To examine how prevalence and context of sexual inactivity varies across the life-course, assess dissatisfaction with sex life among those who are sexually inactive and identify associations with factors that may represent reasons for sexual inactivity.
Analysis of cross-sectional probability sample survey data.
British general population.
14 623 participants (n men: 6045 unweighted, 7245 weighted), aged 16-74 years, of the third National Survey of Sexual Attitudes and Lifestyles (Natsal-3), undertaken in 2010-2012.
Sexual inactivity, defined as not reporting oral, vaginal or anal intercourse in the past year and further categorised into those who were sexually inexperienced (had never had sex), single or in a relationship.
Overall, 15.9% (weighted n 1155/7245) of men and 22.2% (1646/7410) of women were sexually inactive (p<0.001). The proportion of sexually inactive individuals who were sexually inexperienced was larger among men than women (26.3% (304/1155) vs 16.3% (268/1646)), while the proportion who were singles was larger among women (49.8% (820/1646) vs 40.4% (467/1155)). Sexual inexperience was the most common type of sexual inactivity in early adulthood, with this declining with age. A minority of those who had sexual experience but were sexually inactive-34.8% (293/842) of men and 23.6% (319/1349) of women-reported being dissatisfied with their sex lives. Associations with sexual inactivity was observed for a range of sociodemographics and sexual behaviours/attitudes, for example, religion, ethnicity, Body mass index, height, employment status and index of multiple deprivation; these associations varied by type of sexual inactivity and gender.
While sex is important for well-being, a non-negligible proportion of the population at all ages are sexually inactive, yet many are not dissatisfied with their situation, with implications for sex and relationship counselling.
研究性不活跃在整个生命周期中的流行程度和情况如何变化，评估那些性不活跃的人的性生活满意度，并确定与可能代表性不活跃原因的因素之间的关联。
横断面概率抽样调查数据的分析。
英国普通人群。
14623 名参与者（n 男性：6045 未加权，7245 加权），年龄在 16-74 岁之间，参加了 2010-2012 年进行的第三次全国性态度和生活方式调查（Natsal-3）。
性不活跃，定义为在过去一年中没有报告口交、阴道交或肛交，进一步分为性经验不足（从未有过性行为）、单身或处于恋爱关系的人群。
总体而言，15.9%（加权 n=7245 中的 1155 人）的男性和 22.2%（7410 中的 1646 人）的女性为性不活跃（p<0.001）。性不活跃的个体中，性经验不足的比例在男性中高于女性（26.3%（304/1155）与 16.3%（268/1646）），而单身的比例在女性中更高（49.8%（820/1646）与 40.4%（467/1155））。性经验不足是青年早期最常见的性不活跃类型，随着年龄的增长，这种情况会下降。少数有性经验但性不活跃的人-34.8%（293/842）的男性和 23.6%（319/1349）的女性-报告对他们的性生活不满意。与性不活跃相关的因素包括一系列社会人口统计学和性行为/态度因素，例如宗教、种族、体重指数、身高、就业状况和多重剥夺指数；这些关联因性不活跃的类型和性别而异。
尽管性对幸福感很重要，但相当一部分不同年龄段的人都处于性不活跃状态，但许多人对自己的状况并不感到不满，这对性和关系咨询有影响。
