STATCAST, FEBRUARY 2021: DISCUSSION WITH TAINYA CLARKE, A STATISTICIAN WITH NHIS, ABOUT LATEST QUARTERLY NHIS EARLY RELEASE KEY HEALTH INDICATOR ESTIMATES.<\/strong><\/p>\n

HOST:<\/strong>\u00a0 This week NCHS released its latest quarterly estimates on a number of key health indicators from the National Health Interview Survey, one of the oldest health surveys in US history dating back to 1957. This latest quarterly release covers the period up to the midpoint of 2020.\u00a0 Health data from NHIS have always been driven by the types of questions asked in this traditionally in-person survey and in order to improve the quality of data the survey has been redesigned on occasion over the years, most recently in 2019. Tainya Clarke, an epidemiologist with the survey, elaborates:<\/p>\n

TAINYA CLARKE:<\/strong>\u00a0\u00a0 The NHIS underwent a survey redesign to better meet the needs of data users.\u00a0 Some questions were dropped from the survey, new questions were added, and some question text or the order they appear changed.\u00a0 All these changes mean that the NHIS survey for 2019 going forward is quite distinct from the past survey.\u00a0 In addition to the questionnaire design, changes made to the weighting approach have the potential to impact direct comparisons between the estimates for 2019 to June 2020 and earlier years.\u00a0 Because of this we have not examined trends prior to 2019 in this release.<\/p>\n

HOST:<\/strong>\u00a0 The last time the NHIS was redesigned was in 1997.\u00a0 That redesign laid the foundation for the creation of the early release program, which features quarterly preliminary estimates on a number of high profile health topics.\u00a0 The 2019 redesign introduced several new topics to the survey.\u00a0 However, the arrival of the pandemic in 2020 forced more changes to the way the survey operates, which in turn has had an impact on response rates:<\/p>\n

TAINYA CLARKE:<\/strong>\u00a0\u00a0 \u00a0Due to the current pandemic and the need for physical distancing, in quarter two we switched to a telephone-only approach, and in quarter three and four a telephone-first approach and followed up in person for households with no response or without a listed telephone contact. \u00a0\u00a0We may have some new questions on COVID-19 and related health behaviors added in the future early releases.\u00a0 So we\u2019re not quite sure what those questions will be \u2013 only time will tell.<\/p>\n

HOST:<\/strong>\u00a0 In recent years this release has switched from a publication-based format to an interactive web-based data visualization format.\u00a0 But there remains a gold mine of important data topics in this quarterly release.\u00a0 For example, hypertension among adults is now being tracked, which is important particularly now during the pandemic with high blood pressure being a major risk factor for people with COVID-19.<\/p>\n

TAINYA CLARKE:<\/strong>\u00a0\u00a0 The early release data in 2019 and the first half of 2020 showed that about 1\/4 of US adults have been diagnosed with hypertension in the past 12 months, and the prevalence is highest among non-Hispanic Blacks, with more than one in three having hypertension in the past 12 months.<\/p>\n

HOST:<\/strong>\u00a0 The NHIS has tracked cigarette smoking among adults since the 1960s, and has documented along running decline in the percentage of adults who smoke.\u00a0 Cigarette smoking is also one of the topics featured in this week\u2019s new quarterly release showing that an all-time low of 12.2% of American adults were current cigarette smokers in Quarter Two of 2020.\u00a0 And recently, the NHIS has added E-cigarette use to this quarterly release.<\/p>\n

TAINYA CLARKE:<\/strong>\u00a0\u00a0 In 2019 we had approximately 4.4% of adults using E-cigarettes.\u00a0 The percentage is even lower in January to June 2020 at 3.6%.<\/p>\n

HOST:<\/strong>\u00a0 Some of these second quarter estimates from 2020 may indeed reflect the impact of the pandemic on the country.\u00a0 However, many of the survey questions are based on the past 12 months, so any direct connection to the pandemic is inconclusive.\u00a0 This includes the second quarter 2020 finding that a higher percentage of adults are seeking mental health counseling, as well as the fact that a lower percentage of adults visited the emergency Department during this period. Another important measure featured in this quarterly release is flu vaccination.\u00a0 Nearly half of adults reported they received a flu vaccine, according to data from the second quarter of 2020.\u00a0 But Tainya Clarke says some context is needed when interpreting those immunization numbers.<\/p>\n

TAINYA CLARKE:<\/strong>\u00a0\u00a0 I think I want to point out that even though this is almost 50% \u2013 and to some people that may seem like a large percentage \u2013 the target for vaccinating adults against influenza is much higher.\u00a0 It\u2019s closer to 70% for HP 2020 \u2013 that\u2019s a Healthy People 2020 initiative.\u00a0 And although that initiative is targeted at seasonal flu, we really hope to see a larger percentage of the U.S. adult population receiving more flu vaccines going forward.<\/p>\n

HOST:<\/strong>\u00a0 The latest quarterly release of data from the NHIS also includes new data on health insurance coverage in America.\u00a0 During the first half of 2020, over 30 million Americans \u2013 or 9.4% \u2013 were uninsured at the time they were interviewed as part of the survey.\u00a0 This proportion of the population who had no insurance includes over 13% of those ages 18 to 64.\u00a0 In this age group, a little more than one in five had public health insurance and a little more than 2\/3 had private insurance.\u00a0 The poor or near poor in this age group were more likely to be uninsured than those who are not poor. Hispanic adults in this 18 to 64 age group were twice as likely to be uninsured as non-Hispanic black adults and nearly three times as likely as non-Hispanic white or non-Hispanic Asian adults.\u00a0 Among children under age 18, less than 5% were uninsured, and among those who did have insurance over 41% had public coverage and over 56% had private coverage.<\/p>\n

HOST:<\/strong>\u00a0 Our thanks to Tainya Clarke of the National Health Interview Survey for joining us on this edition of \u201cStatcast.\u201d\u00a0 Join us next week for a special segment on data related to the pandemic\u2019s impact on life expectancy.<\/p>\n","protected":false},"excerpt":{"rendered":"
