Shi Z and Badi Abou-Samra A – In this cross-sectional study, researchers explored the connection between serum magnesium and diabetes and hypertension among Qatari adults. Data were used from 9,693 Qatari participants (aged ≥ 20 years) from the Qatar Biobank (QBB) Study. Using serum magnesium as a response variable, reduced rank regression was used to construct magnesium related dietary pattern (MRDP). According to findings, the prevalence for diabetes, prediabetes, and subclinical magnesium deficiency was 18.9%, 11.5%, and 59.5%, respectively. The prevalence ratios for diabetes were 1.00, 1.35, 1.88, and 2.70, respectively, across the quartiles of serum magnesium from high to low. Overall, subclinical magnesium deficiency was found to be common in Qatar and, in Qatari adults, is linked to diabetes, prediabetes, and hypertension. In addition, a low intake of MRDP was positively related to diabetes and high HbA1c.
