Plasma fatty acids in de novo lipogenesis pathway are associated with diabetogenic indicators among adults: NHANES 2003-2004.

Background: Insulin regulates fatty acids (FAs) in the blood; conversely, FAs may mediate insulin sensitivity and are potentially modifiable risk factors of the diabetogenic state.

Objective: The objective of our study was to examine the associations between plasma concentrations of FAs, fasting plasma glucose (FPG), and glycated hemoglobin (HbA1c) among individuals (n = 1433) in the NHANES (2003-2004).

Design: Plasma concentrations of 24 individual FAs were considered individually and in subgroups, per chemical structure.

Associations of dietary, lifestyle, and sociodemographic factors with iron status in Chinese adults: a cross-sectional study in the China Health and Nutrition Survey.

Background: Although a high prevalence of anemia and related disease burden have been documented in China, limited evidence is available on the current population-level iron status and risk factors for iron imbalance.

Objective: We explored the associations of dietary, lifestyle, and sociodemographic factors with iron status in Chinese adults.

Design: Our study population consisted of 7672 adults aged 18-65 y from the 2009 China Health and Nutrition Survey.
