Abstract
This study evaluated the role of social inequalities in complementary feeding patterns between and within countries in Latin America and the Caribbean. This ecological study employed aggregate data from population-based surveys. The units of analysis were all 16 countries in Latin America and the Caribbean for which information was available in the Demographic and Health Surveys (DHS) and Multiple Indicator Cluster Surveys (MICS) databases. The outcomes selected were the prevalences indicated by the “introduction of solid, semi-solid or soft foods” (ISSSF), “minimum dietary diversity” (MDD), “minimum meal frequency” (MMF) and “minimum acceptable diet” (MAD) standardised complementary feeding indicators recommended by the WHO and available in UNICEF databases. The differences in prevalences between the wealthiest and poorest income quintiles were calculated in absolute and relative terms. Comparing the four indicators of complementary feeding, the ISSSF showed best performance, returning prevalence above 80% in 10 of the 11 countries evaluated. The indicator showing worst performance was the MAD, with prevalence above 60% in only one of the eight countries evaluated. In almost all countries, by all indicators, prevalences of complementary feeding were lower in the poorest population groups than in the wealthiest.
