RESUMEN
BACKGROUND: Cognitive decline may progress for decades before dementia onset. Better cardiovascular health (CVH) has been related to less cognitive decline, but it is unclear whether this begins early, for all racial subgroups, and all domains of cognitive function. The purpose of this study was to determine the impact of CVH on decline in the 2 domains of cognition that decline first in White and Black women at midlife. METHODS AND RESULTS: Subjects were 363 Black and 402 White women, similar in baseline age (mean±SD, 46.6±3.0 years) and education (15.7±2.0 years), from the Chicago site of the Study of Women's Health Across the Nation. Cognition, measured as processing speed and working memory, was assessed annually or biennially over a maximum of 20 years (mean±SD, 9.8±6.7 years). CVH was measured as Life's Essential 8 (blood pressure, body mass index, glucose, non-high-density lipoprotein cholesterol, smoking, physical activity, diet, sleep). Hierarchical linear mixed models identified predictors of cognitive decline with progressive levels of adjustment. There was a decline in processing speed that was explained by race, age, and the 3-way interaction of race, CVH, and time (F1,4308=8.8, P=0.003). CVH was unrelated to decline in White women but in Black women poorer CVH was associated with greater decline. Working memory did not decline in the total cohort, by race, or by CVH. CONCLUSIONS: In midlife Black women, CVH promotion may be a target for preventing the beginnings of cognitive decline, thereby enhancing independent living with aging.

Background: Pelvic organ prolapse (POP) affects a considerable proportion of women. Limited information exists regarding the incidence of POP as women transition through menopause. Using data from the Study of Women's Health Across the Nation (SWAN), this diverse community-based longitudinal cohort study assessed the incidence of symptomatic POP and risk by race/ethnicity. Methods: Self-reported POP was ascertained by questionnaire at 11 approximately annual SWAN visits over a median of 13.3 years of follow-up. We estimated probabilities for reporting POP using interval-censored Kaplan-Meier survival plots. We estimated hazard ratios (HR) and 95% confidence intervals (CI) using interval-censored Cox proportional hazards models. Results: The estimated cumulative probability of POP increased linearly from 2.1% at age 45 to 10.1% by age 65 (4.0% per decade). At age 65, the probability was 4.2%, 4.8%, 8.9%, 9.7%, and 33.9% for Japanese, Chinese, Black, White, and Hispanic women, respectively. Compared with White women, the unadjusted HR for POP was 3.09 (95% CI = 2.18-4.39), 0.96 (0.71-1.31), 0.43 (0.22-0.85), and 0.48 (0.26-0.88) for Hispanic, Black, Chinese, and Japanese women, respectively. After adjustment for financial strain and vaginal birth, the low hazards among Chinese and Japanese women and the high hazard for Hispanic women remained significant. Conclusion: Incidence of symptomatic POP increased as women aged through midlife. Risks varied by race and ethnicity and were not accounted for by population differences in socioeconomic life contexts or the probability of having had a vaginal birth. Although not associated with menopause, health providers should incorporate screening for and information about POP when treating menopausal symptoms and health needs of midlife women. Research on pathophysiological factors associated with increasing POP in midlife is warranted.

OBJECTIVE: The aim of the study is to examine whether urinary incontinence (UI) type, frequency, and amount are associated with self-reported disability in a racially/ethnically diverse cohort of community-dwelling midlife women. METHODS: Data were from longitudinal analyses of questionnaires from the multicenter, prospective cohort Study of Women's Health Across the Nation (SWAN). We used multivariable ordinal logistic regression to examine whether urinary incontinence type, frequency, and amount at the 13th follow-up were associated with the World Health Organization Disability Assessment Schedule at the 15th follow-up controlling for other factors (menopause status, body mass index, lifestyle and psychosocial factors, and disability at follow-up 13). RESULTS: Urinary incontinence was associated with subsequent reports of disability in participants, particularly in the World Health Organization Disability Assessment Schedule domains of mobility ( P < 0.0001), communication ( P = 0.0057), and life activities ( P = 0.0407). Associations were strongest for mixed UI type compared with stress UI or urgency UI (odds ratio [OR] = 1.66, 95% confidence interval [CI] = 1.26-2.17, P < 0.001), daily frequency of UI compared with monthly or less than weekly frequency of UI (OR = 1.61, 95% CI = 1.04-2.47, P < 0.001), and larger amounts of urine leakage compared with drops of leakage (OR = 2.98, 95% CI = 1.58-5.62, P < 0.0001) for mobility/getting around domain. CONCLUSIONS: Urinary incontinence seems to have a strong association with multiple domains of disability, including mobility and interacting with others, after approximately 3.7 years. Thus, UI may be an important factor limiting social engagement among women. Screening for mixed UI and UI that occurs greater than weekly and in amounts requiring pads may yield better information regarding an individual's future disability risk and may preserve social interaction.

Physical function (PF) limitations are common in aging. However, there is a dearth of interventions focused on addressing PF limitations in community-based settings, particularly in minoritized communities. To guide intervention development, we conducted focus groups to understand perceptions of PF limitations, gauge intervention interest, and identify potential intervention strategies as part of a large health partnership of African American churches in Chicago, IL. Participants were age 40+ years with self-reported PF limitations. Focus groups (N=6 focus groups; N=40 participants) were audio recorded, transcribed, and analyzed using thematic analysis methods.Six themes were identified: (1) causes of PF limitations, (2) impact of PF limitations, (3) terminology and communication, (4) adaptations and treatments, (5) faith and resilience, and (6) prior program experiences. Participants described how PF limitations affected their ability to live a full life and play an active role in their family, church, and community. Faith and prayer aided in coping with limitations and pain. Participants expressed that it is important to keep moving, both from an emotional (not giving up) and physical (to prevent further exacerbation of limitations) standpoint. Some participants shared adaptation and modification strategies, but there were overall frustrations with communicating regarding PF limitations and obtaining medical care for them. Participants expressed that they would like to have programs in their church focused on improving PF (including physical activity), particularly as their communities often lacked resources conducive to being active. Community-based programs focusing on reducing PF limitations are needed, and the church is a potentially receptive setting.
RESUMEN
Objectives: Research has shown a link between childhood sexual abuse (CSA) and lower urinary tract and sexual disorders in clinical settings. We examined whether CSA was associated with two specific aspects of high tone, elevated resting tension pelvic floor dysfunction (PFD) in community-dwelling women. Materials and Methods: Data were from 2068 participants (25.5% Black, 9.6% Chinese, 10.8% Japanese, 5.0% Hispanic, and 49.1% Non-Hispanic White) in the Study of Women's Health Across the Nation (SWAN), a multirace/multiethnic longitudinal observational study of women's midlife health. At baseline, enrolled women were 42-52 years old and premenopausal or early perimenopausal. Annual or biennial assessments conducted over 20 years (1996 through 2017) included single-item queries about urgency urinary incontinence and pain with sexual activity used to assess PFD outcomes. The 12th follow-up visit conducted in 2009-2011 assessed the primary exposure, history of CSA, using a single-item response. Multivariate logistic regression models tested study objectives. Results: The prevalence of CSA was 15%, self-reported in 313/2068 women. CSA and PFD, both pain with sexual activity (odds ratio [OR] = 1.56 confidence interval [95% CI = 1.12-2.18]) and urgency urinary incontinence (OR = 1.87 [95% CI = 1.29-2.71]), were significantly associated in unadjusted models. The final adjusted model that included sociodemographic variables and physical and behavioral risk factors was significant for pain with sexual activity (OR = 1.48 [95% CI = 1.08-2.02]), but not for urgency urinary incontinence (OR = 1.38 [95% CI = 0.96-1.98]). Conclusions: In midlife women, pain with sex, but not urgency urinary incontinence, was associated with a history of CSA. A multidisciplinary diagnostic and therapeutic approach to PFD is key, inclusive of CSA screening.

OBJECTIVES: To determine whether physical function (PF) before menopause is related to cardiovascular disease (CVD) risk. METHODS: Participants were N = 2950 pre-/early peri-menopausal women (median age 46, (25th-75th percentile: 43-48 years). Physical function was assessed at baseline using the Physical Function subscale of the SF-36 and scores were trichotomized (no, some, or substantial limitations). Clinical CVD events were ascertained at annual/biennial clinical assessments through the 15th follow-up visit. Risk of CVD was determined with Cox proportional hazards models. Results: Women were followed for a median of 19.1 years, during which 220 women had a CVD event. In fully adjusted models, women with substantial limitations at baseline had higher CVD risk compared to women with no limitations (hazards ratio [HR] = 1.55, 95% confidence interval [CI]: 1.12-2.33). Discussion: Substantial PF limitations in pre- and early peri-menopausal women are associated with higher risk of clinical CVD events, consistent with literature in older adults.

OBJECTIVE: To examine whether patterns of sexual intercourse frequency and demographic, menopausal status, genitourinary, health, and psychosocial factors are associated with developing sexual pain across the menopausal transition. METHODS: These were longitudinal analyses of questionnaire data from the multicenter, multiracial and ethnic prospective cohort SWAN (Study of Women's Health Across the Nation) (1995-2008). We used multivariable discrete-time proportional hazards models to examine whether incident sexual pain was associated with preceding long-term (up to 10 visits) or short-term (two and three visits) sexual intercourse frequency patterns or other factors (eg, menopause status, genitourinary symptoms, lifestyle factors, and mental health). RESULTS: Of the 2,247 women with no sexual pain at baseline, 1,087 (48.4%) developed sexual pain at least "sometimes" up to 10 follow-up visits over 13 years. We found no consistent association between prior patterns of sexual intercourse frequency and development of sexual pain. For example, neither decreases in intercourse frequency from baseline (adjusted hazard ratio [aHR] 0.93, 95% CI 0.73-1.19) nor decreases in frequency over three prior visits (aHR 1.00, 95% CI 0.72-1.41) were associated with incident pain. Reasons for interruptions in intercourse activity at the prior visit, including lack of interest (aHR 1.64, 95% CI 0.74-3.65) and relationship issues (aHR 0.36, 95% CI 0.04-2.88), were not associated with developing pain. Being postmenopausal using hormone therapy (aHR 3.16, 95% CI 1.46-6.85), and reported vaginal dryness (aHR 3.73, 95% CI 2.88-4.83) were most strongly associated with incident sexual pain. CONCLUSION: Long-term and short-term declines in sexual intercourse frequency across the menopausal transition were not associated with increased hazard of developing pain with intercourse. This empirical evidence does not support the common belief that a reduction in women's sexual frequency is responsible for their symptoms of sexual pain.

ABSTRACT: Athletes are vulnerable to sexual violence. Perpetrators of sexual violence may be a trusted coach, a member of the health care team, or a peer. The consequences of sexual violence are wide ranging, resulting in immediate and long-term physical and mental health outcomes that require recognition and comprehensive, multidisciplinary care. Sports medicine providers need to have specific knowledge and skill to care for athletes who experience sexual violence. Several sports organizations (e.g., International Olympic Committee, United States Olympic and Paralympic Committee, the National Collegiate Athletic Association, and the National Athletic Trainers' Association) have developed policies and procedures to prevent sexual violence and help sports medicine specialists provide care and services for athletes affected by sexual violence. Nevertheless, there remains a need for clinical guidelines, screening tools, and education, as well as clinical best practices to address sexual violence in sports medicine.

To determine the cross-sectional associations of accelerometer-measured time spent in physical activity intensity categories (sedentary, low and high light intensity, or moderate to vigorous intensity physical activity (MVPA) with physical performance outcomes [stair climb ascent, 40 foot walk test, and short physical performance battery (SPPB)] in older women and examine differences by race/ethnicity. Data were from 1,256 Study of Women's Health Across the Nation (SWAN) participants [aged 64.9 (2.7) years at Visit 15 (2015-16); 54.1% non-White]. Three sets of adjusted multivariable linear or logistic regression models were built to test the study objectives using the backward elimination approach to identify relevant covariates. In the full analytic sample, a 10 min increment in MVPA was related to faster performance on the stair climb [ß = -0.023 (95% CI: -0.04, -0.005) seconds] and 40 foot walk test [ß = -0.066 (95% CI: -0.133, -0.038) seconds], and a 9% lower odds [OR: 0.91; 95% CI: 0.87, 0.96; p = 0.004] of limitations based on the SPPB. Statistically significant differences by race/ethnicity were found for the stair climb ascent time as MVPA was associated with better performance for White, Chinese, and Japanese participants while high light intensity physical activity, but not MVPA, was deemed beneficial in Black women. Findings from the isotemporal substitution models were consistent. Findings further support the importance of MVPA on physical performance outcomes in older women. Further research is needed to examine the complex associations between physical (in)activity and physical performance outcomes by race/ethnicity to provide more targeted recommendations.
RESUMEN
INTRODUCTION: Limitations in physical function are predictive of adverse health outcomes, and screening has been recommended in clinical settings for older adults. Rarely assessed in community-based settings, physical function could provide insight for tailoring health-related community-based programs and raise awareness about this important aspect of health. This cross-sectional study seeks to demonstrate the feasibility of integrating physical function assessments into health screenings in African American churches in Chicago, Illinois, through a large health partnership and to determine the prevalence and correlates of physical function limitations among midlife (aged 40-59 years) and late-life (aged ≥60 years) participants. METHODS: Screenings were held in 7 churches in Spring 2018. Physical function was assessed using the Short Physical Performance Battery. Demographics, medical history, health status, and health behaviors were assessed. Age-stratified logistic regression identified independent associations with physical function limitations (Score ≤9) among midlife and late-life participants (data were analyzed in 2018-2019). RESULTS: Among 731 participants (median age=57 [IQR=51-65] years, 58% women, 97% African American), 25% of midlife and 56% of late-life participants had physical function limitations. For midlife participants, fair/poor health (OR=1.83, 95% CI=1.10, 3.05), stroke/neurologic conditions (OR=2.42, 95% CI=1.07, 5.46), and arthritis (OR=2.25, 95% CI=1.32, 3.81) were associated with higher odds of limitations. Fair/poor health (OR=1.97, 95% CI=1.11, 3.50) and stroke/neurologic conditions (OR=7.85, 95% CI=2.22, 27.74) were related to limitations among late-life participants. CONCLUSIONS: Physical function screening was successfully implemented into this large-scale church-based health screening program. Physical function limitations were prevalent, particularly at midlife; this information will be used to guide future programs.

OBJECTIVE: This study aimed to assess the characteristics of patients assessed and treated at a multidisciplinary pelvic floor program that includes representatives from multiple specialties. Our goal is to describe the process from triaging patients to the actual collaborative delivery of care. This study examines the factors contributing to the success of our multidisciplinary clinic as evidenced by its ongoing viability. METHODS: This is a descriptive study retrospectively analyzing a prospectively maintained database that included the first 100 patients seen in the Program for Abdominal and Pelvic Health clinic between December 2017 and October 2018. We examined patient demographics, their concerns, and care plan including diagnostic tests, findings, treatments, referrals, and return visits. RESULTS: The clinic met twice monthly, and the first 100 patients were seen over the course of 10 months. The most common primary symptoms were pelvic pain (45), constipation (30), bladder incontinence (27), bowel incontinence (23), high tone pelvic floor dysfunction (23), and abdominal pain (23); most patients had more than one presenting symptom (76). The most common specialties seen at the first visit to the clinic included gastroenterology (56%), followed by physical medicine and rehabilitation (45%), physical therapy (31%), female pelvic medicine and reconstructive surgery (25%), behavioral health (19%), urology (18%), and colorectal surgery (13%). Eleven patients were entirely new to our hospital system. Most patients had diagnostic tests ordered and performed. CONCLUSIONS: A multidisciplinary clinic for abdominal and pelvic health proves a sustainable model for comprehensive treatment for patients with pelvic floor dysfunction, including difficulties with defecation, urination, sexual dysfunction, and pain.

BACKGROUND: Chronic conditions are associated with worse physical function and commonly develop during midlife. We tested whether the presence of 8 chronic conditions, or the development of these conditions, is associated with declines in physical function among midlife women as they transition into early late life. METHODS: Participants (N = 2283) were from the Study of Women's Health Across the Nation. Physical function was assessed at 8 visits starting at the study's fourth clinic visit in 2000/2001 through follow-up visit 15 (2015/2017) using the Short Form-36 Physical Function subscale. Chronic conditions included diabetes, hypertension, osteoarthritis, osteoporosis, stroke, heart disease, cancer, and depressive symptoms. Repeated-measures Poisson regression modeled associations between 1) prevalent chronic conditions at analytic baseline (visit 4) and longitudinal physical function, and 2) change in physical function associated with developing a new condition. Models were adjusted with the total number of other chronic conditions at visit 4. RESULTS: In separate fully-adjusted longitudinal models, prevalent heart disease and osteoporosis were associated with 18% (IRR = 0.815, 95% confidence interval [CI]: 0.755-0.876) and 12% (IRR = 0.876, 95% CI: 0.825-0.927) worse initial physical function, respectively. Prevalent osteoarthritis was associated with approximately 6% (IRR = 0.936, 95% CI: 0.913-0.958) worse initial physical function, and a slight additional worsening over time (IRR = 0.995, 95% CI: 0.994-0.996). A 12% (IRR = 0.878, 95% CI: 0.813-0.950) decrease in physical function concurrent with stroke development was evident, as was accelerated decline in physical function concurrent with heart disease development (IRR = 0.991, 95% CI: 0.988-0.995). CONCLUSIONS: Initial prevalent conditions related to the musculoskeletal system were associated with worse initial physical function, with some evidence of accelerated decline in physical function with osteoarthritis. Stroke and heart disease are less common than osteoarthritis in this age group, but the severe effects of these conditions on physical function shows the need for a greater focus on cardiovascular health during midlife. Women who develop chronic conditions during midlife may be at particular risk for poor physical function as they age, warranting disability prevention efforts focused on this population.

West Side Alive (WSA) is a partnership among pastors, church members and health researchers with the goal of improving health in the churches and surrounding community in the West Side of Chicago, a highly segregated African American area of Chicago with high rates of premature mortality and social disadvantage. To inform health intervention development, WSA conducted a series of health screenings that took place in seven partner churches. Key measures included social determinants of health and healthcare access, depression and PTSD screeners, and measurement of cardiometabolic risk factors, including blood pressure, weight, cholesterol and hemoglobin A1C (A1C). A total of 1106 adults were screened, consisting of WSA church members (n = 687), members of the local community served by the church (n = 339) and 80 individuals with unknown church status. Mean age was 52.8 years, 57% were female, and 67% reported at least one social risk factor (e.g. food insecurity). Almost all participants had at least one cardiovascular risk factor (92%), including 50% with obesity, 79% with elevated blood pressure and 65% with elevated A1C. A third of participants experienced ≥ 4 potentially traumatic events and 26% screened positive for depression and/or post-traumatic stress disorder. Participants were given personalized health reports and referred to services as needed. Information from the screenings will be used to inform the design of interventions targeting the West Side community and delivered in partnership with the churches. Sharing these results helped mobilize community members to improve their own health and the health of their community.

OBJECTIVES: Evaluate degree to which racial/ethnic differences in physical performance are mediated by sociodemographic, health, behavioral, and psychosocial factors. METHODS: Physical performance was evaluated using a decile score derived from grip strength, timed 4 m walk, and timed repeat chair stand in 1,855 African American, Caucasian, Chinese, Hispanic, and Japanese women, mean age = 61.8 (SD = 2.7) in the Study of Women's Health Across the Nation. Mediators included education, financial strain, comorbidities, pain, body mass index (BMI), physical activity, and perceived stress. Structural equation models provided estimates of the total difference in physical performance between Caucasians and each race/ethnic groups and differences due to direct effects of race/ethnicity and indirect effects through mediators. RESULTS: The mean decile score for Caucasian women was 16.9 (SD = 5.6), 1.8, 2.6, and 2.1 points higher than the model-estimated scores in African Americans, Hispanics and Chinese, respectively, and 1.3 points lower than the Japanese. Differences between Caucasians and the Chinese and Japanese were direct effects of race/ethnicity whereas in African Americans and Hispanics 75% or more of that disparity was through mediators, particularly education, financial strain, BMI, physical activity, and pain. DISCUSSION: Addressing issues of poverty, racial inequality, pain, and obesity could reduce some racial/ethnic disparity in functional limitations as women age.

BACKGROUND: Body composition strongly influences physical function in older adults. Bioelectrical impedance analysis (BIA) differentiates fat mass from skeletal muscle mass, and may be more useful than body mass index (BMI) for classifying women on their likelihood of physical function impairment. AIMS: This study tested whether BIA-derived estimates of percentage body fat (%BF) and height-normalized skeletal muscle mass (skeletal muscle mass index; SMI) enhance classification of physical function impairment relative to BMI. METHOD: Black, White, Chinese, and Japanese midlife women (N = 1482) in the Study of Women's Health Across the Nation (SWAN) completed performance-based measures of physical function. BMI (kg/m2) was calculated. %BF and SMI were derived through BIA. Receiver-operating characteristic (ROC) curve analysis, conducted in the overall sample and stratified by racial group, evaluated optimal cutpoints of BMI, %BF, and SMI for classifying women on moderate-severe physical function impairment. RESULTS: In the overall sample, a BMI cutpoint of ≥ 30.1 kg/m2 correctly classified 71.1% of women on physical function impairment, and optimal cutpoints for %BF (≥ 43.4%) and SMI (≥ 8.1 kg/m2) correctly classified 69% and 62% of women, respectively. SMI did not meaningfully enhanced classification relative to BMI (change in area under the ROC curve = 0.002; net reclassification improvement = 0.021; integrated discrimination improvement = - 0.003). Optimal cutpoints for BMI, %BF, and SMI varied substantially across race. Among Black women, a %BF cutpoint of 43.9% performed somewhat better than BMI (change in area under the ROC curve = 0.017; sensitivity = 0.69, specificity = 0.64). CONCLUSION: Some race-specific BMI and %BF cutpoints have moderate utility for identifying impaired physical function among midlife women.

BACKGROUND: Chronic medical conditions (CMCs) often emerge and accumulate during the transition from mid- to late-life, and the resulting multimorbidity can greatly impact physical function. We assessed the association of CMC presence and incidence on trajectories of physical function from mid- to early late-life in the Study of Women's Health Across the Nation. METHODS: Physical function was assessed at eight clinic visits (average 14 years follow-up) using the physical function subscale of the Short Form-36. CMCs included osteoarthritis, diabetes, stroke, hypertension, heart disease, cancer, osteoporosis, and depressive symptomatology, and were considered cumulatively. Repeated-measures Poisson models estimated longitudinal change (expressed as percent difference) in physical function by chronic CMCs. Change-points assessed physical function change coincident with the development of a new condition. RESULTS: Women (N = 2,283) followed from age 50.0 ± 2.7 to 64.0 ± 3.7 years; 7.3% had zero CMCs through follow-up, 22.5% (N = 513) had no baseline CMCs but developed ≥1, 22.7% women had ≥1 baseline CMC but never developed another, and 47.6% had ≥1 baseline CMC and developed ≥1 more. Each additional baseline CMC was associated with 4.0% worse baseline physical function and annual decline of 0.20%/year. Women with more baseline CMCs had greater decline in physical function with a new CMC (-1.90% per condition); and annual decline when developing a new condition accelerated by -0.33%/year per condition. CONCLUSIONS: Self-reported physical function changes are evident from mid- to early late-life with the development of CMCs. Preventing or delaying CMCs may delay declines in physical function, and these potential pathways to disability warrant further research.
