Skin cancer is the most common type of cancer, and is also one of the most preventable. This paper builds on an evidence review of skin cancer prevention interventions that was conducted for the Guide to Community Preventive Services (n=85 studies), and summarizes the state of knowledge about research methodology and measurement in studies of the(More)
OBJECTIVE Farm workers are exposed to long hours of solar ultraviolet radiation (UVR), placing them at higher risk for skin cancer. The goal of this study was to evaluate farm workers' sun exposure behaviors. METHODS Farm workers (n=326) in the San Joaquin Valley of California were interviewed about their sun protective behaviors; these behaviors also(More)
BACKGROUND Dog walking is a strategy for increasing population levels of physical activity (PA). Numerous cross-sectional studies of the relationship between dog ownership and PA have been conducted. The purpose was to review studies comparing PA of dog owners (DO) to nondog owners (NDO), summarize the prevalence of dog walking, and provide recommendations(More)
Objectives United States Postal Service letter carriers are exposed to long bouts of UVR and thus are vulnerable to skin cancer. While previous studies have shown that occupational sun protection is often deficient, few studies have examined outdoor workers’ behavior during leisure time. Methods Subjects (n = 2,660) self-reported widebrim hat and sunscreen(More)
OBJECTIVES We examined whether US Postal Service letter carriers who received a sun safety intervention would wear wide-brim hats and sunscreen significantly more often than those who did not receive the intervention. METHODS We used a 2-group randomized design with 2662 evaluation cohort participants from 70 US postal stations. Evaluations were conducted(More)
OBJECTIVES We evaluated psychosocial, built-environmental, and policy-related correlates of adolescents' indoor tanning use. METHODS We developed 5 discrete data sets in the 100 most populous US cities, based on interviews of 6125 adolescents (aged 14-17 years) and their parents, analysis of state indoor tanning laws, interviews with enforcement experts,(More)
PURPOSE This study assessed the rates and correlates of adolescents' compliance with national guidelines for physical activity. METHODS A cross-sectional phone survey of adolescents and their parents was conducted in the 100 largest cities in the United States in 2005.

OBJECTIVE We examined the prevalence and correlates of dog walking among dog owners, and whether dog walking is associated with meeting the American College of Sports Medicine/American Heart Association physical activity guidelines. METHODS In March 2008, we mailed a survey to dog-owning clients from two San Diego County veterinary clinics. Useable data(More)
BACKGROUND Few sun-safety studies have included ethnoracially diverse groups. Comparison across such groups of sun-safety behaviors was the main objective of this analysis. METHODS Postal workers (n =2543) self-reported frequency of sunscreen, wide-brim hat, and sunglasses use during the last 5 workdays on 5-point Likert-type scales ranging from "never"(More)
