This study examined the prevalence of selected clinical preventive health services, health status indicators, health risk behaviors, and health-promoting behaviors among adults aged 18 to 24 years in the general U.S. population. The study analyzed data from the 2003 Behavioral Risk Factor Surveillance System. Nearly 30% of young adults lacked health care coverage. When 21- to 24-year-olds were compared with 18- to 20-year-olds, a 32% increase was noted in current cigarette smoking, a 37% increase in current binge drinking, a 48% increase in current alcohol use, a 27% increase in overweight and obesity, and an 8% decrease in engaging in sufficient physical activity. Results from this study reveal several areas for concern regarding the health of young adults. Continuation of education beyond high school and being married are associated with some health benefits. Carefully crafted health promotion programs and appropriate policies need to be placed in locations that are accessed by this population. (Contains 4 tables.)

Background: School-based risk behavior surveys traditionally have been administered via paper-and-pencil. This study assessed the feasibility of conducting in-class online surveys in US high schools. Methods: A paper-and-pencil questionnaire assessing computer availability and perceptions of online surveys was mailed to a nationally representative sample of public and private high school principals in fall 2008. Completed surveys were returned by principals from 580 of 704 selected schools. Prevalence and 95% confidence intervals were computed. Results: Most high schools have at least 1 computer lab, most computers in computer labs are connected to the Internet, and just under half of schools with a stationary computer lab had a sufficient number of computers to accommodate an in-class online survey administration. The 2 most common problems associated with online surveys were logistics of providing enough computers for an entire class and rotating classes into computer labs. Nearly two thirds of principals preferred online to paper-and-pencil surveys when administered to 4 randomly selected classes that met at different times during the school day, but less than half reported this preference when administered to 4 randomly selected classes that met at the same time during the school day. Conclusion: Many schools do not have sufficient computer capacity to participate in a voluntary in-class online survey. An online survey could impose significant perceived and actual burden on schools and therefore could result in unacceptably low school participation rates. Online administration for in-class surveys of students in US high schools are not recommended. (Contains 4 tables.)

Background: The School Health Policies and Programs Study (SHPPS) 2006 is the largest, most comprehensive assessment of school health programs in the United States ever conducted. Methods: The Centers for Disease Control and Prevention conducts SHPPS every 6 years. In 2006, computer-assisted telephone interviews or self-administered mail questionnaires were completed by state education agency personnel in all 50 states plus the District of Columbia and among a nationally representative sample of districts (n = 538). Computer-assisted personal interviews were conducted with personnel in a nationally representative sample of elementary, middle, and high schools (n = 1103) and with a nationally representative sample of teachers of classes covering required health instruction in elementary schools and required health education courses in middle and high schools (n = 912) and teachers of required physical education classes and courses (n = 1194). Results: SHPPS 2006 describes key school health policies and programs across all 8 school health program components: health education, physical education and activity, health services, mental health and social services, nutrition services, healthy and safe school environment, faculty and staff health promotion, and family and community involvement. SHPPS 2006 also provides data to monitor 6 "Healthy People 2010" objectives. Conclusions: SHPPS 2006 is a new and important resource for school and public health practitioners, scientists, advocates, policymakers, and all those who care about the health and safety of youth and their ability to succeed academically and socially.

This study analyzed data from the School Health Policies and Programs Study (SHPPS) 2000 to examine the relationship between school health councils and selected school health policies and programs. SHPPS 2000 collected data from faculty and staff in a nationally representative sample of schools. About two-thirds (65.7%) of US schools have school health councils. Schools with councils were significantly more likely than schools without councils to report policies and programs related to health services, mental health and social services, faculty and staff health promotion, and family and community involvement. Schools with councils were as likely as schools without councils to report policies and programs related to health education, physical education, and food service. Although school health councils are associated with the presence of some key school health policies and programs, a council does not guarantee a school will have all important school health policies and programs in place.

Lesbian, gay, and bisexual (LGB) youth are at risk for many negative behaviors associated with teen dating violence victimization (TDVV). This study describes the prevalence of physical and sexual TDVV by sexual identity and quantifies the increased risk for TDVV among LGB youth compared with heterosexual youth. The participants for this study were students in Grades 9 to 12 participating in the 2015 national Youth Risk Behavior Survey (YRBS) who responded to questions ascertaining sexual identity and both physical and sexual TDVV. Data were analyzed by sexual identity, stratified by sex, and controlled for race/ethnicity and grade in school. Frequencies of physical and sexual TDVV and prevalence of TDVV from a combined TDVV measure were calculated. Associations between these behaviors and sexual identity were identified. Generally, LGB youth had greater prevalence and frequency of TDVV compared with heterosexual youth. Prevalence of TDVV within sexual identity subgroups further differed by sex. Students who were not sure of their sexual identity had the highest risk of most categories of TDVV when adjusting for sex, race/ethnicity, and grade in school. These results are the first to use a nationally representative sample to describe frequency of TDVV and to determine prevalence of a combined physical and sexual TDVV measure by sexual identity among youth. Schools, communities, and families can help prevent teen dating violence and ameliorate the potential impacts of these victimizations. [ABSTRACT FROM AUTHOR]

Early initiation of sexual activity is associated with having more sexual partners, not using condoms, sexually transmitted infection (STI), and pregnancy during adolescence (1,2). The majority of adolescents initiate sexual activity during high school, and the proportion of high school students who have ever had sexual intercourse increases by grade; black students are more likely to have ever had sexual intercourse than are white students (3). The proportion of high school students overall who had ever had sexual intercourse did not change significantly during 1995-2005 (53.1% to 46.8%) (Division of Adolescent and School Health, National Center for HIV/AIDS, Viral Hepatitis, STD, and TB Prevention, CDC, unpublished data). To assess whether changes have occurred in recent years in the proportion of high school students who have ever had sexual intercourse, CDC examined trends overall and by grade, race/ethnicity, and sex among U.S. high school students, using data from the 2005-2015 national Youth Risk Behavior Surveys (YRBSs) and data from 29 states* that conduct the YRBS and have weighted data. Nationwide, the proportion of high school students who had ever had sexual intercourse decreased significantly overall and among 9th and 10th grade students, non-Hispanic black (black) students in all grades, and Hispanic students in three grades. A similar pattern by grade was observed in nearly half the states (14), where the prevalence of ever having had sexual intercourse decreased only in 9th grade or only in 9th and 10th grades; nearly all other states saw decreases in some or all grades. The overall decrease in the prevalence of ever having had sexual intercourse during 2005-2015 is a positive change in sexual risk among adolescents (i.e., behaviors that place them at risk for human immunodeficiency virus, STI, or pregnancy) in the United States, an overall decrease that did not occur during the preceding 10 years. Further, decreases by grade and race/ethnicity represent positive changes among groups of students who have been determined in previous studies to be at higher risk for negative outcomes associated with early sexual initiation, such as greater numbers of partners, condom non-use, teen pregnancy, and STI (1-3). More work is needed to understand the reasons for these decreases and to ensure that they continue. [ABSTRACT FROM AUTHOR]

Studies have shown links between educational outcomes such as letter grades, test scores, or other measures of academic achievement, and health-related behaviors (1-4). However, as reported in a 2013 systematic review, many of these studies have used samples that are not nationally representative, and quite a few studies are now at least 2 decades old (1). To update the relevant data, CDC analyzed results from the 2015 national Youth Risk Behavior Survey (YRBS), a biennial, cross-sectional, school-based survey measuring health-related behaviors among U.S. students in grades 9-12. Analyses assessed relationships between academic achievement (i.e., self-reported letter grades in school) and 30 health-related behaviors (categorized as dietary behaviors, physical activity, sedentary behaviors, substance use, sexual risk behaviors, violence-related behaviors, and suicide-related behaviors) that contribute to leading causes of morbidity and mortality among adolescents in the United States (5). Logistic regression models controlling for sex, race/ethnicity, and grade in school found that students who earned mostly A's, mostly B's, or mostly C's had statistically significantly higher prevalence estimates for most protective health-related behaviors and significantly lower prevalence estimates for most health-related risk behaviors than did students with mostly D's/F's. These findings highlight the link between health-related behaviors and education outcomes, suggesting that education and public health professionals can find their respective education and health improvement goals to be mutually beneficial. Education and public health professionals might benefit from collaborating to achieve both improved education and health outcomes for youths. [ABSTRACT FROM AUTHOR]

Young persons aged 13-24 years accounted for an estimated 22% of all new diagnoses of human immunodeficiency virus (HIV) infection in the United States in 2014. Most new HIV diagnoses among youths occur among males who have sex with males (MSM). Among all MSM, young black MSM accounted for the largest number of new HIV diagnoses in 2014 (1). To determine whether the prevalence of HIV-related risk behaviors among black male high school students who had sexual contact with males differed from the prevalence among white and Hispanic male students who had sexual contact with males, potentially contributing to the racial/ethnic disparities in new HIV diagnoses, CDC analyzed data from Youth Risk Behavior Surveys conducted by 17 large urban school districts during 2009-2013. Although other studies have examined HIV-related risk behaviors among MSM (2,3), less is known about MSM aged <18 years. Black male students who had sexual contact with males had a lower or similar prevalence of most HIV-related risk behaviors than did white and Hispanic male students who had sexual contact with males. These findings highlight the need to increase access to effective HIV prevention strategies for all young MSM. [ABSTRACT FROM AUTHOR]

The article focuses on a study on the data for increase in availability of fruits, vegetables, and whole grains and decrease in sodium levels in the school meals across schools in the U.S. for the year 2000, 2006, and 2014. Topics include a chart depicting percentage of schools which engaged in specific school nutrition services practices regulated for the school meal programs, efforts to help schools meet the nutrition standards, and increase awareness about nutrition in school meals.

Objectives. To compare changes over time in prevalence of school victimization among lesbian, gay, and bisexual (LGB) students compared with heterosexual students. Methods. We analyzed data from 11 Youth Risk Behavior Surveys conducted among representative samples of students in grades 9 through 12 in Massachusetts during 1995 to 2015. Weused multivariable logistic regressionmodels to identify trends over time by sexual identity. Results. During 1995 to 2015, the prevalence of missing school decreased overall (from 5.6% to 4.8%) and among heterosexual (from 4.3% to 3.8%) and LGB (from 25.0%to 13.4%) students. The prevalence of having been threatened decreased overall (from 7.8% to 4.1%) and among heterosexual (from 6.5% to 3.5%) and LGB (from 32.9% to 6.7%) students. Conclusions. We identified evidence of a significant decrease in victimization among all students regardless of sexual identity and a steep decline among LGB students. Additional actions to improve school climate may help eliminate the disparities and decrease victimization for all youths. [ABSTRACT FROM AUTHOR]

Background: In 2009, 6.7% of the estimated 1.1 million persons living with human immunodeficiency virus (HIV) infection in the United States were youths (defined in this report as persons aged 13-24 years); more than half of youths with HIV (59.5%) were unaware of their infection. Methods: CDC used National HIV Surveillance System data to estimate, among youths, prevalence rates of diagnosed HIV infection in 2009 and the number of new infections (incidence) in 2010. To assess the prevalence of risk factors and HIV testing among youths, CDC used the 2009 and 2011 Youth Risk Behavior Surveillance System for 9th-12th grade students and the 2010 National Health Interview Survey (NHIS) for persons 18-24 years. Results: Prevalence of diagnosed HIV was 69.5 per 100,000 youths at the end of 2009. Youths accounted for 12,200 (25.7%) new HIV infections in 2010. Of these, 7,000 (57.4%) were among blacks/African Americans, 2,390 (19.6%) among Hispanics/Latinos, and 2,380 (19.5%) among whites; 8,800 (72.1%) were attributed to male-to-male sexual contact. The percentage of youths tested for HIV overall was 12.9% among high school students and 34.5% among those aged 18-24 years; it was lower among males than females, and lower among whites and Hispanics/Latinos than blacks/African Americans. Conclusions: A disproportionate number of new HIV infections occurs among youths, especially blacks/African Americans, Hispanics/Latinos, and men who have sex with men (MSM). The percentage of youths tested for HIV, however, was low, particularly among males. Implications for Public Health: More effort is needed to provide effective school- and community-based interventions to ensure all youths, particularly MSM, have the knowledge, skills, resources, and support necessary to avoid HIV infection. Health-care providers and public health agencies should ensure that youths are tested for HIV and have access to sexual health services, and that HIV-positive youths receive ongoing health-care and prevention services.

The article discusses the trends in the behavior of high school students in the U.S. which contribute to the prevalence of human immunodeficiency virus (HIV), based on data released by the Youth Risk Behavior Survey. It states that contributing factors include engaging in sexual intercourse without using condoms, having multiple sex partners, and using injectable drugs. A table showing the percentage of students reporting HIV-related risk behaviors is also presented.

The article summarizes the results of analyses of 2008 and 2010 School Health Profiles data for public secondary schools in 45 U.S. states. It was found that in 2010, the percentage of secondary schools teaching 11 topics on HIV, other sexually transmitted diseases (STDs) and pregnancy prevention in a required course in grades 6, 7, or 8 was lower in 11 states and significantly higher in none, compared with 2008. The importance of HIV, other STD, and pregnancy prevention education is stressed.

Objectives. We provided national prevalence estimates for selected health-risk behaviors for Asian American and Pacific Islander high school students separately, and compared those prevalence estimates with those of white, black, and Hispanic students. Methods. We analyzed data from the Youth Risk Behavior Surveillance System. To generate a sufficient sample of Asian American and Pacific Islander students, we combined data from four nationally representative surveys of U.S. high school students conducted in 2001, 2003, 2005, and 2007 (total n=56,773). Results. Asian American students were significantly less likely than Pacific Islander, white, black, or Hispanic students to have drunk alcohol or used marijuana. Asian American students also were the least likely to have carried a weapon, to have been in a physical fight, to have ever had sexual intercourse, or to be currently sexually active. Once sexually active, Asian American students were as likely as most other racial/ethnic groups to have used alcohol or drugs at last sexual intercourse or to have used a condom at last sexual intercourse. Pacific Islander students were significantly more likely than Asian American, white, black, or Hispanic students to have seriously considered or attempted suicide. Conclusions. The prevalence estimates of health-risk behaviors exhibited by Asian American students and Pacific Islander students are very different and should be reported separately whenever feasible. To address the different health-risk behaviors exhibited by Asian American and Pacific Islander students, prevention programs should use culturally sensitive strategies and materials.

Problem: Priority health-risk behaviors, which are behaviors that contribute to the leading causes of morbidity and mortality among youth and adults in Pacific Island territories, often are established during adolescence and extend into adulthood. Reporting Period Covered: January-June 2007. Description of the System: The Youth Risk Behavior Surveillance System (YRBSS) monitors six categories of priority health-risk behaviors among youth and young adults, including behaviors that contribute to unintentional injuries and violence; tobacco use; alcohol and other drug use; sexual behaviors that contribute to unintended pregnancy and sexually transmitted diseases, including human immunodeficiency virus infection; unhealthy dietary behaviors; and physical inactivity. In addition, the YRBSS monitors the prevalence of obesity and asthma. YRBSS includes a national school-based survey conducted by CDC and state, territorial, tribal, and local school-based surveys conducted by state, territorial, tribal, and local education and health agencies. This report summarizes results from surveys of students in grades 9-12 conducted in five territories (American Samoa, Commonwealth of the Northern Mariana Islands, Guam, Republic of the Marshall Islands, and Republic of Palau) during January-June 2007. Results: Across the five Pacific Island territories, the leading causes of mortality among all ages include unintentional injuries, including motor-vehicle crashes; cancer; cardiovascular diseases; stroke; and diabetes. Results from the Youth Risk Behavior Survey (YRBS) indicated that high school students in the Pacific Island territories engaged in behaviors that increased their risk for mortality or morbidity from these causes. Across the five territories during 2007, the percentage of high school students who had rarely or never worn a seat belt when riding in a car driven by someone else ranged from 11.8% to 83.2% (median: 30.9%). During the 30 days before the survey, the percentage who had ridden in a car or other vehicle driven by someone who had been drinking alcohol ranged from 34.8% to 49.8% (median: 42.8%), the percentage who had driven a car or other vehicle when they had been drinking alcohol ranged from 7.8% to 16.1% (median: 11.9%), and the percentage who had carried a weapon ranged from 16.9% to 32.0% (median: 19.6%). The percentage of students who had smoked cigarettes during the 30 days before the survey ranged from 23.1% to 37.6% (median: 31.1%), the percentage who had not eaten fruits and vegetables five or more times per day during the 7 days before the survey ranged from 72.8% to 83.6% (median: 79.5%), and the percentage who had not met recommended levels of physical activity ranged from 64.0% to 77.2% (median: 68.9%). Interpretation: The prevalence of many health-risk behaviors varies across the five Pacific Island territories, and many high school students engage in behaviors that place them at risk for the leading causes of mortality and morbidity. Public Health Action: YRBSS data will be used in the territories for decision making and program planning, resulting in more effective school health and youth health programs. More evidence-based interventions and programs are needed to reduce risk behaviors and improve health outcomes among youth. [ABSTRACT FROM AUTHOR]

Problem: Priority health-risk behaviors, including tobacco use, unhealthy dietary behaviors, and physical inactivity often are established during childhood and adolescence, extend into adulthood, are interrelated, and are preventable. These behaviors contribute to chronic disease and other health conditions, including asthma. Reporting Period Covered: January-May 2007. Description of System: The Youth Risk Behavior Surveillance System (YRBSS) monitors priority health-risk behaviors and the prevalence of obesity and asthma among youth and young adults. YRBSS includes a national school-based survey conducted by CDC and state and local school-based surveys conducted by state and local education and health agencies. In 2007, as a component of YRBSS, communities participating in the Steps Cooperative Agreement Program (Steps Program) also conducted school-based surveys of students in grades 9-12 in their program intervention areas. These communities used a standard questionnaire that measured tobacco use, dietary behaviors, and physical activity and monitored the prevalence of obesity and asthma. This report summarizes results from surveys of students in 26 Steps communities that conducted surveys in 2007. Results: Results from the 26 Steps communities indicated that a substantial proportion of adolescents engaged in health-risk behaviors that increased their likelihood of becoming obese. During 2007, across surveys, the percentage of high school students who had ever smoked at least one cigarette every day for 30 days ranged from 3.7% to 20.1% (median: 9.0%), the percentage who had eaten fruits and vegetables five or more times per day during the 7 days before the survey ranged from 13.9% to 23.9% (median: 17.9%), and the percentage who met recommended levels of physical activity ranged from 27.7% to 55.5% (median: 40.1%). Across surveys, the percentage of students who were obese ranged from 4.6% to 20.2% (median: 13.6%), and the percentage of students who had ever been told by a doctor or nurse that they had asthma ranged from 16.8% to 28.5% (median: 21.6%). Interpretation: Although the prevalence of many health-risk behaviors and health conditions related to obesity and asthma varies across Steps communities, a substantial proportion of high school students engage in behaviors that place them at risk for chronic disease. Public Health Action: Steps Program staff at the national, tribal, state, and local levels will use YRBSS data for decision making, program planning, and enhancing technical assistance to reduce tobacco use and exposure and to increase healthy eating and physical activity. These data will be used to help focus existing programs on activities that have shown the greatest promise of results, as well as identify populations of greatest need and opportunities for strategic collaboration to identify and disseminate lessons learned.

Problem: Priority health-risk behaviors, which are behaviors that contribute to the leading causes of morbidity and mortality among youth and adults, often are established during childhood and adolescence, extend into adulthood, are interrelated, and are preventable. Reporting Period Covered: January-December 2007. Description of the System: The Youth Risk Behavior Surveillance System (YRBSS) monitors six categories of priority health-risk behaviors among youth and young adults, including behaviors that contribute to unintentional injuries and violence; tobacco use; alcohol and other drug use; sexual behaviors that contribute to unintended pregnancy and sexually transmitted diseases (STDs), including human immunodeficiency virus (HIV) infection; unhealthy dietary behaviors; and physical inactivity. In addition, YRBSS monitors the prevalence of obesity and asthma. YRBSS includes a national school-based survey conducted by CDC and state and local school-based surveys conducted by state and local education and health agencies. This report summarizes results from the national survey, 39 state surveys, and 22 local surveys conducted among students in grades 9-12 during 2007. Results: In the United States, 72% of all deaths among persons aged 10-24 years result from four causes: motor-vehicle crashes, other unintentional injuries, homicide, and suicide. Results from the 2007 national Youth Risk Behavior Survey (YRBS) indicated that many high school students engaged in behaviors that increased their likelihood of death from these four causes. Among high school students nationwide during 2007, 11.1% had never or rarely worn a seat belt when riding in a car driven by someone else. During the 30 days before the survey, 29.1% of high school students had ridden in a car or other vehicle driven by someone who had been drinking alcohol, 18.0% had carried a weapon, and 5.5% had not gone to school because they felt they would be unsafe at school or on their way to or from school. During the 12 months before the survey, 6.9% of high school students had attempted suicide. In addition, 75.0% of high school students had ever drunk alcohol, and 4.4% had ever used methamphetamines. Substantial morbidity and social problems among youth also result from unintended pregnancies and STDs, including HIV infection. Results from the 2007 survey indicated that 47.8% of students had ever had sexual intercourse, 35.0% of high school students were currently sexually active, and 38.5% of currently sexually active high school students had not used a condom during last sexual intercourse. Among U.S. adults aged >25 years, 59% of all deaths result from two causes: cardiovascular disease and cancer. Results from the 2007 national YRBS indicated that risk behaviors associated with these two causes of death were present during adolescence. Among high school students nationwide during 2007, 20.0% had smoked cigarettes during the 30 days before the survey, 35.4% had watched television 3 or more hours per day on an average school day, and 13.0% were obese. During the 7 days before the survey, 78.6% of high school students had not eaten fruits and vegetables five or more times per day, 33.8% had drunk soda or pop at least one time per day, and 65.3% had not met recommended levels of physical activity. Interpretation: Since 1991, the prevalence of many health-risk behaviors among high school students nationwide has decreased. However, many high school students continue to engage in behaviors that place them at risk for the leading causes of mortality and morbidity. The prevalence of most risk behaviors does not vary substan- tially among cities and states.… [ABSTRACT FROM AUTHOR]

In the United States, more than 53 million young people attend nearly 120,000 schools, usually for 13 of their most formative years. Modern school health programs--if appropriately designed and implemented--could become one of the most efficient means the nation might employ to reduce the establishment of four main chronic disease risks: tobacco use, unhealthy eating patterns, inadequate physical activity, and obesity. The U.S. Centers for Disease Control and Prevention and its partners have developed four integrated strategies to help the nation's schools reduce these risks. Participating national, state, and local agencies (1) monitor critical health risks among students, and monitor school policies and programs to reduce those risks; (2) synthesize and apply research to identify, and to provide information about, effective school policies and programs; (3) enable state, large city, and national education and health agencies to jointly help local schools implement effective policies and programs; and (4) evaluate implemented policies and programs to iteratively assess and improve their effectiveness.

ABSTRACT: Television (TV) viewing has been associated with overweight, decreased physical activity, and unhealthy dietary, behavior among children and adolescents, and may represent a modifiable cause of childhood obesity. This study examined race, ethnic and gender-specific differences in these associations among high school students in the United States. The study analyzed data from the 1999 national Youth Risk Behavior Survey, a representative sample (N = 15,349) of US high school students. Logistic regression tested for significant associations. TV viewing on an average school day exceeded 2 hours/day among 43% of students: it was greater among Black (74%) and Hispanic (52%) than White (34%) students. Overall, 11% of students were overweight, 31% of students were sedentary, (ie, did not participate in moderate or vigorous physical activity at recommended levels), and 76% ate less than five servings/day of fruits and vegetables. Watching TV more than 2 hours/day was associated with being overweight, being sedentary, and eating insufficient fruits and vegetables among White females, and with being overweight among Hispanic females. No significant associations were found among Black females. TV viewing was associated with being overweight and eating insufficient fruits and vegetables among White males. No significant associations were found among Hispanic males. Among Black males, TV viewing was associated with greater participation in physical activity. These findings suggest the presence of cultural factors to consider when developing interventions to promote physical activity, healthy eating, and healthy weight through reduced TV viewing among adolescents.

ABSTRACT: Priority health-risk behaviors, which contribute to the leading causes of mortality and morbidity among youth and adults, often are established during youth, extend into adulthood, are interrelated, and are preventable. This report covers data during February-December 2001. The Youth Risk Behavior Surveillance System (YRBSS) monitors six categories of priority healthrisk behaviors among youth and young adults; these behaviors contribute to unintentional injuries and violence; tobacco use; alcohol and other drug use; sexual behaviors that contribute to unintended pregnancy and sexually transmitted diseases (STDs), including human immunodeficiency virus (HIV) infection; unhealthy dietary behaviors; and physical inactivity. The YRBSS includes a national school-based survey conducted by CDC as well as state, territorial, and local school-based surveys conducted by education and health agencies. This report summarizes results from the national survey, 34 state surveys, and 18 local surveys conducted among students in grades 9-12 during February-December 2001. In the United States, approximately three-fourths of all deaths among persons aged 10-24 years result from only four causes: motorvehicle crashes, other unintentional injuries, homicide, and suicide. Results from the 2001 national Youth Risk Behavior Survey demonstrated that numerous high school students engage in behaviors that increase their likelihood of death from these four causes: 14.1% had rarely or never worn a seat belt during the 30 days preceding the survey; 30.7% had ridden with a driver who had been drinking alcohol; 17.4% had carried a weapon during the 30 days preceding the survey; 47.1% had drunk alcohol during the 30 days preceding the survey; 23.9% had used marijuana during the 30 days preceding the survey; and 8.8% had attempted suicide during the 12 months preceding the survey. Substantial morbidity and social problems among young persons also result from unintended pregnancies... [ABSTRACT FROM AUTHOR]

ABSTRACT: To examine recent trends in physical education (PE) enrollment, daily attendance in PE, and being physically active in PE among high school students in the United States, this study analyzed data from the 1991, 1993, 1995, and 1997 national school-based Youth Risk Behavior Surveys (n = 55,734). Logistic regression analyses were conducted to test for significant linear time trends among the total student population and demographic subgroups (gender, race/ethnicity, and grade). Although PE enrollment in the total student population did not change from 1991 (48.9%) to 1997 (48.8%), the prevalence of students who attended PE daily, and the prevalence of students who were physically active >20 minutes in an average PE class both decreased significantly among nearly all demographic subgroups. The prevalence of students who were physically active >20 minutes in daily PE classes decreased from 34.2% in 1991 to 21.7% in 1997 (p < 0.001). To reverse current trends, high schools should implement daily PE classes that emphasize participation in lifelong health-related physical activity for all students.

ABSTRACT: Priority health-risk behaviors, which contribute to the leading causes of mortality and morbidity among youth and adults, often are established during youth, extend into adulthood, are interrelated, and are preventable. The Youth Risk Behavior Surveillance System (YRBSS) monitors six categories of priority health-risk behaviors among youth and young adults -- behaviors that contribute to unintentional and intentional injuries; tobacco use; alcohol and other drug use; sexual behaviors that contribute to unintended pregnancy and sexually transmitted diseases (STDs) (including human immunodeficiency virus [HIV] infection); unhealthy dietary behaviors; and physical inactivity. The YRBSS includes a national school-based survey conducted by CDC as well as state, territorial, and local school-based surveys conducted by education and health agencies. This report summarizes results from the national survey, 33 state surveys, and 16 local surveys conducted among high school students during February through May 1999. In the United States, approximately three fourths of all deaths among persons aged 10-24 years result from only four causes: motor-vehicle crashes, other unintentional injuries, homicide, and suicide. Results from the 1999 national Youth Risk Behavior Survey demonstrate that numerous high school students engage in behaviors that increase their likelihood of death from these four causes -16.4% had rarely or never worn a seat belt; during the 30 days preceding the survey, 33.1% had ridden with a driver who had been drinking alcohol; 17.3% had carried a weapon during the 30 days preceding the survey; 50.0% had drunk alcohol during the 30 days preceding the survey; 26.7% had used marijuana during the 30 days preceding the survey; and 7.8% had attempted suicide during the 12 months preceding the survey. Substantial morbidity and social problems among young persons also result from unintended pregnancies and STDs, including HIV infection. In 1999, nationwi... [ABSTRACT FROM AUTHOR]

The article examines trends in rates of self-reported HIV-related instruction and behaviors among high school students in the United States. Data used in the article were obtained from self-administered questionnaires completed anonymously in the classroom by three independent samples of high school students surveyed in 1989, 1990, and 1991. The authors used T-tests to assess significant bivariate associations. To determine significant changes over time, they used multiple logistic regression to calculate the effect of time on each HIV-related measure. Sex, race/ethnicity, and age group were included as control variables in each model. Because the surveys were conducted during the same months of each year, the authors made no additional time adjustments. After controlling for age group, race/ethnicity, and sex, they found that the proportion of students who had received HIV instruction in school increased significantly, from 1989 to 1991. School-based HIV instruction, which is reaching greater numbers of U.S. students, might be contributing to the decline in reported risk behavior.

Objectives. Few data have been available among adolescents to determine behavioral changes that may prevent human immunodeficiency virus (HIV) infection. This analysis examines changes in the prevalence of self-reported HIV-related information sources, instruction, knowledge, and behaviors among high school students in the United States. Methods. Two independent, multistage national probability samples of students in grades 9 through 12 were surveyed in 1989 (n = 8098) and 1990 (n = 11 631) with self-administered, anonymous questionnaires that included similar items. Results. Compared with students surveyed in 1989, a significantly greater proportion of students surveyed in 1990 had received HIV instruction in school. Significant decreases were found in the proportion of White and female students who reported having had sexual intercourse, in the proportion of White students reporting two or more lifetime sex partners, and in the proportion of 15- and 16-year-olds, White students, and female students who reported having had four or more lifetime sex partners. For both years, students who had a greater level of HIV knowledge were less likely to have had multiple lifetime sex partners or to have injected illicit drugs. Conclusions. The findings suggest that school-based HIV education and knowledge may be contributing factors in reducing certain risk behaviors that can lead to HIV transmission among secondary school youth.

Background. The prevalence of HIV-related behaviors and determinants of these behaviors among adolescents in the United States have not been well studied. Methods. To determine the prevalence of HIV-related drug behaviors and to assess the effects of HIV-related school-based instruction and HIV knowledge on these behaviors, data were analyzed from a 39-item, self-administered questionnaire completed by a probability sample of all students in grades 9 through 12 in the United States. Results. Usable responses were obtained from 8098 students. Of these, 2.7% (95% confidence interval [CI] = 2.3-3.2) and 1.7% (95% CI = 1.3-2.1) reported injecting illicit drugs ever and during the past year, respectively. Corresponding prevalences of needle sharing were 0.8% (95% CI = 0.5-1.1) and 0.5% (95% CI = 0.3-0.7). Regression analysis revealed that students with higher knowledge scores were less likely and males more likely to have ever injected drugs. HIV knowledge was similarly associated with other outcome measures of drug-injection behavior. Although HIV instruction did not directly influence drug-injection behavior independently of demographic characteristics, it was positively associated with HIV knowledge. Conclusions. While these results do not establish a causal relationship, they suggest that HIV knowledge and school-based instruction may play a role in maintaining low levels of drug-injection behavior among high school students.

Background: Recent declines in current cigarette smoking among youth are encouraging, but less is known about the trends in the number of cigarettes smoked per day among youth. Purpose: This study examined trends in the number of cigarettes smoked per day among U.S. high school students during 1991–2009. Methods: Nationally representative data from the 1991–2009 national Youth Risk Behavior Surveys (YRBS) were analyzed in 2010. The YRBS is a biennial, school-based survey representative of 9th- through 12th-grade students in the U.S. Each survey year, students completed anonymous, self-administered questionnaires that included identically worded questions about cigarette use. The number of cigarettes smoked per day on smoking days was categorized as light smoking (<1–5 cigarettes per day); moderate smoking (6–10 cigarettes per day); and heavy smoking (≥11 cigarettes per day). Sample sizes ranged from 10,904 to 16,410. Overall response rates ranged from 60% to 71%. Results: During 1991–2009, among current cigarette users overall, light smoking increased from 67.2% to 79.4% and heavy smoking decreased from 18.0% to 7.8%. These trends were found among female and male students overall and white students. Among Hispanic students, light smoking remained stable, but heavy smoking significantly increased from 3.1% in 1991 to 6.4% in 2009. The prevalence of light, moderate, and heavy smoking did not change during 1991–2009 among black students. Conclusions: The finding that during 1991–2009 light smoking increased and heavy smoking decreased among current cigarette users is encouraging; however, even light smoking is detrimental to health and efforts to reduce all cigarette use should continue.

The article reports on the extent of beverage consumption among high school students in the U.S. in 2010, based on data from the 2010 National Youth Physical Activity and Nutrition Study analyzed by the U.S. Centers for Disease Control and Prevention (CDC). According to results, 24.3 percent of students drank a serving of regular soda or pop, while 16.1 percent drank a serving of sports drink, and 16.9 percent drank a serving of another sugar-sweetened beverage (SSB) one or more times per day during the same period. A higher number of male students appeared to drink SSBs compared to females, and African American students were more likely to consume SSBs than white and Hispanic students. INSET: What is already known on this topic?.

The article focuses on the Youth Risk Behavior Surveillance System (YRBSS) developed by the U.S. Centers for Disease Control and Prevention (CDC) to focus the nation on behaviors among youth including alcohol and other drug use. The YRBSS was developed in 1989 and was first implemented in 1990. The YRBSS consisted of local and National Youth Risk Behavior Surveys which were school-based, focused on 9th-12th grade students, and used a self-administered questionnaire. The Youth Risk Behavior Surveys are providing data to national, state, and local public health and education officials to help describe risk behaviors; create awareness among policy makers and the general public about the prevalence of risk behaviors; and set and monitor program goals at the federal, state, and local levels.
