ABSTRACT

OBJECTIVE:

To assess micronutrient intake of black women living in Mangaung, South Africa. SUBJECTS AND

METHODS:

A sample of 500 pre-menopausal black South African women (496 qualified to participate) from two age groups (25-34 and 35-44 years) were selected randomly in Mangaung, the black residential area of Bloemfontein. A validated Quantitative Food Frequency Questionnaire (QFFQ) was used to determine dietary intake of participants. Data were categorized into the two age groups. Median micronutrient intakes were compared to the Recommended Dietary Allowance (RDA) and Adequate Intake (AI). The prevalence of women with intakes < 67% of the RDA was calculated.

RESULTS:

Median calcium and vitamin D intakes were lower than the AI. Of all women, 46.2% to 62.2% consumed < 67% of the RDA for total iron, selenium, folate and vitamin C, and more than 94% consumed < 67% of the RDA for selenium. At least 25% of all women consumed < 67% of the RDA for vitamin A and E. The vitamin B6 intake of older women was inadequate and a fairly large percentage of the total sample consumed < 67% of the RDA.

CONCLUSION:

Generally, micronutrient intakes were adequate in this population. Attention should be given to those micronutrients where median intakes were < 67% of the RDA and those that were not at or above the respective AI in these groups of women.
RESUMEN

OBJETIVO:

Evaluar la ingesta de micronutrientes en mujeres negras de Mangaung, Sudáfrica. SUJETOS Y

MÉTODOS:

Una muestra de 500 mujeres surafricanas negras premenopáusicas (496 clasificaron para participar) de dos grupos etarios (25-34 y 35-44 años) se seleccionó aleatoriamente en Mangaung, el área residencial negra de Bloemfontein. Un cuestionario cuantitativo de frecuencia alimenticia (CCFA) validado, fue usado para determinar la ingesta dietética de las participantes. Los datos fueron clasificados en dos grupos etarios. Se comparó la mediana de las ingestas de micronutrientes con la ración dietética recomendada (RDR), y la ingesta adecuada (IA). Se calculó la prevalencia de mujeres con ingestas < 67% de la RDR.

RESULTADOS:

La mediana de la ingesta de vitamina D y calcio estuvo por debajo de la IA. De todas las mujeres, 46.2% a 62.2% consumieron < 67% de la RDR para el total de hierro, selenio, folato y vitamina C, y más del 94% consumieron < 67% de la RDR para el selenio. Por lo menos 25% de todas las mujeres consumieron < 67% de la RDR para la vitamina A y E. El consumo de vitamina B6 de las mujeres de mayor edad fue inadecuado y un porcentaje bastante grande de la muestra total consumió < 67% de la RDR.

CONCLUSIÓN:

Generalmente, las ingestas de micronutrientes eran adecuadas en esta población. Debe prestarse la atención a los micronutrientes cuyas ingestas medianas fueron < 67% de la RDR y aquellos que no correspondieron o estuvieron por encima del IA respectivo en estos grupos de mujeres.
