Poverty, time, and place: variation in excess mortality across selected US populations, 1980-1990.
(73/7064)
STUDY OBJECTIVE: To describe variation in levels and causes of excess mortality and temporal mortality change among young and middle aged adults in a regionally diverse set of poor local populations in the USA. DESIGN: Using standard demographic techniques, death certificate and census data were analysed to make sex specific population level estimates of 1980 and 1990 death rates for residents of selected areas of concentrated poverty. For comparison, data for whites and blacks nationwide were analysed. SETTING: African American communities in Harlem, Central City Detroit, Chicago's south side, the Louisiana Delta, the Black Belt region of Alabama, and Eastern North Carolina. Non-Hispanic white communities in Cleveland, Detroit, Appalachian Kentucky, South Central Louisiana, Northeastern Alabama, and Western North Carolina. PARTICIPANTS: All black residents or all white residents of each specific community and in the nation, 1979-1981 and 1989-1991. MAIN RESULTS: Substantial variability exists in levels, trends, and causes of excess mortality in poor populations across localities. African American residents of urban/northern communities suffer extremely high and growing rates of excess mortality. Rural residents exhibit an important mortality advantage that widens over the decade. Homicide deaths contribute little to the rise in excess mortality, nor do AIDS deaths contribute outside of specific localities. Deaths attributable to circulatory disease are the leading cause of excess mortality in most locations. CONCLUSIONS: Important differences exist among persistently impoverished populations in the degree to which their poverty translates into excess mortality. Social epidemiological inquiry and health promotion initiatives should be attentive to local conditions. The severely disadvantageous mortality profiles experienced by urban African Americans relative to the rural poor and to national averages call for understanding. (+info)
How good is the Prevent model for estimating the health benefits of prevention?
(74/7064)
STUDY OBJECTIVE: Prevent is a public health model for estimating the effect on mortality of changes in exposure to risk factors. When the model is tested by simulating a development that has already taken place, the results may differ considerably from the actual situation. The purpose of this study is to test the Prevent model by applying it to a synthetic cohort in which the development is unaffected by concealed factors. DESIGN: A micro-simulation model was developed to create basic data for Prevent and give "exact" results as to changes in risk factor prevalences and mortality. The estimates of Prevent simulations were compared with the "exact" results. MAIN RESULTS: Modelling one risk factor related to a cause specific mortality gave fairly similar results by the two methods. Including two risk factors Prevent tends slightly to overestimate the health benefits of prevention. CONCLUSIONS: The differences between the "exact" mortality and the Prevent estimates will be small for realistic scenarios and Prevent provide reasonable estimates of the health benefits of prevention.

Nutritional counselling in general practice: a cost effective analysis.
(75/7064)
STUDY OBJECTIVE: To study the clinical and cost outcomes of providing nutritional counselling to patients with one or more of the following conditions: overweight, hypertension and type 2 diabetes. DESIGN: The study was designed as a random controlled trial. Consecutive patients were screened opportunistically for one or more of the above conditions and randomly allocated to one of two intervention groups (doctor/dietitian or dietitian) or a control group. Both intervention groups received six counselling sessions over 12 months from a dietitian. However, in the doctor/dietitian group it was the doctor and not the dietitian who invited the patient to join the study and the same doctor also reviewed progress at two of the six counselling sessions. SETTING: The study was conducted in a university group general practice set in a lower socioeconomic outer suburb of Perth, Western Australia. PATIENTS: Of the 273 patients randomly allocated to a study group, 198 were women. Age ranged from 25 to 65 years. Seventy eight per cent of patients resided in the lower two socioecnomic quartiles, 56 per cent described their occupation as home duties and 78 per cent were partnered. RESULTS: Both intervention groups reduced weight and blood pressure compared with the control group. Patients in the doctor/dietitian group were more likely to complete the 12 month programme than those in the dietitian group. Patients in the doctor/dietitian group lost an average of 6.7 kg at a cost of $A9.76 per kilogram, while the dietitian group lost 5.6 kg at a cost of $A7.30 per kilogram. CONCLUSION: General practitioners, in conjunction with a dietitian, can produce significant weight and blood pressure improvement by health promotion methods. (+info)
Shifting the distribution of risk: results of a community intervention in a Swedish programme for the prevention of cardiovascular disease.
(76/7064)
STUDY OBJECTIVE: To examine the impact of a systematic risk factor screening and counselling carried out by family physicians and family nurses within the larger framework of a community intervention programme for the prevention of cardiovascular disease (CVD). DESIGN: Quasi-experimental study comparing trends in an intervention area with those in a reference area. SETTING: A Northern Sweden municipality (5500 inhabitants) constituted the intervention area while the Northern Sweden region (510,000 inhabitants) served as the reference area. PARTICIPANTS: All 30, 40, 50, and 60 year old inhabitants were invited each year from 1985 to 1992. Among 2046 eligible 1893 participated (92.5%), which formed eight independent cross sections. One cross section, 1986, was re-surveyed forming a panel. MAIN RESULTS: In the cross sections, mean total cholesterol was reduced from 7.09 to 6.27 mmol/l for men (p < 0.001) and from 7.13 to 5.89 mmol/l for women (p < 0.001) and mean systolic blood pressure from 132.2 to 123.7 mm Hg for men (p < 0.05) and from 129.2 to 122.0 mm Hg for women (p < 0.001) during the eight years. Body mass index (BMI) increased from 25.6 to 26.2 for men (p < 0.05) and from 25.0 to 25.5 for women (NS). A corresponding reduction in cholesterol and blood pressure (for women) occurred in the panel, while BMI was unchanged. The risk for CVD, using the Framingham equation, was estimated to be reduced overall by 19% (p = 0.0021) when comparing early cross sections (1985/86) with the later cross sections (1990/91). CONCLUSIONS: It was concluded that a long term community based CVD prevention programme that combines population and individual strategies can substantially promote a health shift in CVD risk in a high risk rural population. The individual attention and evaluation provided by the health provider survey seem to accelerate, but not increase the amount of, risk reduction. (+info)
Towards a secure evidence base for health promotion.
(77/7064)
The importance of a sound evidence base for health promotion is recognized. Criteria for establishing evidence have, in the past, been heavily influenced by the bio-medical agenda. The problems in using experimental and quasi-experimental approaches and their limited relevance for evaluating health promotion interventions are examined. The multifactorial nature of the health promotion enterprise in relation to both inputs and outputs is recognized and a range of direct, indirect and process indicators are identified. The relevance of combining quantitative and qualitative methods for data collection is discussed and the paper concludes by advocating a 'judicial principle' for assessing evidence. (+info)
Health promoting schools in England--a way forward in development.
(78/7064)
Schools are identified as a key setting for health promotion in the UK Government's consultation report on the public health strategy for England. The concept of the 'healthy' or 'health promoting school' provides the basis for a broad settings approach to health promotion in schools. The approach extends beyond the formal health education curriculum to include a consideration of the physical and social environment of schools and their links and partnerships with parents and the wider community, in pursuit of better health. There is growing evidence that the health promoting school approach is effective in influencing outcomes related to health and education. Initiatives in the form of projects and schemes are commonly used by Health Promotion Specialist services and health partnerships, to stimulate and support the adoption of the approach by schools. A national healthy school scheme is to be launched alongside these local initiatives in 1999. The paper reviews research and practice in this area and makes recommendations to inform the future development of schools as health promoting organizations. (+info)
Status of health promotion programme implementation in small-scale enterprises in Japan.
(79/7064)
This study was conducted to determine the status of the implementation of health promotion programmes (HPPs) in Japanese small-scale enterprises (SSEs). A survey was conducted in 1996 using a questionnaire mailed to all the member construction companies (n = 772) of a health insurance society, and a response rate of 84% was obtained. Health examination was most frequently conducted (90%), followed by exercise/fitness programmes (17%), smoking measures (12%), health guidance (11%) and nutrition education (6%). Mental health programmes and the government-advocated Total Health Promotion Plan (THP) were implemented at less than 2% of SSEs. The implementation rates for these programmes, except for smoking measures and the THP, were higher at large enterprises than at SSEs. The employment rate for occupational physicians (OPs) was 9% and 49% at SSEs and large enterprises, respectively. The activity most frequently conducted by OPs was health examination, followed by curative services and health education. Advising employees to undergo re-examination or more valid examination after the annual health examination was most frequently conducted by non-health professionals. (+info)
A health promotion programme for oil refinery employees: changes of health promotion needs observed at three years.
(80/7064)
The main aim of this three-year follow-up study was to evaluate the long-term effects of a workplace health promotion intervention programme offered by the Neste Oyj corporation's occupational health service. Another aim was to study factors associated with changes in health promotion needs. These were assessed using information obtained by means of questionnaires and laboratory measurements. The target areas assessed were physical activity, musculoskeletal problems, dietary habits, obesity, blood pressure, serum lipids, smoking, quality of sleep and mental well-being. Participants from one oil refinery were offered special health promotion counselling, while those from the other oil refinery studied received only their personal results, written information and instructions. Evaluation of the changes in needs was mainly based on comparison of the results of two examinations performed with an interval of three years. Effects of special health promotion counselling were observed in the target area of physical activity. Elimination of certain health promotion needs was seen in both groups in all of the target areas. The most extensive changes were seen in the target areas of musculoskeletal symptoms, dietary habits, blood pressure and mental well-being. Basic education, occupational status and age-group, as well as the value of tending health were frequent variables explaining the reduction in the need for health promotion activities. Worker participation in health promotion counselling activities provided by occupational health services can be high, as in this study in which the participation rate was 90% and the drop-out rate during the three years only 10%.
