Leisure time physical activity and mortality.

TLDR
Mortality was lower with participation in specific leisure time physical activities, but not with more time spent on those activities, which could suggest that avoiding a sedative lifestyle is more important than a high volume of activity.Abstract:
Background:Some studies indicate that a large part of the beneficial effect of physical activity on mortality is confined to a threshold effect of participation.Methods:Self-reported physical activity was investigated in relation to all-cause mortality in the Danish Diet, Cancer and Health cohort, iread more

Systematic review and meta-analysis of reduction in all-cause mortality from walking and cycling and shape of dose response relationship
Paul Kelly,Paul Kelly,Sonja Kahlmeier,Thomas Götschi,Nicola Orsini,Justin Richards,Nia Roberts,Peter Scarborough,Charlie Foster +8 more
TL;DR: The analysis shows that walking and cycling have population-level health benefits even after adjustment for other physical activity (PA), and public health approaches would have the biggest impact if they are able to increase walked and cycling levels in the groups that have the lowest levels of these activities.

Air pollution, physical activity and health: A mapping review of the evidence

TL;DR: Current evidence of AP and PA interactions for health is reviewed and it is suggested that PA behaviour and health effects might be moderated by AP exposure.

A study of the combined effects of physical activity and air pollution on mortality in elderly urban residents: the Danish diet, cancer, and health cohort
Zorana Jovanovic Andersen,Audrey de Nazelle,Michelle A. Mendez,Judith Garcia-Aymerich,Ole Hertel,Anne Tjønneland,Kim Overvad,Kim Overvad,Ole Raaschou-Nielsen,Mark J. Nieuwenhuijsen +9 more
TL;DR: Exposure to high levels of traffic-related air pollution did not modify associations, indicating beneficial effects of physical activity on mortality, and replication in other study populations require replication.

Physical Activity, Air Pollution, and the Risk of Asthma and Chronic Obstructive Pulmonary Disease
Jack E. Fisher,Steffen Loft,Charlotte Suppli Ulrik,Ole Raaschou-Nielsen,Ole Hertel,Anne Tjønneland,Kim Overvad,Kim Overvad,Mark J. Nieuwenhuijsen,Zorana Jovanovic Andersen +9 more
TL;DR: Increased exposure to air pollution during exercise does not outweigh beneficial effects of physical activity on the risk of asthma and COPD, and interaction terms between each physical activity and NO2 are introduced.

State of the art in selection of variables and functional forms in multivariable analysis—outstanding issues
Willi Sauerbrei,Aris Perperoglou,Matthias Schmid,Michal Abrahamowicz,Heiko Becher,Harald Binder,Daniela Dunkler,Frank E. Harrell,Patrick Royston,Georg Heinze +9 more
TL;DR: There is not yet enough evidence on which to base recommendations for the selection of variables and functional forms in multivariable analysis, and seven important topics that require further investigation are highlighted.

Physical Fitness and All-Cause Mortality: A Prospective Study of Healthy Men and Women
Steven N. Blair,Harold W. Kohl,Ralph S. Paffenbarger,Debra G. Clark,Kenneth H. Cooper,Larry W. Gibbons +5 more
TL;DR: Higher levels of physical fitness appear to delay all-cause mortality primarily due to lowered rates of cardiovascular disease and cancer, and lower mortality rates in higher fitness categories also were seen for cardiovascular Disease and cancer of combined sites.

TL;DR: Benefits of a range of volumes of physical activity in a Taiwanese population between 1996 and 2008 were applicable to all age groups and both sexes, and to those with cardiovascular disease risks.

All-cause mortality associated with physical activity during leisure time, work, sports, and cycling to work
TL;DR: Leisure time physical activity was inversely associated with all-cause mortality in both men and women in all age groups, and benefit was found from moderate leisure timephysical activity, with further benefit from sports activity and bicycling as transportation.

TL;DR: Two classes of simple alternatives that can be implemented with any regression software: fractional polynomial regression and spline regression are described, illustrated in a problem of estimating historical trends in human immunodeficiency virus incidence.

TL;DR: The summary index of physical activity derived from the questions used in the European Prospective Investigation into Cancer and Nutrition (EPIC) study suggest it is useful for ranking participants in terms of their physical activity in large epidemiological studies.
