Nurse midwifery environmental health

Nurse-Midwifery & Environmental Health

  • Core competencies

    • Environmental influences on pregnancy planning

    • Environmental influences on pregnancy outcomes

But how can a practitioner translate this into practice?

Assessment Tool


Carbon monoxide

Carbon Monoxide

  • Odorless, colorless, tasteless

  • Symptoms of poisoning similar to those of pregnancy – fatigue, nausea, vomiting

  • First trimester appears to be time of greatest fetal sensitivity

  • First trimester exposure associated with intrauterine growth restriction, lower birth weight, preterm delivery


Carbon monoxide1

Carbon Monoxide

  • Prenatal exposure may negatively impact lung function in children with asthma

  • Decreased lung function found in:

    • African American children

    • Children diagnosed prior to age 2

Mortimer et al. 2008


Carbon monoxide sources

Carbon Monoxide Sources


Exposure prevention

Exposure Prevention

  • Do not idle automobiles in the garage

  • Make sure combustion heating sources are working properly and are properly vented

  • Have carbon monoxide detectors on every level of house with combustion heating

Drinking water

Drinking Water

The first question to ask:

  • Are you on a private well or public drinking water supply?


Public drinking water

Public Drinking Water

  • Water companies test the water

  • The findings are made public annually

    (Consumer Confidence Report)

  • In emergency situations, an alert is to be made.


Bisphenol a

Bisphenol A


Bisphenol a1

Bisphenol A

  • Originally produced in 1891

  • Estrogen-like compound

  • When DES was found to be more estrogenic, its use as a pharmaceutical was discontinued

  • Was rediscovered when chemists found it could be mixed with a polymer to produce polycarbonate plastic


Myriad of consumer uses

Myriad of Consumer Uses

  • Baby bottles

  • Metal can liners

  • Water bottles

  • Food containers

  • Dental products

  • Compact discs


Concerns

Concerns

  • Ubiquitous in humans

  • Federal safety assessment based on two studies

  • Health effects occur at very low dose exposure


Fda bisphenol a

FDA & Bisphenol A

  • Safety assessment flawed

  • Based on two studies

    • Both studies funded by the chemical industry

    • One has never been published

    • Other with questionable scientific methodology

  • Approx. 100 peer-reviewed studies came to a different conclusion

Effects of bpa exposure

Effects of BPA Exposure

  • Polycystic ovarian syndrome

  • Endometrial changes

  • Miscarriage

  • Decreased hormonal levels in men needed for sperm formation

  • Breast and prostate cancers

  • Infertility in men and women

  • Insulin resistance


Infant formula

Infant Formula


Decreasing bpa exposure

Decreasing BPA exposure

  • Avoid #7 plastics

  • Plastics with #1, #2, and #4 are safer

  • Do not use liquid infant formulas

  • Avoid canned foods

  • If using metal water bottle make sure it does not have an epoxy liner!

Smoking pregnancy

Smoking & Pregnancy

  • Smoking during pregnancy

    • Doubles the risk of having a low-birthweight baby

    • May increase risk of congenital heart defects

    • Increases risk of preterm delivery

    • Increases risk of placenta previa & abruption

    • Increases risk of premature rupture of membranes (PROM)


Smoking pregnancy1

Smoking & Pregnancy

  • If a woman quits smoking even as late as the second trimester, her risk of having a low-birthweight baby is the same as if she had never smoked.

Personal care products

Personal Care Products

  • Over 10,000 different chemicals used in personal care products

  • Only 11% have been tested for safety

  • In a 2004 survey, adults used an average of 9 products a day for a total of 126 different ingredients daily

Personal care products1

Personal Care Products

  • Phthalates – Used as plasticizer in PVC, fragrances, solvents

  • Found in hairspray, shampoo, nail polish

  • Impacts fetal development – boys especially susceptible


Personal care products2

Personal Care Products

  • Read Labels!

  • Don’t buy products listing “Fragrance” or “Phthalate” in the ingredients

Reducing exposure

Reducing Exposure

  • Choose low/no VOC paint

  • Let someone else do the renovations and stay away until the room is well-ventilated

  • Allow house to air out frequently

  • If buying new furniture for nursery - avoid pressed wood, stain resistant upholstery

PBDE

  • Polybrominated diphenyl ethers (PBDEs)

  • Persistent in the environment

  • Very high levels found in breastmilk of U.S. women

  • Health effects – reproductive, developmental (especially neurological)


Pbde in breastmilk

PBDE in Breastmilk

Schecter et al 2003, Mazdai et al 2003, Kalantzi et al 2004, compiled by NRDC

Reducing exposure1

Reducing Exposure

  • Vacuum and dust at least once a week – use HEPA filter if possible

  • Replace furniture with crumbling cushions or cover with fabric

  • If possible, do not reupholster foam cushions

  • Be careful if replacing carpet

  • When replacing products find out what kind of fire retardant used – avoid brominated
