关键词：不健康生活方式
发表在《性医学期刊》（The Journal of Sexual Medicine）上的一篇最新研究发现，几种不健康的生活方式因素，如体重问题、体能活动不足、大量饮酒、吸烟以及吸食硬性毒品等与男性的性功能障碍有关。此外，不健康的生活方式更常见于性生活不活跃的人群中。
在丹麦“国家血清研究所（Statens Serum Institut）”Morten Frisch副教授（获得医学博士学位及理学博士学位）的带领下，利用2005年针对年龄在16岁到97岁之间的5552名丹麦男女进行的全国范围调查的数据，研究人员研究了生活方式因素与性行为不活跃和性功能障碍之间的联系。
研究结果发现，几种不健康的生活方式因素造成78%的男性和91%的女性增加了无性生活的风险。而有性伴侣的人群中，在生活方式不健康的男性中，腰围过粗的人经历性功能障碍的风险增加71%，服用硬性毒品的人经历性功能障碍的风险则增加800%。吸食大麻的女性发生性高潮障碍（在与伴侣进行性行为的时候难以或无法达到性高潮）的风险是不吸食大麻的女性的三倍。
“希望我们的研究结果在未来可以用来对生活方式不健康的病人进行心理辅导”，Frisch总结道。“了解不健康的生活方式可能对个人性健康产生的负面影响可以帮助人们戒烟、减少饮酒量、多参加锻炼以及减轻体重。”
“引起性功能障碍有很多原因，其中包括那些无法控制的因素，比如接受癌症治疗之后或受伤之后”，《性医学期刊》主编Irwin Goldstein解释道，“但是，生活方式和服用软性毒品是个人的选择。每个人都可以改变生活方式，特别是饮食和锻炼、停止服用抑制性反射的软性毒品，使身体更健康，从而促进性功能。”（生物谷Bioon.com）

Associations of Unhealthy Lifestyle Factors with Sexual Inactivity and Sexual Dysfunctions in Denmark
Aim.To examine associations between unhealthy lifestyle factors and sexual inactivity with a partner and four specific sexual dysfunctions in each sex.
Methods. We used nationally representative survey data from 5,552 Danish men and women aged 16–97 years in 2005. Cross-sectional associations of lifestyle factors with sexual inactivity and sexual dysfunctions were estimated by logistic regression-derived, confounder-adjusted odds ratios (ORs).
Main Outcome Measures. We calculated ORs for sexual inactivity with a partner and for sexual dysfunction and sexual difficulties overall in both sexes, for erectile dysfunction, anorgasmia, premature ejaculation, and dyspareunia in men, and for lubrication insufficiency, anorgasmia, dyspareunia, and vaginismus in women.
Results. Obesity (body mass index [BMI]≥30 kg/m2) or a substantially increased waist circumference (men ≥102 cm; women ≥88 cm), physical inactivity, and, among women, tobacco smoking were each significantly associated with sexual inactivity in the last year. Among sexually active men, both underweight (BMI <20 kg/m2) and obesity, a substantially increased waist circumference, physical inactivity in leisure time, high alcohol consumption (>21 alcoholic beverages/week), tobacco smoking, and use of hard drugs were each significantly positively associated with one or more sexual dysfunctions (ORs between 1.71 and 22.0). Among sexually active women, the only significant positive association between an unhealthy lifestyle factor and sexual dysfunction was between hashish use and anorgasmia (OR 2.85).
Conclusion.In both sexes, several unhealthy lifestyle factors were associated with sexual inactivity with a partner in the last year. Additionally, among sexually active participants, men with unhealthy lifestyles were significantly more likely to experience sexual dysfunctions. Considering the importance of a good sex life, our findings may be useful in attempts to promote healthier lifestyles.
