S. Barua et al., RETINOL AND ALPHA-TOCOPHEROL CONTENT IN BREAST-MILK OF BANGLADESHI MOTHERS UNDER LOW SOCIOECONOMIC-STATUS, International journal of food sciences and nutrition, 48(1), 1997, pp. 13-18
In the present study, concentrations of retinol, alpha-tocopherol and
total solid were determined in the breast milk of Bangladeshi mothers
under low socio-economic status. Mature milk samples were collected fr
om 61 lactating mothers who visited a city maternity centre in Dhaka,
the capital of Bangladesh. Mothers were at varying lactation periods (
1.5-26 months). Retinol and alpha-tocopherol in breast milk were deter
mined by HPLC. Mean (+/- SE) concentrations of breast milk retinol and
alpha-tocopherol were 283.80 mu g l(-1) (+/- 17.4) and 2.04 mg l(-1)
(+/- 0.11) respectively, while that of total solid was 103.30 g l(-1)
(+/- 0.70). Concentration of alpha-tocopherol varied for the variation
of the length of lactation, while the content of retinol and total so
lid did not differ significantly. Alpha-tocopherol concentration beyon
d 6 months post partum was higher as compared to that of earlier perio
ds. Retinol concentration was found to be higher for the comparatively
higher income group. Concentrations of these nutrients were not affec
ted significantly by mother's age. Infant's average daily intake of re
tinol through breast milk was calculated to be 181.02 mu g, while that
of alpha-tocopherol was calculated to be 1.37 mg. Thus breast milk of
Bangladeshi mothers under low socio-economic status cannot cater infa
nts' full requirements for vitamin A (RDA-375RE) and vitamin E (RDA-3-
4 alpha-tocopherol equivalent). Improving mother's diet and timely wea
ning may ameliorate the situation.
