AIM:To investigate normoglycemic,prediabetic and diabetic A1c levels in those with prediabetes;and prediabetic and diabetic A1c levels in those with non-prediabetes.METHODS:The National Health and Nutritional Examination Survey(NHANES)2007-2008 and NHANES2009-2010 were utilized to examine and compare trends and differences among five different ethnic groups(Mexican Americans,Other Hispanics,NonHispanic Whites,Non-Hispanic Blacks,Other/Multiracials)with normoglycemic,prediabetic and diabetic A1c levels with self-reported prediabetes and prediabetic and diabetic A1c levels in those with self-reported non-prediabetes.Sample participants of the five ethnic groups were limited to those 20 years of age and older,who had completed the diabetes questionnaire and had A1c measured.Descriptive statistics were computed for all variables.χ2were performed on all five ethnic groups to examine significant differences of normoglycemic,prediabetic and diabetic A1c levels in those with self-reported prediabetes,and prediabetic and diabetic A1c levels in those with self-reported non-prediabetes.RESULTS:This study demonstrates that of the five different ethnic groups from NHANES 2007-2008 to NHANES 2009-2010,Non-Hispanic Whites(6.5%increase)and Non-Hispanic Blacks(0.2%increase)were the only two groups with an increase in the number of self-reported prediabetes.Although the overall percentage of Mexican Americans who self-reported prediabetes had remained the same(5%)from NHANES2007-2008 to NHANES 2009-2010,χ2analysis showed significant differences when examining the different ranges of A1c levels(normoglycemic,prediabetic and diabetic).Among Mexican Americans who self-reported prediabetes,normoglycemic(P=0.0001)and diabetic(P=0.0001)A1c levels from NHANES 2007-2008 to NHANES 2009-2010.For Non-Hispanic Whites who self-reported prediabetes,prediabetic(P=0.0222);and diabetic(P≤0.0001)A1c levels from NHANES2007-2008 to NHANES 2009-2010.For Non-Hispanic Blacks who self-reported prediabetes,there were significant differences(P=0.0001)for all A1c levels(normoglycemic,prediabetic and diabetic A1c levels).For Other/Multi-racials with self-reported prediabetes there was significant differences in those with normoglycemic(P=0.0104)and diabetic(P=0.0067)A1c levels from NHANES 2007-2008 to NHANES 2009-2010.For all combined ethnic groups who self-reported not having prediabetes(non-prediabetes),19.9%of those in NHANES 2007-2008 and 22.4%in the NHANES2009-2010 showed to have prediabetic A1c levels.When separately examining each of the five ethnic groups who self-reported not having prediabetes,all showed an increase in those with prediabetic A1c levels from NHANES 2007-2008 to NHANES 2009-2010.Throughχ2analysis,all five ethnic groups who selfreported not having prediabetes showed significant differences(P<0.0001)in all A1c levels(normoglycemic,prediabetic and diabetic)from NHANES 2007-2008 to NHANES 2009-2010.CONCLUSION:The findings highlight the need of prediabetes awareness and of education in the community as ways to reduce the number of people with prediabetes.
AIM: To investigate normoglycemic, prediabetic and diabetic A1c levels in those with prediabetes; and prediabetic and diabetic A1c levels in those with non-prediabetes. METHODS: The National Health and Nutritional Examination Survey (NHANES) 2007-2008 and NHANES 2009-2010 were utilized to examine and compare trends and differences among five different ethnic groups (Mexican Americans, Other Hispanics, NonHispanic Whites, Non-Hispanic Blacks, Other / Multiracials) with normoglycemic, prediabetic and diabetic A1c levels with self-reported prediabetes and prediabetic and diabetic A1c levels in those with self-reported non-prediabetes.Sample participants of the five ethnic groups were limited to those 20 years of age and older, who had completed the diabetes questionnaire and had A1c measured. Identification statistics were computed for all variables .χ2were performed on all five ethnic groups to examine significant differences of normoglycemic, prediabetic and diabetic A1c levels in those with self-reported pre diabetes, and prediabetic and diabetic A1c levels in those with self-reported non-prediabetes .RESULTS: This study demonstrates that of the five different ethnic groups from NHANES 2007-2008 to NHANES 2009-2010, Non-Hispanic Whites (6.5% increase) and Non-Hispanic Blacks (0.2% increase) were the only two groups with an increase in the number of self-reported prediabetes. Although the overall percentage of Mexican Americans who self-reported prediabetes had remained the same (5%) from NHANES 2007- 2008 to NHANES 2009-2010, χ2analysis showed significant differences when examining the different ranges of A1c levels (normoglycemic, prediabetic and diabetic) .Among Mexican Americans who self-reported prediabetes, normoglycemic (P = 0.0001) and diabetic Levels from NHANES 2007-2008 to NHANES 2009-2010. For Non-Hispanic Whites who self-reported prediabetes, prediabetic (P = 0.0222); and diabetic (P ≦ 0.0001) A1c levels from NHANES 2007-2008 to NHANES 2009-2010.For Non-Hispanic Blacks who self-reported prediabet es, tFor Other / Multi-racials with self-reported prediabetes there was significant differences in those with normoglycemic (P = 0.0104) and diabetic ( P = 0.0067) A1c levels from NHANES 2007-2008 to NHANES 2009-2010. For all combined ethnic groups who self-reported not having prediabetes (non-prediabetes), 19.9% of those in NHANES 2007-2008 and 22.4% in the NHANES 2009 -2010 showed to have prediabetic A1c levels. Both example examining each of the five ethnic groups who self-reported not having prediabetes, all showed an increase in those with prediabetic A1c levels from NHANES 2007-2008 to NHANES 2009-2010. Throughχ2analysis, all five ethnic groups who selfreported not having prediabetes showed significant differences (P <0.0001) in all A1c levels (normoglycemic, prediabetic and diabetic) from NHANES 2007-2008 to NHANES 2009-2010. CONCLUSION: The findings highlight the need of prediabetes awareness and of education in the community as ways to reduce the number of people with prediabetes.
