Background

Previous physical activity (PA) tracking studies have examined the stability of overall PA and/or PA types, but few have investigated how specific types of sport/exercise track over the life course. The aim of this study was to determine how specific sports/exercises in midlife track and predict future sport/exercise and PA in men transitioning to old age.

Methods

Seven thousand seven hundred thirty-five men (aged 40–59?years) recruited in 1978–80 were followed up after 12, 16 and 20?years. At each wave men self-reported participation in sport/exercise. Frequent sport/exercise participants (>?1/month) reported the types of sport/exercise they engaged in. Men also reported total PA, health status, lifestyle behaviours and socio-demographic characteristics. Stability of each sport/exercise was assessed using kappa statistics and intraclass correlation coefficients. Logistic regression estimated the odds of participating in sport/exercise and being active at 20-year follow up according to specific types of sport/exercise in midlife.

Results

Three thousand three hundred eighty-four men with complete data at all waves were included in analyses. Tracking of specific sports/exercises ranged from fair to substantial, with golf being the most common and most stable. Bowls was the most frequently adopted. Odds of participating in sport/exercise and being active in old age varied according to sport/exercise types in midlife. Golf and bowls in midlife were the strongest predictors of sport/exercise participation in old age. Golf, cricket and running/jogging in midlife were among the strongest predictors of being active in old age. Compared to participating in just one sport/exercise in midlife, sampling multiple sports/exercises was more strongly associated with sport/exercise participation and being active in old age.

Conclusion

The stability of sport/exercise participation from midlife to old age varies by type. Specific sports/exercises in midlife may be more likely to predict future PA than others. However, participating in a range of sports/exercises may be optimal for preserving PA into old age.

Among their many responsibilities, foster parents are tasked with providing healthy food and proper nutrition to children with a variety of physical, psychological, and emotional needs. Using the lens of symbolic interactionism, this exploratory mixed methods study examined how foster parents attend to the nutritional needs of abused and neglected children. Methods used included both quantitative surveys and qualitative follow-up interviews. Surveys were completed by 23 foster parents in a large, Midwest metropolitan area. Parents reported they provided their children balanced meals, although one-third of households reported instances of food insecurity. During qualitative interviews, foster parents (N = 9) described how children arrived at their home with a variety of unhealthy eating habits, some severe in nature. Parents discussed strategies used to modify and improve eating patterns, including offering healthy food choices, having children plan meals, and gathering as a family for daily dinners. In general, parents understood the link between unhealthy eating and past childhood trauma, but also reported being unprepared for more serious eating problems like hoarding. Findings indicate that foster parents need food assistance to increase food security as well as training in assessing and responding a variety of unhealthy child eating behaviors.  相似文献

As a society, we've made tremendous progress toward gender equality over the past several decades. Yet there remains significant inequality between women and men. Furthermore, when we look closely at some of the progress made toward gender equality, we find it considerably less impressive than surface appearances. In this article, we review the updated framework of Risman's (2017) gender structure theory and argue that it can help us make sense of the progress we've made as well as analyzing inequality as it persists between women and men. Using gender structure theory, we then show how gender is simultaneously reproduced and contested across the individual, interactional, and macro levels of society within 3 major social domains: work, family, and gender identity.  相似文献

Previous research suggests that an increasing age at first marriage has contributed to the prevalence of sexual hookups on U.S. college campuses. In this article, we use life course and marital horizons theories to analyze the influence of ideal age at first marriage on hooking up among unmarried heterosexual college students. Analyses of the Online College Social Life Survey (N = 17,981) show a positive association between ideal age at first marriage and hookups for most students, but not for students whose mothers have no post‐secondary education, Asian men, Asian women, and Latina women. Variation in ideal marriage timing does not account for gender, racial/ethnic, and class gaps in hookup participation. Results are discussed with reference to the role of sexuality in processes of stratification throughout young adulthood.  相似文献

ABSTRACT

Despite the fact that Aboriginal and Torres Strait Islander communities typically experience a high prevalence of sexual and family violence, service responses have mostly been culturally inappropriate and ineffective. This article reports on a collaborative, participatory research project aimed at exploring barriers to service access by Aboriginal and Torres Strait Islander clients when they have been affected by sexual and family violence. The findings reveal multiple barriers to service access, including justice system deterrents, social taboo, shame, and a lack of culturally appropriate services. The article highlights the importance of recognising and addressing the complex interplay of historic, social, and cultural factors influencing service access.  相似文献

The authors examined how mothers' and fathers' feelings of competition at home and work affect their relationships with their daughters and sons using time‐diary data from a national sample of 220 families. Multivariate analyses revealed 3 relationships between parents' feelings of competitiveness at work and home and feelings of competition experienced by their children at school and home: (a) parents' and adolescents' competitiveness varied across home, work, and school—with mothers and fathers reporting similar levels of competition at work but daughters feeling more competitive at school than sons; (b) parents' competition at work was associated with similar activities; however, daughters' and sons' competition at school varied by activities; and (c) mothers' competition was associated with strategies for college enrollment and varied by gender, most notably with respect to daughters' academic progress. The results suggest how parents' competitive disposition may motivate their children's academic performance, especially between working mothers and their daughters.  相似文献

Most cities, counties, and neighborhoods are not designed for an aging population. By providing a range of services to all residents, Lifelong Communities allow individuals to age in place. Although the Lifelong Communities Initiative is based on established guiding principles, little information exists regarding the realities of moving from policy to implementation. The Atlanta Regional Commission conducted a case study in Mableton, Georgia, and found successful implementation requires a combination of support from local citizen groups and government. The Atlanta Regional Commission is replicating these best practices in other communities and providing support to those aspiring to launch or expand Lifelong Communities.  相似文献
