Prevalence and risk and protective factors related to disordered eating behaviors among adolescents: relationship to gender and ethnicity

PURPOSE To examine the current prevalence of disordered eating behaviors in a large sample of adolescents, by gender and ethnicity, and to identify gender and ethnic-specific risk and protective factors. METHODS The study population included 81,247 9th- and 12th-graders who completed the 1998 Minnesota Student Survey, a self-report, school-based survey which included questions about disordered eating behaviors and a variety of psychosocial characteristics. RESULTS Fifty-six percent of 9th-grade females and 28% of 9th-grade males report disordered eating behaviors (i.e. one or more of the following to lose or control weight: fasting or skipping meals, diet pills, vomiting, laxatives or smoking cigarettes; and binge-eating), with slightly higher rates among 12th-grade females and males, 57% and 31%, respectively. Among both genders, Hispanic and American Indian youth reported the highest prevalence of disordered eating. Risk factors for disordered eating among both males and females included cigarette smoking, appearance concerns, and alcohol use. Protective factors for both males and females were positive self-esteem, emotional well-being, school achievement, and family connectedness. While risk and protective factors were similar across gender, they differed across ethnicity particularly among females. CONCLUSIONS Health professionals working with youth need to be aware of the high prevalence of these subclinical disordered eating behaviors, ask appropriate screening questions, and provide resources and referral, if necessary, for youth reporting these behaviors. Knowledge of risk and protective factors can serve to guide intervention and prevention efforts, particularly as they apply across ethnicity.

Influences on adolescents’ decision to postpone onset of sexual intercourse: a survival analysis of virginity among youths aged 13 to 18 years

BACKGROUND Previous research has focused on risk factors associated with early onset of sexual intercourse among adolescents. This study hypothesizes that protective factors identified for other health compromising behaviors are also protective against early onset of sexual intercourse. The study sample included 26,023 students in grades 7-12 (87.5% white, 52.5% male) who did not report a history of sexual abuse in a statewide survey of adolescent health in 1988. METHODS Bivariate analyses were stratified into early (13-14 years), middle (15-16 years) and late (17-18 years) adolescence and by gender. Cox proportional hazards survival analysis, stratified by gender, was used to determine risk and protective factors associated with delayed onset of sexual intercourse. RESULTS Variables showing a significant bivariate association with lower levels of sexual activity across all age groups and genders were: dual-parent families, higher socioeconomic status (SES), better school performance, greater religiosity, absence of suicidal thoughts, feeling adults or parents cared, and high parental expectations. High levels of body pride were associated with higher levels of sexual activity for all age and gender groups. In the multivariate survival analyses, variables significantly associated with delayed onset of sexual activity for both males and females included: dual-parent families, higher SES, residing in rural areas, higher school performance, concerns about the community, and higher religiosity. High parental expectations were a significant protective factor for males but not for females. CONCLUSION While many protective factors are not subject to intervention, the present analyses indicate that teen pregnancy prevention may be enhanced by addressing family and educational factors.

Addressing Transition to Adult Health Care for Adolescents With Special Health Care Needs

Objective. To determine the factors associated with addressing the transition from pediatric to adult-oriented health care among US adolescents with special health care needs. Methods. Data for 4332 adolescents, 14 to 17 years of age, from the 2000–2001 National Survey of Children With Special Health Care Needs were used. The adequacy of transition services was determined by parent self-report. Explanatory variables, including parental education, family poverty status, race/ethnicity, measures of the severity and complexity of conditions, health insurance status, having a personal doctor, and the quality of the parents relationship with the adolescents doctor, were entered into a regression model. Results. Overall, 50.2% of parents reported that they had discussed transition issues with their adolescents doctor and 16.4% had discussed and developed a plan for addressing those needs. In a multivariate regression analysis, correlates of the adequacy of transition services included older age, female gender, complexity of health care needs, and higher quality of the parent-doctor relationship. Conclusions. Among adolescents with special health care needs, those who were older and those with more complicated needs were more likely to have addressed the transition from a pediatric to adult-oriented system of care. Furthermore, this analysis demonstrated a strong association between a high-quality parent-provider relationship and the extent to which transition issues were addressed. The importance of transition services for adolescents with less complex needs and the overall impact of health care transition services were not assessed in this study and remain important questions for future investigations.

Health risk behaviors and associated risk and protective factors among Brazilian Adolescents in Santos, Brazil

OBJECTIVE To describe the prevalence of health risk behaviors and identify risk and protective factors that are associated with several health risk behaviors (cigarette smoking, drug use, onset of sexual intercourse before age 15, pregnancy, gun-carrying, suicidal ideation, and suicide attempts) among adolescents in Brazil, as well as to explore gender differences. METHODS We estimated prevalence rates, evaluated bivariate associations, and explored multivariate analyses using logistic regression on data from a 1997 survey of adolescent health among 2059 eighth- and 10(th)-grade students in Santos, Brazil. RESULTS Youth in Santos, Brazil report high rates of gun-carrying, suicidal thoughts and attempts, sexual intercourse, and pregnancy. Factors associated with diminished involvement for nearly all health risk behaviors, for both boys and girls, included having good family relationships, and feeling liked by friends and teachers. Factors associated with increases in nearly all health risk behaviors were: gun-carrying and gun availability in the home, drug use, and sexual abuse. CONCLUSIONS Factors that are associated with a wide range of health risk behaviors among adolescents in Brazil appear to parallel those found in industrialized countries: access to guns, substance use, and sexual abuse. Likewise, connectedness to family, school, and peers is consistently the protective factor associated with diminished risky behaviors.

Transition to Adulthood: Delays and Unmet Needs among Adolescents and Young Adults with Asthma

OBJECTIVE To examine the effect of the transition to adulthood on financial and non-financial barriers to care in youth with asthma. STUDY DESIGN With National Health Interview Survey data from 2000 to 2005, we examined delays and unmet needs because of financial and non-financial barriers, evaluating the effect of adolescent (age, 12-17 years; n = 1539) versus young adult age (age, 18-24 years; N = 833), controlling for insurance, usual source of care, and sociodemographic characteristics. We also simulated the effects of providing public insurance to uninsured patients and a usual source of care to patients without one. RESULTS More young adults than adolescents encountered financial barriers resulting in delays (18.6% versus 8%, P < .05) and unmet needs (26.6% versus 11.4%, P < .05), although delays caused by non-financial barriers were similar (17.3% versus 14.9%, P = not significant). In logistic models young adults were more likely than adolescents to report delays (odds ratio [OR], 1.45; 95% CI, 1.02-2.08) and unmet needs (OR, 1.8; 95% CI, 1.29-2.52) caused by financial barriers. CONCLUSIONS Delays and unmet needs for care caused by financial reasons are significantly higher for young adults than they are for adolescents with asthma.

Adolescents with learning disabilities: risk and protective factors associated with emotional well-being: findings from the National Longitudinal Study of Adolescent Health

PURPOSE To identify differences in emotional well-being among adolescents with and without learning disabilities and to identify risk and protective factors associated with emotional distress. METHODS Cross-sectional analysis of adolescent in-home interview data of the National Longitudinal Study of Adolescent Health. A total of 20,780 adolescents were included in this study of whom 1,301 were identified as having a learning disability. Initially, emotional distress, suicidal behaviors, and violence involvement were compared among those adolescents with and without learning disabilities using Students t-test for the continuous or semicontinuous variables and Chi-square for the dichotomous variables. Subsequently, logistic regression analyses were conducted to identify which variables were most strongly associated with risk and protective factors for emotional distress. RESULTS Adolescents with learning disabilities had twice the risk of emotional distress, and females were at twice the risk of attempting suicide and for violence involvement than their peers. While educational achievement is below that of peers, connectedness to school is comparable. So, too, is connectedness to parents. Connectedness to parents and school was identified as most strongly associated with diminished emotional distress, suicide attempts, and violence involvement among adolescents with learning disabilities. CONCLUSIONS Given the increased association with emotional distress, suicidal attempts, and violence involvement, clinicians need to assess social and emotional as well as educational and physical functioning of these young people. We also need to be aware of the role protective factors play in the lives of young people with learning disabilities.

Medical Homes for Children With Autism: A Physician Survey

BACKGROUND. Primary care physicians can enhance the health and quality of life of children with autism by providing high-quality and comprehensive primary care. OBJECTIVE. To explore physicians’ perspectives on primary care for children with autism. METHODS. National mail and e-mail surveys were sent to a random sample of 2325 general pediatricians and 775 family physicians from April 2007 to October 2007. RESULTS. The response rate was 19%. Physicians reported significantly lower overall self-perceived competency, a greater need for primary care improvement, and a greater desire for education for children with autism compared with both children with other neurodevelopmental conditions and those with chronic/complex medical conditions. The following barriers to providing primary care were endorsed as greater for children with autism: lack of care coordination, reimbursement and physician education, family skeptical of traditional medicine and vaccines, and patients using complementary alternative medicine. Adjusting for key demographic variables, predictors of both higher perceived autism competency and encouraging an empirically supported therapy, applied behavior analysis, included having a greater number of autism patient visits, having a friend or relative with autism, and previous training about autism. CONCLUSIONS. Primary care physicians report a lack of self-perceived competency, a desire for education, and a need for improvement in primary care for children with autism. Physician education is needed to improve primary care for children with autism. Practice parameters and models of care should address physician-reported barriers to care.

Health-risk behaviors and protective factors among adolescents with mobility impairments and learning and emotional disabilities

PURPOSE To identify the risk involvement of three groups of young people with disabilities relative to a comparison group: mobility impairments, learning disabilities, and emotional disabilities. Protective factors are explored to identify which individual, family, and school factors are associated with diminished risk. METHODS Analyses are based on the National Longitudinal Study of Adolescent Health (Add Health), a nationally representative sample of 20,780 seventh- through 12(th)-grade youth in the United States. Five negative health outcomes were studied: suicide attempts, sexual abuse, regular cigarette smoker, alcohol use, and marijuana use. For bivariate analyses Students t-test and Chi-square were used, and logistic regressions were performed on all dichotomized dependent variables. RESULTS For most risk behaviors studied, youth with disabilities were more involved than peers. Factors that predisposed to risk varied little between those with and without disabilities. Likewise, there was substantial consistency between groups as to protective factors. What distinguished each group of young people with disabilities from peers is that they reported significantly more exposure to risk factors and significantly fewer protective factors.

Smoking among American adolescents: a risk and protective factor analysis.

Cigarette smoking remains a substantial threat to the current and future health of Americas youth. The purpose of this study was to identify the risk and protective factors for cigarette smoking among US adolescents. Data from the National Longitudinal Study of Adolescent Health was used, comparing the responses of all non-smokers at Time 1 for their ability to predict the likelihood of smoking at Time 2, one year later. Data was stratified into four gender by grade group cohorts. Cross-cutting risk factors for smoking among all four cohorts were: using alcohol, marijuana, and other illicit drugs; violence involvement; having had sex; having friends who smoke and learning problems. Having a higher grade point average and family connectedness were protective across all cohorts. Other gender and grade group specific risk and protective factors were identified. The estimated probability of initiating smoking decreased by 19.2% to 54.1% both in situations of high and low risk as the number of protective factors present increased. Of the factors that predict or protect against smoking some are influential across all gender and grade group cohorts studied, while others are specific to gender and developmental stage. Prevention efforts that target both the reduction of risk factors and enhancement of protective factors at the individual, family, peer group and community are likely to reduce the likelihood of smoking initiation.

Protective correlates of stages in adolescent substance use: a Swiss National Study

OBJECTIVE To identify factors potentially protective against involvement with additional illicit drugs among adolescent users of marijuana. DESIGN AND METHODS A cross-sectional, secondary analysis of a national data set of Swiss adolescents was performed. The original survey was conducted in 1992-1993 (N= 9268). Stages of substance use were conceptualized as lifetime use of marijuana of three or more times and as use of marijuana and other illicit drugs (opiates, inhalants, cocaine, hallucinogens, or stimulants) more than twice in the past month. Behavioral characteristics associated with level of drug use were examined. Based on the resilience literature, factors potentially protective against progression of drug use were examined in their bivariate relationships and analyzed in a multiple regression model. RESULTS Almost one quarter of the surveyed adolescents were classified as past or current marijuana users. One in 20 of these adolescents also used other illicit drugs. Prevalence of risk-related behaviors (e.g., antisocial behavior, accidents, suicide attempts) was elevated for marijuana users compared to nonusers and even more elevated for users of marijuana with other illicit drugs. In a multivariate logistic regression model, communicating well with a parent was significantly associated with not having progressed to use of illicit drugs other than marijuana [for males, odds ratio (OR) = 0.72, confidence interval (CI) = 0.55, 0.92; for females, OR = 0.60, CI = 0.39, 0.93]. Other significant protective correlates for boys were academic achievement (OR = 0.66, CI = 0.47, 0.92), type of education: school versus apprenticeship (OR = 0.42, CI = 0.21, 0.87), confiding in a family member (OR = 0.49, CI = 0.28, 0.85), and regular participation in a sports club (OR = 0.39, CI = 0.22, 0.77). CONCLUSION Within this national sample of Swiss adolescents, a cross-sectional analysis identified the quality of relationships within the family and factors related to school associated with lack of progression of illicit substance use. However, longitudinal studies will be necessary to confirm these associations and to allow for designing interventions targeting the enhancement of protective factors among young people already at risk for serious substance use.
