1977～1990年同济医科大学新生视力状况分析

用统计学方法对14年来（1977～1990年）我校6746名新生（13492只眼）的视力状况进行分析。结果表明；新生正常视力逐年减少，视力不良率相应上升（P＜0.001）。城市学生的视力比农村学生差，男生的视力优于女生（P＜0.001）。17～19岁组的视力明显低于其他年龄组（P＜0.001）。高考分数线升高与正常视力者减少呈明显负相关；而与视力不良者增加呈正相关（P＜0.001,＜0.05）。本文认为近距离用眼持续时间过长及环境视域小等是引起视力不良的主要原因。     

A comparison of nutritional intake, functional status and muscle strength between elderly day hospital and day centre attenders in South London

Two sample groups of elderly were compared from a population living in South London. One group attended a local day centre (a socially orientated establishment), and the other attended a local day hospital (a therapeutically orientated establishment).
The aim of the study was to compare nutritional intake, functional status and muscle strength between these two groups.
The mean nutritional intakes of the day hospital and day centre attenders were similar. Intake of macronutrients, with the exception of fibre, met Recommended Daily Allowances (RDAs) in both groups. In take of folic acid, vitamin D and zinc fell below recommendations in both groups.
Low intake of folic acid was improved by supplementation, and some individual blood levels of folate reflected this. Blood folate levels were generally within normal limits. Low intake of vitamin D was improved by supplementation, but blood levels were generally normal anyway. There was, however, a tendency for the more dependent day hospital patients to have lower vitamin D levels. This group also had less sunshine exposure.
Communal dining, whether in the setting of day hospital or day centre, may have been an essential means of bolstering nutritional intake for many 'at risk' elderly.
There were significant differences in functional status and muscle strength in favour of the day centre group and these indicate that anthropometric indices rather than nutritional or biochemical indices were the most reliable markers of disease and disability in this study.
The effect of fortifying local meals-on-wheels was also highlighted, and suggests that this may be one means of preventing nutritional deficiencies in the vulnerable, house-bound elderly.
Alcohol intake was reported as being modest. However, discrepancies were noted on review of biochemical indices known to be influenced by alcohol intake.     

北京、广州、上海城市居民营养知识、态度、行为的调查

对北京、广州和上海三大城市随机抽取的９６５名年龄在２０～５０岁的城市居民进行有关营养知识、态度和行为（Ｋ－Ａ－Ｐ）的调查。结果显示，三地区调查对象的营养知识水平不高。营养知识的得分与其自身受教育程度有相关性（ｒ＝０．３０１１，Ｐ＜０．０１）。年龄在３５岁以上的对象，营养知识的得分高于年轻人；三地区调查对象对营养知识的获取，合理的膳食模式，卫生的饮食习惯均持有积极、肯定的态度。食物消费频度调查结果表明，米／面、肉／禽、蔬菜、水果、奶及奶制品的消费量较高。此外，８９．５％，７８．８％和４７．８％的调查对象分别选择报纸、电视、广播作为其主要营养信息来源。本次调查为将来的营养宣教的内容和方法提供依据。     

三峡地区大学生膳食调查与分析

目的：为开展大学生膳食营养教育提供依据。方法：采用记录和询问相结合的方法对301名大学生进行膳食调查。结果：男生的膳食营养状况比女生好。男生对热能、磷、铁、维生素A和维生素B1的摄入量均超过推荐量（Recommended Nutrient Intake，RNI），蛋白质达到RNI的94％，但钙、维生素B2和维生素C摄入不足，分别达到RNI的54％、71％、69％。女生磷、铁、维生素B1的摄取量超过RNI，维生素A达到RNI的90％，基本满足需要，但蛋白质、能量、钙、维生素B2和维生素C分别达到RNI量的76％、78％、57％和54％。男女生摄入的优质蛋白质均达到总摄入量的41％。男女生均有早上餐能量过低，晚餐量过高的现象。结论：大学生的膳营养水平比以往有所提高，但某些营养素仍严重缺乏，应加强对大学生的膳食营养教育。     

广西武鸣华侨农场心血管病危险因素的调查研究

对广西武鸣华侨农场4158人进行基线普查,410人进行膳食调查和作8小时夜尿电解质测定,并将高血压低发区广西的资料与高发区的北京作对比.结果显示,体重指数高是高血压一个重要的危险因素,而体重过重又与膳食中摄入碳水化合物和总热量大有关.另一主要的危险因素是钠,膳食中摄入钠高,尿Na和Na/K比值高者,血压水平和高血压的患病率亦高.     

门诊抗菌药物使用调查

目的了解医院门诊抗菌药物应用情况，为临床合理应用抗菌药物提供依据。方法抽查2006年1月至11月份门诊处方18163张，统计抗菌药物使用情况，并评价其合理性。结果含抗菌药物处方5809张，占总处方数31．98％。头孢菌素类药物使用率最高，其次为喹诺酮类。给药途径主要为口服给药。结论抗菌药物应用基本合理，但使用中存在一些问题，应引起重视。     

阳城县居民吸烟状况调查分析

对阳城县3646名15岁以上人群吸烟状况分析表明,男性吸烟率63.71％,女性吸烟率0.64％,男女合计吸烟率31.49％,并对不同年龄、职业、文化程度与吸烟率的关系进行了分析。吸烟心理动机:“烟草成瘾”占32.06％,“消遣”占28.48％,“解除疲劳”占16.90％,“交际”占22.56％。吸烟人群的4周患病率和慢性病患病率均高于不吸烟人群,两组差别有显著性(P<0.05,P<0.001)。

The practice of breast self-examination results in the earlier detection and better clinical course of Japanese women with breast cancer

Using a questionnaire survey, we analyzed the relationship between the frequency of breast self-examination (BSE) and the clinical stage and course of breast cancer in Japanese patients. BSE had been performed monthly by only 5.4% of the patients (M group), occasionally by 35.4% (O group), and not at all by 59.2% (N group). There was a positive relationship between more frequent BSE and an earlier clinical stage, the percentages of Tis/stage 0 and I for the M, O, and N groups being 83%, 44%, and 36%, respectively (P<0.05). The mean maximum tumor diameters for the three groups were 1.7cm, 2.5cm, and 3.0cm, respectively. The tumor size in the M and O groups was significantly smaller than that in the N group atP<0.01 andP<0.05, respectively. The percentages of patients in the M, O, and N groups who underwent breast-conserving therapy were 42%, 11%, and 19%, respectively, with patients who had performed monthly, BSE more frequently undergoing breast-conserving therapy (P<0.05). At a median follow-up time of 34 months, 0%, 3.8%, and 7.6% of the patients from the M, O, and N groups, respectively, had died of breast cancer, the overall survival curve of the M group being significantly better than that of the N group (P<0.01). This retrospective study suggests the positive correlation of BSE frequency with earlier detection, and a more favorable clinical course in Japanese breast cancer patients.     

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.
