Are there seasonal patterns for emergency department visits for head injuries in the USA? Findings from the National Electronic Injury Surveillance System-All Injury Program.

INTRODUCTION: Previous international research suggests that the incidence of head injuries may follow seasonal patterns. However, there is limited information about how the numbers and rates of head injuries, particularly sports- and recreation-related head injuries, among adults and children evaluated in the emergency department (ED) vary by month in the USA. This information would provide the opportunity for tailored prevention strategies. METHODS: We analysed data from the National Electronic Injury Surveillance System-All Injury Program from 2016 to 2019 to examine both monthly variation of ED visit numbers and rates for head injuries overall and those due to sports and recreation. RESULTS: The highest number of head injuries evaluated in the ED occurred in October while the lowest number occurred in February. Among males, children ages 0-4 years were responsible for the highest rates of head injury-related ED visits each year, while in females the highest rates were seen in both children ages 0-4 and adults ages 65 and older. The highest number of head injuries evaluated in the ED due to sports and recreation were seen in September and October. Head injury-related ED visits due to sports and recreation were much more common in individuals ages 5-17 than any other age group. CONCLUSION: This study showed that head injury-related ED visits for all mechanisms of injury, as well as those due to sports- and recreation-related activities, followed predictable patterns-peaking in the fall months. Public health professionals may use study findings to improve prevention efforts and to optimise the diagnosis and management of traumatic brain injury and other head injuries.

Emergency Department Visits for Alcohol-Associated Falls Among Older Adults in the United States, 2011 to 2020.

STUDY OBJECTIVE: The aim of this study was to examine the epidemiology of alcohol-associated fall injuries among older adults aged ≥65 years in the United States. METHODS: We included emergency department (ED) visits for unintentional fall injuries by adults from the National Electronic Injury Surveillance System-All Injury Program during 2011 to 2020. We estimated the annual national rate of ED visits for alcohol-associated falls and the proportion of these falls among older adults' fall-related ED visits using demographic and clinical characteristics. Joinpoint regression was performed to examine trends in alcohol-associated ED fall visits between 2011 and 2019 among older adult age subgroups and to compare these trends with those of younger adults. RESULTS: There were 9,657 (weighted national estimate: 618,099) ED visits for alcohol-associated falls, representing 2.2% of ED fall visits during 2011 to 2020 among older adults. The proportion of fall-related ED visits that were alcohol-associated was higher among men than among women (adjusted prevalence ratio [aPR]=3.6, 95% confidence interval [CI] 2.9 to 4.5). The head and face were the most commonly injured body parts, and internal injury was the most common diagnosis for alcohol-associated falls. From 2011 to 2019, the annual rate of ED visits for alcohol-associated falls increased (annual percent change 7.5, 95% CI 6.1 to 8.9) among older adults. Adults aged 55 to 64 years had a similar increase; a sustained increase was not detected in younger age groups. CONCLUSION: Our findings highlight the rising rates of ED visits for alcohol-associated falls among older adults during the study period. Health care providers in the ED can screen older adults for fall risk and assess for modifiable risk factors such as alcohol use to help identify those who could benefit from interventions to reduce their risk.

Child abuse-related homicides precipitated by caregiver use of harsh physical punishment.

BACKGROUND: Physical punishment (PP), which may involve the use of physical force, has been linked to negative effects in children and can escalate to abusive or harsh PP, resulting in injury or death. OBJECTIVE: To examine characteristics associated with fatal abuse involving caregiver use of harsh PP. METHODS: Data were from the National Violent Death Reporting System in 40 states, the District of Columbia, and Puerto Rico for years 2012-2018. Qualitative analysis was used to code textual material into categorial data, and logistic regression was used to examine associations between various characteristics and harsh PP. RESULTS: Approximately 4 % (n = 87) of the 2414 abuse-related homicides were known to have been precipitated by caregiver use of harsh PP. In adjusted models, homicides had greater odds of being harsh PP-related when incidents involved mothers' male companions (versus fathers), victims had a previous nonfatal injury (versus no previous nonfatal injury), and another adult participated in the fatal incident or had awareness of prior abuse/neglect (versus those without this characteristic). Two common precipitators of caregivers' use of harsh PP were: 1) child had a bathroom-related accident/soiled clothes (23.0 %; n = 20), and 2) child disobeyed a directive given by the perpetrator (17.2 %; n = 15). CONCLUSIONS: This study highlights characteristics associated with fatal abuse precipitated by caregiver use of harsh PP. Children were physically punished for developmentally normative behaviors. Ensuring caregivers are aware of and use effective parenting practices that focus on use of nonphysical discipline and promote healthy child development, may help decrease harsh PP and physical abuse-related homicides among children.

Neonaticides in the United States-2008-2017.

Objective: This study examines factors associated with homicide in the first 24 hours of life (i.e., neonaticide) in the United States. Methods: National Vital Statistics System (NVSS) linked birth-infant death data, for 50 states and the District of Columbia, from 2008 through 2017, were used to examine characteristics associated with neonaticide. National Violent Death Reporting System (NVDRS) data were used to examine circumstances of neonaticides that occurred in 14 states. Circumstances of neonaticides are described, and rates for maternal and infant characteristics are presented as rates per 100,000 person-years. Results: Among neonaticide victims in NVSS (N = 81), those of mothers who are young, unmarried, non-Hispanic, Black, and have lower education levels, are at an increased risk of neonaticide. Further, among mothers in NVDRS who committed neonaticide (N = 42), 66.7% were known to have given birth at a residence, without medical assistance. Approximately three-fourths (73.8%; n = 31) concealed their pregnancy, with 35.7% (n = 15) disposing of their infants in a trash receptacle after giving birth. Additionally, more than half of neonaticide victims were tested for alcohol, opioids, amphetamines, and cocaine, but a relatively small number tested positive for these substances. Conclusions: Results highlight the importance of identifying factors that elevate risk to neonates so these deaths can be prevented. As such, many mothers who commit neonaticide are young, unmarried, and conceal their pregnancy; thus, programs that prevent teen pregnancy, decrease shame and stigma associated with birth to young mothers, and provide support and resources to pregnant women, may help prevent neonaticide.

Injury-Related Emergency Department Visits During the COVID-19 Pandemic.

INTRODUCTION: On March 13, 2020, the U.S. declared COVID-19 to be a national emergency. As communities adopted mitigation strategies, there were potential changes in the trends of injuries treated in emergency department. This study provides national estimates of injury-related emergency department visits in the U.S. before and during the pandemic. METHODS: A secondary retrospective cohort study was conducted using trained, on-site hospital coders collecting data for injury-related emergency department cases from medical records from a nationally representative sample of 66 U.S. hospital emergency departments. Injury emergency department visit estimates in the year before the pandemic (January 1, 2019-December 31, 2019) were compared with estimates of the year of pandemic declaration (January 1, 2020-December 31, 2020) for overall nonfatal injury-related emergency department visits, motor vehicle, falls-related, self-harm-, assault-related, and poisoning-related emergency department visits. RESULTS: There was an estimated 1.7 million (25%) decrease in nonfatal injury-related emergency department visits during April through June 2020 compared with those of the same timeframe in 2019. Similar decreases were observed for emergency department visits because of motor vehicle‒related injuries (199,329; 23.3%) and falls-related injuries (497,971; 25.1%). Monthly 2020 estimates remained relatively in line with 2019 estimates for self-harm‒, assault-, and poisoning-related emergency department visits. CONCLUSIONS: These findings provide updates for clinical and public health practitioners on the changing profile of injury-related emergency department visits during the COVID-19 pandemic. Understanding the short- and long-term impacts of the pandemic is important to preventing future injuries.

Examining differences between mass, multiple, and single-victim homicides to inform prevention: findings from the National Violent Death Reporting System.

BACKGROUND: Multi-victim homicides are a persistent public health problem confronting the United States. Previous research shows that homicide rates in the U.S. are approximately seven times higher than those of other high-income countries, driven by firearm homicide rates that are 25 times higher; 31% of public mass shootings in the world also occur in the U.S.. The purpose of this analysis is to examine the characteristics of mass, multiple, and single homicides to help identify prevention points that may lead to a reduction in different types of homicides. METHODS: We used all available years (2003-2017) and U.S. states/jurisdictions (35 states, the District of Columbia, and Puerto Rico) included in CDC's National Violent Death Reporting System (NVDRS), a public health surveillance system which combines death certificate, coroner/medical examiner, and law enforcement reports into victim- and incident-level data on violent deaths. NVDRS includes up to 600 standard variables per incident; further information on types of mental illness among suspected perpetrators and incident resolution was qualitatively coded from case narratives. Data regarding number of persons nonfatally shot within incidents were cross-validated when possible with several other resources, including government reports and the Gun Violence Archive. Mass homicides (4+ victims), multiple homicides (2-3 victims) and single homicides were analyzed to assess group differences using Chi-square tests with Bonferroni-corrected post-hoc comparisons. RESULTS: Mass homicides more often had female, child, and non-Hispanic white victims than other homicide types. Compared with victims of other homicide types, victims of mass homicides were more often killed by strangers or someone else they did not know well, or by family members. More than a third were related to intimate partner violence. Approximately one-third of mass homicide perpetrators had suicidal thoughts/behaviors noted in the time leading up to the incident. Multi-victim homicides were more often perpetrated with semi-automatic firearms than single homicides. When accounting for nonfatally shot victims, over 4 times as many incidents could have resulted in mass homicide. CONCLUSIONS: These findings underscore the important interconnections among multiple forms of violence. Primary prevention strategies addressing shared risk and protective factors are key to reducing these incidents.

Surveillance for Violent Deaths - National Violent Death Reporting System, 32 States, 2016.

PROBLEM/CONDITION: In 2016, approximately 65,000 persons died in the United States as a result of violence-related injuries. This report summarizes data from CDC's National Violent Death Reporting System (NVDRS) regarding violent deaths from 32 U.S. states for 2016. Results are reported by sex, age group, race/ethnicity, type of location where injured, method of injury, circumstances of injury, and other selected characteristics. PERIOD COVERED: 2016. DESCRIPTION OF SYSTEM: NVDRS collects data regarding violent deaths obtained from death certificates, coroner/medical examiner reports, law enforcement reports, and secondary sources (e.g., child fatality review team data, Supplementary Homicide Reports, hospital data, and crime laboratory data). This report includes data collected from 32 states for 2016 (Alaska, Arizona, Colorado, Connecticut, Georgia, Hawaii, Illinois, Indiana, Iowa, Kansas, Kentucky, Maine, Maryland, Massachusetts, Michigan, Minnesota, New Hampshire, New Jersey, New Mexico, New York, North Carolina, Ohio, Oklahoma, Oregon, Pennsylvania, Rhode Island, South Carolina, Utah, Vermont, Virginia, Washington, and Wisconsin). NVDRS collates information for each death and links deaths that are related (e.g., multiple homicides, homicide followed by suicide, or multiple suicides) into a single incident. RESULTS: For 2016, NVDRS captured 40,374 fatal incidents involving 41,466 deaths in the 32 states included in this report. The majority (62.3%) of deaths were suicides, followed by homicides (24.9%), deaths of undetermined intent (10.8%), legal intervention deaths (1.2%) (i.e., deaths caused by law enforcement and other persons with legal authority to use deadly force acting in the line of duty, excluding legal executions), and unintentional firearm deaths (<1.0%). (The term legal intervention is a classification incorporated into the International Classification of Diseases, Tenth Revision [ICD-10] and does not denote the lawfulness or legality of the circumstances surrounding a death caused by law enforcement.) Demographic patterns varied by manner of death. Suicide rates were highest among males, non-Hispanic American Indians/Alaska Natives, non-Hispanic whites, adults aged 45-64 years, and men aged ≥75 years. The most common method of injury was a firearm among males and poisoning among females. Suicides were most often preceded by a mental health, intimate partner, substance abuse, or physical health problem or a recent or impending crisis during the previous or upcoming 2 weeks. Homicide rates were highest among males and persons aged <1 year and 15-44 years. Among males, non-Hispanic blacks accounted for most homicides and had the highest rate of any racial/ethnic group. The most common method of injury was a firearm. Homicides were most often precipitated by an argument or conflict, occurred in conjunction with another crime, or for females, were related to intimate partner violence. When the relationship between a homicide victim and a suspected perpetrator was known, the suspect was most frequently an acquaintance/friend among males and a current or former intimate partner among females. Legal intervention death rates were highest among men aged 20-44 years, and the rate among non-Hispanic black males was three times the rate among non-Hispanic white males. Precipitating circumstances for legal intervention deaths most frequently were an alleged criminal activity in progress, reported use of a weapon by the victim in the incident, a mental health or substance abuse problem (other than alcohol abuse), an argument or conflict, or a recent or impending crisis. Unintentional firearm deaths were more frequent among males, non-Hispanic whites, and persons aged 15-24 years. These deaths most often occurred while the shooter was playing with a firearm and most often were precipitated by a person unintentionally pulling the trigger or mistakenly thinking the firearm was unloaded. Rates of deaths of undetermined intent were highest among males, particularly non-Hispanic black and American Indian/Alaska Native males, and adults aged 25-64 years. Substance abuse, mental health problems, physical health problems, and a recent or impending crisis were the most common circumstances preceding deaths of undetermined intent. In 2016, a total of 3,655 youths aged 10-24 years died by suicide. The majority of these decedents were male, non-Hispanic white, and aged 18-24 years. Most decedents aged 10-17 years died by hanging/strangulation/suffocation (49.3%), followed by a firearm (40.4%), and suicides among this age group were most often precipitated by mental health, family relationship, and school problems. Most suicides among decedents aged 18-24 years were by a firearm (46.2%), followed by hanging/strangulation/suffocation (37.4%), and were precipitated by mental health, substance abuse, intimate partner, and family problems. A recent crisis, an argument or conflict, or both were common precipitating circumstances among all youth suicide decedents. INTERPRETATION: This report provides a detailed summary of data from NVDRS for 2016. Suicides rates were highest among non-Hispanic American Indian/Alaska Native and white males, whereas homicide rates were highest among non-Hispanic black males. Mental health problems, intimate partner problems, interpersonal conflicts, and acute life stressors were primary precipitating events for multiple types of violent deaths, including suicides among youths aged 10-24 years. PUBLIC HEALTH ACTION: NVDRS data are used to monitor the occurrence of violence-related fatal injuries and assist public health authorities in the development, implementation, and evaluation of programs and policies to reduce and prevent violent deaths. For example, Utah VDRS data were used to help identify suicide risk factors among youths aged 10-17 years, Rhode Island VDRS suicide data were analyzed to identify precipitating circumstances of youth suicides over a 10-year period, and Kansas VDRS data were used by the Kansas Youth Suicide Prevention Task Force. In 2019, NVDRS expanded data collection to include all 50 states, Puerto Rico, and the District of Columbia. This expansion is essential to public health efforts to reduce violent deaths.

Chronic Pain Among Suicide Decedents, 2003 to 2014: Findings From the National Violent Death Reporting System.

Background: More than 25 million adults in the United States have chronic pain. Chronic pain has been associated with suicidality, but previous studies primarily examined nonfatal suicidal behaviors rather than suicide deaths associated with chronic pain or the characteristics of such deaths. Objective: To estimate the prevalence of chronic pain among suicide decedents in a large multistate sample and to characterize suicide decedents with and without chronic pain. Design: Retrospective analysis of National Violent Death Reporting System (NVDRS) data. The NVDRS links death certificate, coroner or medical examiner, and law enforcement data collected by investigators, who often interview informants who knew the decedent to gather information on precipitating circumstances surrounding the suicide. Information is abstracted by using standard coding guidance developed by the Centers for Disease Control and Prevention. Setting: 18 states participating in the NVDRS. Participants: Suicide decedents with and without chronic pain who died during 1 January 2003 to 31 December 2014. Measurements: Demographic characteristics, mechanism of death, toxicology results, precipitating circumstances (mental health, substance use, interpersonal problems, life stressors), and suicide planning and intent. Results: Of 123 181 suicide decedents included in the study, 10 789 (8.8%) had evidence of chronic pain, and the percentage increased from 7.4% in 2003 to 10.2% in 2014. More than half (53.6%) of suicide decedents with chronic pain died of firearm-related injuries and 16.2% by opioid overdose. Limitation: The results probably underrepresent the true percentage of suicide decedents who had chronic pain, given the nature of the data and how they were captured. Conclusion: Chronic pain may be an important contributor to suicide. Access to quality, comprehensive pain care and adherence to clinical guidelines may help improve pain management and patient safety. Primary Funding Source: None.

Vital Signs: Trends in State Suicide Rates - United States, 1999-2016 and Circumstances Contributing to Suicide - 27 States, 2015.

INTRODUCTION: Suicide rates in the United States have risen nearly 30% since 1999, and mental health conditions are one of several factors contributing to suicide. Examining state-level trends in suicide and the multiple circumstances contributing to it can inform comprehensive state suicide prevention planning. METHODS: Trends in age-adjusted suicide rates among persons aged ≥10 years, by state and sex, across six consecutive 3-year periods (1999-2016), were assessed using data from the National Vital Statistics System for 50 states and the District of Columbia. Data from the National Violent Death Reporting System, covering 27 states in 2015, were used to examine contributing circumstances among decedents with and without known mental health conditions. RESULTS: During 1999-2016, suicide rates increased significantly in 44 states, with 25 states experiencing increases >30%. Rates increased significantly among males and females in 34 and 43 states, respectively. Fifty-four percent of decedents in 27 states in 2015 did not have a known mental health condition. Among decedents with available information, several circumstances were significantly more likely among those without known mental health conditions than among those with mental health conditions, including relationship problems/loss (45.1% versus 39.6%), life stressors (50.5% versus 47.2%), and recent/impending crises (32.9% versus 26.0%), but these circumstances were common across groups. CONCLUSIONS: Suicide rates increased significantly across most states during 1999-2016. Various circumstances contributed to suicides among persons with and without known mental health conditions. IMPLICATIONS FOR PUBLIC HEALTH PRACTICE: States can use a comprehensive evidence-based public health approach to prevent suicide risk before it occurs, identify and support persons at risk, prevent reattempts, and help friends and family members in the aftermath of a suicide.

Association of Birthplace and Coronary Heart Disease and Stroke Among US Adults: National Health Interview Survey, 2006 to 2014.

BACKGROUND: The proportion of foreign-born US adults has almost tripled since 1970. However, less is known about the cardiovascular morbidity by birthplace among adults residing in the United States. This study's objective was to compare the prevalence of coronary heart disease (CHD) and stroke among US adults by birthplace. METHODS AND RESULTS: We used data from the 2006 to 2014 National Health Interview Survey. Birthplace was categorized as United States or foreign born. Foreign born was then grouped into 6 birthplace regions. We defined CHD and stroke as ever being told by a physician that she or he had CHD or stroke. We adjusted for select demographic and health characteristics in the analysis. Of US adults, 16% were classified as foreign born. Age-standardized prevalence of both CHD and stroke were higher among US- than foreign-born adults (CHD: 8.2% versus 5.5% for men and 4.8% versus 4.1% for women; stroke: 2.7% versus 2.1% for men and 2.7% versus 1.9% for women; all P<0.05). Comparing individual regions with those of US- born adults, CHD prevalence was lower among foreign-born adults from Asia and Mexico, Central America, or the Caribbean. For stroke, although men from South America or Africa had the lowest prevalence, women from Europe had the lowest prevalence. Years of living in the United States was not related to risk of CHD or stroke after adjustment with demographic and health characteristics. CONCLUSIONS: Overall, foreign-born adults residing in the United States had a lower prevalence of CHD and stroke than US-born adults. However, considerable heterogeneity of CHD and stroke risk was found by region of birth.

Modeled changes in US sodium intake from reducing sodium concentrations of commercially processed and prepared foods to meet voluntary standards established in North America: NHANES.

Background: Approximately 2 in 3 US adults have prehypertension or hypertension that increases their risk of cardiovascular disease. Reducing sodium intake can decrease blood pressure and prevent hypertension. Approximately 9 in 10 Americans consume excess sodium (≥2300 mg/d). Voluntary sodium standards for commercially processed and prepared foods were established in North America, but their impact on sodium intake is unclear.Objective: We modelled the potential impact on US sodium intake of applying voluntary sodium standards for foods.Design: We used NHANES 2007-2010 data for 17,933 participants aged ≥1 y to model predicted US daily mean sodium intake and the prevalence of excess sodium intake with the use of the standards of the New York City's National Salt Reduction Initiative (NSRI) and Health Canada for commercially processed and prepared foods. The Food and Nutrient Database for Dietary Studies food codes corresponding to foods reported by NHANES participants were matched to NSRI and Health Canada food categories, and the published sales-weighted mean percent reductions were applied.Results: The US population aged ≥1 y could have reduced their usual daily mean sodium intake of 3417 mg by 698 mg (95% CI: 683, 714 mg) by applying NSRI 2014 targets and by 615 mg (95% CI: 597, 634 mg) by applying Health Canada's 2016 benchmarks. Significant reductions could have occurred, regardless of age, sex, race/ethnicity, income, education, or hypertension status, up to a mean reduction in sodium intake of 850 mg/d in men aged ≥19 y by applying NSRI targets. The proportion of adults aged ≥19 y who consume ≥2300 mg/d would decline from 88% (95% CI: 86%, 91%) to 71% (95% CI: 68%, 73%) by applying NSRI targets and to 74% (95% CI: 71%, 76%) by applying Health Canada benchmarks.Conclusion: If established sodium standards are applied to commercially processed and prepared foods, a significant reduction of US sodium intake could occur.

Sources of Sodium in US Adults From 3 Geographic Regions.

BACKGROUND: Most US adults consume excess sodium. Knowledge about the dietary sources of sodium intake is critical to the development of effective reduction strategies. METHODS: A total of 450 adults were recruited from 3 geographic locations: Birmingham, AL (n=150); Palo Alto, CA (n=150); and the Minneapolis-St. Paul, MN (n=150), metropolitan areas. Equal numbers of women and men from each of 4 race/ethnic groups (blacks, Asians, Hispanics, and non-Hispanic whites) were targeted for recruitment. Four record-assisted 24-hour dietary recalls were collected from each participant with special procedures, which included the collection of duplicate samples of salt added to food at the table and in home food preparation. RESULTS: Sodium added to food outside the home was the leading source of sodium, accounting for more than two thirds (70.9%) of total sodium intake in the sample. Although the proportion of sodium from this source was smaller in some subgroups, it was the leading contributor for all subgroups. Contribution ranged from 66.3% for those with a high school level of education or less to 75.0% for those 18 to 29 years of age. Sodium inherent to food was the next highest contributor (14.2%), followed by salt added in home food preparation (5.6%) and salt added to food at the table (4.9%). Home tap water consumed as a beverage and dietary supplement and nonprescription antacids contributed minimally to sodium intake (<0.5% each). CONCLUSIONS: Sodium added to food outside the home accounted for ≈70% of dietary sodium intake. This finding is consistent with the 2010 Institute of Medicine recommendation for reduction of sodium in commercially processed foods as the primary strategy to reduce sodium intake in the United States.

Sodium, sugar, and fat content of complementary infant and toddler foods sold in the United States, 2015.

Background: As part of a healthy diet, limiting intakes of excess sodium, added sugars, saturated fat, and trans fat has been recommended. The American Heart Association recommends that children aged <2 y should avoid added sugars.Objective: We sought to determine commercial complementary infant-toddler food categories that were of potential concern because of the sodium, added sugar, saturated fat, or trans fat content.Design: Nutrition label information (e.g., serving size, sodium, saturated fat, trans fat) for 1032 infant and toddler foods was collected from manufacturers' websites and stores from May to July 2015 for 24 brands, which accounted for >95% of infant-toddler food sales. The presence of added sugars was determined from the ingredient list. Reference amount customarily consumed (RACC) categories were used to group foods and standardize serving sizes. A high sodium content was evaluated on the basis of the Upper Intake Level for children aged 1-3 y and the number of potential servings per day ([i.e., 1500 mg/7 servings (>210 mg/RACC)], a sodium amount >200 mg/100 g, or a mean sodium density >1000 mg/1000 kcal.Results: In 2015, most commercial infant-only vegetables, fruit, dinners, and cereals were low in sodium, contained no saturated fat, and did not contain added sugars. On average, toddler meals contained 2233 mg Na/1000 kcal, and 84% of the meals had >210 mg Na/RACC (170 g), whereas 69% of infant-toddler savory snacks had >200 mg Na/100 g. More than 70% of toddler meals, cereal bars and breakfast pastries, and infant-toddler grain- or dairy-based desserts contained ≥1 sources of added sugar. Approximately 70% of toddler meals contained saturated fat (mean: 1.9 g/RACC), and no commercial infant-toddler foods contained trans fats.Conclusion: Most commercial toddler meals, cereal bars and breakfast pastries, and infant-toddler snacks and desserts have high sodium contents or contain added sugars, suggesting a need for continued public health efforts to support parents in choosing complementary foods for their infants and toddlers.

Risk of Skin and Soft Tissue Infections among Children Found to be Staphylococcus aureus MRSA USA300 Carriers.

INTRODUCTION: The purpose of this study was to examine community-associated methicillin resistant Staphylococcus aureus (CA-MRSA) carriage and infections and determine risk factors associated specifically with MRSA USA300. METHODS: We conducted a case control study in a pediatric emergency department. Nasal and axillary swabs were collected, and participants were interviewed for risk factors. The primary outcome was the proportion of S. aureus carriers among those presenting with and without a skin and soft tissue infection (SSTI). We further categorized S. aureus carriers into MRSA USA300 carriers or non-MRSA USA300 carriers. RESULTS: We found the MRSA USA300 carriage rate was higher in children less than two years of age, those with an SSTI, children with recent antibiotic use, and those with a family history of SSTI. MRSA USA300 carriers were also more likely to have lower income compared to non-MRSA USA300 carriers and no S. aureus carriers. Rates of Panton-Valentine leukocidin (PVL) genes were higher in MRSA carriage isolates with an SSTI, compared to MRSA carriage isolates of patients without an SSTI. There was an association between MRSA USA300 carriage and presence of PVL in those diagnosed with an abscess. CONCLUSION: Children younger than two years were at highest risk for MRSA USA300 carriage. Lower income, recent antibiotic use, and previous or family history of SSTI were risk factors for MRSA USA300 carriage. There is a high association between MRSA USA300 nasal/axillary carriage and presence of PVL in those with abscesses.

Do Lower Calorie or Lower Fat Foods Have More Sodium Than Their Regular Counterparts?

The objective of this study was to compare the sodium content of a regular food and its lower calorie/fat counterpart. Four food categories, among the top 20 contributing the most sodium to the US diet, met the criteria of having the most matches between regular foods and their lower calorie/fat counterparts. A protocol was used to search websites to create a list of "matches", a regular and comparable lower calorie/fat food(s) under each brand. Nutrient information was recorded and analyzed for matches. In total, 283 matches were identified across four food categories: savory snacks (N = 44), cheese (N = 105), salad dressings (N = 90), and soups (N = 44). As expected, foods modified from their regular versions had significantly reduced average fat (total fat and saturated fat) and caloric profiles. Mean sodium content among modified salad dressings and cheeses was on average 8%-12% higher, while sodium content did not change with modification of savory snacks. Modified soups had significantly lower mean sodium content than their regular versions (28%-38%). Consumers trying to maintain a healthy diet should consider that sodium content may vary in foods modified to be lower in calories/fat.

Development and Validation of a Hypertension Prevalence Estimator Tool For Use in Clinical Settings.

Health systems are well positioned to identify and control hypertension among their patients. However, almost one third of US adults with uncontrolled hypertension are currently receiving medical care and are unaware of being hypertensive. This study describes the development and validation of a tool that health systems can use to compare their reported hypertension prevalence with their expected prevalence. Tool users provide the number of patients aged 18 to 85 years treated annually, stratified by sex, age group, race/ethnicity, and comorbidity status. Each stratum is multiplied by stratum-specific national prevalence estimates and the amounts are summed to calculate the number of expected hypertensive patients. The tool's validity was assessed by applying samples from cohorts with known hypertension prevalence; small differences in expected vs actual prevalence were identified (range, -3.3% to 0.6%). This tool provides clinically useful hypertension prevalence estimates that health systems can use to help inform hypertension management quality improvement efforts.

Sodium Content of Foods Contributing to Sodium Intake: Comparison between Selected Foods from the CDC Packaged Food Database and the USDA National Nutrient Database for Standard Reference.

The sodium concentration (mg/100g) for 23 of 125 Sentinel Foods (e.g. white bread) were identified in the 2009 CDC Packaged Food Database (PFD) and compared with data in the USDA's 2013 National Nutrient Database for Standard Reference(SR 26). Sentinel Foods are foods identified by USDA to be monitored as primary indicators to assess the changes in the sodium content of commercially processed foods from stores and restaurants. Overall, 937 products were evaluated in the CDC PFD, and between 3 (one brand of ready-to-eat cereal) and 126 products (white bread) were evaluated per selected food. The mean sodium concentrations of 17 of the 23 (74%) selected foods in the CDC PFD were 90%-110% of the mean sodium concentrations in SR 26 and differences in sodium concentration were statistically significant for 6 Sentinel Foods. The sodium concentration of most of the Sentinel Foods, as selected in the PFD, appeared to represent the sodium concentrations of the corresponding food category. The results of our study help improve the understanding of how nutrition information compares between national analytic values and the label and whether the selected Sentinel Foods represent their corresponding food category as indicators for assessment of change of the sodium content in the food supply.

Sodium content in packaged foods by census division in the United States, 2009.

Excess sodium intake correlates positively with high blood pressure. Blood pressure varies by region, but whether sodium content of foods sold varies across regions is unknown. We combined nutrition and sales data from 2009 to assess the regional variation of sodium in packaged food products sold in 3 of the 9 US census divisions. Although sodium density and concentration differed little by region, fewer than half of selected food products met Food and Drug Administration sodium-per-serving conditions for labeling as "healthy." Regional differences in hypertension were not reflected in differences in the sodium content of packaged foods from grocery stores.

Top sources of dietary sodium from birth to age 24 mo, United States, 2003-2010.

BACKGROUND: Sodium intake is high in US children. Data are limited on the dietary sources of sodium, especially from birth to age 24 mo. OBJECTIVE: We identified top sources of dietary sodium in US children from birth to age 24 mo. DESIGN: Data from the NHANES 2003-2010 were used to examine food sources of sodium (population proportions and mean intakes) in 778 participants aged 0-5.9 mo, 914 participants aged 6-11.9 mo, and 1219 participants aged 12-23.9 mo by sociodemographic characteristics. RESULTS: Overall, mean dietary sodium intake was low in 0-5.9-mo-old children, and the top contributors were formula (71.7%), human milk (22.9%), and commercial baby foods (2.2%). In infants aged 6-11.9 mo, the top 5 contributors were formula (26.7%), commercial baby foods (8.8%), soups (6.1%), pasta mixed dishes (4.0%), and human milk (3.9%). In children aged 12-23.9 mo, the top contributors were milk (12.2%), soups (5.4%), cheese (5.2%), pasta mixed dishes (5.1%), and frankfurters and sausages (4.6%). Despite significant variation in top food categories across racial/ethnic groups, commercial baby foods were a top food contributor in children aged 6-11.9 mo, and frankfurters and sausages were a top food contributor in children aged 12-23.9 mo. The top 5 food categories that contributed to sodium intake also differed by sex. Most of the sodium consumed (83-90%) came from store foods (e.g., from the supermarket). In children aged 12-23.9 mo, 9% of sodium consumed came from restaurant foods, and 4% of sodium came from childcare center foods. CONCLUSIONS: The vast majority of sodium consumed comes from foods other than infant formula or human milk after the age of 6 mo. Although the majority of sodium intake was from store foods, after age 12 mo, restaurant foods contribute significantly to intake. Reducing the sodium content in these settings would reduce sodium intake in the youngest consumers.
