A low birth weight is less than 5.5 lbs. High birth weight is more than 8.5 lbs, or greater than 90 percentile • Define Adequate Intake (Dietary Reference Intakes) for infants. Infants don’t have a dietary reference intake, they have adequate intake that are followed because each child is different and have different needs Average nutrients for thriving/healthy babies Higher in All vitamins associated with growth Vitamin D – 10x adults – needed for bone growth Vitamin C – 5x adults – needed for bone growth Vitamin A – Iodine– 7x adults Needs are higher during 0-6months compared to 6-12months Energy (100kCal/kg) adult’s 40kCal/kg Protein (2.0g/kg) - adults need 0.5g/kg Fat (50% of total Kcal) – adults <35% • Describe methods used to physically assess growth in infants. Some of the methods used to assess growth are measuring birth weight, length, and head circumference for gestational age • Recognize a normal pattern of growth for an infant (height / weight) over a 12- month period as plotted on a weight / age and height / age growth chart. On the chart, a child weight (measured on bottom) and length (measured on top) follows a curve. If the child’s growth pattern falls under the curve, the child is at risk and needs to be watched. No child, even those in the 95% should evergo under his/her curve. • Describe the growth rate of an infant during the first year of life. Compare the metabolic rate/ kcal needs of an infant to an adult....
