Over a third of American college students are either overweight or obese, which has been suggested to negatively impact their academic achievement. Objective: This study seeks to better understand the relationship between body mass index (BMI) and grade point average (GPA), while examining potential mediators of this association. Participants and Methods: The sample consists of 298 college women who volunteered to complete online questionnaires between October and December 2014. Results: Although no significant differences were noted for sociodemographic variables, overweight and obese female students were found to report lower GPA and academic self-efficacy as well as higher depressive symptoms, compared with their normal-weight counterparts. Academic self-efficacy partially mediated the relationship between BMI and GPA. Conclusions: To foster better academic achievement in female college students, and especially for those who are overweight and obese, strategies for improving self-efficacy and adaptation to college should be implemented.  相似文献

This article reports findings among adolescents of the impact of Well London, a program of wellbeing interventions delivered across 20 deprived neighbourhoods of London using a community engagement model. Twelve hundred and fifty-four adolescents were surveyed from matched intervention and control areas. There was no significant intervention effect on the main outcome measures: unhealthy eating, physical activity, and mental health. Factors influencing the results may include the possibility that the communities defined by the cluster randomized controlled trial (CRCT) were not an accurate reflection of the adolescent’s natural community, and interactions within the school environment in particular could have led to a dilution of effect.  相似文献

Social media analysis provides an alternate approach to monitoring and understanding risk perceptions regarding COVID-19 over time. Our current understandings of risk perceptions regarding COVID-19 do not disentangle the three dimensions of risk perceptions (perceived susceptibility, perceived severity, and negative emotion) as the pandemic has evolved. Data are also limited regarding the impact of social determinants of health (SDOH) on COVID-19-related risk perceptions over time. To address these knowledge gaps, we extracted tweets regarding COVID-19-related risk perceptions and developed indicators for the three dimensions of risk perceptions based on over 502 million geotagged tweets posted by over 4.9 million Twitter users from January 2020 to December 2021 in the United States. We examined correlations between risk perception indicator scores and county-level SDOH. The three dimensions of risk perceptions demonstrate different trajectories. Perceived severity maintained a high level throughout the study period. Perceived susceptibility and negative emotion peaked on March 11, 2020 (COVID-19 declared global pandemic by WHO) and then declined and remained stable at lower levels until increasing once again with the Omicron period. Relative frequency of tweet posts on risk perceptions did not closely follow epidemic trends of COVID-19 (cases, deaths). Users from socioeconomically vulnerable counties showed lower attention to perceived severity and susceptibility of COVID-19 than those from wealthier counties. Examining trends in tweets regarding the multiple dimensions of risk perceptions throughout the COVID-19 pandemic can help policymakers frame in-time, tailored, and appropriate responses to prevent viral spread and encourage preventive behavior uptake in the United States.  相似文献

This study sought to examine the intermediary roles of different topics of conflict and negative emotions following conflicts in the associations between attachment insecurities and relationship satisfaction in a sample of 253 mixed-gender couples from the community. Results from path analyses based on the Actor–Partner Interdependence Model showed that attachment anxiety and attachment avoidance were associated with the perception, in both partners, of experiencing more conflicts in the relationship. In turn, the more participants perceived conflicts related to major issues and daily annoyances, the more they reported negative emotions following conflicts and lower relationship satisfaction. Participants’ report of conflicts related to major issues was also related to their partner's lower relationship satisfaction. Findings highlight the significance of accounting for the topics on which couples argue and of using an attachment-based framework to help couples deal with the negative emotions that they experience following conflicts.  相似文献

Based on qualitative research, this paper suggests that among some married/co‐habiting couples, where mothers are professionally employed and there are pre‐school children, fathers seek to enhance their paternal role. This contrasts with previous research, which indicates that married/co‐habiting men leave to mothers the responsibility for nurturing both maternal and paternal relationships with children. Using the notions of situational and debilitative power, it is shown how married/co‐habiting fathers developed strategies for augmenting paternal rights. While fathers' involvement with children was perceived as beneficial by some mothers, others regarded it as a threat to maternal status. The paper suggests that power relations between married/co‐habiting parents in the sample are similar to power struggles between couples who are separated or divorced. The possibility is raised that paternal strategies to diminish the maternal sphere of influence among both married/co‐habiting and divorced fathers may be symptomatic of wider male fears about the erosion of male hegemony. It is observed that the schemes employed by fathers in the sample to enhance the paternal role are similar to the approach advocated in policy statements of fathers' rights activists.  相似文献

Recent research suggests that the children of recent immigrants, the so-called second generation, no longer choose to emphasize one identity over the other but that their identities are more fluid and multifaceted. College campuses are often the arenas in which a new hybrid identity develops. This article addresses how South Asian American college students make sense of and control their various identities through the celebration of Diwali, an event sponsored each year by the Indian Students Association (ISA) on a college campus in the Dallas-Fort Worth metropolitan area. South Asian students use performative space to help them make sense of their backgrounds in ways that both differentiate them from and allow for association with the majority student population. They also use this space as a safe place for “coming out,” that is, for communicating their hybrid identity to their parents. This hybrid identity is expressed through a discourse of “brownness” that marks something distinctive and that reflects the process by which the children of immigrants choose among a range of identities to create integrated selves. The campus Diwali festival is the expression of those selves.  相似文献
