Introduction: Appropriate complementary feeding is an important determinant for achieving healthy growth and survival of infants and young children in the first years of life. Poorly managed, it increases the risk of undernutrition, illness and death in the latter. This study aimed to determine the proportion of minimum food intake in breastfed children and to identify the associated factors in the municipality.Methods: A cross-sectional, descriptive and analytical study of households was carried out in the commune of Kaolack (Senegal) from November 15 to 21, 2017. The multi-stage sampling method was used to select mothers of elderly breastfed children 6-23 months. The analysis was done using R software (version 3.4.3). Descriptive analyzes and simple logical regression were done. Odds ratios with a 95% confidence interval were used to identify the associated factors.Results: A total of 260 women were surveyed. Mothers of children represented 93.8% and the rest were babysitters. The mean age was 27.8 ± 6.6 years. In 94.6%, they were married and in 78.9% the mothers lived in a monogamous marriage. 71.5% of women were in school and 69.6% of mothers had more than two dependent children. Daily market spending was stable in 82.4% of households. The number of people living in the household was less than or equal to 10 people in 60.4% of the households.The sex ratio (M / F) of breastfed children was 1.34. The mean age of breastfed infants was 13.9 ± 4.5 months. Their average weight was 9.1 ± 1.5 kg. The mean height of the children was 75.7 ± 5.5 cm. Among the children surveyed, only 28.7% received a minimum acceptable intake in their diet. Regarding follow-up, 57.3% of women did not respect follow-up appointments promoting child growth.The factors associated with the low proportion of the minimum acceptable intake in children were: the status of the mother compared to babysitters (OR = 0.22 [0.06– 0.84]), the link of kinship with the head of household being a parent of the mother (OR = 2.87 [1.25 - 6.6]) compared to households headed by the father of the child, the regularity of daily expenses (7.41 [2.01– 27.37]) and compliance with the follow-up appointments promoting the child's growth (OR = 3.36 [1.73 - 6.51]).Conclusion: To ensure appropriate complementary feeding in children from 6 to 23 months, it is important to strengthen the socioeconomic level of households, sensitize mothers to respect the follow-up appointments promoting the growth of the child.
