In low-and middle-income nations, the double burden of malnutrition is a rising problem. It is unusual for an underweight child and an overweight mother to exist together in the same household because they both occupy a shared environment and have access to the same dietary patterns and habits. The aim of this study was to investigate the predictors associated with double burden of malnutrition among the child-mother pairs living in Kericho County. The research design employed was cross-sectional descriptive study. The target population was 346 comprising of a child- mother pairs within the six sub-counties within Kericho County. The research employed the multi-stage stratified cluster sampling method to obtain the target households. A pre-tested questionnaire collected data from socioeconomic demographic characteristics, nutrition status for mother (Body Mass Index,) child (BMI- Z-scores), food consumption and frequency. Data processing was done using Ms Excel, SPSS vs. 26.0 and Nutri survey 2005 software. Categorical variables were analyzed, while measures of central tendencies and dispersion were computed.
