(1/5270) Geographic, demographic, and socioeconomic variations in the investigation and management of coronary heart disease in Scotland.

OBJECTIVE: To determine whether age, sex, level of deprivation, and area of residence affect the likelihood of investigation and treatment of patients with coronary heart disease. DESIGN, PATIENTS, AND INTERVENTIONS: Routine discharge data were used to identify patients admitted with acute myocardial infarction (AMI) between 1991 and 1993 inclusive. Record linkage provided the proportion undergoing angiography, percutaneous transluminal coronary angioplasty (PTCA), and coronary artery bypass grafting (CABG) over the following two years. Multiple logistic regression analysis was used to determine whether age, sex, deprivation, and area of residence were independently associated with progression to investigation and revascularisation. SETTING: Mainland Scotland 1991 to 1995 inclusive. MAIN OUTCOME MEASURES: Two year incidence of angiography, PTCA, and CABG. Results-36 838 patients were admitted with AMI. 4831 (13%) underwent angiography, 587 (2%) PTCA, and 1825 (5%) CABG. Women were significantly less likely to undergo angiography (p < 0.001) and CABG (p < 0.001) but more likely to undergo PTCA (p < 0.05). Older patients were less likely to undergo all three procedures (p < 0.001). Socioeconomic deprivation was associated with a reduced likelihood of both angiography and CABG (p < 0.001). There were significant geographic variations in all three modalities (p < 0.001). CONCLUSION: Variations in investigation and management were demonstrated by age, sex, geography, and socioeconomic deprivation. These are unlikely to be accounted for by differences in need; differences in clinical practice are, therefore, likely.  (+info)

(2/5270) Identifying families with likely genetic protective factors against Alzheimer disease.

Elderly individuals who lived beyond the age of 90 years without dementia were hypothesized to have increased concentrations of genetic protective factors against Alzheimer disease (AD), conferring a reduced liability for this disease relative to less-aged nondemented elderly. However, testing this hypothesis is complicated by having to distinguish such a group from those who may lack genetic risk factors for AD, have had protective environmental exposures, or have escaped dementia for other reasons. Probands carrying genetic protective factors, however, should have relatives with lower illness rates not only for earlier-onset disease, when genetic risk factors are a strong contributing factor to the incidence of AD, but also for later-onset disease, when the role of these factors appears to be markedly diminished. AD dementia was assessed through family informants in 6,660 first-degree relatives of 1,049 nondemented probands aged 60-102 years. The probands were grouped by age (60-74, 75-89, and 90-102 years), and the cumulative survival from AD and 10-year-age-interval hazard rates of AD were calculated in their first-degree relatives. Cumulative survival from AD was significantly greater in the relatives of the oldest proband group (aged 90-102 years) than it was in the two younger groups. In addition, the reduction in the rate of illness for this group was relatively constant across the entire late life span. The results suggest that genetic factors conferring a lifelong reduced liability of AD may be more highly concentrated among nondemented probands aged >/=90 years and their relatives. Efforts to identify protective allele-bearing genes that are associated with very late-onset AD should target the families of nonagenarians and centenarians.  (+info)

(3/5270) Tay-Sachs screening: motives for participating and knowledge of genetics and probability.

A highly-educated, socially aware group of persons presented themselves for Tay-Sachs screening having learned about it mainly from friends, newspapers, radio, and television but not from physicians or rabbis. After learning that screening was possible and deciding that it is in principle a good idea, and after discussing it with relatives and friends but not with physicians and rabbis, they presented themselves for the test. Although the participants knew that Tay-Sachs is a serious disease and that Jews are vulnerable, few of them knew much about the genetics of the disease, its frequency, or the incidence of the carrier state. This experience of screening for Tay-Sachs carriers suggests the need for physicians to learn the relation of genetics to preventive medicine, and for the public to learn more about the biology of man.  (+info)

(4/5270) Disease patterns of the homeless in Tokyo.

In recent years, homelessness has been recognized as a growing urban social problem in various countries throughout the world. The health problems of the homeless are considerable. The purpose of this study was to elicit, with sociodemographic profiles, the disease patterns among Tokyo's homeless. The subjects were 1,938 men who stayed at a welfare institution from 1992 to 1996. Diagnosed diseases/injuries and sociodemographic profiles were analyzed. The disease patterns of the homeless were compared to those of the male general population. Of the subjects, 8.3% were admitted to the hospital; 64.0% received outpatient care. Their observed morbidity rates by disease category were greater than those of the male general population in both Japan and Tokyo. Comorbidity of alcoholic psychosis/alcohol-dependent syndrome to both liver disease and pulmonary tuberculosis were greater than the average (P < .01). Construction work brought a higher risk of pulmonary tuberculosis (odds ratio = 2.0) and dorsopathies (odds ratio = 1.4) than did other jobs (P < .05). Disease patterns among the homeless in Tokyo were characterized by alcoholic psychosis/alcohol-dependence syndrome; liver disease; pulmonary tuberculosis; diabetes mellitus; fractures, dislocations, sprains, strains; hypertension; and cerebrovascular disease. Although the sociodemographic backgrounds of Tokyo's homeless have become more diverse, the principal occupation of the homeless was unskilled daily construction work, which underlay the characteristics of their disease patterns.  (+info)

(5/5270) Marijuana use among minority youths living in public housing developments.

Youths residing in public housing developments appear to be at markedly heightened risk for drug use because of their constant exposure to violence, poverty, and drug-related activity. The purpose of this study was to develop and test a model of marijuana etiology with adolescents (N = 624) residing in public housing. African-American and Hispanic seventh graders completed questionnaires about their marijuana use, social influences to smoke marijuana, and sociodemographic and psychosocial characteristics. Results indicated that social influences, such as friends' marijuana use and perceived ease of availability of marijuana, significantly predicted both occasional and future use of marijuana. Individual characteristics such as antimarijuana attitudes and drug refusal skills also predicted marijuana use. The findings imply that effective prevention approaches that target urban youths residing in public housing developments should provide them with an awareness of social influences to use marijuana, correct misperceptions about the prevalence of marijuana smoking, and train adolescents in relevant psychosocial skills.  (+info)

(6/5270) Is choice of general practitioner important for patients having coronary artery investigations?

OBJECTIVE: To determine whether particular sociodemographic characteristics of patients with stable angina affected their general practitioners' (GPs') decisions to refer them for revascularisation assessment. DESIGN: Postal questionnaire survey. SETTING: Collaborative survey by the departments of public health medicine in each of the four health boards in Northern Ireland, serving a total population of 1.5 million. SUBJECTS: All (962) GPs. MAIN MEASURES: The relation between GPs' referral decisions and patients' age, sex, employment status, home circumstances, smoking habits, and obesity. RESULTS: 541 GPs replied (response rate 56%). Most were "neutral" towards a patient's sex (428, 79%), weight (331, 61%), smoking habit (302, 56%), employment status (431, 80%), and home circumstances (408, 75%) in making decisions about referral. In assigning priority for surgery most were neutral towards the patient's sex (459, 85%), employment status (378, 70%), and home circumstances (295, 55%). However, most GPs (518, 95%) said that younger patients were more likely to be referred, and a significant minority were less likely to refer patients who smoked (202, 37%) and obese patients (175, 32%) and more likely to refer employed patients (97, 18%) and those with dependents (117, 22%) (compared with patients with otherwise comparable clinical characteristics); these views paralleled the priority which GPs assigned these groups. The stated likelihood of referral of young patients was independent of the GPs' belief in ability to benefit from revascularisation, but propensity to refer and perception of benefit were significantly associated for all other patient characteristics. CONCLUSION: GPs' weighting of certain characteristics in reaching decisions about referral for angiography is not uniform and may contribute to unequal access to revascularisation services for certain patient groups.  (+info)

(7/5270) Factors influencing default at a hospital colposcopy clinic.

OBJECTIVE: To identify factors reducing compliance at diagnosis, treatment, and review stages among women referred with abnormal cervical smears to a hospital colposcopy clinic. DESIGN: Retrospective analysis of sociodemographic data from hospital notes of the attenders and defaulters during one year (1989-90) and prospective collection of information by structured interviews of a sample of defaulters and attenders during five months (May-September 1990). SETTING: One hospital colposcopy clinic. PATIENTS: 238 women defaulting on two consecutive occasions and 188 attending regularly (retrospective analysis) and a subset of 40 defaulters and 24 attenders (interview sample). MAIN MEASURES: Sociodemographic data and interview responses about attitudes, behaviour, choice, accessibility cultural understanding, communications, and emotional response. RESULTS: 22 (12%) women defaulted at diagnosis, 24(13%) at treatment, 39(21%) at the first check up after treatment, and 84(45%) at the review stage; 19(10%) defaulted from the first check up after diagnostic examination revealed no need for treatment. Age and social class differed between the two groups. 181(76%) defaulters were under 30 compared with 91(48%) attenders; 14(6%) compared with 41(23%) were over 40(p < 0.001). The proportion of women in social classes 4 and 5 was 33%(20/60) for defaulters and 21%(25/120) for attenders (p < 0.05) and unemployed was 66%(158/238) and 36%(68/188) respectively. 63(28%) defaulters were pregnant compared with 11(6%) attenders (p < 0.001). More defaulters came from gynaecology or antenatal clinics. Most defaulters (93%) had child care responsibilities and they knew and understood less about colposcopy. Their explicit reasons for defaulting included child care commitments and fear and their implicit reasons lack of understanding, inaccessibility of information, and staff attitudes. CONCLUSIONS: Compliance may be improved by promoting women's understanding of treatment and encouraging health professionals to develop a service more sensitive to the various needs of women in different socioeconomic groups.  (+info)

(8/5270) The determinants of infant and child mortality in Tanzania.

This paper investigates the determinants of infant and child mortality in Tanzania using the 1991/92 Tanzania Demographic and Health Survey. A hazards model is used to assess the relative effect of the variables hypothesized to influence under-five mortality. Short birth intervals, teenage pregnancies and previous child deaths are associated with increased risk of death. The Government of the United Republic of Tanzania should therefore maintain its commitment to encouraging women to space their births at least two years apart and delay childbearing beyond the teenage years. Further, this study shows that there is a remarkable lack of infant and child mortality differentials by socioeconomic subgroups of the population, which may reflect post-independence health policy and development strategies. Whilst lack of socioeconomic differentials can be considered an achievement of government policies, mortality remains high so there is still a long way to go before Tanzania achieves its stated goal of 'Health for All'.  (+info)
