Little is known about the iron status of Hispanic groups in the United States. Data from the Hispanic Health and Nutrition Examination Survey were used to estimate the prevalence of impaired Fe status for persons aged 5-74 y from three Hispanic groups: Mexican Americans (MAs), Cubans, and Puerto Ricans; prevalences were also calculated for non- Hispanic whites (NHWs) and non-Hispanic blacks (NHBs) using data from the second National Health and Nutrition Examination survey. A three- variable model called the MCV model was used to assess impaired Fe status. Prevalences based on the MCV model did not differ between Hispanic groups. Differences between Hispanics and non-Hispanics occurred only among 20-44-y-old females, where MAs had a higher prevalence than NHWs or NHBs. With this exception, these Hispanic groups do not appear to be at greater risk of impaired Fe status than non-Hispanics.
