Assessment of dietary intake in an inner-city African American population and development of a quantitative food frequency questionnaire to highlight foods and nutrients for a nutritional invention.

PRIMARY OBJECTIVE To characterize the diets of low-income inner-city African Americans to develop a population-specific quantitative food frequency questionnaire (QFFQ) that will be used to highlight foods and nutrients for a nutritional intervention program aimed at reducing the risk of chronic disease and to evaluate the program. METHODS AND PROCEDURES A cross-sectional survey conducted in inner-city Baltimore, Maryland, USA. Twenty-four-hour dietary recalls were collected in 91 low-income African Americans aged between 18 and 74 years. MAIN OUTCOMES AND RESULTS The average daily energy intake was approximately 2,165 kcal for women and 2,509 kcal for men. The percentages of energy from fat were approximately 34% and 33% for women and men, respectively. Sodas were the main contributor to energy and sugar intake. A 113-item QFFQ was developed. CONCLUSIONS The results highlighted specific foods and nutrients that would be targeted in the nutritional intervention. The QFFQ developed is culturally appropriate and specific for low-income African Americans in inner-city Baltimore.
