The female body suffers from standards imposed by society determined by the media or social networks, generating a continuous desire for bodies incompatible with reality. This desire can generate low self-esteem, causing women to feel dissatisfied with their own appearance. This is an important factor in sexual satisfaction, because women dissatisfied with their body and appearance may be ashamed to expose it to their partners, making sexual intercourse uncomfortable. It is necessary to understand the existing relationship between body and sexual dissatisfaction due to the scarcity of studies, assisting in the care of the health of the woman.

The objective of this study was to verify the relationship between body and sexual satisfaction of women assisted in a Basic Health Unit (BHU).

Epidemiological, observational, cross-sectional study, conducted in a UBS in the city of Guarapuava - PR, with women enrolled in the Women's Comprehensive Health Program. Inclusion criteria were women aged 18 to 59 years who agreed to the Informed Consent Form. In September 2021, 1,811 women were enrolled in the Comprehensive Women's Health program, and the sample calculation with the StatCalc application of the Epi Info 7.2.4 program totaled 326 eligible women. Data collection was performed by applying a questionnaire during the period from October 02, 2021 to February 15, 2022, containing: sample characterization; lifestyle; women's health; sexual performance; body satisfaction. The dependent variable was sexual dissatisfaction, by the questionnaire Sexual Quotient - Female Version (QS-F), validated by Abdo, (2009). The independent variable was body image, collected by the Stunkard Silhouettes Scale, validated by Scagliusi, (2006). Data analysis was performed using the Statistical Package for the Social Sciences - IBM SPSS Statistic v.19 for Windows®. The association analysis between variables was performed using Pearson's Chi-square and ANOVA tests (statistical significance 5%, p-value<0.05). The reference category of the independent variable "body image" was the response "satisfied".

Among the 326 women eligible for the study, there were 269 in this study, considering the losses and refusals. The mean age was 33.52 ± 10.15, mostly white (74.0%), with a partner (74.3%), working (63.8%), with children (79.0%), sexually satisfied (79.5%) and dissatisfied with their bodies (81.8%). Of these women, 20.6% were sexually dissatisfied. Statistical association was found between sexual dissatisfaction and mean age (<0.05), children (<0.001), menopause (<0.001), and body dissatisfaction (<0.05). There was a higher prevalence of sexual dissatisfaction in women dissatisfied with their bodies.

It was possible to conclude that there is a relationship between body image and sexual dissatisfaction in women who are assisted in a UBS.

These findings may help in the planning of actions to women's health in the Primary Care setting.
