Résumé
Background/objectives
While the association between food quantity and obesity is well studied, the impact of diet components on specific body compartments is less well understood. Furthermore, there seem to be sex differences in the metabolism of different foods and the response towards physical activity (PA).
Methods
We investigated the association between diet components using a food frequency questionnaire, and body composition using bioimpedance analysis. We assessed data from 2021 of a cohort study of the Swiss general population, including 435 persons of both sexes (age range of 19-84 years). We used multivariable linear regression models separated by sex to assess the association between body composition (body mass index (BMI), skeletal muscle mass index (SMI), fat mass index (FMI), and visceral fat (VAT)), and diet quality and PA. Age, education, and place of residence were included as potential confounders.
