To guide skin cancer preventive interventions, this study examined correlates of sun safety behaviors in a racially and ethnically diverse sample of 407 adolescents completing a self-report survey at the time of their pediatric wellness visit. Adolescents regularly practiced few sun safety behaviors, and greater interest in cancer prevention was associated with more sun safety behaviors, ever smoking cigarettes was associated with fewer sun safety behaviors, and nonwhite minority adolescents practiced fewer sun safety behaviors than non-Hispanic whites. Clinical preventive interventions to increase sun safety practices among adolescents of all racial and ethnic backgrounds could be integrated into general cancer prevention education, including combining skin cancer prevention with antismoking counseling.

Treatments for childhood cancer can impair pulmonary function. We assessed the potential impact of cigarette smoking on pulmonary function in 433 adult childhood cancer survivors (CCS) who received pulmonary-toxic therapy, using single breath diffusion capacity for carbon monoxide corrected for hemoglobin (DLCOcorr), forced expiratory volume in 1 second (FEV1), forced vital capacity (FVC), and total lung capacity (TLC). FEV1/FVC median values among current [1.

Tobacco use and exposure are preventable causes of morbidity and mortality. Whereas the impact of this public health issue is well described in adults with kidney disease, its role in the pediatric chronic kidney disease (CKD) population is largely unknown. This review discusses the prevalence of tobacco use and exposure in children with CKD, updates the reader on how tobacco affects the kidney, and presents intervention strategies relevant to this patient population.

Objectives: Elevated body mass index (BMI) has been reported in pediatric cancer survivors. It is unclear whether this is related to altered energy intake (via disordered eating), decreased energy expenditure (via limited exercise), or treatment-related direct/indirect changes. The aims of this study are to describe the occurrence of overweight and obesity, exercise frequency, and the extent of disordered eating patterns in this sample of survivors, and to examine relationships among BMI, eating patterns, exercise frequency, and demographic and disease and treatment-related variables to identify those survivors most at risk for overweight/obesity.

Background: Adolescent survivors of childhood cancer are more vulnerable to the consequences of health risk behaviors because of the late effects of their disease and its treatment. Decision making related to risk behaviors is important as they have reached an age during which initiation of substance use risk behavior is common.

Objective: Factors associated with decision making and substance use behaviors (smoking, alcohol use, and illicit drug use) were identified among adolescent survivors of childhood cancer, the role of cognitive function was examined, and their rates of substance use behaviors were compared to a sample from the general population.
