Formulation and evaluation of supplementary foods for Thai pregnant women.
To improve maternal nutritional status and to ameliorate protein-energy malnutrition in pregnant women and infants, supplementary foods for rural pregnant women were formulated and evaluated. Six formulas with protein and energy contents of 16-22 g and 350-500 kcal/100 g food, respectively, were developed from locally available raw materials. A field evaluation of formulas I and V was conducted at the regional MCH Center at Rajchaburi, about 120 km from Bangkok. Formulas providing 13 g protein and 350 kcal per day were given to two groups of mothers in the first or second pregnancy, starting at 28 +/- 2 wk of gestation. A third group, unsupplemented, served as controls. Maternal weight gain and left mid-arm circumference were measured every 2 wk. Birth weight, length, head and chest circumferences of newborns, and placental weight were significantly higher in both supplemented groups. These findings suggest that among undernourished mothers, supplementation of as little as 13 g protein and 350 kcal daily during the last trimester can significantly improve maternal weight gain and birth weight of newborns.
