Résumé :	Background: Most previous studies have examined the associations between carotenoids and anthropometrics with cross-sectional designs. Few studies have investigated the associations between serum carotenoids and fat mass and fat distribution (general vs central type). Objective: This study aimed to explore the associations of serum carotenoids with body fat and fat distribution in Chinese adults. Design: Cross-sectional and longitudinal analyses of a prospective, community-based cohort were performed. Participants/setting: There were 4,048 participants aged 40 to 75 years recruited in the Guangzhou Nutrition and Health Study from 2008 to 2013. Main Outcome Measures: Serum carotenoids were assessed at baseline. Anthropometrics, fat mass (FM), and percentage FM (%FM) over the total body, trunk, limbs, and android and gynoid regions were obtained by dual-energy x-ray absorptiometry for 3,002 participants between 2011 and 2013 and for 2,537 participants after 3.1 years. Statistical Analysis: Cross-sectional and longitudinal analyses were performed to compare the mean differences in adiposity indices among the quartiles of carotenoids. Results: Covariance analyses showed significant inverse associations between serum total carotenoid levels and adiposity indices cross-sectionally (all P trends Conclusions: Serum carotenoid concentrations are inversely associated with body fat, especially in the abdominal region, in Chinese adults.
