The overall suicide rate in the U.S. increased by 6% between 1981 and 1986 and declined by 18% between 1986 and 1999. Detailed descriptions of recent trends in suicide are lacking, especially with regard to the method of suicide. Information is needed on the major changes in rates of suicide in specific population groups in recent years (1999-2005). ⋯ The differential increases by age, race, gender, and method underscore a change in the epidemiology of suicide.Whites aged 40-64 years have recently emerged as a new high-risk group for suicide. Although firearms remain the most common method of suicide, the notable increases in suicide by poisoning in men and hanging/suffocation in women deserve prevention attention [corrected].

Helping young smokers to quit early in life substantially reduces the risk of later morbidity and mortality due to tobacco use. The RealU study demonstrated the efficacy of a smoking-cessation website for college students that incorporated both individually tailored feedback and peer e-mail support. The relationship between peer e-mail support and cessation outcomes among intervention participants is examined here. ⋯ Greater peer engagement via e-mail was associated with increased smoking abstinence and reduced frequency of smoking. These findings suggest that online peer support may be an important strategy when delivering Internet-assisted cessation programs to young adults.

Available studies of the built environment and the BMI of children and youth suggest a contemporaneous association with neighborhood greenness in neighborhoods with high population density. The current study tests whether greenness and residential density are independently associated with 2-year changes in the BMI of children and youth. ⋯ Greenness may present a target for environmental approaches to preventing child obesity. Children and youth living in greener neighborhoods had lower BMI z-scores at Time 2, presumably due to increased physical activity or time spent outdoors. Conceptualizations of walkability from adult studies, based solely on residential density, may not be relevant to children and youth in urban environments.

Prior research suggests that racial/ethnic minority smokers experience more difficulty with cessation than white smokers and access formal treatment less often. Minority smokers may respond differently to treatment interventions than white smokers. This prospective, observational cohort study compared long-term cessation outcomes among four racial/ethnic groups after an aided quit attempt using nicotine replacement therapy (NRT). ⋯ These findings indicate that racial/ethnic minorities are as likely to quit smoking at a level similar to whites when using cessation treatment that includes NRT. Given documented disparities in the use of evidence-based cessation treatments such as NRT, interventions are sorely needed to improve access and utilization of these treatments in racial/ethnic minority groups.

Randomized Controlled Trial
Computerized counseling for folate knowledge and use: a randomized controlled trial.
Periconception folate supplementation significantly reduces the risk of neural-tube defects, but few U.S. women start folate supplementation before pregnancy, and the amount of clinician time available to counsel patients about folate is limited. This study evaluated whether computer-assisted counseling and the provision of free folate tablets increases women's knowledge and use of folate supplements. ⋯ A one-time, brief, computerized counseling session about folate with the provision of free folate tablets increased the knowledge and use of folate supplements among women > or =6 months later.
