Introduction: The incidence of stroke has decreased in Sweden as well as in most developed countries, but a high number of migrants have arrived in Sweden, during the last decades, which may have influenced the incidence. Aim: The aim of this study was to examine the incidence of stroke in women, born outside as well as in Sweden. Furthermore, the aim was to examine how socio-economic factors, smoking, and physical activity could modify the risk for stroke. Method: Data from the “Malm&ouml;Diet and Cancer Study” was used for the analysis. In total, 16,857 women were included (14,849 of them born in and 2,008 born outside Sweden), aged 45 - 73 years with a mean age of 57.4 years. Result. A significantly increased relative risk (RR) was found for the incidence of stroke for current smokers in both Swedish-born and migrant women. In Swedish-born women the RR was 1.98 (CI: 1.66 - 2.36) and for migrant women the RR was 1.83(CI: 1.13 - 2.96). The adjusted relative risk for the incidence of stroke in Swedish-born women performing moderate/high physical activity was RR 0.71 (CI: 0.61 - 0.84) and for migrant women it was RR 0.77 (CI: 0.49 - 1.20). The relative risk in relation to low socio-economic circumstances (SES) was significant only for Swedish-born women (RR 0.85 [CI: 0.73 - 0.99]). Among currently smoking Swedish-born women with a low SES the RR was 1.27 (CI: 1.03 - 1.57) in comparison with smoking migrant women, whose RR was 1.68 (CI: 0.92 - 3.09). Conclusion: No differences were found indicating that migrant women in this population had a higher risk as compared to Swedish-born women. However, migrant smoking women were more vulnerable to stroke compared to Swedish-born women. Physical activity was effective in reducing the risk of stroke among the total population and especially in the Swedish-born women. To increase physical activity in middle-aged women, in both migrant and Swedish-born women, is a highly recommended public health strategy. 展开更多

Background: Rheumatoid arthritis (RA) is a chronic and disabling disease that has a major impact on the lives of patients. Objectives: To test the patients’ knowledge about their disease, its treatment, its complications, and if this affects severity of the disease as measured by the disease activity index (DAS 28). Patients and Methods: A sample of 100 patients with RA who met the Criteria of American College of Rheumatology for RA agreed to participate in this study over the period September 2011-March 2012. Patients’ data were obtained by personal interview. The questionnaire included demographic characteristics and the patients’ knowledge about their disease. The disease activity was measured using standard (DAS28). Results: Thirty three percent of the patients didn’t have an idea about their disease, 20% didn’t know the reason for the investigations, 49% didn’t know the treatment and 40% didn’t know the side effects of their medications. Most patients had a high disease activity index, and there was a poor correlation between patients’ educational level and the disease activity. Conclusions: Neither the educational level nor the frequency of hospital admissions had effects on the knowledge about this disease. As most patients had a high disease activity, a better knowledge may improve disease control and prevent complications. 展开更多

Found in the Trans-Himalayas of north-west Yunnan and south-east Tibet, the black-and-white snub-nosed monkey (Rhinopithecus bieti) is one of the world’s most endangered primates. A recent survey indicates that only 15 groups with 2500 individuals remain in the wild. However, the Tibetan Xiaochangdu group may be the only equilibrium group in the field since the last investigation in 1988. To evaluate the effects of traditional culture and socioeconomic activity on biodiversity conservation of R. bieti, we conducted a case study in the Honglaxueshan National Nature Reserve in southeast Tibet from June 2003 to May 2005. Interviews, direct observations, and analysis of socioeconomic data indicated major advantages to the conservation of R. bieti, which included that: 1) traditional culture mainly depended on raising livestock and collecting non-timber products rather than forest planting of Tibetan highland barley; 2) religious beliefs, against to kill any wildlife living on the sacred mountain, were mainly influenced by Tibetan Buddhism; and 3) bigger household numbers were induced by the polyandrous marriage system, which resulted in lower per capita resource consumption than smaller ones. 展开更多
