  • 4th Report - The World Nutrition Situation: Nutrition throughout the Life Cycle (IFPRI - UNSSCN, 2000, 136 p.)
  • Slide 4: Maternal Malnutrition: A Life-Cycle Issue (one) Women are vulnerable to malnutrition throughout the life cycle for both biological and social reasons. Infancy and early childhood (0–24 months) . Most young girls living in poor environments are suboptimally breastfed in infancy and early childhood, receive infrequent and poor complementary foods (both in quantity and/or quality), and suffer frequent infections. Such nutritional neglect during the first two years of life has immediate and long-term negative consequences on women’s survival, growth, development, and productivity. Childhood (two to nine years) . At two years of age, many of the girls who survive under such nutritional stress are stunted with little chance of recovery. Moreover, in some parts of the world, girls are discriminated against in access to food, health care, and education throughout childhood .
  • Slide 5: Maternal Malnutrition: A Life-Cycle Issue (two) Adolescence (10–19 years). During adolescence, girls experience rapid physical growth and sexual maturation which significantly increases their needs for macronutrients and micronutrients (especially iron). Adolescent girls’ growth spurt occurs before menarche (first menstruation). Adolescent girls continue to grow in height long after menarche. Linear growth, particularly of the long bones, is not complete until the age of 18, and peak bone mass is not achieved until the age of 25. A malnourished adolescent girl whose menarche has been delayed may achieve full height as late as 23 years and will, therefore, be capable of conceiving before her body size is fully developed. Moreover, the development of the birth canal is slower than that of height and does not reach mature size until about two to three years after the growth in height has ceased. Pregnancy puts adolescent women at increased risk of malnutrition (diverting nutrients from the mother to the fetus), pregnancy complications, and poor pregnancy outcomes (including death). Early pregnancy contributes to the cycle of maternal malnutrition in two ways: Indirectly, through the premature cessation of the mother’s growth. Directly, through the increased risk of delivering a low birth weight baby. Pregnancy and lactation. In most developing countries, women spend a large proportion of their reproductive years pregnant, lactating or pregnant and lactating. McGuire and Popkin (1990) estimate that on average, African and Asian women between the ages of 15 and 45 are pregnant or lactating 30–48 percent of their time. The nutritional demands during pregnancy and lactation are multiple to support fetal growth and breastmilk production. These added nutritional requirements specific to pregnancy and lactation manifest themselves both at the macronutrient and the micronutrient level. More calories are needed to achieve adequate pregnancy weight gain and build stores for lactation. More iron is needed because of the growth of the fetus and placenta and the expansion of plasma volume. More vitamin A may be needed to ensure adequate vitamin A concentration in breastmilk. Closely spaced reproductive cycles, negative energy balance, and micronutrient deficiencies can lead to a condition known as “maternal depletion syndrome”. Nutritional stress is greatest when an adolescent woman is pregnant and lactating.
  • Slide 6: Maternal Malnutrition: a Life-Cycle Issue (three) Throughout life. Most women living in developing countries experience various biological and social stresses that increase the risk of malnutrition throughout life. These include: Food insecurity Inadequate diets Recurrent infections Frequent parasites Poor health care Heavy work burdens Gender inequities
  • Fetal growth has become fashionable because of the hypothesis of the fetal origins for adult disease which has been advocated by David Barker and his team. These two books summarize much of evidence which I will discuss at the end of the talk.
  • Let begin by addressing the definition of growth
  • Let begin by addressing the definition of growth
  • This baby has a growth disorder. It was born at term but starved in utero. It lacks sub-cutaneous tissue as can be seen by the prominent iliac wing and a thin leg (Pat insert arrows). So there is no question that intra-uterine starvation occurred.
  • More than a decade ago, we have proposed that preterm labor is a syndrome characterized by the presence of uterine contractions, cervical ripening and membrane/decidual activation caused by (click) infection/inflammation, which is the most common cause studied in the context of preterm labor and delivery. Our group and others have clearly demonstrated the importance of infection, the prevalence and the clinical significance of infection in preterm birth. The other potential causes are … (click) X 5
  • In contrast, intrauterine growth retardation is the failure to achieve an individual optimal growth potential Such a failure may occur even in the infants is above the 10 th percentile

  • Some salts, bread and seafood have been supplemented with iodine. Iodine may be found in other locally available foods. The US recommended daily allowance is 150  g/day for adults, 175  g/day for pregnant women and 200  g/day for lactating women.
  • Therefore, both nutrients play important roles in immune function and the modulation of host resistance to infectious agents, reducing the risk, severity, and duration of infectious diseases
  • Classifications of anemia were taken from the World Health Organization (WHO). December 2000. Essential Care Practice Guide: Pregnancy, Childbirth and Newborn Care . Draft. Severe anemia is associated with a significantly increased risk of complications in pregnancy, specifically low birth weight newborns, premature birth, perinatal mortality, and increased maternal mortality and morbidity. This increase is due to low oxygen-carrying capacity for both fetus and mother.
  • Foods abundant in iron include: red meat (especially liver), poultry, fish, whole grains, dark green leafy vegetables, shellfish and dried fruit. Absorption is improved if taken with foods containing vitamin C. Adult females should get 30 mg/day, especially if they are pregnant.
  • Slide 40: Improving Maternal Weight Increases in weight can be achieved within a woman’s reproductive life by: Increasing caloric intake and/or by Reducing energy expenditure and/or by Reducing caloric depletion (delaying the first pregnancy and increasing birth intervals)

  • Fetal Origins of Adult Disease
  • Maternal nutrition A healthy, balanced diet that contains adequate amounts of nutrients is essential for the development of a baby During pregnancy and after delivery, a mother’s body goes through many physiological changes, including a need for increased nutrients and energy
  • The nutritional status of pregnant women in India 60 plus years,India is still poor, pregnant and powerless
  • Current scenario in India Pregnant women with the calorie consumption of less than 50% of the recommended had a lower serum zinc level compared to the women who had a higher calorie intake Asia Pac J Clin Nutr 2008;17 (2):276-279 Results on dietary intake showed that 18%, 34%, 85% and 57% of the pregnant women were consuming less than 50% of calories, proteins, iron and b-carotene, respectively as compared to their RDA

  • Normal Placental Development Uterine spiral artery remodeling takes place by the invasion of trophoblast cells into the uterine lining. These trophoblasts enter the arterial walls and replace parts of the vascular endothelium so that smooth muscle is lost and the artery dilates. Poor placentation and preeclampsia
  • Sadler TW Lagman’s Medical Embryology 1990 Umbilical Chorionic vessels Chorionic plate Amnion vessels Normal Placental Development Placental Spiral septum Uteroplacental Basal artery veins plateFrom 9-12 weeks gestation the uterine spiral arteries are transformed from thick-walled, muscular vessels, to more flaccid tubes to accommodate a 10-foldincrease in uterine blood flow to support the pregnancy.
  • An immune response facilitates normal placental development: In the uterine decidua, maternal lymphocytes and macrophages assist the trophoblasts to invade into the uterine myometrium and the spiral arteries.

  • Hyperhomocystenemia as a risk factor____ Women who develop severe preeclampsia have higher plasma homocysteine levels in early pregnancy than women who remain normotensive throughout pregnancy. [threefold risk ] --- Cotter AM, Molloy AMet al, Am J Obstet Gynecol. 2002 May;186(5):1107; Am J Obstet Gynecol. 2001 Oct;185(4):781-5.
  • Hyperhomocystenemia as a risk factor____ Pregnant women with hyperhomocysteinemia have a 7.7-fold risk for preeclampsia – López-Quesada E, Vilaseca MA, Lailla JM. Eur J Obstet Gynecol Reprod Biol. 2003 May 1;108(1):45-9.
  • Hyperhomocystenemia as a risk factor____ Hyperhomocysteinemia is associated with pre- eclampsia as well as eclampsia, but in eclampsia the severity of homocysteine elevation is more compared to that in pre-eclampsia. ___ Hoque MM, Bulbul T, Mahal M, Islam NA, Bangladesh Med Res Counc Bull. 2008 Apr;34(1):16-20.
  • Hyperhomocystenemia as a risk factor____ Both maternal and umbilical cord plasma homocysteine concentrations were elevated in pregnancies complicated by pre-eclampsia compared to normotensive controls. Aust N Z J Obstet Gynaecol. 2008 Jun;48(3):261-5.

  • BRAIN NUTRIENTS Presentation Title Company Confidential Date © 200X Abbott
  • Brain NutrientsDHA Docosahexaenoic acid (DHA, 22:6n23)- limited capacity for synthesis inside body, hence conditionally required in diet Major omega-3 fatty acid needed to build fetal brain Critical period during which dietary DHA may be needed to optimize brain development extends from mid-pregnancy into the first year of life DHA accumulation in fetal brain is most rapid during the last intrauterine trimester & first year of life Am J Clin Nutr 2009;89(suppl):685S–7S
  • Omega fatty acids Essential Dietary source: sea food India standard of 2 servings/week: Inadequate critical for fetal neurodevelopment and may be important for the timing of gestation and birth weight as well – DHA fetal development of brain & retina during 3 rd trimester and up to 18 months of life. – EPA play role in DHA transplacental transport & intracellular absorption. Rev Obstet Gynecol. 2008;1(4):162-169
  • Omega 3 – fatty acids Fatty acids of the omega-3 series (n-3 fatty acids) present in fish are well established dietary components affecting plasma lipids and the major cardiovascular disorders, such as arrhythmias.
  • Role of DHA DHA is an omega-3-fatty acid and is derived from alpha-linolenic acid. It accounts for about 40% of poly- unsaturated fatty acids in the brain and 60% in the retina.
  • Benefits of DHA Various studies have shown that a higher maternal DHA status/cord blood DHA was associated with: Longer gestation Higher visual acuity Better cognitive development in infants Studies have also shown that women with lower omega-3- fatty acids were 6 times more likely to get depressed during the antenatal period. A daily intake of DHA in pregnant and lactating women is recommended to be 200 mg
  • Benefits of DHA Various studies have shown that a higher maternal DHA status/cord blood DHA was associated with: Longer gestation Higher visual acuity Better cognitive development in infants Studies have also shown that women with lower omega-3- fatty acids were 6 times more likely to get depressed during the antenatal period. A daily intake of DHA in pregnant and lactating women is recommended to be 200 mg
  • Folate Folate deficiency has been reported in parts of India, West Africa, and Burma It is due to inadequate dietary intakes, cooking habits that exacerbate losses, food taboos Deficiency is associated with megaloblastic anemia, low birth weight, and potential fetal anomaly Murphy et al have reported that mothers with Hyperhomocysteinemia at 8 wk of pregnancy had nearly four times the odds of giving birth to LBW neonate Murphy MM. Clin Chem 2004; 50 : 1406-12.
  • Treatment Dietary modification Folate supplementation Methylcobalamin supplementation particulary for indian population due to high prevalance of vegeterian diet Supplementation of pyridoxine[B6] Anticagulation if history of thrombosis
  • FOLIC ACIDImportant cofactor in the Remethylation of Homocysteine  Adequate intake minimizes DNA uracil and plasma Hcy accumulation, resulting in reduced risk of chromosome breaks.  Folic acid-vitamin B supplementation significantly reduce tHcy levels (Bostom et al, 2002).  Low conc associated with risk of preterm delivery, Low birth weight infants and FGR AJCN. 2000; 71: 1295S-1303S, Am J Obstet Gynecol. 2004 Dec;191(6):1851-7.
  • L methyl Folate ..(Natures Folate) L-methylfolate is the primary biologically active form of folate1 and the primary form of folate in circulation. Folic acid, the synthetic form of folate, must undergo enzymatic reduction by methylenetetrahydrofolate reductase (MTHFR) to become biologically active
  • The Active Folate L-methylfolate is a substantially pure source of L-methylfolate containing not more than 1% D-methylfolate. D-methylfolate is not metabolized by the body and inhibits regulatory enzymes related to folate and homocysteine metabolism and reduces the bioavailability of L-methylfolate.
  • Brain NutrientsFolic acid Neural Tube Defects (NTDs) are common (the most common malformations of the central nervous system and probably second only to cardiac defects) among major congenital anomalies Maternal folic acid supplementation prevents a substantial proportion of NTDs American College of Obstetricians and Gynecologists & American Academy of Pediatrics, Food and Nutrition Board of the Institute of Medicine also recommended that all women capable of becoming pregnant should consume 0.4 mg of folate daily from supplements or fortified foods or a combination of the 2 in addition to consuming folate from a varied diet Am J Clin Nutr 2007;85(suppl):285S– 8S
  • Brain NutrientsFolic acid Plays important role in nucleic acid synthesis Marginal folate intake during gestation can impair cellular growth & replication in the fetus or placenta Sustained intake after complete closure of the neural tube to decrease the risk of other poor pregnancy outcomes During pregnancy, low concentrations of dietary and circulating folate are associated with increased risks of preterm delivery, infant low birth weight, and fetal growth retardation Am J Clin Nutr 2000;71(suppl):1295S–303S
  • Folic acid In Females : • Folic acid plays imp role in oocyte quality and maturation, implantation, fetal growth and organ development In Male : • Folic Acid plays an important role in DNA synthesis and in spermatogenesis • Folic acid proves to increase sperm count, enhance sperm motility and reduces immature cells in semen
  • VITAMIN B12A cofactor, Methionine Synthetase (MS) in methylation Enzyme, catalyses the transfer of CH3 group from MethylTetrahydrofolate Homocysteine In Vit. B12 def, folate is trapped as unusable MTHF, causing functional folate deficiency. Thus plays a key role in the remethylation of Homocysteine to Methionine.
  • VITAMIN B6 A cofactor, Pyridoxal Phosphate in methylation Reduces the level of homocysteine by the process of transulphuration to cysteine & hence related pregnancy complications are reduced. Vitamin B6 levels of mothers at the onset of pregnancy have a positive correlation with birth weight of newborns (Int J Vitam Nutr Res. 1978;48(4):341-7) Needed for CNS formation of fetus
  • Brain NutrientsIodine• Providing adequate iodine in mid-to- late pregnancy improves infant cognitive development, there are greater benefits when iodine is given before or early in pregnancy Am J Clin Nutr 2009;89(suppl):685S–7S
  • Brain NutrientsIodine WHO increased their recommended iodine intake during pregnancy from 200 to 250 mcg/d & suggested a median urinary iodine (UI) concentration of 150– 249 lg/L indicates adequate iodine intake in pregnant women Cross-sectional studies - reported impaired intellectual function & motor skills in children from iodine-deficient areas An adequate iodine supply should continue after child birth Iodine requirement of women who is fully breastfeeding her infant is even higher than that during pregnancy
  • Iodine Supplementation  Iodine deficiency is a preventable cause of mental impairment  Supplementation may be effective at preconception up to mid-pregnancy period  Form of iodine supplementation (iodinating food or oral/injectable iodine) depend on: – Severity of iodine deficiency – Cost – Availability of different preparation Enkin et al 2000; Mahomed and Gülmezoglu 2000.
  • Brain NutrientsFolate, Choline Folate is an essential vitamin, whereas choline is class of nutrients for which there is limited capacity for synthesis inside body, & therefore conditionally required in the diet Choline is required for membrane synthesis, methylation reactions, and for neurotransmitter synthesis Maternal dietary deficiency of either choline or folic acid diminishes new nerve formation (neurogenesis) and increases neural cell death in the fetal brain Am J Clin Nutr 2009;89(suppl):685S–7S
  • Brain NutrientsCholine Choline status during pregnancy influences brain development in fetus Transport of choline from mother to fetus depletes maternal plasma choline Demand for choline is so high that stores are depleted Hence supply of choline is critical during pregnancy Because milk contains a great deal of choline, lactation further increases maternal demand for choline, resulting in further depletion of tissue stores
  • Brain NutrientsCholine During pregnancy and lactation - maternal reserves depleted At the same time, the availability of choline for normal development of brain is critical Lack of choline in a mother’s diet during pregnancy and lactation may have life-long adverse effects on their child The Institute of Medicine (IOM) of the National Academy of Sciences set an adequate intake (AI) level for choline of 550 mg/day for men and 425 mg/day for women Journal of the American College of Nutrition, 2004; 23 (6), 621S–626S

  • Growth NutrientsCalcium Developing fetal skeleton accumulates about 30 g of calcium by term, about 80% of it during the third trimester Women lose 300 to 400mg of calcium daily through breast milk, this calcium demand is met by a 5–10% loss of skeletal mineral content during 6 months of exclusive lactation Women nursing twins, Ca losses may be as great as 1000 mg or more Limited maternal intake of Ca & other minerals may adversely affect fetal skeletal development, or perhaps lead to severe losses of maternal bone mineral content during pregnancy Low calcium intake might adversely affect fetal development, and is important to recommend calcium supplementation during pregnancy Journal of Mammary Gland Biology and Neoplasia,2005,10(2)
  • Calcium Recommend increase in calcium intake through diet in women at risk of hypertension or low calcium areas Reduction of incidence of PIH Calcium decreases risk pre-eclampsia, low birth weight, and chronic hypertension in children Maintain bone strengthBucher et al 1996; Kulier et al 1998; Lopez-Jaramillo et al 1997.
  • Growth Nutrients Vitamin D Maternal vit D deficiency during pregnancy was reported about 18% in UK, 25% in the UAE, 80% in Iran, 42% in northern India, 61% in New Zealand and 60–84% of pregnant non-Western women in the Netherlands, have been shown serum concentrations of 25(OH)D [25 Hydroxy vitamin D3] <25 nmol/l Studies show that infants are entering the world with a vitamin D deficit that begins in utero (within womb of mother) Concern is based on the strong relationship between maternal and fetal (cord blood) circulating 25(OH)D levels, studies from many countries, have demonstrated a high prevalence of vitamin D deficiency in mother-infant pairs at birth Significance of maternal deficiency during pregnancy - fetus developing in a state of hypovitaminosis D, which likely has significant effects on fetal and childhood bone development Am J Clin Nutr 2009;89(suppl):685S–7S
  • Growth NutrientsVitamin D Risk of osteoporotic fracture in adulthood could be determined partly by environmental factors during fetal life and early infancy In a longitudinal study, 198 children born were followed up for 9 years of age. Body builds, nutrition, and vit D status of mothers recorded during pregnancy Children were followed up at age 9 yrs to relate these maternal characteristics to their body size and bone mass Reduced concentration of 25(OH)-vitamin D in mothers during late pregnancy was associated with reduced whole-body and lumbar-spine bone-mineral content in children at age 9 years Reduced concentration of umbilical-venous calcium also predicted reduced childhood bone mass Vitamin D supplementation of pregnant women, could lead to reductions in the risk of osteoporotic fracture in their offspring Lancet 2006; 367: 36–43

Minerva Ginecol. 1997 Dec;49(12):577-81
  • acceleration of fetal growth inpregnancy complicated by IUGR L-arginine 3 gm/day orally accelerated fetal growth. with mean value of 2526 g Neonates delivered in L-arginine group revealed higher Apgar score, better umbilical cord acid-base status. Lower incidence of RDS and admission to NICU.
  • Oligohydramnios Means less amniotic fluidAmniotic fluid volume predictive of IUGR Second trimester amniotic fluid levels of NO in women who subsequently developed IUGR have been shown to be lower than in controls. NO could play an important role in the prevention and treatment of IUGR as it can improve uteroplacental circulation increasing fetal blood supply
  • NO in PIH and Pre-eclampsia Preeclampsia is associated with decreased endothelial nitric oxide synthase expression, which increases cell permeability (Wang, 2004) Nitric oxide maintains the normal low-pressure vasodilated state characteristic of fetoplacental perfusion (Myatt, 1992)
  • L-arginine in Pregnancy induced HT Rytlewski et al. • L-arginine orally in dose 6 g/day in gestation complicated by pregnancy-induced hypertension • They found a normalization of blood pressure • increased nitrite/nitrate levels that usually are decreased in preeclamptic patients.Rytlewski K., Olszanecki R., Zdebski Z. (2001) 308-330.
  • L arginine on neonatal outcome in pregnancycomplicated by IUGR & gestational hypertension Pregnant women with gestational HT and IUGR • n= 42 received L arginine 3 g/day • n= 27 placebo L-arginine grp showed significantly higher birth weight at delivery, gestational age, and higher Apgar score Significantly lower number of cesarean sections in L-arginine grp than in placebo
  • Infant at delivery
  • Prolonged oral treatment with L-arginine in preeclampsia pregnancy Rytlewski et al. – Preeclamptic women at 29.2+3.4 weeks of gestation, – a prolonged supplementation with L- arginine (3 g for 3 weeks) – Significantly decreased blood pressure promoting endothelial synthesis and/or bioavailability of NO
  • NO donor in Preterm Labor NO to promote relaxation of smooth muscle, so NO donors have been employed as tocolytics. Maintain uterine quiescence during pregnancy. IV arginine infusion (30 g over 30 min) in women with premature uterine contractions transiently reduced uterine contractility. Oral arginine 7-15 gm /day may be effectiveHuman Reprod Update 1998;4:25-42.J Perinat Med 1996;24:283-285.

Text book of obs, 2004
  • Planning healthy meals Include all food groups in diet • Vegetables & fruits • Milk and dairy foods • Cereals & Grains • Meat, beans, and eggs • Fats and oils
  • Special concerns Caffeine • Limited intake during pregnancy • Excess caffeine can interfere with sleep and contribute to nausea and light- headedness • Can increase urination and lead to dehydration Vegetarian diets – low intake of iron, vitamin B12, vitamin D Pica • Strong urge to eat nonfood items such as clay, ice, laundry starch, or cornstarch • May affect intake of nutrients and can lead to constipation and anemia
  • Supplementary nutrition Personal food preferences, lifestyle habits and special needs may affect the intake of nutrients Essential vitamins lacking in diet or destroyed during cooking Nutritional supplements are one of the ways to fill the nutritional gap that may be arising due to improper diet It fills the gap by providing the vitamins, minerals, and other substances that may be missing out
  • Vital nutrients in breast milk Breast milk provides all the nutrients a baby needs to grow well for the first six months of life. The key nutrients in breast milk support the optimal growth and development of the baby and all organs and systems. Breast milk contains: • DHA and AA - building blocks of brain & eye development • Taurine & choline - support overall mental development & functioning. • Calcium and vitamin D for bone development • Many protective factors that protect the infant from infections • Fat, protein and carbohydrate, which are easily digested and absorbed
  • Mother’s nutrition influences the composition and quality of breast milk The nutritional needs of a breastfeeding mother is high - increased demand for Energy, Vitamins C, B12 • Nutrients consumed by mother is transferred to the growing baby to support its growth and development. • Nutritional deficiencies may develop during this period and affect both mothers and infants Maintaining a diet of fruits, vegetables, whole grains, lean meats, and dairy products regularly will help to meet nutritional needs Company Conf
  • Nutrition during lactation Human milk feeding is adequate as the sole source of nutrition for up to age 6 month providing that the maternal diet and reserves are adequate and a sufficient quantity is transferred to the infant Milk secreted in 4 months represents an amount of energy roughly equivalent to the total energy cost of pregnancy As with energy, recommended intakes for several vitamins and minerals are higher in lactation than in pregnancy Maternal nutritional adequacy does influence performance indexes both in pregnancy and lactation
  • Method to enhance activecomponents in food  Manipulating the diet to get maximum level of active components  Combination of food ingredients rich in nutraceuticals  Fortifying food with active ingredients  By fermentation of food products  Changing food habits to natural type of diet
  • Summary Evidence of nutritional intervention effectiveness • Balanced energy/protein supplementation • Zinc • Periconceptional folic acid intake • Iron supplementation • Calcium • Omega fatty acids • Iodine use • L -arginine
  • CONCLUSION Nutraceuticals are present in most of the food ingredients with varying concentration Concentration, time and duration of supply of nutraceuticals influence human health Manipulating the foods, the concentration of active ingredients can be increased Diet rich in nutraceuticals along with regular exercise, stress reduction and maintenance of healthy body weight will maximise health and reduce disease risk
