BRUTTO, Oscar H. Del; MERA, Robertino M.; ZAMBRANO, Mauricio  e  CASTILLO, Pablo. Sleep disorders in Atahualpa residents. Rev Ecuat Neurol [online]. 2017, vol.26, n.2, pp.135-150. ISSN 2631-2581.

Health problems related to sleep disorders are likely on the rise in rural areas of Latin America, partly related to changes in life style, shift work, and other factors. However, little is known on the burden of these conditions in remote rural settings. In the Atahualpa Project, we have investigated sleep disorders using standardized field instruments associated with sophisticated technology such as polysomnography. A poor sleep quality has been associated with frailty and with the presence of neuroimaging markers of cerebral small vessel disease and global cortical atrophy. On the contrary, dietary intake of oily fish was associated with a better sleep quality. We have also investigated the prevalence and some correlates of the restless legs syndrome (Willis-Ekbom disease), and found a prevalence relatively higher than that described in most other tropical regions, as well as the association of this condition with psychological stress. Finally, a preliminary report shows a high prevalence of moderate-to-severe obstructive sleep apnea in Atahualpa residents aged ≥60 years (27%) and its correlation with diffuse subcortical damage of vascular origin. Further studies are needed to better understand consequences of sleep-related symptoms in underserved populations.
