Nutritional Risks Associated with
Substance Use






Alcohol
Cocaine
Heroin
Marijuana

Alcohol

Alcohol contains calories!!

Interferes with digestion, storage,
utilization and excretion of nutrients

Alcohol affects maternal and fetal
nutrition

Alcohol

Alcohol contains calories!!

Interferes with digestion, storage,
utilization and excretion of nutrients

Alcohol affects maternal and fetal
nutrition
11
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
12
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
13
Growth patterns of infants exposed to
cocaine and other drugs in utero
Author: 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
J Amer Diet Assoc 1994;94(9):999

Heroin



Associated with  birth weight, prematurity and
IUGR
Common symptom of opiate abuse: constipation
May be poorly nourished




Vitamin deficiencies
Iron deficiency anemia
Folic acid deficiency anemia
May experience food cravings
15
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 ?

marijuana and those who did not
16
Tobacco




Author: Ballard
Setting: Children’s Hospital, Cincinnati, OH
Sample: 6 infants exposed to methadone
Observations:
1.Feeding breastmilk associated with  withdrawal symptoms
2.Frequent small doses from breastmilk shown to be more
effective than large dose
3.Breastmilk may be most effective method in providing
methadone to infants

Nutrition Education is Positively Associated with
Substance Abuse Treatment Program Outcomes
Author: Grant et al
Setting: Cross-sectional survey
Sample: 152 registered dietitians
Outcome:
1. Positive associations found when nutrition education services
incorporated into substance abuse tx programs
2. Group education/substance abuse education improved ASI
scores improved
3. Individual nutrition/substance abuse education ASI scores
improved by 99% (P<.05)
J Am Diet Assoc 194;94(9):999
57
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
58
Brief Intervention for Alcohol Use
by Pregnant Women
Author: 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
Am J Public Health 2007;97:252
59
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
