INTRODUCTION Little is known about the relation between duration of physical activity and obesity. The objective of this study was to compare the effects of physical activity in bouts (> or = 10 minutes) to the effects of physical activity in nonbouts (<10 minutes) on markers of obesity. METHODS We used data from the 2003-2004 National Health and(More)
In this study, we used the conceptual Health Promotion Model to identify predictors of hearing protection use among blue-collar workers (N = 504). The strongest predictors were self-efficacy, benefits, value, and barriers. Items in the barriers scale were most strongly correlated with use and had the greatest potential for change. Therefore, items from this(More)
BACKGROUND Similar to patients with other chronic disorders, patients with serious mental illness (SMI) are often poorly adherent with prescribed medications. OBJECTIVE We conducted a randomized controlled trial examining the effectiveness of a pharmacy-based intervention (Meds-Help) in increasing antipsychotic medication adherence among Department of(More)
PURPOSE Our prior work has shown that the health behaviors of head and neck cancer patients are interrelated and are associated with quality of life; however, other than smoking, the relationship between health behaviors and survival is unclear. PATIENTS AND METHODS A prospective cohort study was conducted to determine the relationship between five(More)
In this project we tested the effectiveness of a theory-based intervention (video, pamphlets, and guided practice session) to increase the use of hearing protection devices (HPDs) among Midwestern construction workers and a national group of plumber/pipefitter trainers. Posttest measures were collected 10-12 months following this intervention. Pender's(More)
BACKGROUND Recent research indicates that 35 percent of blue-collar workers in the US currently smoke while only 20 percent of white-collar workers smoke. Over the last year, we have been working with heavy equipment operators, specifically the Local 324 Training Center of the International Union of Operating Engineers, to study the epidemiology of smoking,(More)
The purpose of this cross-sectional survey study was to examine the influence of self-efficacy, outcome expectations, and environment on neighborhood walking in older adults with (n = 163, mean age = 78.7, SD = 7.96 years) and without (n = 163, mean age = 73.6, SD = 7.93 years) mobility limitations, controlling for demographic characteristics. Multiple(More)
BACKGROUND A valid assessment of hearing status is important to detect hearing loss early and prevent further loss in noise-exposed individuals or older adults. Self-report is used widely in research and is often the only possible measure to evaluate hearing ability. OBJECTIVES The aims of this study were to establish the level of validity of self-rated(More)
BACKGROUND Three decades of research findings have documented the health effects of handling hazardous drugs. Oncology nurses are vulnerable due to frequent administration of antineoplastics, low adherence to equipment use, reported barriers to use, and perceived low risk of health effects. No interventions have been tested in a controlled, multi-site trial(More)
BACKGROUND Hearing loss and tinnitus are prevalent in America, and noise-induced hearing loss is a leading cause of hearing loss. Noise-induced hearing loss has negative impact on quality of life, physical and emotional functioning, social life, and employment. In addition, noise-induced hearing loss results in heavy social and economic burdens on families(More)
