This study aimed to comparatively evaluate the presence of abnormal uterine bleeding and associated factors among women from the five official Brazilian geographic regions.
This is a cross-sectional, population-based, multicenter study of reproductive-age women from the five regions of Brazil. All participants answered questionnaires containing personal and socioeconomic data and information on uterine bleeding (self-perception and objective data).
A total of 1,761 Brazilian women were included, 724 from the Southeast, 408 from the Northeast, 221 from the South, 213 from the North, and 195 from the Central-West. Considering women's self-perception, the prevalence of abnormal uterine bleeding was 37.56% in the North region, 39.46% in the Northeast, 21.54% in the Central-West, 29.56% in the Southeast, and 25.34% in the South (p<0.001). Abnormal uterine bleeding was more prevalent in the North and Northeast, where women had lower purchasing power, became pregnant more often, and were the only ones financially responsible for supporting the family more often (p<0.001). The menstrual cycle lasted <24 days in less than 20% of the women in all regions (p=NS). Among these, approximately 8 out of 10 women had never undergone treatment in four out of the five regions evaluated. More than half of the evaluated women reported a worsening of their quality of life during bleeding.
The prevalence of abnormal uterine bleeding in Brazilian women was higher in the North and Northeast, followed by the Southeast, South, and Central-West regions. There was a worsening of quality of life during menstruation regardless of the woman's self-perception of abnormal uterine bleeding. Such results can direct the actions of health managers toward a better approach to abnormal bleeding.
本研究旨在比较评估巴西五个官方地区女性异常子宫出血的发生情况及其相关因素。
这是一项多中心、基于人群的横断面研究，研究对象为来自巴西五个地区的育龄期女性。所有参与者均回答了包含个人和社会经济数据以及子宫出血（自我感知和客观数据）信息的问卷。
共纳入 1761 名巴西女性，其中 724 名来自东南部、408 名来自东北部、221 名来自南部、213 名来自北部和 195 名来自中西部。考虑到女性的自我感知，北地区异常子宫出血的患病率为 37.56%，东北部为 39.46%，中西部为 21.54%，东南部为 29.56%，南部为 25.34%（p<0.001）。北地区和东北部的异常子宫出血更为常见，这些地区的女性购买力较低，怀孕频率较高，且更常独自承担家庭经济责任（p<0.001）。所有地区的女性中，不到 20%的人月经周期持续时间<24 天（p=NS）。在这些人中，约有 8/10 的人在评估的五个地区中的四个地区从未接受过治疗。超过一半的受评估女性在出血期间报告生活质量恶化。
巴西女性异常子宫出血的患病率在北部和东北部较高，其次是东南部、南部和中西部。无论女性是否自我感知到异常子宫出血，月经期间的生活质量都会恶化。这些结果可以指导卫生管理者采取更好的方法来处理异常出血。
