THURSDAY, April 23, 2020 (HealthDay News) — Higher intake of manganese is associated with a lower type 2 diabetes risk among postmenopausal women, independent of known risk factors, according to a study published online April 15 in Diabetes Care<\/i>.<\/p>\n
Jung Ho Gong, from Brown University in Providence, Rhode Island, and colleagues evaluated the association between manganese intake and the risk for type 2 diabetes in 84,285 postmenopausal women without a history of diabetes participating in the national Women’s Health Initiative Observational Study (WHI-OS). Results were validated in the 62,338 women who participated in the WHI-Clinical Trial (WHI-CT).<\/p>\n
The researchers found that compared with the lowest quintile of energy-adjusted dietary manganese, WHI-OS participants in the highest quintile had a lower risk for type 2 diabetes (hazard ratio, 0.70). These findings were confirmed in the WHI-CT (hazard ratio, 0.79). In a nested case-control study of 3,749 women in the WHI-OS with information on biomarkers of inflammation and endothelial dysfunction, higher energy-adjusted dietary manganese was associated with lower circulating levels of inflammatory biomarkers that significantly mediated the association between dietary manganese and type 2 diabetes risk. Of type 2 diabetes risk due to manganese, 19 percent of risk was mediated through interleukin 6 and 12 percent through high-sensitivity C-reactive protein.<\/p>\n
“Consumption of food groups rich in manganese could potentially be targets for intervention against type 2 diabetes risk in postmenopausal women,” the authors write.<\/p>\n
