Although much has been learned about the global determinants of physical activity in adults, there has been a lack of specific focus on gender, age, and urban/rural differences. In this church-based community sample of Appalachian adults (N = 1,239), the primary correlates of physical activity included age, gender, obesity, and self-efficacy. Overall, 42% of all participants and 31% of adults age 65 years or older met recommended guidelines for physical activity, which suggests that most participants do not engage in adequate levels of physical activity. Of participants who met physical activity guidelines, the most common modes of moderate and vigorous activity were walking briskly or uphill, heavy housework or gardening, light strength training, and biking. These particular activities that focus on building self-efficacy might be viable targets for intervention among older adults in rural communities. 相似文献

AbstractLGBTQ+?people face multiple challenges to parenthood because of barriers such as discriminatory legislation and policies influencing foster parenting, adoption, and reproductive health services. This study documents these obstacles and examines their impact through a grounded theory analysis of interviews of LGBTQ+?prospective parents. Stressors included social isolation, unnecessary medicalization, prohibitive financial costs related to accessing social and medical services (sometimes across state lines), and being denied services, parental leave, and insurance coverage. Findings indicate that heteronormative attitudes and discrimination can lead to debilitating and enduring harm upon the economic, emotional, and relational well-being of growing LGBTQ+?families. 相似文献

Parametric models for interval censored data can now easily be fitted with minimal programming in certain standard statistical software packages. Regression equations can be introduced, both for the location and for the dispersion parameters. Finite mixture models can also be fitted, with a point mass on right (or left) censored observations, to allow for individuals who cannot have the event (or already have it). This mixing probability can also be allowed to follow a regression equation.Here, models based on nine different distributions are compared for three examples of heavily censored data as well as a set of simulated data. We find that, for parametric models, interval censoring can often be ignored and that the density, at centres of intervals, can be used instead in the likelihood function, although the approximation is not always reliable. In the context of heavily interval censored data, the conclusions from parametric models are remarkably robust with changing distributional assumptions and generally more informative than the corresponding non-parametric models. 相似文献

Social network contacts—the people who are asked to help with others’ job searches—are key players in the job networking process. Before job seekers can become employed with the help social networks, contacts must first be able and willing to share the social resources job seekers need for their search. Little is known about the factors that affect contacts’ ability and willingness to do this. Analyses of a unique dataset of contacts show that they typically have access to resources and help job seekers by sharing them. Still, contacts are better able to help when they are male, employed, and better educated than job seekers. They are more willing to help when they perceive job seekers to be “good” workers. In identifying the conditions in which contacts provide social resources, this study illustrates how social networks are a productive job search strategy for some, but not all, job seekers. 相似文献

Objectives: The purpose of this study is to explore barriers to the use, maintenance, and expansion of social supports in older adult methadone clients. Methods: The data for this analysis were derived from a qualitative study of the needs of aging methadone clients. Data were collected through face-to-face interviews with 24 methadone clients over the age of 50. Results: A lack of trust was identified as a principal barrier to the use, maintenance, and expansion of the social supports of older adult methadone clients. Causes of this mistrust include issues associated with aging, past traumatic experiences, and difficult personal relationships. Implications: These findings imply that addressing the issue of self isolation and recognizing the reason older adult methadone clients engage in this behavior is a key element in getting this specific population to use, maintain, and foster healthy social supports. A common phrase echoed throughout the interviews is that a person cannot trust anybody. Because of this mistrust, some clients keep to themselves by electing to self-isolate and decline to use, maintain, or foster new relationships. As a result, these individuals are less likely foster and/or engage in healthy social relationships, which are a key component of substance abuse treatment and abstinence maintenance. 相似文献
