Alcohol
Alcohol contains calories!!
Interferes with digestion, storage, utilization and excretion of nutrients
Alcohol affects maternal and fetal nutrition

Alcohol Affects to Fetus Impairs placental nutrient transport Glucose transport necessary for fetal brain
development Prenatal insulin resistance may lead to glucose
intolerance later in life Folate and zinc deficiency may lead to neural tube
teratogenesis Animal studies found that the effect of alcohol was
not as severe when maternal diet adequate in zinc

Cocaine Little is known about effects of cocaine on
maternal and fetal nutrition Interferes with appetite Causes maternal and fetal vasoconstriction
→ fetal hypoxia nutrient supply → IUGR

Growth patterns of infants exposed to cocaine and other drugs in uteroAuthor: Harsham et al
Setting: Northern California
Sample: 31 infants exposed to drugs in utero
Outcome:
1. Birth weight, birth length were significantly lower than NCHS
2. By 6 months, no significant differences for weight, but differences in length

Marijuana
Associated with birth weight and length Conflicting study results have not shown
any nutrition-related effects of marijuana use in pregnancy Weight gain ? Weight loss ? No difference in women who smoked
marijuana and those who did not

Associated with IUGR Nutrition-related effects
Lower availability of calories ↑ iron requirements availability of certain nutrients (B12, amino
acids, vitamin C, folate, zinc

Caffeine
Affects the CNS 15 minutes after ingestion Caffeine intake > 300 mg/day linked to ↑ 1st
trimester abortions Moderate to heavy caffeine linked to:
Lower birth weight ↑ risk of preterm labor Delayed conception absorption and ↑ urinary losses of vitamin B1, zinc,
iron and calcium

Brief Intervention 10 – 15 minutes sessions of counseling delivered
by non-alcohol abuse specialists Shown to be low cost, effective treatment
alternative for alcohol use Uses time-limited, self-help strategies to promote
reductions in alcohol use in nondependent individuals or to facilitate referral to specialized treatment programs in alcohol-dependent persons

Brief Intervention for Alcohol Use by Pregnant WomenAuthor: O’Connor, Whately
Setting: WIC Program in Southern California
Sample: 250 pregnant women who reported drinking alcohol
Outcome:
1. Women in brief intervention group were 5x more likely to report abstinence after intervention
2. Newborns from brief intervention had higher birth weights and birth lengths
3. Fetal mortality rates were 3x lower (0.9%) in intervention group
4. In both groups, women reduced their drinking substantially

Summary
Use of legal and illegal substances can affect the nutritional status in pregnancy
Positive nutrition may improve pregnancy outcome
All pregnant substance abusing should receive comprehensive nutrition assessment and counseling by a qualified dietetic practitioner
Nutrition services and education should be part of the multidisciplinary care
Breastfeeding not totally contraindicated in substance use
