ResumoIn spite of the growing use of motion sensors, particularly accelerometers, for the measurement of physical activity in high-income countries,1 virtually all population-based physical activity studies from lowand middle-income countries (LMICs) still rely on selfreport.2,3 In addition to the well known financial aspect of this inequality, availability of trained personnel is another challenge in LMICs. Also, less widely known barriers, such as importation regulations also play a role.4 The measurement of physical activity in LMICs is particularly challenging. First, literacy issues need to be taken into account; low literacy makes self-administration of instruments in population-based samples virtually impossible. Second, the low coverage of telephone lines in several areas makes it unfeasible to conduct phone survey; for example, the Brazilian phone surveillance system takes place in state capitals only. Third, internet access is still a luxury in several parts of the world, and therefore, computer-based instruments are unlikely to be appropriate for large scale studies in LMICs.5 Over the last years, a series of papers tried to highlight underlying principles of physical activity measurement. However, most were developed in high-income countries and very little was said on the measurement of physical activity in LMICs. Some aspects that deserve special consideration are
