Dietary Fiber Intake and Cardiometabolic Risks among US Adults, NHANES 1999-2010
Section snippets
Study Population
Our study examines data from the 1999-2010 NHANES. The NHANES is a cross-sectional, nationally representative sample of the US noninstitutionalized civilian population.17 The NHANES population was recruited using a multistage, stratified sampling design.17 Our study population included all nonpregnant participants, aged 20 years and older in the 1999 to 2010 NHANES cohorts (n = 30,433). Those with complete data for all covariates including dietary fiber intake, C-reactive protein (CRP), and
Study Population Characteristics
Study population characteristics are listed in Table 1 by mean dietary fiber intake. Reported dietary fiber intake among all nonpregnant adults ranged between 6.3 grams per day (g/d) (10th percentile) and 29.0 g/d (90th percentile). Mean dietary fiber intake was 16.2 g/d (Table 1). In comparison with those who consumed lower amounts of dietary fiber, participants who consumed higher amounts of dietary fiber were more likely to be older (51 years and older), male, Mexican-American, highly
Discussion
Our findings indicate that, among a nationally representative sample of nonpregnant US adults in NHANES 1999-2010, the consumption of dietary fiber was consistently below the recommended total adequate intake levels across survey years. Our study also confirms persistent differences in dietary fiber intake among sex, socioeconomic status, and racial/ethnic subpopulations over time.33 On average, young males consumed almost 20 g less dietary fiber than recommended amounts, with particularly low
