BACKGROUND AND AIMS:Previous community-based studies have demonstrated sex and race-based disparities in the risk of cardiovascular disease. We sought to examine the association of sex and race with incident peripheral artery disease (PAD-) and critical limb ischemia (CLI-) related hospitalizations. METHODS:In 13,451 Black and White ARIC participants without prevalent PAD at baseline (1987-89), we estimated the cumulative incidence of PAD- and CLI-related hospitalization over a median follow-up of 26 years. We quantified hazard ratios (HRs) using Cox models across four sex- and race-groups. PAD and CLI were defined by hospitalization discharge codes. RESULTS:The cumulative incidence of PAD-related hospitalization was higher in males than females in Whites (5.1% vs. 2.7%; p<0.001) but not in Blacks (5.7% vs. 5.0%; p=0.39). The cumulative incidence of CLI-related hospitalization differed significantly by race more than sex, occurring in 3.1% Black males, 3.1% Black females, 1.4% White males, and 0.8% White females (p<0.001). After risk factor adjustment, the risk of incident PAD-related hospitalization was similar for White males vs. White females [HR 1.14, 95%CI 0.90-1.45], and slightly higher for Black males [HR 1.26, 95%CI 0.92-1.72] and Black females [HR 1.39, 95%CI 1.03-1.87] compared to White females. The adjusted risk of incident CLI-related hospitalization was similar for White males vs. White females [HR 1.15, 95%CI 0.75-1.76], and significantly higher for Black males [HR 1.96, 95%CI 1.22-3.16] and Black females [HR 2.06, 95%CI 1.31-3.24] compared to White females. CONCLUSIONS:These data suggest that there are both sex- and race-specific patterns of PAD-related hospitalization that lead to differences in clinical disease risk and presentation.

BACKGROUND:For people with advanced stage cystic fibrosis (CF), tailored survival estimates could facilitate preparation for decision-making in the event of acutely deteriorating respiratory function. METHODS:We used the US CF Foundation national database (2008-2013) to identify adult people with incident advanced stage CF (forced expiratory volume in 1 s (FEV1) ≤45% predicted). Using the lasso method for variable selection, we divided the dataset into training and validation samples (2:1), and developed two multivariable Cox proportional hazards models to calculate probabilities of survival from baseline (T0 model), and from 1 year after (T12 model). We also performed Kaplan-Meier survival analyses. RESULTS:colonisation; cirrhosis; depression; dialysis; current smoking; unclassifiable mutation class and cumulative CF exacerbations predicted increased mortality. Baseline transplant evaluation status of 'accepted, on waiting list' predicted decreased mortality. For the T12 model, interim decrease in FEV1 >10%, and pulmonary exacerbations additionally increased predicted mortality. Lung transplantation was associated with lower mortality. Of the 4752, 93.5%, 86.4%, 79.7% and 73.9% survived to 1, 2, 3 and 4 years, respectively, without considering any confounding variables. The models had moderate predictive ability indicated by the area under the time-dependent receiver operating characteristic curve (0.787, 95% CI 0.769 to 0.794 for T0 model; and 0.779, 95% CI 0.767 to 0.797 for T12 model). CONCLUSION/CONCLUSIONS:We have developed models predicting survival in people with incident advanced stage CF, which can be reapplied over time to support shared decision-making about end-of-life treatment choices and lung transplantation. These estimates must be updated as data become available regarding long-term outcomes for people treated with CF transmembrane conductance regulator modulators.

BACKGROUND:Adults age ≥ 50 are among the fastest growing populations in correctional supervision and are medically underserved while experiencing unique health disparities. Community-living older adults, referred to as "justice-involved," are people who have been recently arrested, or are on probation or parole. Although medical complexity is common among incarcerated older adults, the occurrence of medical morbidity, substance use disorder (SUD), and mental illness among justice-involved older adults living in US communities is poorly understood. OBJECTIVE:To estimate the prevalence of medical multimorbidity (≥ 2 chronic medical diseases), SUDs, and mental illness among justice-involved adults age ≥ 50, and the co-occurrence of these conditions. DESIGN/METHODS:Cross-sectional analysis. PARTICIPANTS/METHODS:A total of 34,898 adults age ≥ 50 from the 2015 to 2018 administrations of the US National Survey on Drug Use and Health. MAIN MEASURES/METHODS:Demographic characteristics of justice-involved adults age ≥ 50 were compared with those not justice-involved. We estimated prevalence of mental illness, chronic medical diseases, and SUD among adults age ≥ 50 reporting past-year criminal justice system involvement. Logistic regression was used to estimate the odds of these conditions and co-occurrence of conditions, comparing justice-involved to non-justice-involved adults. KEY RESULTS/RESULTS:An estimated 1.2% (95% confidence interval [CI] = 1.1-1.3) of adults age > 50 experienced criminal justice involvement in the past year. Compared with non-justice-involved adults, justice-involved adults were at increased odds for mental illness (adjusted odds ratio [aOR] = 3.04, 95% CI = 2.09-4.41) and SUD (aOR = 8.10, 95% CI = 6.12-10.73), but not medical multimorbidity (aOR = 1.15, 95% CI = 0.85-1.56). Justice-involved adults were also at increased odds for all combinations of the three outcomes, including having all three simultaneously (aOR = 8.56, 95% CI = 4.10-17.86). CONCLUSIONS:Community-based middle-aged and older adults involved in the criminal justice system are at high risk for experiencing co-occurring medical multimorbidity, mental illness, and SUD. Interventions that address all three social and medical risk factors are needed for this population.

BACKGROUND AND AIMS/OBJECTIVE:Three to ten minutes of smoking cessation advice by physicians is effective to increase quit rates but not routinely practised. We examined the effectiveness of physicians' very brief (about 30 seconds) smoking cessation intervention on quit rates among Chinese outpatient smokers. DESIGN/METHODS:A pragmatic, open-label, individually randomized controlled trial. SETTING/METHODS:Seventy-two medical outpatient departments of hospitals and/or community health centers in Guangdong, China. PARTICIPANTS/METHODS:Chinese adults who were daily cigarette smokers (N = 13,671, 99% males) were invited by their physician to participate during outpatient consultation. Smokers who were receiving smoking cessation treatment or were judged to needed specialist treatment for cessation were excluded. INTERVENTIONS/METHODS:The intervention group (n = 7,015) received a 30-second intervention including physician's very brief advice, a leaflet with graphic warnings, and a card with contact information of available cessation services. The control group (n = 6,656) received a very brief intervention on consuming vegetables and fruits. A total of 3,466 participants in the intervention group were further randomized to receive a brief booster advice from trained study personnel through telephone one month following their doctor visit. MEASUREMENTS/METHODS:The primary outcome was self-reported 7-day point prevalence abstinence in the intervention and control group at the 12-month follow-up. Secondary outcomes included self-reported 30-day abstinence and biochemically validated abstinence at 12-month follow-up. FINDINGS/RESULTS:By intention-to-treat, the intervention (vs. control) group had greater self-reported 7-day abstinence (9.1% vs. 7.8%; odds ratio (OR) 1.14; 95% Confidence Interval (CI) 1.03-1.26; P = .008) and 30-day abstinence (8.0% vs. 6.9%; OR 1.14 95% CI 1.03-1.27; P=0.01) at 12-month follow-up. The effect size increased when only participants who received the intervention from compliant physicians were included (7-day PPA OR = 1.42; 1.11-1.74). The group difference in biochemically validated abstinence was small (0.8% vs. 0.8%; OR 1.00 95% CI 0.71-1.42; P=0.99). CONCLUSION/CONCLUSIONS:A 30-second smoking cessation intervention increased self-reported abstinence among mainly male smokers in China at 12-month follow-up (risk difference = 1.3%) and should be feasible to provide in most settings and delivered by all healthcare professionals.

OBJECTIVE:To evaluate the association of premature atrial contraction (PAC) frequency with cognitive test scores and prevalence of dementia or mild cognitive impairment (MCI). MATERIALS AND METHODS:We conducted a cross-sectional analysis using Atherosclerosis Risk in Communities study visit 6 (January 1, 2016, through December 31, 2017) data. We included 2163 participants without atrial fibrillation (AF) (age mean ± SD, 79±4 years; 1273 (58.9%) female; and 604 (27.97.0% Black) who underwent cognitive testing and wore a leadless, ambulatory electrocardiogram monitor for 14 days. We categorized PAC frequency based on the percent of beats: less than 1%, minimal; 1% to <5%, occasional; greater than or equal to 5%, frequent. We derived cognitive domain-specific factor scores (memory, executive function, language, and global z-score). Dementia and MCI were adjudicated. RESULTS:During a mean analyzable time of 12.6±2.6 days, 339 (15.7%) had occasional PACs and 107 (4.9%) had frequent PACs. Individuals with frequent PACs (vs minimal) had lower executive function factor scores by 0.30 (95% CI, -0.46 to -0.14) and lower global factor scores by 0.20 (95% CI, -0.33 to -0.07) after multivariable adjustment. Individuals with frequent PACs (vs minimal) had higher odds of prevalent dementia or MCI after multivariable adjustment (odds ratio, 1.74; 95% CI, 1.09 to 2.79). These associations were unchanged with additional adjustment for stroke. CONCLUSION:In community-dwelling older adults without AF, frequent PACs were cross-sectionally associated with lower executive and global cognitive function and greater prevalence of dementia or MCI, independently of stroke. Our findings lend support to the notion that atrial cardiomyopathy may be a driver of AF-related outcomes. Further research to confirm these associations prospectively and to elucidate underlying mechanisms is warranted.

BACKGROUND AND OBJECTIVES/OBJECTIVE:Children who become overweight by age 2 have greater risk of long-term obesity and health problems. The study aim was to assess the effectiveness of a primary care-based intervention on the prevalence of overweight at age 24 months. METHODS:score). RESULTS:score differences (treatment minus control) were -0.04 (95% CI: -0.07 to -0.01), -0.09 (95% CI: -0.14 to -0.03), -0.19 (-0.33 to -0.05), -0.20 (-0.36 to -0.03), -0.16 (95% CI: -0.34 to 0.01), and 0.00 (95% CI -0.21 to 0.21) at 4, 6, 12, 15, 18, and 24 months, respectively. CONCLUSIONS:The intervention resulted in less weight gain through age 18 months, which was not sustained through 24 months. Clinic-based interventions may be beneficial for early weight gain, but greater intervention intensity may be needed to maintain positive effects.

Objectives: Sexual health is an important component of overall health and well-being for older adults. Despite this, little is known about the importance of sex to quality of life, as part of romantic relationships for older adults, and potential drivers of interactions between healthcare providers and older adults about sexual health. In this study using a nationally representative population, we describe perceptions and experiences of sex among older adults.Methods: A nationally representative, cross-sectional sample of community-dwelling U.S. adults aged 65-80 was surveyed about their sexual health and interaction with their health care providers about sexual health.Results: The survey completion rate was 75% (N = 1,002). Overall, 50.9% of men and 30.8% of women reported being sexually active. In all, 17.3% of adults aged 65-80 reported speaking to their health care provider about sexual health in the past two years and of those, 60.5% of patients initiated the conversation. Multivariable logistic regression demonstrated that sexual activity (yes/no), interest in sex, and satisfaction with sex life are major drivers of sexual health conversations between patients and healthcare providers.Conclusions: Many adults aged 65-80 are interested in and engage in sexual activity. While the majority of older adults reported a willingness to discuss their sexual health with their health care providers, few had done so, and most conversations were initiated by patients. Iterest in sex and satisfaction with sex life may be targets for intervention and offer a segue for providers as they begin the conversation to engage with older adults about their sexual health.Clinical Implications: Providers may have conversations with older adults about sexual health and may need sexual health training to have effective discussions; age nor chronic conditions should preclude this essential conversation. Clinical gerontologists may be helpful in this training and in encouraging patients to bring up sexual health concerns during their medical appointments.

PURPOSE/OBJECTIVE:To characterize the demographic differences between infertile/sub-fertile women who utilized infertility services vs. those that do not. METHODS:A retrospective analysis of cross-sectional data obtained during the 2011-2013, 2013-2015, and 2015-2017 cycles of National Survey for Family Growth from interviews administered in home for randomly selected participants by a National Center of Health Statistics (NCHS) surveyor was used to analyze married, divorced, or women with long-term partners who reported difficulty having biological children (sub-fertile/infertile women). Demographic differences such as formal marital status, education, race, and religion were compared between women who presented for infertility care vs. those that did not. The primary outcome measure was presenting for infertility evaluation and subsequently utilizing infertility services. Healthcare utilization trends such as having a usual place of care and insurance status were also included as exposures of interest in the analysis. RESULTS:Of the 12,456 women included in the analysis 1770 (15.3%) had used infertility services and 1011 (8.3%) said it would be difficult for them to have a child but had not accessed infertility services. On univariate analysis, compared to women who used infertility services, untreated women had lower average household incomes (295.3 vs. 229.8% of the federal poverty line respectively). Untreated women also had lower levels of education and were more likely to be divorced or never have married. In terms of health status, unevaluated women were less likely to have a usual place for healthcare (87.3%) as compared to women presenting for fertility care (91.9%) (p = 0.004). When examining insurance status, 23.3% of unevaluated women were uninsured as compared to 8.3% of evaluated women. On multivariate analysis, infertile women without insurance were at 0.37 odds of utilizing infertility care compared to women with insurance. CONCLUSIONS:Demographic factors are associated with the utilization of infertility care. Insurance status is a significant predictor of whether or not infertile women will access treatment. Data from the three most recent NSFG surveys along with prior analyses demonstrate the need for expanded insurance coverage in order to address the socioeconomic disparities between infertile women who are accessing services vs. those that are not.
