Among middle school students, sexual minorities and girls are more likely to be cyberbullied New research from the American Journal of Public Health finds that sexual minorities and girls are more likely to report being victims of cyberbullying, with the bullying taking place most often on Facebook.
Using data from a supplemental survey to the 2012 Centers for Disease Control and Prevention’s Youth Risk Behavior Survey in Los Angeles Unified School District, the study reviewed cyberbullying among more than 1,000 middle school students. Researchers captured information regarding cyberbullying victimization and perpetration, technology use and practices among the sample and additional demographic information.
Results from the study indicated that girls were more likely than boys to be victims of cyberbullying along with sexual minorities who were disproportionately more likely to be cyberbullied compared to heterosexual students. Students who texted at least 50 times a day were also more likely to report being victims of cyberbullying. Facebook was also found to be the most common platform for cyberbullying to take place.
“This study suggests that interventions should take into account social media platforms, gender and especially sexual identity,” the authors conclude.
“Research is needed to stay abreast of how cyberbullying evolves across the ever-changing landscape of social media platforms and new technology devices such as smartphones, tablets and even online gaming systems,” the researchers suggest.

Negative life events increase risk of adolescents beginning sexual intercourseThe occurrence of negative life events is associated with greater likelihood of adolescent initiation of sexual intercourse, according to new research from the American Journal of Public Health. The occurrence of just one negative life event increases an adolescent’s risk of initiating sexual intercourse.
The study reviewed results from the Youth Asset Study, a questionnaire capturing responses from more than 1,000 adolescent and parent pairs in Oklahoma City, Oklahoma. The questionnaire assessed initiation of sexual intercourse; family structure and income; age; and results from a negative life events scale. Initial data was collected between August 2003 and December 2004 with follow-ups taking place over the following four years.
Results from the study indicated that adolescents who reported one negative life event were at a 1.4 times greater risk of initiating sexual intercourse than their counterparts who experienced no negative life events. For participants who experienced two or more negative life events, the hazard of initiating sexual intercourse was 1.61 times greater.
“Even one negative life event puts youths at risk for initiation of sexual intercourse. Problems in school, breaking up or getting ‘dumped,’ and parent separation or divorce significantly increased the risk for initiation of sexual intercourse,” the authors explain.
“The costs of early initiation of sexual intercourse and risky sexual behaviors are high, both to individual adolescents and to society. Negative life events may make youths more vulnerable to engaging in health risk behaviors compared with those without recent negative life events,” they conclude.

Customer awareness and use of calorie information tripled following menu-labeling regulationAwareness and use of calorie information on menus tripled after implementation of restaurant menu-labeling regulation in King County, Washington, according to new research from the American Journal of Public Health.
Researchers used data from the Washington State Behavioral Risk Factor Surveillance System. They reviewed menu label habits from 2008 through 2010, accounting for time before and after implementation of King County’s menu-labeling regulation, which went into effect January 1, 2009. The survey included questions about participants’ awareness and use of calorie counts on menus when visiting establishments required to post this information. The study reviewed responses from more than 8,000 participants over the age of 18. From these data, 3,132 respondents who reported eating at a chain restaurant regulated by the menu-labeling policy comprised the study population.
Results from the study indicate an increase in awareness and use of calorie information on labeled menus between 2008 and 2010. The proportion of people who saw the calorie information increased from 18.6 percent in 2008 to 59.4 percent in 2010. The proportion of people who used the calorie information increased from 8.1 percent to 24.8 percent in this same time period. The study also found that men, non-whites including Hispanics and low-income populations were less likely to use and see the calorie information.
“Using estimates of King County’s 3-year (2008-2010) adult average population, we estimated that at least 600,000 more King County adults saw calorie information and more than 250,000 additional adults used this information after policy implementation,” the researchers wrote.
“The Food and Drug Administration, policymakers and public health practitioners should consider whether additional approaches are needed to not only improve menu-labeling awareness and use among all customers but also to help groups less likely to see and use menu labels better understand and translate calorie information into healthier food choices,” the authors recommend.
