Dietary fructose intake is correlated with fat distribution in the Newfoundland population.

Abstract

OBJECTIVE\nIncreased dietary fructose intake is associated with elevated body weight and body mass index. Few studies are available regarding the relationship between fat distribution and dietary fructose intake. The aim of this study was to investigate the association between dietary fructose intake and fat distribution in adults in a large Newfoundland cohort.\n\n\nMETHODS\nWe analyzed 2298 adults from CODING (Complex Diseases in the New found land Population: Environment and Genetics) study. Intake of dietary fructose was evaluated from the Willett food frequency questionnaire. Fat distribution was estimated by dual-energy x-ray absorptiometry. Partial correlation analysis was used to determine the correlations of dietary fructose intake with fat distribution adjusted for major confounding factors.\n\n\nRESULTS\nDaily dietary fructose intake was negatively associated with arm fat in postmenopausal women (r\xa0=\xa0-0.080, P < 0.05), but positively associated with arm fat in premenopausal women after adjusting for age, total calorie intake, and physical activity levels (r\xa0=\xa00.079, P < 0.05). Dietary fructose intake was negatively correlated with both arm fat (r\xa0=\xa0-0.131, P < 0.05) and visceral fat (r\xa0=\xa0-0.124 measured in mass, r\xa0=\xa0-0.124 measured in volume respectively; P < 0.05) in men <45 y of age, not in men ≥45 y.\n\n\nCONCLUSION\nThis study demonstrated that dietary fructose intake is significantly correlated with arm fat in both women and men, and visceral fat in men in the Newfoundland free-living population. The correlations are sex- and menopause-status dependent.
