A cross sectional study of sex differences in self-medication practices among university students in Slovenia

Self-medication patterns in adults depend on sex. Self-medication among students is very common, but little is known about the influence of sex. The aim of the study was to determine the incidence of self-medication college students and to determine the effect of sex on self-medication patterns. A web based incidence study conducted on a sample of Slovenian university students. The main outcome measures were percentages of male and female students reporting the use of self-medication in the past year. A majority of students (92.3%) reported the use of some sort of self-medication in the past year. Most female students (94.1%) and most male students (90.9%) reported the use of self-medication in the past year. The difference was not statistically significant. More female students than male ones (p < 0.05) acquired the drugs for self-medication in pharmacies, used OTC drugs, herbal teas, herbs, vitamins and minerals, remedies for muscle mass gain, antibiotics, benzodiazepines, antacids, acetylsalicylic acid, topical corticosteroids, and nasal decongestives only with the advice of physicians or pharmacists, and thought that increasing drug dosage can be dangerous, that in case of side effects physicians' help must be sought, that no drug can be used during pregnancy, and that self-treatment can mask the symptoms and signs of diseases so the physicians can overlook them easily. Sex appears to be important factor in self-medication patterns even in young adults, such as students. The physicians should actively seek the presence of self-medication in this population. Inappropriate or unsafe use should be properly addressed and managed.     

Prevalence of hardcore smoking in England,and associated attitudes and beliefs: cross sectional study

Objective To quantify the prevalence and characteristics of hardcore smokers in England.Design Cross sectional survey.Setting Interview in respondents'' household.Participants 7766 adult cigarette smokers.Main outcome measures Hardcore smoking defined by four criteria (less than a day without cigarettes in the past five years; no attempt to quit in the past year; no desire to quit; no intention to quit), all of which had to be satisfied.Results Some 16% of all smokers were categorised as hardcore. Hardcore smoking was associated with nicotine dependence, socioeconomic deprivation, and age, rising from 5% in young adults aged 16-24 to 30% in those aged ≥ 65 years. Hardcore smokers displayed distinctive attitudes towards and beliefs about smoking. In particular they were likely to deny that smoking affected their health or would do so in the future. Prevalence of hardcore smoking was almost four times higher than in California.Conclusion Hardcore smoking presents a serious challenge to public health efforts to reduce the prevalence of smoking, but the proportion of hardcore smokers does not necessarily increase as overall prevalence in a population declines. More hardcore smokers could be persuaded to quit, but this will require interventions that are targeted to the particular needs and perceptions of both socially disadvantaged and older smokers.     

Prevalence and patterns of smoking in Delhi: cross sectional study.

OBJECTIVE--To determine the prevalence and predictors of smoking in urban India. DESIGN--Cross sectional. SETTING--Delhi, urban India, 1985-6. SUBJECTS--Random sample of 13,558 men and women aged 25-64 years. MAIN OUTCOME MEASURES--Smoking prevalence; subjects who were currently smoking and who had smoked > or = 100 cigarettes or beedis or chuttas in their lifetime were defined as smokers. RESULTS--45% (95% confidence interval 43.8 to 46.2) of men and 7% (6.4 to 7.6) of women were smokers. Education was the strongest predictor of smoking, and men with no education were 1.8 (1.5 to 2.0) times more likely to be smokers than those with college education, and women with no education were 3.7 (2.9 to 4.8) times more likely. Among smokers, 52.6% of men and 4.9% of women smoked only cigarettes while the others also smoked beedi or chutta. Compared with cigarette smokers, people smoking beedi or chutta were more likely to be older and married; have lower education, manual occupations, incomes, and body mass index; and not drink alcohol or take part in leisure exercise. CONCLUSION--There are two subpopulations of smokers in urban India, and the prevention strategy required for each may be different. The educated, white collar cigarette smoker in India might respond to measures that make non-smoking fashionable, while the less educated, low income people who smoke beedi or chutta may need strategies aimed at socioeconomic improvement.     

Impact of HIV on tuberculosis in Zambia: a cross sectional study.

OBJECTIVE--To examine the contribution of HIV infection to the apparently increasing incidence of tuberculosis in central Africa. DESIGN--Cross sectional study. SETTING--Outpatient clinic in teaching hospital, Lusaka, Zambia. PATIENTS--346 Adult patients with tuberculosis. RESULTS--Overall, 206 patients (60%; 95% confidence interval 54% to 65%) were positive for HIV--in one or both assays used. The peaks for both tuberculosis and HIV infection were among men aged 25-34 years and women aged 14-24 years. Of patients with confirmed pulmonary tuberculosis, 73/149 (49%; 41% to 57%) were positive for HIV; 67/83 (81%; 70% to 89%) patients with pleural disease and 16/19 (84%; 60% to 97%) patients with pericardial disease were positive. HIV positive patients with positive sputum culture were less likely to have had a positive sputum smear, and their chest x ray films less often showed classic upper zone disease or cavitation. Of 72 patients who fulfilled clinical criteria for AIDS, 17 were negative for HIV. CONCLUSIONS--The high prevalence of HIV in patients with tuberculosis suggests that an epidemic of reactivating tuberculosis is arising in those who are infected with HIV. The redirection of public health priorities towards tuberculosis would focus on a major treatable and preventable complication of the AIDS epidemic.     

Self-reported confidence, attitudes and skills in practical procedures among medical students: questionnaire study

The aim of our study was to investigate the influence of gender, loss of academic year(s), confidence and attitudes of students on the clinical experience gained by undergraduate education. The survey was conducted during 2004 and 2005 in a sample of 182 students of the 5th and the 6th year at J.J. Strossmayer University School of Medicine in Osijek. The participants were grouped and matched according to their gender, regular studying, the number of time(s) student has performed certain practical medical procedure and the self-confidence arisen by performing one. Furthermore, participants were grouped and compared due to their own assessment of their own practical and theoretical medical knowledge, courses which provide them the least and oppositely--the most practical medical knowledge and their attitude toward current medical faculty curriculum on clinical courses as well as the possibilities of improving them. Fisher's exact test and chi2-test were used to estimate statistical differences between the groups and the parameters in research, while coefficient of contingency was introduced with the aim of defining their correlation. The results showed statistically significant differences between male students who performed more practical medical procedures than female (p < 0.001), non-repeaters performed medical procedures more often than repeaters (p < 0.001, C = 0.658) while repeaters thought higher of their theoretical knowledge than non-repeaters (p < 0.005). Data analysis showed statistically significant correlation between clinical experience and the level of confidence (C = 0.944). This study confirmed influence of male gender, regular studying, better opinion about one's own practical skills and higher confidence in one's own work on greater number of clinical skills performed during undergraduate education.     

The effect of a compulsory curriculum on ethical attitudes of medical students

The purpose of the present study was to assess the influence of a compulsory curriculum on first-year medical students. The ethical attitude study was performed at the School of Medicine, University of Rijeka, Croatia. The samples consisted of 171 medical students (68 males and 103 females) interviewed at the beginning of the first year of studies. Some of them, namely 143 (56 males and 87 females) were interviewed again at the end of the same academic year. Data were analysed by applying factor analysis under principal component model and varimax criterion as the rotation model. The results clearly show that the current compulsory curriculum without formal ethical education has a limited influence on first-year medical students. That points to the obvious necessity to implement the medical ethics in the course of medical education.     

Deficient colour vision and interpretation of histopathology slides: cross sectional study.

OBJECTIVE: To determine whether histopathologists with deficient colour vision make more errors in slide interpretation than those with normal colour vision. DESIGN: Examination of projected transparencies of histopathological slides under standardised conditions by subjects whose colour discriminating ability was accurately assessed. SETTING: Departments of histopathology in 45 hospitals in the United Kingdom. SUBJECTS: 270 male histopathologists and medical laboratory scientific officers. MAIN OUTCOME MEASURES: Number of slides correctly identified by subjects whose colour vision was measured on the Ishihara, City University, and Farnsworth-Munsell 100 hue tests. RESULTS: Mean (SD) scores (out of 10) for doctors with colour deficient vision were 9.4 (0.7) v 9.9 (0.4) for controls (P < 0.01) and 7.5 (1.6) v 9.4 (0.7) for scientific officers (P < 0.001). When subjects with colour deficient vision were categorised into severe, moderate, or mild, there was a significant trend towards those with severe deficiency making more mistakes (P < 0.001). CONCLUSIONS: Histopathologists and medical laboratory scientific officers should have their colour vision tested; if they are found to have a severe protan or deutan deficiency, they should be advised to adopt a safe system of working.     

Reliability of distance estimation by doctors and patients: cross sectional study.

OBJECTIVE: To assess the reliability and accuracy of distance estimated by doctors and patients. DESIGN: Comparison between estimated and measured distances of six familiar sites around Guy''s Hospital, London. SUBJECTS: 100 hospital consultants and 100 patients. MAIN OUTCOME MEASURES: Median (range) of estimated distances, and mean (SD) of the difference between estimated and measured distances. RESULTS: Both doctors and patients gave a wide range of estimates of distance. The estimates differed by up to 14.6-fold from the measured distances, and the difference between minimum and maximum estimates was up to 62.5-fold. CONCLUSION: Doctors and patients were inaccurate at estimating distances, which implies that estimates of distances walked are not reliable indicators of a person''s health.     

Study of smoking habits in hospital and attitudes of medical staff towards smoking.

Most hospital policies place little or no restriction on patients'' smoking in hospital. In this study patients were surveyed to determine if they smoked and if their doctors advised or ordered them to stop smoking in hospital. As well, the smoking habits and attitudes towards smoking of the medical staff and other hospital workers were explored. Of 741 patients 37% were smokers, and those who responded fully to a questionnaire 86% continued to smoke in hospital. Patients who were advised or ordered not to smoke (59%) were no more likely to stop smoking than those who were not so advised or ordered. Physicians were less likely to smoke than other hospital staff, and those who did smoke were much more likely not to smoke while in the hospital. Physicians appear to have a reasonable appreciation of the health hazards of smoking, and almost two thirds are in favour of stricter restrictions on patients'' smoking in hospital. The ineffectiveness of their efforts is primarily due to hospital policies that are not in keeping with physicians'' standards of practice and with established knowledge of the deleterious effects of smoking on health.
