BACKGROUND Little is known about physical activity and sedentary behavior of adults with bipolar disorder (BP). Physical activity and sedentary behaviors may be modifiable factors associated with elevated rates of obesity, diabetes, cardiovascular disease, metabolic syndrome, and mortality in adults with BP. METHODS Sixty adult outpatients treated for BP(More)
BACKGROUND This study examined the independent association of objectively measured physical activity on insulin resistance while controlling for confounding variables including: cardiorespiratory fitness, adiposity, sex, age, and smoking status. METHODS Data were obtained from National Health and Nutrition Examination Survey 2003-2004, a cross-sectional(More)
BACKGROUND Engaging in regular physical activity can be challenging, particularly during the winter months. To promote physical activity at the University of Michigan during the winter months, an eight-week Internet-mediated program (Active U) was developed providing participants with an online physical activity log, goal setting, motivational emails, and(More)
BACKGROUND Accelerometers were incorporated in the 2003-2004 National Health and Nutritional Examination Survey (NHANES) study cycle for objective assessment of physical activity. This is the first time that objective physical activity data are available on a nationally representative sample of U.S. residents. The use of accelerometers allows researchers to(More)
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)
BACKGROUND Low levels of physical activity (PA) are associated with poor outcomes in people with COPD. Interventions to increase PA could improve outcomes. METHODS We tested the efficacy of a novel Internet-mediated, pedometer-based exercise intervention. Veterans with COPD (N = 239) were randomized in a 2:1 ratio to the (1) intervention group (Omron(More)
BACKGROUND Weight-loss trials tend to recruit highly selective, non-representative samples. Effective weight-loss approaches are needed for real-world challenging populations. PURPOSE To test whether a small-changes intervention, delivered in groups or via telephone, promotes greater weight loss than standard obesity treatment in a predominantly male,(More)
BACKGROUND Little is known about frailty in people with chronic obstructive pulmonary disease (COPD). The purposes of this study were to describe frailty, to identify, which demographic and clinical characteristics contributed to frailty, and to examine the relationship between frailty and health-related outcomes in people with COPD. METHODS This was a(More)
OBJECTIVE To determine whether the presence or severity of pain is predictive of suboptimal weight loss outcomes in behavioral weight management programs. METHODS This is a secondary data analysis comparing weight loss among participants with overweight/obesity who participated in a 12-month randomized controlled trial. Of the 481 participants randomized,(More)
OBJECTIVE To assess for the frequency of binge eating behavior and its association with weight loss in an overweight/obese sample of veterans. METHODS This study is a secondary analysis of data from the ASPIRE study, a randomized effectiveness trial of weight loss among veterans. Of the 481 enrolled veterans with overweight/obesity, binge eating frequency(More)
