Physical activity overcomes the effects of cumulative work time on hypertension prevalence among Brazilian taxi drivers
Vieira, MC, Sperandei, S & Reis, AC in press, 'Physical activity overcomes the effects of cumulative work time on hypertension prevalence among Brazilian taxi drivers', The Journal of Sports Medicine and Physical Fitness, vol. 56, no. 5, pp. 631-638.
AIM: The aim of this study was to assess the physical activity profile of taxi drivers and its relationship with hypertension prevalence in this group of workers.
METHODS: Cross sectional exploratory study. Between November 2008 and April 2009, 491 taxi drivers from Rio de Janeiro, Brazil, answered a questionnaire focusing on previous hypertension diagnosis, occupational characteristics and physical activity habits. Two logistic models were developed to determine risk factors related to hypertension and to find variables associated with a higher probability of sedentarism.
RESULTS: Hypertension prevalence was 22.6%. The workload of the group investigated was high. Results indicate that 'age', 'body mass index', 'physical activity', and 'years as a taxi driver' are related to the probability of hypertension. Physical activity was shown to be a protection factor for hypertension, even considering the deleterious effect of time as a taxi driver. Our results also determined that the practice of physical activity is influenced by age, level of education and workload.
CONCLUSIONS: It is recommended that programs to combat sedentary lifestyles as well as measures to reduce workloads be developed as strategies to prevent hypertension.
