The Newcastle exercise project: a randomised controlled trial of methods to promote physical activity in primary care.
(57/2788)
OBJECTIVE: To evaluate the effectiveness of combinations of three methods to promote physical activity. DESIGN: Randomised controlled trial. Baseline assessment with post-intervention follow up at 12 weeks and 1 year. SETTING: One urban general practice, 1995-7. PARTICIPANTS: 523 adults aged 40 to 64 years, randomised to four intervention groups and a control group. INTERVENTIONS: Brief (one interview) or intensive (six interviews over 12 weeks) motivational interviewing based on the stages of change model of behaviour change, with or without financial incentive (30 vouchers entitling free access to leisure facilities). MAIN OUTCOME MEASURES: Physical activity score; sessions of moderate and vigorous activity in the preceding four weeks. RESULTS: Response rate was 81% at 12 weeks and 85% at one year. More participants in the intervention group reported increased physical activity scores at 12 weeks than controls (38% v 16%, difference 22%, 95% confidence interval for difference 13% to 32%), with a 55% increase observed in those offered six interviews plus vouchers. Vigorous activity increased in 29% of intervention participants and 11% of controls (difference 18%, 10% to 26%), but differences between the intervention groups were not significant. Short term increases in activity were not sustained, regardless of intensity of intervention. CONCLUSIONS: The most effective intervention for promoting adoption of exercise was the most intensive. Even this did not promote long term adherence to exercise. Brief interventions promoting physical activity that are used by many schemes in the United Kingdom are of questionable effectiveness.

Prevalence and risk of cysticercosis and taeniasis in an urban population of soldiers and their relatives.
(58/2788)
To determine markers of Taenia solium transmission and risk factors in an urban community, we studied 1,000 soldiers from a military camp in Mexico City and their relatives. Serum samples were used to detect antigens and antibodies and fecal specimens were examined for Taenia coproantigens and helminth eggs. Prevalences of 12.2% and 5.8% for cysticercosis were found among soldiers and their relatives, respectively. Taeniasis was found in 0.5% and none of the groups, respectively. Relatives of soldiers positive for cysticercosis and taeniasis markers ate more pork from street stores than restaurants or markets compared with relatives of soldiers without these indicators of infection. Also, 12.0% of the relatives of positive soldiers had a history of expelling tapeworm proglottids in the feces in contrast to 3.7% of the family members of the control group. Prevalence values and risk factors in this urban population are similar to those of previous studies performed in rural populations. (+info)
The behaviour of health workers in an era of cost sharing: Ghana's drug cash and carry system.
(59/2788)
This qualitative study aimed to assess possible changes in prescription patterns and resultant implications for the quality of care delivered in three southern districts of Ghana after the introduction of a full cost recovery scheme for drugs in 1992. While the availability of safe and effective drugs has improved especially in rural areas, not all patients are able to meet the cost for required medication. This has influenced the behaviour of most prescribers, who now take economical limitations into account. As a result, poorer patients may either take fewer drugs or smaller quantities than medically indicated, with possible ensuing consequences for public health. Overall, the cash-and-carry scheme does not appear to have changed health workers' attitudes towards patients; where such behavioural changes occurred they seemed to be due to personnel shortages. Generally, patients in rural facilities reported greater satisfaction with the care they received than urban residents; and medical assistants were perceived as friendlier than both nurses and doctors.

Improving service quality: experience from the Tanzania Family Health Project.
(60/2788)
OBJECTIVE: To improve the quality and uptake of reproductive health service in rural communities in Tanzania. DESIGN: Descriptive study of operational research. SETTING: One and a half million people living in urban and rural communities in the Mbeya Region of Tanzania. METHOD: Design and implementation of a range of service quality improvement measures. INTERVENTIONS: Management systems strengthening; clinical skills training; orientation of health staff to service quality; introduction of quality assurance systems; improvement to supervision systems; community involvement in monitoring health service delivery. OUTCOME MEASURES: Health service utilization rates; client perceptions of health service quality; situation analysis of health service provision. RESULTS: Uptake of reproductive health services increased; improved client perceptions of service quality; improved health infrastructure; increased community participation in health service management. CONCLUSIONS: Health service quality in sub-Saharan Africa can be improved substantially through a process of identifying and addressing the constraints which militate against effective service provision. The cost of such improvement is modest compared with current health expenditure. Health planners and managers involved in sectoral reform programmes should give due attention to quality assurance mechanisms in addition to structural elements of the reform process. (+info)
Smoke alarm installation and function in inner London council housing.
(61/2788)
AIM: To determine the prevalence of and predictors for installed, functioning smoke alarms in council (public) housing in a low income, multi-ethnic urban area. DESIGN: Cross sectional study. SETTING: 40 materially deprived electoral wards in two inner London boroughs. PARTICIPANTS: Occupants of 315 addresses randomly selected from council housing lists, with 75% response rate. MAIN OUTCOME MEASURES: Installation and function of smoke alarms based on inspection and testing. RESULTS: 39% (95% confidence interval (CI) 33% to 46%) of council tenants owned a smoke alarm, 31% (95% CI 25% to 38%) had an installed alarm (of which 54% were correctly installed), and 16% (95% CI 12% to 22%) had at least one installed, functioning alarm. Alarms most commonly failed because they lacked batteries (72%). In multivariate modelling, having an installed, functioning alarm was most strongly associated with living in a house versus a flat (apartment) (odds ratio (OR) 3.2, 95% CI 1.1 to 10.0), having two resident adults versus one (OR 2.8, 95% CI 1.2 to 6.5), and recognising stills from a Home Office television smoke alarm campaign (OR 2.4, 95% CI 1.1 to 5.5). CONCLUSIONS: Fires are a leading cause of child injury and death, particularly among those younger than 5 years of age and those in social classes IV and V. Smoke alarms are associated with a significantly reduced risk of death in residential fires, and are more protective in households with young children. Few council properties in a multi-ethnic, materially deprived urban area had any installed, functioning smoke alarms, despite a high risk of residential fires and fire related injuries in such areas. Effective methods to increase the prevalence of installed and functioning alarms must be identified. (+info)
Ecological study of social fragmentation, poverty, and suicide.
(62/2788)
OBJECTIVES: To investigate the association between suicide and area based measures of deprivation and social fragmentation. DESIGN: Ecological study. SETTING: 633 parliamentary constituencies of Great Britain as defined in 1991. MAIN OUTCOME MEASURES: Age and sex specific mortality rates for suicide and all other causes for 1981-92. RESULTS: Mortality from suicide and all other causes increased with increasing Townsend deprivation score, social fragmentation score, and abstention from voting in all age and sex groups. Suicide mortality was most strongly related to social fragmentation, whereas deaths from other causes were more closely associated with Townsend score. Constituencies with absolute increases in social fragmentation and Townsend scores between 1981 and 1991 tended to have greater increases in suicide rates over the same period. The relation between change in social fragmentation and suicide was largely independent of Townsend score, whereas the association with Townsend score was generally reduced after adjustment for social fragmentation. CONCLUSIONS: Suicide rates are more strongly associated with measures of social fragmentation than with poverty at a constituency level. (+info)
The impact of climate on the prevalence of respiratory tract infections in early childhood in Lahore, Pakistan.
(63/2788)
BACKGROUND: Respiratory tract infections are a major health problem in developing countries. The aim of this study was to analyse the impact of the climate on the prevalence of upper respiratory tract infection (URTI) and lower respiratory tract infection (LRTI) in four socioeconomically different groups in a developing country. METHODS: A prospective cohort study was conducted among children in four socioeconomically different groups in Lahore, Pakistan. Monthly observations were made on 1476 infants born during 1984-1987 and followed for 24 months. Prevalence of URTI and LRTI was analysed according to age, area of living, family size, time of birth, the season of the year and climate variables such as rain, temperature and humidity. RESULTS: Low monthly average minimum day temperature was associated with high prevalence of URTI and LRTI. For LRTI the impact of temperature was larger for boys, children living in larger families and children living in the poorer areas. This pattern was not seen for URTI. A peak in prevalence for LRTI was shown at 5-6 months of age for LRTI and at 10-12 months of age for URTI. CONCLUSIONS: Temperature is related to prevalence of URTI and LRTI in a developing society. The effect of temperature on health varies between different subgroups. These effects should be considered in planning health actions to prevent respiratory tract infections. (+info)
Residual need in orthodontically untreated 16-20-year-olds from areas with different treatment rates.
(64/2788)
Knowledge concerning residual orthodontic need among individuals who have passed the age at which orthodontic treatment is normally provided, is important in the discussion of guidelines for the provision of care. The purpose of the present study was to examine and compare orthodontic need (objective and subjective) in cohorts of orthodontically untreated individuals from areas with various treatment rates. A total of 250 individuals, aged 16-20 years, comprised four samples representing cohorts from areas in Norway with low, medium, and high treatment rates. The occlusion was assessed according to a treatment need index (NOTI) from clinical and radiographic records, and dental cast measurements. Attitudes were assessed from questionnaires addressing satisfaction with dental arrangement, desire for treatment, and value placed upon well-aligned teeth. A significant decrease in occurrence of normative need (P < 0.001) and reported dissatisfaction (P < 0.05) was observed in samples representing increasing treatment rates. Dissatisfaction was completely eliminated among individuals from the high treatment rate area. Although a significant association between severity of malocclusion and desire for treatment existed within samples, this was not reflected in a corresponding trend for a decrease in desire across the samples. Well-aligned teeth seemed to be taken for granted among individuals from the area with a high treatment rate. From the present observations, a 'correct' level of treatment provision could not be identified. (+info)
