The purpose of the study was to determine whether resistance training (RT) or a combination of resistance and aerobic training (CT) resulted in the most improvement in measures of functional ability in functionally limited elders. Elderly adults who exhibited some limits in functional ability were randomly assigned to either a CT, RT, or control (C) group. Both RT and CT exercised three times per week for 16 weeks. At Weeks 0 and 17, participants completed six measures of strength and six functional tests. A 3 (group) x 3 (time) ANOVA with repeated measures on the time factor was used to analyze the results. CT and RT scored significantly better than C at Week 17 for biceps curl, elbow extension, chair stand, and time up the stairs. These findings demonstrate that RT and CT are both effective at increasing measures of strength and functional ability in elderly adults who begin exercise with functional limitations. 相似文献

The question, “Do you and your husband intend to have a (another) child?” has become standard on fertility surveys. It is almost always asked of the wife, but is treated as the couple’s joint intention. How reasonable is such an assumption? Do husbands’ and wives’ reports of couple intent correspond closely? Do spouses know the fertility wishes of their partners? Do they take these wishes into account when reporting couple intent? Analysis of a sample of fecund, white, urban U.S. couples shows each question answered affirmatively. Reports from either spouse appear to be good, although admittedly imperfect, indicators of couple intent. 相似文献

This paper addresses the comparability of data from eight national fertility surveys conducted in the United States between 1955 and 1980. We examine the extent to which substantive conclusions about the levels and correlates of the timing offirst birth vary across these data sources by comparing samples of women who were eligible to be included in more than one study. Results obtained from Ordinary Least Squares (OLS) and logistic regression analyses of several measures of timing indicate few study effects. Thus findings based on data from one survey can be replicated with comparable data from another. One notable exception is the relationship between contraceptive use prior to the first birth and the timing of that birth. The contraceptive variable appears to be poorly measured, leading to unstable estimates of the relationship. In general, our results suggest: (1) the feasibility of pooling data from the various surveys when modeling delayed childbearing; and (2) reasonable accuracy in assessing trends in the timing of first birth from multiple data sources. 相似文献

Extending work of Cook et al. (1999, 1996), this paper examines abortion funding cutoffs for poor women in North Carolina, a unique setting allowing for a strong quasi-experimental design. Using vital registration data and additional administrative data from North Carolina, we decompose program effects on the abortion/birth ratio into two components: coverage (i.e., the proportion of all abortions that are state funded) and substitutability (the proportion of state funded abortions that would have been births in the absence of the state program). We show that both components are crucial for understanding the effects of fund cutoffs and that both components vary by age and by race. We offer explanations for these differences. Overall, we conclude that: the North Carolina State Abortion Fund (SAF) had powerful and pervasive effects: i.e., the SAF cutoffs reduced abortions and increased births. 相似文献

In an effort to assess the level of community need and inform responsive resource allocation, Larimer County, Colorado developed a county-level index of well-being. This paper describes the development of that index including the selection of indicators and the methodology for scoring and presenting those indicators. We also present how the local community used the information and describe problems we found while aggregating indicators. Next, we show the results of evaluating our index using Hagerty et al.’s (2001, Social Indicators Research 55, pp. 1–96) 14 criteria for determining validity and usefulness of quality of life indices. The Larimer County index performed above both the “satisfactory” rating and the mean of the 22 indices evaluated using Hagerty et al.’s. We conclude that the Larimer County index is based on a solid approach that will be helpful to local policy makers. 相似文献

Gender, Values, and Environmentalism 总被引:3,自引:0,他引:3
Objective . The social psychological values altruism, self-interest, traditionalism, and openness to change are key correlates of environmental concern and proenvironmental behavior. We investigate the relationship between gender and these values to better understand gender differences in environmentalism. We consider both gender differences in value priorities (differences in mean response on value scales) and differences in the meaning of values (differences in the factor structure of values) as well. Methods . Our analysis is based on data from a random-digit dialed national telephone survey of U.S. adults conducted in 1994. We examine differences in factor structure of values for a group of 145 white men and 200 white women using confirmatory factor analysis and differences in mean value scores using multivariate analysis of variance. Results . We find no substantial differences in value factor structure, but differences in value priorities, with women ranking altruism as more important than men. Conclusions . Our analysis supports work that focuses on mean differences in environmentalism across genders without examining gender differences in factor structure, although further examination of gender differences in factor structure is warranted. Our results also highlight the importance of gender differences in altruism as a basis for gender differences in environmentalism. 相似文献

This is one of the first qualitative event-based studies to understand the various mechanisms through which multiple factors influence condom use decision making among homeless youth. Event-level interviews that explore characteristics of the environment surrounding sexual events were conducted with 29 youth who were asked to describe two recent sexual encounters. In thematic analyses of data across events, reasons that youth gave for engaging in unprotected sex included the expectation of having sex and use of alternative methods of protection against pregnancy. Other nonevent factors that influenced condom use decision making were related to attributes of the partnership (e.g., testing, trust and love, and assessments of risk) and attributes of the youth (e.g., perceptions of diseases, concerns over pregnancy, and discomfort using condoms). Additional event analyses conducted within the same individuals found that decision making was influenced by multiple interacting factors, with different pathways operating for event and nonevent factors. Future interventions should consider taking a multilevel and individualized approach that focuses on event-based determinants of risky sex in this population. 相似文献

The multiple‐family group intervention is an effective, yet affordable, 8‐week treatment that is conducted in a juvenile correctional institution in Alabama with adolescents who sexually offend and their families. Data from 115 incarcerated male adolescents and their male and female caregivers collected at pre‐, post‐, and 1‐year follow‐up were used to determine that problem behaviors (internalizing, externalizing) decreased over pre‐ and posttest and the significant decreases in maladaptive emotion regulation predicted those changes. Adolescent‐reported anxiety over abandonment and attachment dependence on parents increased significantly; these changes were predicted by decreases in maladaptive emotion regulation. Linear growth models were also fit over the 3 time points and indicate decreases in adolescent problem behavior and maladaptive emotion regulation. 相似文献
