Malnutrition refers to deficiencies, excesses or imbalances in a person's intake of energy and/or nutrients. The burden of childhood malnutrition in developing countries continues to rise posing significant obstacle to achievement of better child health interventions. Several factors are involved in causation of malnutrition with Arid and Semi-Arid lands greatly affected as a result of erratic weather patterns, droughts, conflicts, poor access to health services and food among others. This study aims at investigating the risk factors for child malnutrition in North Rift Arid and semi-Arid lands (ASAL) counties of Kenya based on the 2014 Demographic and Health survey (DHS) data.
