Association between dietary fiber intake and total bone mineral density in adolescents: A cross-sectional analysis of the NHANES 2011-2018.

ABSTRACT: ObjectiveAdolescence is a critical window for optimizing peak bone mass. This study evaluated the independent association between dietary fiber intake and total body bone mineral density (BMD) in a representative sample of U.S. adolescents.MethodsThis cross-sectional study analyzed 2476 participants (aged 12-19 years) from the National Health and Nutrition Examination Survey 2011-2018. Dietary fiber intake was calculated as the average of two 24-h recalls. Total BMD was measured using dual-energy X-ray absorptiometry. Multivariable linear regression, generalized additive models, and stratified analyses were utilized, adjusting for sociodemographics, body mass index (BMI), physical activity, renal function markers (creatinine, blood urea nitrogen), and dietary variables (calcium, vitamin C,
