Abstract: To determine the nutritional status of infants and infant feeding practices among low-income nursing mothers in Ondo State, S/W Nigeria. A cross-sectional survey was conducted among 800 infants (0-2 years) and their mothers (15-45 years). The subjects were randomly selected from rural and urban communities from the three senatorial district of the state. Trained interviewers used a questionnaire to collect information on the feeding patterns and types of weaning food. Anthropometrics measurement (weight and height) of the infants was measured. The results showed that the mean age (X±SEM) of the children was 13±0.41months and that of height and weight were 70.6±0.57 cm and 8.79±0.08 Kg, respectively. The age range of the nursing mothers was between the ages of 15 and 45 years and the mean value of children per mother was 2.48±0.08. The percentage of infant�s families falling within a high SES was 23.5%, medium SES was 28.4 and 48.1% was falling within low SES. The result of infant feeding pattern showed that 20.4% of nursing mothers breastfed their infants exclusively, 39.9% breastfed their child on demand and in addition to breast milk the children were also given herbal concoction in the morning and at night. Others, 37.7%, were timing when to breastfeed their babies and 2.0% of the mothers did not breastfed their infants. Introduction of weaning food result showed that 3.0% of the mothers introduced weaning foods to their children between the ages of 0-3 months, 33.5% introduced between 4-6 months and 43.1% introduced between 7-9 months. The common weaning food used was Ogi, traditionally made from cereal (corn or sorghum grains) by fermentation. The result of dietary intake of the children showed 20.4% were fed with breast milk only, 24.2% were fed with breast milk and ogi and 12.9% were fed with ogi only. Others, 10.9, 13.1, 14.1 and 4.4% were fed with breast milk plus infant formula, infant formula only, breast milk plus family diet and family diet (i.e., bread, yam, beans porridge, eba, amala etc.) only, respectively. The result of chemical analyses of ogi showed that MCP contained moisture content of 4.5 g, fat 4.3 g, carbohydrate 81.3 g, protein 6.4 g fiber 1.7 g and ash 1.8 g. The minerals and vitamins composition of MCP were calcium 74.6 mg, phosphorous 185.1 mg, iron 1.8 mg, thiamine 0.11 mg, riboflavin 0.09 mg and niacin 1.83 mg and that of SP were moisture content 7.1 mg, fat 6.7 mg, carbohydrate 72.6 mg, protein 8.7 mg, fiber 1.0 mg and ash 4.9 mg, others calcium 46.2 mg, phosphorus 244.1 mg, iron 3.3 mg, thiamine 0.5 mg, riboflavin 0.2 mg and niacin 3.4 mg. The classification of nutritional status showed that 63.0% of infants were falling with the normal categories and others, 22.5, 9.5 and 5.0% were classified as first, second and third degree of malnutrition, respectively. The results of this present study provide information on the nutritional status, breastfeeding patterns and main weaning food used among low-income nursing mothers in S/W Nigeria. It is not clear whether the findings are specific to the studied population alone or applicable to other parts of Nigeria. Further studies are needed to confirm these findings.
