Purpose: This study examined whether rural women, who had a high prevalence of prehypertension and hypertension upon enrollment in a wellness program, would also have a high prevalence of other cardiovascular disease risk factors such as low fitness and/or dyslipidemia. Methods: Data were analyzed from 225 rural women, ages 50-69, enrolled in a healthy eating and activity clinical trial. Cardiovascular health histories, fitness measures, blood pressure, and fasting blood serum samples were collected following standardized protocols at rural research offices. Chi-square and MANOVA were performed to examine differences in health characteristics, lipids, and fitness across blood pressure categories. Results: Fitness indicators of estimated VO2max, 1-mile walk time, and resting heart rate differed between the blood pressure groups, with those in the prehypertensive and hypertensive groups having less desirable profiles than those in the normotensive group. Triglyceride levels of 150 mg/dL or greater, were observed in 36%, 32%, and 16.7% of women who had hypertensive, prehypertensive, and normal blood pressures, respectively. Conclusions: The need for routine blood pressure screenings by practitioners is reinforced by finding that rural women screened via PAR-Q and/or physician clearance had a high prevalence of prehypertensive and hypertensive blood pressures, in addition to low fitness and nonoptimal triglycerides. Practitioners need to provide counselling based on results and refer to other providers as appropriate.Key Words: blood pressure, lipids, fitness, rural women  相似文献

Institutions of higher education acknowledge that online learning represents a growing segment of the modern learning environment, and most students have mastered basic computer skills. However, reluctance to engage in online learning remains among both faculty and students. This article presents a case study of three schools of nursing that collaboratively developed and implemented an online undergraduate-nursing course. The article discusses the challenges that were encountered by faculty and students. The faculty used the distance education literature to address these challenges related to technological, institutional, and pedagogical aspects of online learning, as well as the recruitment and retention of online learners. Quantitative and qualitative methods were used to evaluate the effectiveness of the course. The paper concludes with suggestions to overcome the challenges of online learning, such that faculty and students receive the inherent rewards.  相似文献

BACKGROUND: Information technology (IT) has slowly been implemented in many health-care organizations (i.e. hospitals). The use of computers has advanced to home care and long-term facilities. Consequently, it is important that nurses are able to demonstrate competence and feel confident in the use of IT. Yet, research has reported that nursing students have varying degrees of competence and experience with IT. AIMS: The purpose of this study was to ascertain nursing students' and nursing educators' self-reported attitudes, skills and experiences using IT. METHODS: Data were collected through a written survey distributed and completed by 247 nursing students (45 of whom were registered nurses who participated in extension courses) and 52 staff members from the nursing faculty at a university in Sweden. RESULTS: Two-thirds of the students and 92% of the nursing educators had access to the Internet from their homes. Of the students, 71% identified their IT skills as being sufficient for their current or future work as a registered nurse. Nurse educators were less confident in the students' ability, reporting that only 29% of nursing students had sufficient IT skills. Comparatively, 48% of the nursing educators believed that they themselves had sufficient IT skills for their role as a nurse educator. CONCLUSIONS: It is important that nursing students have basic IT skills and are familiar with e-mail, word-processing and various databases on the World Wide Web. Findings indicate that participants had a deficit in these skills, suggesting the need to integrate IT into the nursing curriculum.  相似文献

Policies to expand higher education (HE) in the UK have emphasised the importance of widening participation by under-represented groups. However, the attention has shifted from who participates in HE (and who does not) to the different institutions attended by students from different backgrounds. Researchers have typically investigated this issue by comparing rates of entry to different types of university. This paper proposes an alternative approach; it uses concepts of social segregation, hitherto applied mainly to secondary schools, to analyse UCAS data on the social and demographic characteristics of entrants to HE. It estimates indices of segregation between HE institutions, and between subject areas within institutions, for selected cohorts of entrants to full-time undergraduate courses between 1996 and 2010. Levels of segregation during this period have been relatively high in relation to ethnicity and independent schooling, lower in relation to age and lowest in relation to gender, disability and social class. Most indices show stability over time, with a decline in the segregation of non-white ethnic groups and a small increase in segregation of independent school students. Levels of segregation differ across the four UK home countries, and tend to be highest in England.  相似文献

The central purposes of this study were to review the development and evolution of the Scientific Attitude Inventory (SAI) and then reevaluate the psychometric properties of the revised form of the SAI, the Scientific Attitude Inventory II (SAI‐II). The SAI‐II was administered to a convenience sample of 543 middle and high school students from five teachers in four schools in four school districts in San Antonio, Texas, at the beginning of the 2004–2005 school year. Confirmatory factor analysis on the full data set failed to support the existence of a 12‐factor structure (as proposed by the scale developers) or a one‐factor structure. The data were then randomly divided into exploratory [exploratory factor analysis (EFA)] validation and confirmatory [confirmatory factor analysis (CFA)] cross‐validation sets. Exploratory and confirmatory models yielded a three‐factor solution that did not fit the data well [χ2 (321) = 646, p < .001; RMSEA = .061 (.90 CI = .054–.068); and CFI = .81]. The three factors were labeled “Science is About Understanding and Explaining” (13 items), “Science is Rigid” (6 items), and “I Want to Be a Scientist” (8 items). The α‐coefficients for these three factors ranged from 0.59 to 0.85. Whether these identified subscales are valid will require independent investigation. In this sample, and consistent with prior publications, the SAI‐II in its current form did not have satisfactory psychometric properties and cannot be recommended for further use. © 2008 Wiley Periodicals, Inc.
