Having used cloth diapers on my kids for the past five years, I had mixed feelings about this piece in Thursday’s Des Moines Register. Reporter Erin Crawford agreed to try cloth diapers for a short time.

While it’s great that she let readers know there are better options today than pins and rubber pants, I wish she had talked more about the health and environmental benefits of using cloth diapers.

Her husband complained that the cloth diapers seemed “unhygienic.”

Apparently he doesn’t realize that disposable diapers are full of chemicals that may be absorbed through baby’s wet skin, or that disposable diapers send more untreated sewage to our landfills (click the link to see the references in the footnotes):

Of more serious concern are the toxic chemicals present in disposable diapers. Dioxin, which in various forms has been shown to cause cancer, birth defects, liver damage, and skin diseases, is a by-product of the paper-bleaching process used in manufacturing disposable diapers, and trace quantities may exist in the diapers themselves.6

And what about the material that makes “superabsorbent” diapers so absorbent? If you’ve ever used disposable diapers, you’ve probably noticed beads of clear gel on your baby’s genitals after a diaper change. Superabsorbent diapers contain sodium polyacrylate, which absorbs up to 100 times its weight in water. Sodium polyacrylate is the same substance that was removed from tampons in 1985 because of its link to toxic shock syndrome.7 No studies have been done on the long-term effects of this chemical being in contact with a baby’s reproductive organs 24 hours a day for upwards of two years.

Neither type of diaper can claim to be more sanitary. In the early 1990s, right around the time many states were considering offering incentives to hospitals and daycare centers to switch to cloth diapers, disposable diaper manufacturers attempted to prove that cloth diapers contribute more to the spread of bacteria. In fact, it is the caregiver’s hand-washing habits, and not the type of diapers, that is the deciding factor. “The research in this area was funded by special interests,” points out Janet Primomo, RN, PhD, associate professor of nursing at the University of Washington, Tacoma. “It’s not a question of whether cloth or disposables are more sanitary–it all depends on practices and procedures, such as hand washing habits and what kind of storage containers are used.”

There is, however, a more serious threat of contamination from disposable diapers, because of human sewage going into landfills. The disposal of human waste in residential garbage is technically prohibited, and instructions on disposable diaper packaging recommend that you shake out any fecal matter into the toilet before disposing of it; but in practice this is almost never done. Live viruses in the feces, such as the polio vaccine, can live in landfills for a long period, and if there were ever any leakage, could potentially contaminate a community’s drinking water. So far, there has been no evidence of contamination–this is more of a concern in Third World countries, where landfills aren’t as well constructed, and disposable diapers are being marketed aggressively.

Here is more troubling information about the potential effects of chemicals in disposable diapers:

1999 A study, “Acute Respiratory Effects of Diaper Emissions,” in the October issue of Archives of Environmental Health, finds that laboratory mice exposed to various brands of disposable diapers suffered eye, nose, and throat irritation, including bronchoconstriction similar to that of an asthma attack. Chemicals released from the diapers included toluene, xylene, ethylbenzene, styrene, and isopropylbenzene, among others. The lead author of the study, Dr. Rosalind C. Anderson, advises asthmatic mothers to avoid exposure to these chemicals. Asthma rates are on a sharp incline in the US and worldwide, particularly among poor and inner-city children. Six leading brands of cotton and disposable diapers are tested. Of these, three are found not to affect the breathing of mice: American Fiber and Finishing Co., Gladrags organic cotton diapers, and Tender Care disposable diapers. Cloth diapers are not found to cause respiratory problems among mice.

I’ll never understand why many people have such a hangup about cloth diapers, which also save parents money on top of the health and environmental benefits. It’s just another load of laundry.
