Body composition patterns among normal glycemic, pre-diabetic, diabetic health Chinese adults in community: NAHSIT 2013-2016.

BackgroundCentral obesity is known to be associated with diabetes. Increasing lower extremity circumference was hypothesized in association with lower risk of diabetes.ObjectiveThis study determined which anthropometric patterns correlates the best with pre-diabetic and diabetic status among healthy adults.DesignCross-sectional study with nationwide population sampling of participants was designed.ParticipantsIn total, 1,358 ethnic Chinese adult participants were recruited from the Nutrition and Health Survey in Taiwan 2013-2016; the whole-body composition was measured through dual-energy X-ray absorptiometry.Main outcome measuresFat and lean mass in whole and specific parts of body among heathy Asian adults with normal glycemic, pre-diabetic, and diabetic states were measured, separately.Statistical analyses performedThe generalized linear model was used to investigate the association between body composition (lean and fat mass) and hyperglycemic status. The reduced rank regression (RRR) was used to confirm the correlation between glycemic status and predicting factors (body composition parameters).ResultsTrunk fat positively correlated with the fasting glucose level (r = 0.327, P ConclusionsFor healthy community participants, increasing trunk fat had a greater risk of hyperglycemic status. Increasing lower extremity mass may confer lower risk of diabetes
