Female sexual function depends on biological, psychological, and sociocultural contexts.
The objective of the present study was to evaluate the prevalence of low levels of functioning in each of the sexual function domains (desire, arousal, and orgasm) and the factors associated with these phenomena, as well as to assess the frequency of sexual activity in this same sample population.
A cross-sectional, population-based study was conducted using an anonymous self-response questionnaire completed by 378 Brazilian-born women of 40-65 years of age with 11 years or more of formal education. The evaluation instrument was based on the Short Personal Experiences Questionnaire.
The prevalence of low sexual desire was 60.6%; low arousal, 37%; and low orgasmic function, 31.1%. Multiple regression analysis showed that having a sexual partner (prevalence ratio [PR] = 0.69, confidence interval [CI] = 0.53-0.90) and nervousness (PR = 1.33, CI = 1.01-1.75) were factors associated with low sexual desire. Aging (PR = 1.04, CI = 1.02-1.06), having a sexual partner (PR = 0.57, CI = 0.41-0.81), feeling well/excellent (PR = 0.59, CI = 0.41-0.85), and having hot flashes (PR = 1.47, CI = 1.01 = 2.15) were factors found to be associated with low sexual arousal. Having a sexual partner (PR = 0.55, CI = 0.42-0.71), feeling well/excellent (PR = 0.68, CI = 0.49-0.94), and having hot flashes (PR = 2.08, CI = 1.43 = 3.04) were factors found to be associated with low sexual orgasmic function. Having a sexual partner (PR = 0.47, CI = 0.38-0.58), feeling well/excellent (PR = 0.78, CI = 0.69-0.89), and having hot flashes (PR = 1.15, CI = 1.05-1.26) were factors found to be associated with a frequency of sexual activity of once a week or less.
In this sample of middle-aged women, low sexual desire was the most prevalent sexual problem. These results highlight the importance of identifying and treating factors associated with each individual component of low female sexual function.
女性的性功能取决于生物、心理和社会文化等多个方面。
本研究旨在评估每个性功能领域（性欲、唤起和高潮）的功能低下发生率，以及与这些现象相关的因素，同时评估该人群的性行为频率。
采用基于短个人体验问卷的匿名自我应答式问卷调查，对 378 名年龄在 40-65 岁之间、接受过 11 年及以上正规教育的巴西出生的女性进行了横断面、基于人群的研究。
性欲低下的发生率为 60.6%；唤起低下发生率为 37%；性高潮功能低下发生率为 31.1%。多因素回归分析显示，有性伴侣（比值比[PR] = 0.69，95%置信区间[CI] = 0.53-0.90）和紧张（PR = 1.33，CI = 1.01-1.75）是性欲低下的相关因素。年龄增长（PR = 1.04，CI = 1.02-1.06）、有性伴侣（PR = 0.57，CI = 0.41-0.81）、感觉良好/非常好（PR = 0.59，CI = 0.41-0.85）和出现热潮（PR = 1.47，CI = 1.01-2.15）是与唤起低下相关的因素。有性伴侣（PR = 0.55，CI = 0.42-0.71）、感觉良好/非常好（PR = 0.68，CI = 0.49-0.94）和出现热潮（PR = 2.08，CI = 1.43-3.04）是与性高潮功能低下相关的因素。有性伴侣（PR = 0.47，CI = 0.38-0.58）、感觉良好/非常好（PR = 0.78，CI = 0.69-0.89）和出现热潮（PR = 1.15，CI = 1.05-1.26）是与每周一次性行为或更少相关的因素。
在本项针对中年女性的样本研究中，性欲低下是最常见的性功能问题。这些结果强调了识别和治疗与女性性功能各组成部分相关因素的重要性。
