BRITO, Ana Paula Nunes Pereira; RODRIGUES, Etria; VIANNA, Denise Loureiro  e  FERNANDES, Susi Mary de Souza. Investigation of postural edema in the lower extremities of traffic control workers. J. vasc. bras. [online]. 2013, vol.12, n.4, pp.289-295.  Epub 15-Dez-2013. ISSN 1677-5449.


Determine the prevalence of postural edema and investigate whether working posture - sitting down or standing up - affect its frequency.


Sixteen traffic control agents were assessed by water displacement volumetry and the results were analyzed in two groups, depending on working posture. Those who worked standing up for more than 4 hours were allocated to the SU group and those who worked sitting down for more than 4 hours were allocated to the SD group. Each worker was assessed before and after their working shift for three consecutive days. Data were analyzed using ANOVA and the test of equality of two proportions. The significance level was set at p ≤ 0.05. The assessment showed that members of both groups had postural edema of the lower extremities (p ≤ 0.001).


When the frequency of postural edema was compared across groups, a trend was observed for greater edema formation in the SU group than in the SD group, although without statistically significant difference.


It was concluded that traffic control agents suffer postural edema after 4 hours working in either of the postures investigated although with a predominance of edema formation among those who work standing up.
