Abstract

OBJECTIVE

To assess sexual activity, sexual function, and their correlation with vaginal maturation status among middle-aged Chinese women.

METHODS

A cross-sectional study with comparisons across age groups was carried out. In all, 120 women aged 45 to 60 years were recruited into three groups: 45 to 50 (youngest group), 51 to 55 (intermediate group), and 56 to 60 years old (eldest group). Sexual function was assessed through the Female Sexual Function Index (FSFI); vaginal maturation status was determined through the Vaginal Maturation Index (VMI) and pH value. Sexual activity was recorded with self-administered questionnaires.

RESULTS

Low sexual frequency was present in a higher proportion of women, but sexual distress was identified within a lower proportion of women in the eldest group. The total FSFI score was significantly lower in the eldest group than in the youngest and intermediate groups (P < 0.01 and 0.05, respectively); however, the domain score of sexual desire, arousal, and satisfaction was lower in the eldest group than in the youngest group (P < 0.01, 0.05, and 0.05) only. The domain score for lubrication was lower in the eldest group than in both the youngest and intermediate groups (P < 0.01 and 0.05), and the pain score was lower in both the intermediate and eldest groups than in the youngest group (P < 0.01 and 0.05). A lower VMI (P < 0.001) and a higher pH value (P < 0.01) were observed in the eldest group, compared with the youngest group. Moreover, VMI was positively correlated with the total FSFI score, the domain score for sexual desire, and lubrication (r = 0.26, 0.25, 0.34; P < 0.05, 0.05, 0.01), but the opposite associations were demonstrated for pH value (r = -0.47, -0.37, -0.38; P < 0.01, respectively), especially with vaginal pain (r = -0.44, P < 0.01).

CONCLUSIONS

Among middle-aged Chinese women, sexual desire is lower in 56 to 60-year-old women, compared with those aged 45 to 55 years, whereas vaginal dryness and dyspareunia become more prevalent with age. Importantly, sexual function is associated with vaginal maturation status in women at midlife.

摘要

目的

评估中国中年女性的性活动、性功能及其与阴道成熟状态的相关性。

方法

开展一项进行年龄组间比较的横断面研究。共招募了120名45至60岁的女性，分为三组：45至50岁（最年轻组）、51至55岁（中间组）和56至60岁（最年长组）。通过女性性功能指数（FSFI）评估性功能；通过阴道成熟指数（VMI）和pH值确定阴道成熟状态。通过自行填写问卷记录性活动情况。

结果

较高比例的女性存在低性频率，但最年长组中存在性困扰的女性比例较低。最年长组的FSFI总分显著低于最年轻组和中间组（分别为P<0.01和0.05）；然而，仅在最年长组中，性欲、性唤起和性满意度的领域得分低于最年轻组（分别为P<0.01、0.05和0.05）。最年长组的润滑领域得分低于最年轻组和中间组（分别为P<0.01和0.05），中间组和最年长组的疼痛得分均低于最年轻组（分别为P<0.01和0.05）。与最年轻组相比，最年长组的VMI较低（P<0.001），pH值较高（P<0.01）。此外，VMI与FSFI总分、性欲领域得分和润滑呈正相关（r=0.26、0.25、0.34；P<0.05、0.05、0.01），但pH值与之呈相反的关联（r=-0.47、-0.37、-0.38；P均<0.01），尤其是与阴道疼痛的关联（r=-0.44，P<0.01）。
