According to the 2018 SMART Nutrition and Mortality Survey conducted in Kaga, Jere, Konduga and Magumeri LGAs in Borno State, the prevalence of global acute malnutrition (GAM) was 15.7% (12.2-20.0, 95% C.I), with a severe acute malnutrition (SAM) prevalence of 4.2% (2.9-6.1, 95% C.I). The crude death rate was 0.79 deaths per 10,000 per day (0.52-1.20, 95% C.I), with an under 5 death rate of 1.60 deaths per 10,000 per day (0.83-3.07, 95% C.I). However, due to the persistent on-going conflicts in the areas, it is necessary to also continue monitoring the mortality trends, and as such, this survey will also measure the mortality rates. The overall objective of the survey was to determine the magnitude and severity of malnutrition and retrospective mortality rates amongst the population in the accessible communities of the 4 LGAs (Kaga, Jere, Konduga and Magumeri) in Borno State within the areas in which Save the Children is operational. Specific objectives To determine prevalence of Malnutrition (acute malnutrition, chronic malnutrition and underweight) among children 6-59 months in the target population in the accessible communities of the 4 LGAs. To assess retrospective morbidity among children under 5 in the target population in the 4 LGAs. To assess retrospective mortality (Crude Mortality and U5 Mortality rates) over 3 months’ recall period among target populations in the 4 LGAs. To estimate measles vaccination coverage of children 9-59 months and Vitamin A supplementation coverage of children 6-59 months in the target population in the 4 LGAs. To assess IYCF practices among the households with children under two years of age in the target population in the 4 LGAs. To estimate the prevalence of malnutrition in women of reproductive age (15-49 years) in the target population in the 4 LGAs. To establish recommendations on actions to address identified gaps, to support planning, advocacy, decision making and monitoring in the 4 LGAs. Methodology The Standardized Methodology for Assessment in Relief and Transitions (SMART) which applies a two-stage cluster sampling
