Awareness of Hypertension in Reproductive-Aged Women Living With Chronic Kidney Disease.

Background: Hypertension is the most important modifiable cardiovascular risk factor among women. Chronic kidney disease (CKD), which affects 1 in 10 reproductive-aged women, increases the risk of hypertension; however, awareness of hypertension in this population is unknown. This study aimed to determine hypertension awareness among reproductive-aged women living with chronic kidney disease. Methods: Women aged 18 to 50 years with CKD were recruited from nephrology clinics in Calgary, Alberta, Canada. Participants completed a semistructured interview and focused chart review, serum and urine laboratory assessment, and a physical examination that included anthropomorphic measurements and 2 automated office blood pressure readings. Hypertension was defined according to the use of ≥ 1 antihypertensive medications and/or an automated office blood pressure reading of ≥ 135/85 mm Hg. Data were stratified by hypertension status, as well as by awareness, and descriptively presented as mean ± standard deviation, numerical values, and percentages. Results: Sixty-three participants with CKD were included. Thirty-eight (60%) participants had hypertension according to study definitions. Of those with hypertension, 30 participants (79%) were aware of their hypertension status. Conclusions: Hypertension awareness is relatively high in reproductive-aged women living with CKD. However, hypertension awareness is the critical component for hypertension management, and further work is necessary to optimize reduction of cardiovascular risk in this important population.

Contexte: L'hypertension est le principal facteur de risque cardiovasculaire modifiable chez les femmes. La néphropathie chronique, qui touche une femme en âge de procréer sur 10, augmente le risque d'hypertension, mais le niveau de sensibilisation de cette population à ce sujet est inconnu. La présente étude visait à déterminer le niveau de sensibilisation à l'hypertension chez les femmes en âge de procréer atteintes de néphropathie chronique. Méthodologie: Des femmes âgées de 18 à 50 ans atteintes de néphropathie chronique ont été recrutées dans les cliniques de néphrologie de Calgary, en Alberta (Canada). Les participantes ont été soumises à des entrevues semi-structurées, un examen ciblé du dossier médical, des analyses de laboratoire du sérum et de l'urine et un examen physique incluant des mesures anthropométriques et deux lectures automatisées de la pression artérielle réalisées en cabinet. L'hypertension a été définie de la façon suivante : (1) l'utilisation de ≥ 1 agent antihypertenseur, et/ou (2) une lecture automatisée de la pression artérielle en cabinet ≥ 135/85 mmHg. Les données ont été stratifiées selon le statut d'hypertension et le niveau de sensibilisation, et elles sont présentées de façon descriptive par la moyenne ± l'écart-type, les valeurs numériques et les pourcentages. Résultats: Soixante-trois participantes atteintes de néphropathie chronique ont été incluses dans l'étude. Trente-huit (60 %) participantes étaient atteintes d'hypertension selon la définition utilisée dans l'étude. Parmi les participantes hypertendues, 30 (79 %) étaient conscientes de leur statut d'hypertension. Conclusions: Le niveau de sensibilisation à l'hypertension est relativement élevé parmi les femmes en âge de procréer atteintes de néphropathie chronique. Toutefois, la sensibilisation à l'hypertension est un élément clé pour sa prise en charge, et d'autres travaux sont nécessaires pour optimiser la réduction du risque cardiovasculaire dans cette population importante.

Female Reproductive Health and Contraception Use in CKD: An International Mixed-Methods Study.

Rationale & Objective: Female reproductive health is recognized as a predictor of morbidity, mortality, and quality of life, although data in the setting of chronic kidney disease (CKD) are limited. Study Design: A mixed-methods study was employed. Phase 1 was an anonymous, internet-based survey. Phase 2 was semistructured interviews offered to all respondents upon survey completion. Setting & Participants: The survey was disseminated internationally from October 4, 2021, to January 7, 2022, to individuals aged 18-50 years with both a uterus and CKD diagnosis. Outcomes: Menstrual health and contraceptive use by CKD stage (dialysis, nondialysis CKD, and transplant). Analytical Approach: Survey data were analyzed using descriptive statistics. Interview data were analyzed using the framework method of analysis. Results: Of 152 respondents, 98 (mean age 33 ± 0.7 years; n = 20 dialysis, n = 59 nondialysis CKD, n = 19 transplant) satisfied the inclusion criteria, representing 3 continents. The most common causes of CKD among survey respondents were hereditary causes in dialysis (n = 6, 30%) and glomerulonephritis in nondialysis CKD (n = 22, 37%) and transplant (n = 6, 32%). The majority reported heavy menstrual bleeding (n = 12, 86% dialysis; n = 46, 94% nondialysis CKD; n = 14, 100% transplant). Less than half of participants were consistently able to afford period products. Condoms were the most common contraceptive reported. Most participants reported no contraceptive use (n = 10, 50% dialysis; n = 37, 63% nondialysis CKD; n = 7, 37% transplant), primarily because of "fear". Interviews (n = 6) revealed a perception of a relationship between kidney function and menstrual health, concerns about contraceptive use, and a desire for greater multidisciplinary care to improve kidney and reproductive health. Limitations: Self-reported outcomes, need for internet access and a device. Conclusions: Abnormal menstruation and period poverty (ie, inability to afford period products and the socioeconomic consequences of menstruation) were common, and contraceptive use was low among female individuals with CKD, highlighting an important gap in the sex-specific care of this population. Plain-Language Summary: Chronic kidney disease (CKD) in female individuals is accompanied by menstrual disorders and low contraceptive use. However, most data are limited to the dialysis and transplant populations. Therefore, this mixed-methods study aimed to describe self-assessed menstruation and contraceptive use across all stages of CKD. People aged 18-50 years with a uterus and CKD diagnosis were invited to participate in an online survey shared internationally as well as an optional telephone interview. Abnormal menstruation and period poverty (ie, inability to afford period products and the socioeconomic consequences of menstruation) were common, and contraceptive use was low among female individuals with CKD, highlighting an important gap in the sex-specific care of this population.

Female sex-specific considerations to improve rigor and reproducibility in cardiovascular research.

Cardiovascular disease is the leading cause of death in women. Despite recognition of sex-specific differences in cardiovascular health, females are underrepresented across all aspects of cardiovascular research, playing a key role in reducing rigor and reproducibility in cardiovascular research and contributing to these poorer health outcomes. Therefore, we propose a framework to capture factors associated with the female sex at the preclinical, recruitment, data collection, and data analysis stages. In preclinical cardiovascular research, female experimental models are commonly excluded despite similar variability in findings compared with males. To reduce this sex bias, the inclusion of female models and the incorporation of sex as a biological variable are critical to improve reproducibility and inform clinical research and care. Although funding agencies have mandated the inclusion of women in clinical trials, greater efforts are needed to achieve optimal participation-to-prevalence ratio to increase the generalizability of results to real-world settings. Female participants face more stringent exclusion criteria in research compared with males owing to sex-specific factors. However, their routine exclusion from cardiovascular research is not only unethical but limits generalizability and applicability to clinical practice. Identifying sex assigned at birth, collecting information on female sex-specific and -predominant factors associated with cardiovascular health and risk, and stratifying data by sex, including adverse events, are essential to ensure reproducibility and relevance of findings to target populations. Increasing female representation and the incorporation of female sex-specific cardiovascular risk factors in cardiovascular research will not only lead to enhanced rigor and reproducibility but improved cardiovascular health for all.

Gender-affirming estrogen therapy route of administration and cardiovascular risk: a systematic review and narrative synthesis.

Transgender women (individuals assigned male sex at birth who identify as women) and nonbinary and gender-diverse individuals receiving gender-affirming estrogen therapy (GAET) are at increased cardiovascular risk. Nonoral (i.e., patch, injectable) compared with oral estrogen exposure in cisgender women (individuals assigned female sex at birth who identify as women) may be associated with lower cardiovascular risk, though whether this applies to transgender women and/or gender-diverse individuals is unknown. We sought to determine the association between the route of estrogen exposure (nonoral compared with oral) and cardiovascular risk in transgender women and gender diverse individuals. Bibliographic databases (MEDLINE, Embase, PsycINFO) and supporting relevant literature were searched from inception to January 2022. Randomized controlled trials and observational studies reporting cardiovascular outcomes, such as all-cause and cardiovascular mortality, adverse cardiovascular events, and cardiovascular risk factors in individuals using nonoral compared with oral gender-affirming estrogen therapy were included. The search strategy identified 3,113 studies, 5 of which met inclusion criteria (3 prospective cohort studies, 1 retrospective cohort study, and 1 cross-sectional study; n = 259 participants, range of duration of exposure of 2 to 60 mo). One out of five studies reported on all-cause and cardiovascular mortality or adverse cardiovascular events. All five studies reported lipid levels [low-density lipoprotein (LDL), high-density lipoprotein (HDL), triglycerides (TG), and total cholesterol (TC)], whereas only two studies reported systolic blood pressure (SBP) and diastolic blood pressure (DBP). Limited studies have examined the effect of the route of GAET on all-cause cardiovascular mortality, morbidity, and risk factors. In addition, there is significant heterogeneity in studies examining the cardiovascular effects of GAET.NEW & NOTEWORTHY This study is the first to summarize the potential effect of nonoral versus oral gender-affirming estrogen therapy use on cardiovascular risk factors in transgender women or nonbinary or gender-diverse individuals. Heterogeneity of studies in reporting gender-affirming estrogen therapy formulation, dose, and duration of exposure limits quantification of the effect of gender-affirming estrogen therapy on all-cause and cardiovascular mortality, adverse cardiovascular events, and cardiovascular risk factors. This systematic review highlights the needs for large prospective cohort studies with appropriate stratification of gender-affirming estrogen therapy by dose, formulation, administration route, and sufficient follow-up and analyses to limit selection bias to optimize the cardiovascular care of transgender, nonbinary, and gender-diverse individuals.

Female Reproductive and Gynecologic Considerations in Chronic Kidney Disease: Adolescence and Young Adulthood.

Chronic kidney disease (CKD) increasingly affects younger people, including adolescents and young adults. CKD among females is accompanied by unique reproductive and gynecologic health concerns; though to date, this area has not been well studied. Hormonal disruptions attributed to CKD may underlie the high prevalence of abnormal uterine bleeding and influence the age of menarche in adolescents. Period poverty as a socioeconomic barrier further exacerbates the female-specific burdens of CKD. Reduced fertility in CKD is likely multifactorial and may be related to a reduction in ovarian reserve, reproductive hormone disturbances, and gonadotoxic medication use in addition to low sexual function and activity. Fertility, sexual function and activity, and risk of sexually transmitted infections increase with transplantation. Pregnancy is possible at any stage of CKD, although often accompanied by high risks of maternal and fetal complications. Contraception is thus an important consideration in CKD, but use is low and the risks and benefits of different forms in the setting of CKD are not well characterized. Though patients with CKD report reproductive health as an important element of care, many nephrologists report lack of confidence and training in this area, highlighting the need for targeted research and education. The unique reproductive health care needs of the growing transgender youth population warrant attention in nephrology training with multidisciplinary input. This review will discuss female reproductive health and gynecologic considerations in adolescents and young adults with CKD while proposing clinical and research strategies to improve this understudied yet important aspect of kidney care.
