A wide variety of health care options--home-based, indigenous, and cosmopolitan--exists in northern Balochistan, Pakistan. This paper examines health-seeking behavior in the area of mother and child health for villagers in this pluralistic medical setting. The analysis of a specific series of illness episodes shows that the majority of cases obtain treatment from different medical systems for a single episode. Interest in medications takes precedence over practitioners, and the meaning the villagers attach to such substances is explored. Long-established patterns of behavior relating to indigenous medicine continue to occur when cosmopolitan medicine is utilized. Information presented here helps to explain problems in utilization of cosmopolitan pharmaceuticals and delineates areas for future health programme activity. 相似文献

This study, which was carried out as part of the TURVA project on psychosocial adaptation in old age, is concerned with the significance of social support to people approaching retirement age. The population consisted of 200 urban dwellers and 189 rural dwellers, who were studied at the age of 62. The subjects were either about to retire in the near future or had already retired, and it was assumed that this event causes a certain amount of stress, which may lead to mental disturbance regardless of the amount of social support available to the individual. Intimate relationship and close friendship served as the measures of social support. Mental disturbances were assessed on the basis of the General Health Questionnaire (36-item version) and the number of psychic and especially depressive symptoms. The prevalence of mental disturbance and depressive symptoms was lowest in those people who lived in a close marital relationship and who also described their spouse as empathic. Psychic symptoms were most common in those people who said their relationship to their spouse was distant and who described them as unempathic. The subjects who were not married fell in-between these 2 groups regardless of whether they had an intimate relationship with someone of the opposite sex. A positive marital relationship seemed to provide a shield against depression, while a negative marital relationship tended to make the individual more vulnerable to depression. The role of a close non-marital friendship depended on the respondent's sex. In women, it was associated with a high prevalence of depressive symptoms.(ABSTRACT TRUNCATED AT 250 WORDS) 相似文献

Well-being is frequently said to be the ultimategoal of health promotion. However, health promotion author itiesdo no: offer a clear definition of well-being.Instead health promoters either assume a causal relationshipbetween their activities and the increase of well-beingor claim privileged knowledge of well-being andits means of production, or both. These health promotion strategiesare questioned, and it is suggested that the use of well-beingin health promotion acts to obscure the analysis of health promotionphilosophy and practice. It is concluded that either the termwell-being should be given clear and substantialcontent, or it should be discarded by health promoters. Thelatter option is favoured. 相似文献

Although multiple system atrophy (MSA) is a neurodegenerative disorder leading to progressive disability and decreased life expectancy, little is known about patients' own evaluation of their illness and factors associated with poor health‐related quality of life (Hr‐QoL). We, therefore, assessed Hr‐QoL and its determinants in MSA. The following scales were applied to 115 patients in the European MSA‐Study Group (EMSA‐SG) Natural History Study: Medical Outcome Study Short Form (SF‐36), EQ‐5D, Beck Depression Inventory (BDI), Mini‐Mental state examination (MMSE), Unified MSA Rating Scale (UMSARS), Hoehn & Yahr (H&Y) Parkinson's disease staging scale, Composite Autonomic Symptom Scale (COMPASS), and Parkinson's Disease Sleep Scale (PDSS). Forty‐six percent of patients had moderate to severe depression (BDI ≥ 17); Hr‐QoL scores on the SF‐36 and EQ‐5D were significantly impaired. Pain, the only domain with similar scores in MSA and published PD patients, was reported more frequently in patients with MSA‐P (predominantly parkinsonian motor subtype) than MSA‐C (predominantly cerebellar motor subtype; 76% vs. 50%; P = 0.005). Hr‐QoL scores correlated most strongly with UMSARS motor, COMPASS, and BDI scores but not with MMSE scores, age at onset, or disease duration. The COMPASS and UMSARS activities of daily living scores were moderate‐to‐strong predictors for the SF‐36 physical summary score and the BDI and UMSARS motor scores for the SF‐36 mental summary score. This report is the first study to show that Hr‐QoL is significantly impaired in MSA. Although not all possible factors related to impaired Hr‐QoL in MSA could be assessed, autonomic dysfunction, motor impairment, and depression were most closely associated with poor Hr‐QoL, and therapeutic management, therefore, should concentrate upon these aspects of the disease. © 2006 Movement Disorder Society 相似文献

Since lung transplant recipients are susceptible to infections and inhaled pollution, many centers warn against pets. However, data supporting this recommendation are lacking. Our program is less restrictive regarding pets. This study, for the first time, investigates the association of pets with physiological and psychological parameters in these patients. A questionnaire concerning pets was sent to 104 lung transplant recipients. Lung function tests, levels of exhaled nitric oxide (FE(NO)), need for antibiotic treatments and hospitalizations, creatinine clearance, body mass index (BMI) and demographic data were assessed. Additionally, the questionnaire of life satisfaction (FLZ), a question on summarized life satisfaction (LS), the life orientation test (LOT), the hospital anxiety depression scale (HADS) and the social support questionnaire (F-SozU) were assessed. Response rate was 86%. Fifty-two percent defined themselves as pet owners, whereas 48% did not. The two groups did not differ in demographic or physiological data. Significant differences in FLZ (79/65, p = 0.04), in LS (4.3/3.9, p = 0.01), LOT (32/29, p = 0.006) and F-SozU (4.5/4.2, p = 0.04) were found in favor of pet owners. In lung transplant recipients keeping pets the frequency of somatic complications is not higher compared to lung transplant recipients without pets. After lung transplantation, pets are associated with a better quality of life. 相似文献

The aim of this study was to determine if the effect of psychosocial work environment on psychological well‐being was different for doctors and nurses who work in emergency departments in Spain. A cross‐sectional survey was carried out among 945 emergency doctors and nurses staff from Spain. The outcome variable was the psychological well‐being measured by two dimensions of SF‐36 Health Survey (SF‐36) (mental health, vitality) and one dimension of Maslach's Burnout Inventory (emotional exhaustion). The explanatory variable was the psychosocial work environment evaluated according to Karasek and Johnson's demand‐control model that includes the dimensions of psychological demands, job control, supervisor social support and co‐workers' social support. The adjusted odds ratios and their 95 per cent confidence intervals were calculated by logistic regression. The prevalence of low vitality, bad mental health and high emotional exhaustion was higher among doctors than nurses. Exposure to high psychological demands increased the probability of low vitality, bad mental health and high emotional exhaustion among doctors and nurses. Low job control and low co‐workers' social support at work were associated with poor psychological well‐being only among doctors. Low job supervisors' social support increased the risk of bad mental health among doctors and of high emotional exhaustion among nurses. There is a different effect of psychosocial work environment on psychological well‐being between doctors and nurses. Copyright © 2007 John Wiley & Sons, Ltd. 相似文献

Registration of all hospitalized stroke patients is practiced in Sweden in order to assess care quality. Data in this register, Riks-Stroke (RS), may be biased due to incomplete registration. The purpose of this paper was to report changes in stroke outcome in relation to fluctuations in registration. Patients registered in RS at a hospital during the period 1994–2005 were analyzed. Case fatality at 28 days, living conditions, and activities of daily living (ADL) performance at 3 months were correlated to the number of patients registered and follow-up frequency. A total of 4994 stroke cases were registered during the period. A high annual registration rate was significantly correlated to a high case fatality ratio. A low annual follow-up rate was associated with a low proportion of patients living in their own home without any need of help. Quality parameters are sensible for selection bias, which make them difficult to compare over time and between hospitals. We suggest that by weighing outcome data against stroke severity, safer conclusions may be drawn. Additionally, hospitals considering setting up quality registers should make every effort to attain complete case ascertainment at all times, including patients managed outside the hospital, in order to avoid selection bias. 相似文献
