Questions for Ana Terry, Health Statistician and Lead Author of “Seafood Consumption in the United States, 2013–2016”
Q: What surprised you most about the findings in your report?
AT: Although the findings were not necessarily surprising, we found that seafood consumption was more than twice as high among non-Hispanic Asian adults compared with adults of other race and Hispanic-origin groups. More than 40% of non-Hispanic Asian adults consumed seafood at least twice per week compared to about 19% of non-Hispanic white, 23% of non-Hispanic black, and 15% of Hispanic adults. This is consistent with other studies, which have found that people of Asian descent living in the U.S. consume seafood more frequently, in greater variety, and in greater quantity than non-Asian Americans (Liu et al, Environmental Research, October 2017).
Q: Do we know why there is such a disparity between US Asians and other race/ethnic groups when it comes to consuming the recommended amount of seafood?
AT: We analyzed data from the 2013-2016 National Health and Nutrition Examination Survey that was collected by a food frequency questionnaire in which persons were asked about the frequency and type of fish and shellfish they consumed in the previous 30 days. The questionnaire did not ask for the reasons why individuals consumed or did not consume seafood. Other studies have found that diet patterns in Asian countries include fish and shellfish intake levels greater than the average seafood consumption worldwide and that the food choices of people of Asian descent living in the U.S. , are influences by Asian dietary patterns (Liu et al, Environmental Research, October 2017).
Q: Does the fact that seafood consumption has declined mean the population is at less of a risk for mercury exposure?
AT: We did not assess mercury exposure in this report.
Q: What are the health benefits to eating seafood?
AT: The Dietary Guidelines for Americans recommend for the general population consumption of about 8 oz per week of a variety of seafood. Fish and shellfish are excellent sources of high quality protein, are low in saturated fat, are rich in minerals and vitamins, and provide certain omega-3 fatty acids (EPA and DHA) that the body cannot make and are important for normal growth and development. Seafood and omega-3 fatty acids have been shown to protect against health problems.
Q: What kinds of seafood are most healthy to eat?
AT: Cold water oily fish have the highest levels of omega-3 fatty acids but lower in methyl mercury (according to the 2015-2020 Dietary Guidelines for Americans). Cold water oily fish include: Salmon, Anchovies, Herring, Shad, Atlantic and Pacific mackerel
Questions for Lindsey Black, Health Statistician and Lead Author of “Chronic School Absenteeism Among Children With Selected Developmental Disabilities: National Health Interview Survey, 2014–2016”
Q: Why did you decide to focus on chronic school absenteeism among U.S. children with developmental disabilities for this report?
LB: DDs encompass a range of conditions that may have lifelong impacts on the functioning and wellbeing of children. In particular, developmental disabilities (DDs) can affect school adjustment, attendance and academic performance. Previous research has explored the relationships of DDs and school outcomes but have generally been limited in sample size and use aggregate mental health measures, rather than specific conditions.
This study aims to describe chronic school absenteeism among a nationally representative sample of children with selected DDs of autism spectrum disorder, intellectual disability, other developmental delay and attention-deficit/hyperactivity disorder (ADHD), in order to identify groups that may need additional supports.
Q: What is meant by chronic school absenteeism?
LB: School absenteeism was categorized based on the survey question, “During the past 12 months, about how many days did (sample child) miss school because of illness or injury?” Responses of 15 or more days were categorized as chronic school absenteeism based on the U.S. Department of Education definition.
Q: How did the findings vary among the selected developmental disabilities?
LB: In this nationally representative sample of children aged 5–17 years, children with ADHD, autism spectrum disorder, and intellectual disability were more likely to have had chronic school absenteeism compared with children who did not have these conditions even after controlling for demographic and selected physical health conditions.
Similarly, as the number of DDs increased, the DDs of chronic school absenteeism increased. These findings show that both the type and number of DDs are associated with school attendance.
Q: What methods did you use to conduct this analysis?
LB: We calculated the weighted percentage of children who had chronic school absenteeism for each of the selected developmental disability groups. Next, separate unadjusted logistic regressions for each of the selected DDs as the dependent variable (and chronic absenteeism as the outcome) were calculated. Multivariate logistic regressions were also used to assess the association between children with selected DDs and chronic school absenteeism, adjusted by selected demographic characteristics and co-occurring physical health conditions.
Q: Is there any comparable trend data on this topic from previous National Health Interview Service data?
LB: This is the first report that specifically looks at chronic school absenteeism among developmental disabilities. Data on number of school days missed due to illness or injury has been collected among children consistently since 1997.
Q: What is the take home message in this report?
LB: Children with DDs had higher chronic school absenteeism. Associations remained, controlling for demographics and co-occurring physical health conditions.
In 2016, 22% of current residents living in residential care communities had a fall in the past 90 days, representing 175,000 residents in the United States.
By region, 27% of residents living in communities in the Northeast, 23% of residents in Midwest communities, and 20% of residents in communities in the South and West, respectively, had a fall.
A higher percentage of residents in the Northeast had a fall compared with residents in the South and West.

Questions for Renee Gindi, Ph.D., Chief, Analytic Studies Branch, Office of Analysis and Epidemiology, who led production of “Health, United States, 2017”
Q: Why did you produce this report?
RG: We produced this report for a number of reasons. Health, United States, 2017 with Special Feature on Mortality is the 41st edition of the Congressionally-mandated annual report on the health of the nation from the Secretary of the Department of Health and Human Services to the President of the United States and to Congress.
This report benefits the public health community and the general public by bringing key national health data from different sources into one location. In this wide-ranging report, users can find graphs, tables, and descriptions of trends and current information on selected measures of health and disease. The Special Feature section of the report more closely examines a topic of public health interest and policy relevance.
Q: What made you decide to focus on deaths in the United States as the Special Feature for this study?
RG: It was the recent decrease in life expectancy at birth that caused us to want to look more deeply into what groups were most affected by this marked change. Life expectancy at birth decreased for the first time since 1993 by 0.2 years between 2014 and 2015 and then decreased another 0.1 years between 2015 and 2016. We found that between 2000 and 2016, death rates for 5 of the 12 leading causes of death increased: unintentional injuries, Alzheimer’s disease, suicide, chronic liver disease, and septicemia.
Q: Was there a finding in this edition of “Health, United States” that you hadn’t expected and that really surprised you?
RG: In addition to the decrease in life expectancy at birth, we found several trends that were particularly noteworthy. Here are a few of them:
Q: What is new in the report this year?
RG: There are a couple of new items worth highlighting from this year’s edition of Health, United States. The Special Feature on mortality, with its look at when, why, and where individuals are dying in the United States, is a new focus this year.
Also new this year is the examination of trends in disability and functional limitation using a new data source, the Washington Group Short Set on Functioning (WG-SS). These questions are considered the international standard and replace the questions used to describe disability in previous editions of Health, United States.
Health, United States, 2017 includes information on the functional status of civilian noninstitutionalized adults. Level of difficulty in six basic, universal domains—seeing, hearing, mobility, communication, cognition (remembering or concentrating), and self-care—identify the population with disability, namely those at greater risk than the general population for participation restrictions due to these, if appropriate accommodations are not made. Functional status is summarized using three mutually exclusive categories: “a lot of difficulty” or “cannot do at all/unable to do” in at least one domain; “some difficulty” in at least one domain but no higher level of difficulty in any domain; and those with “no difficulty” in all domains.
Q: What does this publication tell us about the health of our nation?
RG: This year’s Health, United States publication tells us a lot about the health of our nation. The overall age-adjusted death rate has decreased between 2006 and 2016 by 8%, from 791.8 to 728.8 deaths per 100,000 resident population. However, the majority of deaths (73%) are among persons aged 65 and older. The death rates for nearly all of the leading causes of death in this age group have been decreasing since 2006, including heart disease and cancer, the two leading causes of death in this age group.
However, the death rates in other age groups paint a different picture. Among persons aged 15-24, 25-44 and 45-64, death rates for several causes have been increasing in recent years—including unintentional injuries, suicide, homicide, and chronic liver disease.

Questions for Mark Eberhardt, Health Statistician and Lead Author of “Prevalence of Total, Diagnosed, and Undiagnosed Diabetes Among Adults: United States, 2013-2016”
Q: Why did you decide to focus on diabetes in the United States for this report?
ME: The National Health and Nutrition Examination Survey (NHANES) is the only nationally representative survey that can estimate undiagnosed diabetes, since more recent data are available to consider this subject, it was appropriate to present it.
Q: Can you explain the differences between diagnosed and undiagnosed diabetes?
ME: People with diagnosed diabetes are those who report a medical history of diabetes (that is, a health care provider previously told them that they have diabetes). People with undiagnosed diabetes are those who do not report a previous medical history of diabetes, but who have laboratory results from blood specimens obtaining in NHANES which are in the diabetic range, as defined by the American Diabetes Association.
Q: How did the findings vary by sex, age, race and weight?
ME: The percent of adults with diabetes increases with age; a higher percent of men, compared to women, have total diabetes (which includes diagnosed and undiagnosed diabetes); a higher percent of non-Hispanic black and Hispanic adults have diabetes and total diabetes compared to non-Hispanic white adults. The percent of adults with diabetes (diagnosed, undiagnosed, or total diabetes) is higher among those who are overweight or obese.
Q: How did you obtain this data?
ME: The data were obtained in 2013-2016 by NHANES. This is a population-based community health survey conducted by the National Center for Health Statistics, Centers for Disease Control and Prevention (CDC). NHANES has staff and mobile examination centers that travel around the US and obtain health-related interview, examination and laboratory information from a nationally representative sample of people in the US.
Q: What is the take home message in this report?
ME: Diabetes remains a serious common health condition among adults in the US, and a substantial percent of adults with diabetes still report not having it.
