Evaluation of temporal changes in the sexual function among Japanese women using the female sexual function index: An Internet survey.

ABSTRACT:

Objectives

Female sexual dysfunction is an underestimated problem that negatively affects women's quality of life. Although the overall prevalence of sexual dysfunction in women is high, only a few studies have focused on this problem. In Japan, an index of female sexual function has not been clearly defined. Hence, this study aimed to investigate the sexual function of normal Japanese women and the temporal changes they experienced using the Female Sexual Function Index administered online in 2012 and 2019.

Methods

The subjects were Japanese women aged 20-79 years registered in an Internet research company. We collected data of 1034 and 2031 women in 2012 and 2019, respectively, based on Japan's population distribution according to age. Subsequently, we analyzed the collected data using a Japanese version of the Female Sexual Function Index. We investigated the temporal changes in the Female Sexual Function Index total score, the ratio of women who did not engage in sexual activities and women having "no sexual activity" with their partners, and the total Female Sexual Function Index scores according to age.

Results

The average Female Sexual Function Index total score decreased from 14.6 in 2012 to 12.5 in 2019 (p < 0.001). No significant difference was observed in the average Female Sexual Function Index score of the group with sexual activity between 2012 (22.2) and 2019 (22.4). The ratio of women not engaging in sexual activities increased from 42.2% in 2012 to 54.0% in 2019. The ratio of women having "no sexual activity" with their partners increased by 10%.

Conclusion

Comparison of data between 2012 and 2019 indicated that Japanese women have become less sexually active. The average Female Sexual Function Index total score of 22 may be useful as a reference value for diagnosing female sexual dysfunction in Japan.

Project description:IntroductionCannabis use has increased in the last decade, and the impact of cannabis on female sexual function remains unclear.AimTo assess the impact of frequency of use, chemovar (tetrahydrocannabinol, cannabinol, or both) type, and method of consumption on female sexual function among cannabis users.MethodsAdults who visited a single-partner cannabis dispensary's locations were invited to participate in an uncompensated, anonymous online survey October 20, 2019 and March 12, 2020. The survey assessed baseline demographics, health status, cannabis use habits as well as used the validated Female Sexual Function Index (FSFI) to assess sexual function.Main outcome measureThe main outcomes of this study are the total FSFI score (sexual dysfunction cutoff <26.55) and subdomain scores including desire, arousal, lubrication, orgasm, satisfaction, and pain.ResultsA total of 452 women responded with the majority between the ages of 30-49 years (54.7%) and in a relationship or married (81.6%). Of them,72.8% reported using cannabis more than 6 times per week, usually through smoking flower (46.7%). Women who reported more cannabis use, reported higher FSFI scores (29.0 vs 26.7 for lowest vs highest frequencies of reported use, P = .003). Moreover, an increase in cannabis use frequency by one additional use per week was associated with an increase in total FSFI (β = 0.61, P = .0004) and subdomains including desire domain (P = .02), arousal domain (P = .0002), orgasm domain (P = .002), and satisfaction domain (P = .003). For each additional step of cannabis use intensity (ie, times per week), the odds of reporting female sexual dysfunction declined by 21% (odds ratio: 0.79, 95% confidence interval: 0.68-0.92, P = .002). Method of consumption of cannabis and chemovar type did not consistently impact FSFI scores or odds of sexual dysfunction.ConclusionIncreased frequency of marijuana use is associated with improved sexual function among female users, whereas chemovar type, method of consumption, and reason for use does not impact outcomes.

Project description:The prevalence of cervical cancer among women aged 20-30 years has been increasing. A better understanding of the factors correlated with cervical cancer screening is vital to better identify suitable candidates and develop effective interventions. However, few studies have examined factors correlated with cervical cancer screening using a quantitative research design. Thus, this study aimed to assess the prevalence of and factors correlated with cervical cancer screening among unmarried and sexually active Japanese women aged 20-29 years.Seven hundred Japanese women who responded to an internet-based cross-sectional survey conducted by a marketing research company in 2015 were enrolled. Associations between lifetime cervical cancer screening and demographic profile, sexual behavior, and psychosocial factors were assessed via univariate analysis. Variables indicating significance (P?<?0.05) were used in the univariate analysis to determine adjusted odds ratios (AOR).Overall, 383 (54.7%) respondents underwent cervical cancer screening during their lifetime. Multiple regression analysis indicated that age, employment status, income, lifetime number of sex partners, human papillomavirus (HPV) vaccination, receipt of a free coupon for cervical cancer screening from the local government, perceived susceptibility and logistical barriers (cost/time), and confidence of receiving Pap testing from a male physician were significantly correlated with lifetime cervical cancer screening. Individuals aged 28-29 years (AOR?=?1.86) and those with full-time employment (AOR?=?3.30), income ? ¥ 4,000,000($35,000) (AOR?=?1.60), >?5 lifetime sex partners (AOR?=?1.97), HPV vaccination (AOR?=?4.88), coupon from the local government (AOR?=?3.14), higher perceived level of cervical cancer susceptibility (middle, AOR?=?1.77; high, AOR?=?3.23), lower perceived logistical barriers (middle, AOR?=?0.55; high, AOR?=?0.31), and higher confidence of receiving pap testing from a male physician (AOR?=?2.66) were more likely to undergo cervical cancer screening.Women who were younger and unemployed and those with lower perceived cervical cancer susceptibility, higher perceived logistical barriers, and lower confidence of receiving Pap testing from a male physician were less likely to undergo lifetime cervical cancer screening. Thus, to increase the cervical cancer screening rate among young women, it may be effective to target younger unemployed women, provide interventions to increase perceived susceptibility, and recommend tests while considering psychosocial barriers.

Project description:IntroductionFemale sexual dysfunction (FSD) is a common problem, and many self-report questionnaires are available for its evaluation. Pakistani women with sexual problems feel shy to consult with their physician. A validated self-report questionnaire, in the local language with modest expressions is required for these women.AimThe aim of this study was to translate, cross-culturally adapt, and perform a psychometric validation of an Urdu translation of the Female Sexual Function Index (FSFI).MethodsThe FSFI was translated in Urdu, and its precision was ascertained through reverse translation. It was pretested on 22 bilingual women and refined again to reach at a reliable Urdu version of the questionnaire FSFI-U. One hundred sixteen bilingual women, in a stable sexual relationship over the previous 6 months were finally asked to fill out the FSFI and FSFI-U. Their sexual function was then clinically evaluated and responses were compared with the clinical assessment as well as with each other.Main outcome measuresThe responses were analyzed through descriptive statistics for reliability, face validity, agreement between the responses to the original English version and to the FSFI-U, and also for test-retest consistency. The data were analyzed statistically using Cronbach's alpha analysis, Intraclass correlation coefficients, Pearson correlation, and Student's t-test.ResultsFSFI was found to be easily understandable and capable of adequately evaluating and measuring various aspects of female sexual function. A high degree of internal consistency was demonstrated on Cronbach's alpha analysis. Cronbach's ? coefficient for various domains was sufficiently high ranging from 0.84 to 0.97. The clinical assessment of the presence and severity of FSD also matched with the self-report questionnaire. Similarly, various domains of FSFI had high degree of correlation in the Urdu version of FSFI (P?<?0.001).ConclusionThe Urdu translation version of FSFI is valid and reliable for use in the literate population of Pakistan.
