ANT202H5 Lecture Notes - Lecture 15: Medullary Cavity, Specific Developmental Disorder, Prenatal Development
Document Summary
Development physical changes of human life, leading to maturation. Undernutrition inadequate intake of essential nutrients needed to survive and thrive. Measured through child growth, mortality, and infectious disease rates (2 weeks pior) Death 35% of infant/child (birth to 5 years) Kills by increasing severity of childhood infections. Growth stunt short height for age. Small body size in adult (under nutrition, infection during childhood) Height slow growth during childhood and adolescence. Prolonged period of growth = + 10% Still 10% decrease in height (vs well nourished) 0 - 10 years = 20% delay. Within population = delay among undernourished (less than 15%) Between population = late as 18 19 years. Low birth weight retarded prenatal growth. Stunting adaptive scarce resources redirected to growth and maintenance of critical systems. Compromise among physiological systems and environment stressors. Higher risk of mortality during child birth. Poor growth of girls = intergenerational effect persisting in their children.
