Children are at greater risk of malnutrition in Afghanistan than they are in many other countries. Malnutrition impairs the mental and physical growth of more than 50% of children in Afghanistan. It also exacerbates the risks of mortality by 45% in infants and children in Afghanistan. The purpose of this study was to determine the association between mothers' knowledge, attitudes, and practices regarding complementary feeding and malnutrition in children in Afghanistan. The precaution adoption process model served as a theoretical framework in this quantitative cross-sectional research study. Data analyzed were collected from 306 mothers and children at 6 randomly selected hospitals in Kabul Province. The results of logistic regression models indicated that mothers' knowledge, attitudes, and practices regarding complementary feeding were statistically significant predictors of stunting in children, Ï?2 (9, N = 306) = 45.33, p < .001; Ï?2 (9, N = 306) = 26.71, p < .01; and Ï?2 (9, N = 306) = 56.97, p < .001 respectively. The strongest predictor was mothers' practicing responsive feeding, where mothers who did not practice responsive feeding were 7.1 times more likely to have stunted children than mothers who practiced responsive feeding. Moreover, the results indicated that mothers' knowledge, attitudes, and practices of complementary feeding were statistically significant predictors of underweight in children, Ï?2 (9, N = 306) = 37.49, p < .001; Ï?2 (9, N = 306) = 41.15, p < .001; and Ï?2 (9, N = 306) = 44.64, p < .001. The implications for positive social change include reviewing nutrition policies, investing in nutrition programs, and operationalizing nutrition education and behavior change interventions for promoting appropriate complementary infant feeding practices in Afghanistan.

<p>Malnutrition and Anemia in children continue to be major public health challenges in most developing countries, particularly in Africa. Malnutrition and Anemia pervade all aspects of their health, growth, cognitive and social development. They lead to irreversible and lifelong effects that prevent children from realising their full potential. This study was designed to examine the prevalence and determinants of malnutrition and anemia in children under 5 years of age in the Ghanaian population. This research is based on data from the Ghana Demographic and Health Survey (GDHS) 2008, obtained from the Ghana Statistical Service (GSS). The survey is an extensive survey conducted using a stratified, two-stage cluster sampling design. The GDHS data contains a wealth of information on health, demographic, as well as socio-economic factors but is underutilised due to the complexity of the survey data. This study therefore stands out as one of the few that use the GDHS to investigate aspects of child health in Ghana. In this study, we perform subgroup analysis by disaggregating the data by age and gender specific subgroups and then by place of residence and region. This was in order to identify sub level estimates as national estimates have a high tendency of concealing true values and deviations from general trends. Also, subgroup analysis is very significant especially for resource allocation so as to minimize the likelihood of missing the target populations. We investigated associations between the three measurements of malnutrition; stunting, underweight and wasting and anemia (assessed by haemoglobin concentration) and the various risk factors using chi-square test to examine bivariate associations and chi-square trend test to examine linear trends in association. We identified the following variables to be significantly associated with all forms of malnutrition and/or anemia: age of child, mother’s education, financial status and place of residence. Other factors that were identified to be associated with some form of malnutrition and/or anemia include duration of breastfeeding, source of drinking water, mother’s occupation and currently breastfeeding. In view of the high rate of malnutrition, approximately 36% (33.6−37.6) and the alarming prevalence of anemia, 78% (76.7 − 80.2) in children in Ghana, particularly among those less than 2 years old, and the grave consequences on their cognitive and behavioral development even in later years, there is an urgent need for effective and efficient public health interventions.</p> / Master of Science (MSc)

<p dir="ltr">The spread and increasing prevalence of chronic wasting disease (CWD) in white-tailed deer (<i>Odocoileus virginianus</i>) has far reaching implications for natural resource management in Indiana. CWD is a transmissible spongiform encephalopathy that affects white-tailed deer and other cervids. This disease is invariably fatal in white-tailed deer, and there is concern that its continuing spread will cause populations to decline. White-tailed deer are also a culturally and economically important game species. Therefore, effective management of CWD must consider the epidemiologic, social, and economic dimensions of disease management. In Chapter One of my dissertation, I apply an agent-based model (ABM) framework to simulate how preemptive harvest increase and reactive culling affect CWD persistence and geographic spread. I found that preemptive harvest and reactive culling both had a small effect on preventing the establishment of CWD in the deer population. In Chapter Two, I test whether presenting deer hunters and non-deer hunters with results from CWD models and images of sick or healthy deer increases behavioral intention to engage in CWD mitigating behaviors. I found that using the web app did not change the behavioral intention of hunters and non-hunters. In Chapter Three, I conduct a cost-effectiveness analysis to identify the optimal combination of CWD surveillance and culling effort in terms of disease prevention. I found that testing 40% of hunter-harvested deer for CWD and culling 30% of deer within culling zones was most cost-effective in terms of disease prevention. In Chapter Four, I synthesize the results of the preceding chapters and discuss options for CWD management in Indiana.</p>
