Pelvic floor muscle strength and body self-perception among Brazilian pregnant women

ObjectivesTo examine the relationship between pelvic floor muscle strength and body self-perception variables in pregnant women; and, more specifically, to determine the influence of the number of pregnancies (primigravidas vs multigravidas) on the strength of contraction of the pelvic floor muscles and on the body self-perception of pregnant women.DesignComparative cross-sectional research.SettingPublic health centres from Florianópolis, Brazil.ParticipantsThirty-five pregnant women (18 primigravidas, 17 multigravidas) with a mean age of 25.5 (standard deviation 5.7) years.Main outcome measuresPelvic floor strength measured through manual palpation, and body self-perception using the Questionnaire of Corporeality and Human Sexuality.ResultsPelvic floor muscle strength was positively correlated with schooling [rho (ρ) = 0.496] and body self-perception variables: finding the body beautiful (ρ = 0.476), finding the body sexy (ρ = 0.520), feeling that others find them sexy (ρ = 0.364), finding the body proportional (ρ = 0.412), touching the body generally (ρ = 0.554) and recognising the smell of the body (ρ = 0.454). Primigravidas found their bodies more beautiful and were more satisfied with their bodies. On a scale of 0 to 6, multigravid participants expressed a greater wish than primigravid participants to be thinner (median difference 2, 95% confidence interval 0–3, P = 0.03). Pelvic floor strength did not differ between groups.ConclusionsThe results suggest a relationship between pelvic floor muscle strength and body self-perception. Professionals involved in women's health may have a role in helping their patients to understand their bodies.
