Abstract

Objective: To obtain comparative indices between countries, related to the real situation of the pregnant woman -used resources and obtained results- in the Region of the Americas. Material and Methods: We compiled information on the countries of the Region of the Américas, published by WHO and PAHO, corresponding to variables related directly to the pregnant woman and potential resources used in her clinical attention, in addition to the obtained results from this attention. The last complete and official available information is used. Nine variables were studied: total fertility rate, birth rate, maternal mortality ratio, prevalence of use of contraceptive methods, pregnant population proportion taken care of by trained personnel during pregnancy, deliveries assisted by trained personnel, national health cost per person per year and as a proportion of the BIP and health public cost as a proportion of the national health cost. The principal components analysis technique was applied, and the correlation matrix R was used. Results: The two first principal components were selected, with an accumulated percentage of explained variability of 67.31%. Conclusions: The first component relates to the prevalence of use of contraceptive methods and the proportion of pregnant population whose deliveries are assisted by trained personnel. An inverse relation of the first component with the total fertility rate, birth rate and maternal mortality ratio exists. This first component would lead us to the positive results that offer suitable services strategies that privilege responsible paternity. The second principal component is related to the national health cost as a proportion from BIP and inversely with the public health cost per year as a proportion from national health cost.
