An analysis of the main reasons that perimenopausal and postmenopausal women in China have for seeking outpatient treatment and factors influencing their symptoms: a single-center survey

Prevalence of menopausal symptoms and attitudes towards menopausal hormone therapy in women aged 40-60 years: a cross-sectional study

BACKGROUND

Menopause is a specific physical and psychological transition period for women, during which they experience a series of menopausal symptoms. Menopausal hormone therapy is an important treatment for improving menopausal symptoms. Helping women correctly understand menopausal hormone therapy is a prerequisite for increasing the acceptance and utilization of menopausal hormone therapy by women. Physical examinations are an important method for women to master their own health status and detect potential health problems, and in recent years, an increasing number of women have actively participated in physical examinations. Therefore, this study aims to comprehend the prevalence of menopausal symptoms and attitudes towards menopausal hormone therapy among women aged 40-60 who underwent physical examinations, which would provide a useful reference to reduce the prevalence of menopausal symptoms and improve acceptance of menopausal hormone therapy.

METHODS

This cross-sectional study was conducted at the Health Management Centre of the Affiliated Hospital of Southwest Medical University in Luzhou City, Sichuan Province. The data were collected from 295 women aged between 40 and 60 using convenience sampling. Information on all participants was collected through face-to-face interviews. Participants completed a demographic questionnaire and an attitude towards menopausal hormone therapy questionnaire, and the modified Kupperman index was used to assess the prevalence and severity of participants' menopausal symptoms. The collected data were processed using SPSS and Excel software and analysed using descriptive statistics and logistic regression.

RESULTS

The top 5 menopausal symptoms were insomnia, fatigue, bone and joint pain, sexual dysfunction and emotional instability. Multiple linear regression analysis showed that residence, sexual intercourse frequency, mentality, and physical exercise were the influencing factors of menopausal symptoms. The study showed that 77% of women said they were still reluctant to receive menopausal hormone therapy after experiencing menopause-related symptoms. The main source of menopausal hormone therapy-related knowledge among women was from surrounding menopausal women (62%), and 54% wanted to gain menopausal hormone therapy-related knowledge through a web-based approach.

CONCLUSION

The incidence of menopausal symptoms is higher in women aged 40-60 years, which is related to women's mentality, exercise, and sexual intercourse frequency. In addition, the results of this study indicate that women's knowledge of menopausal hormone therapy is insufficient, which suggests that we need to strengthen health education to improve the acceptance rate of menopausal hormone therapy.

Signal characteristics of normal adult bone marrow in whole-body diffusion-weighted imaging

BACKGROUND

Knowledge of the signal characteristics of normal adult bone marrow in whole-body diffusion-weighted (DW) images (WB-DWI) is essential for correctly interpreting DW images in clinical practice; however, these factors have not yet been clearly determined.

PURPOSE

To evaluate the signal characteristics of normal adult bone marrow in WB-DWI, to correlate these characteristics with age and gender, and to determine the causes of these phenomena.

MATERIAL AND METHODS

Ninety-eight healthy volunteers underwent WB-DWI (b = 0 and 800 s/mm(2)). Two radiologists visually evaluated the signal characteristics of bone marrow in DW images separately. One radiologist measured the apparent diffusion coefficient (ADC) of the thoracic and lumbar vertebrae, bilateral femur (including head, neck, and proximal and distal femoral shaft), bilateral humeral head, ilium, and scapula. The signal characteristics of normal bone marrow were analyzed.

RESULTS

The visual evaluation results of DW images indicated that hyperintensity of bone marrow was more frequently seen in women aged 21-50 years (68.4%) than in men aged 21-50 years (3.3%) (P < 0.001), men aged 51-81 years (5.9%) (P < 0.001), and women aged 51-81 years (15.4%) (P = 0.001). However, no statistically significant difference was found between men and women aged 51-81 years (P = 0.565). The ADC of bone marrow was significantly higher in women than in men aged 21-50 years. Bone marrow ADC showed significant negative correlation with age in women but not in men.

CONCLUSION

The signal intensity of bone marrow varies with age and gender in DW images. ADC and the T2 shine-through effect contributed to the bone marrow signal intensity in DW images, and the latter effect may predominate.
