Prior studies have demonstrated that paradoxically, women living in food insecure households report higher rates of overweight and related health complications. “The present study was conducted to estimate the association between household food insecurity status and maternal health during pregnancy, when changes in both body weight and overall health can be dramatic,” according to Barbara A. Laraia, PhD, MPH, RD, and co-investigators.
“The results suggest that the experience of living in a food insecure household was associated with metabolic health indicators during pregnancy. Not only was living in a food insecure household associated with severe pregravid obesity—a condition that broadly predisposes women to adverse pregnancy outcomes—but also with greater gestational weight gain and gestational diabetes mellitus.”
Researchers from the University of North Carolina, Chapel Hill, and the US Department of Agriculture’s Economic Research Service, Washington, DC, used data from the Pregnancy, Infection and Nutrition prospective cohort study—810 pregnant women with incomes less than 400% of the income/poverty ratio were followed through their pregnancies. This household income restriction allowed better comparison among households that might have food insecurity due to financial and material constraints. In this group, 76% were from fully food secure, 14% were from marginally food secure, and 10% were from food insecure households.
A significant finding that emerged is the association between household food insecurity and development of GDM. The authors observed that the combined group of women from marginally secure and insecure food households had more than twice the odds of developing GDM than women in food secure households, suggesting that women living in a household with any level of food insecurity may be at risk. This is an important public health finding given that GDM has implications for both the fetus (macrosomia or excessive birth weight) as well as the mother (a significant precursor to type II diabetes later in life).
Overall, women from marginally food secure and food insecure households were similar with regard to most demographic, socioeconomic and weight status variables assessed in this study. Compared to women from food secure households, women from marginally secure and food insecure households were significantly more likely to be black, to be single, have fewer years of education, less income and be either overweight or severely obese.
The authors recommend continuation of public health efforts to provide adequate funding and outreach to those in need and advocate population-based programs and policies designed to ensure that pregnant women have access to high-quality, nutritious food.

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.
The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...

There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
