Objective
To examine the prevalence of sexting behaviors as well as their relation to dating, sex, and risky sexual behaviors using a large school-based sample of adolescents.

Design
Data are from time 2 of a 3-year longitudinal study. Participants self-reported their history of dating, sexual behaviors, and sexting (sent, asked, been asked, and/or bothered by being asked to send nude photographs of themselves).

Setting
Seven public high schools in southeast Texas.

Participants
A total of 948 public high school students (55.9% female) participated. The sample consisted of African American (26.6%), white (30.3%), Hispanic (31.7%), Asian (3.4%), and mixed/other (8.0%) teens.

Main Outcome Measure
Having ever engaged in sexting behaviors.

Results
Twenty-eight percent of the sample reported having sent a naked picture of themselves through text or e-mail (sext), and 31% reported having asked someone for a sext. More than half (57%) had been asked to send a sext, with most being bothered by having been asked. Adolescents who engaged in sexting behaviors were more likely to have begun dating and to have had sex than those who did not sext (all P < .001). For girls, sexting was also associated with risky sexual behaviors.

Conclusions
The results suggest that teen sexting is prevalent and potentially indicative of teens’ sexual behaviors. Teen-focused health care providers should consider screening for sexting behaviors to provide age-specific education about the potential consequences of sexting and as a mechanism for discussing sexual behaviors.

Antibacterial Drugs and the Risk of Community-Associated Methicillin-Resistant Staphylococcus aureus in Children

Objective
To investigate in children the association between antibacterial drugs and subsequent diagnosis of methicillin-resistant Staphylococcus aureus (MRSA) in the community.

Design
Population-based case-control study in children 1 to 19 years of age.

Setting
Primary care, General Practice Research Database, United Kingdom, 1994-2007.

Participants
Cases were children who had MRSA diagnosed as outpatients, and controls were individually matched on age and practice, with the matched case’s diagnosis date as the index date for both.

Main Exposures
Antibacterial agents prescribed 180 to 30 days prior to the index date, excluding prescriptions 30 days before the index date to prevent protopathic bias.

Outcome Measures
Rate ratios (RRs) estimated from the odds ratios of exposure in cases compared with controls using conditional logistic regression, adjusted for comorbid conditions, other prescription drug use, and hospitalization.

Results
The rate of MRSA was 4.5 per 100 000 per year. Of 297 cases and 9357 controls, 52.5% and 13.6%, respectively, received antibacterial drug prescriptions during the 150-day exposure window. The adjusted RR with any antibacterial drug was 3.5 (95% confidence interval [CI], 2.6-4.8). The RRs increased with the number of prescriptions (2.2 [95% CI, 1.5-3.2], 3.3 [95% CI, 1.9-5.6], 11.0 [95% CI, 5.6-21.6], and 18.2 [95% CI, 9.4-35.4] for 1, 2, 3, and 4 prescriptions, respectively). The RR was particularly elevated for quinolones at 14.8 (95% CI, 3.9-55.8), with wide variation among antibacterial classes.

Conclusion
While close to half of children were diagnosed as having MRSA in the community without prior antibacterial drugs, such agents are associated with a dose-dependent increased risk, concordant with findings in adults.

Objective  To determine the effectiveness of coach-led neuromuscular warm-up on reducing lower extremity (LE) injuries in female athletes in a mixed-ethnicity, predominantly low-income, urban population.

Design  Cluster randomized controlled trial.

Setting  Chicago public high schools.

Participants  Of 258 coaches invited to participate, 95 (36.8%) enrolled (1558 athletes). Ninety coaches and 1492 athletes completed the study.

Interventions  We randomized schools to intervention and control groups. We trained intervention coaches to implement a 20-minute neuromuscular warm-up. Control coaches used their usual warm-up.

Main Outcome Measures  Coach compliance was tracked by self-report and direct observation. Coaches reported weekly athlete exposures (AEs) and LE injuries causing a missed practice or game. Research assistants interviewed injured athletes. Injury rates were compared between the control and intervention groups using {chi}2 and Fisher exact tests. Significance was set at P < .05. Poisson regression analysis adjusted for clustering and covariates in an athlete subset reporting personal information (n = 855; 57.3%).

Results  There were 28 023 intervention AEs and 22 925 control AEs. Intervention coaches used prescribed warm-up in 1425 of 1773 practices (80.4%). Intervention athletes had lower rates per 1000 AEs of gradual-onset LE injuries (0.43 vs 1.22, P < .01), acute-onset noncontact LE injuries (0.71 vs 1.61, P < .01), noncontact ankle sprains (0.25 vs 0.74, P = .01), and LE injuries treated surgically (0 vs 0.17, P = .04). Regression analysis showed significant incidence rate ratios for acute-onset noncontact LE injuries (0.33; 95% CI, 0.17-0.61), noncontact ankle sprains (0.38; 95% CI, 0.15-0.98), noncontact knee sprains (0.30; 95% CI, 0.10-0.86), and noncontact anterior cruciate ligament injuries (0.20; 95% CI, 0.04-0.95).

Conclusion  Coach-led neuromuscular warm-up reduces noncontact LE injuries in female high school soccer and basketball athletes from a mixed-ethnicity, predominantly low-income, urban population.
