Shi Z, et al. - 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 candidates (aged 20 years and above) attending 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 results, The prevalence was 18.9%, 11.5% and 59.5% for diabetes, prediabetes and subclinical magnesium deficiency, 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, the authors concluded that subclinical magnesium deficiency is 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.
