Group-based Education and monitoring program delivered by community health workers to improve control of high blood pressure in island districts of lake victoria, Uganda.

BACKGROUND: Individuals living in communities with poor access to healthcare may be unaware of their high blood pressure (BP). While the use of community health workers (CHWs) can address gaps in human resources for health, CHWs in Uganda have not been used previously for BP screening and management. We report the results of an initiative to train CHWs to evaluate BP and to administer group-based education in Kalangala and Buvuma Island Districts of Lake Victoria, Uganda. METHODS: We randomly selected 42 of 212 villages. We trained CHWs based in island districts on measuring BP. CHWs visited all households in the selected villages and invited all adults ≥ 18 years to be screened for high BP. We used the World Health Organization's STEPwise tool to collect data on demographic and behavioral characteristics and BP measurements. High blood pressure was defined as systolic BP (SBP) ≥ 140 mm Hg and/or diastolic BP (DBP) ≥ 90 mm Hg over three readings. CHWs created and led fortnight support groups for individuals identified with high blood pressure at baseline. At each group meeting, CHWs re-measured BP and administered an intervention package, which included self-management and lifestyle education to participants. The paired t-test was used to compare mean values of systolic blood pressure (SBP) and diastolic blood pressure (DBP) before and after the intervention. Generalized estimating equations (GEE) were used to model longitudinal changes in BP. RESULTS: We trained 84 CHWs to measure BP and deliver the intervention package. Among 2,016 community members, 570 (28.3%) had high blood pressure; of these, 63 (11.1%) had a previous diagnosis of hypertension. The comparison of SBP and DBP before and after the intervention revealed significant reductions in mean SBP from 158mmHg (SD = 29.8) to 149 mmHg (SD = 29.8) (p < 0.001) and mean DBP from 97mmHg (SD = 14.3) to 92mmHg (p < 0.001). GEE showed decreases of -1.133 (SBP) and - 0.543 mmHg (DBP)/fortnight. CONCLUSION: High BP was common but previously undiagnosed. The CHW-led group-based self-management and education for controlling high BP was effective in the island districts in Uganda. Scaling up the intervention in other hard-to-reach districts could improve control of high BP on a large scale.

Prevalence of Stroke - Behavioral Risk Factor Surveillance System, United States, 2011-2022.

Stroke was the fifth leading cause of death in the United States in 2021, and cost U.S. residents approximately $56.2 billion during 2019-2020. During 2006-2010, self-reported stroke prevalence among noninstitutionalized adults had a relative decrease of 3.7%. Data from the Behavioral Risk Factor Surveillance System were used to analyze age-standardized stroke prevalence during 2011-2022 among adults aged ≥18 years. From 2011-2013 to 2020-2022, overall self-reported stroke prevalence increased by 7.8% nationwide. Increases occurred among adults aged 18-64 years; females and males; non-Hispanic Black or African American (Black), non-Hispanic White (White), and Hispanic or Latino (Hispanic) persons; and adults with less than a college degree. Stroke prevalence was higher among adults aged ≥65 years than among younger adults; among non-Hispanic American Indian or Alaska Native, non-Hispanic Native Hawaiian or Pacific Islander, and Black adults than among White adults; and among adults with less than a high school education than among those with higher levels of education. Stroke prevalence decreased in the District of Columbia and increased in 10 states. Initiatives to promote knowledge of the signs and symptoms of stroke, and the identification of disparities in stroke prevalence, might help to focus clinical and programmatic interventions, such as the Million Hearts 2027 initiative or the Paul Coverdell National Acute Stroke Program, to improve prevention and treatment of stroke.

Prevalence of Self-Reported Hypertension and Antihypertensive Medication Use Among Adults - United States, 2017-2021.

Hypertension, or high blood pressure, is a major risk factor for heart disease and stroke. It increases with age and is highest among non-Hispanic Black or African American persons, men, persons aged ≥65 years, those of lower socioeconomic status, and those who live in the southern United States. Hypertension affects approximately one half of U.S. adults, and approximately one quarter of those persons have their blood pressure under control. Reducing population-level hypertension prevalence and improving control is a national priority. In 2017, updated guidelines for high blood pressure in adults recommended lowering the blood pressure threshold for diagnosis of hypertension. Analysis of data from the Behavioral Risk Factor Surveillance System found that age-standardized, self-reported diagnosed hypertension was approximately 30% during 2017-2021, with persistent differences by age, sex, race and ethnicity, level of education, and state of residence. During this period, the age-standardized prevalence of antihypertensive medication use among persons with hypertension increased by 3.1 percentage points, from 59.8% to 62.9% (p<0.001). Increases in antihypertensive medication use were observed in most sociodemographic groups and in many states. Assessing current trends in hypertension diagnosis and treatment can help guide the development of policies and implementation of interventions to reduce this important risk factor for cardiovascular disease and can aid in addressing health disparities.

Changes in Self-Measured Blood Pressure Monitoring Use in 14 States From 2019 to 2021: Impact of the COVID-19 Pandemic.

BACKGROUND: Self-measured blood pressure monitoring (SMBP) is an important out-of-office resource that is effective in improving hypertension control. Changes in SMBP use during the Coronavirus Disease 2019 (COVID-19) pandemic have not been described previously. METHODS: Behavioral Risk Factor Surveillance System (BRFSS) data were used to quantify changes in SMBP use between 2019 (prior COVID-19 pandemic) and 2021 (during the COVID-19 pandemic). Fourteen states administered the SMBP module in both years. All data were self-reported from adults who participated in the BRFSS survey. We assessed the receipt of SMBP recommendations from healthcare professionals and actual use of SMBP among those with hypertension (n = 68,820). Among those who used SMBP, we assessed SMBP use at home and sharing BP readings electronically with healthcare professionals. RESULTS: Among adults with hypertension, there was no significant changes between 2019 and 2021 in those reporting SMBP use (57.0% vs. 55.7%) or receiving recommendations from healthcare professionals to use SMBP (66.4% vs. 66.8%). However, among those who used SMBP, there were significant increases in use at home (87.7% vs. 93.5%) and sharing BP readings electronically (8.6% vs. 13.1%) from 2019 to 2021. Differences were noted by demographic characteristics and residence state. CONCLUSIONS: Receiving a recommendation from the healthcare provider to use SMBP and actual use did not differ before and during the COVID-19 pandemic. However, among those who used SMBP, home use and sharing BP readings electronically with healthcare professional increased significantly, although overall sharing remained low (13.1%). Maximizing advances in virtual connections between clinical and community settings should be leveraged for improved hypertension management.

Relationship Between Ultra-Processed and Minimally Processed Food Intake and Cardiovascular Health Among US Women of Reproductive Age.

Objectives: Ultra-processed food (UPF) intake is associated with worse cardiovascular health (CVH), but associations between unprocessed/minimally processed foods (MPFs) and CVH are limited, especially among women of reproductive age (WRA). Materials and Methods: For 5,773 WRA (20-44 years) in National Health and Nutrition Examination Survey (NHANES) 2007-2018, we identified UPFs and MPFs using the Nova classification and based on 24-hour dietary recalls. We calculated usual percentages of calories from UPFs and MPFs using the National Cancer Institute's usual intake method. Seven CVH metrics were scored, and CVH levels were grouped by tertile. We used multivariable linear and multinomial logistic regression to assess associations between UPFs and MPFs and CVH. Results: The average usual percentage of calories from UPFs and MPFs was 57.2% and 29.3%, respectively. There was a graded, positive association between higher UPF intake and higher odds of poor CVH: adjusted odds ratios (aORs) for the lowest versus highest CVH were 1.74 (95% confidence interval: 1.51-2.01), 2.67 (2.07-3.44) and 4.66 (3.13-6.97), respectively, comparing quartile 2 (Q2)-Q4 to the lowest quartile (Q1) of UPF intake. Higher MPF intake was associated with lower odds of poor CVH: aORs for the lowest CVH were 0.61 (0.54-0.69), 0.39 (0.31-0.50), and 0.21 (0.14-0.31). Patterns of association remained consistent across subgroups and in sensitivity analyses. Conclusions: Higher UPF intake was associated with worse CVH, while higher MPF intake was associated with better CVH among WRA in the United States. Our analyses highlight an opportunity for WRA to improve nutrition and their CVH.

Hypertension Prevalence and Control Among U.S. Women of Reproductive Age.

INTRODUCTION: Hypertension is a risk factor for cardiovascular disease, a leading cause of death among women of reproductive age (women aged 18-44 years). This study estimated hypertension prevalence and control among women of reproductive age at the national and state levels using electronic health record data. METHODS: Nonpregnant women of reproductive age were included in this cross-sectional study using 2019 IQVIA Ambulatory Electronic Medical Records - U.S. national data (analyzed in 2023). Suspected hypertension was identified using any of these criteria: ≥1 hypertension diagnosis code, ≥2 blood pressure readings ≥140/90 mmHg on separate days, or ≥1 antihypertensive medication. Among women of reproductive age with hypertension, the latest blood pressure in 2019 was used to identify hypertension control (blood pressure <140/90 mmHg). Estimates were age standardized and stratified by race or Hispanic ethnicity, region, and states with sufficient data. Tukey tests compared estimates by race or Hispanic ethnicity, region, and comorbidities. RESULTS: Among 2,125,084 women of reproductive age (62.1% White, 8.8% Black, and 29.1% other [including Hispanic, Asian, other, or unknown]) with a mean age of 31.7 years, hypertension prevalence was 14.5%. Of those with hypertension, 71.9% had controlled blood pressure. Black women of reproductive age had a higher hypertension prevalence (22.3% vs 14.4%, p<0.05) but lower control (60.6% vs 74.0%, p<0.05) than White women of reproductive age. State-level hypertension prevalence ranged from 13.7% (Massachusetts) to 36% (Alabama), and control ranged from 82.9% (Kansas) to 59.2% (the District of Columbia). CONCLUSIONS: This study provides the first state-level estimates of hypertension control among women of reproductive age. Electronic health record data complements traditional hypertension surveillance data and provides further information for efforts to prevent and manage hypertension among women of reproductive age.

Timing of outpatient postpartum care utilization among women with chronic hypertension and hypertensive disorders of pregnancy.

BACKGROUND: The postpartum period represents an opportunity to assess the cardiovascular health of women who experience chronic hypertension or hypertensive disorders of pregnancy. OBJECTIVE: This study aimed to determine whether women with chronic hypertension or hypertensive disorders of pregnancy access outpatient postpartum care more quickly compared to women with no hypertension. STUDY DESIGN: We used data from the Merative MarketScan Commercial Claims and Encounters Database. We included 275,937 commercially insured women aged 12 to 55 years who had a live birth or stillbirth delivery hospitalization between 2017 and 2018 and continuous insurance enrollment from 3 months before the estimated start of pregnancy to 6 months after delivery discharge. Using the International Classification of Diseases Tenth Revision Clinical Modification codes, we identified hypertensive disorders of pregnancy from inpatient or outpatient claims from 20 weeks gestation through delivery hospitalization and identified chronic hypertension from inpatient or outpatient claims from the beginning of the continuous enrollment period through delivery hospitalization. Distributions of time-to-event survival curves (time-to-first outpatient postpartum visit with a women's health provider, primary care provider, or cardiology provider) were compared between the hypertension types using Kaplan-Meier estimators and log rank tests. We used Cox proportional hazards models to estimate adjusted hazard ratios and 95% confidence intervals. Time points of interest (3, 6, and 12 weeks) were evaluated per clinical postpartum care guidelines. RESULTS: Among commercially insured women, the prevalences of hypertensive disorders of pregnancy, chronic hypertension, and no documented hypertension were 11.7%, 3.4%, and 84.8%, respectively. The proportions of women with a visit within 3 weeks of delivery discharge were 28.5%, 26.4%, and 16.0% for hypertensive disorders of pregnancy, chronic, and no documented hypertension, respectively; by 12 weeks, the proportions increased to 62.4%, 64.5%, and 54.2%, respectively. Kaplan-Meier analyses indicated significant differences in utilization by hypertension type and interaction between hypertension type, and time before and after 6 weeks. In adjusted Cox proportional hazards models, the utilization rate before 6 weeks among women with hypertensive disorders of pregnancy was 1.42 times the rate for women with no documented hypertension (adjusted hazard ratio, 1.42; 95% confidence interval, 1.39-1.45). Women with chronic hypertension also had higher utilization rates compared to women with no documented hypertension before 6 weeks (adjusted hazard ratio, 1.28; 95% confidence interval, 1.24-1.33). Only chronic hypertension was significantly associated with utilization compared to the no documented hypertension group after 6 weeks (adjusted hazard ratio, 1.09; 95% confidence interval, 1.03-1.14). CONCLUSION: In the 6 weeks following delivery discharge, women with hypertensive disorders of pregnancy and chronic hypertension attended outpatient postpartum care visits sooner than women with no documented hypertension. However, after 6 weeks this difference extended only to women with chronic hypertension. Overall, postpartum care utilization remained around 50% to 60% by 12 weeks in all groups. Addressing barriers to postpartum care attendance can ensure timely care for women at high risk for cardiovascular disease.

Less than ideal cardiovascular health among adults is associated with experiencing adverse childhood events: BRFSS 2019.

Ideal cardiovascular health (CVH) is associated with a lower risk of heart disease and stroke while adverse childhood events (ACEs) are related to health behaviors (e.g., smoking, unhealthy diet) and conditions (e.g., hypertension, diabetes) associated with CVH. Data from the 2019 Behavioral Risk Factor Surveillance System was used to explore ACEs and CVH among 86,584 adults ≥18 years from 20 states. CVH was defined as poor (0-2), intermediate (3-5), and ideal (6-7) from summation of survey indicators (normal weight, healthy diet, adequate physical activity, not smoking, no hypertension, no high cholesterol, and no diabetes). ACEs was summed by number (0,1, 2, 3, and ≥4). A generalized logit model estimated associations between poor and intermediate CVH (ideal as referent) and ACEs accounting for age, race/ethnicity, sex, education, and health care coverage. Overall, 16.7% (95% Confidence Interval[CI]:16.3-17.1) had poor, 72.4% (95%CI:71.9-72.9) had intermediate, and 10.9% (95%CI:10.5-11.3) had ideal CVH. Zero ACEs were reported for 37.0% (95%CI:36.4-37.6), 22.5% (95%CI:22.0-23.0) reported 1, 12.7% (95%CI:12.3-13.1) reported 2, 8.5% (95%CI:8.2-8.9) reported 3, and 19.3% (95%CI:18.8-19.8) reported ≥4 ACEs. Those with 1 (Adjusted Odds Ratio [AOR] = 1.27;95%CI = 1.11-1.46), 2 (AOR = 1.63;95%CI:1.36-1.96), 3 (AOR = 2.01;95%CI:1.66-2.44), and ≥ 4 (AOR = 2.47;95%CI:2.11-2.89) ACEs were more likely to report poor (vs. ideal) CVH compared to those with 0 ACEs. Those who reported 2 (AOR = 1.28;95%CI = 1.08-1.51), 3 (AOR = 1.48;95%CI:1.25-1.75), and ≥ 4 (AOR = 1.59;95%CI:1.38-1.83) ACEs were more likely to report intermediate (vs. ideal) CVH compared to those with 0 ACEs. Preventing and mitigating the harms of ACEs and addressing barriers to ideal CVH, particularly social and structural determinants, may improve health.

Clinician Knowledge and Practices Related to a Patient History of Hypertensive Disorders of Pregnancy.

OBJECTIVE: To describe clinician screening practices for prior hypertensive disorders of pregnancy, knowledge of future risks associated with hypertensive disorders of pregnancy, barriers and facilitators to referrals for cardiovascular disease risk evaluation in women with prior hypertensive disorders of pregnancy, and variation by clinician- and practice-level characteristics. METHODS: We used data from Fall DocStyles 2020, a cross-sectional, web-based panel survey of currently practicing U.S. clinicians. Of 2,231 primary care physicians, obstetrician-gynecologists (ob-gyns), nurse practitioners, and physician assistants invited to participate, 67.3% (n=1,502) completed the survey. We calculated the prevalence of screening, knowledge of future risks, and barriers and facilitators to referrals, and assessed differences by clinician type using χ2 tests. We evaluated associations between clinician- and practice-level characteristics and not screening using a multivariable log-binomial model. RESULTS: Overall, 73.6% of clinicians screened patients for a history of hypertensive disorders of pregnancy; ob-gyns reported the highest rate of screening (94.8%). Overall, 24.8% of clinicians correctly identified all cardiovascular risks associated with hypertensive disorders of pregnancy listed in the survey. Lack of patient follow-through (51.5%) and patient refusal (33.6%) were the most frequently cited barriers to referral. More referral options (42.9%), patient education materials (36.2%), and professional guidelines (34.1%) were the most frequently cited resources needed to facilitate referrals. In the multivariable model, primary care physicians and nurse practitioners, as well as physician assistants, were more likely than ob-gyns to report not screening (adjusted prevalence ratio 5.54, 95% CI 3.24-9.50, and adjusted prevalence ratio 7.42, 95% CI 4.27-12.88, respectively). Clinicians seeing fewer than 80 patients per week (adjusted prevalence ratio 1.81, 95% CI 1.43-2.28) were more likely to not screen relative to those seeing 110 or more patients per week. CONCLUSION: Three quarters of clinicians reported screening for a history of hypertensive disorders of pregnancy; however, only one out of four clinicians correctly identified all of the cardiovascular risks associated with hypertensive disorders of pregnancy listed in the survey.

Prevalence, Treatment, and Control of Hypertension Among US Women of Reproductive Age by Race/Hispanic Origin.

BACKGROUND: To explore the prevalence, pharmacologic treatment, and control of hypertension among US nonpregnant women of reproductive age by race/Hispanic origin to identify potential gaps in care. METHODS: We pooled data from the 2011 to March 2020 (prepandemic) National Health and Nutrition Examination Survey cycles. Our analytic sample included 4,590 nonpregnant women aged 20-44 years who had at least 1 examiner-measured blood pressure (BP) value. We estimated prevalences and 95% confidence intervals (CIs) of hypertension, pharmacologic treatment, and control based on the 2003 Joint Committee on High Blood Pressure (JNC 7) and the 2017 American College of Cardiology and the American Heart Association (ACC/AHA) guidelines. We evaluated differences by race/Hispanic origin using Rao-Scott chi-square tests. RESULTS: Applying ACC/AHA guidelines, hypertension prevalence ranged from 14.0% (95% CI: 12.0, 15.9) among Hispanic women to 30.9% (95% CI: 27.8, 34.0) among non-Hispanic Black women. Among women with hypertension, non-Hispanic Black women had the highest eligibility for pharmacological treatment (65.5%, 95% CI: 60.4, 70.5); current use was highest among White women (61.8%, 95% CI: 53.8, 69.9). BP control ranged from 5.2% (95% CI: 1.1, 9.3) among women of another or multiple non-Hispanic races to 18.6% (95% CI: 12.1, 25.0) among Hispanic women. CONCLUSIONS: These findings highlight the importance of monitoring hypertension, pharmacologic treatment, and control by race/Hispanic origin and addressing barriers to equitable hypertension care among women of reproductive age.

Hypertensive Disorders in Pregnancy and Mortality at Delivery Hospitalization - United States, 2017-2019.

Hypertensive disorders in pregnancy (HDPs), defined as prepregnancy (chronic) or pregnancy-associated hypertension, are common pregnancy complications in the United States.* HDPs are strongly associated with severe maternal complications, such as heart attack and stroke (1), and are a leading cause of pregnancy-related death in the United States.† CDC analyzed nationally representative data from the National Inpatient Sample to calculate the annual prevalence of HDP among delivery hospitalizations and by maternal characteristics, and the percentage of in-hospital deaths with an HDP diagnosis code documented. During 2017-2019, the prevalence of HDP among delivery hospitalizations increased from 13.3% to 15.9%. The prevalence of pregnancy-associated hypertension increased from 10.8% in 2017 to 13.0% in 2019, while the prevalence of chronic hypertension increased from 2.0% to 2.3%. Prevalence of HDP was highest among delivery hospitalizations of non-Hispanic Black or African American (Black) women, non-Hispanic American Indian and Alaska Native (AI/AN) women, and women aged ≥35 years, residing in zip codes in the lowest median household income quartile, or delivering in hospitals in the South or the Midwest Census regions. Among deaths that occurred during delivery hospitalization, 31.6% had any HDP documented. Clinical guidance for reducing complications from HDP focuses on prompt identification and preventing progression to severe maternal complications through timely treatment (1). Recommendations for identifying and monitoring pregnant persons with hypertension include measuring blood pressure throughout pregnancy,§ including self-monitoring. Severe complications and mortality from HDP are preventable with equitable implementation of strategies to identify and monitor persons with HDP (1) and quality improvement initiatives to improve prompt treatment and increase awareness of urgent maternal warning signs (2).

Clinical Practice Changes in Monitoring Hypertension Early in the COVID-19 Pandemic.

BACKGROUND: Clinical practices can use telemedicine and other strategies (e.g., self-measured blood pressure [SMBP]) for remote monitoring of hypertension to promote control while decreasing risk of exposure to SARS-CoV-2, the virus that causes COVID-19. METHODS: The DocStyles survey collected data from primary care providers (PCPs), obstetricians-gynecologists (OB/GYNs), and nurse practitioners/physician assistants (NP/PAs) in fall 2020 (n = 1,502). We investigated clinical practice changes for monitoring hypertension that were implemented early in the COVID-19 pandemic and examined differences by clinician and practice characteristics (P < 0.05). RESULTS: Overall, 369 (24.6%) of clinicians reported their clinical practices made no changes in monitoring hypertension early in the pandemic, 884 (58.9%) advised patients to monitor blood pressure at home or a pharmacy, 699 (46.5%) implemented or increased use of telemedicine for blood pressure monitoring visits, and 545 (36.3%) reduced the frequency of office visits for blood pressure monitoring. Compared with NP/PAs, PCPs were more likely to advise SMBP monitoring (adjusted prevalence ratios [aPR] 1.28, 95% confidence intervals [CI] 1.11-1.47), implement or increase use of telemedicine (aPR 1.23, 95% CI 1.04-1.46), and reduce the frequency of office visits (aPR 1.37, 95% CI 1.11-1.70) for blood pressure monitoring, and less likely to report making no practice changes (aPR 0.63, 95% CI 0.51-0.77). CONCLUSIONS: We noted variation in clinical practice changes by clinician type and practice characteristics. Clinical practices may need additional support and resources to fully maximize telemedicine and other strategies for remote monitoring of hypertension during pandemics and other emergencies that can disrupt routine health care.

Blood Pressure Control Among Non-Hispanic Black Adults Is Lower Than Non-Hispanic White Adults Despite Similar Treatment With Antihypertensive Medication: NHANES 2013-2018.

BACKGROUND: Controlled blood pressure can prevent or reduce adverse health outcomes. Social and structural determinants may contribute to the disparity that despite equivalent proportions on antihypertensive medication, non-Hispanic Black (Black) adults have lower blood pressure control and more cardiovascular events than non-Hispanic White (White) adults. METHODS: Data from 2013 to 2018 National Health and Nutrition Examination Survey were pooled to assess control among Black and White adults by antihypertensive medication use and selected characteristics using the 2017 American College of Cardiology/American Heart Association (ACC/AHA) Blood Pressure Guideline definition (systolic blood pressure <130 mm Hg and diastolic blood pressure <80 mm Hg) among 4,739 adults. RESULTS: Among those treated with antihypertensive medication, an estimated 34.9% of Black and 45.0% of White adults had controlled blood pressure. Control was lower for Black and White adults among most subgroups of age, sex, education, insurance status, usual source of care, and poverty-income ratio. Black adults had higher use of diuretics (28.5%-Black adults vs. 23.5%-White adults) and calcium channel blockers (24.2%-Black adults vs. 14.7%-White adults) compared with White adults. Control among Black adults was lower than White adults across all medication classes including diuretics (36.1%-Black adults vs. 47.3%-White adults), calcium channel blockers (30.2%-Black adults vs. 40.1%-White adults), and number of medication classes used. CONCLUSIONS: Suboptimal blood pressure control rates and disparities warrant increased efforts to improve control, which could include addressing social and structural determinants along with emphasizing implementation of the 2017 ACC/AHA Blood Pressure Guideline into clinical practice.

Environmental Classification in Hearing Aids.

There are two parts to this article. The first is a general overview of how hearing aid classification works, including a comparison study of normal-hearing listeners and multiple manufacturers' hearing aids while listening to a sound parkour composed of a multitude of acoustic scenes. Most hearing aids applied nearly identical classification for simple listening environments. But differences began to appear across manufacturers' products when the listening environments became more complex. The second section reviews the results of a study of the acoustic ecology (listening environments) experienced by several cohorts of hearing aid users over a 4-month period. The percentages of time people spent in seven different listening environments were mapped. It was learned that they spent an average of 57% of their time in conversation and that age is not a good predictor of the amount of time spent in most listening environments. This is because, when grouped by age, there was little to no difference in the distribution of time spent in the seven listening environments, whereas there was tremendous variability within each age group.

Sociodemographic and Geographic Variation in Awareness of Stroke Signs and Symptoms Among Adults - United States, 2017.

Stroke is the fifth leading cause of death in the United States (1). In 2017, on average, a stroke-related death occurred every 3 minutes and 35 seconds in the United States, and stroke is a leading cause of long-term disability (1). To prevent mortality or long-term disability, strokes require rapid recognition and early medical intervention (2,3). Common stroke signs and symptoms include sudden numbness or weakness of the face, arm, or leg, especially on one side; sudden confusion or trouble speaking; sudden trouble seeing in one or both eyes; sudden trouble walking, dizziness, or loss of balance; and a sudden severe headache with no known cause. Recommended action at the first sign of a suspected stroke is to quickly request emergency services (i.e., calling 9-1-1) (2). Public education campaigns have emphasized recognizing stroke signs and symptoms and the importance of calling 9-1-1, and stroke knowledge increased 14.7 percentage points from 2009 to 2014 (4). However, disparities in stroke awareness have been reported (4,5). Knowledge of the five signs and symptoms of stroke and the immediate need to call emergency medical services (9-1-1), collectively referred to as "recommended stroke knowledge," was assessed among 26,076 adults aged ≥20 years as part of the 2017 National Health Interview Survey (NHIS). The prevalence of recommended stroke knowledge among U.S. adults was 67.5%. Stroke knowledge differed significantly by race and Hispanic origin (p<0.001). The prevalence of recommended stroke knowledge was highest among non-Hispanic White adults (71.3%), followed by non-Hispanic Black adults (64.0%) and Hispanic adults (57.8%). Stroke knowledge also differed significantly by sex, age, education, and urbanicity. After multivariable adjustment, these differences remained significant. Increasing awareness of the signs and symptoms of stroke continues to be a national priority. Estimates from this report can inform public health strategies for increasing awareness of stroke signs and symptoms.

Prevalence and Risk Factors for Self-Reported Postpartum Depression Symptoms (SRPDS) in Hawai'i, 2012-2015.

Postpartum depression (PPD) affects an estimated 10% to 20% of women in the United States, but little is known about the risk factors for PPD in Hawai'i. This study sought to identify PPD risk factors and examine whether disparities exist in Hawai'i. Aggregated 2012-2015 Hawai'i Pregnancy Risk Assessment Monitoring System (PRAMS) data from 5572 women with a recent live birth were analyzed. Two questions on the PRAMS survey about mood and interest in activities were used to create a brief measure of Self-Reported Postpartum Depression Symptoms (SRPDS). Multivariate generalized logit analysis was conducted to identify risk factors associated with SRPDS or possible SRPDS, adjusting for maternal race and age, intimate partner violence (IPV), prenatal anxiety, prenatal depression, illicit drug use before pregnancy, and stressful life events (SLEs). About 10.0% of women surveyed had SRPDS and 27.7% had possible SRPDS. SRPDS was more common among Native Hawaiians (adjusted odds ratios=1.77; 95% confidence interval: 1.17-2.70), Filipinos (2.16; 1.33-3.50), Japanese (2.88; 1.67-4.98), and other Pacific Islanders (OPI; 3.22; 1.78-5.82), when compared to white. Women aged 20-29 years (0.39; 0.24-0.65) and 30-52 years (0.41; 0.24-0.69) were less likely to have SRPDS than those 19 years and younger. SRPDS was highest among women who experienced IPV (2.65; 1.37-5.13), prenatal anxiety (2.10; 1.28-3.42), prenatal depression (2.78; 1.47-5.25), or used illicit drugs before pregnancy (1.97; 1.21-3.20). There was an upward trend in SRPDS based on the number of SLEs. Possible SRPDS had similar but smaller effects, suggesting the importance of clinical screening and appropriate follow-up for these high-risk groups.

Trends in Selected Chronic Conditions and Related Risk Factors Among Women of Reproductive Age: Behavioral Risk Factor Surveillance System, 2011-2017.

Introduction: Chronic diseases in the United States are the leading drivers of disability, death, and health care costs. In women of reproductive age (WRA), chronic disease and related risk factors can also affect fertility and reproductive health outcomes. This analysis of trends from 2011 to 2017 adds additional indicators and updates an analysis covering 2001-2009. Methods: Data from the 2011-2017 Behavioral Risk Factor Surveillance System were analyzed for 265,544 WRA (18-44 years). To assess trends in 12 chronic conditions and related risk factors, we calculated annual prevalence estimates and adjusted prevalence ratios (APRs) with predicted marginals accounting for age, race, Hispanic ethnicity, education, and health care coverage. Results: From 2011 to 2017, prevalence decreased for current smoking (20.7%-15.9%; p < 0.001), gestational diabetes (3.1%-2.7%; p = 0.003), and high cholesterol (19.0%-16.7%; p < 0.001); prevalence increased for depression (20.4%-24.9%; p < 0.001) and obesity (24.6%-27.6%; p < 0.001). After adjustment, in 2017 WRA were more likely to report asthma (APR = 1.06; 95% confidence interval [CI] = 1.01-1.11), physical inactivity (APR = 1.08; 95% CI = 1.04-1.12), obesity (APR = 1.15; 95% CI = 1.11-1.19), and depression (APR = 1.29; 95% CI = 1.25-1.34) compared with 2011. They were less likely to report high cholesterol (APR = 0.89; 95% CI = 0.85-0.94) in 2015 compared with 2011, and current smoking (APR = 0.86; 95% CI = 0.82-0.89) and gestational diabetes (APR = 0.84; 95% CI = 0.75-0.94) in 2017 compared with 2011. Conclusions: Some chronic conditions and related risk factors improved, whereas others worsened over time. Research clarifying reasons for these trends may support the development of targeted interventions to promote improvements, potentially preventing adverse reproductive outcomes and promoting long-term health.

Maternal Race Trends in Early Infant Feeding Patterns in Hawai'i Using Newborn Metabolic Screening-Birth Certificate Linked Data 2008-2015.

Breastfeeding provides optimal nutrition for infants, including short- and longterm health benefits for baby and mother. Maternity care practices supporting breastfeeding after delivery increase the likelihood of exclusive breastfeeding. This study explores trends in early infant feeding practices by maternal race and other characteristics in Hawai'i. Data from a linked 2008-2015 Hawai'i Newborn Metabolic Screening and Birth Certificate file for 128 399 singleton term infants were analyzed. Early infant feeding occurring 24-48 hours after delivery and before discharge was categorized: Early formula feeding; early mixed feeding; and early exclusive breastfeeding. Differences were assessed over time by maternal race and other socio-demographic characteristics. Further assessment of maternal race included a generalized logit model adjusting for maternal age, marital status, county of residence, type of birth attendant, and birth year. Statewide, early exclusive breastfeeding increased from 58.8% in 2008 to 79.1% in 2015 (relative increase=+35%); early mixed feeding declined from 31.1% to 16.0% (relative decrease=-49%) and early formula feeding declined from 10.1% to 4.9% (relative decrease=-51%). Most maternal race subgroups experienced increases in early exclusive breastfeeding and decreases in mixed and formula. Japanese mothers were 2.15 (95%CI=1.90-2.42) and Korean mothers were 1.73 (95%CI=1.37-2.18) times more likely to practice early exclusive breastfeeding compared with white mothers. Several subgroups were less likely to practice early exclusive breastfeeding compared with white mothers. Substantial increases in early exclusive breastfeeding in Hawai'i occurred across all subgroups. Development of culturally appropriate hospital practices, particularly in those with persistently lower estimates, could help improve early exclusive breastfeeding.

Highly-Effective Contraception Use More Likely Among Native Hawaiian Women than Non-Native Hawaiian Women at Title X Clinics in Hawai'i.

Differences in contraceptive method use have been noted among women of different races, but studies describing contraceptive method use among Native Hawaiian women have not been published. To examine method choice in this group, the authors conducted a database review of the Hawai'i State Department of Health Title X program. Reviewed were client visit records (CVRs) that health care providers completed for women who were ages 15-44 years, avoiding pregnancy, not currently pregnant, and using a contraceptive method (N=54 513). Because a patient could have had several visits during the study period, the contraceptive method chosen at the last visit was selected for analysis. Statistical analyses included descriptive statistics, bivariate analyses, and logistic regression. The proportion of Native Hawaiian women who selected a highly-effective method of contraception (HEC), defined as an intrauterine device, implant, or permanent contraception, was higher than the proportion of non-Native Hawaiian women who selected an HEC. Overall, 15.4% of Native Hawaiian women during the study period chose HEC, compared to 8.8% of non-Native Hawaiian women. In a logistic regression analysis, Native Hawaiian women ages 15-29 were 1.46 times more likely to use HEC (95% CI: 1.35-1.58) than non-Native Hawaiian women ages 15-29, and Native Hawaiian women ages 30-44 were 1.69 times more likely to use HEC (95% CI: 1.53-1.87) than non-Native Hawaiian women in the same age group. Because Native Hawaiian women are reported to have higher rates of unintended pregnancy in the state compared to other racial groups, additional research exploring contraceptive non-use and pregnancy intention are needed.

Estimation of water quality profiles in deep lakes based on easily measurable constituents at the water surface using artificial neural networks coupled with stationary wavelet transform.

This study proposes a novel framework to accurately estimate water quality profiles in deep lakes based on parameters measured at the water surface, considering Boulder Basin of Lake Mead as a case study. Hourly-measured meteorological data were used to compute heat exchange between lake and atmosphere. Heat fluxes combined with every 6-hour measured water temperature, conductivity, and dissolved oxygen (DO) profiles, from the water surface to a depth of 100 m over a 48-month period, were used to train seven different artificial neural network-based methods for estimating water quality profiles. Effects of different factors influencing lake water quality, including lake-atmosphere interactions, wind-induced mixing, thermocline depth, winter turnover, oxygen depletion and other factors were investigated in different methods. A method employing stationary wavelet transform with a depth-progressive estimation of temperature, conductivity, and DO generated the smallest average relative errors of 0.52%, 0.22%, and 0.62%, respectively in the water column over a 48-month period. Abrupt changes in temperature, conductivity, and DO profiles due to thermal stratification, winter turnover, and oxygen hypoxia increased estimation errors. The largest errors occurred near the interface between the epilimnion and metalimnion, where vertical mixing intensity significantly decreased.
