INTRODUCTION 3 In 2019, the infant mortality rate in India was at about 28.3 deaths per 1,000 live births, a significant decrease from previous years. Infant mortality rate in India 2019. (Published by H. Plecher , Oct 20, 2020) Globally, the infant mortality rate has shrunk from 63 infant deaths per 1,000 live births to 27 since 1990 and is forecast to drop to 8 infant deaths per 1,000 live births by the year 2100. India’s Rural Problem - With 32 infant deaths per 1,000 live births, India is neither among the countries with the highest nor among those with the lowest infant mortality rate.
ADJUSTMENT MADE BY THE NEWBORN INFANT All the needs, nutritional, biological and physiological, of the fetus is provided by the uterus during conception. After birth, the infant must carry out essential functions on his own: 1) respiration 2) temperature control 3) changes in blood circulation 4) with the first feeding infant is responsible for his own digestion, absorption, assimilation and excretion 4
GROWTH AND DEVELOPMENT IN INFANCY 1 ST year is critical as infant grows in weight and height - NB: about 6-7 lbs. (2.7-3.2kg) & 18-20 in. ( 48-51cm) - 1 st year: fastest growth until adolescence: BW is doubled by 5-6 months. & tripled by 12 months; birth length is increased by 24cm by the end of the year. 5
GROWTH AND DEVELOPMENT IN INFANCY 2. The body of infants is un-proportional 3. Bones and muscles are less formed and body forms more fat. - skeleton is mostly cartilage, body water composition is 75-80% - fontanelles close by the age to two. - cephalocaudal-proximodistal development - fat accumulates rapidly until 9 months of age 6
GROWTH AND DEVELOPMENT IN INFANCY 4. Brain development: fastest in the first two years. - brain development is faster than any other system up to age one - brain is 25% of its adult weight at birth will reach 70-75% of its adult size by age 24 months. 5. Teeth: 20 baby teeth will erupt, 6-12 months. Teething is complete at age 3. 7
GROWTH AND DEVELOPMENT IN INFANCY 6. Digestion and absorption - stomach capacity, 20ml at birth – 300ml by one year of age - ↓ salivary and pancreatic amylase, first month after birth - lactase, sucrose & maltase are well established at birth - proteolytic activity in infancy is the same as in adulthood (total qty digested per hour) - ↓ pancreatic lipase in the NB, bile acid pool is ½ of that of the adult 8
GROWTH AND DEVELOPMENT IN INFANCY 7. Renal function: the NB has functionally immature kidneys - ↓ glomerular filtration and reabsortion 8. Neuromuscular development Motor development is the development of control over bodily movements thru the coordinated activity of the nerves and the muscles. - suckles and smiles, 0-1 month age - vocalizes & controls head, 2-3 months - controls & rolls over, 4-5 months - sits briefly & crawls, 6-7 months - grasps & pulls up, 8-9 months 9
GROWTH AND DEVELOPMENT IN INFANCY - walks with support & stands alone, 10-11 months - starts to walk alone, 12 month++ The infant has a number of reflexes that work together to permit the intake of food Rooting reflex, causes the infant to turn his head when cheek is touched & to seek the nipple with his mouth Sucking reflex, vertical moments of the tongue and mandible to create negative pressure Extrusion reflex, anything that is put on the anterior part of the tongue is pushed out of the mouth 10
GROWTH AND DEVELOPMENT IN INFANCY Swallowing reflex, initially involves posterior part of the tongue and later develops to include the whole tongue. Rooting and extrusion ↓ until 3-4 months of age With ↑ age, there is gradual development of control over the lips, tongue and mandible, allows drinking from a cup with a little loss of liquid. Large & fine muscular maturation are important to the development of self-feeding; use of hands becomes more efficient from reaching or grasping with palms and whole hand to thumb-finger position. 11
PROGRESS OF GROWTH 12
NUTRITIONAL REQUIREMENTS IN INFANCY Nutritive needs - based on estimates of amounts supplied by breast milk or amounts laid down during growth - based on 750ml breast milk multiplied by its content - for older infants, the RNI is based in the amount of nutrient provided by both the breast milk and complementary foods. (refer to RENI for infants, FNRI-DOST, 2002) 13
RATIONALE FOR NUTRITIONAL REQUIREMENTS IN INFANCY A. Energy: the energy requirements per unit of body size in an infant’s first few months of life is very high but declines as the rate of growth ↓ Energy requirements per unit body of body rate is high because of the larger body surface area of infants compared to adults. The early months are characterized by high need of energy for growth and increased activity Breast milk will adequately meet the needs of infants below 6 months of age, after which complementation with other foods become necessary. 14
RATIONALE FOR NUTRITIONAL REQUIREMENTS IN INFANCY B. Protein: the need for CHON during the period of rapid skeletal and muscle growth of early infancy is relatively high; infants’ amino acid requirements are higher than those of adults. In addition to the 8 essential amino acids for adults, histidine is essential for infants; No adjustments for NPU are made for infants, since the dietary recommendation is in terms of breast milk 15
PROTEIN CHART 16
RATIONALE FOR NUTRITIONAL REQUIREMENTS IN INFANCY C. Fat soluble vitamins Healthy NB enters life with reserve of Vit A in the liver. RDA of 375 mg RE/day of Vit . A Vitamin D dietary intake should be assured Vit K usually is given at birth, 1mg/ kbw per day (FAO, 2002) D. Water-soluble vitamins: breast milk usually provides the RDA of water-soluble vits . If the mother’s diet is adequate. 17
RATIONALE FOR NUTRITIONAL REQUIREMENTS IN INFANCY E. Minerals: Ca:P ratio for infants is 1.3:1 The Fe content of a normal infant at birth is 75 mg/kg, biggest portion is found in the RBC Fe is accumulated in utero, in proportion to body size F. Water: Infants need about 1.5mL/kcal of energy expenditure; this need corresponds to the water-energy ratio in human milk. The min daily requirements for water is 800 & 1000mL in the 1 st & 2 nd months of life, respectfully 18
EXCLUSIVE BREASTFEEDING ADVANTAGE 19 Breast milk provides the ideal nutrition for infants. Breast milk contains antibodies that help your baby fight off viruses and bacteria. Breastfeeding lowers your baby's risk of having asthma or allergies . Plus, babies who are breastfed exclusively for the first 6 months, without any formula, have fewer ear infections , respiratory illnesses, and bouts of diarrhea . The AAP says breastfeeding also plays a role in the prevention of SIDS ( sudden infant death syndrome ).
MILK SUBSTITUTE FOR BREAST FEEDING 1. Breast milk substitutes: - cow’s milk - goat’s milk - mixtures containing no milk 2. Ways of stimulating human milk: - dilution with water or cereal water - boiling or any process to produce smaller curds - addition of weak acid (lactic acid, acetic acid, citric acid, etc.) to produce smaller curds and speed up protein digestion. 3. Proper sterilization is important ensure that the formula is free from contamination. 20
REQUIREMENTS FOR A SATISFACTORY ARTIFICIAL FEEDING Sufficient energy for infant’s n needs Sufficient CHON, VITS and water for growth and regulating body functions 21
METHODS OF STERILIZATION Standard aseptic method baby’s satisfied, 15-20 minutes feeding time Fall asleep promptly after each feeding, sleeps for 3-4 hours. Gain wt satisfactory, from week to week at about 142-227 grams per wk in the 5 month and then 113-142 grams per wk for the remaining month of the year 22
WEANING(Complementary Feeding) 23 If you're breastfeeding, feeding only breast milk up to around 6 months of age will help protect your baby against illness and infections. Waiting until around 6 months gives your baby time to develop so they can cope fully with solid foods. This includes solid foods made into purées, cereals and baby rice added to milk. Your baby will be more able to feed themselves. Your baby will be better at moving food around their mouth, chewing and swallowing it.
WEANING(Complementary Feeding) 24 Signs They'll be able to: stay in a sitting position and hold their head steady co-ordinate their eyes, hands and mouth so they can look at the food, pick it up and put it in their mouth by themselves swallow food (rather than spit it back out) The following behaviors can be mistaken by parents as signs that their baby's ready for solid foods: chewing their fists waking up in the night (more than usual) wanting extra milk feeds
WEANING(Complementary Feeding) 25 Weaning an infant is a gradual process. The American Academy of Pediatrics (AAP) recommends feeding infants only breast milk for the first 6 months after birth. After 6 months, the AAP recommends a combination of solid foods and breast milk until the infant is at least 1 year old Starting solid foods too soon can be hazardous, so an infant should not be fed solid food until he or she is physically ready.
WEANING(Complementary Feeding) 26 Start solid feedings (1 or 2 tablespoons) of iron-fortified infant rice cereal mixed with breast milk or formula, stirred to a thin consistency. Once the infant is eating rice cereal regularly, you may introduce other iron-fortified instant cereals. Only introduce one new cereal per week so that intolerance or possible allergies can be monitored.
INTRODUCTION OF COMPLEMENTARY FEEDING BEIKOST (German word for “foods other than milk or formula”) - nutrition: 6 month age, nutritional insufficiency of milk diet - physiological readiness: ability to handle food other than milk is dependent * secretion of enzymes for digestion of starch & un- emulsified fats * gastric acidity is increased * maturity of the kidney function 27
ORDER OF ADDING SOLID FOODS 1. Cereals: - first solid food - approx 6 months - must be well-cooked, well strained - a portion of the formula may be added - crisp toast, biscuits may be given when teeth begin to appear 2. Fruits: - mashed ripe bananas, ripe papaya, ripe mango (6 months) for chewing 28
ORDER OF ADDING SOLID FOODS 3. Vegetables: - cooked very soft, mashed or passed thru a sieve - on the 7 th months - carrots, squash, potatoes. 4. Eggs: egg yolk 7 th month, 11 th month whole egg 5. Mango, dried beans, veggie soft & strained, 6 th month 6. meat, fish and poultry, mechanical diet, 6 th month 7. Other foods: custards, plain ice cream.8 month 29
