OBJECTIVE: Recent reports suggest persistence of health disparities related to socio-economic position (SEP). To understand if diet may be a contributor to these trends, we examined secular trends in the association of diet and indicators of SEP from 1971-1975 to 1999-2002. DESIGN: We used data from the National Health and Nutrition Examination Surveys (NHANES) I (1971-1975), II (1976-1980), III (1988-1994) and 1999-2002 to examine the independent associations of poverty income ratio (PIR) and education with diet and biomarkers of diet and disease in 25-74-year-olds (n = 36,600). We used logistic and linear regression methods to adjust for multiple covariates and survey design to examine these associations. RESULTS: A large PIR differential in the likelihood of reporting a fruit or all five food groups and vitamin C intake, and an education differential in likelihood of obesity and carbohydrate intake, was noted in 1971-1975 but narrowed in 1999-2002 (P < 0.007). The positive association of education with intake of a fruit, vegetable or all five food groups, vitamins A and C, calcium and potassium intake remained unchanged across surveys (P < 0.001). Similarly, the positive association of PIR with the amount of foods and intakes of energy and potassium remained unchanged over three decades (P < 0.001). The education and the PIR differential in energy density, and the PIR differential in the likelihood of obesity, persisted over the period of the four surveys (P < 0.001). CONCLUSIONS: Persistence of unfavourable dietary and biomarker profiles in Americans with low income and education suggests continued need for improvement in the quality of diets of these high-risk groups.<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-46651","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"Department of Family, Nutrition, and Exercise Sciences, Remsen Hall, Room 306E, Queens College of City University of New York, Flushing, NY 11367, USA. ashima.kant@qc.cuny.edu\r\n","annee":"2007","mois":"2","numero":"10:2","page":"158-67","auteurs":[{"ID":8954,"post_author":"0","post_date":"2018-12-03 18:05:47","post_date_gmt":"2018-12-03 17:05:47","post_content":"","post_title":"Ashima K Kant","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"ashima-k-kant","to_ping":"","pinged":"","post_modified":"2018-12-03 18:05:47","post_modified_gmt":"2018-12-03 17:05:47","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/ashima-k-kant\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":4156,"post_author":"0","post_date":"2018-12-03 17:12:58","post_date_gmt":"2018-12-03 16:12:58","post_content":"","post_title":"Barry I Graubard","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"barry-i-graubard","to_ping":"","pinged":"","post_modified":"2018-12-03 17:12:58","post_modified_gmt":"2018-12-03 16:12:58","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/barry-i-graubard\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"}],"sources":[{"ID":1299,"post_author":"0","post_date":"2018-12-03 15:58:08","post_date_gmt":"2018-12-03 14:58:08","post_content":"","post_title":"Public health nutrition","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"public-health-nutrition","to_ping":"","pinged":"","post_modified":"2018-12-03 15:58:08","post_modified_gmt":"2018-12-03 14:58:08","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/source\/public-health-nutrition\/","menu_order":0,"post_type":"source","post_mime_type":"","comment_count":"0","filter":"raw"}]},"yoast_head":"\n
