Workplace status and risk of hypertension among hourly and salaried aluminum manufacturing employees
Jane Ellen Clougherty Ellen A. Eisen Martin D. Slade Ichiro Kawachi Mark R. Cullen 《Social science & medicine (1982)》2009
An inverse relationship between workplace status and morbidity is well established; higher job status has been associated with reduced risks of heart disease, hypertension, and injury. Most research on job status, however, has focused on salaried populations, and it remains unclear whether job status operates similarly among hourly workers. Our objectives were to examine whether hourly status itself influences risk of hypertension after adjustment for socioeconomic confounders, and to explore the role of fine-scale job grade on hypertension incidence within hourly and salaried groups. We examined data for 14,999 aluminum manufacturing employees in 11 plants across the U.S., using logistic regression with adjustment for age, sex, race/ethnicity and other individual characteristics. Propensity score restriction was used to identify comparable groups of hourly and salaried employees, reducing confounding by sociodemographic characteristics. Job grade (coded 1 through 30, within hourly and salaried groups) was examined as a more refined measure of job status. Hourly status was associated with an increased risk of hypertension, after propensity restriction and adjustment for confounders. The observed effect of hourly status was stronger among women, although the propensity-restricted cohort was disproportionately male (96%). Among salaried workers, higher job grade was not consistently associated with decreased risk; among hourly employees, however, there was a significant trend, with higher job grades more protective against hypertension. Increasing the stringency of hypertension case criteria also increased the risk of severe or persistent hypertension for hourly employees. 相似文献

This paper describes an innovative approach to preparing high school students with mild disabilities for challenging careers in high tech industries, called High School High Tech (HSHT). Iowa's HSHT Goes to College program has three central elements, each of which is discussed in this paper: High School Preparation—assisting students in identifying a suitable high tech career goal; Higher Education Preparation and Supports—assisting students in selecting college/training programs that match their career goal, and in successfully completing their postsecondary programs; Workforce Entry Assistance—linking students with employers and launching their high tech careers. The paper concludes with a presentation of outcomes to date and recommendations for program enhancements. The information presented here is intended to assist education and rehabilitation professionals interested in establishing similar efforts across the nation. 相似文献

用刀豆蛋白A刺激激素敏感型肾病单个核细胞,并将其培养上清液灌注于大鼠肾内。结合电镜观察,用图像分析仪及体视学方法分别对其肾组织胶体铁染色切片和电镜照片上的足突和滤过裂隙的平均宽度进行测定。结果表明:该病极期上清液灌注的鼠肾小球多阴离子明显减少,足突肿胀、融合,滤过裂隙变窄;而该病缓解组和正常对照组则为阴性。说明该病单个核细胞培养上清液可引起鼠肾小球微小病变型肾病综合征的病变,并揭示该变化可能是由其上清液中一种异常的T淋巴细胞因子所致。 相似文献

选用长白猪8只于麻醉下开胸,于在体猪心上探讨心肌缺血时冠脉仍保留有部分扩张储备,而未被充分利用的机理。实验结果表明:降低左冠状动脉前降支(LAD)内压至4.67kPa时,由LAD分别输入腺苷、山莨菪碱、生理盐水(2ml/min),皆能诱发出明显的LAD流量增加(P<0.05)。在维持LAD内压不变,并持续分别输入上述三种溶液的同时,从LAD远端取血测血液流变学指标,结果显示,输入生理盐水和山莨菪碱使红细胞压积降低,血浆粘度和全血粘度下降;心肌缺血时,冠脉内输注药物所诱发出的“冠脉扩张储备”部分是由于此种给药方式所引起的血液稀释及血液粘度下降的结果。它提示在冠脉狭窄时,血液粘度对狭窄远端的心肌血供可能是一个相当重要的因素,降低血液粘度可能并不亚于扩血管药物的作用。 相似文献

作者用红细胞C_3b受体花环试验和红细胞免疫复合物花环试验对马桑内酯所致癫痫发作大鼠红细胞免疫粘附功能的变化进行了观察,结果表明,癫痫组动物红细胞C_3b受体花环率明显低于对照组,而红细胞免疫复合物花环率相差不显著.提示癫痫发作可导致大鼠红细胞免疫粘附功能降低,因此在癫痫治疗中注意调整和增强患者的红细胞免疫功能具有重要意义。 相似文献

The objective of this study was to test the impact of entacapone (ENT) addition to levodopa with a decarboxylase inhibitor (LD) in full-time-employed patients with Parkinson's disease (PD), focusing on retirement rates, medical absenteeism, self-perception of disability, as well as motor assessments of parkinsonism, motor fluctuations, and dyskinesias. Thirty full-time-employed PD patients (disease onset before age 60 years) and on optimized monotherapy with LD exhibiting minor motor fluctuations or dyskinesias were entered into a 2-year randomized double-blind placebo-controlled study of ENT adjunctive therapy. The outcome measures were the number of full-time-employed patients at study end, cumulative days of medical absenteeism, patient-completed disability assessments, diary records, and the Unified Parkinson's Disease Rating Scale-based measures of motor fluctuations and dyskinesias. LD + ENT treatment was associated with a lower retirement rate (2 [17%] of 12 vs. 6 [50%] of 12; P = 0.12), lower absenteeism rate (21.5 vs. 43.5 days; P < 0.0001), improved self-perception of disability progression over 2 years (change score 1.0 vs. 4.5; P < 0.0001), and lower scores for both motor fluctuations and dyskinesia assessments compared to LD monotherapy. In this pilot study, LD with ENT adjunctive therapy positively influenced employment rate over 2 years; this effect was associated with reduced motor complications and patient perceptions of stabilized disability. 相似文献

This study examined predictors of employment among substance-using men and women enrolled in welfare-to-work programs. Participants were 394 welfare applicants assigned to either coordinated care management or usual care for treatment services and job training and followed up for 1 year to track employment outcomes. Common barriers to work were assessed at baseline in four key domains: disabilities, situational barriers, labor capital, and motivation. Results indicated substantial gender differences in the number and profile of work barriers. Among men, work experience and job motivation were the only significant predictors of employment; among women, multiple factors from each barrier domain predicted job acquisition even when controlling for all other significant predictors. Findings suggest that welfare-to-work programs should emphasize job training and job seeking during the early stages of welfare interventions for men and for many women. 相似文献

用计算机辅助分子片段评价程序分析了59种有机磷化合物诱发沙门氏菌回复突变的资料。发现:有机磷诱发沙门氏菌回变与带甲基的分子片段有关,而带乙基分子片段的有机磷的阳性概率极低;磷酰基上的氧原子似有增强诱变性的作用,硫代磷酰基上的硫原子则似有减弱作用。提示:在这些相关片段中,甲氧磷酰基片段与有机磷诱发沙门氏菌回变相关,可推荐为有机磷诱发阳性的特征描述符;而乙基硫羰磷酰基阳性的概率极低,为阴性结果的描述符。 相似文献
