The present paper reports the comparison of results on diet and GC risk obtained using the 2 types of controls. Population controls tended, in general, to eat all kinds of foods slightly more frequently (bread, pasta, cold cuts, fresh fish, seasoned cheeses, legumes, garlic, onions and preserved fruits), with the exception of cooked vegetables, which were reported less frequently by population than by hospital controls. ORs for specific foods adjusted for confounders and other foods were consistent in the separate models including population and hospital controls respectively for all food groups, with the exception of cooked vegetables which represented a protective factor only when hospital controls were considered (high consumers, population controls: adjusted, OR=0.9, trend p value 0.54; high consumers, hospital controls, adjusted OR=0.5, trend p value <0.01). Hospital controls were slightly less often current smokers (22.6 versus 30.0%) and more often regular wine drinkers (57.5 versus 47.8%) compared with population controls, but none of these variables was associated with GC risk. The main results in this study were consistent using both types of controls, nevertheless the distribution of some dietary variables not related to the disease under study differed between the 2 control groups, suggesting some caution in the use of hospital controls when studying diseases other than GC. © European Journal of Public Health ORIGINAL ARTICLES nationallicence selection controls nationallicence case control study nationallicence AMADORI DINO Divisione di Oncologia Medica Forli, Itaty aut NANNI ORIANA Istituto Oncologico Romagnolo Forfl, Italy aut RICCI MIRANDA Istituto Oncologico Romagnolo Forfl, Italy aut FALCINI FABIO Divisione di Oncologia Medica Forli, Itaty aut DECARLI ADRIANO Istituto dl Statistica Medica e Blometria, Universita dl Milano Milan, Italy aut PALLI DOMENICO Unità di Epidemiologia, Centro per lo Studio e la Prevenzione Oncologka Florence, Italy aut BUIATTI EVA Unità di Epidemiologia, Centro per lo Studio e la Prevenzione Oncologka Florence, Italy aut The European Journal of Public Health Oxford University Press 5/3(1995), 209-214 1101-1262 5:3<209 1995 5 eurpub https://doi.org/10.1093/eurpub/5.3.209 text/html Onlinezugriff via DOI 1 research-article jats NATIONALLICENCE 856 40 https://doi.org/10.1093/eurpub/5.3.209 text/html Onlinezugriff via DOI NATIONALLICENCE 700 1- AMADORI DINO Divisione di Oncologia Medica Forli, Itaty aut NATIONALLICENCE 700 1- NANNI ORIANA Istituto Oncologico Romagnolo Forfl, Italy aut NATIONALLICENCE 700 1- RICCI MIRANDA Istituto Oncologico Romagnolo Forfl, Italy aut NATIONALLICENCE 700 1- FALCINI FABIO Divisione di Oncologia Medica Forli, Itaty aut NATIONALLICENCE 700 1- DECARLI ADRIANO Istituto dl Statistica Medica e Blometria, Universita dl Milano Milan, Italy aut NATIONALLICENCE 700 1- PALLI DOMENICO Unità di Epidemiologia, Centro per lo Studio e la Prevenzione Oncologka Florence, Italy aut NATIONALLICENCE 700 1- BUIATTI EVA Unità di Epidemiologia, Centro per lo Studio e la Prevenzione Oncologka Florence, Italy aut NATIONALLICENCE 773 0- The European Journal of Public Health Oxford University Press 5/3(1995), 209-214 1101-1262 5:3<209 1995 5 eurpub Metadata rights reserved CC BY-NC-4.0 http://creativecommons.org/licenses/by-nc/4.0 nationallicence BK010053 XK010053 XK010000 NATIONALLICENCE NATIONALLICENCE NL-oxford
