-Risk Analysis -
•Knowing which risks are worth taking
•How to minimize chance of harm
•Teratology: science of risk analysis
•Threshold effect: when a teratogen is harmless in small doses but becomes
harmful at a certain level (threshold)
-remains controversial
-Applying the Research -
•Fetal Alcohol Syndrome (FAS)
-a cluster of brith defects including abnormal facial characteristics, slow physical
growth, and retarded mental development
-may occur in the child of a omen who drinks alcohol while pregnant
-Preterm of Slow Growing? -
•Preterm
-birth that occurs at 35 or fewer weeks after conception
-usually associated with low birthweight
•Small for Gestational Age (SGA)
-birthweight is significantly lower than expected, given the time since conception
-Low Birthweight -
•less than 2,500 grams (5.5 pounds) at birth
•United States
-steady increase in LBW over the past 25 years
-8% of newborns are seriously underweight
-more susceptible to teratogens, higher birth risks, lower survival rate
•Causes:
-teratogens, like tobacco and drugs use
-genetic predisposition
-low weight gain in birth mother
-inadequate nutrition
-vitamin deficiency
-What About the Father? -
•Indirect influence of risk for adverse birth outcomes
-father’s attitude
-father’s behavior
-relationship between mother and father
-Complications During Birth -
•Cerebral Palsy:
-damage to the brain’s motor center
-speech and/or muscles are implied
-caused not just by birth procedures (ex. use of forceps) but also genetics,
teratogens, and maternal infection
•Anoxia:
-lack of oxygen
-over time can cause brain damage or death
-The New Family: Mothers -
•About half of all women experience physical problems after birth

Document Summary
Applying the research : fetal alcohol syndrome (fas) A cluster of brith defects including abnormal facial characteristics, slow physical growth, and retarded mental development. May occur in the child of a omen who drinks alcohol while pregnant. Birth that occurs at 35 or fewer weeks after conception. Usually associated with low birthweight: small for gestational age (sga) Birthweight is signi cantly lower than expected, given the time since conception. Low birthweight : less than 2,500 grams (5. 5 pounds) at birth, united states. Steady increase in lbw over the past 25 years. More susceptible to teratogens, higher birth risks, lower survival rate: causes: What about the father: indirect in uence of risk for adverse birth outcomes. Complications during birth : cerebral palsy: Caused not just by birth procedures (ex. use of forceps) but also genetics, teratogens, and maternal infection: anoxia: Over time can cause brain damage or death.
