Maternal Perceptions and Feeding Practices Associated with Infant Nutritional Status.

Introduction: Malnutrition in early childhood has long-term health consequences, including increased obesity risk due to catch-up growth in undernourished infants. While maternal perceptions and feeding practices affect infant malnutrition, limited evidence exists in middle-income countries like Mexico. This study examines the associations between maternal perceptions, feeding practices, and nutritional status in infants aged 6-12 months in northeastern Mexico.

Methods: A total of 192 mother-infant dyads were assed using questionnaires and anthropometric measurements. Maternal variables included perception of hunger and satiety, infant weight perception, feeding attitudes, self-efficacy, fatigue, and feeding practices. Infant nutritional status was determined using WHO Anthro, and multiple logistic regression identified associations between maternal and infant factors and nutritional status.

Results: 38% of infants were overweight/obese, and 7% were underweight. Low maternal self-efficacy, low perception of hunger and satiety signs, non-recommended feeding attitudes, and inaccurate perception of infant weight were identified. Maternal nocturnal sleep hours, type of feeding, and feeding frequency were associated to underweight. The maternal perception of infant weight was inaccurate for both underweight (mothers overestimate the weight) and overweight/obese (mothers underestimate the weight) infants.

Discussion: The main maternal perception influencing infant nutritional status was inaccurate weight perception. Mothers demonstrated limited knowledge and negative feeding practices with non-recommended feeding practices among Mexican mothers. Longer maternal sleep duration (> 8 h/night) was associated with underweight infants.
