Levels of physical activity and associated factors between military policemen and firemen.

BACKGROUND: Military Policemen and Firemen are professionals often involved in life-risking activities as well as duties demanding endurance and muscular strength. Nevertheless, their working conditions are rarely satisfactory. OBJECTIVE: To compare levels of physical activity and social, demographic and occupational factors between military policemen and firemen; factors that may impact their ability to efficiently and effectively accomplish their jobs. METHODS: This cross-sectional study was performed in Brazil with 127 local military personnel (67 policemen and 60 firemen). A sociodemographic questionnaire was applied together with the International Physical Activity Questionnaire (IPAQ), short version. RESULTS: It was observed that the firemen participating in this study are 4 times more likely to be inactive than the policemen. However, policemen showed higher sociodemographic risk factors (less schooling and the higher number of children and workplaces) to work performance when compared to military firemen. CONCLUSION: It could be inferred that in relation to the firemen, policemen suffer from less favorable sociodemographic conditions and face major risk situations more frequently once they are directly involved with the public security of the States; on the other hand, both populations should be incentivized and offered systematized physical activity programs in their workplaces.

[Collective health, territorial and environmental conflicts: bases for a critical socio-environmental approach]. / Saúde coletiva, território e conflitos ambientais: bases para um enfoque socioambiental crítico.

The phenomenon of globalization and the increase in neo-extractivism in the global periphery intensify the search for new territories and natural resources for the economy, resulting in significant impacts on ecosystems and on the lives of vulnerable populations. It is considered that the environmental crisis imposes new challenges and requires an updating of the theoretical and methodological foundations of collective health and the social determinants of health. The scope of this paper is to present theoretical contributions to the construction of a critical socio-environmental approach from a review of the literature structured around previous work on the mapping of environmental conflicts, and conducting empirical studies in conflicting areas. The contributions of sociology, political ecology, postcolonial studies and geography is summarized for the discussion of the socio-environmental determinants of health, as well as experiences that integrate emancipatory knowledge, political subjects, resistances and alternatives for society.
