Urinary iodine levels in children (5–11 years) and in adult males and females (15–44 years) of three ecological zones (hilly, flood-prone and plains) of Bangladesh were analyzed to determine the status of biochemical iodine deficiency in the country. Data indicated that a large majority of the population all over Bangladesh have biochemical iodine deficiency urinary iodine excretion (UIE) less than the accepted cut-off level of 10 μg/dl. Adults were deficient to comparable degrees, 31.3% severely iodine deficient. The flood-prone zone was less affected: 71.7% children had iodine deficiency and 25% were severely deficient. Adults of this zone were less affected than the children. Iodine deficiency was least severe in the plain zone: 59.8% children were biochemically iodine deficient and of them 23.4% had UIE less than 2.0 μg/dl. In the case of the adults of this zone, 60.8% were biochemically iodine deficient and 20.6% had severe iodine deficiency. The results indicate that Bangladesh as a whole is an iodine deficient region, with the hilly zone being the most severely affected. Children were slightly more affected than the adults, and females were more affected than the males. 相似文献

目的对新疆和田地区碘缓释器的使用进行系统评估;方法采用现场调查和实验室检测相结合的方法进行。结果土盐水使用碘缓释器组的水碘含量为23.1±49.0(mg/kg),明显高于土盐水未使用碘缓释器组的0.06±0.05(mg/kg);土盐水使用加碘器组尿碘中位数育龄妇女为125.3μg/L,儿童为134.5μg/L,均低于碘盐组但明显高于土盐水未使用碘缓释器组。有33.9%的育龄妇女和31.7%的儿童尿碘水平在100μg/L以下,25.4%的育龄妇女和29.3%的学龄儿童尿碘水平在300μg/L以上;土盐水使用加碘器组目标人群的甲状腺肿大率育龄妇女和学龄儿童分别为19.1和19.0%,,明显低于土盐水未使用碘缓释器组并接近碘盐组水平;土盐水使用加碘器组IDD知识知晓率在育龄妇女和儿童分别为72.9%和72.7%明显高于土盐水未使用碘缓释器组并接近碘盐组的水平。结论在和田地区使用碘缓释器作为预防和控制碘缺乏病的临时性替代措施是有效的。 相似文献

中国通过普及食盐加碘（Universal SaltIodization,USI）消除碘缺乏病,并持续巩固了防治成果。随着碘缺乏病防治工作的顺利开展,高水碘问题也引起了关注。为了了解和掌握我国水源性高碘问题及干预状况,开展了相关调查。通过查阅有关文献资料和访谈,了解高水碘地区的分布状况、监测工作进展情况、采取的干预措施等;通过深入高碘县的高碘村,了解停供碘盐和改水措施的落实、群众的认知等情况;并请县级盐业部门人员参加,探讨供应不加碘食盐的措施和对策。本报告的主要内容包括：高水碘地区的分布状况,监测工作进展情况,采取的干预措施及其落实情况,存在问题和建议等。 相似文献

目前,无线网络拥塞是当今计算机网络中存在的普遍现象,如何改进无线网络中TCP的拥塞性能成为现在研究的热点．利用新的端到端检测作为无线TCP改进方案,当端到端时延较大的时候,在传输层对丢失的数据做出响应之前,会导致更加冗长的往返时间估计,使得通信性能明显下降．在实验中发现IDD值的增长是网络发生拥塞的充要条件．XCP协议通过显式地通告发送端应该增加或降低多大的发送窗口来使各用户流公平共享网络资源,XCP—B来源于XCP,是无线网络中一个很成功的应用． 相似文献

Members of a knowledge translation and exchange (KTE) research team assessed the training needs of the teaching staff at a school for individuals with intellectual/developmental disabilities (IDD). In response to this need, KTE researchers retrieved peer‐reviewed articles for training staff working with individuals with IDD who exhibit challenging behaviours. These articles were categorised according to the following training content: (1) interventions designed to reduce the frequency of challenging behaviours; (2) appropriate ways to manage challenging behaviours in the moment to promote safety for all parties and/or to terminate the ongoing behaviour; and/or (3) procedures or perspectives relevant to coping with or ameliorating the negative impacts of challenging behaviours on staff. We then examined the training methods (teaching strategies, training duration) involved in teaching the content and assessed the effectiveness of these programmes. Overall, we found that effective training programmes consisted of workshops, practica and feedback on specific skill performance. Some forms of brief training were effective for increasing staffs' knowledge/skills and reducing the frequency of challenging behaviour. 相似文献

Low employment rates of individuals with intellectual disabilities in Australia stem from apprehensions about their abilities to engage in work, and employers’ low confidence in hiring them in paid positions. Drawing on principles of evaluative reasoning, this paper reports on findings from a mixed-methods formative evaluation. It was conducted to understand the need for a two-year Education-to-Work training program, the quality of its content, and the views that 8 parents, 5 facilitators, and 4 students had about changes attributable to the program after its first year. Program performance was assessed against the quality standards of excellent, good, satisfactory, marginal, and needs improvement. Findings from the evaluation highlighted the potential usefulness of post-secondary education (PSE) transitioning programs to secure longer term employment, for adults with Down syndrome. Specific recommendations are made to improve the quality of the program, and abstractions gleaned from the study are highlighted. 相似文献
