This study investigated physical activity and fitness of midlife and older rural women. Random-digit dialing was used to recruit 225 women (57.9 +/- 5.6 years old). Self-reported activity (moderate activity, flexibility, and strength) and fitness (body composition, flexibility, strength, and estimated VO(2max)) were assessed. The women demonstrated low daily energy expenditure (30.74 +/- 10.63 kcal x kg(-1) x day(-1)) and estimated VO(2max) (20.12 +/- 7.81 ml x kg(-1) x min(-1)), with 51.5% reporting fair or poor health. Few women reported meeting Healthy People 2010 targets for moderate activity (43.1%), flexibility (28.9%), or strength )14.2%). When classified by estimated VO(2max) into three categories, differences were observed for body-mass index, percent body fat, sit and reach, and timed chair stands, with the poorest performance by those with low cardiorespiratory fitness. Adherence to Healthy People 2010 targets for moderate activity and strengthening was associated with higher cardiorespiratory fitness. These rural women are targets for physical activity interventions because of their sedentary behaviors and low cardiorespiratory fitness.  相似文献

If we wish to incorporate parents and community members as full partners in building character among youth, then the activities and programs in which youth participate during their out-of-school time are potentially important venues. This chapter describes how numerous agencies in a single community partnered with a university, with the help of the cooperative extension agent, to collect local data on how adolescents used out-of-school time, what they thought about right and wrong, and how well their own behavior comported with their understandings of what was right. Results indicated that surveyed youth characterized themselves as thinking more than acting in ethical ways. For instance, nearly half acknowledged having cheated on a test at least once in the past six months, although the vast majority thought that cheating was wrong. The three pathways the community identified for reaching youth were (1) extracurricular activities at school such as sports, yearbook, and pep club; (2) organized nonschool pursuits such as music, dance, hiking, and biking; and (3) religious activities. They found that nearly 90 percent of high school-aged respondents participated in one or another of these venues.  相似文献

Two types of reporting inconsistency for sexual initiation were analyzed--event occurrence and its timing--using data from two waves of the National Longitudinal Study of Adolescent Health (Add Health). Overall, 11.1% of those who reported they were sexually active at the time of first interview denied this at the subsequent one. Males of each race/ethnic group had higher percentages of inconsistency than their female counterparts. Being older, not living with parents, or having a highly educated mother was negatively associated with rescinding. Among those reporting sexual experience at both interviews, only 22.2% reported the same date of first sex. On average, teens revised their age at first sex to older ages, and boys, especially African American boys, had large variability in reporting dates, as did teens with lower verbal ability. Seven strategies for resolving inconsistent reports are presented and implications for substantive findings are discussed.  相似文献

In this article we will show how a relational approach provides a conceptual framework that shapes and informs culturally sensitive practice with a severely disturbed client. We argue that a relational approach facilitates therapeutic action through the intense focus on countertransference, the close attention to enactments, and the therapist's authenticity and self-disclosure. Additionally, we emphasize that a therapeutic matrix that includes the cultural, racial, socioeconomic, and institutional factors, increases the likelihood clinicians will attend to what Perez-Foster calls their dissociated and disavowed personal values. We present a case that had a less than satisfactory outcome where the therapist found herself in a sea of trouble. The case illustrates how a relational approach enhanced the therapist's understanding of the case and allowed her to continue to work with a difficult and challenging client. We conclude by suggesting that our conceptual understanding of this case exemplifies a necessary and appropriate focus for future social work research and practice.  相似文献

The conception of nonprofit organizations as institutional bridges that mediate within an environment of interrelationships is a useful device for informing strategic thinking by nonprofit professionals and volunteers. The bridge metaphor neatly explains not only the rise in number of nonprofit community organizations, but also the process by which leaders of the private and public sectors have formed partnerships to project the wealth and assets of communities.  相似文献

In this study, the link between marital happiness and the advent of children is demonstrated, accounting for dual earner status, sex role traditionalism, and marital structure. A subset of 1,275 respondents from a longitudinal data set (Marital Instability Over the Life Course: A Three Wave Panel Study, 1980–1988) whom remained married through the 3 waves was used to compare the level of marital happiness of respondents who added children between waves to those who did not. Although the addition of children negatively affected marital structure and thus indirectly lowered marital happiness, results showed children also had positive counterbalancing direct effects. Dual-earner status, income, and sex role nontraditionalism were shown to mitigate the negative effects of children on marital happiness.  相似文献

This article examines the changes in adoption practices over the past decade by referencing a series of 1985 articles published by Child and Adolescent Social Work Journal that presented theoretical considerations for maintaining closed adoptions. The author uses her own experience as an adoption professional, those articles currently published in the field of adoption and the experience of those most impacted by adoption, birthparents, adoptive parents and adoptees, in examining and presenting the benefits and value of open adoption.  相似文献

This study examined the feasibility of using a Web-based survey to collect alcohol and other drug use data from secondary school students in an urban school district in the Midwest. A Web-based survey was self-administered by a random sample of 6th through 11th grade students in the spring of 2002. The final sample consisted of 1,536 secondary school students (781 women and 755 men). The sample was 57% White, 40% African American, and 3% from other racial and ethnic groups. Several indicators of data quality were examined including response rate, absenteeism, refusals, substantive data, and data processing time. The study achieved a response rate of 89.1%. The results of the present study provide evidence that a Web-based survey can be successfully implemented in an economically and racially diverse urban sample of secondary students. While researchers conducting survey research within secondary schools should consider using Web-based survey approaches, additional research is needed to compare Web-based surveys to more traditional approaches to collecting data.  相似文献
