Physical activity and quality of life in older adults: Influence of health status and self-efficacy 总被引:2,自引:1,他引:1
Edward McAuley Ph.D. James F. Konopack Ed.M. Robert W. Motl Ph.D. Katherine S. Morris B.A. Shawna E. Doerksen M.S. Karl R. Rosengren Ph.D. 《Annals of behavioral medicine》2006,31(1):99-103
Background: Physical activity has been positively linked to quality of life (QOL) in older adults. Measures of health status and global
well-being represent common methods of assessing QOL outcomes, yet little has been done to determine the nature of the relationship
of these outcomes with physical activity.Purpose: We examined the roles played by physical activity, health status, and self-efficacy in global QOL (satisfaction with life)
in a sample of older Black and White women.Method: Participants (N = 249, M age = 68.12 years) completed multiple indicators of physical activity, self-efficacy, health status,
and QOL at baseline of a 24-month prospective trial. Structural equation modeling examined the fit of 3 models of the physical
activity and QOL relationship.Results: Analyses indicated that relationships between physical activity and QOL, self-efficacy and QOL were all indirect. Specifically,
physical activity influenced self-efficacy and QOL through physical and mental health status, which in turn influenced global
QOL.Conclusions: Our findings support a social cognitives model of physical activity’s relationship with QOL. Subsequent tests of hypothesized
relationships across time are recommended.
Funding for this study was provided by the National Institute on Aging (Grant AG 20118). We extend our sincere appreciation

Prematurity Stereotyping by Mothers of Premature Infants 总被引:2,自引:1,他引:1
Previous research has experimentally documented a prematuritystereotype in college students and mothers of full-term infants.The present investigation extends the scope of earlier studiesto mothers of premature infants. Thirty-two mothers of prematureinfants viewed four videotapes of 9-month-old full-term infants,each labeled either full-term or premature and either male orfemale. When infants were labeled premature the mothers perceivedthem as littler, finer featured, weaker, more passive, and slowerthan infants labeled full-term. The mothers also perceived labeledboys as bigger than labeled girls. Differences in stereotypingbetween the mothers in this study and both mothers of full-terminfants and college students are identified and discussed. Resultssuggest that mothers of premature infants expect deficits inpremature infants' physical development but not in prematureinfants' mental or social development. The likely sources andpossible self-fulfilling nature of these biased perceptionsare considered 相似文献

BACKGROUND: Limited knowledge exists regarding the neurobiology of trichotillomania (TTM). Cerebellum (CBM) volumes were explored, given its role in complex, coordinated motor sequences. METHODS: Morphometric magnetic resonance imaging (MRI) scans were obtained for 14 female subjects with DSM-IV diagnoses of TTM and 12 age-, education-, and gender-matched normal control (NC) participants. Parcellation was performed utilizing a recently developed methodology to measure subterritory volumes of the CBM. Regions were defined based on knowledge of the structural and functional subunits of the CBM. RESULTS: As predicted, significant group differences were reported for CBM raw cortical volumes (p = .008) that survived correction for total brain volume (TBV; p = .037) and head circumference (HC; p = .011). A priori and post hoc group raw volume comparisons for CBM subterritories and functional clusters revealed many significant differences. However, most differences failed to withstand correction for total CBM volumes (TCV). Smaller volumes were consistently reported for the TTM versus NC cohorts. Total Massachusetts General Hospital Hair Pulling Scale (MGHHPS) scores were significantly inversely correlated with left primary sensorimotor cluster volumes (p = .008), with smaller volumes associated with more severe TTM symptoms. CONCLUSIONS: These findings implicate the CBM in the neurobiology of TTM, with reduced subterritory volumes reported for the TTM versus NC groups. 相似文献

Depression has received increasing attention as a significant public health issue over the past ten years, both in Canada and elsewhere in the industrialized west. During the same period, many of the social and economic policies adopted by governments in these jurisdictions have reflected neoliberal goals and orientations. The purpose of this article is to explore the points of contact between these two features of contemporary social and political life in the industrialized west, using the Canadian province of British Columbia as an empirical site. My analysis draws on the Foucauldian literature on governmentality in presenting a close reading of provincial government documents concerned with depression and mental health literacy that have been produced since the election of the Liberal Party to office in British Columbia in 2001. This analysis identifies discourses of “responsibilization” circulating in these documents, within which individuals, families, communities and workplaces – rather than publicly-funded services – appear as key resources in responding to experiences of mental distress. It also points to a number of strategies visible in the documents that work to align the interests of individuals and their practitioners in pursuing particular approaches to treatment with a governing interest in reducing public spending on services and supports. The article concludes by identifying a number of resistive discourses and proposing further research in a range of empirical contexts within which they may be evident. 相似文献

PURPOSE: We undertook a feasibility study to explore the prevalence of preoperative and postoperative lower urinary tract symptoms (LUTS) in older adults undergoing elective hip arthroplasty and to determine whether a larger prospective study was warranted. METHOD: Subjects awaiting elective hip arthroplasty were recruited preoperatively from an orthopedic office and preadmission clinic at 1 university-affiliated hospital. LUTS and related quality of life were measured prehospitalization and 6 weeks postoperatively using the American Urological Association Symptom Index and quality-of-life score. Postvoid residual urine and the 24-hour pad test were used to assess bladder emptying and continence status. RESULTS: Sixteen participants (9 males, 7 females, mean age 74 years) completed the study. Preoperatively, 15 participants reported at least 1 symptom and none had discussed these with a healthcare professional. The most common LUTS were nocturia, frequency, and urgency. Postoperatively, all reported symptoms, with 8 (53%) experiencing increased symptoms with a negative impact on quality of life for 3. Recruitment was a major barrier in conducting the study and would need to be taken into account in further studies of the topic. CONCLUSION: Despite recruitment issues, we suggest larger studies of LUTS in older adults undergoing surgery are warranted to further understand potential problems and risks in transition from hospital to home. Future studies should include identification of potential reasons for increased LUTS, including urinary tract infection. 相似文献
