Gambling and gender : A public health perspective

Svensson, Jessika January 2013 (has links)
Prevalence studies around the world show that men are the largest group at risk of becoming problem gamblers and that men gamble more than women. However, gambling research has long been gender blind. The gambling market is rapidly changing, with the Internet making gambling more accessible. Further, despite the well-documented presence of health, social and financial problems among the concerned significant others (CSOs) of someone close with gambling problems in clinical and help-seeking samples, there is little research investigating on this population. This thesis aims to examine the relation between gender and problem gambling among regular gamblers and CSOs, and to determine whether there was a convergence of men’s and women’s gambling behavior between 1997/98 and 2009/10 in Sweden. A further aim is to examine health problems associated with Internet gambling and CSOs. The data collections were taken from three different but linked gambling and health representative national population based studies in Sweden, all using the same methods: telephone interviews supplemented by questionnaires. The studies are as follows: 1) prevalence study 1997/98, age 15-74 years, n = 10,000, response rate 72% (n = 7,139) 2) prevalence study 2008/09, age 16-84 years, n = 15,000, response rate 63% (n = 8,165); and 3) incident study 2009/10, the 8,165 participants from the 2008/09 prevalence study were contacted again, response rate 74% (n = 6,021). Gambling was generally merged into domains based on the axis chance-strategy and public-domestic. The dichotomy of public and private spheres is relevant in since there is a link between the public sphere and notions of masculinity and a link between the private and femininity. Further, the literature suggests that men are attracted to gambling that involves features of strategy, whereas women generally prefer game of chance. Problem gambling was measured using SOGS-R and PGSI. Health variables included measures such as self-reported health, psychological stress, social support, alcohol consumption, and financial situation as a determinant of health. There were very few indications of a convergence between men’s and women’s gambling behavior. Men and women generally gambled in different domains. Men gambled more than women and dominated all domains except the domain of chance-domestic, a domain associated with less risk and Internet gambling. However, men and women who gambled regularly were just as likely to be problem gamblers. No gender differences were found in the score from separate PGSI analyses in the chance-public domain (games of chance in public spaces, such as gambling machines and bingo in halls). This domain was also the only domain associated with problem gambling for women who gambled regularly. Men and women were just as likely to report that they were CSOs and they constituted a large proportion of the Swedish population (18%). CSOs experienced a range of social, economic and health related problems including psychological stress, risky alcohol consumption, exposure to violence, and separations. For women who were CSOs, no relation with own problem gambling was found. This thesis suggests that the presence of gambling machines must be addressed to prevent problem gambling and that separate analyses for men and women are required to identify important differences between genders. The findings indicate that gambling domains produce and reinforce gender. Further, to be able to prevent problem gambling we require further knowledge about these gendered processes. However, it is also important to see the overall similarities between men and women to avoid reinforcing stereotypical images of gender which would have an negative impact on the preventive work. Male and female gamblers are both very heterogeneous categories where the specific gambling site, context and life circumstances must be acknowledged. Prevention, research and interventions should also target CSOs if a public health approach is applied because they require help and support in their own right. CSOs also play an important to the problem gambler. More qualitative research is required to understand gendered processes in gambling, as well as further research on interventions that go beyond the individual and address gambling and problem gambling at various levels. When addressing the harmful effects of gambling from a public health perspective, it is imperative to recognize the ethical principles of justice, autonomy, doing no harm and beneficence. / -

Prostate cancer : epidemiological studies

Grönberg, Henrik January 1995 (has links)
Prostate cancer is a large and increasing medical problem both in Sweden and in the rest of the developed world, with about 300.000 new cases diagnosed world wide annually. Despite the high incidence of this disease, little is known about the aetiology of prostate cancer. The aim of this study was to try to understand more about the natural history and to find possible a etiological risk factors for this tumour. In a population based study of prostate cancer cases in northern Sweden it was found that the large increase in prostate cancer during the last two decades was mainly caused by well (Gl) and moderately (G2) differentiated tumours. However, the incidence of poorly differentiated (G3) tumours remained unchanged. The introduction of new diagnostic methods is the most plausible explanation for the increase of these low grade tumours. The relative survival in prostate cancer was found to be independent of patient age at diagnosis, indicating that tumour proliferation and the aggressiveness of this disease is equal in all ages. However, due to the increasing occurrence of concurrent diseases with growing age the number of lost years caused by prostate cancer decreases dramatically in older age groups. The overall cause specific mortality for prostate cancer was found to be around 50%. In accordance with most other cancer tumours, the annual mortality rate decreased with longer survival also for prostate cancer patients. In a study from the Swedish Twin Register it was found that the proband concordance rates for prostate cancer were 4,5 time greater among monozygotic compared to dizygotic twins. In a large nation-wide cohort study of men who had a father with prostate cancer, the overall standardised incidence ratio (SIR) was 1.70 for prostate cancer. Younger age at diagnosis among the fathers were associated with an increased risk among sons. This cohort study and the twin study indicates that both inherited and familial factors are of importance in a subgroup of prostate cancer patients. In a prospective case-control study, both a high body mass index (BMI) and a high food intake were found to be independent risk factors for prostate cancer. Both BMI and a high food intake might be indicators of a high fat diet, which so far is the most consistent exogenous risk factor for prostate cancer. The use of tobacco or alcoholic beverages were not associated with prostate cancer risk. / <p>Härtill 5 uppsatser</p> / digitalisering@umu

Streptococcus pneumoniae : epidemiological, clinical and serological studies

Burman, Lars Å. January 1993 (has links)
A retrospective study of invasive pneumococcal disease in patients from Greater Göteborg in 1964- 1980 identified 125 cases of meningitis, 305 of pneumonia, 61 of septicemia with unknown focus, and 17 with other manifestations, all verified by cultures from normally sterile body fluids. The incidence was several times higher in infants and in the elderly than in any other age-group. A wide variety of underlying conditions were present in 23% of the infants, 34% of the children, and 81% of the adults. In adults alcoholism was known in one third of the cases. The case fatality rate was 24% among patients with underlying conditions and 9% among previously healthy individuals. The case fatality rate was 50% in patients with hospital-acquired infection. Twohundred-fifteen pneumococcal strains, isolated from blood or CSF from 1971 to 1983 at the laboratories of clinical bacteriology of Göteborg, Malmö, and Umeå were serotyped by coagglutination (COA). Of all isolates, 89% belonged to serotypes represented in the 23-valent vaccine. In a separate study COA was compared with counterimmunoelectrophoresis (CIE). COA was found to have several advantages; rapidity, lower cost, and ability to disclose serotypes with neutral charge, which constituted 19% of all strains. In a prospective study the etiology was determined in 196 hospitalized patients with pneumonia, most of them community-acquired. Culture of specimens from blood, transtracheal aspirate (TTA), sputum, and nasopharynx, assays of antigen in sputum, urine, and TTA, and assays of pneumococcal antibodies to capsular polysaccharide, C-polysaccharide, and pneumolysin in paired sera were performed. The etiology was established in 64% of the patients. Streptococcus pneumoniae was the most common agent (32%). In a serological study of patients with pneumococcal infection, diagnosed by culture of CSF, TTA, or blood, IgG antibodies against C-polysaccharide and pneumolysin were determined by ELISA. The diagnostic sensitivity was only 51% and 60%, respectively. In conclusion, invasive pneumococcal disease is strongly overrepresented at tender and high age and in patients with concomitant conditions, notably alcoholism. S. pneumoniae remains a predominant causative agent of community-acquired pneumonia in adults needing hospitalization. Due to the low sensitivity and/or specificity of individual microbiological techniques, a combined use of several techniques is necessary when trying to assess the relative importance of pneumococci and other agents in pneumonia. Extended use of the currently available pneumococcal vaccine and development of improved pneumococcal vaccines seem highly warranted. / <p>Diss.

The MARS pilot project: implementing real-time measles and rubella surveillance during elimination phase in Canada

EisBrenner, Tracie 14 January 2014 (has links)
OBJECTIVES: Measles and rubella are nationally notifiable, vaccine-preventable diseases targeted for elimination by the Pan American Health Organization (PAHO). To support national and international elimination efforts, surveillance optimization is important to ensure rapid case detection, document endemic transmission interruption, identify susceptible populations and inform immunization strategies. While current national surveillance captures confirmed-case data, its performance cannot be assessed using PAHO-recommended surveillance indicators as suspect-case investigation data are required for their estimation. In Canada, the investigation of clinically-suspect measles-like illness (MLI) is highly dependent on laboratory evidence, providing an opportunity to use laboratory data to estimate MLI investigation rates. The Measles and Rubella Surveillance (MARS) pilot project was developed to address existing surveillance challenges with the central hypothesis that (I) ‘it is feasible to develop and implement a real‐time, web‐based measles and rubella surveillance system in the Canadian setting’, and the following sub‐hypotheses: (II) ‘implementation of real‐time surveillance in MARS pilot provinces will result in increased timeliness of national measles and rubella surveillance when compared with established confirmed-case surveillance’, and (III) ‘it is possible to use augmented laboratory data to estimate the performance of national measles and rubella surveillance using adapted PAHO indicators’. METHODS: A MARS application was designed to support centralized real-time measles/ rubella investigation reporting and alerting with integration of non-nominal laboratory and epidemiological data, then developed and piloted using the web-based Canadian Network for Public Health Intelligence platform in British Columbia, Alberta and Newfoundland from June/2011-May/2012. Pre- and post-pilot laboratory surveys were conducted to retrospectively assess national surveillance performance in ‘outbreak’ and ‘non-outbreak’ settings during the 2005‐2011 and pilot years using various surveillance indicators and attributes. Measles IgM serology testing was used as a laboratory-based proxy for MLI investigation to support indicator estimation. RESULTS: Real-time, integrated surveillance was successfully implemented in MARS pilot provinces as modeled within the context of established reporting roles, and surveillance indicators and attributes were estimated using augmented laboratory data. MARS surveillance was more timely than confirmed-case surveillance, and real-time MARS reports exceeded all laboratory-related PAHO targets evaluated: 100% met ‘sample collection’ and ‘receipt’ timelines, and 91.7% met ‘result' timelines (Targets:≥80%); 99.8% of all MLI investigations were discarded (Target:≥95%). A national ‘non-outbreak’ baseline rate of 14 MLI investigations/100 000 population was estimated, whereas MARS pilot sites averaged 22 MLI investigations/100 000 population during the pilot year. While ‘non-outbreak’ investigation rates varied between provinces, all annual provincial and national rates estimated for the 2005‐2011 and MARS pilot years exceeded the PAHO investigation target of ≥2 suspected cases/100 000 population in settings attempting elimination. CONCLUSIONS: The MARS model supported more timely and integrated national measles and rubella surveillance, and enabled indicator‐based performance assessment. Results underscore the importance of laboratory data when evaluating and documenting surveillance performance to support elimination efforts. Consideration should be given to national MARS implementation and its use as a model adaptable to the case-based surveillance of other nationally notifiable diseases.

Epidermiology and Treatment of Tuberculosis in Liepaja (Latvia) 1993-2002

Kužniece, Ingrida January 2006 (has links)
Aim To describe the epidemiology of tuberculosis in the city of Liepaja during the last 27 years and the management of patients with tuberculosis during the period 1993-2002; to identify problems in tuberculosis management relevant to increasing level of morbidity and the registered high levels of drug-resistance. Material and methods The cases were all persons reported with tuberculosis in 1975-2002. The data sources were the yearly Health Statistics books at the Latvian Office of Medical Statistics. The study used data from the available 655 individual patient records from Liepaja Tuberculosis Dispensery and TB Register of 1993 – 2002. Information was extracted selectively and extraction sheets containing the variables of interest were developed. The incidence differences according to sex and age, possible clustering of patients in high-risk living areas of the city, differences in occupation of the patients were studied. The differences of time from disease symptoms to diagnosis, as well as investigation data, treatment regimens, the proportions of treatment outcomes were analysed. Analysis was done using EPI-INFO programme for statistical analysis. Results In the 1980s tuberculosis was under control in Latvia and the incidence was at the European average level. After Latvia had regained independence in 1991, with economical and political disruption and changes in the health care system, TB incidence and mortality in the country increased rapidly as well as in Liepaja. Although not very high compared to global TB rates, there was great concern about TB control in Latvia. In addition, the emergence of drug resistance and multi-drug resistant bacteria made the TB epidemic more serious. The TB incidence increase in children suggested that there was quite a big number of undetected cases of TB. Tuberculosis control and early detection activities were not integrated into the PHC system. Treatment results of TB were quite poor and showed high proportions of interruptions, defaults, relapses. The tuberculosis control Programme in Latvia and Liepaja put much effort into the improvement of the epidemiological situation with TB, focusing on TB control activities and management during the period 1993-2002. The incidence of tuberculosis in Liepaja was higher than in Latvia, particularly in some living areas in the city, and above endemic level. Mortality rate in average was higher as in the whole country. The proportion of socially sensitive groups (children, unemployed, pensioners, disabled) comprised more than 50 % of the tuberculosis incidence. Incidence among medical staff was higher than in general population in the all professional groups. Medical delay of diagnosis decreased, but early detection of tuberculosis was not fully integrated in PHC system. There were quite big differences in numbers of MDR-TB in years 1993-2002. DOTS was introduced in Liepaja five years later than in Latvia –in year 2000 and strategy was not fully successful. The number of positive treatment outcomes increased, but the registered numbers of treatment relapses and defaults were higher than in Latvia . Conclusions The situation with regard to tuberculosis development and tuberculosis management in Liepaja during the period under study was unfavourable. Particularly : the incidence and mortality rates, much variation in the diagnostic process, results of treatment ,a high proportion of MDR-TB , unsatisfactory links between local government, family doctors and medical professionals and multi-sectoral collaboration in TB control activities , the objectives set up by WHO for DOTS treatment were not reached / <p>ISBN 91-7997-139-3</p>

The Inflammatory Bowel Disease Cohort of the Uppsala Region (ICURE) : Epidemiology and Complications

Sjöberg, Daniel January 2015 (has links)
The overall aims of this thesis were to investigate the incidence of inflammatory bowel disease in the Uppsala Region of Sweden, to study the clinical course and the impact of the disease with regards to complications. Patients in Uppsala County were included in the study from the 1st of January 2005 and patients in Falun, Eskilstuna and Åland counties from the 1st of January 2007. The study was closed for all centres on the 31st of December 2009. Mean population in the study region was 305,381 in 2005–2006 and 642,117 in 2007–2009. The mean incidence for ulcerative colitis (UC) during the time period 2005-2009 was 20.0 /100,000/year (95% CI: 16.1-23.9) and for Crohn’s disease (CD) it was 9.9/100,000/year (95% CI: 7.1-12.6). The combined incidence for UC or CD in the area was thus 29.9/100,000/year (95% CI: 25.1-34.7). Half of the UC patients relapsed during the first year. Risk factors for relapse were female gender and young age. Colectomy during the first year was uncommon (2.5%). CD patients with complicated disease had longer symptom duration before diagnosis and less often diarrhoea and blood in stools compared to patients with non-complicated disease. The risk for surgery during the first year was 12%. The prevalence of anaemia at the time of diagnosis was 30% and after one year 18%. Anaemia was more common among newly diagnosed patients with CD compared with UC. 13% of the UC patients developed an acute severe episode. During the first 90 days 22% of these patients were subjected to colectomy. There was a significant difference between University and County hospitals in colectomy frequency (7.5% vs. 41%). The cumulative prevalence of treatment complications was 12% at the hospital with low colectomy rate versus 41% at the hospitals with high colectomy rate. In conclusion, the incidence of UC and CD in Sweden was high compared to international studies. Colectomy frequency for UC during the first year was low. Patients with complicated CD at the time of diagnosis had longer symptom duration and less alarming symptoms compared to uncomplicated disease. Anaemia was a common trait among patients with newly diagnosed IBD and more effort is needed to treat anaemia in these patients. Severe UC can be treated safely with prolonged medical therapy instead of colectomy.
