Docosahexaenoic acid level of the breast milk of some Filipino women

This study was conducted to determine the docosahexaenoic acid (DHA) level of the breast milk of 100 Filipino women as affected by diet. The subject distribution was patterned after the 1997 Family and Income Expenditure Survey of the National Statistics Office regarding the total number of families, and the total and average family income and expenditures by income class in an urban area. The subjects were asked to complete a 3-day food record and food frequency questionnaire to ascertain the nutrient content of their food intake and approximate eating habits. Hind milk was drawn manually by means of a fabricated glass breast pump and collected in polypropylene vials. The milk samples were stored in a freezer maintained at -25+/-2degreesC until they were transported to the University of Montreal for fatty acid composition. The milk was methylated using the Lepage and Roy method. The obtained fatty acid methyl esters were analyzed by gas chromatography. Results showed that the milk samples contain an average of 188.34 mug DHA/ml milk, while %DHA of the samples is 0.65%. Regression analysis revealed that mean protein intake of the subjects was a determinant of the DHA level in the milk samples.
