We explore the demographic factors contributing to China's unbalanced sex ratio at marriagable ages. We develop a stable population model of the sex ratio at marriagable ages, and compare a series of population projections with alternative underlying assumptions about the key demographic inputs. The stable population model demonstrates that several demographic factors interact to influence the sex ratio at marriagable ages, including the sex ratio at birth, population growth, the age gap of marriage partners, and the sex ratio of survival from birth to marriageable age. The population projections further demonstrate that policies that seek to reduce the sex ratio at birth and the age gap at marriage and, to a lesser extent, increase fertility would be most effective at alleviating the problem. But no demographic changes are likely to occur quickly enough to balance the sex ratio at marriagable ages in the near future.  相似文献

ABSTRACT

This study focuses on grandchildren (Generation 3 or G3) caring for grandparents (Generation 1 or G1) and uses agent-based modeling to conceptualize and test a model of two factors—capability and motivation—that may affect a G3's decision to provide care for a G1. We tested our conceptual model and found that the simulated proportion of G3 caregivers has concurrent validity with existing empirical data. In experiments conducted with the validated model, we investigated universal- and targeted-policy changes (tax credit for caregivers) and found that although the universal-policy change increased G3 caregiving overall, a policy change targeting low- and middle-income caregivers was even more successful.  相似文献

Low-income older adults living in public housing are at heightened risk for substance misuse. This study identified the prevalence of alcohol misuse among older public housing residents (n?=?187) and explored predictors of problem drinking. Including weekly drinking levels and binge drinking, 23% of the sample engaged in problem drinking behaviors. Logistic regression analysis revealed that race, gender, employment status, years smoking, and illegal drug use were significant predictors of problem drinking. No residents were receiving substance abuse treatment. As the number of older adults increase, training social workers to assess and treat alcohol misuse in older adults is critical.  相似文献

Many providers recognize the importance of creating culturally competent services for lesbian, gay, bisexual, and transgender (LGBT) older adults. Although multiple resources list steps to make professional practices more LGBT-welcoming, these resources provide no empirical data to support their recommendations. LGBT older adults (N = 327) were asked to describe what signals that a provider is LGBT-welcoming. Six of the top 10 signals related to provider behavior and suggest the importance of staff training; the balance included display of signage and rainbow flags, use of inclusive language on forms and the presence of LGBT-identified staff. Results provide evidence-based recommendations for working with LGBT older adults.  相似文献

This study examined the validity of a single-item measure of HIV risk stage of change that HIV prevention contractors were required to collect by the California State Office of AIDS. The single-item measure was compared to the more conventional University of Rhode Island Change Assessment (URICA). Participants were members of Los Angeles County-defined behavioral risk groups recruited from a mobile HIV testing program (N = 123). The study found low correspondence between participants' stage of change on the single-item and the URICA, suggesting that they do not assess the same construct, and that the single item may not provide a valid measure. The current data suggests that the single-item measure should be revised or abandoned in favor of more conventional stage-of-change measures.  相似文献

Client drop out from treatment is of great concern to the substance abuse field. Completion rates across modalities vary from low to moderate, not ideal since length of stay has been positively and consistently associated with better client outcomes. The study explored whether client characteristics shown to be related to retention were associated with treatment completion and treatment duration for a sample of 164 Latino substance users who entered a culturally focused residential program. In-person client interviews were conducted within a week of program admission. Logistic regression analysis was used to examine research questions. Clients most likely to drop out had self-reported co-occurring psychiatric diagnoses; they were 81% less likely to complete the program, suggesting that clients with mental health problems have a more difficult time remaining in residential treatment. Clients using drugs in the three months prior to entry were three and a half times more likely to be in the shorter stay group, and clients who lived in institutions prior to program entry were three times more likely to be in the longer-stay group. Factors contributing to drop out for this Latino sample were similar to those identified in the literature for non-Latino samples. Methods for addressing the needs of clients with co-occurring disorders are discussed.  相似文献

OBJECTIVE AND PARTICIPANTS: The authors examined cognitive and affective dimensions of body image of a randomized sample of 188 college men on the basis of body mass index (BMI). METHODS: They conducted chi-square tests and ANOVAs to determine differences between 4 BMI groups (underweight, normal weight, overweight, and obese) on demographics and body image measures. RESULTS: The authors found significant differences in regard to total body image (p < .001), weight or shape concern (p < .001), and body dissatisfaction (p < .001). BMI was significantly correlated with negative body image. Overweight and obese participants reported significantly higher levels of negative body image than did normal- and underweight participants. Overweight participants reported significantly higher weight and shape concerns than did underweight, normal-weight, and obese participants. In regard to body dissatisfaction, underweight, overweight, and obese participants reported significantly higher levels of body dissatisfaction than that reported by normal-weight participants. CONCLUSIONS: BMI may be an important factor in identifying potential body image disorders in college-aged men.  相似文献

As a college health educator, the author knows much about healthy behaviors. In spite of this, however, the author discusses finding herself struggling with the same problems of body image that her students express. With a variety of influences tied to negative body image, it is important that college health professionals create a plan of action for reducing the negative effects of such influences. The author proposes that health professionals take a more active role in combating body image problems by using 3 important strategies: incorporating body image into basic health curricula and classes, focusing research efforts on intervention, and exploring the use of advocacy to initiate change at the societal level.  相似文献

Recent research has demonstrated that forearm support might be preferable to working in the traditional "floating" posture for computer users. A previous field study in a call centre reported a significant decrease in discomfort following 12 weeks of using a conventional desk for forearm support. The aim of this follow up study was to determine the long-term effect (21 months post intervention) of forearm support on reported musculoskeletal discomfort in the previous sample of intensive computer users. METHODS: The follow-up sample consisted of 33 females and 2 males (59% of original group). Data were collected via self-report questionnaires and workstation assessments. RESULTS: Despite a significant reduction in discomfort for most body regions following the initial intervention, the only significant decrease in discomfort over 21 months was for the neck. Reported discomfort for all other body regions had decreased, apart from the shoulder in which there was a reported increase in discomfort. The results of this follow up study indicate that forearm support has a positive effect on the reduction of neck discomfort. The increase in shoulder discomfort indicates that a concave desk may be preferable to the conventional desk if the forearm support posture is to be adopted.  相似文献
