Background: In the 1999-2000 National Health and Nutrition Survey 52% of adults reported taking a dietary supplement in the past month. Many adults in the US do not meet the recommended daily intake of nutrients; supplements may help fill in this gap.

Objectives: This analysis examined dietary supplement use among 246 patients attending Public Sector Medicine Clinics from 2005-2007. This population is uninsured and low-income. Eighty-seven percent were women, 75% were over age 40, 56% were not born in the US, and almost half were obese. Fifty-five percent reported consuming ≤1 serving of fruit per day, 50% reported ≤1 serving of vegetables, and 56% ≤1 serving of calcium-containing dairy foods.

Methods: Data were collected via an interviewer-administered questionnaire. Chi-squared analysis was used to determine statistical significance.

Results: Forty-one percent of participants reported using supplements. Multivitamins were the most frequently used supplement (68% of those using supplements). Calcium was the next most frequently reported (19%). Supplement use varied significantly (p<0.05) by (1) age group, (2) self-reported physical activity in the past week such as walking, jogging, or swimming, and (3) in women, receiving a mammogram in the past year. Seeing a health care provider regularly and perceived general health were nearly significant (0.07 and 0.06).

Conclusions: Supplement use in this population was lower than national use and varied by demographic and lifestyle factors. In this population, in which cost may be a barrier to healthier, nutrient rich food options, supplement use may be a means of increasing nutrient intake.
