Summary The aim of this study was to assess the prevalence of psychiatric disturbance in three primary medical care settings (Brasilandia, Servidor and Barra Funda) in a large city of a developing country and the effect of relevant sociodemographic factors (sex, age, marital status, occupation, migration, colour of skin and housing) on minor psychiatric morbidity.The prevalence rates of psychiatric morbidity were estimated at two levels: for minor and for severe psychiatric disturbance. The extent of minor psychiatric morbidity was found to be very high in the three primary medical care clinics (Brasilandia 56%, Servidor 50% and Barra Funda 47%) and about one-quarter of persons attending each clinic presented a severe psychiatric disturbance.Two factors were found to be associated with minor psychiatric morbidity (sex and family income per capita) when the joint effects of the sociodemographic variables were investigated. Women were more likely than men to present a minor psychiatric disturbance and the lower the family income the higher the risk of minor psychiatric morbidity. These findings are discussed in the light of the mental health of the urban poor living in the large cities of developing countries. 相似文献

Metabolic syndrome (MetS) characteristics include chronic inflammation and elevated oxidative stress. This study assessed associations between circulating concentrations of micronutrients/phytochemicals and inflammatory/oxidative stress markers with MetS and MetS components. Adults (N = 606) from the European Health Examination Survey in Luxembourg (2013–2015) were randomly selected. We performed a multivariable logistic regression model using the least absolute shrinkage and selection operator to identify MetS-associated variables. Participants with MetS had higher concentrations of C-reactive protein (CRP), 8-iso-prostaglandin F2α, leptin, insulin, and vitamins E/A, but lower concentrations of adiponectin, beta-carotene, and oxidized low-density lipoprotein. A one-unit increase in log-CRP was associated with 51% greater odds of MetS (OR = 1.51 (95% CI: 1.16, 1.98)). Adults with a one-unit increase in log-leptin were 3.1 times more likely to have MetS (3.10 (2.10, 4.72)). Women with a one-unit increase in vitamin A were associated with 3% increased odds of MetS (1.03 (1.01, 1.05)), while those with a one-unit increase in log-adiponectin were associated with 82% decreased odds (0.18 (0.07, 0.46)). Chronic inflammation best characterized adults with MetS, as CRP, adiponectin, and leptin were selected as the main MetS determinants. Micronutrients did not seem to affect MetS, except for vitamin A in women. 相似文献

There is a lack of robust evidence regarding outcomes for day care use among older people living with long-term conditions (LTCs). Day care is provided by independent, private and voluntary and charitable sectors. This systematic review aims to establish current evidence of outcomes for older people with LTCs attending day care services and outcomes on carers, across all service models. Narrative synthesis of quantitative and qualitative data was undertaken. The review adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A systematic literature search was carried out across eight electronic databases and reference lists of key journals between 2004 and October 2020 were searched. Searches returned 1,202 unique titles. Forty-five articles from 16 countries met the criteria on review of title, abstract and full article. There is limited evidence suggesting improved levels of perceived psychological health, quality of life, perceived general health, physical health and functioning for older people attending day care who have LTCs. The respite function of day care resulted in positive outcomes for carers. Studies evaluating outcomes for participants or carers were limited in quantity and quality. There is limited information regarding outcomes for day care attendance for older people with multiple LTCs from existing literature. Further research focusing on LTCs and day care attendance would benefit this field. 相似文献
