We studied the prevalence of food sensitization in Ghanaian schoolchildren.<\/p>\n<p>METHODS: Children (5-16 years; n = 1,714) from 9 Ghanaian schools were given parental consent to participate in the study. Adverse reactions and food consumption were determined by a questionnaire and atopy by skin prick testing (SPT) to peanut and 6 fruits. Subjects with positive SPTs were considered cases (n = 43) and matched with at least 1 control (n = 84), using age, sex, and school as matching criteria. Serum samples from case-control sets were analyzed for specific IgE (sIgE) to foods that elicited a positive SPT response in cases.<\/p>\n<p>RESULTS: Overall, 11% of 1,407 children reported adverse reactions to foods, and 5% of 1,431 children showed a positive SPT reaction mostly directed against peanut and pineapple (both 2%). Although there was a positive association between adverse reactions and SPT responses to any food allergen in the urban children (adjusted OR = 3.6, 95% CI 1.2-10.8), most of the reported adverse reactions were not in children showing an SPT reaction to the specific food item. sIgE sensitization was very variable for the different foods, ranging from 0 to 100% in cases, and from 0 to 25% among controls. High IgE levels for a food item significantly increased the risk of SPT positivity to any food item in the urban, but not in the rural, schoolchildren.<\/p>\n<p>CONCLUSIONS: Specific foods were identified to be allergenic in Ghana. We show a good association between SPT and sIgE in urban, but not in rural, schoolchildren. However, there was no clear association between reported adverse reactions to food and SPT or sIgE<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-38960","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"Department of Parasitology, Leiden University Medical Centre, The Netherlands","annee":"2011","mois":"0","numero":"","page":"","auteurs":[{"ID":38956,"post_author":"0","post_date":"2018-12-04 01:45:46","post_date_gmt":"2018-12-04 00:45:46","post_content":"","post_title":"Amoah","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"amoah","to_ping":"","pinged":"","post_modified":"2018-12-04 01:45:46","post_modified_gmt":"2018-12-04 00:45:46","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/amoah\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":38957,"post_author":"0","post_date":"2018-12-04 01:45:47","post_date_gmt":"2018-12-04 00:45:47","post_content":"","post_title":"Yazdanbakhsh","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"yazdanbakhsh","to_ping":"","pinged":"","post_modified":"2018-12-04 01:45:47","post_modified_gmt":"2018-12-04 00:45:47","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/yazdanbakhsh\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":38958,"post_author":"0","post_date":"2018-12-04 01:45:47","post_date_gmt":"2018-12-04 00:45:47","post_content":"","post_title":"Obeng","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"obeng","to_ping":"","pinged":"","post_modified":"2018-12-04 01:45:47","post_modified_gmt":"2018-12-04 00:45:47","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/obeng\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"}],"sources":[{"ID":38959,"post_author":"0","post_date":"2018-12-04 01:45:48","post_date_gmt":"2018-12-04 00:45:48","post_content":"","post_title":"INT ARCH ALLERGY IMMUNOL","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"int-arch-allergy-immunol","to_ping":"","pinged":"","post_modified":"2018-12-04 01:45:48","post_modified_gmt":"2018-12-04 00:45:48","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/source\/int-arch-allergy-immunol\/","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) -
