Infant nutritional status depends on the mother’s status

Starting in Pregnancy? Or Before?

Nutrient status of the mother Pre-pregnancy diet Pre-pregnancy diet Pre-pregnancy nutritional status Pre-pregnancy nutritional status Pre-pregnancy work load or activity level Pre-pregnancy work load or activity level Spacing between pregnancies Spacing between pregnancies

Measuring Adult Nutritional Status Body Mass Index BMI = weight (kg) / height (m) kg / (1.6 m x 1.6 m) = 24

Effects of Maternal Nutrition Ability to nourish in-utero starting at conception Ability to nourish in-utero starting at conception Ability to provide quality breastfeeding without depleting her own nutrient stores Ability to provide quality breastfeeding without depleting her own nutrient stores Maintenance of her quality of life, productivity and capacity to care for child Maintenance of her quality of life, productivity and capacity to care for child

Energy Needs during Lactation Increase by up to 500 kilocalories per day Increase by up to 500 kilocalories per day Fat stored during pregnancy can be used to satisfy this energy requirement Fat stored during pregnancy can be used to satisfy this energy requirement Increased energy intake does not result in increased milk production in adequately nourished women Increased energy intake does not result in increased milk production in adequately nourished women Sufficient amount of milk can be produced by women with low energy intake Sufficient amount of milk can be produced by women with low energy intake

Why so much energy for lactation? Human milk is about 70 kcal/100 ml Human milk is about 70 kcal/100 ml Maternal energy is converted with about 80% efficiency to milk energy Maternal energy is converted with about 80% efficiency to milk energy ~85 kcal of maternal energy needed to produce 100 ml of breast milk ~85 kcal of maternal energy needed to produce 100 ml of breast milk An average milk secretion of 750 ml per day, requires 640 kcal/day An average milk secretion of 750 ml per day, requires 640 kcal/day Some of this can come from stored fat Some of this can come from stored fat

Nutrient Quality of Breast Milk Energy, protein, and some mineral content is not affected by maternal dietary intake or stores Energy, protein, and some mineral content is not affected by maternal dietary intake or stores Vitamin C, thiamine, riboflavin, B6, B12, Vitamin A, iodine and selenium are dependent on maternal intake or stores Vitamin C, thiamine, riboflavin, B6, B12, Vitamin A, iodine and selenium are dependent on maternal intake or stores Maternal intake has minimal effect on content of zinc, iron, folate, Vitamin D, calcium and copper content of breast milk Maternal intake has minimal effect on content of zinc, iron, folate, Vitamin D, calcium and copper content of breast milk

Protein About 925 g of new protein are synthesized and deposited in mother and fetus About 925 g of new protein are synthesized and deposited in mother and fetus Average breast milk production per day ml with protein content of 1.25 g/100 ml Average breast milk production per day ml with protein content of 1.25 g/100 ml Adequate energy intake from carbohydrates is essential to assure new protein synthesis Adequate energy intake from carbohydrates is essential to assure new protein synthesis

Iron-deficiency anemia 50% of anemia is from iron deficiency 50% of anemia is from iron deficiency Absorption may be as important as low dietary intake Absorption may be as important as low dietary intake Inhibitors Inhibitors Heme vs. non-heme Heme vs. non-heme Other major causes of anemia: Other major causes of anemia: Malaria Malaria Helminthes Helminthes

Efficacy of Iron Supplementation World Bank review found that distribution was the limiting factor not utilization World Bank review found that distribution was the limiting factor not utilization Counseling on purpose is as important as counseling on controlling side effects Counseling on purpose is as important as counseling on controlling side effects Some concern that iron inhibits zinc and copper absorption Some concern that iron inhibits zinc and copper absorption

Actions to Prevent Anemia Promote intake of iron-rich foods, especially animal products and fortified foods Promote intake of iron-rich foods, especially animal products and fortified foods Provide iron supplementation to pregnant women Provide iron supplementation to pregnant women Continue supplementation for 3 months post-partum in areas with anemia prevalence >40 percent Continue supplementation for 3 months post-partum in areas with anemia prevalence >40 percent De-worming of pregnant women after first trimester, and lactating women, according to WHO protocol De-worming of pregnant women after first trimester, and lactating women, according to WHO protocol Prevent and control malaria Prevent and control malaria
