Risk factors of type 2 diabetes among Korean adults: The 2001 Korean national health and nutrition examination survey

This study aimed to identify risk factors for type 2 diabetes (T2D) in Korea, a rapidly changing country. Data of 5,132 adults aged 20-85 were used from the 2001 Korean Health and Nutrition Examination Survey. Multiple logistic regression was carried out to identify risk factors for T2D. Three models were specified: (i) socioeconomic and demographic factors (model 1: age, gender, education, poverty income ratio, employment), (ii) behavioral risk factors and covariates (model 2: obesity, physical activity, smoking, alcohol drinking, dietary quality, family history of T2D, co-morbidity) and (iii) socioeconomic, demographic, and behavioral factors (model 3). The prevalence of T2D was 7.4%. Less education (OR 1.41, 95% CI 1.08-1.84), age (OR 2.19, 95% CI 1.56-3.08 in 40-59 yrs, OR 4.05, 95% CI 2.76-5.95 in 60 yrs + comparing to 20-39 yrs) and abdominal obesity (OR 2.24, 95% CI 1.79-2.82) were risk factors for T2D even after controlling for other factors simultaneously. There was a significant association of T2D with ever smoking (OR 1.34, 95% CI 1.06-1.67). The relationship of age with T2D was modified by gender in model 1 and the relationship of smoking with T2D was modified by obesity in model 2. Less educated, older, obese or ever smokers were more likely to have T2D. Gender mediated the relationship of age, and obesity mediated the relationship of smoking, with T2D. Intervention programs for T2D in Korea should take the interactions among risk factors into account.     

The Colorado Haemophilia Paediatric Joint Physical Examination Scale: normal values and interrater reliability

Persons with haemophilia often experience their first joint haemorrhage in early childhood. Recurrent bleeding into a joint may lead to significant morbidity, specifically haemophilic arthropathy. Early identification of the onset and progression of joint damage is critical to preserving joint structure and function. Physical examination is the most feasible approach to monitor joint health. Our group developed the Colorado Haemophilia Paediatric Joint Physical Examination Scale to identify earlier signs of joint degeneration and incorporate developmentally appropriate tasks for assessing joint function in young children. This study's objectives were to establish normal ranges for this scale and assess interrater reliability. The ankles, knees and elbows of 72 healthy boys aged 1 through 7 years were evaluated by a physical therapist to establish normal ranges. Exactly 10 boys in each age category from 2 to 7 years were evaluated by a second physical therapist to determine interrater reliability. The original scale was modified to account for the finding that mild angulation in the weight-bearing joints is developmentally normal. The interrater reliability of the scale ranged from fair to good, underscoring the need for physical therapists to have specific training in the orthopaedic assessment of very young children and the measurement error inherent in the goniometer. Modifications to axial alignment scoring will allow the scale to distinguish healthy joints from those suffering frequent haemarthroses.     

Evaluating anxiety in patients attending optometric practice

Although anxiety is a well-established obstacle to the delivery of effective health care, there have been no attempts to measure it in the optometric consulting room. In this paper, we introduce physiological and psychological techniques that may be used to evaluate anxiety and arousal in the consulting room and present data from a small group of patients attending for a routine eye examination. Specifically, arousal was assessed before, during, and after the examination by measuring skin conductance in five patients. Anxiety was evaluated using the State-Trait Anxiety Inventory. Our data confirm the ability of these techniques to quantify arousal and anxiety in the optometric consulting room and reveal a previously unknown but important facet of the eye examination. We conclude that these techniques are suitable for use in further experimental work and may be used to identify factors capable of reducing anxiety in the optometric consulting room.     

佛山市城区集体儿童健康状况调查分析

目的了解佛山市城区集体儿童健康状况,以制定干预措施。方法采用随机整群抽样的方法,抽取本市城区共15间幼儿园,并对各间园所的儿童体检的资料数据进行整理和分析。结果佛山市集体儿童缺点总检出率为71.40%。其中私营幼儿园儿童缺点患病率明显高于事业单位的幼儿园(P<0.05),有显著性差异。儿童骨矿物质测定缺钙的检出率为13.73%。男女儿童无性别差异。结论今后继续加强对幼儿园的管理工作,私营的幼儿园管理工作是我们今后管理工作的重点,做好防治工作,降低患病率,增强儿童的身心健康。     

高血压病血管内皮功能障碍及治疗

内皮细胞功能障碍是近年来的热门研究课题,从基础到临床受到广泛重视。高血压是发病率最高的心血管疾病,其发病环节与内皮细胞功能关系密切,二者均是心脑血管事件链中的重要环节。本文回顾了多种内皮因子的功能及其与高血压的关系,高血压病内皮功能障碍的可能机制,肱动脉超声检查方法以及内皮功能障碍的治疗对策。

目的 探讨影像学检查(image examination，IE)对闭合性腹部损伤(closed abdominal injuries，CAI)的诊断价值。方法 1997—2003年间对142例血流动力学稳定的闭合性腹部损伤病人行影像学检查，结合术中所见，分析比较IE的准确性和差异。结果 IE阳性112例病人中，104例经剖腹探查术证实有腹腔脏器损伤，8例假阳性；30例IE阴性病人，真阴性19例，假阴性11例；敏感性为90．4％，特异性为70．4％，准确性为86．7％。结论 IE具有早期诊断价值，IE阳性对判断腹腔内实质性脏器损伤的特异性最高，IE阴性，需行进一步检查排除其他隐匿性损伤；结合临床表现及其他辅助检查综合分析，准确性会更高。
