Infant feeding practices in relation to iron status and other possible nutritional deficiencies in Pathumthani, Thailand.

Iron deficiency (ID) is the most common micronutrient deficiency worldwide and usually leads to impaired neurodevelopment. Appropriate introduction of complementary foods is mandatory for all infants to prevent iron insufficiency. We aimed to demonstrate feeding behaviors in relation to infant iron status and also identify potential concomitant nutrient inadequacies.A cross-sectional descriptive study of infants 6-12 months old was performed at the Well Baby Clinic at Thammasat University Hospital, Pathumthani. Demographic data, feeding practices and nutritional status were obtained. Dietary intake was evaluated using general and food frequency questionnaires. Blood samples for complete blood count and iron studies were investigated.We enrolled 206 infants (mean age 8.552.1 months). Prevalence of ID and iron deficiency anemia (IDA) was 34.0% and 25.7%, respectively. In multivariable ordinal continuation ratio logistic regression analysis for risk of iron depletion severity among the 3 groups (normal, ID and IDA infants), we found a stepwise increase in odds ratios for iron depletion with lower family income, longer duration of breastfeeding, delayed introduction of meat, and lower dietary iron intake. IDA infants had significantly lower intakes of energy, protein, fat and various micronutrients, compared to those with normal iron status.Infants with ID may have low intakes of other nutrients due to reduced complementary food intake. Nutritional education for appropriate feeding practices should be provided to prevent ID and other possible micronutrient deficiencies.
