Objective: Little is known about the rela­tionship between adiposity and telomere length in the United States population. The objective of our research was to examine this relationship in a representative, socio­economically and sex-specific, diverse ra­cial/ethnic population in the United States.Design: Cross-sectional.Methods: Body mass index (BMI), % total body fat (TBF) and waist circumference (WC) with leukocyte telomere length (LTL) were examined according to sex-specific race/ethnicity using separate adjusted mul­tivariate linear regressions on a sample of 4,919 respondents aged 20-84 years from the National Health and Nutrition Examina­tion Survey’s 1999-2002 data.Results: LTL was shortened .41%, .44%, and .16% in African American (AA) women and was associated with increasing BMI, %TBF, and WC, (β:-.0041, 95%CI: -.0070, -.0012; P=.007; β:-.0044, 95% CI: -.0081, -.0007; P=.02; β:-.0016, 95%CI: -.0031, -.0001; P=.04, respectively). LTL was shortened .29% in White women and was associated with increasing %TBF (β:-.0029, 95%CI: -.0048, -.0009; P=.006). There were no associations among AA men, White men or Mexican American men and women.Conclusions: LTL is associated with an obesity phenotype in AA women. Tailored intervention is needed to ameliorate the burden of excess adiposity and subsequent cellular aging. Ethn Dis. 2020;30(3):441-450; doi:10.18865/ed.30.3.441

AbstractObjectiveTo compare infant and toddler anthropometric measurements, feeding practices and mean nutrient intakes by race/ethnicity and income.DesignCross-sectional analysis using general linear modelling. Ten years of survey data (2003–2012) were combined to compare anthropometric measurements, feeding practices and mean nutrient intakes from a nationally representative US sample.SettingThe 2003–2012 National Health and Nutrition Examination Survey (NHANES).SubjectsInfants and toddlers (n 3669) aged 0–24 months.ResultsRates of overweight were higher among Mexican-American infants and toddlers (P=0·002). There were also several differences in feeding practices among groups based on race/ethnicity. Cessation of breast-feeding occurred earlier for non-Hispanic black and Mexican-American v. non-Hispanic white infants (3·6 and 4·2 v. 5·3 months; P<0·0001; P=0·001). Age at first feeding of solids was earlier for white than Mexican-American infants (5·3 v. 5·7 months; P=0·02). There were differences in almost all feeding practices based on income, including the lowest-income infants stopped breast-feeding earlier than the highest-income infants (3·2 v. 5·8 months, P<0·0001). Several differences in mean nutrient intakes by both race/ethnicity and income were also identified.ConclusionsOur study indicates that disparities in overweight, feeding practices and mean nutrient intakes exist among infants and toddlers according to race/ethnicity, which cannot be disentangled from income.

Comorbidity Status

With increasing diabetes prevalence in the US general population, many nutritional supplements are taken as alternative medicine by diabetic patients. However, serial trends or patterns in their dietary supplement use are unknown. Using the nationally representative data from the National Health and Nutrition Examination Survey (NHANES) collected between 1999 and 2014, we evaluated prevalence and trends of use of any supplements, multi-vitamins/multi-minerals (MVMM), individual vitamins, minerals, and non-vitamin, non-mineral supplements. Information on supplement use in the preceding 30 days was collected during the interview over 8 continuous 2-year waves. Analyses were conducted among 6,348 US diabetic adults aged 20 to 85 years (pregnant women excluded) and also stratified by age, race/ethnicity, gender, educational backgrounds, comorbidity status, and comorbidity status. Overall, the prevalence of use of any supplement (52%-59%; P for trend=.09) and that of any mineral (47%-51%; P for trend=.24) seemed stable. Use of MVMM decreased from 36% of reported use in 1999-2000 to 32% in 2013-2014 ( P for trend=.008). Use of any vitamin products increased from 47% to 53% ( P for trend=.04). Use of a few individual supplements including lycopene, vitamin D, and vitamin B12 significantly increased. The trend of supplement use varied by sex and race/ethnicity. In conclusion, among diabetic patients in the United States, use of any dietary supplements or any minerals remained stable, use of MVMM slightly decreased, and use of any vitamins and several individual supplements increased over the past 16 years.

The Relationship

Leukocyte telomere length is shorter in response to chronic disease processes associated with inflammation such as diabetes mellitus and coronary artery disease. Data from the National Health and Nutrition Examination Survey (NHANES) from 1999 to 2002 was used to explore the relationship between leukocyte telomere length and presumed NAFLD, as indicated by elevated serum alanine aminotransferase (ALT) levels, obesity, or abdominal obesity. Logistic regression models were used to evaluate the relationship between telomere length and presumed markers of NAFLD adjusting for possible confounders. There was no relationship between elevated ALT levels, abdominal obesity, or obesity and telomere length in adjusted models in NHANES (OR 1.13, 95% CI 0.48–2.65; OR 1.17, 95% CI 0.52–2.62, resp.). Mexican-American men had shorter telomere length in relation to presumed NAFLD (OR 0.07, 95% CI 0.006–0.79) and using different indicators of NAFLD (OR 0.012, 95% CI 0.0006–0.24). Mexican origin with presumed NAFLD had shorter telomere length than men in other population groups. Longitudinal studies are necessary to evaluate the role of telomere length as a potential predictor to assess pathogenesis of NALFD in Mexicans.
