Survival status of children treated for severe acute malnutrition in outpatient therapeutic program by season in Kembata Tembaro Zone, Southern Ethiopia Wondwosen Fikreselam1*, Samson Mideksa2 and Sintayehu Abate Temesgen3 1School of nutrition, food science and technology, Hawassa University, Hawassa, Ethiopia 2Knowledge Translation Directorate, Ethiopian Public Health Institute, Addis Ababa, Ethiopia 3Scientif and Ethical Review Office, Ethiopian Public Health Institute, Addis Ababa, Ethiopia *Corresponding author: [email protected] Abstract Background: Malnutrition is a deficiency state of both macro and micronutrients (under-nutrition) and their over consumption (over-nutrition) causing measurable adverse effects on human body structure and function, resulting in specific physical and clinical outcomes. Nearly 52 million under five children globally are malnourished, and in Africa it is about 14 million. However, there is little information known about seasonal variations of admission. Objective: To assess seasonal variations of admission of children treated for Severe Acute Malnutrition at Outpatient Therapeutic Program in Kembata Tembaro Zone, Southern Ethiopia. Methods: A retrospective facility based cross-sectional study was conducted from records of outpatient therapeutic program from January 01 to December 30, 2017. Four hundred thirty three children represented by their Outpatient Therapeutic Program card were included from three Woredas selected by simple random sampling technique. From these three Woredas, 18 health posts were selected by simple random sampling. Population Proportion to size allocation was used to assign sample for each selected Woredas. Systematic sampling technique was used to assign child card for each selected health posts in the study area. Data entered, cleaned and analyzed using SPSS version 20. Results: Seasonal distribution of Sever Acute Malnutrition admission to outpatient therapeutic program in Kembata Tembaro Zone shows 55.7% at 95% CI were admitted from December to May, 2017. Children survival rate through time was affected in statistically significant figures by distance from home to health posts <30 minutes (AHR=1.28; (95% CI=1.04-1.58)) Conclusions: Large extents of children were admitted to the program in dry season with climax admission at May. The survival rate was higher in wet season. The stakeholders should recognize as food insecurity can happen in dry season and focus on creating the capacity of the OTP providers on proper management of SAM.

Seasonal variations in Usually under nutrition is more common in developing temperature and rainfall can significantly impact countries (Alemu 2020). Although the prevalence may public health risks and disease incidence (Patz et al. differ, it is also found in developed countries (WHO 2000). In terms of food security, availability of food and UNICEF 2009). Severe acute malnutrition (SAM) decreases prior to harvest periods for agricultural is defined as a weight-for-height measurement of 70% producers and prior to rains for pastoralists. At the or more below the median, or three SD or more below same time, food prices rise due to limited availability the mean WHO reference values, which is called further impeding access for the majority of households “wasted,” the presence of bilateral pitting oedema of reliant on the market to cover at least some of their nutritional origin, which is called “edematous food needs. This period is commonly known as the malnutrition,” or a mid-upper-arm circumference of ‘lean’ season, or hunger period, when many less than 110 mm in children age 1–5 years (UNICEF households are teetering on the edge of food et al. 2018; Shanka et al. 2015). Under-nutrition and insecurity, and usually coincides with the rainy season, nutritional disorders are major problems, which are when disease strikes hardest. The end result is seasonal resulting from inadequate food intake both in quality peaks in acute malnutrition (Sullivan et al. 2013). In and quantity.

In this study, seasons were reclassified into two systematic random sampling technique. A total of 18 major categories: the dry season winter and autumn OTP sites were selected for the study. Finally, OTP (December to May) and the wet season summer and card of children aged 6-59 months were selected by spring (June to November) because they are believed systematic random sampling method from each HP to have an association with the nutritional status of based on their unique identification number.
