Abstract
Magnesium plays a crucial role in hundreds of bodily processes relevant to aging,
but consumption of dietary magnesium intake has been shown to be inadequate in a large
proportion of older adults. Identifying groups at risk of low magnesium intake is important
for informing targeted advice. Using data from the National Health and Nutrition Examination
Survey (NHANES) 2005–2016, we examined the association between ethnicity (Caucasian/African
American/Hispanic/other) and magnesium intake in a large representative sample of U.S. older
adults (≥65 y, n = 5682, mean (SD) 72.9 (0.10) y). Analyses adjusted for total energy intake and a
range of relevant covariates. Overall, 83.3% of participants were not meeting the recommended
level of dietary magnesium intake, ranging from 78.1% of other ethnic groups to 90.6% of African
Americans. In the fully adjusted model, magnesium intake was lower among African American older
adults (−13.0 mg/d, 95% CI: −18.8 to −7.2), and higher among Hispanics (14.0 mg/d, 95% CI: 7.5 to
20.5) and those from other ethnic groups (17.2, 95% CI: 3.8 to 30.5) compared with Caucasian older
adults. These results highlight the need for targeted interventions to increase magnesium intake in
U.S. older adults, with a focus on African Americans, in order to reduce the burden of morbidity and
ethnic inequalities in health in later life.
