Magnesium consumption was evaluated using 24\u2009h dietary recalls.

We evaluated magnesium intake as a categorical variable (five quartiles). Compared with the lowest value, the highest multivariate adjusted odds ratio (95% confidence interval) for anemia was 0.64 (0.46\u20130.89). Stratified analyses revealed a reverse relationship between magnesium intake and anemia in women. However, no significant association was observed in men (<jats:italic>p<\/jats:italic><jats:sub>for trend<\/jats:sub>\u2009=\u20090.376).
