RESUMO
Background: Sexual dysfunction is a common disorder among women, especially during menopause. Metabolic syndrome is a multifactorial disease that, according to previous studies, there is a relationship between the metabolic syndrome and sexual dysfunction among women. The aim of this systematic review and meta-analysis is to obtain the prevalence of Female Sexual Dysfunction (FSD) among women with metabolic syndrome, and to analyze available related evidence. Methods: In this systematic review and meta-analysis, the keywords of MeSH, female sexual dysfunction, FSD, metabolic syndrome were searched in PubMed, Web of Science, Scopus, Science Direct and Google Scholar. The searches were conducted without a lower time limit and until May 2022. Results: The prevalence of FSD among women with metabolic syndrome was found to be 39.3% (95% CI: 28.3-51.5). In the subgroup analysis and in the review of 4 studies, the prevalence of sexual dysfunction in postmenopausal women with metabolic syndrome was 49.8% (95% CI: 26.1-73.6). Analyzing the results of the meta-regression test in examining the effect of the three factors of sample size, year of the study, age, and BMI of the patients on the heterogeneity of the meta-analysis, showed that with the increase of the sample size, the prevalence of sexual dysfunction among women with metabolic syndrome decreases (p < 0.05). Moreover, the prevalence of sexual dysfunction among women with metabolic syndrome increases (p < 0.05) with the increase in the years of conducting studies and the mean of age of women with metabolic syndrome. Also, with increasing mean of BMI of female patients with metabolic syndrome, the prevalence of sexual dysfunction in these women also increases (p < 0.05). Conclusion: Female sexual dysfunction is a global health problem that can affect women's life to a great extent. Metabolic syndrome, which is a set of factors such as obesity, high blood pressure, and diabetes, affects sexual dysfunction in women. From this study, it can be concluded that there is a close relationship between metabolic syndrome and female sexual dysfunction.
RESUMO
BACKGROUND: Chronic fatigue syndrome is a persistent and debilitating disorder. According to several studies, chronic fatigue syndrome has been identified among recovered COVID-19 patients as the most common symptom of long COVID. The aim of this systematic review and meta-analysis study was to obtain the prevalence of chronic fatigue syndrome in long COVID cases. METHODS: In this systematic review and meta-analysis, we analysed reported results of studies that assessed the occurrence of chronic fatigue syndrome among COVID-19 patients four weeks after the onset of symptoms. The study selection was commenced by searching PubMed, Web of Science, Science Direct, Scopus, Embase, and Google scholar using the keywords of Chronic fatigue syndrome, COVID-19, and post-COVID-19 syndrome. The searches were without a lower time limit and until April 2022. Heterogeneity of studies was assessed using the I2 index, and a random effects model was used for analysis. Data analysis was performed within the Comprehensive Meta-Analysis software (version 2). RESULTS: The pooled prevalence of chronic fatigue syndrome four weeks after the onset of COVID-19 symptoms, in 52 studies with a sample size of 127,117, was 45.2% (95% CI: 34.1-56.9%). Meta-regression analysis in examining the effects of the two factors of sample size, and year of study on the changes in the overall prevalence, showed that with increasing sample size, and year of study, the prevalence of chronic fatigue syndrome among long COVID patients (p < 0.05). CONCLUSION: Our results show that the overall prevalence of chronic fatigue syndrome as a long COVID symptom is 45.2%. Chronic fatigue after infection with COVID-19 can negatively affect personal and social lives. Given such significant negative consequences caused by the syndrome, it is recommended that health policymakers allocate funds to reduce the adverse effects of this syndrome, by creating programs to support long COVID patients.
