Yearlong physical activity and health-related quality of life in older Japanese adults: the Nakanojo Study

We hypothesized that the health-related quality of life (HRQOL) would be poorer in physically inactive older adults. This was tested in a sample of 73 male and 108 female free-living healthy Japanese participants, age 65-85 years. We measured accelerometer step counts and their metabolic equivalents (METs) throughout each 24-hr period for 1 year. At the end of the year, HRQOL was assessed. Physical activity was grouped into quartiles. HRQOL was poorer in the lowest quartiles of participants with respect to both step count and duration of activity >3 METs; however, our sample showed no better HRQOL in those participants exceeding minimum standards of daily physical activity, corresponding to counts of around 5,500 and 4,500 steps/day and durations of around 13 and 14 min/day in men and women, respectively. Causation cannot be demonstrated from this cross-sectional study, but nevertheless we suggest that elderly individuals should be encouraged to meet such standards of habitual physical activity.     

The impact of high-calorie-expenditure exercise on quality of life in older adults with coronary heart disease

The acceptability of a high-calorie-expenditure (HCE) exercise program in older coronary heart disease patients participating in a behavioral weight-control program was evaluated. Seventy-four overweight patients (median age 63 yr) were randomly assigned to a 5-mo intervention of HCE exercise (3,000-3,500 kcal/wk daily walking) or standard cardiac-rehabilitation (CR) exercise (700-800 kcal/wk). Both groups received counseling to achieve a dietary caloric deficit of 3,500 kcal/ wk. Assessments at baseline and 5 mo included self-reported measures of quality of life and psychosocial variables. The HCE group experienced significantly greater weight loss (8.2 ± 4 vs. 3.7 ± 5 kg, p < .001). Changes from baseline to 5 mo on scores of physical, emotional, and social functioning were greater for the HCE than CR group (p < .05). HCE exercise also resulted in greater positive change in exercise enjoyment (p = .05), which was mediated by weight change. Even high-risk older adults can be successful in an HCE exercise program and experience no adverse physical or emotional changes.     

Endurance exercise and leg strength in older women

Quadriceps strength and mass peak in the third decade of life, plateau, and then decline from the fifth decade on. To examine the influence of chronic endurance training and age on lean mass and leg strength, women runners (n = 62, age 43-69 years) and sedentary participants (n = 33, age 43-66 years) were divided into 40-, 50-, and 60-year age groups. Absolute isokinetic concentric torque did not differ between runners and sedentary women (97.9 +/- 19.5 and 104.6 +/- 22.7 N . m, respectively, p = .18) but was different between age groups independent of exercise status (107.6 +/- 18.4, 97.1 +/- 19.9, and 90.1 +/- 21.4 N . m, for 40s, 50s, and 60s, respectively, p < .05). Lean body mass also differed by age group (p < .05) but did not change differently among runners and sedentary women. These findings suggest that chronic endurance training might not influence the loss of muscle mass and muscle strength that occur with aging.     

The effects of respiratory-muscle training on exercise in older women

This research examined the effects of respiratory-muscle (RM) training on RM function and exercise performance in older women. Twenty-six women (60-69 yr of age) were assessed for spirometry, RM strength (maximal inspiratory and expiratory pressure), inspiratory-muscle endurance, and walking performance to a perceived exertion rating of "hard." They were randomly allocated to a threshold RM training group (RMT) or a nonexercising control group (CON) for 8 wk.After training, the 22% (inspiratory) and 30% (expiratory) improvements in RM strength in the RMT group were significantly higher than in the CON group (p < .05). The RMT group also displayed several significant performance improvements, including improved within-group treadmill performance time (12%) and reductions in submaximal heart rate (5%), percentage of maximum voluntary ventilation (16%), and perceived exertion for breathing (8%). RM training appears to improve RM function in older women. Furthermore, these improvements appear to be related to improved submaximal exercise performance.     

School bullying and health-related quality of life in Chinese school-aged children and adolescents

To explore the association between bullying and HRQoL among Chinese school-aged children and adolescents utilizing a cross-sectional survey design. Bivariate associations were used to determine the correlation between the experience of bullying and lower HRQoL, and multivariate logistic regressions were evaluated. A total of 2,155 participants, 32.57%, reported experiencing bullying: traditional bullying, 27.80% (n = 599) (β = −3.55, p < .001, SE = 0.41), and cyberbullying, 7.47% (n = 161) (β = −2.50, p < .001, SE = 0.71). The degree of traditional bullying (β = −10.28, p < .001, SE = 1.19) was negatively significantly associated with HRQoL. Other determinants of the impact of the bullying in this cohort were the children's school performance and their relationship with parents, teachers and classmates.     

The effects of life events and interpersonal loss on exercise adherence in older adults

Associations of life events and interpersonal loss with participation in home- and group-based exercise were studied in 97 older adults (64 % women, 70.2 +/- 4.1 years). Life events were assessed with a modified Social Readjustment Rating Scale at baseline and 6 and 12 months. Exercise logs and class-attendance records documented exercise participation. Participants experienced 3.62 +/- 3.56 unique life events over the course of the study, and 28 participants reported an interpersonal loss (5 men, 23 women). Number of life events was negatively associated with home-based exercise participation (p <.05); among women, this association approached significance (p =.06) for class-based exercise. Women who experienced an interpersonal loss had lower class-based participation than those who did not (p =.02), but home-based participation rates were unaffected. Life events, particularly interpersonal loss, appear to have a negative impact on exercise in women, and this effect appears greater for class-based than for home-based exercise.     

Effects of vibration exercise on muscle performance and mobility in an older population

This study was designed to investigate the effects of vibration on muscle performance and mobility in a healthy, untrained, older population. Forty-three participants (23 men, 20 women, 66-85 y old) performed tests of sit-to-stand (STS), 5- and 10-m fast walk, timed up-and-go test, stair mobility, and strength. Participants were randomly assigned to a vibration group, an exercise-withoutvibration group, or a control group. Training consisted of 3 sessions/wk for 2 mo. After training, the vibration and exercise groups showed improved STS (12.4%, 10.2%), 5-m fast walk (3.0%, 3.7%), and knee-extension strength (8.1%, 7.2%) compared with the control (p < 0.05). Even though vibration training improved lower limb strength, it did not appear to have a facilitatory effect on functional-performance tasks compared with the exercise-without-vibration group. Comparable mobility and performance changes between the experimental groups suggest that improvements are linked with greater knee-extension strength and largely attributed to the unloaded squats performed by both exercise groups.     

Differences in health-related quality of life among persons living with HIV/AIDS

We sought to identify differences in health-related quality of life (HRQoL) among a sample of HIV positive individuals receiving case management services in northern Florida. Our study consisted of 97 individuals receiving HIV case management that included 56 males (57.7%) and 81 African Americans (83.5%) who were 47.05 years old (SD = 9.33). HRQoL was measured using the HIV/AIDS Targeted-Quality of Life scale (HAT-QOL). Results show significant group differences in HRQoL by race, income, tobacco use, alcohol use, drug use, and CD4 cell count, despite only 43% of this sample being able to recall their most recent CD4 count. Translating these findings to inform practice, HIV care providers need to provide continuing education to patients about their disease status, knowledge, and treatment as it relates to self-care. Also, HIV care providers should be especially cognizant of the impact that tobacco, alcohol, and illicit drug use has on HRQoL for persons living with HIV/AIDS (PLHA) by working to assess social support, identify readiness for change, and make appropriate referrals for treatment.     

The experience of quality of life among older people

Although quality of life has been in the focus of attention for over a decade there are few studies available investigating, how the old and the oldest old experience their quality of life or what quality of life actually means for them? To illuminate this, eleven in-depth interviews were conducted with six women and five men (80+) living in their home. An interpretative hermeneutic phenomenological analysis revealed that quality of life in old age meant a preserved self and meaning in existence. Maintained self-image meant that the older people experienced a coherent life with an intact meaning. How quality of life was valued depended on the meaning the old people attached to the areas of importance as well as how they were evaluated. Additionally, areas not generally included when measuring quality of life became discernible. The meaning of home, how life was viewed, thoughts about death and dying, and telling ones story proved to be areas of importance for their perception of quality of life. Thus, indicating that older people's view of quality of life is more complex than some of today's most commonly used quality of life instruments capture and that quality of life assessment tools needs to measure beyond pure health indices. For nursing care the use of life review in everyday care, and an open way towards existential topics as well as a family oriented care along with preventive work helping people to remain in their own homes may enhance their experience of quality of life.     

Post-traumatic stress disorder and health-related quality of life in female victims of intimate partner violence

The association between post-traumatic stress disorder (PTSD) and health-related quality of life (QOL) in female victims of intimate partner violence (IPV) was examined. The Short-Form Health Survey (SF-36) was used to evaluate health-related QOL. IPV victims with PTSD (IPV/PTSD+; n = 18), IPV victims without PTSD (IPV/PTSD-; n = 22), and a non-abused control group (NA; n = 30) were compared. Multiple Analyses of Covariance (covarying for socioeconomic status and age) indicated that the three groups scored significantly differently on health-related QOL, and the IPV/PTSD- group was significantly more impaired than the NA group. IPV/PTSD+ subjects were significantly more impaired than IPV/PTSD- subjects on physical functioning, mental health, vitality, role limitations due to emotional health, and social functioning. Multiple regression analyses indicated that PTSD severity was a significant statistical predictor of SF-36 mental health composite scores (but not of physical health composite scores), after controlling for depressive symptomatology and extent of physical and psychological abuse.     

Narratives and self-identity in later life: Two rural American older women

Older adults often draw on memories to construct stories about themselves that help them to retain and validate their self-identities, doing this within the cultural contexts that have shaped their lives. In this paper, we examine the life history narratives of two working class, rural American older women and the ways in which those narratives are similar despite one major difference: one has dementia. In both cases, major themes that are consistent with gender-based, working class, rural American cultural values are dominant, including closeness of family, hard work, ties to the land, and religious faith. In the first case, she reconstructs memories of her life in accordance with dominant cultural and personal values, downplaying the ways in which her experiences were “out of step” with these values. In the second case, her sense of identity remains and is expressed through her co-constructed memories although she is experiencing cognitive loss.     

Oral health-related quality of life improves in employees with disabilities following a workplace dental intervention

This pilot study evaluated a dental intervention for employees with disabilities by measuring changes in self-rated oral health, dental behaviours and oral health-related quality of life (OHRQol). Consenting employees with disabilities (≥18 years) at two worksites in South Australia underwent dental examinations at baseline, three and six months. Referrals were arranged as needed to public dental clinics. At one and two months a dental hygienist provided group oral health education to the employees. Employees’ demographics, self-rated oral health, dental behaviours and OHRQol were collected via face-to-face interviews. Of the 39 referred employees, 28 (72%) of them completed the recommended treatment. Self-rated oral health improved and there were significant reductions in the prevalence of oral health impact on quality of life (percentage of employees reporting 1+ items fairly/very often) from 27% to 11% (McNemar’s test, p < 0.05); the extent of impact (mean number of items reported fairly/very often) from 1.3 to 0.6 and the severity of impact (mean of summed OHIP item scores) from 3.6 to 1.8 (paired t-tests, p < 0.01). As this pilot study indicates that enabling urgent referral for treatment and regular oral health education can improve OHRQol and self-rated oral health among employees with disabilities, a larger study with a control group should be undertaken.     

Reflections of older Iranian women: Adapting to life in the United States

Age is an important and often overlooked attribute that influences adjustment to a new cultural context. This paper focuses on the ways in which older Iranian women, who spent their youth and middle adult years in Iran, have adapted to life in the United States. The results are based on extensive interviews with 19 Iranian women over the age of 65 (age range was 65 to 85). Although the majority of women interviewed expressed positive feelings about themselves and a sense of satisfaction with the transitions in their lives, considerable individual differences were identified. These differences focused primarily on the ways in which they attempted to adapt or cope with the new cultural environment in which they were living. Analysis resulted in the identification of three general strategies of adaptation to immigration. These strategies were labeled as withdrawn, insular, and assimilative.     

Role and function: Aspects of quality of life of older people in rural Bangladesh

The aim of this study is to explore the meaning of quality of life (QoL) for elderly people in a rural community in Bangladesh. Data were obtained through in-depth interviews with 11 elderly persons aged 63–86 years. Interview data were analysed using content analysis to determine the conceptual meaning of elderly peoples' experiences of QoL. Two major themes emerged from the data as being of utmost importance in QoL of elderly people in rural Bangladesh. These were: (i) having a role in the family and the community and (ii) being functional, both physically and economically. Results also showed that elderly people in rural Bangladesh prioritise being healthy, having a good social network, social support and a secure financial situation in order to have good QoL. This study is a step towards a better understanding of QoL experienced by the elderly people themselves in a rural Bangladeshi context.     

Health-related quality of life in older adults: Testing the double jeopardy hypothesis

The double jeopardy hypothesis posits that racial minority elderly suffer a double disadvantage to health due to the interactive effects of age and race. Empirical examinations have found mixed support for the proposition that the aging process heightens the health disadvantage for racial minorities compared to whites. Race-by-age differences are tested using a health-related quality of life measure that has been largely overlooked in previous double jeopardy analyses. The outcome, number of days in poor physical health during the past month, quantifies day-to-day physical well-being in a way not available to standard measures of morbidity and mortality. The data are from the 2003 California Health Interview Survey (CHIS) and were analyzed using negative binomial regression. Results show that the magnitude of differences in the number of physically unhealthy days for African Americans and Hispanics compared to their white counterparts is much larger in the elderly strata than that observed between younger groups. Additionally, social characteristics do not fully explain why racial differences in poor physical health days are greater at older ages. A life course perspective is proposed as one possible explanation for the double jeopardy finding. The results indicate a need to consider health-related quality of life outcomes when examining racial/ethnic health disparities among the elderly population. The appendix presents cross-validation of the 2003 CHIS results with the 2005 CHIS and the findings are replicated.     

Predictors of falling in older Maryland drivers: a structural-equation model

Falls can impair health and reduce quality of life among older adults. Although many factors are related to falling, few analyses examine causal models of this behavior. In this study, factors associated with falling were explored simultaneously using structural-equation modeling. A variety of cognitive, physical-performance, and health measures were administered to 694 older adult drivers from the state of Maryland. The observed and latent variables of age, cognitive ability, physical functioning, health, and falling behavior were used to create a causal model. The model revealed that being older was associated with declines in cognition, and such cognitive declines predicted increased falling. Similarly, poorer health was related to poorer physical functioning, which, in turn, also predicted increased falling. This model indicates that in addition to existing fall-prevention interventions aimed at improving physical functioning, interventions to improve cognition and health might also be effective. It is speculated that fear of falling, which often results in reduced mobility among older adults, might account for the lack of a direct relationship between age and falling. This hypothesis should be examined in further research.     

Effects of exercise training with weighted vests on bone turnover and isokinetic strength in postmenopausal women

The effects of 12 wk of exercise training using weighted vests on bone turnover and isokinetic strength were evaluated in postmenopausal women randomly assigned as exercisers (EX; n = 9) or controls (CON; n = 7). Training included 3 multimodal exercise sessions per wk wearing weighted vests. The vest load was progressively increased each wk to a maximum of 15% of body weight. Bone turnover was determined from resting levels of serum osteocalcin and NTx. Knee and ankle strength were measured at 60 degrees/s and 180 degrees/s using an isokinetic dynamometer. After 12 wk, NTx decreased by 14.5% (P 相似文献
