Dietary n-3 Fatty Acids Intake and All-Cause and Cardiovascular Mortality in Patients With Prediabetes and Diabetes.

Context: While the association between n-3 polyunsaturated fatty acids (PUFAs) and cardiovascular (CV) events has been thoroughly examined, there is still a scarcity of research regarding their effect on the long-term prognosis in diabetic patients.

Objective: We aimed to explore the effects of n-3 PUFA on all-cause and cardiovascular mortality in patients with pre-diabetes and diabetes.

Method: Herein, a total of 16 539 eligible individuals were enrolled from the National Health and Nutrition Examination Survey (NHANES) 2003 to 2018, and categorized into T1, T2, and T3 based on the tertiles of n-3 PUFA.

Relationship between serum 25-hydroxyvitamin D concentrations and blood pressure among US adults without a previous diagnosis of hypertension: evidence from NHANES 2005-2018.

Background: There are various cross-sectional studies that concluded that vitamin D is associated with blood pressure, but randomized controlled studies have not yielded consistent conclusions. Considering many limitations indeed, our study aimed to examine whether concentrations of 25(OH)D are inversely associated with blood pressure in people without a previous diagnosis of hypertension.

Method: We analyzed data from the 2005-2018 National Health and Nutrition Examination Survey.
