Physical Activity Measurements (physical + activity_measurement)
Selected AbstractsClinical use of physical activity measuresJOURNAL OF THE AMERICAN ACADEMY OF NURSE PRACTITIONERS, Issue 2 2009CRNP (Associate Professor), Lorraine M Reiser PhD Abstract Purpose:, To provide a review of physical activity measures and subjective and objective methods of its measurement. Considerations for the use of these measurements in research and practice will be discussed. Data sources:, The PubMed, CINAHL, and Health and Psychosocial Instruments databases, and the Centers for Disease Control Web site were searched using the search term "Physical Activity Measurement." Conclusions:, Physical activity is a lifestyle factor that is a key focus in chronic disease,related research, prevention, and interventions. Healthy People 2010 set goals of decreasing the prevalence of preventable diseases by encouraging healthier lifestyle patterns. Shifts toward more sedentary lifestyles have resulted in increases in life-limiting disease states, including obesity, diabetes, heart disease, cancer, and osteoporosis. Physical activity measurements have been used widely in research studies but are less commonly used in primary care. Measuring individuals' physical activity levels as part of the health assessment will enhance the provider's ability to engage in health promotion and suggest health protection interventions. The strengths, weaknesses, and potential applications to practice of physical activity measures are summarized in an effort to familiarize nurse practitioners (NPs) with commonly used tools and encourage integration of physical activity assessment into their current practice. Implications for practice:, NPs are in an ideal position to promote health by encouraging appropriate amounts of physical activity. Screening, health promotion, and disease prevention are part of the core competencies of NP practice established by the National Organization of Nurse Practitioner Faculties. Increased knowledge of physical activity measures will enhance the NP's ability to evaluate relevant physical activity research for use in evidence-based practice. Incorporation of simple yet appropriate physical activity measurements into practice will expand the NP's ability to identify and thus address sedentary lifestyles in their clientele. [source] A quantitative analysis of energy intake reported by young menNUTRITION & DIETETICS, Issue 4 2008Selma C. LIBERATO Abstract Aim:, To quantitatively analyse energy intake reported by young men and the accuracy of the Goldberg cut-off method for identifying misreporters. Methods:, This was a cross-sectional study in which: food intake was assessed by a four-day food record; resting metabolic rate was assessed by indirect calorimetry; percentage body fat was measured by dual-energy X-ray absorptiometry; and energy expenditure was assessed by physical activity record completed simultaneously with food intake measurements. Energy intake was analysed by direct comparison of energy intake and energy expenditure and by the Goldberg cut-off. Subjects: 34 healthy men aged 18,25 years. Setting: Queensland University of Technology, Queensland, Australia. Main outcome measures: percentage of misreporters in a group of young men using different methods. Statistical analyses: data are presented as means and standard deviations. The analyses were conducted using Statistic for Windows 5.5 software. Results:, Seven underreporters were identified by direct comparison of energy intake and energy expenditure. The Goldberg cut-off found six out of the seven underreporters identified by direct comparison of energy intake and energy expenditure, but wrongly identified two acceptable reporters as underreporters. The sensitivity and specificity of the Goldberg cut-off method were 0.86 and 0.93, respectively. Conclusions:, Seven out of 34 participants underreported their energy intake. In the absence of physical activity measurements, the Goldberg cut-off method identified underreporters in this group of young men with assessed resting metabolic rate. [source] | ||||||||||
