Predictors of substance use among homeless youth in San Diego

Protective factors associated with fewer multiple problem behaviors among homeless/runaway youth

Although homeless youth exhibit numerous problem behaviors, protective factors that can be targeted and modified by prevention programs to decrease the likelihood of involvement in risky behaviors are less apparent. The current study tested a model of protective factors for multiple problem behavior in a sample of 474 homeless youth (42% girls; 83% minority) ages 12 to 24 years. Higher levels of problem solving and planning skills were strongly related to lower levels of multiple problem behaviors in homeless youth, suggesting both the positive impact of preexisting personal assets of these youth and important programmatic targets for further building their resilience and decreasing problem behaviors. Indirect relationships between the background factors of self-esteem and social support and multiple problem behaviors were significantly mediated through protective skills. The model suggests that helping youth enhance their skills in goal setting, decision making, and self-reliant coping could lessen a variety of problem behaviors commonly found among homeless youth.

Does proximity to retailers influence alcohol and tobacco use among Latino adolescents?

Despite decades of research surrounding determinants of alcohol and tobacco (A&T) use among adolescents, built environment influences have only recently been explored. This study used ordinal regression on 205 Latino adolescents to explore the influence of the built environment (proximity to A&T retailers) on A&T use, while controlling for recognized social predictors. The sample was 45% foreign-born. A&T use was associated with distance from respondents' home to the nearest A&T retailer (-), acculturation (+), parents' consistent use of contingency management (-), peer use of A&T (+), skipping school (+), attending school in immediate proximity to the US/Mexico border (+), and the interaction between the distance to the nearest retailer and parents' consistent use of contingency management (+). The association between decreasing distance to the nearest A&T retailer and increased A&T use in Latino adolescents reveals an additional risk behavior determinant in the US-Mexico border region.

Factors associated with substance use among homeless young adults

The purpose of this study was to investigate factors associated with substance use among homeless young adults. Multinomial logistic regression analyses examined the influence of social networks and economic factors among a group of homeless young adults with differing levels of alcohol and drug use. In addition, for those with an alcohol use disorder, the role of future time expectancies was examined. A sample (n = 185) of homeless young adults aged 18 to 23 were recruited from a community drop-in center and interviewed utilizing self-report instruments. Findings suggest that social networks, economic factors, and future expectancies are significant predictors of the level of substance use among homeless young adults. Being able to identify those areas that place homeless young adults at risk for substance abuse and dependence has implications for effective intervention.

That which does not kill you makes you stronger: runaway youth's resilience to depression in the family context

The present study sought to uncover the relationship between risk and protective factors for depressive symptomatology among runaway youth. To that aim, 3 models of resiliency-the compensatory, risk-protective, and challenge models-were tested separately on girls and boys. The data came from a cross-sectional survey on a sample of 140 runaway adolescents between the ages of 12 and 17 years who were recruited from the only runaway crisis shelter in a large Midwestern city. Risk factors in the proposed model included primary caretaker's depressive symptoms, family conflict, and adolescent's and primary caretaker's verbal aggression; protective factors included adolescent's report of task-oriented coping and family cohesion. Findings supported the challenge model for predicting adolescent depressive symptoms, suggesting that moderate levels of risk can be beneficial for these runaway adolescents. In addition, risk and protective factors differed by adolescent gender. Implications for preventive interventions and future research are discussed.

Predictors of weapon carrying in youth attending drop-in centers

OBJECTIVE

To test and compare 2 predictive models of weapon carrying in youth (n = 308) recruited from 4 drop-in centers in San Diego and Imperial counties.

METHODS

Both models were based on the Behavioral Ecological Model (BEM).

RESULTS

The first and second models significantly explained 39% and 53% of the variance in weapon carrying, respectively, and both full models shared the significant predictors of being black(-), being Hispanic (-), peer modeling of weapon carrying/jail time (+), and school suspensions (+).

CONCLUSIONS

Results suggest that the BEM offers a generalizable conceptual model that may inform prevention strategies for youth at greatest risk of weapon carrying.

Social Estrangement: Factors Associated with Alcohol or Drug Dependency among Homeless, Street-Involved Young Adults

Substance use is highly prevalent among homeless, street-involved young people. Societal estrangement is often associated with substance use, particularly among this population. The current study utilized a descriptive correlational design to identify four domains of social estrangement: disaffiliation, human capital, identification with homeless culture, and psychological dysfunction. These domains were tested to determine their association with alcohol or drug dependence. Interviews utilizing self-report instruments were conducted with 185 young adults aged 18–23 years of age who were receiving homeless services from a community drop-in center. In this sample, the vast majority reported high levels of alcohol and drug use with more than half being identified as dependent on alcohol and/or drugs. Polysubstance use was highly prevalent and most reported marijuana as their drug of choice. Findings indicate that identification with homeless culture was the most highly predictive domain of social estrangement for both alcohol and drug dependency. Implications for services to this population are discussed.

A comparison of weight-related behaviors among high school students who are homeless and non-homeless

BACKGROUND

Previous research has shown that youth who are homeless engage in high-risk behaviors. However, there has been little information published on nutritional and physical activity behaviors in this population, and studies comparing homeless youth in school with their non-homeless peers are scarce. This study compares weight-related risk behaviors of public high school students in Massachusetts based on homeless status.

METHODS

We obtained data from 3264 9th through 12th grade students who participated in the 2005 Massachusetts Youth Risk Behavior Survey. Multivariable logistic regression, controlling for gender, grade, race/ethnicity, and sexual orientation, was performed to assess the relationship between homeless status as defined by the McKinney-Vento Homeless Assistance Act and weight-related indicators. Analyses were weighted and adjusted for the multistage complex sampling design.

RESULTS

Of this sample, 4.2% reported being homeless (n = 152). Higher prevalence of homelessness was found among males, racial/ethnic minorities, sexual minorities, and students who were not in a traditional grade level. The distribution of body mass index was similar among students who were homeless and non-homeless (underweight 4.0 and 3.0%, and overweight 27.1 and 27.1%, respectively). Homeless students were more likely than non-homeless students to report disordered weight-control behaviors including fasting (aOR 2.5, 95% CI 1.4-4.5) and diet pill use (aOR 3.3, 95% CI 1.6-6.9).

CONCLUSIONS

More than 4% of public high school students in Massachusetts meet the federal definition of homelessness. These students are at high risk for disordered weight-control behaviors. Policy decisions at the school, state, and federal levels should make a concerted effort to target these students with social services and nutritional interventions.

Employment and social "determinants" of smoking in urbanizing China: a representative survey

INTRODUCTION

This study explored social determinants of smoking among a sample of male Chinese adults in Changqiao, a community representing the transition from traditional to a "mobile" urban culture in China. New commercial systems have introduced high profits but also layoffs in the absence of government security systems.

METHODS

In-person interviews were conducted by trained interviewers with 123 male participants selected at random. Bivariate and multivariate analyses were computed based on the Behavioral Ecological Model (BEM). About 61% of male participants were ever-smokers and 48% were current smokers.

RESULTS

Current smoking was associated with involuntary unemployment (odds ratio [OR] = 6.52), the absence of home smoking restrictions (OR = 0.34), and social reinforcement such as friends' smoking (OR = 4.02) and receiving smoking-related gifts (OR = 6.39).

DISCUSSION

Findings support the BEM. It is especially important to verify the relationship between unemployment and smoking, given the recent rise in involuntary job loss due to the transitional economy in China.

High rates of homelessness among a cohort of street-involved youth

Using multivariate logistic regression, we examined the prevalence and correlates of homelessness among youth enrolled in a community-recruited prospective cohort known as the At-Risk Youth Study (ARYS), between September 2005 and October 2006. Of 478 individuals included in this analysis, 132 (27.6%) were female and 120 (25.1%) self-identified as Aboriginal. The median age was 22 (IQR: 20-24). In total, 284 (56.9%) participants reported baseline homelessness, with most living either at no fixed address, on the street, or in a hostel or shelter. Factors associated with homelessness included public injecting, frequent crack use, experienced violence, having less than a high-school education, and not having been in any addiction treatment. Homeless individuals were at-risk for various adverse health outcomes. These findings indicate the need for additional interventions, including residential addiction treatment, to address homelessness and drug use among youth.

Assessing and quantifying high risk: comparing risky behaviors by youth in an urban, disadvantaged community with nationally representative youth

OBJECTIVE

This study examined whether youth who live in an urban, disadvantaged community are significantly more likely than youth representing the nation to engage in a range of health-compromising behaviors.

METHODS

Analyses were based on the Youth Violence Survey conducted in 2004 and administered to students (n=4131) in a high-risk school district. Students in ninth grade (n=1114) were compared with ninth-grade students in the 2003 national Youth Risk Behavior Survey (n=3674) and the National Longitudinal Study of Adolescent Health conducted in 1995/1996 (n=3523). Analyses assessed the differences in prevalence of risk and protective factors among ninth-grade students from the three studies using Chi-square tests.

RESULTS

The results showed that youth in this urban, disadvantaged community were significantly more likely than their peers across the country to report vandalism, theft, violence, and selling drugs. Youth in this community also reported significantly less support from their homes and schools, and less monitoring by their parents. Moreover, youth in this community were significantly less likely to binge drink or initiate alcohol use prior to age 13 than youth across the U.S.

CONCLUSIONS

Youth who live in this urban, disadvantaged community reported significantly higher prevalence of some, but not all, risky behaviors than nationally representative U.S. youth. These findings highlight that some caution is justified when defining what might constitute high risk and that demographic and other characteristics need to be carefully considered when targeting certain high-risk behaviors.

Caring for and connecting with homeless adolescents

Adolescents from a variety of backgrounds are among the growing number of homeless Americans. Although they lack maturity and various skills, they manage to survive in dangerous and stressful environments. This article asserts that social policy that leads to services such as housing, education, and healthcare should be based on a philosophy, ethic, and theory of caring and connectedness, which have been shown to protect adolescents as they mature. The article includes brief descriptions of theories of caring, pathways to homelessness for adolescents, survival needs of homeless youth, and characteristics of service programs that incorporate caring and connectedness.

Sexual and drug use risk behaviors among children and youth in street circumstances in Porto Alegre, Brazil

We conducted a cross-sectional study to assess sexual and drug use risk in 161 children and youth in street circumstances in Porto Alegre, Brazil. Median age was 14 and 79% were male. Overall, 59% reported ever having had sex; a significantly higher proportion of males (66%) compared to females (30%). Overall, 39% reported illicit drug use in the last year, and only 1.2% reported injection drug use. In multivariate analyses, correlates of unsafe sex included younger age of sexual debut, and having a steady sex partner. Independent correlates of illicit drug use included lack of family contact, increased hours in the street daily, having had an HIV test, and older age. A high proportion of children and youth in street circumstances reported high risk sex and drug exposures, confirming their vulnerability to HIV/STD. Services Centers, such as where this research was carried out, offer an opportunity for interventions.
