| Popis: | OBJECTIVES: Serum β-carotene (BC) concentrations are not reflective of dietary BC status as serum concentrations can vary as a result of intake, lifestyle factors, adiposity, and physiological factors related to digestion and absorption. Longitudinal studies have shown a positive relationship between serum carotenoids and dietary BC intake, but the role of body mass index (BMI), as a surrogate for adiposity, in predicting serum BC concentrations is not well understood. The primary objective was to determine the role of BMI in the association between reported dietary BC intakes and serum BC concentrations. METHODS: Relationships between serum BC and reported dietary intake of BC were estimated using data from National Health and Nutrition Examination Surveys (NHANES)/What We Eat in America (WWEIA) survey 2003–2006 for 2580 male and non-pregnant female participants aged 20–85 years in the United States (US). The distributions of reported dietary and serum BC concentrations were skewed, therefore natural log (ln) was used to transform the data. Multivariable linear regression estimated serum BC concentrations based on reported dietary intake of BC adjusted for age, sex, race/ethnicity. Additional models were run by BMI category (normal, overweight, obesity class I, obesity class II, and obesity class III). RESULTS: Mean serum BC concentrations were 14.59 ± 0.1 μg/dL, BMI was 27.80 ± 0.1 kg/m(2), and reported dietary intakes of BC were 828.82 ± 0.06 μg. A moderate association was present between serum BC and reported dietary BC intake, r = 0.30, P |
