Does diet mediate associations of volume and bouts of sedentary time with cardiometabolic health indicators in adolescents?

ABSTRACT:

Objective

Examine the mediating role of diet in the relationship between volume and duration of sedentary time with cardiometabolic health in adolescents.

Methods

Adolescents (12-19 years) participating in the 2003/04 and 2005/06 U.S. National Health and Nutrition Examination Survey (NHANES) were examined. Cardiometabolic health indicators were body mass index z-scores (zBMI) (n = 1,797) and metabolic syndrome (MetS) (n = 812). An ActiGraph hip-worn accelerometer was used to derive total sedentary time and usual sedentary bout duration. Dietary intake was assessed using two 24-hour dietary recalls. Mediation analyses were conducted to examine five dietary mediators [total energy intake, discretionary foods, sugar-sweetened beverages (SSB), fruits and vegetables, and dietary
