Climacteric symptoms in Quechua and Mestizo women from the Andean region of Cusco, Peru: effects of altitude and ethnicity.

Background: Latin-American women present a greater severity of climacteric symptoms than women from other parts of the world. Previous studies suggest that this could be due to either its Amerindian crossbreeding or the altitude in which a huge proportion of the Latin-American population lives.

Objective: To answer this question, climacteric symptoms between Peruvian women ("Hispanic-Mestizas" and "Quechuas") living in similar altitude (around 3000 MASL) were compared.

[Official position of the Chilean Society of Climacteric on the management of climacteric women].

The health of many women is affected in the climacteric period, either by symptoms that deteriorate their life quality (QL) or by chronic diseases that affect their life expectancy. Therefore, it is mandatory to evaluate these two aspects, having as core objectives for any eventual therapeutic intervention, the improvement of QL and the reduction of cardiovascular risk and fractures. To evaluate QL it is mandatory to follow structured interviews that weigh systematically climacteric symptoms such as the Menopause Rating Scale (MRS).
