Nationally representative studies estimate that almost one in five adolescents in the United States is overweight. This is a major concern for individuals' physical and psychological health and the overall economy in terms of health care costs and loss of productivity. A 12- to 14-year-old subsample of 4,688 adolescents from the NLSY97 cohort was used to address the association between family processes, demographic variables, and adolescent body mass index (BMI) percentile over 4 years. The final model indicated that frequency of family meals, gender, race, control, and mothers' BMI were important predictors of adolescent BMI percentile over time. Mothers' BMI was the strongest predictor of adolescent BMI percentile. More frequent family meals led to decreases in BMI percentile over time, whereas males, African Americans, and Latinos had higher average BMI percentiles than other groups. 相似文献

Abstract Objective: To identify college presidents’ support for tobacco-free campus policies (TFCP), perceived barriers and benefits to implementing such policies, and activities that might initiate policy adoption. Participants: Participants were 405 presidents (51% of 796 delivered surveys) from a national sample of eligible 4-year institutions in summer 2012. Methods: A 4-page, 24-item cross-sectional questionnaire was mailed to potential participants in 4 waves to maximize the response rate. Results: The vast majority of presidents support TFCP (84%) and believed they should play a key role in establishing TFCP (80%). A majority agreed advocacy by campus groups was necessary to establishing TFCP. Presidents with an existing policy were twice as likely to believe advocacy was necessary for policy establishment. Presidents most commonly selected creating policy drafts and designating a committee as important to initiating TFCP. Conclusion: Advocates would benefit from focusing on presidential involvement and solutions to personnel barriers in establishing TFCP. 相似文献

How does an ideology such as populism persist and shift across generations? How do people come to embody such an ideology? This article focuses on a grassroots community association to illustrate how enduring ideologies are culturally produced and transformed. Drawing on oral history interviews and field research with an organization of Kentucky small-scale family farmers, and drawing on Holland and Lave's (2001) concept of history-in-person, I argue that enduring ideologies and attendant identities persist and shift through contentious confluences of individual biographies, citizen's groups, and societal institutions. I contend that the history-in-person approach informed by experience-near data offers an insider's view useful to explaining how durable and contentious ideologies and identities persist and change over time. 相似文献

Previous research has found a positive relationship between marriage and infant health, but it is unclear whether this relationship is causal or a reflection of positive selection into marriage. We use multiple empirical approaches to address this issue. First, using a technique developed by Gelbach (2009) to determine the relative importance of observable characteristics, we show how selection into marriage has changed over time. Second, we construct a matched sample of children born to the same mother and apply panel data techniques to account for time-invariant unobserved characteristics. We find evidence of a sizable marriage premium. However, this premium fell by more than 40 % between 1989 and 2004, largely as a result of declining selection into marriage by race. Accounting for selection reduces ordinary least squares estimates of the marriage premiums for birth weight, prematurity, and infant mortality by at least one-half. 相似文献

We reexamine Rosenfeld’s (2010) study on the association between child outcomes and same-sex family structure. Using the same data set, we replicate and generalize Rosenfeld’s findings and show that the implications of his study are different when using either alternative comparison groups or alternative sample restrictions. Compared with traditional married households, we find that children being raised by same-sex couples are 35 % less likely to make normal progress through school; this difference is statistically significant at the 1 % level. 相似文献

Challenging the standard reasoning regarding leaders' ethical failures, we argue that a potent contributor to these failures is the social role expectations of leaders. We maintain that leaders' central role expectation of goal achievement contributes to the over-valuing of group goals and greater moral permissibility of the means used to achieve these goals. In studies 1 and 2 we demonstrated that the role of leader, relative to group member, is associated with an increased appraisal of group goals which is predicted by the leaders' role expectations and not driven by the psychological effects of power. Next, we experimentally demonstrated the importance of both role expectations of leadership and group goal importance in leaders' justification to engage in morally questionable behavior to achieve group goals. Finally, we supported the social role predictions in a laboratory experiment by assigning people to roles and assessing goal importance and unethical decision-making and behaviors. 相似文献

Exploring the economic and social determinants of psychological well-being and perceived social support in England 总被引:5,自引:0,他引:5

Summary. A fundamental focus of Government concern is to enhance well-being. Recently, policy makers in the UK and elsewhere have recognized the importance of the community and society to the well-being of the nation as a whole. We explore the extent to which economic and social factors influence the psychological well-being of individuals and their perceptions of the social support that they receive, using Health Survey for England data. We employ a random-effects ordered probit modelling approach and find that unobserved intrahousehold characteristics help to explain the variation in our dependent variables, particularly for co-resident females. Our results indicate that individuals with acute and chronic physical illness, who are female, unemployed or inactive in the labour market and who live in poor households or areas of multiple deprivation report lower levels of psychological well-being. Reduced perceptions of social support are associated with being male, single or post marriage, from an ethnic minority, having low educational attainment and living in a poor household, but are not statistically related to area deprivation measures. These findings may help to inform the contemporary policy debate surrounding the promotion of individual well-being and community, through the alleviation of social exclusion. 相似文献

The modern world has influenced the approach to empirical modeling and consequently the approach to methodology in general. The question of whether to base a model on an economic theory is easier when several models can be constructed, but an empirical evaluation analysis is required. Starting with a widely specified model and using a reduction procedure is currently a popular process; it is unclear if the reduction should be to a single or to a few alternatives. New methodologies are required for conditional predictive distributions, which are the models of the future. 相似文献

Exposure duration is an important component in determining long-term dose rates associated with exposure to environmental contaminants. Surveys of exposed populations collect information on individuals' past behaviors, including the durations of a behavior up to the time of the survey. This paper presents an empirical approach for determining the distribution of total durations that is consistent with the distribution past durations obtained from surveys. This approach is appropriate where the rates of beginning and ending a behavior are relatively constant over time. The approach allows the incorporation of information on the distribution of age in a population into the determination of the distribution of durations. The paper also explores the impact of "longevity" bias on survey data. A case study of the application of this approach to two angler populations is also provided. The results of the case study have characteristics similar to the results reported by Israeli and Nelson ( Risk Anal. 12, 65-72 (1992)) from their analytical model of residential duration. Specifically, the average period of time for the total duration in the entire population is shorter than the average period of time reported for historical duration in the surveyed individuals. 相似文献
