Risk of Chronic Obstructive Pulmonary Disease and Receipt of a Breathing Test in 26 States and the District of Columbia, 2017-2018.

We estimated the prevalence of respiratory symptoms, chronic obstructive pulmonary disease (COPD) risk level, and receipt of a breathing test among adults without reported COPD in 26 states and the District of Columbia by using 2017-2018 Behavioral Risk Factor Surveillance System data. Among adults without reported COPD, the 3 respiratory symptoms indicating COPD (chronic cough, phlegm or mucus production, shortness of breath) were common (each >10%). About 15.0% were at higher COPD risk (based on the number of symptoms, age, and smoking status); 41.4% of adults at higher risk reported receipt of a breathing test. Patient-provider recognition and communication of risk symptoms, appropriate screening, and follow-up are important for early diagnosis and treatment.

Sleep Duration, Mental Health, and Increased Difficulty Doing Schoolwork Among High School Students During the COVID-19 Pandemic.

We estimated the prevalence of short sleep duration (<8 h/average school night) among high school students (grades 9-12) during the COVID-19 pandemic by using data from the Adolescent Behaviors and Experiences Survey (January-June 2021; N = 7,705). An adjusted logistic regression model predicted prevalence ratios for more difficulty doing schoolwork during the pandemic compared with before the pandemic. Most (76.5%) students experienced short sleep duration, and two-thirds perceived more difficulty doing schoolwork. Students who slept less than 7 hours per school night or experienced poor mental health were more likely to report increased difficulty doing schoolwork. Addressing students' sleep duration could complement efforts to bolster their mental health and learning.

Short Sleep Duration: Children's Mental, Behavioral, and Developmental Disorders and Demographic, Neighborhood, and Family Context in a Nationally Representative Sample, 2016-2019.

INTRODUCTION: Many children and adolescents experience insufficient sleep, which poses risks for their short- and long-term health and development. This study examined the concurrent associations of contextual factors, including child, demographic, neighborhood, and family factors, with short sleep duration. METHODS: We combined data on children aged 3 to 17 years from the 2016-2019 National Survey of Children's Health (N = 112,925) to examine the association of parent-reported child short sleep duration (ages 3-5 y, <10 h; 6-12 y, <9 h; 13-17 y, <8 h) with mental, behavioral, and developmental disorders (MBDDs); selected physical health conditions; and demographic, neighborhood, and family factors. RESULTS: Overall, 34.7% of children experienced short sleep duration. The prevalence was highest among children aged 6 to 12 years (37.5%); children from racial and ethnic minority groups, especially non-Hispanic Black children (50.0%); children from low-income households (44.9%); children with an MBDD (39.6%); children experiencing negative neighborhood factors (poor conditions and lack of safety, support, and amenities, 36.5%); and family factors such as inconsistent bedtime (57.3%), poor parental mental (47.5%) and physical health (46.0%), and adverse childhood experiences (44.1%). The associations between sleep and demographic, neighborhood, and family factors, and MBDD remained significant after controlling for all other factors. CONCLUSION: This study identified several individual, family, and community factors that may contribute to children's short sleep duration and can be targeted to improve healthy development, particularly among children with an MBDD, from households with low socioeconomic status, or from racial and ethnic minority groups who are at increased risk for short sleep duration.

Prevalence and Geographic Patterns of Self-Reported Short Sleep Duration Among US Adults, 2020.

We estimated the prevalence of short sleep duration (<7 hours per day) among US adults aged 18 years or older by using 2020 Behavioral Risk Factor Surveillance System data. Nationally, 33.2% of adults reported short sleep duration. We identified disparities across sociodemographic characteristics, including age, sex, race and ethnicity, marital status, education, income, and urbanicity. Counties with the highest model-based estimates of short sleep duration clustered in the Southeast and along the Appalachian Mountains. These findings identified subgroups and geographic areas in which tailored strategies for promotion of optimal sleep duration (≥7 hours per night) are most needed.

Geographic Differences in Sex-Specific Chronic Obstructive Pulmonary Disease Mortality Rate Trends Among Adults Aged ≥25 Years - United States, 1999-2019.

Chronic obstructive pulmonary disease (COPD) accounts for the majority of deaths from chronic lower respiratory diseases, the fourth leading cause of death in the United States in 2019.* COPD mortality rates are decreasing overall. Although rates in men remain higher than those in women, declines have occurred among men but not women (1). To examine the geographic variation in sex-specific trends in age-adjusted COPD mortality rates among adults aged ≥25 years, CDC analyzed 1999-2019 death certificate data, by urban-rural status,† U.S. Census Bureau region,§ and state. Among women, no significant change in overall COPD mortality occurred during this period; however, rates increased significantly in small metropolitan (average annual percent change [AAPC] = 0.6%), micropolitan (1.2%), and noncore (1.9%) areas and in the Midwest (0.6%). Rates decreased significantly in large central (-0.9%) and fringe metropolitan (-0.4%) areas (and in the Northeast (-0.5%) and West (-1.2%). Among men, rates decreased significantly overall (-1.3%), in all urban-rural areas (range = -1.9% [large central metropolitan] to -0.4% [noncore]) and in all regions (range = -2.0% [West] to -0.9% [Midwest]). Strategies to improve the prevention, treatment, and management of COPD are needed, especially to address geographic differences and improve the trend in women, to reduce COPD deaths.

Short Sleep Duration Among Infants, Children, and Adolescents Aged 4 Months-17 Years - United States, 2016-2018.

Infants, children, and adolescents who do not get sufficient sleep are at increased risk for injuries, obesity, type 2 diabetes, poor mental health, attention and behavior problems, and poor cognitive development (1). The American Academy of Sleep Medicine (AASM) provides age-specific sleep duration recommendations to promote optimal health (1). CDC analyzed data from the 2016-2018 National Survey of Children's Health (NSCH) to assess the prevalence of short sleep duration among persons in the United States aged 4 months-17 years. Overall, on the basis of parent report, 34.9% of persons aged 4 months-17 years slept less than recommended for their age. The prevalence of short sleep duration was higher in southeastern states and among racial and ethnic minority groups, persons with low socioeconomic status, and those with special health care needs. The prevalence of short sleep duration ranged from 31.2% among adolescents aged 13-17 years to 40.3% among infants aged 4-11 months. Persons aged 4 months-17 years with a regular bedtime were more likely to get enough sleep. Public health practitioners, educators, and clinicians might advise parents on the importance of meeting recommended sleep duration and implementing a consistent bedtime for healthy development.

The association between inflammatory bowel disease and migraine or severe headache among US adults: Findings from the National Health Interview Survey, 2015-2016.

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.

Sleep duration and quality among U.S. adults with epilepsy: National Health Interview Survey 2013, 2015, and 2017.

BACKGROUND: Epilepsy is associated with a high prevalence of sleep disturbance. However, population-based studies on the burden of sleep disturbance in people with epilepsy are limited. This study assessed sleep duration and sleep quality by epilepsy status in the general U.S. adult population aged ≥ 18 years. METHODS: We pooled data of cross-sectional National Health Interview Surveys in 2013, 2015, and 2017 to compare the prevalence of sleep duration and quality among those without epilepsy (N = 93,126) with those with any epilepsy (a history of physician-diagnosed epilepsy) (N = 1774), those with active epilepsy (those with a history of physician-diagnosed epilepsy who were currently taking medication to control it, had one or more seizures in the past year, or both) (N = 1101), and those with inactive epilepsy (those with a history of physician-diagnosed epilepsy who were neither taking medication for epilepsy nor had had a seizure in the past year) (N = 673). We also compared these measures between those with active and those with inactive epilepsy. The prevalences were adjusted for sociodemographics, behaviors, and health covariates, with multivariable logistic regression. We used Z-tests to compare prevalences of sleep duration and quality at the statistical significance level of 0.05. RESULTS: Adults with any epilepsy reported significantly higher adjusted prevalences of short sleep duration (<7 h) (36.0% vs. 31.8%) and long sleep duration (>9 h per day) (6.7% vs. 3.7%) but a lower prevalence of healthy sleep duration (7-9 h per day) (57.4% vs.64.6%) than those without epilepsy. In the past week, adults with any epilepsy reported significantly higher adjusted prevalences than adults without epilepsy of having trouble falling asleep (25.0% vs. 20.3%), staying asleep (34.4% vs. 26.3%), nonrestorative sleep (adults did not wake up feeling well rested) (≥3days) (50.3% vs. 44.3%), and taking medication to help themselves fall asleep or stay asleep (≥1 times) (20.9% vs. 13.5%). However, adults with active epilepsy did not differ from adults with inactive epilepsy with respect to these sleep duration and quality measures. CONCLUSIONS: Adults with epilepsy reported more short or long sleep duration and worse sleep quality than those without epilepsy. Neither seizure occurrence nor antiepileptic drug use accounted for these differences in sleep duration and quality. Careful screening for sleep complaints as well as identifying and intervening on the modifiable risk factors associated with sleep disturbances among people with epilepsy could improve epilepsy outcomes and quality of life.

Trends and Outcomes of Hip Fracture Hospitalization Among Medicare Beneficiaries with Inflammatory Bowel Disease, 2000-2017.

BACKGROUND: Patients with inflammatory bowel disease (IBD) have a higher risk of hip fracture, but lower likelihood of having arthroplasties than non-IBD patients in Nationwide Inpatient Sample. Little is known about hip fracture-associated hospitalization outcomes. AIMS: We assessed the trends in hip fracture hospitalization rates from 2000 to 2017 and estimated 30-day readmission, 30-day mortality, and length of stay in 2016 and 2017. METHODS: We estimated trends of age-adjusted hospitalization rates using a piecewise linear regression. Medicare beneficiaries aged ≥ 66 years with Crohn's disease (CD, n = 2014) or ulcerative colitis (UC, n = 2971) hospitalized for hip fracture were identified. We performed propensity score matching to create 1:3 matched samples on age, race/ethnicity, sex, and chronic conditions and compared hospitalization outcomes between matched samples. RESULTS: In 2017, the age-adjusted hospitalization rates (per 100) were 1.15 [95% CI = (1.07-1.24)] for CD, 0.86 [95% CI = (0.82-0.89)] for UC, and 0.59 [95% CI = (0.59-0.59)] for no IBD. The hospitalization rates for CD and UC decreased from 2000 to 2012 and then increased from 2012 to 2017. Compared to matched cohorts, CD patients had longer hospital stays (5.55 days vs. 5.30 days, p = 0.01); UC patients were more likely to have 30-day readmissions (17.27% vs. 13.71%, p < 0.001), longer hospital stays (5.59 days vs. 5.40 days, p = 0.02), and less likely to have 30-day mortality (3.77% vs. 5.15%, p = 0.003). CONCLUSIONS: Prevention of hip fracture is important for older adults with IBD, especially CD. Strategies that improve quality of inpatient care for IBD patients hospitalized for hip fracture should be considered.

Sleep Disorder Symptoms Among Adults in 8 States and the District of Columbia, 2017.

Sleep disorder symptoms (trouble falling asleep or staying asleep, unintentionally falling asleep, snoring loudly, and episodes of having stopped breathing) among US adults (N = 59,108) from 8 states and the District of Columbia were analyzed by using data from the 2017 Behavioral Risk Factor Surveillance System. We conducted a multivariable logistic regression to assess the association between the 4 symptoms and sociodemographic characteristics, risk behaviors, and chronic conditions. The 4 symptoms were prevalent and more likely to be reported among adults with any chronic condition(s) than their counterparts without symptoms and among those who slept fewer than 7 hours compared with those who slept 7 to 9 hours.

Higher Prevalence of Health-Risk Factors Among US Adults With Unmet Health Care Needs Due to Cost, 2016.

CONTEXT: Adults with unmet health care needs (UHCN) due to cost have fewer opportunities to receive behavioral counseling in clinical settings, which may be associated with a higher likelihood of having health-risk behaviors. OBJECTIVE: This study assessed associations between UHCN and health-risk factors. DESIGN/SETTING: We used 2016 Behavioral Risk Factor Surveillance System data to calculate age-adjusted weighted prevalence of 5 health-risk factors by UHCN and insurance status and to assess the association of UHCN with these factors using multivariable logistic regression. PARTICIPANTS: US adults aged 18 to 64 years who participated in the survey (N = 301 035). MAIN OUTCOME MEASURES: Five health-risk factors: obesity, current cigarette smoking, excessive alcohol use, sleeping less than 7 hours per 24-hour period, and no leisure-time physical activity within the past month. RESULTS: In 2016, among adults aged 18 to 64 years, 11.2% of those with insurance and 40.1% of those without insurance (both age-adjusted) had UHCN. In both study populations, compared with adults with no UHCN, adults reporting UHCN were more likely to be a current cigarette smoker, report excessive alcohol use, and sleep less than 7 hours per 24-hour period. The prevalence of 3 or more health-risk factors was higher among adults with UHCN than among adults without UHCN (adults with insurance: adjusted prevalence ratio = 1.40; 95% confidence interval = 1.33-1.48; adults without insurance: adjusted prevalence ratio = 1.39; 95% confidence interval = 1.27-1.53). CONCLUSIONS: Unmet health care needs was associated with more health-risk factors regardless of insurance status. Addressing cost barriers to behavioral counseling may be one approach to consider when seeking to reduce health-risk behaviors among high-risk populations.

Epilepsy and chronic obstructive pulmonary disease among U.S. adults: National Health Interview Survey 2013, 2015, and 2017.

BACKGROUND: Among U.S. adults, over 4 million report a history of epilepsy, and more than 15 million report a history of chronic obstructive pulmonary disease (COPD); Chronic obstructive pulmonary disease, which includes chronic bronchitis and emphysema, is a common somatic comorbidity of epilepsy. This study assessed the relationship between self-reported physician-diagnosed epilepsy and COPD in a large representative sample of the U.S. adult population and explored possible mechanisms. METHODS: Cross-sectional National Health Interview Surveys for 2013, 2015, and 2017 were aggregated to compare the prevalence of COPD between U.S. respondents aged ≥18 years with a history of physician-diagnosed epilepsy (n = 1783) and without epilepsy (n = 93,126). We calculated prevalence of COPD by age-standardized adjustment and prevalence ratios of COPD overall adjusted for sociodemographic and risk factors, by using multivariable logistic regression analyses. A Z-test was conducted to compare the prevalence between people with and without epilepsy at the statistical significance level of 0.05. Prevalence ratios whose 95% confidence intervals did not overlap 1.00 were considered statistically significant. RESULTS: The overall age-standardized prevalence was 5.7% for COPD and 1.8% for epilepsy. Age-standardized prevalence of COPD among respondents with epilepsy (15.4%) exceeded that among those without epilepsy (5.5%). The association remained significantly different among all sociodemographic and risk factor subgroups (p < .05). In the adjusted analyses, epilepsy was also significantly associated with COPD, overall (adjusted prevalence ratio = 1.8, 95% confidence interval = 1.6-2.1) and in nearly all subgroups defined by selected characteristics. CONCLUSIONS: Epilepsy is associated with a higher prevalence of COPD in U.S. adults. Public health interventions targeting modifiable behavioral and socioeconomic risk factors among people with epilepsy may help prevent COPD and related premature death.

Estimating health service utilization potential using the supply-concentric demand-accumulation spatial availability index: a pulmonary rehabilitation case study.

The potential for a population at a given location to utilize a health service can be estimated using a newly developed measure called the supply-concentric demand accumulation (SCDA) spatial availability index. Spatial availability is the amount of demand at the given location that can be satisfied by the supply of services at a facility, after discounting the intervening demand among other populations that are located nearer to a facility location than the given population location. This differs from spatial accessibility measures which treat absolute distance or travel time as the factor that impedes utilization. The SCDA is illustrated using pulmonary rehabilitation (PR), which is a treatment for people with chronic obstructive pulmonary disease (COPD). The spatial availability of PR was estimated for each Census block group in Georgia using the 1105 residents who utilized one of 45 PR facilities located in or around Georgia. Data was provided by the Centers for Medicare & Medicaid Services. The geographic patterns of the SCDA spatial availability index and the two-step floating catchment area (2SFCA) spatial accessibility index were compared with the observed PR utilization rate using bivariate local indicators of spatial association. The SCDA index was more associated with PR utilization (Morans I = 0.607, P < 0.001) than was the 2SFCA (Morans I = 0.321, P < 0.001). These results suggest that the measures of spatial availability may be a better way to estimate the health care utilization potential than measures of spatial accessibility.

Hospitalizations for Inflammatory Bowel Disease Among Medicare Fee-for-Service Beneficiaries - United States, 1999-2017.

Crohn's disease and ulcerative colitis, collectively referred to as inflammatory bowel disease (IBD), are conditions characterized by chronic inflammation of the gastrointestinal tract. The incidence and prevalence of IBD is increasing globally, and although the disease has little impact on mortality, the number of older adults with IBD is expected to increase as the U.S. population ages (1). Older adults with IBD have worse hospitalization outcomes than do their younger counterparts (2). CDC analyzed Medicare Provider Analysis and Review (MedPAR) data to estimate IBD-related hospitalization rates and hospitalization outcomes in 2017 among Medicare fee-for-service beneficiaries aged ≥65 years, by selected demographics and trends in hospitalization rates and by race/ethnicity during 1999-2017. In 2017, the age-adjusted hospitalization rate for Crohn's disease was 15.5 per 100,000 Medicare enrollees, and the IBD-associated surgery rate was 17.4 per 100 hospital stays. The age-adjusted hospitalization rate for ulcerative colitis was 16.2 per 100,000 Medicare enrollees, and the surgery rate was 11.2 per 100 stays. During 1999-2017, the hospitalization rate for both Crohn's disease and ulcerative colitis decreased among non-Hispanic white (white) beneficiaries, but not among non-Hispanic black (black) beneficiaries. Health care utilization assessment is needed among black beneficiaries with IBD. Disease management for older adults with IBD could focus on increasing preventive care and preventing emergency surgeries that might result in further complications.

Chronic Obstructive Pulmonary Disease and Smoking Status - United States, 2017.

Cigarette smoking is the leading cause of chronic obstructive pulmonary disease (COPD) in the United States; however, an estimated one fourth of adults with COPD have never smoked (1). CDC analyzed state-specific Behavioral Risk Factor Surveillance System (BRFSS) data from 2017, which indicated that, overall among U.S. adults, 6.2% (age-adjusted) reported having been told by a health care professional that they had COPD. The age-adjusted prevalence of COPD was 15.2% among current cigarette smokers, 7.6% among former smokers, and 2.8% among adults who had never smoked. Higher prevalences of COPD were observed in southeastern and Appalachian states, regardless of smoking status of respondents. Whereas the strong positive correlation between state prevalence of COPD and state prevalence of current smoking was expected among current and former smokers, a similar relationship among adults who had never smoked suggests secondhand smoke exposure as a potential risk factor for COPD. Continued promotion of smoke-free environments might reduce COPD among both those who smoke and those who do not.

Receipt of Preventive Care Services Among US Adults with Inflammatory Bowel Disease, 2015-2016.

BACKGROUND: Previous reports suggest that adults with inflammatory bowel disease (IBD) receive suboptimal preventive care. AIMS: The population-based study compared the receipt of these services by US adults with and without IBD. METHODS: Adults aged ≥ 18 years with IBD (1.2%) and without IBD were identified from the 2015 and 2016 National Health Interview Survey (n = 66,610). Age-standardized prevalence of doctor visits, receipt of medical advice, and selected preventive care was calculated for adults with and without IBD. The model-adjusted prevalence ratios were estimated for receipt of preventive care associated with IBD. RESULTS: The prevalence of a doctor visit in the past 12 months was significantly higher among adults with IBD than those without. IBD was also associated with significantly higher prevalence of receiving medical advice about smoking cessation (83.9% vs. 66.4%) and diet (42.9% vs. 32.1%), having colon cancer screening in the past 12 months (44.0% vs. 26.7%), having ever had an HIV test (51.5% vs. 45.4%) or pneumococcal vaccine (75.3% vs. 64.0%), having received a tetanus vaccine in the past 10 years (72.0% vs. 61.8%), and having received a flu vaccine in the past 12 months (48.4% vs. 41.0%), but was not significantly associated with receiving cervical cancer screening and hepatitis A and B vaccines. CONCLUSIONS: Adults with IBD were more likely to receive many types of preventive care than adults without IBD. The findings can inform healthcare policy makers to make strategic decisions that enhance multidisciplinary coordination from various medical specialties to ensure optimal preventive care for IBD patients.

Chronic Obstructive Pulmonary Disease and Arthritis Among US Adults, 2016.

INTRODUCTION: More than 54 million US adults have arthritis, and more than 15 million US adults have chronic obstructive pulmonary disease (COPD). Arthritis and COPD share many risk factors, such as tobacco use, asthma history, and age. The objective of this study was to assess the relationship between self-reported physician-diagnosed COPD and arthritis in the US adult population. METHODS: We analyzed data from 408,774 respondents aged 18 or older in the 2016 Behavioral Risk Factor Surveillance System to assess the association between self-reported physician-diagnosed COPD and arthritis in the US adult population by using multivariable logistic regression analyses. RESULTS: Overall crude prevalence was 6.4% for COPD and 25.2% for arthritis. The prevalence of age-adjusted COPD was higher among respondents with arthritis than among respondents without arthritis (13.7% vs 3.8%, P < .001). The association remained significant among most subgroups (P < .001) particularly among adults aged 18 to 44 (11.5% vs 2.0%) and never smokers (7.6% vs 1.7%). In multivariable logistic regression analyses, arthritis status was significantly associated with COPD status after controlling for sociodemographic characteristics, risk behaviors, and health-related quality of life measures (adjusted prevalence ratio = 1.5, 95% confidence interval, 1.4-1.5, P < .001). CONCLUSION: Our results confirmed that arthritis is associated with a higher prevalence of COPD in the US adult population. Health care providers may assess COPD and arthritis symptoms for earlier detection of each condition and recommend that patients with COPD and/or arthritis participate in pulmonary rehabilitation and self-management education programs such as the Chronic Disease Self-Management Program, the proven benefits of which include increased aerobic activity and reduced shortness of breath, pain, and depression.

Health-Risk Behaviors and Chronic Conditions Among Adults with Inflammatory Bowel Disease - United States, 2015 and 2016.

Inflammatory bowel disease (IBD), which includes Crohn's disease and ulcerative colitis, involves chronic inflammation of the gastrointestinal tract. In 2015, an estimated 3.1 million adults in the United States had ever received a diagnosis of IBD (1). Nationally representative samples of adults with IBD have been unavailable or too small to assess relationships between IBD and other chronic conditions and health-risk behaviors (2). To assess the prevalence of health-risk behaviors and chronic conditions among adults with and without IBD, CDC aggregated survey data from the 2015 and 2016 National Health Interview Survey (NHIS). An estimated 3.1 million (unadjusted lifetime prevalence = 1.3%) U.S. adults had ever received a diagnosis of IBD. Adults with IBD had a significantly lower prevalence of having never smoked cigarettes than did adults without the disease (55.9% versus 63.5%). Adults with IBD had significantly higher prevalences than did those without the disease in the following categories: having smoked and quit (26.0% versus 21.0%; having met neither aerobic nor muscle-strengthening activity guidelines (50.4% versus 45.2%); reporting <7 hours of sleep, on average, during a 24-hour period (38.2% versus 32.2%); and having serious psychological distress (7.4% versus 3.4%). In addition, nearly all of the chronic conditions evaluated were more common among adults with IBD than among adults without IBD. Understanding the health-risk behaviors and prevalence of certain chronic conditions among adults with IBD could inform clinical practice and lead to better disease management.

Short Sleep Duration Among Middle School and High School Students - United States, 2015.

Insufficient sleep among children and adolescents is associated with increased risk for obesity, diabetes, injuries, poor mental health, attention and behavior problems, and poor academic performance (1-4). The American Academy of Sleep Medicine has recommended that, for optimal health, children aged 6-12 years should regularly sleep 9-12 hours per 24 hours and teens aged 13-18 years should sleep 8-10 hours per 24 hours (1). CDC analyzed data from the 2015 national, state, and large urban school district Youth Risk Behavior Surveys (YRBSs) to determine the prevalence of short sleep duration (<9 hours for children aged 6-12 years and <8 hours for teens aged 13-18 years) on school nights among middle school and high school students in the United States. In nine states that conducted the middle school YRBS and included a question about sleep duration in their questionnaire, the prevalence of short sleep duration among middle school students was 57.8%, with state-level estimates ranging from 50.2% (New Mexico) to 64.7% (Kentucky). The prevalence of short sleep duration among high school students in the national YRBS was 72.7%. State-level estimates of short sleep duration for the 30 states that conducted the high school YRBS and included a question about sleep duration in their questionnaire ranged from 61.8% (South Dakota) to 82.5% (West Virginia). The large percentage of middle school and high school students who do not get enough sleep on school nights suggests a need for promoting sleep health in schools and at home and delaying school start times to permit students adequate time for sleep.

Urban-Rural County and State Differences in Chronic Obstructive Pulmonary Disease - United States, 2015.

Chronic obstructive pulmonary disease (COPD) accounts for the majority of deaths from chronic lower respiratory diseases, the third leading cause of death in the United States in 2015 and the fourth leading cause in 2016.* Major risk factors include tobacco exposure, occupational and environmental exposures, respiratory infections, and genetics.† State variations in COPD outcomes (1) suggest that it might be more common in states with large rural areas. To assess urban-rural variations in COPD prevalence, hospitalizations, and mortality; obtain county-level estimates; and update state-level variations in COPD measures, CDC analyzed 2015 data from the Behavioral Risk Factor Surveillance System (BRFSS), Medicare hospital records, and death certificate data from the National Vital Statistics System (NVSS). Overall, 15.5 million adults aged ≥18 years (5.9% age-adjusted prevalence) reported ever receiving a diagnosis of COPD; there were approximately 335,000 Medicare hospitalizations (11.5 per 1,000 Medicare enrollees aged ≥65 years) and 150,350 deaths in which COPD was listed as the underlying cause for persons of all ages (40.3 per 100,000 population). COPD prevalence, Medicare hospitalizations, and deaths were significantly higher among persons living in rural areas than among those living in micropolitan or metropolitan areas. Among seven states in the highest quartile for all three measures, Arkansas, Kentucky, Mississippi, and West Virginia were also in the upper quartile (≥18%) for rural residents. Overcoming barriers to prevention, early diagnosis, treatment, and management of COPD with primary care provider education, Internet access, physical activity and self-management programs, and improved access to pulmonary rehabilitation and oxygen therapy are needed to improve quality of life and reduce COPD mortality.
