from 0.03 to 0.001). CONCLUSIONS: We showed a high prevalence of symptomatic polyvascular disease in patients with carotid disease or PAD. The risk profile was worse in patients with polyvascular disease than in those with a disease in a single vascular territory.

Oral sex related knowledge and oral sex behavior among homosexual and heterosexual men in Belgrade: A cross-sectional study.

BACKGROUND: Although the risk of sexually transmitted infections is far greater during vaginal and anal sex than during oral sex, increasing practice of oral sex and low rates of barrier method use will probably increase the relative importance of oral sex as a route of transmission for genital pathogens. AIMS: The aim of this study was to evaluate knowledge and attitudes about oral sex and sexually transmitted infections, as well as oral sex practices, both among heterosexuals and homosexual men and to compare those two groups. MATERIALS AND METHODS: In this cross-sectional study, data were collected from consecutive sexually active male patients who ever had oral sex and who attended counselling for sexually transmitted infections at the City Institute for Skin and Venereal Diseases in Belgrade from March to June 2016. One dermatologist interviewed all participants. RESULTS: The study included 359 men who ever had oral sex, 95 (26.5%) homosexual and 264 (73.5%) heterosexual men. In comparison with heterosexual men, homosexual men had considerably more lifetime sexual partners and oral sex partners during the past 3 months, and significantly more frequently practiced oral-anal sex. Oral-sex related knowledge of all participants was unsatisfactory [correct answers were given by 95 (26.5%) to 277 (77.2%) participants], but it was significantly better in homosexual men than in heterosexual. Frequency of condom use and human immunodeficiency virus testing was also significantly higher in the case of homosexual than heterosexual men. LIMITATIONS: The study was not performed in representative sample of population. It was restricted to the patients. Consequently it is questionable whether the results obtained could be generalized. CONCLUSION: Oral sex related knowledge deficits and risky oral sex practice exist in both homosexual and heterosexual men. These findings indicate a need for effective public health campaign and patient education about the risks of unprotected oral sex.

Awareness and knowledge of cardiovascular disease risk factors among medical students.

BACKGROUND: The aim of this study was to assess the knowledge and attitude of medical students in relation to cardiovascular disease (CVD) risk factors as well as to assess the impact of medical education on their knowledge and recognition of the importance of implementation of preventive measures. METHODS: This cross-sectional study included 514 students in the second year of studying at the Faculty of Medicine in Belgrade, Serbia (younger students response rate 79.57%) and 511 students in the last year of education (older students response rate 90.21%). For data collection, an anonymous self-administered questionnaire was used, which included two types of questions about CVD risk factors and questions about the student's attitude. RESULTS: Older students knew significantly more about CVD risk factors than students who were at the beginning of their medical studies; however, more than half of the older students did not know the correct answers about CVD risk factors. The only exceptions were questions about "bad" and "good" cholesterol, metabolic syndrome (MSy) and lipid lowering therapy in high risk subjects. Physical inactivity, obesity, type 2 diabetes, smoking and hypertension were not ranked highly enough as important CVD risk factors. Compared groups of students did not significantly differ in attitude scores. The majority of them recognized CVD as the leading cause of death, had normal weight and knew their own blood pressure. CONCLUSION: Knowledge of medical students from Belgrade about CVD risk factors should be improved.

Comparison of different anthropometric measures in the adult population in Serbia as indicators of obesity: data from the National Health Survey 2013.

OBJECTIVE: The present study aimed to compare different indicators of obesity in the Serbian adult population. DESIGN: Cross-sectional study. A stratified, two-stage, national-representative random sampling approach was used for the selection of the survey sample. Data sources were questionnaires created according to the European Health Interview Survey questionnaire. Measurements of weight, height and waist circumference (WC) were performed using standard procedures. Anthropometric measures included BMI, WC and waist-to-height ratio (WHtR). SETTING: Data for the study were obtained from the 2013 National Health Survey, performed in line with the EUROSTAT recommendations for performance of the European Health Interview Survey. SUBJECTS: Adults aged ≥20 years. RESULTS: According to BMI, out of the whole studied population (12 460 adults of both sexes) 2·4 % were underweight, 36·4 % overweight and 22·4 % obese. Using WC and WHtR as measures of adiposity showed that 22·5 % and 42·8 % of participants were overweight and 39·8 % and 25·3 % were obese, respectively. Men and women differed significantly in all variables observed. Overweight was more frequent in men and obesity in women regardless of adiposity measure used. CONCLUSIONS: In spite of strong correlations between BMI, WC and WHtR, substantial discrepancies between these three measures in the assessment of overweight and obesity were found, especially in some age groups. Which of these anthropometric measures should be used, or whether two or all three of them should be applied, depends on their associations with cardiovascular or some other disease of interest.

Relationship between health behaviour and body mass index in the Serbian adult population: data from National Health Survey 2013.

OBJECTIVES: To determine relationship between health behaviour and body mass index (BMI) in a Serbian adult population. METHODS: Study population included adults aged 20 and more years. A stratified, two-stage national representative random sampling approach was used for the selection of the survey sample. RESULTS: Regarding BMI, out of the 12,461 subjects of both sexes, 2.4 % were underweight, 36.5 % overweight and 22.4 % obese. Multivariate logistic regression analysis showed that both in men and women, risk factors for obesity were former smoking, irregular eating breakfast and low physical activity level, while in women only risk of obesity was associated with alcohol consumption. In both sexes, risk factors for overweight were former smoking and low physical activity level, and in women additionally those were alcohol consumption, irregular eating breakfast, always adding salt to meals and consumption of 2-4 portions of fruit daily. Smoking and irregular eating of breakfast in men were risk factors for underweight. CONCLUSIONS: Physical activity, alcohol consumption, smoking, irregular breakfast consumption, adding salt to meals, frequency of vegetable and fruit consumption were related to BMI in adult Serbian population.

Chronic venous disease: Correlation between ultrasound findings and the clinical, etiologic, anatomic and pathophysiologic classification.

OBJECTIVE: The aim of the study was to investigate association between clinical manifestation of chronic venous disease and the presence and severity of functional venous disease. METHOD: A cross-sectional study was conducted in 14 towns in Serbia. All men and women aged >18 years, consecutively coming to venous specialists (47 specialists) were included in the study. Patients who were previously treated for chronic venous disease were excluded. Patients were classified according to the clinical category of clinical, etiologic, anatomic and pathophysiologic classification for chronic venous disease. Reflux and/or obstruction were determined by using a color duplex ultrasound. RESULTS: The study included 1679 chronic venous disease patients. Color duplex ultrasound was performed in 1029 (61.3%) of them who formed the final study group. Reflux was found in 76.8% of patients - 53.1% had reflux in superficial, 7.2% in deep and 16.1% in perforator veins. Obstruction was found in 31.9% of patients - superficial in 14.8% of patients and deep in 16.9%. Deep obstruction was even found in clinical, etiologic, anatomic and pathophysiologic C0s-C1 categories. Reflux and obstruction combined were revealed in 19.1% of patients. Reflux in deep and perforator veins and reflux and obstruction combined were significantly associated with clinical, etiologic, anatomic and pathophysiologic clinical categories being the most frequent in patients with venous ulcers. CONCLUSION: Clinical, etiologic, anatomic and pathophysiologic clinical categories of chronic venous disease are strongly correlated with functional disease especially with reflux in deep and perforator veins, and reflux and obstruction combined. The presence of deep obstruction in patients with chronic venous disease belonging to clinical, etiologic, anatomic and pathophysiologic C0s-C1 category could justify recommendation for color duplex ultrasonography in all patients with symptoms of chronic venous disease but without clear clinical signs.

Trends in mortality rates from coronary heart disease in Belgrade (Serbia) during the period 1990-2010: a joinpoint regression analysis.

BACKGROUND: Coronary heart disease (CHD) causes an estimated 7 million deaths worldwide each year. In the last few decades, mortality from CHD has been decreasing in many countries. The aim of this study was to analyze the trends of mortality from CHD and myocardial infarction (MI) in the population of Belgrade during the period 1990-2010. METHODS: Mortality data for CHD and MI were obtained from the Municipal Institute of Statistics in Belgrade and used to calculate age- and sex-specific and age-adjusted mortality rates. Joinpoint regression analysis was used to estimate annual percent changes (APCs) in mortality and to identify points in time where significant changes in trend occur. RESULTS: Trends in CHD mortality rates showed significant decline in men during the period studied (APC -0.5%, no joinpoints detected), but no significant change among women (APC +0.4%, no joinpoints detected). While we observed significant declines in CHD mortality in men aged 35-44, 55-64 and 65-74 and women aged 55-64, there was a significant increase in mortality in men aged ≥85 and women aged 75-84 and ≥85. Trends in MI mortality rates showed similar patterns in both genders, with a significant decline from the mid-1990s. Significant decline in MI mortality was observed in almost all age groups, except the two oldest (75-84 and ≥85) in women population. CONCLUSIONS: Given that CHD and MI mortality trends showed different patterns during the period studied, especially in women, our results imply that further observation of trend is needed.

Quality of life in chronic venous disease patients measured by short Chronic Venous Disease Quality of Life Questionnaire (CIVIQ-14) in Serbia.

BACKGROUND: This was a psychometric validation of the short Chronic Venous Disease Quality of Life Questionnaire (CIVIQ-14) as quality of life (QOL) instrument for chronic venous disease (CVD) patients. METHODS: Patients aged >18 years who had CVD in CEAP C stages C0s to C6 were included in the study. Diagnosis was made by general practitioners according to CVD symptoms and visual examination of the lower extremities. QOL was assessed with the self-administrated CIVIQ-14. The reliability, construct, and convergent validity of the CIVIQ-14 was estimated as well as QOL of CVD patients according to CEAP C stages. RESULTS: The study comprised 2260 subjects who fully completed the CIVIQ-14. CIVIQ-14 had a high level of reliability, construct, and convergent validity, but the structure of its three dimensions (pain [P], physical [PHY], and psychological [PSY]) was suboptimal. After adjustment for age, body mass index, and number of CVD symptoms, CIVIQ -14 global, P, PHY, and PSY scores showed significant progressive reduction of QOL from CEAP class C0s to C6. These differences were present in both sexes. The progressive impairment of the QOL involved primarily the pain and the physical items. For all CEAP C classes, the P and PHY scores were lower than the PSY scores. Global scores for men and women were: 76.7 and 73.9 for C0s; 75.5 and 70.6 for C1; 67.8 and 64.5 for C2; 68.3 and 61.6 for C3; 60.7 and 54.6 for C4; 49.5 and 50.2 for C5; and 41.3 and 46.7 for C6. CONCLUSIONS: CVD in the lower extremities has a substantial effect on both physical and psychologic aspects of QOL, the physical aspects of QOL (P and PHY items) being more important. CIVIQ-14 is valuable in assessing QOL in CVD patients. Further investigations are necessary to confirm the stability of its two dimensions.

Prevalence of the metabolic syndrome in patients with carotid disease according to NHLBI/AHA and IDF criteria: a cross-sectional study.

BACKGROUND: Metabolic syndrome (MetS) has been related to type 2 diabetes and cardiovascular diseases. Different criteria for diagnosis of MetS have been recommended, but there is no agreement about which criteria are best to use. The aim of the present study was to investigate agreement between the National Heart, Lung, and Blood Institute, American Heart Association (NHLBI/AHA) and the International Diabetes Federation (IDF) definitions of MetS in patients with symptomatic carotid disease and to compare the frequency of cardiovascular risk factor in patients with MetS diagnosed by these two sets of criteria. METHODS: The study was a cross-sectional one involving 644 consecutive patients with verified carotid disease who referred to the Vascular Surgery Clinic Dedinje in Belgrade during the period April 2006 - November 2007. Anthropometric parameters blood pressure, fasting plasma glucose and lipoproteins were measured using standard procedures. RESULTS: MetS was present in 67.9% of participants, according to IDF criteria, and in 64.9% of participants, according to the NHLBI/AHA criteria. A total of 119 patients were categorized differently by the two definitions. Out of all participants 10.7% had MetS by IDF criteria only and 7.8% of patients had MetS by NHLBI/AHA criteria only. The overall agreement of IDF and NHLBI/AHA criteria was 81.5% (Kappa 0.59, p < 0.001). In comparison with patients who met only IDF criteria, patients who met only NHLBI/AHA criteria had significantly more frequently cardiovascular risk factors with the exception of obesity which was significantly more frequent in patients with MetS diagnosed by IDF criteria. CONCLUSION: The MetS prevalence in patients with symptomatic carotid disease was high regardless of criteria used for its diagnosis. Since some patients with known cardiovascular risk factors were lost by the use of IDF criteria it seems that NHLBI/AHA definition is more suitable for diagnosis of MetS. Large follow-up studies are needed to test prognostic value of these definitions.

Cigarette smoking, coffee intake and alcohol consumption preceding Parkinson's disease: a case-control study.

OBJECTIVE: A case-control study was performed in Belgrade in order to investigate the association between Parkinson's disease (PD) and smoking, coffee and alcohol consumption. METHODS: During the period 2001-2005, 110 new PD cases and 220 hospital controls were interviewed. Cases and controls were matched by sex, age and place of residence (urban/rural). For the analysis of data conditional univariate and multivariate logistic regression methods were used. RESULTS: With PD were associated, independently from each other, current smoking [odds ratio (OR) = 0.44; 95% confidence interval (CI) = 0.23-0.82], alcohol consumption (OR = 4.78; 95% CI = 2.67-8.55) and coffee consumption (OR = 2.54; 95% CI = 1.36-4.75). In ever smokers the risk for PD significantly decreased with the increasing number of cigarettes smoked and with increasing duration of smoking. The risk for PD significantly increased with the increasing quantity of alcohol consumption. PD risk was significantly higher in subjects whose average daily consumption of coffee was 1 and 2-3 cups, and it was lower (but not significantly) in those whose daily coffee consumption was 4+ cups. Cases and controls did not differ in duration of alcohol and coffee consumption. The results of multivariate analyses did not substantially change after adjustment on family history positive on PD. CONCLUSION: The findings of this study support the hypotheses of inverse association of smoking with PD, but an inverse association with coffee was not confirmed. PD was found to be positively associated with coffee and alcohol consumption.

Environmental factors and Parkinson's disease: a case-control study in Belgrade, Serbia.

A case-control study was performed in Belgrade in order to investigate the association between Parkinson's disease (PD) and some environmental factors. During the period 2001-2005, 110 new PD cases and 220 hospital controls were interviewed. Cases and controls were matched by sex, age (+/-2 years), and place of residence (urban/rural). According to multivariate conditional logistic regression analysis, PD was positively asssociated with exposure to insecticides (odds ratio (OR) 3.22, 95% confidence interval (95% CI) 1.32-7.87), dyes (OR 25.33; 95% CI, 2.89-222.0), and naphtha and its derivates (OR 9.53; 95% CI, 1.04-86.96), and with gardening (OR 5.51; 95% CI, 3.04-10.01), well water drinking (OR 2.62; 95% CI, 1.40-4.90), and spring water drinking (OR 2.19; 95% CI, 1.15-4.16). Negative association was found for service-sector working (OR 0.15; 95% CI, 0.04-0.59). The results obtained did not changed after adjustment for smoking. The findings of the present study support the role of environmental factors in the occurence of PD.

Association of socioeconomic status measured by education and risk factors for carotid atherosclerosis: cross-sectional study.

AIM: To investigate the association between socioeconomic status and metabolic syndrome, lifestyle, clinical and biochemical characteristics, and inflammatory markers as risk factors for carotid atherosclerotic disease. METHODS: This cross-sectional study, involving 657 consecutive patients with verified carotid atherosclerotic disease, was performed in Belgrade, Serbia, during the period 2006-2007. Formal education level was used as a proxy for socioeconomic status. Anthropometric parameters and data on cardiovascular risk factors were analyzed in participants with different levels of education--low (< or = primary school), medium (secondary school), and high (university education). In the analysis, univariate and multivariate logistic regressions were used. RESULTS: Multivariate analysis showed that low education was significantly positively associated with female sex (odds ratio [OR], 2.38; 95% confidence interval [CI], 1.45-3.81), increased triglycerides (OR, 1.79; 95% CI, 1.12-2.78), increased high-sensitivity C-reactive protein (hsCRP) (OR, 3.53; 95% CI, 2.17-5.88), and physical inactivity (OR, 4.24; 95% CI, 1.82-9.86) and negatively associated with former smoking (OR, 0.42; 95% CI, 0.23-0.75). Medium education was significantly positively associated with increased triglycerides (OR, 1.73; 95% CI, 1.14-2.62) and increased hsCRP (OR, 2.17; 95% CI, 1.37-3.41), and negatively with age (OR, 0.97; 95% CI, 0.94-0.99). CONCLUSION: Increased triglycerides and hsCRP in people with low and medium education, and high prevalence of metabolic syndrome, its components and inflammatory markers in all study participants, suggest that regular health check-up, especially for those with lower education, may be useful in early detection and treatment of any abnormality that can be associated with cardiovascular disease.

Case-control study of anaplastic thyroid cancer: goiter patients as controls.

Anaplastic thyroid cancer is very serious disease with bad prognosis and unknown etiology. The aim of the study was to test some hypotheses about other factors in addition to goiter related to anaplastic thyroid cancer occurrence. A case-control study was performed during the period 1993-2005. The case group comprised 126 patients with newly diagnosed anaplastic thyroid cancer. The control group comprised 252 patients who had for the first time goiter operation, and had no malignancy of thyroid gland. Cases and controls were individually matched by age, sex and place of residence (urban/rural). According to conditional multivariate logistic regression analysis, anaplastic thyroid cancer was significantly related to lower education (odds ratio=1.85, 95% confidence interval=1.21-2.82), other malignant tumors in personal history (odds ratio=4.37, 95% confidence interval=1.11-17.31), blood group B (odds ratio=3.69, 95% confidence interval=1.10-12.49), menarche at >or=15 years of age (odds ratio=2.63, 95% confidence interval=1.15-5.88), and first full-term pregnancy before 19 years of age (odds ratio=2.96, 95% confidence interval=1.26-6.96). On the basis of the results obtained, risk factors for anaplastic thyroid cancer are similar to risk factors for differentiated thyroid cancers.

Case-control study of oropharyngeal cancer.

BACKGROUND: In order to test some hypotheses of risk factors for oropharyngeal cancer (neoplasm of base of tongue, palate and tonsils) matched case-control study was conducted in Belgrade, Serbia and Montenegro, during the period 1998-2000. METHODS: Study comprised 100 incidence cases with oropharyngeal cancer and 100 controls with some non-malignant diseases of head and neck. RESULTS: According to multivariate analysis, ever smoking, interaction between smoking and alcohol consumption, and occupational exposure to wood dust were found to be independent risk factors for oropharyngeal cancer (odds ratio-OR=5.10 95% confidence intervals-95% CI=1.70-15.27, OR=2.61 95% CI=1.54-4.41, and OR=4.16 95% CI=1.45-11.91, respectively). CONCLUSION: The results of the present study are in line with other authors' findings showing that smoking and alcohol consumption are the main risk factors for oropharyngeal cancer. The effect of occupational exposure to wood dust warrants further investigation.

Risk factors for Peyronie's disease: a case-control study.

OBJECTIVE: To test some hypotheses about risk factors for Peyronie's disease (PD). PATIENTS AND METHODS: In a case-control study, 82 patients with PD, consecutively diagnosed at the first author's institution, were compared with 246 men visiting the same institution for dermatological diseases. Univariate and multivariate logistic regression analyses were used to assess the data. RESULTS: From the multivariate logistic regression analysis the risk factors for PD were: a history of genital and/or perineal injuries, transurethral prostatectomy, cystoscopy, diabetes mellitus, hypertension, lipoma, propranolol in therapy, Dupuytren's contracture in the medical history, ever having smoked, alcohol consumption, fibromatous lesions of the genital tract of the partner, and surgical intervention on the genital tract of the partner. CONCLUSION: The results of the present study are in line with the hypothesis that, in addition to genetic predisposition, trauma of the penis and systemic vascular diseases are risk factors for PD. Smoking and alcohol consumption also seem to have some role in the development of the disease.

The Belgrade childhood diabetes study: a multivariate analysis of risk determinants for diabetes.

BACKGROUND: The aim of this study was to evaluate some hypotheses about factors related to the development of type 1 diabetes mellitus. METHODS: A case-control study was conducted in Belgrade during the period 1994-1997. A total of 105 recently onset diabetic and 210 control children, individually matched by age (+/-1 year), sex and place of residence, were included in the study. RESULTS: According to multivariate regression analysis, the following factors were related to type 1 diabetes: stressful events and symptoms of psychological dysfunction during the 12 months preceding the onset of the disease [odds ratio (OR) 3.48, 95% confidence interval (CI) 2.15-5.65; and OR 2.15, 95% CI 1.33-3.48], irregular vaccination (OR 16.98, 95% CI 1.38-208.92), infection during 6 months preceding the onset of the disease (OR 4.23, 95% CI 1.95-9.17), higher education of father (OR 1.50, 95% CI 1.05-2.14), mother's consumption of nitrosoamines-rich food during pregnancy (OR 4.33, 95% CI 1.95-9.61), alcohol consumption by father (OR 3.80, 95% CI 1.64-8.78), insulin-dependent and non-insulin-dependent diabetes mellitus in three generations of children's relatives (OR 20.04, 95% CI 4.73-84.81; and OR 5.52, 95% CI 2.45-12.46), and use of ultrasound diagnostic techniques during pregnancy (OR 0.42, 95% CI 0.17-1.00). CONCLUSIONS: Among non-genetic factors, those affecting the child during pregnancy are especially important because of their preventability.

Hereditary patterns of Belgrade university female students with migraine and nonmigraine primary headache.

Various studies have provided evidence that migraine is a multifactorial genetic disorder. The aim of the present study was to compare hereditary patterns of female students with migraine (245 subjects) and non-migraine primary headaches (1053 subjects). The prevalence study was performed combined with a case-control study. Migraineurs had significantly more frequently one or more first-degree and/or second-degree relatives with migraine. Students with menstrual migraine, in comparison with other subtypes of migraine (with the exception of premenstrual migraine), had significantly more frequently > or = 2 relatives with migraine. Among students with non-migraine primary headaches, those with menstrually related headache had more frequently relatives with migraine in comparison with students suffering from menstrually unrelated nonmigraine headache. The results obtained are in line with the results of genetic epidemiologic studies suggesting that genetic factors play a role in the occurrence of migraine.
