RESUMO

Social determinants of health (SDOH) are a broad array of social and contextual conditions where persons are born, live, learn, work, play, worship, and age that influence their physical and mental wellbeing and quality of life. Using 2022 Behavioral Risk Factor Surveillance System data, this study assessed measures of adverse SDOH and health-related social needs (HRSN) among U.S. adult populations. Measures included life satisfaction, social and emotional support, social isolation or loneliness, employment stability, food stability/security, housing stability/security, utility stability/security, transportation access, mental well-being, and health care access. Prevalence ratios were adjusted for age, sex, education, marital status, income, and self-rated health. Social isolation or loneliness (31.9%) and lack of social and emotional support (24.8%) were the most commonly reported measures, both of which were more prevalent among non-Hispanic (NH) American Indian or Alaska Native, NH Black or African American, NH Native Hawaiian or other Pacific Islander, NH multiracial, and Hispanic or Latino adults than among NH White adults. The majority of prevalence estimates for other adverse SDOH and HRSN were also higher across all other racial and ethnic groups (except for NH Asian) compared with NH White adults. SDOH and HRSN data can be used to monitor needed social and health resources in the U.S. population and help evaluate population-scale interventions.

RESUMO

Depression is a major contributor to mortality, morbidity, disability, and economic costs in the United States (1). Examining the geographic distribution of depression at the state and county levels can help guide state- and local-level efforts to prevent, treat, and manage depression. CDC analyzed 2020 Behavioral Risk Factor Surveillance System (BRFSS) data to estimate the national, state-level, and county-level prevalence of U.S. adults aged ≥18 years self-reporting a lifetime diagnosis of depression (referred to as depression). During 2020, the age-standardized prevalence of depression among adults was 18.5%. Among states, the age-standardized prevalence of depression ranged from 12.7% to 27.5% (median = 19.9%); most of the states with the highest prevalence were in the Appalachian* and southern Mississippi Valley† regions. Among 3,143 counties, the model-based age-standardized prevalence of depression ranged from 10.7% to 31.9% (median = 21.8%); most of the counties with the highest prevalence were in the Appalachian region, the southern Mississippi Valley region, and Missouri, Oklahoma, and Washington. These data can help decision-makers prioritize health planning and interventions in areas with the largest gaps or inequities, which could include implementation of evidence-based interventions and practices such as those recommended by The Guide to Community Preventive Services Task Force (CPSTF) and the Substance Abuse and Mental Health Services Administration (SAMHSA).

RESUMO

OBJECTIVES: To examine the association between chronic obstructive pulmonary disease status and indicators of economic instability and stress to better understand the magnitude of these issues in persons with chronic obstructive pulmonary disease. METHODS: Analyzed 2017 Behavioral Risk Factor Surveillance System data from 16 states that administered the 'Social Determinants of Health' module, which included economic instability and stress measures (N = 101,461). Associations between self-reported doctor-diagnosed chronic obstructive pulmonary disease status and each measure were examined using multinomial logistic models. RESULTS: Adults with chronic obstructive pulmonary disease were more likely (p < 0.001) than adults without to report not having enough money at month end (21.0% vs. 7.9%) or just enough money (44.9% vs. 37.2%); being unable to pay mortgage, rent, or utility bills (19.2% vs. 8.8%); and that often or sometimes food did not last or could not afford to eat balanced meals (37.9% vs. 20.6%), as well as stress all or most of the time (27.3% vs. 11.6%). Associations were attenuated although remained significant after adjustments for sociodemographic and health characteristics. DISCUSSION: Financial, housing, and food insecurity and frequent stress were more prevalent in adults with chronic obstructive pulmonary disease than without. Findings highlight the importance of including strategies to address challenges related to economic instability and stress in chronic obstructive pulmonary disease management programs.

RESUMO

Chronic conditions are common, costly, and major causes of death and disability.* Addressing chronic conditions and their determinants in young adulthood can help slow disease progression and improve well-being across the life course (1); however, recent prevalence estimates examining chronic conditions in young adults overall and by subgroup have not been reported. CDC analyzed data from the Behavioral Risk Factor Surveillance System (BRFSS) to measure prevalence of 11 chronic conditions among adults aged 18-34 years overall and by selected characteristics, and to measure prevalence of health-related risk behaviors by chronic condition status. In 2019, more than one half (53.8%) of adults aged 18-34 years reported having at least one chronic condition, and nearly one quarter (22.3%) reported having more than one chronic condition. The most prevalent conditions were obesity (25.5%), depression (21.3%), and high blood pressure (10.7%). Differences in the prevalence of having a chronic condition were most noticeable between young adults with a disability (75.8%) and without a disability (48.3%) and those who were unemployed (62.3%) and students (45.8%). Adults aged 18-34 years with a chronic condition were more likely than those without one to report binge drinking, smoking, or physical inactivity. Coordinated efforts by public and private sectors might help raise awareness of chronic conditions among young adults and help improve the availability of evidence-based interventions, policies, and programs that are effective in preventing, treating, and managing chronic conditions among young adults (1).

RESUMO

Alzheimer disease,* the most common cause of dementia, affects an estimated 6.5 million persons aged ≥65 years in the United States (1). A growing body of evidence has identified potential modifiable risk factors for Alzheimer disease and related dementias (ADRD) (1-3). In 2021, the National Plan to Address Alzheimer's Disease (National Plan) introduced a new goal to "accelerate action to promote healthy aging and reduce risk factors for Alzheimer's disease and related dementias" to help delay onset or slow the progression of ADRD (3). To assess the status of eight potential modifiable risk factors (i.e., high blood pressure, not meeting the aerobic physical activity guideline, obesity, diabetes, depression, current cigarette smoking, hearing loss, and binge drinking), investigators analyzed data from the cognitive decline module that was administered to adults aged ≥45 years in 31 states and the District of Columbia (DC)† in the 2019 Behavioral Risk Factor Surveillance System (BRFSS) survey. Among the risk factors, prevalence was highest for high blood pressure (49.9%) and lowest for binge drinking (10.3%) and varied by selected demographic characteristics. Adults with subjective cognitive decline (SCD),§ an early indicator of possible future ADRD (4), were more likely to report four or more risk factors than were those without SCD (34.3% versus 13.1%). Prevalence of SCD was 11.3% overall and increased from 3.9% among adults with no risk factors to 25.0% among those with four or more risk factors. Implementing evidence-based strategies to address modifiable risk factors can help achieve the National Plan's new goal to reduce risk for ADRD while promoting health aging.¶,*.

RESUMO

Emergency departments (EDs) in the United States remain a frontline resource for pediatric health care emergencies during the COVID-19 pandemic; however, patterns of health-seeking behavior have changed during the pandemic (1,2). CDC examined changes in U.S. ED visit trends to assess the continued impact of the pandemic on visits among children and adolescents aged 0-17 years (pediatric ED visits). Compared with 2019, pediatric ED visits declined by 51% during 2020, 22% during 2021, and 23% during January 2022. Although visits for non-COVID-19 respiratory illnesses mostly declined, the proportion of visits for some respiratory conditions increased during January 2022 compared with 2019. Weekly number and proportion of ED visits increased for certain types of injuries (e.g., drug poisonings, self-harm, and firearm injuries) and some chronic diseases, with variation by pandemic year and age group. Visits related to behavioral concerns increased across pandemic years, particularly among older children and adolescents. Health care providers and families should remain vigilant for potential indirect impacts of the COVID-19 pandemic, including health conditions resulting from delayed care, and increasing emotional distress and behavioral health concerns among children and adolescents.

RESUMO

In 2021, a national emergency* for children's mental health was declared by several pediatric health organizations, and the U.S. Surgeon General released an advisory† on mental health among youths. These actions resulted from ongoing concerns about children's mental health in the United States, which was exacerbated by the COVID-19 pandemic (1,2). During March-October 2020, among all emergency department (ED) visits, the proportion of mental health-related visits increased by 24% among U.S. children aged 5-11 years and 31% among adolescents aged 12-17 years, compared with 2019 (2). CDC examined changes in U.S. pediatric ED visits for overall mental health conditions (MHCs) and ED visits associated with specific MHCs (depression; anxiety; disruptive behavioral and impulse-control disorders; attention-deficit/hyperactivity disorder; trauma and stressor-related disorders; bipolar disorders; eating disorders; tic disorders; and obsessive-compulsive disorders [OCD]) during 2019 through January 2022 among children and adolescents aged 0-17 years, overall and by sex and age. After declines in weekly visits associated with MHCs among those aged 0-17 years during 2020, weekly numbers of ED visits for MHCs overall and for specific MHCs varied by age and sex during 2021 and January 2022, when compared with corresponding weeks in 2019. Among adolescent females aged 12-17 years, weekly visits increased for two of nine MHCs during 2020 (eating disorders and tic disorders), for four of nine MHCs during 2021 (depression, eating disorders, tic disorders, and OCD), and for five of nine MHCs during January 2022 (anxiety, trauma and stressor-related disorders, eating disorders, tic disorders, and OCD), and overall MHC visits during January 2022, compared with 2019. Early identification and expanded evidence-based prevention and intervention strategies are critical to improving children's and adolescents' mental health (1-3), especially among adolescent females, who might have increased need.

RESUMO

BACKGROUND: Health plans and risk-bearing provider organizations seek information sources to inform proactive interventions for patients at risk of adverse health events. Interventions should take into account the strong relationship between social context and health. This retrospective cohort study of a Medicare Advantage population examined whether a change in self-reported health-related quality of life (HRQOL) signals a subsequent change in healthcare needs. METHODS: A retrospective longitudinal analysis of administrative claims data was conducted for participants in a Medicare Advantage plan with prescription drug coverage (MAPD) who responded to 2 administrations of the Centers for Disease Control and Prevention 4-item Healthy Days survey within 6-18 months during 2015-2018. Changes in HRQOL, as measured by the Healthy Days instrument, were compared with changes in utilization and costs, which were considered to be a reflection of change in healthcare needs. RESULTS: A total of 48,841 individuals met inclusion criteria. Declining HRQOL was followed by increases in utilization and costs. An adjusted analysis showed that every additional unhealthy day reported one year after baseline was accompanied by an $8 increase in monthly healthcare costs in the subsequent six months for the average patient. CONCLUSIONS: Declining HRQOL signaled subsequent increases in healthcare needs and utilization. IMPLICATIONS: Findings suggest that HRQOL assessments in general, and the Healthy Days instrument in particular, could serve as a leading indicator of the need for interventions designed to mitigate poor health outcomes and rising healthcare costs.

RESUMO

OBJECTIVE: To assess the prevalence of migraine or severe headache among US adults by inflammatory bowel disease (IBD) status. BACKGROUND: Emerging evidence in clinical settings suggests a higher prevalence of migraine among patients with IBD than those without IBD. METHODS: Data from 60,436 US adults aged ≥18 years participating in the 2015 and 2016 National Health Interview Survey (NHIS) were analyzed. The relationship between IBD status and migraine or severe headache was assessed overall and stratified by levels of selected characteristics including sex, age, race/ethnicity, education, poverty status, marital status, smoking status, obesity status, serious psychological distress, and major chronic condition status. RESULTS: Overall, the age-adjusted prevalence of migraine or severe headache was 15.4% (n = 9062) and of IBD was 1.2% (n = 862). A higher age-adjusted migraine or severe headache prevalence was reported among participants with IBD than those without IBD (28.1% vs. 15.2%, p < 0.0001). The association of migraine or severe headache with IBD remained significant overall [adjusted prevalence ratio (95% CI) = 1.59 (1.35-1.86)] and within the levels of most other selected characteristics after controlling for all other covariates. CONCLUSIONS: Our results confirmed a higher prevalence of migraine or severe headache among US adults with IBD than those without. Healthcare providers might assess migraine or severe headache among patients with IBD to improve management and quality of life.

RESUMO

China's portfolio of air-pollution control policy instruments has gradually broadened since the 1970s from regulatory instruments to include numerous market-based and voluntary policy instruments. We demonstrate this broadened portfolio of policy instruments for air-pollution control with a computer-assisted content analysis of 148 central-level policy documents from 1973 to 2016. We identify 20 types of policy instruments in these documents, and analyze such things as their historical evolution, main subjects, frequency of use, and whether they were issued by a single agency or jointly with other agencies. Prior research has found several factors complicating the diversification of policy instruments in China, including the late start of coordinated governance of air pollution, overreliance on regulatory instruments, insufficient use of market-based and voluntary instruments, the high cost of collecting shared information on a web-based platform, and the choice of policy instruments resulting from the "campaign-style" of governance. Given such challenges, we expected the policy documents to show little diversification of policy instruments and little coordination among agencies. The content analysis results show, however, a gradual shift from a centralized, regulatory model to an increasingly coordinated model using a diverse portfolio of policy instruments.

RESUMO

Objectives. To demonstrate a flexible and practical method to obtain near real-time estimates of the number of at-risk community-dwelling adults with a chronic condition in a defined area potentially affected by a public health emergency.Methods. We used small area estimation with survey responses from the 2016 Behavioral Risk Factor Surveillance System together with a geographic information system to predict the number of adults with chronic obstructive pulmonary disease who lived in the forecasted path of Hurricane Florence in North and South Carolina in 2018.Results. We estimated that a range of 32 002 to 676 536 adults with chronic obstructive pulmonary disease resided between 50 and 200 miles of 3 consecutive daily forecasted landfalls. The number of affected counties ranged from 8 to 10 (at 50 miles) to as many as 119 to 127 (at 200 miles).Conclusions. Community preparedness is critical to anticipating, responding to, and ameliorating these health threats. We demonstrated the feasibility of quickly producing detailed estimates of the number of residents with chronic conditions who may face life-threatening situations because of a natural disaster. These methods are applicable to a range of planning and response scenarios.

RESUMO

INTRODUCTION: Continuous quality improvement is a central tenet of the Public Health Accreditation Board's (PHAB) national voluntary public health accreditation program. Similarly, the Centers for Disease Control and Prevention launched the National Public Health Improvement Initiative (NPHII) in 2010 with the goal of advancing accreditation readiness, performance management, and quality improvement (QI). OBJECTIVE: Evaluate the extent to which NPHII awardees have achieved program goals. DESIGN: NPHII awardees responded to an annual assessment and program monitoring data requests. Analysis included simple descriptive statistics. SETTING: Seventy-four state, tribal, local, and territorial public health agencies receiving NPHII funds. PARTICIPANTS: NPHII performance improvement managers or principal investigators. MAIN OUTCOME MEASURE(S): Development of accreditation prerequisites, completion of an organizational self-assessment against the PHAB Standards and Measures, Version 1.0, establishment of a performance management system, and implementation of QI initiatives to increase efficiency and effectiveness. RESULTS: Of the 73 responding NPHII awardees, 42.5% had a current health assessment, 26% had a current health improvement plan, and 48% had a current strategic plan in place at the end of the second program year. Approximately 26% of awardees had completed an organizational PHAB self-assessment, 72% had established at least 1 of the 4 components of a performance management system, and 90% had conducted QI activities focused on increasing efficiencies and/or effectiveness. CONCLUSIONS: NPHII appears to be supporting awardees' initial achievement of program outcomes. As NPHII enters its third year, there will be additional opportunities to advance the work of NPHII, compile and disseminate results, and inform a vision of high-quality public health necessary to improve the health of the population.

RESUMO

Evaluating emergency risk communications is fraught with challenges since communication can be approached from both a systemic and programmatic level. Therefore, one must consider stakeholders' perspectives, effectiveness issues, standards of evidence and utility, and channels of influence (e.g., mass media and law enforcement). Evaluation issues related to timing, evaluation questions, methods, measures, and accountability are raised in this dialogue with emergency risk communication specialists. Besides the usual evaluation competencies, evaluators in this area need to understand and work collaboratively with stakeholders and be attuned to the dynamic contextual nature of emergency risk communications. Sample resources and measures are provided here to aid in this emerging and exciting field of evaluation.

RESUMO

The Centers for Disease Control and Prevention (CDC) Division of HIV/AIDS Prevention (DHAP) has responded to the need for accurate and timely data to monitor and evaluate federally funded HIV prevention programs by designing and implementing the Program Evaluation and Monitoring System (PEMS). PEMS is a national data reporting system that includes a standardized set of HIV prevention data variables, Web-based software for data entry and management, data collection and evaluation guidance and training, and software implementation support services. This article discusses the purposes of evaluation and the need for and development of PEMS and also describes how PEMS strengthens the monitoring and evaluation of HIV prevention services nationally and program planning, management, and monitoring locally. PEMS data may be used by prevention stakeholders at all levels to examine program fidelity, adaptation and tailoring, and key program health service utilization and behavioral outcomes. PEMS provides a strong foundation to bring a program closer to its intended goals and to serve the needs of the clients and the community, provides a means for agencies to fulfill their reporting mandates and funding obligations, and enables the CDC to monitor HIV prevention efforts in a consistent, efficient, and effective manner across the United States.

RESUMO

The impact of starvation on the digestive enzyme (protease, trypsin, lipase and amylase) activities of Stage I and IV Jasus edwardsii phyllosoma larvae was used to identify the nutrients metabolised or conserved during food deprivation, highlighting the most critical energy reserves. Protease activities increased significantly in both Stages I and IV phyllosoma, suggesting that protein catabolism provided energy during food deprivation. Lipase activity decreased significantly in starved Stages I and IV larvae indicating that lipid may be spared for fuelling later developmental moults. The use of protein, while sparing lipid, may provide immediate energy but not at the expense of long-term lipid energy stores which are known to be important during their lengthy larval phase. The preferential use of protein during short-term periods of starvation suggests that particular attention must be given to providing sufficient protein in artificial diets at all times. Amylase activity in starved Stage I larvae was lower than in fed animals, suggesting that the starved animals are not gaining sufficient carbohydrate. However, amylase activity was similar in fed and starved Stage IV larvae, possibly due to the catabolism of accumulated glycogen stores that were not sufficiently developed in Stage I animals.
