Total and High-density Lipoprotein Cholesterol in Adults: United States, 2015–2018

April 22, 2020

Questions for Margaret Carroll, Health Statistician and Lead Author of “Total and High-density Lipoprotein Cholesterol in Adults: United States, 2015–2018.”

Q: How has the prevalence of high total cholesterol among US adults changed since 1999-2000 data and and low high-density lipoprotein cholesterol (HDL-C) since 2007-2008?

MC: There has been a declining trend in the prevalence of high total cholesterol since 1999-2000 and a declining trend in the prevalence of low HDL-C since 2007-2008.


Q: Can you summarize how the data varied by sex, age groups and race?

MC: The prevalence of high total cholesterol:

  • Higher in adults aged 40-59 than in adults aged 20-39 and those aged 60 and over
  • Not significantly different between men and women aged 20 and older
  • Not significantly different among non-Hispanic white, non-Hispanic black, non-Hispanic Asians and Hispanics

The prevalence of low HDL-C:

  • Higher in men than in women overall, within each age group and within each race and Hispanic origin group.
  • lower among NH black adults than in non-Hispanic white adults, non-Hispanic Asian adults and Hispanic adults over all and in men.
  • Higher among Hispanic adults than among non-Hispanic white, non-Hispanic black and non-Hispanic Asian adults overall, among men and among women.

Q: Was there a specific finding in the data that surprised you from this report?

MC: Although we weren’t surprised because the results have been seen in the past, men continue to have a much higher prevalence of low HDL-C compared to women.


Q: How did you obtain this data for this report?

MC: Results presented in this report are based on data from the National Health and Nutrition Examination Survey (NHANES), a nationally representative, cross sectional, probability survey representative of the United States non-institutionalized population.  Beginning in 1999 NHANES became a continuous survey and data have been released in 2-year cycles.  Data from 2015-2016 and 2017-2018 were used to test differences in the prevalence of high total and low HDL-C cholesterol between subgroups. Trends in the prevalence of high total cholesterol are based on data from ten 2-year cycles from 1999-2000 through 2017-2018. Trends in the prevalence of low HDL-C are based on six 2-year cycles from 2007-2008 through 2017-2018


Q: What is the take home message for this report?

MC: Over 1 in ten (11%) adults have high total cholesterol and over 17% have low HDL-C. The prevalence of high total cholesterol has declined since 1999-2000; the prevalence of low HDL-C has declined since 2007-2008.


Contribution of Whole Grains to Total Grains Intake Among Adults Aged 20 and Over: United States, 2013–2016

July 9, 2019

New NCHS report provides estimates of the percentage of total grains intake consumed from whole grains sources, for U.S. adults aged 20 and over who reported consumption of grains (98.6%) on a given day during 2013–2016.

Findings:

  • During 2013–2016, whole grains accounted for 15.8% of total grains intake among adults on a given day. This percentage increased with age from 12.9% among adults aged 20–39 to 19.7% for adults 60 and over.
  • Overall, the contribution of whole grains to total grains intake was lower among men (14.8%) than women (16.7%).
  • The contribution of whole grains to total grains intake was lowest among Hispanic adults (11.1%) compared with non-Hispanic white (16.5%), non-Hispanic black (13.7%), and non-Hispanic Asian (18.3%) adults.
  • The contribution of whole grains to total grains intake on a given day increased with increasing family income.
  • From 2005–2006 to 2015–2016, the contribution of whole grains to total grains intake increased for adults overall, and for men and women.

Adults’ daily protein intake much more than recommended

March 3, 2010

March is National Nutrition month, making it a great time to look at where America stands in its nutrition and diet.  One important nutrient is protein, which is essential to the human body because it is part of every cell, issue, and organ, allowing them to grow and repair. Proteins can be found in a variety of foods that we eat on a regular basis and the table below displays the Centers for Disease Control and Prevention’s recommended daily protein intake.

However, according to the 2005-2006 National Health and Nutrition Examination Survey (NHANES), both men and women ages 20 and over were taking in much more than the recommended amount of protein. The recommended daily amount of protein is 46 grams for women and 56 grams for men. The NHANES results showed that men were taking in 101.9 grams and women were taking in 70.1 grams. Protein intake contributes to calorie intake: therefore, if you eat more protein than is needed, your overall calorie intake could be greater and potentially lead to weight gain.
