IU study: Higher mercury levels in humans associated with increased risk for diabetes

08.04.2013
A new study found that higher levels of mercury exposure in young adults increased their risks for type 2 diabetes later in life by 65 percent. The study, led by Indiana University School of Public Health-Bloomington epidemiologist Ka He, is the first to establish the link between mercury and diabetes in humans.
The study paints a complicated nutritional picture because the main source of mercury in humans comes from the consumption of fish and shellfish, nearly all of which contain traces of mercury. Fish and shellfish also contain lean protein and other nutrients, such as magnesium and omega-3 polyunsaturated fatty acids, that make them important to a healthy diet.

In the study, published online early in the journal Diabetes Care, the people with the highest levels of mercury also appeared to have healthier lifestyles -- lower body mass indexes and smaller waist circumferences, more exercise -- than other study participants. They also ate more fish, which is a possible marker of healthy diet or higher social economic status. Risk factors for type 2 diabetes include being overweight.

The study, which involved 3,875 men and women, established the link between mercury levels and type 2 diabetes risk after controlling for lifestyle and other dietary factors such as magnesium and omega-3 polyunsaturated fatty acids, which could counter the effects of the mercury.

These findings, said He, point to the importance of selecting fish known to have low levels of mercury, such as shrimp, salmon and catfish, and avoiding fish with higher levels, such as swordfish and shark. FDA and EPA guidelines for fish consumption highlight this, particularly for women who are pregnant or of childbearing age and for young children.

"It is likely that the overall health impact of fish consumption may reflect the interactions of nutrients and contaminants in fish. Thus, studying any of these nutrients and contaminants such as mercury should consider confounding from other components in fish," He and the authors wrote in the study. "In the current study, the association between mercury exposure and diabetes incidence was substantially strengthened after controlling for intake of LCn-3PUFAs (omega-3) and magnesium."

The study participants were recruited from Birmingham, Ala., Oakland, Calif., Chicago and Minneapolis,and then followed for 18 years as part of the Coronary Artery Risk Development in Young Adults Study. He, chair of the Department of Epidemiology and Biostatistics in the IU School of Public Health-Bloomington, is principal investigator of the ancillary study, the CARDIA Trace Element Study, which is funded by the National Institutes of Health.

IU School of Public Health-Bloomington
With nearly 3,000 students in an array of undergraduate and advanced degree programs, the School of Public Health-Bloomington offers a traditional campus experience enriched by 21st-century innovation. More than 120 faculty in five academic departments -- Department of Kinesiology; Department of Applied Health Science; Department of Recreation, Park and Tourism Studies; Department of Environmental Health; and Department of Epidemiology and Biostatistics -- conduct major research, teach and engage with communities across a broad spectrum of health, wellness and disease-prevention topics. Each department offers numerous majors, minors and opportunities for graduate and undergraduate studies. In addition to its academic departments, the school administers Campus Recreational Sports, which serves roughly 80 percent of the IU Bloomington student body through various intramural, club and individual sports opportunities.

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...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
