Weight-Related Teasing in the School Environment: Associations with Psychosocial Health and Weight Control Practices Among Adolescent Boys and Girls

Weight-related teasing has been found to be associated with low self-esteem, depressive symptoms, body dissatisfaction, and weight control behaviors in adolescents. While research has typically examined weight-related teasing directed towards the individual, little is known about weight-related teasing at the school level. This study aimed to determine the association between the school-level prevalence of weight-related teasing and psychosocial factors, body dissatisfaction and weight control behaviors in adolescents. Adolescents (N = 2,793; 53.2 % female) attending 20 US public middle and high schools were surveyed as part of the Eating and Activity in Teens (EAT) 2010 study. Generalized estimating equations were used to estimate the association between school-level weight-related teasing and health variables, controlling for individual-level weight-related teasing, clustering of individuals within schools, and relevant covariates. A greater school-level prevalence of weight-related teasing was associated with lower self-esteem and greater body fat dissatisfaction in girls, and greater depressive symptoms in boys, over and above individual-level weight-related teasing. Dieting was associated with the school-level prevalence of weight-related teasing in analysis adjusted for covariates in girls, but not following adjustment for individual-level weight-related teasing. Unhealthy weight control behaviors, extreme weight control behaviors, and muscle-enhancing behaviors were not associated with the school-level prevalence of weight-related teasing in girls or boys. Findings from the current study, in conjunction with previous findings showing associations between weight-related teasing, psychological concerns, and weight control behaviors, highlight the importance of implementing strategies to decrease weight-related teasing in schools.     

Invited Commentary: Broadening the Evidence for Adolescent Sexual and Reproductive Health and Education in the United States

Scientific research has made major contributions to adolescent health by providing insights into factors that influence it and by defining ways to improve it. However, US adolescent sexual and reproductive health policies—particularly sexuality health education policies and programs—have not benefited from the full scope of scientific understanding. From 1998 to 2009, federal funding for sexuality education focused almost exclusively on ineffective and scientifically inaccurate abstinence-only-until-marriage (AOUM) programs. Since 2010, the largest source of federal funding for sexual health education has been the “tier 1” funding of the Office of Adolescent Health’s Teen Pregnancy Prevention Initiative. To be eligible for such funds, public and private entities must choose from a list of 35 programs that have been designated as “evidence-based” interventions (EBIs), determined based on their effectiveness at preventing teen pregnancies, reducing sexually transmitted infections, or reducing rates of sexual risk behaviors (i.e., sexual activity, contraceptive use, or number of partners). Although the transition from primarily AOUM to EBI is important progress, this definition of evidence is narrow and ignores factors known to play key roles in adolescent sexual and reproductive health. Important bodies of evidence are not treated as part of the essential evidence base, including research on lesbian, gay, bisexual, transgender, queer, and questioning (LGBTQ) youth; gender; and economic inequalities and health. These bodies of evidence underscore the need for sexual health education to approach adolescent sexuality holistically, to be inclusive of all youth, and to address and mitigate the impact of structural inequities. We provide recommendations to improve US sexual health education and to strengthen the translation of science into programs and policy.     

What is a land grab? Exploring green grabs,conservation, and private protected areas in southern Chile

Discussions of land grabs for various purposes, including environmental ends, have expanded in recent years, yet land grabbing remains inconsistently defined and poorly understood. Our ability to assess the extent to which land grabs are occurring, and to identify the mixture of factors driving land and resource acquisition, is limited. This paper assesses whether a land grab for conservation is happening in southern Chile, and identifies the various driving forces that combine to drive land acquisitions in the region, based on a detailed exploration of the recent massive growth in privately owned protected areas in the region. This paper finds that the various dominant definitions of land grabs each apply only partially to southern Chile, that land grabs for conservation need to be understood as the latest stage in a longer process by which the region's natural resources are incorporated into the Chilean and the global economy, and that green grabs interact in various ways with broader resource grabs, particularly for forestry and hydroelectricity. This case study demonstrates the limitations of some definitions of land grabs, particularly their focus on capitalist accumulation within land grabs, their international nature and their emphasis on legal processes.     

Anger Control and Acceptance of Violence as Mediators in the Relationship between Exposure to Interparental Conflict and Dating Violence Perpetration in Mexican Adolescents

Dating violence is a prevalent problem in high school students. Previous research has found that anger expression styles and acceptance of violence beliefs mediate the relationship between experiencing family violence and dating violence perpetration. Few studies have examined the intergenerational transmission of violence theory in predicting dating violence in Mexican teens. The purpose of this study is to examine the relationships among exposure to interparental violence, anger expression, acceptance of violence beliefs, and perpetration of teen dating violence in Mexican teens. Surveys were administered to 204 high school students (aged 15 to 17) from Monterrey, Mexico. Regression analyses revealed that anger control and acceptance of violence beliefs, mediated the relationship between interparental conflict and dating violence perpetration. These results support the use of family-based interventions that challenge acceptance of violence beliefs and teach anger control techniques in Mexican teens.
