Prenatal Zinc Supplementation Could Impair Childhood Mental Development

26.07.2002


Authors of a study in this week’s issue of THE LANCET caution that the provision of zinc supplementation to pregnant women in developing countries could impair the early mental development of their children. Zinc deficiency is common in developing countries due to a diet that is low in animal protein and high in fibre. Supplements given to Bangladeshi pregnant women have previously been shown to improve infant growth and to reduce susceptibility to infectious diseases. In a follow-up study, Sally Grantham McGregor and Jena Habadani from the Institute for Child Health, London, UK, and colleagues from the International Center for Diarrhoeal Disease Research, Bangladesh, assessed these infants at 13 months of age to investigate the effect of antenatal zinc supplementation on infant development and behaviour.

The mental development of 168 infants (whose mothers received either 30 mg per day of zinc or placebo during pregnancy) were assessed. Infants in the placebo group had higher scores for both mental and psychomotor development. Zinc supplementation had no significant effect on behaviour or growth. The children’s nutritional status was poor—weight-for-age at testing was strongly related to development.

Sally Grantham McGregor comments: “Undernutrition is generally accepted to be detrimental to children’s development, our findings emphasise the serious nature of the problem in populations with high proportions of underweight children. Since zinc supplementation in infants has a beneficial effect on growth and morbidity, and supplementation of mothers was associated with reduced morbidity in low birthweight infants in this study, our findings complicate policy making…Undernourished pregnant women obviously require more than zinc alone. The next step would be to examine the effect of more comprehensive supplementations to improve maternal nutritional status during pregnancy on a broad range of outcomes including infants’ development.”

Im Focus: OLED microdisplays in data glasses for improved human-machine interaction

The Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP has been developing various applications for OLED microdisplays based on organic semiconductors. By integrating the capabilities of an image sensor directly into the microdisplay, eye movements can be recorded by the smart glasses and utilized for guidance and control functions, as one example. The new design will be debuted at Augmented World Expo Europe (AWE) in Berlin at Booth B25, October 18th – 19th.

Im Focus: Artificial Intelligence Helps in the Discovery of New Materials

With the help of artificial intelligence, chemists from the University of Basel in Switzerland have computed the characteristics of about two million crystals made up of four chemical elements. The researchers were able to identify 90 previously unknown thermodynamically stable crystals that can be regarded as new materials. They report on their findings in the scientific journal Physical Review Letters.

Im Focus: Complex hardmetal tools out of the 3D printer

For the first time, Fraunhofer IKTS shows additively manufactured hardmetal tools at WorldPM 2016 in Hamburg. Mechanical, chemical as well as a high heat resistance and extreme hardness are required from tools that are used in mechanical and automotive engineering or in plastics and building materials industry. Researchers at the Fraunhofer Institute for Ceramic Technologies and Systems IKTS in Dresden managed the production of complex hardmetal tools via 3D printing in a quality that are in no way inferior to conventionally produced high-performance tools.

Fraunhofer IKTS counts decades of proven expertise in the development of hardmetals. To date, reliable cutting, drilling, pressing and stamping tools made of...

Im Focus: Launch of New Industry Working Group for Process Control in Laser Material Processing

At AKL’16, the International Laser Technology Congress held in May this year, interest in the topic of process control was greater than expected. Appropriately, the event was also used to launch the Industry Working Group for Process Control in Laser Material Processing. The group provides a forum for representatives from industry and research to initiate pre-competitive projects and discuss issues such as standards, potential cost savings and feasibility.

In the age of industry 4.0, laser technology is firmly established within manufacturing. A wide variety of laser techniques – from USP ablation and additive...

Im Focus: New laser joining technologies at ‘K 2016’ trade fair

Every three years, the plastics industry gathers at K, the international trade fair for plastics and rubber in Düsseldorf. The Fraunhofer Institute for Laser Technology ILT will also be attending again and presenting many innovative technologies, such as for joining plastics and metals using ultrashort pulse lasers. From October 19 to 26, you can find the Fraunhofer ILT at the joint Fraunhofer booth SC01 in Hall 7.

K is the world’s largest trade fair for the plastics and rubber industry. As in previous years, the organizers are expecting 3,000 exhibitors and more than...
