Risk factors related to the SARS-CoV-2 vaccine additional doses hesitancy among pregnant and non-pregnant people of reproductive age and partners: A Brazilian cross-sectional study.

OBJECTIVE: The aim of this study was to assess the predictors of acceptance and hesitancy of additional doses of any SARS-CoV-2 (COVID-19) vaccine among pregnant or recently pregnant and non-pregnant people of reproductive age and partners in Brazil. METHODS: We conducted an online cross-sectional study from June 2022 to April 2023 and invited women and partners between 18 and 49 years old to participate. We employed a snowball strategy to reach all potential eligible participants. Our primary outcome was the acceptance rate of the COVID-19 booster vaccine. We estimated the frequency and percentage for the three groups and compared categorical variables using the Chi-square test. Moreover, bivariate, backward stepwise regression, and subgroup analyses were performed to evaluate risk factors and predictors of COVID-19 vaccine booster hesitancy. We reported the effect size as OR with a 95% CI. RESULTS: We included 1487 participants, and among them, 334 (22.5%) were pregnant or recently pregnant people, 905 (60.8%) were non-pregnant people, and 247 (16.6%) were male partners. Pregnant and recently pregnant people showed greater hesitancy for the COVID-19 vaccine booster than non-pregnant people (28% vs 15%, P < 0.001) and male partners (28% vs 16%, P < 0.001). Non-pregnant women accepted the COVID-19 vaccine more often than pregnant or recently pregnant people (OR 1.75; 95% CI: 1.13-2.70). The associated factors to the reduced COVID-19 vaccine booster acceptance were family income between US$ 566-945.00 (54%), evangelic religion (65%), concern about vaccine safety (80%) and perceived common vaccine importance (93%). CONCLUSION: Pregnant people were more hesitant than non-pregnant people to accept the COVID-19 booster vaccine. Family income, religious beliefs, vaccine safety concerns, and perceived common vaccine importance were significant barriers to accepting COVID-19 booster vaccines. The impact of these factors was more evident among pregnant or recently pregnant people, emphasizing the harmful effect of misinformation among this vulnerable population.

Opinion and experience of Brazilian women regarding menstrual bleeding and use of combined oral contraceptives.

OBJECTIVE: To describe the opinion and experience of Brazilian women regarding menstruation and the use of combined oral contraceptives (COCs) to control monthly bleeding and induce amenorrhea. METHODS: Women attending regional public healthcare clinics for non-gynecologic conditions, and female members of staff from university schools unrelated to the field of medicine completed a questionnaire. RESULTS: Of the 1111 women interviewed, 64.3% reported disliking menstruation. The desired frequency of bleeding was never (65.3%), less than monthly (18.2%), and every month or more often (16.5%). More than 60% of the women reported that they would use COCs to control menstrual bleeding, 82.0% would use COCs to reduce the amount of bleeding experienced, and 86.1% would use COCs to induce amenorrhea. When compared with women who disliked menstruation, those who reported that they liked to experience monthly bleeding had fewer years of schooling (OR1.98; 95% CI, 1.30-2.97), low socioeconomic status (OR 1.66; 95% CI, 1.12-2.46), fewer days of menstruation each month (OR 1.62; 95% CI, 1.11-2.36), and 1 or more child (OR 1.13; 95% CI, 1.01-1.26). CONCLUSION: Many of the women surveyed disliked monthly menstruation and were interested in the use of COCs to control menstrual bleeding and induce amenorrhea.

Premenstrual syndrome as reported by Brazilian women.

OBJECTIVE: To describe the perspectives and attitudes of Brazilian women toward premenstrual syndrome (PMS). METHODS: An exploratory study was conducted in 6 major cities: 1 in each geographic region of Brazil and 1 in the Federal District. Participants were women aged 18-40years who consulted at public healthcare services or who were members of staff/faculty at university. RESULTS: Of 1053 women, 96.1% had heard of PMS; 65.4% considered that all or almost all women experienced the condition; 87.5% stated that symptoms occurred prior to menstruation; and 60.3% thought that they had PMS at the time of the interview. The emotional and physical symptoms most frequently mentioned were nervousness/anxiety (76.4%); mood swings/crying (55.7%); pain, swelling, and tenderness of the breasts (37.3%); and cramps (45.4%). CONCLUSION: Premenstrual syndrome was reported by a large number of Brazilian women; actions need to be taken to provide more effectively the specific information required by both lay people and healthcare professionals.

Women's preferences for vaginal antimicrobial contraceptives. V: attitudes of Brazilian women to the insertion of vaginal products.

The rapid spread of HIV/AIDS in the female population increases the urgency of developing new formulations that offer protection from this disease as well as other sexually transmitted infections. In many cultures, women do not readily accept touching their genitals or inserting products into their vaginas. Information on this subject was collected during a study involving 635 women in Brazil to determine the preferred attributes of vaginal products. Seventy-six percent would use an idealized contraceptive method that offered dual protection even though it could only be inserted with a finger and 96% would use this method if it could only be placed with an applicator. Qualitative analyses of responses to open questions suggest that the majority of Brazilian women studied did not like to touch their vagina with their finger or to insert devices. Although the introduction of safe and effective vaginal microbicides into many cultural settings can be successful, it should be accompanied by significant efforts to educate women about their bodies.
