The aim of this study was to investigate the influence of biomedical indicators, such as body mass index, blood glucose, total cholesterol, triglycerides, systolic blood pressure and diastolic blood pressure, on sexual functioning in Portuguese adults.
The sample consisted of 225 healthy individuals (non-smokers, women not taking contraceptive pill), aged 18-89 years (mean = 41 years), of whom 107 were males and 117 females. A Sociodemographic Questionnaire, the Portuguese version of the Massachusetts General Hospital Sexual Functioning Questionnaire (MGH-SFQ) and biomedical indicators measurement devices were applied.
59.6% (N = 134) of the participants presented levels for global sexual functioning below the expected values. Men scored better overall sexual functioning when compared to women, as well as the group of younger participants. Significant correlational values between BMI (r = -253, p <.001), glycemic index (r = -.230, p <.001), total cholesterol (r = -144, p < .05) and sexual functioning were obtained. The hierarchical regression model allowed to demonstrate the mediating effect of the biomedical variables on sexual functioning, explaining 31% (r2 = .31; p <.001) of the total variance.
This research makes it possible to highlight the importance of biomedical indicators in sexual functioning, helping professionals working in this area to be aware of how biomedical contexts interfere with sexual expression.
本研究旨在调查体重指数、血糖、总胆固醇、甘油三酯、收缩压和舒张压等生物医学指标对葡萄牙成年人性功能的影响。
样本包括225名健康个体（不吸烟者，未服用避孕药的女性），年龄在18 - 89岁之间（平均 = 41岁），其中男性107名，女性117名。应用了一份社会人口学问卷、葡萄牙语版的马萨诸塞州综合医院性功能问卷（MGH - SFQ）以及生物医学指标测量设备。
59.6%（N = 134）的参与者的总体性功能水平低于预期值。与女性以及年轻参与者组相比，男性在总体性功能方面得分更高。体重指数（r = - 0.253，p <.001）、血糖指数（r = - 0.230，p <.001）、总胆固醇（r = - 0.144，p <.05）与性功能之间存在显著的相关性。分层回归模型能够证明生物医学变量对性功能的中介作用，解释了总方差的31%（r² =.31；p <.001）。
本研究能够突出生物医学指标在性功能中的重要性，帮助该领域的专业人员了解生物医学背景如何干扰性表达。
