Abstract Active commuting study and promotion are increasing globally, given the strong association between active commuting and current public health problems, like obesity and global warming, and given its potential contribution to crucial areas, such as transportation, health and environment. Thus, the objective of our study was to investigate the frequency, distribution and time trend of active commuting in Brazil, as well as its effects on health conditions.First of all, considering the global epidemic of obesity, an investigation of the relation between active commuting and health conditions will be conducted by a systematic review. Four databases will be used: PubMed, Web of Knowledge, CAB Abstracts and LILACS. We will select original articles, independent of the study design, with data concerning the association between active commuting practice and overweight, published in English, Portuguese, and Spanish. Whenever possible, the results will be combined and the association between active commuting and overweight will be estimated. Before that, the analysis of the heterogeneity of the studies will be performed using the I2 statistics. In case of heterogeneity, we will investigate the causes by stratifying the studies according to their design and possible publication bias, using graph analysis (funnel plot) and Egger's test. The second part of the project consists of an evaluation of the frequency and distribution of commuting in Brazil, based on the current literature, with the data source of the Health Supplement of the Household National Survey 2008. We will expand on the indicators of active commuting, considering also the active commuting to work with less than 30 minutes a day, and we will include new variables of stratification, such as place of residence and federal units. In the third part of the study, we intend to investigate the patterns of commuting in Sao Paulo Metropolitan Area (SPMA) and the relation of active commuting and other forms of transportation. We will use as the data source Household Travel Surveys (HTS) 1997 and 2007. HTS aim to characterize the dynamics of diary commuting in certain regions with the objective of planning the expansion and restructuring of the transport network. HTS provide data concerning modes of commuting, distance, time spent with each commuting, origin, destination, and the purpose of the trip. In HTS, the trip is defined as the entire route between origin and destination, which can be accomplished with different modes of transport. Since our main interest lies in the active modes of transportation, we will consider each part as a different trip. Then, we will explore data of commuting in SPMA by two different strategies: the first one, considering the trip as the study unit, and, the second one, the individuals. The frequency, distribution and time trend of health indicators and conditions between 1997 and 2007 will be evaluated.The last part of the project aims to identify the independent effect of active commuting practice to work on overweight in the adult Brazilian population, with data of Telephone-based System for the Surveillance of Risk and Protective Factors for Chronic Diseases, from 2006 to 2010, considering sociodemographic, other physical activity domains, sedentarism, health conditions like tobacco use, heavy alcohol drinking, and variables of food intake. | |
