Child Dietary Diversity and Associated Factors Among Children in Somalian IDP Camps.

BACKGROUND: Malnutrition and food insecurity are major challenges in Somalia, particularly among small children living in internally displaced person (IDP) camps. Poor diet has been identified as a key driver of malnutrition in young children who depend for their diets on their household's socioeconomic standing and access to food, as well as on the family's caring and feeding practices. OBJECTIVE: To assess the dietary diversity and identify the factors associated with it among children (6-23 months) in Somalian IDP camps. METHODS: We used a cross-sectional survey conducted in 11 IDP camps in Somalia in June 2014 and in June 2015. A total of 3188 children aged 6 to 23 months were surveyed. Child diets were assessed using food frequency questionnaires, and dietary diversity was categorized using the minimum child dietary diversity (MDDC) indicator. Multivariable logistic regressions were used to identify the factors associated with the children's dietary diversity. We built and compared 2 models using alternatively the household dietary diversity score (HDDS) and the food consumption score (FCS) as food security proxies. RESULTS: Around 15% of children in IDP camps reached the minimum dietary diversity. Overall, our results confirm that not only are food security proxies the factors most associated with MDDC, but HDDS performs better than FCS. In addition, results identify that women as key decision-maker in the household, duration of household permanence in the settlement, women's physiological status, frequency of milk feeding to child, type of toilet, and measles vaccination are positively associated with MDDC. CONCLUSIONS: To improve child dietary diversity in IDP camps, food security interventions should be broadened to include female empowerment and inclusive nutrition education (encouraging male participation) programs, as well as initiatives targeting children who do not live with pregnant or lactating women and that can support families beyond the first months after their arrival.

MUAC-for-age more useful than absolute MUAC for nutritional surveillance in Somalia: results from nineteen cross-sectional surveys (2007-2016).

BACKGROUND: Somalia is affected by a civil war and a protracted humanitarian crisis for more than two decades. The international community has put in place nutrition surveillance systems to monitor the situation and inform decisions. However, the indicators commonly used to identify acute malnutrition, weight-for-height Z-score (WHZ) and mid upper arm circumference (MUAC), do not always converge in their estimations of acute malnutrition, creating challenges for decision making. Furthermore, the divergences are not consistent across livelihood populations within the country. We explored the MUAC-for-age Z-score (MUACAZ) as an alternative indicator in Somalia to minimize the discrepancy. METHODS: We analyzed data from nineteen cross-sectional surveys conducted in Somalia between 2007 and 2016. We compared the acute malnutrition prevalence estimates by each of the indicators and the degree of overlap in the individual diagnosis of acute malnutrition between the WHZ and the MUAC-based indicators. We performed multivariate regression analysis with sex, age and stunting as independent variables and acute malnutrition as the dependent outcome, defined by WHZ, MUAC or MUACAZ. We performed all the analysis in the population overall and in each of the livelihood populations separately. RESULTS: A total 255,623 measurements of children 6-59 months of age were analyzed. The overall prevalence of global acute malnutrition by MUACAZ (15.8%) was similar to the one obtained using WHZ (16%), whereas prevalence based on MUAC was much lower (7.8%). These patterns of divergence were sustained throughout the nineteen surveys and the livelihoods studied, with only few exceptions. However, the proportion of overlap in the individual diagnosis of children as acutely malnourished was low between WHZ and absolute MUAC diagnosis (18.1%) and also between WHZ and MUACAZ (28.3%). Results show that age, sex and stunting status of the child affected the likelihood of being diagnosed as acutely malnourished to varying degrees, depending on the indicator used. CONCLUSIONS: The MUAC-for-age (MUACZ) indicator yielded acute malnutrition prevalence estimates convergent with those obtained by WHZ indicator. However, the degree of overlap between these two indicators for individual diagnosis of acute malnutrition is low. Further studies of MUACAZ as an alternative indicator for nutrition surveillance are needed.
