Prevalence of active transportation among adults in Latin America and the Caribbean: a systematic review of population-based studies.

Objective: To describe the prevalence of "active" (self-propelled, human-powered) transportation in the Latin America and Caribbean (LAC) region over the past decade.

Methods: MEDLINE, Excerpta Medica (Embase), SportDiscus, Lilacs, MediCarib, Web of Science, OVID, CINAHL, Scopus, Google Scholar, National Transportation Library, and TRIS/TRID were searched for articles on active transportation published between January 2003 and December 2014 with (at least) a title and abstract in English, Portuguese, or Spanish. Research was included in the study if the two reviewing authors agreed it 1) was conducted in an adult sample (≥ 18 years old), 2) was designed to be representative of any LAC area, and 3) reported at least one measure of active transportation.
