Diet was assessed twice during follow-up by using a food-frequency questionnaire. RESULTS: During follow-up, 438 incidents of ovulatory infertility were reported. In logistic regression analyses, intakes of total fat, cholesterol, and most types of fatty acids were not related to ovulatory infertility. Each 2% increase in the intake of energy from trans unsaturated fats, as opposed to that from carbohydrates, was associated with a 73% greater risk of ovulatory infertility after adjustment for known and suspected risk factors for this condition [relative risk (RR) = 1.73; 95% CI: 1.09, 2.73]. Obtaining 2% of energy intake from trans fats rather than from n-6 polyunsaturated fats was associated with a similar increase in the risk of ovulatory infertility (RR = 1.79; 95% CI: 1.11, 2.89). In addition, obtaining 2% of energy from trans fats rather than from monounsaturated fats was associated with a more than doubled risk of ovulatory infertility (RR = 2.31; 95% CI: 1.09, 4.87). CONCLUSION: trans Unsaturated fats may increase the risk of ovulatory infertility when consumed instead of carbohydrates or unsaturated fats commonly found in nonhydrogenated vegetable oils.<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-47193","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"Department of Nutrition, Brigham and Women's Hospital, Harvard Medical School, Boston, MA 02115, USA. \r\n\r\njchavarr@hsph.harvard.edu","annee":"2007","mois":"1","numero":"85-1","page":"231-7","auteurs":[{"ID":1412,"post_author":"0","post_date":"2018-12-03 15:59:08","post_date_gmt":"2018-12-03 14:59:08","post_content":"","post_title":"Walter C Willett","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"walter-c-willett","to_ping":"","pinged":"","post_modified":"2018-12-03 15:59:08","post_modified_gmt":"2018-12-03 14:59:08","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/walter-c-willett\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":4185,"post_author":"0","post_date":"2018-12-03 17:13:14","post_date_gmt":"2018-12-03 16:13:14","post_content":"","post_title":"Bernard A Rosner","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"bernard-a-rosner","to_ping":"","pinged":"","post_modified":"2018-12-03 17:13:14","post_modified_gmt":"2018-12-03 16:13:14","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/bernard-a-rosner\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":7824,"post_author":"0","post_date":"2018-12-03 17:53:17","post_date_gmt":"2018-12-03 16:53:17","post_content":"","post_title":"J E Chavarro","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"j-e-chavarro","to_ping":"","pinged":"","post_modified":"2018-12-03 17:53:17","post_modified_gmt":"2018-12-03 16:53:17","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/j-e-chavarro\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":34150,"post_author":"0","post_date":"2018-12-04 00:23:43","post_date_gmt":"2018-12-03 23:23:43","post_content":"","post_title":"Jw Rich-edwards","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"jw-rich-edwards","to_ping":"","pinged":"","post_modified":"2018-12-04 00:23:43","post_modified_gmt":"2018-12-03 23:23:43","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/jw-rich-edwards\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"}],"sources":[{"ID":1720,"post_author":"0","post_date":"2018-12-03 16:01:56","post_date_gmt":"2018-12-03 15:01:56","post_content":"","post_title":"Am J Clin Nutr.","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"am-j-clin-nutr","to_ping":"","pinged":"","post_modified":"2018-12-03 16:01:56","post_modified_gmt":"2018-12-03 15:01:56","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/source\/am-j-clin-nutr\/","menu_order":0,"post_type":"source","post_mime_type":"","comment_count":"0","filter":"raw"}]},"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v23.6 (Yoast SEO v23.6) -
