Oral contraceptives in adolescents: a retrospective population-based study on blood pressure and metabolic dysregulation.

PURPOSE: This study aimed to explore the relationship between oral contraceptive use and blood pressure values and in a national cohort of women adolescents and to investigate the level of coexistence of the high blood pressure levels, dyslipidemia or insulin resistance. METHODS: This is a retrospective cohort study that evaluated data form 14,299 adolescents aged 14 to 17 years. Crude and race-and age-adjusted analyses were performed using Poisson regression to estimate the prevalence ratios. Data clustering analysis was performed using machine learning approaches supported by an unsupervised neural network of self-organizing maps. RESULTS: We found that 14.5% (n = 2076) of the women adolescents use oral contraceptives. Moreover, an increased prevalence of high blood pressure, dyslipidemia, and insulin resistance (all P < 0.001) was observed among adolescents who use oral contraceptives as compared to those who do not. Our analysis also showed that 2.3% of adolescents using oral contraceptives had both high blood pressure levels and dyslipidemia, whereas 3.2% had high blood pressure levels combined with insulin resistance (all P < 0.001). The algorithmic investigative approach demonstrated that total cholesterol, LDLc, HDLc, insulin, and HOMA-IR were the most predicted variables to assist classificatory association in the context of oral contraceptive use among women adolescents with high blood pressure. CONCLUSIONS: These findings suggest that oral contraceptives were associated with an increased prevalence of high blood pressure, dyslipidemia, and insulin resistance among women adolescents. Although the indication of this therapy is adequate to avoid unintended pregnancies, their use must be based on rigorous individual evaluation and under constant control of the cardiometabolic risk factors.

Unusual Manifestation of Membranous Dysmenorrhea: Case Report.

BACKGROUND In the 18th century, Morgagni described membranous dysmenorrhea as the sudden and complete detachment of the decidua during menstruation. This causes intense and painful contractions of the myometrium, aggravated by the expulsion of tissues produced by the decidualization of the endometrium. It is a rare pathology associated with oral contraceptives, ectopic pregnancies, abortions, and natural cycles, with consequent thickening and endometrial decidualization with molding of the tissue of the uterine cavity of membranous appearance. The definitive diagnosis is made by histopathological examination. CASE REPORT A 43-year-old female patient came for urgent consultation for an acute picture of severe pain in the lower abdomen, radiating to the genital area with transvaginal bleeding of 2 h of evolution. She had no significant past medical history. A transvaginal ultrasound was performed and showed an unchanged endometrial cavity. A vaginal examination revealed a foreign body of soft consistency; therefore, a speculum examination was performed, which showed tissue of endometrial origin located in the cervical canal of a reddish spongy texture. The tissue was removed, thus improving the symptomatology, and was sent to the pathological anatomy service for histopathologic diagnosis. CONCLUSIONS Membranous dysmenorrhea is a rare gynecologic disorder with only a few documented cases. According to other case reports, our patient's case, at age 43 years, was an atypical presentation. The clinical features and association with this pathology allowed the diagnosis and its confirmation by histopathological examination.

Trunk variability and local dynamic stability during gait after generalized fatigue induced by incremental exercise test in young women in different phases of the menstrual cycle.

Purpose: The purpose of this study was to identify how generalized fatigue along with hormonal changes throughout the menstrual cycle affects trunk variability and local dynamic stability during gait. Methods: General fatigue was induced by an incremental test on a treadmill, and the menstrual cycle was divided into three phases: follicular, ovulatory, and luteal. Twenty-six healthy, young volunteers (aged 18 to 28 years) who did not use oral contraceptives or other hormonal drugs with a regular menstrual cycle participated in the study. They walked on the treadmill for 4 min at the preferred speed, before the incremental test, followed by four sets of 4 min alternating between walking, also at preferred speed, and resting. From trunk kinematic data, the following were extracted: the mean of the standard deviation along strides, as a measure of variability, and the maximum Lyapunov exponent, as a measure of local dynamic stability (LDS). Results: After the incremental test, variability increased, and LDS decreased. However, they showed a tendency to return to the initial value faster in women compared to previous results for men. In the follicular phase, which has less hormonal release, the volunteers had an almost complete recovery in LDS soon after the first rest interval, suggesting that female hormones can interfere with fatigue recovery. Nevertheless, concerning the LDS, it was significantly lower in the luteal phase than in the follicular phase. Conclusion: Women that are not taking oral contraceptives should be aware that they are susceptible to increased gait instabilities in the pre-menstrual phase after strenuous activities.

Does the use of oral contraceptives or hormone replacement therapy offer protection against the formation or rupture of intracranial aneurysms in women?: a systematic review and meta-analysis.

OBJECTIVE: The aim of this study was to carry out a systematic review of the literature with meta-analysis to evaluate the effect of using oral contraceptive and hormone replacement therapy as a protective factor in the formation of intracranial aneurysms and subarachnoid hemorrhage. METHODS: This is a systematic review of the literature with meta-analysis, using PubMed and Embase as databases and the PRISMA method. Case-control and cohort studies published until December 2022 were included in this review. RESULTS: Four studies were included in this review; three of which were eligible for meta-analysis. Regarding the use of oral contraceptive and the development of subarachnoid hemorrhage, there was a lower risk of aneurysm rupture with an odds ratio 0.65 (confidence interval 0.5-0.85). In the analysis of patients using hormone replacement therapy and developing subarachnoid hemorrhage, there was also a lower risk of aneurysm rupture with an OR 0.54 (CI 0.39-0.74). Only one article analyzed the formation of intracranial aneurysm and the use of hormone replacement therapy and oral contraceptive, and there was a protective effect with the use of these medications. oral contraceptive: OR 2.1 (CI 1.2-3.8) and hormone replacement therapy: OR 3.1 (CI 1.5-6.2). CONCLUSION: The use of hormone replacement therapy and oral contraceptive has a protective effect in intracranial aneurysm rupture and formation.

The use of contraceptives and their nutritional impact on medical students.

OBJECTIVE: This study aimed to analyze the impact of contraceptives on medical students at the Federal University of Paraná and verify adherence, consequences, and lifestyle effects of the contraceptive method used. METHODS: This is an observational, cross-sectional study in which 214 participants answered an online questionnaire composed of 30 questions. For statistical analysis, the Stata® 16.0 software was used, and the mean and standard deviation were estimated to characterize continuous variables with a normal distribution and percentages for categorical variables. For group-to-group comparisons, a one-way ANOVA was used for normal continuous variables and Fisher's exact test for categorical variables. RESULTS: Almost 10% (9.3%) of women used condoms only, and double protection (condom+oral contraceptives) corresponds to 23.4%. Of the 214 participants, 38 reported making exclusive use of long-acting reversible contraception, and 13.6% of the interviewees used oral contraceptives exclusively. More than 88% of the interviewees believe that the medical course provided adequate education on contraception. Regarding lifestyle habits, 71.5% of the students reported alcohol intake, tobacco use, and/or other drug use. CONCLUSION: There was a great diversity of combinations between contraceptive methods used by the medical student at Federal University of Paraná, the most prevalent being the oral contraceptive associated with male condoms. There was a greater association in the use of long-acting reversible contraception in married students. Although 88.3% of the participants believed that they had a good education about contraception at university, only half of them use condoms in sexual relationships. The rate of adherence to alcohol and tobacco among students is considerable, and such practices can negatively affect a nutritional profile, a healthy lifestyle, and safe sexual practices. Brazilian medical schools are fundamental for the advancement of medical education in contraception and for the creation of public policies on family planning.

O impacto do uso de métodos contraceptivos orais na função sexual de mulheres em idade reprodutiva / The impact of the use of oral contraceptive methods on the sexual function of women of reproductive age

Objetivo: Investigar o impacto dos contraceptivos orais hormonais na função sexual de mulheres. Métodos: Estudo transversal realizado por meio do questionário traduzido e validado "Índice da Função Sexual Feminina", capaz de estimar o risco de disfunção sexual feminina. Dados sociodemográficos, ginecológicos, medicamentosos e outros foram avaliados e correlacionados estatisticamente a esse escore, estimando possíveis causas da disfunção sexual, com destaque para o uso de anticoncepcional oral. O estudo foi baseado em uma amostragem por conveniência, incluindo mulheres > 18 anos em idade reprodutiva, de 04/01/2021 a 04/01/2022, obedecendo aos critérios de inclusão e exclusão. Resultados: Participaram deste estudo 105 mulheres com média e desvio-padrão de idade de 23,4 ± 3,8 anos, predominantemente heterossexuais (84,0%) e bissexuais (13,2%). A maioria delas (93,4%) utiliza métodos contraceptivos, sendo esses anticoncepcional oral (45,3%), DIU hormonal (19,8%) e camisinha (17,0%). A composição hormonal mais utilizada foi levonorgestrel (26,4%) e etinilestradiol (25,5%). Oitenta por cento das mulheres são sexualmente ativas, 69,3% delas têm parceria fixa, 42,5% tinham relações quase sempre e 33,0% referiam que as relações sexuais eram sempre satisfatórias. Houve boa adequação da amostra (0,865) e significância estatística (p < 0,0001). Utilizar ou não método contraceptivo apresentou diferença nos domínios desejo, satisfação e dor. Contudo, as questões do histórico sexual foram as que mais apresentaram relevância estatística em relação aos domínios. Conclusão: Apesar de outros estudos serem necessários para provar a hipótese de que os contraceptivos orais têm impacto negativo na função sexual feminina, é clara a importância de os profissionais de saúde já estarem cientes dessa possibilidade e saberem como abordá-la.

Objective: To investigate the impact of hormonal oral contraceptives on women's sexual function. Methods: Cross-sectional study carried out using the translated and validated questionnaire "Index of Female Sexual Function", capable of estimating the risk of female sexual dysfunction. Sociodemographic, gynecological, medication and other data were evaluated and statistically correlated to this score, estimating possible causes of sexual dysfunction, with emphasis on the use of oral contraceptives. The study was based on a convenience sample, including women > 18 years of reproductive age, from 01/04/2021 to 01/04/2022, following inclusion and exclusion criteria. Results: The study included 105 women with a mean and standard deviation of (23.4 ± 3.8) years old, predominantly heterosexual (84.0%) and bisexual (13.2%). Most of them (93.4%) use contraceptive methods, these being (45.3%) oral contraceptives, (19.8%) hormonal IUDs and (17.0%) condoms. The most used hormonal composition was levonorgestrel (26.4%) and ethinylestradiol (25.5%). Eighty percent of the women are sexually active, 69.3% of them have a steady partner, 42.5% almost always had sex and 33.0% said that sex was always satisfactory. There was good sample adequacy (0.865) and statistical significance (p < 0.0001). Using or not using a contraceptive method showed a difference in the desire, satisfaction and pain domains. However, sexual history questions were the ones that showed the most statistical relevance in relation to the domains. Conclusion: Although further studies are needed to prove the hypothesis that oral contraceptives have a negative impact on female sexual function, it is clear that health professionals are already aware of this possibility and know how to approach it.

Anticoncepção oral e hipotrofia muscular: existe correlação? / Oral contraception and muscle atrophy: is there a correlation?

As pílulas anticoncepcionais consistem na formulação combinada de um estrogênio e um progestagênio ou em apresentações simples de progestagênio isolado com a finalidade de bloquear a ovulação e alterar as condições do útero e das tubas uterinas, bloqueando parcialmente a foliculogênese e a inibição do pico de gonadotrofinas. Desse modo, no que concerne à temática, diversas publicações na mídia de ampla divulgação afirmam que os anticoncepcionais orais têm papel importante na sarcopenia e na hipotrofia, incluindo perda de força muscular e redução do desempenho físico. Assim, o presente trabalho tem por objetivo avaliar, por meio de pesquisas de artigos, a correlação entre anticoncepcionais hormonais orais e hipotrofia muscular. Foi concluído que os artigos científicos especializados no tema são ainda bastante inconclusivos, sugerindo que há indicações de que usuárias de anticoncepcional oral sejam mais suscetíveis ao dano muscular induzido por exercícios, contudo ainda não há consenso.

Anticonception pills consist of a combined formulation of an estrogen and a progestogen or simple presentations of progestogen alone with the purpose of blocking ovulation and altering the conditions of the uterus and uterine tubes, partially blocking folliculogenesis and inhibiting the gonadotropin peak. Thus, with regard to the subject, several widely publicized media publications claim that oral contraceptives play an important role in sarcopenia and hypotrophy, including loss of muscle strength and reduced physical performance. So, the present work aims to evaluate through article searches the correlation between oral hormonal contraceptives and muscle hypotrophy. It was concluded that scientific articles specialized on the subject are still quite inconclusive, suggesting that there are indications that oral contraceptive users are more susceptible to exercise-induced muscle damage, however there is still no consensus.

Oral combined hormonal contraceptive associated with protection against allodynia in migraine in a cross-sectional study.

INTRODUCTION: For the most part, migraine afflicts young women who often need to use the hormonal contraceptive method. OBJECTIVE: To evaluate the effects of using exogenous estrogen, present in combined hormonal contraceptives (CHC) and progestin-only methods on the prevalence of allodynia in women with migraine. METHODS: Study comprising women diagnosed with migraine, with or without aura, who were not pregnant, breastfeeding, or menopausal. The study was conducted via the digital platform. Data were collected relating to demographics, contraceptive method, anthropometric information, smoking habits, and migraine-related symptoms. The participants then answered the following validated, self-administered questionnaires: Migraine Disability Assessment (MIDAS), Allodynia Symptom Checklist, Generalized Anxiety Disorder (GAD-7), and Beck's Depression Inventory (BDI). In order to determine the variables associated with allodynia, two binary logistic regression models were used. RESULTS: Four hundred eighty-six women took part in the study. Of these, 205 used CHC, 89 used a progestin-only method, and 192 participants did not use any form of hormonal contraception. Allodynia was identified in 411 (84.6%) participants. Allodynia was linked to the presence of aura (OR = 2.76; CI 95% 1.55-4.91; p = 0.001), menstrually related migraine (OR = 2.14; CI 95% 1.28-3.57; p = 0.004), greater disability (MIDAS score 23 vs. 8; p < 0.001), depression (BDI score 14 vs. 10; p < 0.001), and anxiety (GAD-7 score 11 vs. 8; p < 0.001). In adjusted analysis, CHC was associated to protection against allodynia when jointly evaluated all CHC regimens (OR = 0.49 CI 95% 0.26-0.92; p = 0.028), as well as oral CHC individually (OR = 0.48 CI 95% 0.25-0.92; p = 0.027). CONCLUSION: CHC reduced the chances of women with migraine getting allodynia.

Associations between contraceptive availability and rate of subsequent legal abortions in Colombia: A historical cohort analysis.

OBJECTIVE: To describe factors associated with subsequent abortions in Colombia and evaluate whether high-efficacy contraceptive availability (IUD) post-index abortion was associated with higher efficacy contraceptive initiation and fewer subsequent abortions within 2 years. METHODS: The study population comprised patients aged 15-44 years who underwent index abortion in 2017 at four clinics in Bogotá, Colombia. Using charts, we conducted a retrospective cohort study with 2-year follow-up (2017-2019) after the index abortion for outcomes of contraceptive initiation and subsequent abortion. We evaluated associations between demographic or clinical characteristics and outcomes using Pearson chi-square and multivariate logistic regression. RESULTS: Of 9175 patients with index abortion, 3409 (37.2%) initiated an intrauterine device (IUD) and 467 (5.1%) had a subsequent abortion within the study period (2017-2019). IUD availability (adjusted odds ratio [aOR], 1.64; 95% confidence interval [CI], 1.39-1.93) and insurance use (aOR, 5.03; 95% CI, 4.37-5.78) were associated with high-efficacy contraceptive initiation; medication abortion was inversely associated (aOR, 0.24; 95% CI, 0.22-0.27). Initiation of no (aOR, 4.94; 95% CI, 3.59-6.80) or moderate-efficacy (injection: aOR, 4.21 [95% CI, 3.14-5.62]; oral contraceptive pill: aOR, 4.60 [95% CI, 3.21-6.59]) methods were associated with subsequent abortion. CONCLUSION: Subsequent abortion is inversely associated with initiated postabortion contraceptive efficacy, which is modifiable on a systems level by improving access to effective postabortion contraception.

Bone Density and Bone Geometry in University Athletes From Sports With Different Levels of Impact: Simultaneous Association With Multiple Factors.

ABSTRACT: Moraes, MS, Fernandes, RA, Moreno, YMF, Pelegrini, A, and Silva, DAS. Bone density and bone geometry in university athletes from sports with different levels of impact: simultaneous association with multiple factors. J Strength Cond Res 36(11): 3113-3121, 2022-The aim of this study was to use the bone loading unit (BLU) classification to compare bone density and bone geometry of sports with different levels of impact, simultaneously controlling the multiple factors that interfere with bone metabolism in athletes. Overall, 167 university athletes (92 men) participated in the study. Bone mineral density (BMD), strength index, cross-sectional area (CSA) at the moment of inertia, section modulus (Z), CSA, neck-shaft angle (NSA), and hip axis length (HAL) were measured. Sports were categorized by level of impact, high BLU (higher impact) and moderate/low BLU (lower impact). Covariates were fat mass, lean tissue mass, training volume, time of practice, dietary supplementation, use of oral contraceptives and menstrual status. Multiple linear regression with 5% significance level ( p < 0.05) was used. In men, HAL was higher in sports with high BLU compared with those with moderate/low BLU (ß: -0.21; R2 : 0.30; p = 0.03). In women, NSA was higher in sports with moderate/low BLU compared with those with high BLU (ß: 0.31; R2 : 0.11; p = 0.02). There was no difference between BLU groups for BMD. These results persisted when the simultaneous interference of covariates was controlled. Thus, this study recommends BLU to classify sports and reinforces the importance of monitoring HAL and NSA in athletes in addition to the control of multiple factors that interfere with bone metabolism, because they influence physical performance and bone health during and after athletic life.

High prevalence of sexual infection by human papillomavirus and Chlamydia trachomatis in sexually-active women from a large city in the Amazon region of Brazil.

BACKGROUND: The Human Papillomavirus (HPV) and Chlamydia trachomatis are the most prevalent Sexually Transmitted Infections (STIs) worldwide, and are associated cervical cancer and pelvic inflammatory disease, respectively. However, 80% of women testing positive are asymptomatic. In the Amazon region, young women, in particular, are widely exposed to the infections and their consequences. OBJECTIVES: Determine the prevalence of sexual infection by HPV and C. trachomatis in young, sexually-active women treated at a university health program in a large city of the Brazilian Amazon region. METHODS: We amplified the L1 gene of HPV. We amplified ompA gene of C. trachomatis by nested PCR, and the study participants filled in a questionnaire on their social, epidemiological, and reproductive health characteristics. The data were analyzed using the Odds Ratio, to evaluate the degree of association of these variables with the observed infections. RESULTS: The prevalence of infection by HPV was 15.5% (47/303). This infection was recorded in 32.2% of the women of less than 25 years of age (OR:3.02 [CI95%] = 1.32-6.92; p = 0.014), 17.9% of the single women (OR: 2.41 [CI95%] = 1.22-4.75; p = 0.014), 23.8% of the women that reported having first sexual intercourse at less than 15 years of age (OR: 2.22 [CI95%] = 1.16-4.23; p = 0.021), 20% of those that reported having had more than one sexual partner during their lifetime (OR: 3.83 [CI95%] = 1.56-9.37; p = 0.003), and in 28.3% that use oral contraceptives (CI95% = 1.33-5.43; p = 0.008). The prevalence of sexual infection by C. trachomatis was 4.6% (14/303), and this bacterium was present in 16.1% of the young women of less than 25 years of age (OR: 2.86 [CI95%] = 1.33-5.43; p = 0.008). CONCLUSIONS: We found a high prevalence of HPV in young, unmarried women who started their sex lives early, who had several sexual partners in their lives and who used oral contraceptives. The prevalence of C. trachomatis was high only in young women. Our data are in accordance with other studies in Brazil and in the world and may serve to base the formulation of diagnostic and screening measures for these infections in women in the Amazon.

Opciones e indicaciones en el manejo del istmocele / Options and indications in the management of isthmocele

INTRODUCCIÓN: El istmocele es un defecto en la cicatrización del sitio de una histerotomía, que puede cursar con sangrado posmenstrual, dolor pélvico, dismenorrea, dispareunia e infertilidad secundaria. Esta patología ha ido incrementando su prevalencia dado el aumento de la tasa de cesáreas en todo el mundo. OBJETIVO: Se realizó una revisión sobre el istmocele y su manejo, presentando sus indicaciones específicas y las complicaciones asociadas a esta patología. MÉTODO: Se llevó a cabo una búsqueda en PubMed, Embase, Scopus y Google Scholar, en la que se encontraron 868 artículos, de los cuales se revisaron 30 al aplicar los criterios de inclusión y exclusión. DISCUSIÓN: El istmocele es cada vez más frecuente. Tiene una prevalencia cercana al 60% posterior a la realización de una cesárea y aumenta hasta valores del 100% con tres de ellas. Los métodos diagnósticos más utilizados son la ecografía transvaginal y la histerosonografía. Su abordaje es habitualmente quirúrgico, aunque existe la posibilidad de intentar tratamiento médico en algunos casos. CONCLUSIONES: Es necesario determinar el grosor miometrial para poder establecer un plan de manejo adecuado. Además, se ameritan estudios que realicen un seguimiento a largo plazo y que aporten mayor evidencia para la realización de cada procedimiento. Después de clasificar el tipo de defecto, el tratamiento quirúrgico del istmocele se debe ofrecer a pacientes sintomáticas y a aquellas con defectos grandes y que desean mantener la fertilidad.

INTRODUCTION: The isthmocele is a defect in the healing of the site of a hysterotomy, which can present with post-menstrual bleeding, pelvic pain, dysmenorrhea, dyspareunia and secondary infertility. This pathology has been increasing its prevalence given the increase in the rate of cesarean sections worldwide. OBJECTIVE: A review will be carried out of the isthmocele and its management, presenting its specific indications and the complications associated with this pathology. METHOD: A search was carried out in databases such as PubMed, Embase, Scopus and Google Scholar, finding a total of 868 articles, of which 30 of them were reviewed when applying the inclusion and exclusion criteria. DISCUSSION: Isthmocele is an increasingly frequent pathology, having a prevalence of 60% after performing a cesarean section and increasing to 100% with 3 of them. There are multiple diagnostic methods, mainly transvaginal ultrasound and sono-hysterosonography. The approach to this pathology is usually surgical, although there is the possibility of trying medical treatment in some cases. CONCLUSIONS: It is necessary to determine the myometrial thickness in order to establish an adequate management plan. Additionally, long-term follow-up studies are warranted and provide more evidence for the performance of each procedure. After classifying the type of defect, surgical treatment of the isthmocele should be offered to symptomatic patients or those with large defects and who desire future fertility.

Folate and vitamin B12 status: temporal evaluation after mandatory fortification in Brazil.

OBJECTIVES: To perform temporal evaluation of folate and vitamin B12 status and their associated factors in a Brazilian population exposed to mandatory fortification. METHODS: Data from the cross-sectional population-based studies 2008 and 2015 Health Surveys of São Paulo, including individuals ≥ 20 years, both sexes, N = 549 in 2008 and N = 610 in 2015. Folate and vitamin B12 biomarkers status, B-complex supplements and medications use, and dietary intake were assessed. RESULTS: Serum folate concentrations increased in the entire population, adults and older adults in 2015 compared to 2008, while serum vitamin B12 concentration increased only in older adults. B-complex supplement use raised in 2015, reflecting in serum vitamins status. Overall serum vitamin B12 deficiencies (<200 pg/mL) were 23.2% and 21.2%, while serum folate deficiencies (<4 ng/mL) were 4.1% and 1.5% in 2008 and 2015, respectively. The lowest quintile of serum folate (≤8.7 ng/mL) was positively associated with smoking and oral contraceptive use, while the highest quintile (≥17.8 ng/mL) was inversely associated with smoking and positively with B-complex supplement use. The odds of having vitamin B12 deficiency was inversely associated with B-complex supplement use, higher serum folate median, higher dietary vitamin B12 intake and positively associated with using oral contraceptive. CONCLUSION: Overall deficiency of folate has decreased in 2015, being almost non-existent. Low vitamin B12 status presented similar proportions in the overall population comparing both periods, except for older adults. Different predictive variables were identified to better understand vitamins status outcomes in the most recent period of the study.

ERICA: cardiovascular risks associated with oral contraceptive use among Brazilian adolescents

Abstract Objective: To investigate the association between oral contraceptive use and cardiovascular risks, including metabolic syndrome and their components in Brazilian adolescents. Method: This study used data from the Study of Cardiovascular Risks in Adolescents (Estudo de Riscos Cardiovasculares em Adolescentes - ERICA), a nationwide, cross-sectional, school-based study with individuals aged 12-17 years. Sociodemographic variables and OC use were assessed by a self-administered questionnaire. International Diabetes Federation criteria were used to define metabolic syndrome. Descriptive statistics were reported as prevalence and their respective confidence interval of 95% of oral contraceptives according to variables. Logistic regression was performed. Crude and adjusted odds ratios were calculated. Results: This subsample was composed of 22,682 female adolescents, of which 12.65% reported using oral contraceptives and their use was associated with hypertension and hypertriglyceridemia. These associations remained statistically significant after adjusting for age, school region, race, and tobacco use with an increase of 2.68 (1.66 - 4.32) and 3.45 (2.56 - 4.65) times, respectively. Conclusion: The present study was the first to examine the association between the use of oral contraceptives and cardiovascular risk factors among the largest number of female Brazilian adolescents. This method was significantly associated with hypertension, hypertriglyceridemia. Teenagers using oral contraceptives should be monitored for side effects, including blood pressure measurements and advised to avoid smoking.

These associations remained statistically significant after adjusting for age, school region, race, and tobacco use with an increase of 2.68 (1.66 - 4.32) and 3.45 (2.56 - 4.65) times, respectively. CONCLUSION: The present study was the first to examine the association between the use of oral contraceptives and cardiovascular risk factors among the largest number of female Brazilian adolescents. This method was significantly associated with hypertension, hypertriglyceridemia. Teenagers using oral contraceptives should be monitored for side effects, including blood pressure measurements and advised to avoid smoking.
