Abstract P220: Sustained Disparity in Ever Having Received a Serum Cholesterol Measurement by Educational Level among US Adults, 1999-2012
Background: A previous study showed that lower educational level was significantly associated with less likelihood of ever having received a serum cholesterol test among US adults during 1999-2002. No study, however, has examined the time trends after 2002.
Objectives: To examine whether disparity by educational level in lifetime receipt of a serum cholesterol test persisted in the US from 1999 through 2012.
Methods: A serial cross-sectional study in a nationally representative sample of 29,662 US adults from the National Health and Nutrition Examination Survey, 1999-2012. We excluded those had coronary heart disease and/or diabetes. The lifetime history of having had a serum test for cholesterol and educational level were asked in the interview. Educational level was grouped as greater than high school (HS), HS, or less than HS. We investigated time trends of lifetime cholesterol measurement by educational level, using a logistic regression model that included interaction terms between survey period and educational level, adjusted for covariates.
Results: In 1999-2000, the proportion of ever having had a serum cholesterol test was significantly lower for participants with less education (greater than HS: 76.2%, HS: 62.0%, less than HS: 51.4%). In 2011-2012, the pattern of lifetime testing by educational level was similar to the initial period (greater than HS: 77.5%, HS: 67.5%, less than HS: 55.4%). Although the uptake of cholesterol testing significantly increased over the survey period among the less-than-HS group, the difference in trends across the three groups was not significant.
Conclusions: The difference by educational level in lifetime serum cholesterol measurement observed in 1999-2002 persisted through 2011-2012. Public health policy should focus on increasing the uptake of serum cholesterol test and early detection of hypercholesterolemia, particularly among people with lower educational level.
