Health Threats to Children
The most critical threats to the lives of children
under age five globally are:
 Pneumonia
(18%)
 Diarrheal diseases (15%)
 Pre-term birth complications (12%)
 Birth asphyxia (9%)
 Under-nutrition is an underlying cause of ~1/3 U5M
Sub-Saharan Africa > 50% deaths due to malaria,
diarrhea, pneumonia

Infant Mortality
Lowest rates for mothers in their late 20’searly 30’s
 Adolescent mothers have the highest
infant mortality rate in US
 Infant mortality is


83% higher in unmarried mothers
 Higher in smokers
 Higher in pre-term infants
Maternal Mortality

All US women: ~12.7 deaths/100,000 live
births
 White
women: 10.5 (risen)
 Black women: 28.4
 Hispanic: 8.9
 2007
data
Infant Mortality

Many of the deaths can be attributed to:

Poor maternal nutrition
 Low birth weight/pre-term babies
 Lack of prenatal care



Lack of health insurance
SIDS
Nutrition before and during pregnancy is
critical to the health of baby
Nutrition During Pregnancy
Time of significant growth for mother and
fetus
 Goal is to start pregnancy with full
nutritional stores

Nutrition During Pregnancy

Of greatest importance pre-pregnancy are
having adequate levels of:
 Folate
 Iron

Weight Gain

Insufficient maternal weight gain increases
risk of low birth weight baby (LBW)
 LBW
= birth weight less than 5 ½ pounds
 LBW are 40x more likely to die in the first year
of life than healthy weight baby
 1 in 12 babies in US are of LBW

Black 2x as likely to have a LBW baby as
white/Hispanic
“Morning” Sickness (MS)

~75% of women experience MS during the
first months of pregnancy
 May
be triggered by foods, smells, thought of
food

May be related to enhanced sense of smell
 Iron
supplements may trigger nausea in some
 May occur any time of day

Suggestions?......
Weight Gain

Sharp weight gains may signal:
 Water
retention
 Pregnancy induced hypertension ~7%
pregnancies
May be associated with low vitamin D levels
 Preclampsia – mild hypertension
 Eclampsia – more serious


Previously called toxemia
Eclampsia

At greatest risk:
 Over
35 and under 17
 Carrying twins or more!
 Family/personal history of
 Diabetes
 First pregnancy
 African American descent
Eclampsia

Symptoms/consequences
 Edema
 Hypertension
 Protein
in urine
 Kidney failure
 Liver damage
 Convulsions and death of mom and/or baby
Eclampsia

Treatment
 Bed
rest
 Magnesium sulfate (diuretic)
 Deliver baby
Nutritional Needs - Pregnancy

Protein
 Needs
increase by 25 g/day
 1.1 g protein/kg body weight
 Page
521 has a good summary of all
nutritional needs
Minerals

Minerals
 Calcium,
no increase
The number of calcium binding proteins increases
in the SI. This results in increases absorption.
 Critical that diet includes 3-4 servings of calcium
rich foods each day.

 Iron
needs nearly double
 Zinc needs go by ~30%

Zinc is found in proteins
Vitamins

B Vitamins
 RDA
for all goes up by ~30%
 Folate needs go up by 50%
 Eat more vegetables and select whole grain
products.

Vitamin C
 Need
a little extra
Vitamins

NO EXTRA needed for:
 Vitamin
D
 Vitamin A in the form of active vitamin A

DO NOT TAKE VITAMIN A SUPPLEMENTS
DURING PREGNANCY


Increases the risk of serious birth defects
Extra beta-carotene (plant form of vitamin A) is fine
and probably good for you
Practices to AVOID

Smoking
 Increases
risk of LBW, miscarriages, infant
death

Caffeine (?)
 Heavy
coffee drinking may lead to and
increased risk of LBW
 High levels of caffeine may increase the risk
of miscarriage
Practices to AVOID

Fasting or low/no carbohydrate diets
 Ketones

may slow fetal brain development
Aspartame (?)
 Probably
OK as long as mom does not have
PKU
 Recommend no more than 1 Liter of diet soda
per day
Practices to AVOID

Eating unpasteurized dairy products, raw
cabbage, raw meats
 Brie,
feta, blue cheeses, goat cheeses
 Increased risk of Listeria
Flu-like symptoms
 May cause miscarriage and death of mom

Practices to AVOID
Vitamin megadoses
 Alcohol

 Increases
risk of fetal alcohol syndrome (FAS)
FAS

Brains of 6 week old infants
No FAS
FAS
FAS

Physical Characteristics
 Broad,
short, flat nose
 No dimple above lip
 Narrow eyes
 Flat face
Practices to AVOID

Illegal Drugs
 Marijuana
and cocaine can increase risk of:
LBW
 Nervous system disorders
 Irregular heart rate
 Drug withdrawal symptoms in infant
 Neonatal death

Practices to AVOID

Over the Counter Medications (most)
 Can
cause complications during pregnancy
and increase risk of birth defects
 No aspirin or ibuprofen in the last trimester

Both interfere with blood clotting
Nutrition During Lactation

Energy needs
 ~+500

kcal/day for the first 6 months
Maternal weight loss during lactation
 Recommend
a loss of a maximum of 1-2
pounds/month
Nutrition During Lactation

Vitamins needs go up for:
 Vitamin
A, E and C
 B vitamins in general
Nutrition During Lactation

Minerals
 Iron

Return to pre-pregnancy levels
 Calcium


Increased absorption takes care of needs
Adequate fluid intake is critical
Breast Feeding Benefits



First 2-3 days breast milk contains colostrum
 Contains antibodies that protect baby from
infection
Reduces incidence of allergies and eczema.
Lowers risk of obesity later in life
Breast Feeding Benefits

Reduces the risk of urinary tract infections,
inflammatory bowel disease, gastroenteritis, ear
infections, and respiratory infections.
 Formula-fed
infants are three times more likely to
suffer from ear infections than breastfed babies, and
up to five times more likely to suffer from pneumonia
and lower respiratory-tract infections.
Breast Feeding Benefits

Causes less stomach upset, diarrhea, and
constipation than formula.

Lessens the risk of SIDS.
 Although the connection is unclear, breastfed
infants account for only half as many SIDS
cases as formula-fed infants do.
Feeding Infants

Breast milk is best source of nutrition for
an infant
 Assumes
mom is well fed
 Can be the only source of nutrients for the 1st
4-6 months
Infants

Breast fed babies are generally given
vitamin D supplements
 Especially
important if limited sun exposure or
if mom is vitamin D deficient
 Issues occur most often with dark-skinned
mom/baby
Breastfeeding
Pros?
 Cons?

Feeding Infants

NEVER SCOLD a new mom who decides
not to breastfeed!
Feeding Infants

A baby grows faster in the first year of life
than ever again
 Birth
weight doubles by 4-6 months
 Birth weight triples by age 1
Formula

Formula guidelines:
 Should
be iron enriched
 Never water down
 Do not add cereal to the formula
Infants cannot digest starch
 Cereal acts as a fiber and not a source of nutrition

Adding Solids to the Diet

At ~4-6 months the baby’s iron store will
be depleted
 At
this time (usually) the baby:
can sit up on his/her own
 has doubled his/her birth weight

 Any
earlier introduction of solid foods can
increase the risk of allergies and obesity later
in life
Adding Solids to the Diet

Start with iron enriched rice cereal first
 Fewer

allergies to rice than other grains
Add foods one at a time
 Vegetables
and fruits first
Adding Solids to the Diet
8-10 months add: egg (?) and potato, meat
(last)
Eggs are controversial! I checked a number of
resources. Many list adding cooked eggs to the
diet at this point.
 Most recommend adding eggs to the diet at 12
months


Concern is that baby will develop an allergy to the
proteins in the egg white
Adding Solids to the Diet
Avoid sweetened baby foods
 NO HONEY

 May
carry botulism
8-9 Months of Age

Baby can be fed “family food”
 Lightly
seasoned
 Cooked
 Finely chopped

Allow some self-feeding
 Messy,
but good for baby’s development
Messy Babies!
Feeding a 1 year Old
OK to add whole cow’s milk to diet
 Growth rate slows and caloric needs don’t
go up much

 So
don’t stress if your soon to be toddler isn’t
eating as much as you think he/she “should”
Feeding a 1 year Old

Need increased muscle and bone
strength to support walking
 Protein
needs go up
 Calcium and phosphorus needs go up
2-3 glasses of milk are sufficient
 More may lead to “milk anemia”

Feeding a 1+ year Old

Remember – children have small
stomachs, therefore it’s important that all
that goes in be of high quality
 All
foods should be nutrient dense
