BACKGROUND Prolonged sitting time is a health risk. We describe a practice-based study designed to reduce prolonged sitting time and improve selected health factors among workers with sedentary jobs. COMMUNITY CONTEXT We conducted our study during March-May 2011 in Minneapolis, Minnesota, among employees with sedentary jobs. METHODS Project(More)
OBJECTIVE Although major depression is thought to have substantial negative effects on work performance, the possibility of recall bias limits self-report studies of these effects. The authors used the experience sampling method to address this problem by collecting comparative data on moment-in-time work performance among service workers who were depressed(More)
BACKGROUND Many health behaviors and physiologic indicators can be used to estimate one's likelihood of illness or premature death. Methods have been developed to assess this risk, most notably the use of a health-risk assessment or biometric screening tool. This report provides recommendations on the effectiveness of interventions that use an Assessment of(More)
INTRODUCTION Physical inactivity, overweight, and obesity are associated with increased morbidity and mortality. The objective of this study was to estimate the proportion of total health care charges associated with physical inactivity, overweight, and obesity among U.S. populations aged 40 years and older. METHODS A predictive model of health care(More)
Cardiometabolic risk (CMR), also known as metabolic syndrome or insulin resistance syndrome, comprises obesity (particularly central or abdominal obesity), high triglycerides, low HDL, elevated blood pressure, and elevated plasma glucose. Leading to death from diabetes, heart disease, and stroke, the root cause of CMR is inadequate physical activity, a(More)
In 1991, Plsek sought to improve the quality of health care by challenging the readers of Crossing the Quality Chasm to find the few simple rules that might guide the local development of the 21st century health system. We have analyzed our health system's activities in the context of systems science as it seeks to create value (improve population health(More)
Since the early 1900s, the major causes of illness and death in the United States have changed from infectious disease to chronic disease. Recognition is growing that nonclinical community-and population-based prevention has a large role in improving the public's health and well-being. Health risks such as obesity, tobacco use, and low levels of physical(More)
BACKGROUND The study examined correlates of body mass index (BMI) in overweight and obese members of a managed care organization seeking treatment for obesity. It assessed intake of specific foods, dietary fat or fiber, and behaviors attempted to control weight. METHODS Participants were 508 men and 1293 women who were > 18 years and had a self-reported(More)
BACKGROUND Many adults in the United States report engaging in weight loss behaviors. The current study examined weight loss strategies among managed care organization members, to determine the prevalence and impact of weight loss behaviors in this population. We hypothesized that greater engagement in weight loss strategies would be associated with greater(More)
INTRODUCTION American health plans can make a substantial contribution to the control of cardiometabolic risk (CMR), a condition associated with both adverse health outcomes and increased cost of care. Our goal was to determine health plan interest in and ability to provide CMR control services. METHODS In January 2008, America's Health Insurance Plans,(More)
