汕头卫生检疫局空港处对汕头航空口岸—宗入境二级货包的监测过程及对有关运输工作人员作了放射知识问卷调查。从中发现。运输单位货物存放设施落后。有关工作人员放射卫生知识欠缺,对放射污染可能造成的危害缺乏正确的认识。为此,笔者提出了自己的看法,以期对放射监测工作的进一步完善提供参考。  相似文献

本文报道了一起183例农民阴囊皮炎的爆发流行,发病率高达56.63%,不同的年龄、职业与发病率无显著差别,八月份为发病高峰。同时患有口角炎、舌炎并发症者占45.65%,取14例典型患者的阴囊鳞屑作真菌镜检,检出霉菌1例。85例患者经采用核黄素10mg,加复合维生素B10mg,每日两次连服七天进行试治,治愈率为96.47%(82/85),将19例患者与20例健康者对照,作4h尿中核黄素负荷试验比较,结果两者在统计学上具有显著性差别(u=2.11,P≤0.05)。经膳食营养调查,发现6~10月份核黄素供给不足47%。由此证明,发病与核黄素缺乏有关。  相似文献

The utilisation of antidiabetic drugs reflects both the prevalence of diabetes and the different therapeutic traditions of physicians. A questionnaire survey to study attitudes to the use of oral antidiabetic drugs amongst physicians and possible changes in treatment habits was carried out in a representative sample of Finnish physicians (n=454) in 1992 and the results were compared with those of a similar survey carried out in 1985, and with drug utilisation statistics.The mean fasting blood glucose level at which a physician would start pharmacological treatment was 8.7 mmol·l–1, which was significantly lower than in the 1985 survey. The responses to various case histories suggested a more active approach to pharmacological treatment compared to the 1985 survey. Insulin treatment especially seems to have gained in popularity. This change in attitude was paralled by an increase in the consumption of antidiabetic drugs in Finland during the observation period. The increase in use of oral drugs was steeper in Finland than in Norway and Sweden.Whether this active approach will improve the metabolic control and prognosis of patients with Type 2 diabetes, remains to be demonstrated.  相似文献

A food frequency of consumption questionnaire was completed by 137 diabetic outpatients attending the University of Wales Hospital in Cardiff, to provide information about the use of special dietary products.
Seventy-four per cent of the diabetics used special dietary products, the most popular of which were artificial sweeteners (45%) and preserves (47%), followed by squash (34%), sweets (31%) and chocolate (31%). Twenty per cent of diabetics consumed biscuits and tinned fruit. Cake and other products (e.g. jelly), were used by less than 10% of the respondents. Over half of all the diabetics consumed one or more products on a daily basis. The use of special products bore no significant relationship to the sex of the respondents, nor to the duration of the diabetes. However, a significantly higher proportion of the Insulin Dependent Diabetics (IDDM) group used dietary products compared with the Non-Insulin Dependent Diabetics (NIDDM) group. This can be explained largely by the differences in age between the diabetics; the under-18-year-old age group (who were all IDDM respondents) were the greatest users of sweets, chocolate and squash.
Forty-three per cent of diabetics who did not use special food products cited at least one reason for non-use. The reasons included dietetic advice (NIDDM respondents only), high cost, poor palatability, lack of availability and unsuitability for other members of the family.  相似文献

Objective. To quantify the relationship between utilization of care among the uninsured and the structure of the local health care market and safety net.
Data Sources/Study Setting. Nationally representative data from the 1996 to 2000 waves of the Medical Expenditure Panel Survey (MEPS) linked to data from multiple secondary sources.
Study Design. We separately analyze outpatient care utilization and whether an individual incurred any medical expenditure among uninsured adults living in urban and rural areas. Safety net measures include distances between each individual and the nearest safety net providers as well as a measure of capacity based on local government and hospital health expenditures. Other covariates include the managed care presence in the local health care market, the percentage of individuals who are uninsured in the area, and local primary care physician supply. We simulate utilization using standardized predictions.
Principal Findings. Distances between the rural uninsured and safety net providers are significantly associated with utilization. In urban areas, we find that the percentage of individuals in the area who are uninsured, the pervasiveness and competitiveness of managed care, the primary care physician supply, and safety net capacity have a significant relationship with health care utilization.
Conclusions. Facilitating transport to safety net providers and increasing the number of such providers are likely to increase utilization of care among the rural uninsured. Our findings for urban areas suggest that the uninsured living in areas where managed care presence is substantial, and especially where managed care competition is limited, could be a target for policies to improve the ability of the uninsured to obtain care. Policies oriented toward enhancing funding for the safety net and increasing the capacity of safety net providers are likely to be important to ensuring the urban uninsured are able to obtain health care.  相似文献

目的:掌握中国维和部队士兵性观念和性心理状况,力图加以正确引导和心理干预。方法:在维和任务中期,采用自编问卷,对314名中国驻利比里亚维和士兵进行性观念和性心理方面的调查。结果:超过90%的士兵性知识来源于自学,部分士兵性知识相对缺乏,通过集训的学习,仍有77%的战士对“艾滋病”有恐惧感。与未婚士兵相比,已婚士兵显示出更成熟的性心理(P<0.05);而性观念上差异没有显著性(P>0.05)。结论:针对不同群体进行有效的心理干预和心理疏导,能让士兵理智地对待自己的性欲和愿望,把性能量升华为内在的工作动力,创造性地开展维和工作。  相似文献

Fifty-five students and staff at Robert Gordon's Institute of Technology completed a food frequency questionnaire and then weighed their food for one week. Several methods of calculating nutrient intakes from the questionnaire are compared to results from the weighed inventory. Intakes of energy and several nutrients calculated using estimated typical portion weights were less than those derived from the weighed inventory. Food groups contributing to the apparent under-estimation have been identified. A further method of calculation involved derivation of a factor for each food group such that the frequency estimated from the questionnaire multiplied by the factor equalled the average weight of the foods in that group that had been eaten. Using these factors instead of the typical portion weights resulted in closer agreement to the weighed inventory method, but the difference ranged from positive for some groups to negative for others. Use of separate factors for each group of subjects reduced the range of differences to the weighed inventory method.  相似文献
