Objectives. We describe the lifetime prevalence and associated health-related concerns of family homelessness among fifth-grade students. Methods. We used a population-based, cross-sectional survey of 5147 fifth-grade students in 3 US cities to analyze parent-reported measures of family homelessness, child health status, health care access and use, and emotional, developmental, and behavioral health and child-reported measures of health-related quality of life and exposure to violence. Results. Seven percent of parents reported that they and their child had experienced homelessness (i.e., staying in shelters, cars, or on the street). Black children and children in the poorest families had the highest prevalence of homelessness (11%). In adjusted analyses, most general health measures were similar for children who had and had not been homeless. Children who had ever experienced homelessness were more likely to have an emotional, behavioral, or developmental problem (odds ratio [OR] = 1.7; 95% confidence interval [CI] = 1.1, 2.6; P = .01), to have received mental health care (OR = 2.2; 95% CI = 1.6, 3.2; P < .001), and to have witnessed serious violence with a knife (OR = 1.6; 95% CI = 1.1, 2.3; P = .007) than were children who were never homeless. Conclusions. Family homelessness affects a substantial minority of fifth-grade children and may have an impact on their emotional, developmental, and behavioral health.

Objectives. We sought to describe the prevalence, characteristics, and mental health problems of children who experience perceived racial/ethnic discrimination. Methods. We analyzed cross-sectional data from a study of 5147 fifth-grade students and their parents from public schools in 3 US metropolitan areas. We used multivariate logistic regression (overall and stratified by race/ethnicity) to examine the associations of sociodemographic factors and mental health problems with perceived racial/ethnic discrimination. Results. Fifteen percent of children reported perceived racial/ethnic discrimination, with 80% reporting that discrimination occurred at school. A greater percentage of Black (20%), Hispanic (15%), and other (16%) children reported perceived racial/ethnic discrimination compared with White (7%) children. Children who reported perceived racial/ethnic discrimination were more likely to have symptoms of each of the 4 mental health conditions included in the analysis: depression, attention deficit hyperactivity disorder, oppositional defiant disorder, and conduct disorder. An association between perceived racial/ ethnic discrimination and depressive symptoms was found for Black, Hispanic, and other children but not for White children. Conclusions. Perceived racial/ethnic discrimination is not an uncommon experience among fifth-grade students and may be associated with a variety of mental health disorders. doi:10.2105/AJPH.2008.144329)

Objectives. We investigated the association between physical and social neighborhood environments and fifth-grade students' physical activity and obesity. Methods. We collected data on 650 children and their primary caregivers during phase 1 of Healthy Passages, a multisite, community-based, cross-sectional study of health risk behaviors and health outcomes in children. We conducted independent systematic neighborhood observations to measure neighborhood physical characteristics, and we analyzed survey data on social processes. We modeled children's physical activity and obesity status with structural equation models that included latent variables for the physical and social environments. Results. After we controlled for children's sociodemographic factors, we found that a favorable social environment was positively associated with several measures of physical activity and that physical activity was negatively associated with obesity in these children. Physical environment was not significantly associated with physical activity. Conclusions. Our findings suggest that neighborhood social factors as well as the physical environment should be considered in the development of health policy and interventions to reduce childhood obesity.
