Interpersonal Stressors and Resources for Support: Associations with Lower Urinary Tract Symptoms and Impact Among Women

Pathways from Adverse Childhood Family Environment to Lower Urinary Tract Symptoms and Impact Among Women

Background: To advance existing knowledge, this study examined mechanisms that may link retrospectively reported adverse childhood family environment (ACFE) to lower urinary tract symptoms and their impact (LUTS/impact), a composite variable with four levels (bladder health and mild, moderate, or severe LUTS/impact), among women (n = 1,026) in the Coronary Artery Risk Development in Young Adults cohort study. A prior study demonstrated that ACFE was associated with greater LUTS/impact. Materials and Methods: In 2000-01, the frequency of ACFE events was retrospectively assessed. In 2012-13, data on LUTS/impact were collected. Between 1985-86 and 2010-11, data on proposed mediators were collected at varying time points and averaged to form composite variables. A series of proportional odds ordinal logistic regression analyses were conducted. LUTS/impact was regressed on ACFE, adjusting for age, race, education, and parity. A single proposed mediator was added to the model at one time to determine whether the strength of the association between ACFE and LUTS/impact was attenuated. Results: When entered into regression models individually, life stressors, low levels of emotional support, and depressive symptoms each significantly attenuated the association between ACFE and LUTS/impact, with the association becoming nonsignificant when depressive symptoms were entered. Remaining proposed mediators (social network extensiveness, health behaviors, physiological health, cognitive function) did not mediate the association. Conclusions: ACFE may place women at risk for repeated or chronic episodes of experiencing life stressors, low support, and depressive symptoms during early and midlife adulthood, which in turn may place women at risk for more LUTS and impact during midlife adulthood.

The brain, gut, and bladder health nexus: A conceptual model linking stress and mental health disorders to overactive bladder in women

OBJECTIVE

A small, but growing literature links stressors and mental health disorders (MHDs) across the life course to overactive bladder (OAB) and urinary incontinence symptoms. Mechanisms by which stressors and MHDs may impact bladder health are not fully understood, limiting novel prevention and treatment efforts. Moreover, potential biopsychosocial mechanisms involving the brain and gut have not been considered in an integrated, comprehensive fashion.

METHODS

Members of the prevention of lower urinary tract symptoms Research Consortium developed conceptual models to inform research on biopsychosocial mechanisms through which stress and MDHs may impact bladder health among girls and women, focusing on brain and gut physiology.

RESULTS

Two conceptual models were developed-one to explain central (brain-based) and peripheral (gut-based) mechanisms linking stressors and MHDs to OAB and bladder health, and one to highlight bidirectional communication between the brain, gut, and bladder. Traumatic events, chronic stressors, and MHDs may lead to a maladaptive stress response, including dysregulated communication and signaling between the brain, gut, and bladder. Gut bacteria produce molecules and metabolites that alter production of neurotransmitters, amino acids, short-chain fatty acids, and inflammatory immune response molecules that mediate communication between the gut and brain. Microbiota signal neurogenesis, microglia maturation, and synaptic pruning; they also calibrate brain-gut-bladder axis communication through neurotransmission and synaptogenesis, potentially influencing bladder symptom development. Life course trajectories of risk may be prevented or interrupted by central and peripheral resources for neuropsychological resilience.

CONCLUSIONS

Depicted pathways, including brain-gut-bladder communication, have implications for research and development of novel prevention and treatment approaches.

Discrimination and bladder health among women in the CARDIA cohort study: Life course and intersectionality perspectives

OBJECTIVE

This study examines whether discriminatory experiences are associated with lower urinary tract symptoms (LUTS) and their impact among 972 women in the Coronary Artery Risk Development in Young Adults (CARDIA) cohort study, which recruited participants from 4 cities in the United States.

METHOD

Exposure to discrimination was assessed 3 times (1992-93, 2000-01, 2010-11) and averaged across assessments. Participants separately reported whether they experienced discrimination on the basis of their gender, race or color, and socioeconomic position or social class. For each social identity, discrimination was assessed in 6-7 settings (e.g., when getting a job, medical care, or housing). At different time points, women who reported discriminatory experiences for a given social identity were asked how frequently the discrimination occurred and how stressful experience(s) were. Following the 2010-11 assessment, data on LUTS and their impact were collected. Women were classified into bladder health versus mild, moderate, or severe symptoms/impact clusters.

RESULTS

More Black than White women reported discriminatory experiences across all social identities and most settings. Perceived stress of discriminatory experiences did not differ between Black and White women. In analyses stratified by race and social identity, White women reported LUTS/impact with discriminatory experiences in more settings, more frequent discriminatory experiences across settings, and each additional social identity for which discrimination was experienced. Black women reported LUTS/impact with more frequent discriminatory experiences across settings. For Black women, greater perceived stress of both gender and race discrimination were associated with LUTS/impact. For White women, only greater perceived stress of race discrimination was associated with LUTS/impact.

CONCLUSIONS

This is one of the first studies to examine discrimination in relation to LUTS/impact. Additional research is needed to better understand differences in how discriminatory experiences based on potentially intersecting identities may be related to bladder health among women.

Psychosocial Factors Associated with Lower Urinary Tract Symptoms One Year Postpartum

Pregnancy carries substantial risk for developing lower urinary tract symptoms (LUTSs), with potential lifelong impacts on bladder health. Little is known about modifiable psychosocial factors that may influence the risk of postpartum LUTSs. We examined associations between depressive symptoms, perceived stress, and postpartum LUTSs, and the moderating effects of perceived social support, using data from a cohort study of Expect With Me group prenatal care (n = 462). One year postpartum, 40.3% participants reported one or more LUTS. The most frequent LUTS was daytime frequency (22.3%), followed by urinary incontinence (19.5%), urgency (18.0%), nocturia (15.6%), and bladder pain (6.9%). Higher odds of any LUTS were associated with greater depressive symptoms (adjusted odds ratio (AOR) 1.08, 95% confidence interval (CI) 1.04-1.11) and perceived stress (AOR 1.12, 95% CI 1.04-1.19). Higher perceived social support was associated with lower odds of any LUTS (AOR 0.94, 95% CI 0.88-0.99). Perceived social support mitigated the adverse effects of depressive symptoms (interaction AOR 0.99, 95% CI 0.98-0.99) and perceived stress (interaction AOR 0.97, 95% CI 0.95-0.99) on experiencing any LUTS. Greater depressive symptoms and perceived stress may increase the likelihood of experiencing LUTSs after childbirth. Efforts to promote bladder health among postpartum patients should consider psychological factors and social support.
