The hypothesis of vitamin A intake deficiencies serving as an antecedent factor in the development of stomach cancer was assessed employing a case-control design. Interviews of proxy informants for 111 cases and a pair-matched control group were conducted using a food frequency questionnaire from which an averaged vitamin A intake index was calculated. Stomach cancer cases showed a significantly higher proportion with lowered total vitamin A intake levels (odds ratio = 1.71) which remained constant across sex and socioeconomic status groupings. These results demonstrated a consistency with previous related studies vis-à-vis the strength and specificity of the putative association, a moderate (but statistically nonsignificant) dose-response curve, proper temporal association, and biologic plausibility.
