Nutritional challenges for women who use alcohol and other drugs in pregnancy. Amy Sanders Dietitian The Royal Women’s Hospital VAADA Conference 13th February 2007
Overview • Role of dietitian • Nutritional needs of pregnant women • Impact of D&A use • Barriers to accessing care • Nutrition audit • Nutritional recommendations • Health promotion strategies
Women’s Alcohol and Drug Service • Specialised maternity and drug and alcohol service for women with complex drug issues. • Multidisciplinary team: • Midwifes, social workers, psychologist • Specialist support from obstetricians, pediatrician, pharmacist, dietitian, psychiatrist and housing worker. • “A Multi disciplinary team working collaboratively can achieve optimal pregnancy, birth and parenting outcomes for each woman and her family”(National clinical guidelines 2006)
Role of Dietitian • Optimise the nutritional status for healthier pregnancy • Screens all clients - weekly outpatient clinics • Inpatient methadone stabilisation program • Health professional training days • Attends team meetings • Few dietitians working in this area of need ? • Lack of published nutrition guidelines • Need to advocate for equal service opportunities.
Referral indicators • Anaemia (iron, folate, B12) • Malnourished, thin women • Lack of weight gain or too much weight gain • Nausea, vomiting, constipation, appetite problems • Poor baby growth • Veiled, dark skinned women • Vegetarians • Previous GDM or PCOS • History disordered eating • Recent pregnancies • Multiple pregnancies Most of our women with D+A issues fit nearly all of these referral indicators !!
Nutritional needs of pregnancy • Specific nutrient requirements - protein, iron, folate, calcium and other vitamins and minerals • Awareness of listeria, mercury and fish, Vitamin A, caffeine • Optimal nutrient stores • Adequate maternal weight gain • High risk women refer to dietitian • Simple dietary advice specific to individual needs.
Nutritional effects of D+A use • Appetite suppression • nutrient uptake • nutrient bioavailability • nutrient losses/malabsorption • Altered nutrient synthesis, activation and utilisation • Impaired nutrient metabolism and absorption • nutrient destruction • metabolic requirements of nutrients • Delayed gastric emptying Eg. Marijuana ↓ zinc Cigarettes ↑ iron Alcohol ↑ thiamine Amphetamines ↑ metabolic rate Opiates ↓ GI motility
‘Lifestyle’ effects of D+A use • Limited finances • Homelessness • Poor self care • Reliance on take away foods • Chaotic meal patterns • Poor food safety practices • Reduced self awareness of hunger-satiety
Nutritional challenges iron folate bowels housing $$ dental BMR nutrient deficiency Vit C stress thin LOA Poor nutritional status calcium Pregnancy demands N+V Effects of drug use Lifestyle Factors anemia food skills over weight Compromises nutritional status Effects maternal health + fetal outcome
Barriers for care • Food insecurity • Poor nutrition knowledge & skills • Knowledge of nutrition services available • Suitability of appointment times • Tiredness, anxiety, depression • Stage of change
Nutrition audit • n = 50 pregnant women attending WADS (March 04-05) • Average age 29 years • Polydrug use + • 62% on methadone (n =31) • 24% buprenorphine (n = 12) • 56% illicit drugs (heroin) • 86% smoking tobacco • 56% cannabis use • 18% alcohol use
Nutrition audit • First clinic contact - 19 wks (average) • First dietitian contact - 22 wks (average) • Range 7 - 38 weeks • Average 4 sessions with dietitian • Range 0 - 10 sessions • Equates to monthly reviews • Average gestation delivered 37.8wks • Average infant birth weight 2849g
Nutrition recommendations Underweight women • 40% underweight pre preg (BMI <20) Risks • Underweight → strong predicator of poor pregnancy outcome (↑ prematurity,↑ LBW) • Low BMI → more dependent on nutritional intake to achieve good weight gain. Recommendations • Assess pp BMI • Discuss normal weight gain and monitor • Dietary advice - ↑ meal regularity, ↑ snacks, ↑nutrient dense foods, trial oral nutritional supplements.
Nutrition recommendations Maternal weight gain • Suboptimal wt gain (9kg) • Slow in 2nd trimester • 25% poor wt gain (<5kg) LBW <2.5kg Risks • Adequate weight gain = optimal pregnancy outcome • Low maternal wt gain ↑ LBW Recommendations • Monitor weight • Aim 12.5 – 18kg total weight gain (low BMI)
Nutrition recommendations Iron Deficiency • 33% early pregnancy & 60% later pregnancy Risks • ↑ preterm delivery, ↑ fetal growth retardation • Tiredness access to care • ↑ risk infection, poor concentration Recommendations • Routine ferritin • Iron therapy - monitor tolerance/compliance. • ↑ dietary iron & consider factors affecting absorption
Nutritional recommendations Vitamin D deficiency • 6 of 7 women deficient • Recent data - 58% deficient (n =34) Risks • Infants dependant on maternal Vitamin D status • May affect infant skeletal growth Recommendations • Test Vitamin D • Supplement deficient mother & baby if breastfed • Encourage small amounts of sunlight exposure
Nutritional recommendations Nutritional Supplements • 66% iron, 58% folate, 28% multivitamins, 14% VitB Barriers • Women confused what to take • Financial costs • Poor compliance → GI effects Recommendations • Advise on appropriate supplementation – mv + iron • Avoid high doses Vitamin A & herbal preparations • Consider cheaper alternatives
Nutritional recommendations GI Symptoms • Constipation most severe problem (50%) • 22% laxatives, 20% fibre supplements Risks • desire to eat→ quality of diet Recommendations • ↑ dietary fibre & ↑ fluids • Fibre supplements, then laxatives • Review iron therapy • Encourage gentle daily exercise
Nutritional recommendations GI Symptoms • Nausea and vomiting common (40%) • 12% antiemetics Risks • Dehydration, electrolyte imbalances, nutrient intake • Loss of 5% pp weight → negative implications Recommendations • Small frequent meals, adequate fluids, avoid empty stomach, avoid rich/spicy/fatty foods • Review of pharmacotherapy & antiemetics
Nutritional recommendations • Dietary Ax • 12% diet adequate for pregnancy • Poor iron intake (50%) • Irregular meals • High reliance takeaway food • Poor fruit and vegetable intake • Recommendations • Simple practical meal and snack ideas • Encourage regular meal pattern/snacking • ↑ Iron rich foods • Budget eating, shopping and cooking hints • Healthier takeaway choices
Health Promotion Strategies • Dietitian to screen all women • Educate: - nutrition for pregnancy - listeria, mercury, caffeine, VitA - drug effects on nutrition - symptom management • Recommend multivitamins • Assistance with crisis food support, community food programs, budget shopping • Refer to dental services • Monitor weight, biochem, symptoms & diet • Multidisciplinary team meeting
Health Promotion Strategies • Specific nutrition resources • “Healthy pregnancy hints” & “Eating well and pregnancy” • Visual displays • Nutrition posters & food/product displays • Oral nutritional supplement • Sustagen®, Ensure ®, Enlive Plus® • Recipe books - quick easy meals • Cooking classes
Conclusion • Women attending a maternity D+A unit are at high nutritional risk • Nutritional deficiencies can be caused by a number of direct & indirect effects of drug use. • These women do not tend to seek nutritional support but are keen for advice • Dietitians can assist multidisciplinary teams to promote better nutrition. • By optimising nutritional status in pregnancy we can improve health outcomes for women and babies.
