Insecticide-treated bed nets reduce infant deaths in Democratic Republic of Congo

07.09.2009
Giving insecticide-treated bed nets to nearly 18,000 mothers at prenatal clinics in the Democratic Republic of Congo prevented an estimated 414 infant deaths from malaria, a study by University of North Carolina at Chapel Hill researchers concludes.

Giving insecticide-treated bed nets to nearly 18,000 mothers at prenatal clinics in the Democratic Republic of Congo prevented an estimated 414 infant deaths from malaria, a study by University of North Carolina at Chapel Hill researchers concludes.

The bed nets cost about $6 each. When costs for transporting and distributing the nets and educating people how to use them are factored in, it cost just over $411 per infant death prevented. In addition, the intervention prevented an estimated 587 low birth weight deliveries, which in turn reduced long-term disability.

“This is an extremely cost-effective intervention,” said Sylvia Becker-Dreps, M.D., M.P.H., assistant professor of family medicine in the UNC School of Medicine and lead author of the study, which is published in the September 2009 issue of the American Journal of Tropical Medicine and Hygiene.

"In fact, it approaches the cost effectiveness of measles vaccination and is far more cost effective than prevention measures that are routine in the U.S."

The study stems from a project Becker-Dreps worked on while pursuing her Master of Public Health degree in the UNC Gillings School of Global Public Health. Andrea K. Biddle, M.P.H., Ph.D., an associate professor in the Gillings School, was one of her mentors on the project and is one of the study’s co-authors, along with three other Gillings School faculty.

In the project, study co-author Frieda Behets, Ph.D., associate professor of epidemiology at the Gillings School, helped 28 clinics in Kinshasa, the capital and largest city in the Democratic Republic of Congo, implement a program to prevent mother-to-child transmission of HIV. As part of that program, 17,893 pregnant women were given long-lasting, insecticide-treated bed nets for free.

Malaria, which is transmitted to humans by mosquitoes, is common among pregnant women in sub-Saharan Africa and is a major contributing factor to low birth weights and infant deaths in that region. “The goal of this study,” Becker-Dreps said, “was to find out the costs and impact of giving bed nets to pregnant women in prenatal clinics, before their babies were born. The pregnant women could then use the bed nets during their pregnancies to reduce preterm deliveries and then use it to protect their young infants after birth.”

Questionnaires administered to the mothers found that 84 percent reported sleeping under the bed net every day or almost every day, six months after delivery. Interviewers who visited a sample of the mothers reported that 70 percent had their bed nets hanging in the correct position in their homes.

Becker-Dreps and colleagues combined this data with actual infant mortality and low birth weight data from clinics in the region and then performed statistical analyses that enabled them to produce their estimates. They concluded that bed net distribution is a cost-effective addition to prenatal services in the region.

Co-authors of the study, in addition to Becker-Dreps, Biddle and Behets, include Audrey Pettifor, Ph.D., Steven Meshnick, M.D., Ph.D., all from the Gillings School; and Gertrude Musuamba, M.D. from the School of Public Health in Kinshasa and David Nku Imbie, M.D., from the Salvation Army in Kinshasa.

Im Focus: Electron highway inside crystal

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.

Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...

Im Focus: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
