This single-group repeated-measures pilot study evaluated the effects of a 10-wk, multicomponent, best-practice exercise program on physical activity, performance of activities of daily living (ADLs), physical performance, and depression in community-dwelling older adults from low-income households (N = 15). Comparison of pretest and posttest scores using a one-tailed paired-samples t test showed improvement (p < .05) for 2 of 3 ADL domains on the Activity Measure-Post Acute Care and for 6 physical-performance measures of the Senior Fitness Test. Repeated-measures ANOVA revealed significant main effects for 3 of 8 physical activity measures using the Yale Physical Activity Scale. Retention rate was 78.9%, and the adherence rate for group sessions was 89.7%. Results suggest that participation in a multicomponent, best-practice physical activity program may positively affect sedentary, community-dwelling older adults' physical activity, ADL performance, and physical performance.  相似文献

Major league baseball career length in the 20th century   总被引:1,自引:0,他引:1  
The sport of baseball has used statistics to enhance understanding for fans for over a century, yet there is limited data on player careers. This study fills that void by examining the careers of baseball players over the last century. Between 1902 and 1993, 5,989 position players started their careers and played 33,272 person years of major league baseball. A rookie position player can expect to play 5.6 years; one in five position players will have only a single-year career, and at every point of a player’s career, the chance of exiting is at least 11%. Position players who start younger and begin their careers in more recent decades all have longer and more stable careers; nevertheless, baseball careers are not compressed versions of normal careers, but are substantially skewed toward early exit.

Although cigarette smoking has been extensively researched, surprising little knowledge has been produced by demographers using demographic perspectives and techniques. Thus, this paper contributes to the literature by extending a demographic framework to an important behavior for mortality research: cigarette smoking. In earlier works, the authors used nationally-representative data to show that cause of death patterns varied by smoking status and that multiple causes of death characterized smokers moreso than non-smokers. The present work extends previous analysis by estimating smoking status mortality differentials by underlying and multiple causes of death and by age and sex. Data from the 1986 National Mortality Followback Survey are related to data from the 1985 and 1987 National Health Interview Survey supplements to assess the smoking-related mortality differentials. We find that cigarette smoking is associated with higher mortality for all population categories studied, that the smoking mortality differentials vary across the different smoking status categories and by demographic group, and that the mortality differentials vary according to whether underlying cause or multiple cause patterns of death are examined. Moreover, the multiple cause analysis highlights otherwise obscured smoking-mortality relations and points to the importance of respiratory diseases and cancers other than lung cancer for cigarette smoking research.  相似文献

We use recently released, nationally representative data from the National Health Interview Survey-Multiple Cause of Death linked file to model the association of religious attendance and sociodemographic, health, and behavioral correlates with overall and cause-specific mortality. Religious attendance is associated with U.S. adult mortality in a graded fashion: People who never attend exhibit 1.87 times the risk of death in the follow-up period compared with people who attend more than once a week. This translates into a seven-year difference in life expectancy at age 20 between those who never attend and those who attend more than once a week. Health selectivity is responsible for a portion of the religious attendance effect: People who do not attend church or religious services are also more likely to be unhealthy and, consequently, to die. However, religious attendance also works through increased social ties and behavioral factors to decrease the risks of death. And although the magnitude of the association between religious attendance and mortality varies by cause of death, the direction of the association is consistent across causes.  相似文献

We investigate the effects of increases in married women's actual income and in their proportion of total family income on marital happiness, psychological well‐being, and the likelihood of divorce. We use data from a sample of 1,047 married individuals (not couples) in medium‐duration marriages, drawn from a five‐wave panel survey begun in 1980 and continuing to 1997. Structural equation modeling is used to assess the impact of increases in married women's absolute and relative income from 1980 to 1988 on the marital happiness and well‐being of married men and women in 1988. Event history analysis is used to determine how these changes affect the risk of divorce between 1988 and 1997. We find that increases in married women's absolute and relative income significantly increase their marital happiness and well‐being. Increases in married women's absolute income generally have nonsignificant effects for married men. However, married men's well‐being is significantly lower when married women's proportional contributions to the total family income are increased. The likelihood of divorce is not significantly affected by increases in married women's income. Nevertheless, increases in married women's income may indirectly lower the risk of divorce by increasing women's marital happiness.  相似文献

This paper offers a conceptually informed analysis of fostering and adoption social work and argues for more consistent inclusion of trans and non‐binary people. The conceptual framework through which we explore current policy and practice is set out to provide clarity about the ways in which we employ the concepts of trans, gender diversity, and cisgenderism (a prejudicial ideology). We employ the notion of cisgenderism as a critical lens through which to overview fostering and adoption social work within the context of trans inclusion. Focus is turned to the existing literature relevant to trans parenting, trans‐headed families, and the field of fostering and adopting. We highlight significant knowledge gaps in this regard. We then argue that if fostering and adoption social work is to embody inclusive practice with trans people, a new culture must be embedded to promote collaborative working, enhance knowledge, and improve service provision. The paper concludes by asserting that such an approach must be underpinned by an understanding, acceptance, and appreciation of people who identify as trans and/or as non‐binary.  相似文献

Electronic gambling machines (EGMs) show a strong association with gambling problems. The high speed of gaming offered by modern EGMs allows playing numerous games in a short span of time, which is thought to contribute to attentional distraction, increased spending and prolonged play. However, the relationship between EGM speeds and potentially risk-related gambling behavior remains unclear. We introduce a novel approach to investigating the role of gaming speed in EGM gambling behavior by examining ‘individual rate-of-play’ (I-ROP) during simulated EGM gambling. A community sample of male regular gamblers (N = 72) played virtual slot machines in pairs offering sequentially adjusted game speeds towards the estimation of a behaviorally expressed preference speed, or I-ROP. This initial experiment aimed to explore the variability of I-ROPs during simulated EGM gambling, and examine behavior while playing EGMs at speeds relative to their I-ROP. Estimated I-ROPs ranged from less than one half second to over seven seconds and were negatively associated with cognitive ability, but not related to problem gambling severity, impulsiveness, or gambling-related cognitions. Subsequent gambling sessions on EGMs offering individually calibrated faster and slower gaming speeds were associated with greater and reduced risk-related gambling behaviors respectively. I-ROPs represent a potentially informative construct for exploring influences of gaming speed on gambling behavior, and may lend insight into potential risk-related behavior an individual vulnerability with respect to commercially available EGMs that warrants additional research.  相似文献
