BACKGROUND Physical inactivity is a global pandemic. The population attributable fraction (PAF) of type 2 diabetes mellitus (T2DM) associated with physical inactivity ranges from 3% to 40%. The purpose of this systematic review was to determine the best estimate of PAF for T2DM attributable to physical inactivity and absence of sport participation or exercise for men and women. METHODS We con...

Lifetime physical inactivity interacts with secondary aging (i.e., aging caused by diseases and environmental factors) in three patterns of response. First, lifetime physical inactivity confers no apparent effects on a given set of physiological functions. Second, lifetime physical inactivity accelerates secondary aging (e.g., speeding the reduction in bone mineral density, maximal oxygen consu...

OBJECTIVE To estimate the total economic burden of physical inactivity in China. METHOD The costs of physical inactivity combine the medical and non-medical costs of five major Non Communicable Diseases (NCDs) associated with inactivity. The national data from the Chinese Behavioral Risk Factors Surveillance Surveys (2007) and the National Health Service Survey (2003) are used to compute popu...

BACKGROUND The purpose of this study was to investigate the association between physical inactivity and academic record in Korean adolescents. METHODS Adolescent students from the first grade of middle school to the third grade of high school (n=75,066) participated in the 5th Korea Youth Risk Behavior Web-based Survey project in 2009. The association between physical inactivity and academic ...

INTRODUCTION The aims of this study were to estimate all-cause and cause-specific mortality and years of life lost, investigated by disability-adjusted life-years (DALYs), due to colorectal cancer attributable to physical inactivity in Brazil and in the states; to analyze the temporal trend of these estimates over 25 years (1990-2015) compared with global estimates and according to the socioeco...

The aim of this study was to analyze gender and age differences in physical inactivity in Croatia and physical inactivity pattern changes during the five-year period. The study is based on the data obtained from the Croatian Adult Health Cohort Study which was carried out in 2003 and 2008. The prevalence of physical inactivity in 2008 was 37.7%, 36.8% in men and 38.1% in women. In both study wa...

CONTEXT AND OBJECTIVES Accelerometry provides objective measurement of physical activity levels, but is unfeasible in clinical practice. Thus, we aimed to identify physical fitness tests capable of predicting physical inactivity among adults. DESIGN AND SETTING Diagnostic test study developed at a university laboratory and a diagnostic clinic. METHODS 188 asymptomatic subjects underwent ass...

This study sought to investigate the prevalence of physical inactivity and related barriers in older Brazilian adults. A cross-sectional, population-based study was conducted, and a stratified random sampling procedure was used. A total of 359 older adults were interviewed. The long version of the International Physical Activity Questionnaire (IPAQ) and the Questionnaire of Barriers to Physical...
