CHARACTERISTICS OF NHANES CHILDREN AND ADULTS WHO CONSUMED GREATER THAN OR EQUAL TO 50% OF THEIR CALORIES/DAY FROM SUGAR AND THOSE WHO DO NOT Data from the National Health and Nutrition Examination Survey (NHANES) Cycles 2005-2006, 2007-2008, 2009-2010, & 2011-2012 Kelly Nemec NHANES Research Project NTR 555 Nutrition in Epidemiology December 8, 2015
Background and Rationale Dietary sugar intake among children and adults has been of concern over the past decade Over the past few years, US children have been consuming about 16% of their calories from sugar, while adults have been consuming about 13% of their calories from sugar 1,2 Researchers have found that those who smoke every day consume more sugar and those who have higher education consume less sugar 3,4 Previous research shows an association among sugar intake and food security status 5
Research Question What are the characteristics of NHANES US children and adults who consume 50% or more of their calories/day from sugar and who consume less than 50% of their calories/day from sugar?
Objectives Determine the characteristics of children and adults who consumed 50% of their calories from sugar and those who consumed <50% of their calories from sugar. Determine the association among adults who consumed 50% of their calories from sugar and those who consumed <50% of their calories from sugar and education level. Determine the association among adults who consumed 50% of their calories from sugar and those who consumed <50% of their calories from sugar and smoking status. Determine the association among adults and children who consumed 50% of their calories from sugar and those who consumed <50% of their calories from sugar and race/ethnicity. Determine the association among adults and children who consumed 50% of their calories from sugar and those who consumed <50% of their calories from sugar and child and adult food security category. Determine the association among adults who consumed 50% of their calories from sugar and those who consumed <50% of their calories from sugar and marital status.

Discussion 1.46% of children consumed 50% of their calories from sugar, while 98.54% of children consumed <50% of their calories from sugar 2.36% of adults consumed 50% of their calories from sugar, while 98.44% of adults consumed <50% of their calories from sugar There were statistically significant associations among sugar intake and marital status, smoking status, race/ ethnicity, and education level However, not clinically significant given low effect size Associations among sugar intake and smoking status, race/ethnicity, and education level is consistent with most of past research 1-4 There was no association among sugar intake and food security in both children and adults Research suggests that low food security is associated with increased sugar intake 5
Conclusion Non-Hispanic white children and adults and current every day smokers consumed a larger percent of their calories from sugar Those with higher education consumed less calories from sugar Further research needed to examine a broader range of individuals with more variety of demographic variables
