The effect of schooling on nutritional knowledge, attitudes and nutritional outcomes in Ethiopia was investigated. Data were obtained in late 1989 in Debre Birhan in Shoa province from three groups: 267 mothers, 114 clinic users and six primary schools with a total of 528 students. Mothers and students were administered tests measuring nutritional knowledge and attitudes. The nutritional status of children age 6-31 months was evaluated by measurement of the weight and height. Schooling, particularly upper secondary schooling, was found significantly influence nutritional knowledge and nutritional outcomes. A causal model is presented which suggests that modern nutritional knowledge, together with the educational level of the mother, is immensely important in influencing nutritional practices. The study suggests that while schooling influences nutritional knowledge and nutritional outcomes, greater attention must be given to improving instruction in nutrition at the primary and lower secondary level.

Soybean is emerging as a very important food, market and oil crop in Ethiopia. However, its productivity in Western Ethiopia is constrained by several production constraints, of which soil acidity is one of the most important ones. On acidic soils the availability of several plant nutrients is limited; among which phosphorus is the least available. Thus, development of high yielding and low P tolerant soybean varieties need to be among the top priorities in areas with such problematic soils. Therefore, the objectives of the study were to: 1) conduct a Participatory Rural Appraisal (PRA) study to assess farmers’ perception on various soil fertility, soybean consumption and marketing issues, 2) evaluate soybean genotypes under low and high P regimes, and 3) conduct genetic analysis of soybean performance under low and high P conditions. The PRA was conducted to assess farmers’ perception on various soil fertility, soybean consumptions and market issues. A total of 186 soybean producing farmers across three locations of Western Ethiopia were interviewed using a semi-structured questionnaire. Results from the study indicated that the use of soybean for crop rotation and soil fertility improvement was more important to the farmers than household consumption and marketing of the crop. The study also revealed poor demand for soybean compared to other crops on the local market. The majority of respondent farmers’ recognized that soil fertility has been declining over time and obtaining inorganic fertilizers on time was difficult; mainly due to high price of fertilizer. Though farmers’ cooperative was identified as the major supplier of fertilizer, farmers rated the quality of its service in supplying fertilizer as poor. With deteriorating soil fertility and limited capacity to use inorganic fertilizers, farmers are producing soybean under low soil fertility conditions. Thus, breeding programs need to develop varieties that perform well under low fertility soil. Screening soybean genotypes for response to different P regimes was performed in a field experiment using a split plot design, where the main plots were three levels of applied P (0, 100 and 200 kg ha-1 P), and the sub plots were 36 soybean genotypes (G) planted across three locations (L) with two replications. The extent of genetic variation of the 36 soybean genotypes was assessed under low (0 kg ha-1) and high P (100 kg ha-1) conditions. The analysis of variance revealed significant differences among genotypes for all the traits, except pod number at low P; while all the traits, except root volume, pod number, and number of seeds per pod showed significant differences at high P. Plant fresh weight, root fresh weight and root volume exhibited high genotypic coefficient of variation (GCV) and phenotypic coefficient of variation (PCV) under both P conditions. Both principal component and cluster analyses revealed variation in the population. The 100-seed weight, plant height, roots and plant fresh weight combined high heritability and genetic advance estimates indicating that the inheritance of such traits is controlled by additive gene action under both P conditions. In general, the study revealed high genetic variation in the population, which can be exploited to improve performance under both high and low P conditions. The analysis of variance revealed significant genotype X phosphorus (GXP) interaction for number of nodules and total nodule weight at Jimma, and Assossa, and for root weight and root volume at Mettu. Though the GXP and GXPXL interactions showed non-significant difference for across locations analysis, the genotypes displayed significant difference for root fresh weight, root volume, tap root length, and weight of effective nodule. Genotypes: Pr-142 (26), AGS-3-1, SCS-1, AGS 234, and H 3 were identified among the best for root and nodulation characteristics. Yield and yield related traits were also assessed separately in the screening program. The results revealed significant GXP interactions for grain yield only at one site; while the genotypes exhibited highly significant differences for most of the traits in all the sites. G and GXL interaction were significantly different for most the traits. Essex 1, IAC 11, and AGS-3-1 were the best performing genotypes at high P; while genotypes IAC 11, AA 7138, G 9945 and AGS-7-1 displayed tolerance to low P. Genotypes AA-7138, PR-142 (26) and H3 exhibited stable performance across the three P levels. These genotypes have paramount significance in breeding soybean for low P tolerance and stable performance in varying P conditions for resource poor subsistence farmers.The genetic control mechanism for the major quantitative traits for performance under high and low P condition was studied in a nine parent half diallel cross. The results revealed that the GCA effects were highly significant for grain yield, pod length, days to maturity and plant height under low-P conditions. GCA effects were highly significant for grain yield, 100-seed weight, days to maturity, plant height, pod number, and pod length under high P. GCA effects were also significant for number of seeds per pod under high P condition. In addition, the relative contribution of GCA was higher than SCA under both P conditions, except for 100-seed weight at low P. Variety Hardee-1 was the best general combiner for most of the quantitative traits under both P conditions, indicating that it can be used in breeding programs to improve soybean for better genetic response to low and high P. / Thesis (Ph.D.)-University of KwaZulu-Natal, Pietermaritzburg, 2012.

Background: The health benefits and economic gains of exclusive breastfeeding for the mothers and the new-born are well-documented in the literature as discussed in the background and the rationale for this study. The effectiveness of the social cognitive based interventions in promoting breastfeeding among women in general is also documented. However, there is lack of evidence regarding social-cognitive strategies that could be used to promote exclusive breastfeeding practices among primiparous mothers in Ethiopia means that current exclusive breastfeeding promotion interventions or strategies may not produce the expected outcomes. This assumption seems to be supported by low rate of early initiation of breastfeeding in country (52.1% instead of at least 75% as recommended by WHO) and shorter period of breastfeeding (one month) among mothers in Addis Ababa (CSA and ICF 2012) despite various strategies and interventions that have been implemented. Aims: The study was conducted with the aim of determining the social-cognitive predictors of exclusive breastfeeding among primiparous mothers during the first six months post-delivery with the view of developing social-cognitive strategies to promote exclusive breastfeeding practices among primiparous mothers in Addis Ababa, Ethiopia. Research design and method: The study was carried out within the quantitative positivist paradigm. The study was divided into two phases. The researcher used quantitative longitudinal, descriptive, exploratory and correlational designs to determine the social cognitive predictors of exclusive breastfeeding among primiparous mothers in Addis Ababa, Ethiopia within the first six months post-delivery. The results of the first phase assisted the researcher to design social-cognitive strategies to promote exclusive breastfeeding among primiparous mothers using a Delphi survey. A Delphi survey design was used to assist the researcher to develop the social-cognitive strategies to promote exclusive breastfeeding among primiparous mothers. It consisted of three rounds of mailed self-completion questionnaires. The Delphi was supported with critical review and synthesis of literature throughout the strategies’ development process. Descriptive summary statistics were used to analyse the prenatal breastfeeding behaviour of 141 primiparous mothers followed from the last antenatal care visits up to six months after delivery. Bivariate correlational and multiple logistic regression analyses were used to identify the social cognitive determinants and predictors of exclusive breastfeeding within the first hour post-delivery and six months thereafter. Findings: Positive breastfeeding outcome expectancy and high breastfeeding self-efficacy were identified as the independent social cognitive predictors of exclusive breastfeeding among primiparous mothers in Ethiopia. These predictors were used to develop social cognitive strategies to promote exclusive breastfeeding, which comprise six main components: (1) scientific evidence for the strategies, (2) the rationale for the strategies, (3) the aim of the strategies, (4) the scope of the strategies, (5) the guiding principles, and (6) the key results areas. These strategies were developed and validated with the inputs from 37 experts on breastfeeding and social cognitive theory. Two key results areas (build individual capacity for exclusive breastfeeding and create an enabling environment) and five strategic objectives were formulated and validated. Conclusions: The successful implementation of the social cognitive strategies to promote exclusive breastfeeding among primiparous mothers in Addis Ababa, Ethiopia as described above will require among others (1) in-service training on social cognitive skills for healthcare providers with focus on how to build self-efficacy and outcome expectancy, (2) the development of self-efficacy and outcome expectance assessments tools relevant to the Ethiopian context, and (3) additional support and resources from the healthcare managers. Recommendations: To the researcher recommend that programs aimed at promoting exclusive breastfeeding practices among primiparous mothers should be based on the combined attributes of positive social cognitive outcome expectance and high breastfeeding self-efficacy. Further research is needed to develop assessment tools for breastfeeding self-efficacy and outcome expectancy before the implementation of the proposed strategies. / Health Studies / D.

Text in English / This study aimed at exploring Barriers to compliance with exclusive breastfeeding and timely introduction of complementary feeding practices in Ofla District, Tigray Region in Ethiopia. A quantitative exploratory descriptive study was conducted to explore and describe the barriers that restrict mothers /caregivers to comply with exclusive breast feeding practice until six months and with introduction of solid, semi-solid and soft foods at six months in Ofla District. Data were collected using structured questionnaire, from a total of 112 samples of which 75 mothers and care givers with children aged 0-5 months and 38 children aged 6-8 months participated. The data were entered into a computer and analysed though the Statistical Package for Social Sciences (SPSS) software. The findings revealed that there are barriers related Doer mothers and Non-Doer mothers perceived susceptibility, perceived severity, perceived benefits, perceived barriers, perceived self-efficacy, cues for actions, perceived social acceptability and positive and negative attitudes towards exclusive breastfeeding and initiation of complementary feeding. On the other hand, the participant’s perception of both groups with regard to perception of Divine (God’s) Will on two child feeding practices was insignificantly the same. Both groups perceived that children could get sometimes malnourished because of spiritual or supernatural causes. / Health Studies / M.A. (Public Health)
