OBJECTIVE: To determine whether nut intake is associated with the prevalence of metabolic syndrome in US adolescents.
DESIGN: A cross-sectional analysis of data from the National Health and Nutrition Examination Survey (NHANES) years 2003-2012. Anthropometric measurements, blood tests, 24 h diet recalls and demographic data were retrieved for participating adolescents. Metabolic syndrome was defined according to paediatric-modified Adult Treatment Panel III criteria. The exposure was defined as a nut intake≥5 g/d.
SUBJECTS: Individuals aged 12-19 years (n 2805).
RESULTS: Nut consumption was associated with lower odds for metabolic syndrome (crude OR=0·25; 95 % CI 0·11, 0·55; P≤0·001). This effect was independent of age, sex, race/ethnicity and family income:poverty ratio (adjusted OR=0·27; 95 % CI 0·12, 0·61; P=0·002), and was stable after controlling for nutritional covariates including intake of sugar and total energy consumption (OR=0·36; 95 % CI 0·16, 0·81; P=0·014).
CONCLUSION: Nut consumption of≥5 g/d is independently associated with lower odds for metabolic syndrome in US adolescents.
