Abstract:

Objective: to evaluate the pelvic floor muscles and the incidence of pelvic organ prolapse among indigenous women who live in Xingu Indian Park, Mato Grosso, Brazil.
Methods: observational study with 377 indigenous women, mean age 31+/-15 years, mean gravity 5+/-4, mean parity 4+/-3 and mean body mass index 23,3+/-4 Kg/m2. The Pelvic Organ Prolapse Quantification (POP-Q) was the system used to quantification the staging of pelvic support and the pelvic floor muscle strength was assessed by a perineometer. Logistic regression was used to determine odds ratios and 95% CI for factors that were associated with prolapse.
Results: The overall distribution of POP-Q stage system was the following: 15,6% stage 0, 19,4% stage I, 63,9% stage II and 0,8% stage III. Parity (OR=9.40, 95% CI 2.81-31,42) and age (OR=1,03, 95% IC 1,01-1,05) were the most important risk factors for pelvic organ prolapse. The high resting pressure was considered as a protecting factor (OR=0,96, 95% IC 0,94-0,98).
Conclusions: Like non indigenous community, age and the parity were the most important risk factors to the genital prolapse; however the pelvic floor muscles strength were intact, maybe due to the indigenous lifestyle.

Congratulations!!!! This is a great article and work.

Ao compararmos estes resultados com aqueles de nossas pacientes urbanas (não índias) e que exercem atividades físicas idênticas às indias não observamos os mesmos resultados. Será a homogeneidade étnica?

Maurício, obrigada pelo comentário. Respondendo a sua pergunta, gostaria de dizer que após os estudos genéticos do projeto Genoma foi determinado que a raça humana possui três linhagens genealógicas: ameríndias, européias e africanas. Em nosso estudo, embora não possamos afirmar com certeza que se trata de uma população homogenea de ameríndios (pois não fizemos estudo genético), tudo leva a crer que esta é a “linhagem genealógica” das mulheres do PIX. E neste sentido você está correto pois os estudos genéticos com DNA de brasileiros brancos feito pelo grupo do pesquisador da UFMG (Sérgio Danilo Pena) revela que a maioria das linhagens paternas da população branca do país veio da Europa, e 60% das linhagens maternas são ameríndias ou africanas. Entretanto, não podemos esquecer que no caso do prolapso genital outros fatores como idade e tipo de parto estão envolvidos.
