Objective: To translate the Menopause Perception Scale (MPS) into Chinese, and evaluate the reliability and validity of the Chinese version of the MPS. Methods: The MPS was translated back-translated, culturally adapted and pre-tested according to the Brislin translation model to develop the Chinese version of MPS. The menopausal women from five communities were selected using simple random sampling to assess the reliability and validity of the Chinese version of MPS. Content validity was evaluated based on expert ratings, criterion-related validity was evaluated using the Chinese version of the Menopause Rating Scale (MRS) as the criterion. Structural validity was evaluated using exploratory factor analysis and confirmatory factor analysis. Internal consistency was evaluated using Cronbach's α, and split-half reliability and test-retest reliability were calculated. Results: Totally 430 questionnaires were allocated, and 414 valid questionnaires were recovered, with an effective recovery rate of 96.28%. The Chinese version of the MPS consisted of 18 items across four dimensions: acceptance, sexual perception, normalization, and support perception. The item-level content validity index ranged from 0.833 to 1.000, and the scale-level content validity index average was 0.924. The correlation coefficients between the scores of each dimension and the total scores of the Chinese version of the MPS and the Chinese version of the MRS ranged from 0.529 to 0.790 (all P<0.05). Exploratory factor analysis extracted four common factors, with a cumulative variance contribution rate of 64.502%. Confirmatory factor analysis showed good model fit, with a root mean square error of approximation of 0.052, root mean square residual of 0.053, comparative fit index of 0.958, Tucker-Lewis index of 0.950, goodness of fit index of 0.908, incremental fit index of 0.958, and relative fit index of 0.884. The Cronbach's α of the Chinese version of the MPS was 0.916, the split-half reliability coefficient was 0.845, and the test-retest reliability was 0.906. Conclusion The Chinese version of the MPS demonstrates good reliability and validity, and can be used to assess the perceptions and attitudes of menopausal women in China toward menopause.

Background::Understanding the characteristics of newly diagnosed primary human deficiency virus-1 (HIV-1) infection in the context of the post-antiretroviral therapy era and HIV drug prophylaxis is essential for achieving the new target of 95-95-95-95 by 2025. This study reported the characteristics of newly diagnosed primary HIV-1 infection in Shenzhen.Methods::This is a real-world retrospective study. Eighty-seven newly diagnosed primary HIV-1-infected patients were recruited from January 2021 to March 2022 at the Third People’s Hospital of Shenzhen. Demographic, epidemiological, diagnostic, drug resistance, and medical data were described and analyzed.Results::Overall, 96.6% (84/87) of the newly identified primary HIV-1-infected patients were male, including 88.5% (77/87) men have sex with men (MSM), with a median age of 29.0 years (Q 1-Q 3: 24.0-34.0 years); of these, 85.1% (74/87) reported high-risk sexual behaviors with casual partners. The rate of condom usage was only 28.7% (25/87). The overall rate of pre-exposure prophylaxis (PrEP) and post-exposure prophylaxis (PEP) was 8.0% (7/87, including 4 PrEP and 3 PEP cases) around the potential exposure, although 41.4% of the patients had prior awareness of such interventions. Moreover, only 19.5% (17/87) had previously used PrEP or PEP. Of those, 58.8% (10/17) of the patients obtained drugs from the internet, and only 35.3% (6/17) reported good compliance. A total of 54.0% (47/87) of subjects were diagnosed by the HIV nucleic acid test. Acute retroviral syndrome appeared in 54.0% (47/87) of patients. The prevalence of transmitted drug resistance (TDR) mutation was 33.9% (19/56), including 6 (10.7%) against nucleoside reverse transcriptase inhibitor (NRTI) plus non-nucleoside reverse transcriptase inhibitor (NNRTI), 8 (14.3%) against NNRTI, and 5 (8.9%) against protease inhibitor (PI) only. Conclusions::Owing to the low utilization rate and incorrect usage of PrEP and PEP, massive efforts are needed to promote HIV-preventive strategies in the MSM population. The extremely high prevalence of TDR mutation in this population implies the need for future pretreatment drug resistance surveillance.
