Determination of body composition of people living with HIV/AIDS: A comparison of air displacement plethysmography with Tanita segmental body composition analyzer

Background: Body composition (BC) assessment of patients living with HIV is frequently done by a variety of methods. During the past decades, several new technologic developments have introduced different methods of BC assessment. Yet, simple, accurate, and noninvasive methods for assessing BC are needed in clinical, community, and research settings. Objective: To compare BC assessed by air displacement plethysmography (ADP) with that assessed by Tanita segmental BC analyzer in patients with HIV/AIDS.Method: Eighty-eight adult (> 18 years) HIV/AIDS patients who were on follow up at anti-retroviral clinic in Jimma university medical centre were randomly selected. ADP and Tanita segmental BC analyzer were used to collect data. Agreement between the methods was tested using paired t-test, Pearson’s correlation, and linear regression. Result: Thirty-nine (57.4%) of the patients were female and 29 (42.6%) were male. About 41(60.3%) of them were malnourished. The patients who were in stage one of the disease accounted 83.8%. Mean value of %BF measured by Tanita segmental BC analyzer was significantly lower than %BF measured by the ADP (mean difference = 3.2, p < 0.001). Regardless of the difference in mean, %BF assessed by the two methods were strongly correlated (r = 0.98, p < 0.001). Conclusion: Estimates of %BF by Tanita segmental BC analyzer and ADP in people living with HIV/AIDS in Southwest Ethiopia showed significant difference. Tanita segmental BC analyzer significantly underestimated %BF in HIV/AIDS patients

Effect of Some Threshing Parameters on Sesame Separation

The threshing section on combine harvester or thresher machine affects grain and stalk separation performance. In this study, effect of some threshing parameters such as drum speed, feed rate and concave open on closed capsules sesame straw sieve in developed threshing unit. Threshing drums used were a rasp bar with tooth type. Three threshing drum speeds of 500, 700 and 900 min-1 (6.5, 9.1, 11.7 m/s) were used to investigations. Three feed rate as 90, 180 and 270 kg/h and three concave open as 20, 35 and 50 mm were used in this study. Four sieves were used for separation of straw. Their mesh numbers are 7, 10, 14 and 18. Results show that the best performance for separation of sesame straw were gave at the maximum drum speeds, minimum feed rates and concave opens experienced in this study

A Farmer-based fruit seedling supply system in Dale Pilot Learning Woreda (PLW): experiences from IPMS

Dale Woreda is well known for its avocado (Persia americana) and to a lesser extent mango (Mangifera indica) production. These fruit trees are planted along with coffee (Coffee arabica), enset (Enset ventricosum) and other crops. They are important sources of income and food, playing a considerable role in the livelihood of thousands of smallholder farmers of Dale. However, the varieties found in the area have large canopies that reduce land availability for other crops. They are also tall (10-15 m) thus harvesting becomes a challenge, particularly for women. Market prices for these varieties are low and during collection, there is considerable fruit loss when they fall, causing cracks and bruises and hence their rejection. The trees also take 7- 10 years to bear fruit and farmers mention that the land can be used more productively and therefore want to replace fruit trees with other more profitable crops. The diagnostic survey carried out by Improving Productivity and Marketing Success (IPMS) of Ethiopian farmers’ project identified some of the above production constraints as the major area of intervention. Further study was conducted by the International Centre for Research on Agro Forestry (ICRAF) which confirmed the above problems and suggested introduction of improved variety through grafting as one of the best solution to improve the quality of seed, reduce size and height as well as improve productivity and marketability of these varieties. Taking the experience of Dale for coffee seedling production where farmer’s nurseries have taken over 95% of seedling production, the Dale partners decided to use farmers’ nurseries as the base to start production of grafted seedlings. Using participatory extension methods with the help of various partners, the number of private nursery operators increased from the initial six (3 females) to 20 (7 female) in 2009. The number of seedlings produced has now reached 12,000 annually and this can be easily expanded since scions can now be obtained from mother trees established earlier in each of the nursery sites. Currently, seedlings are sold at around Birr 15/seedling to neighboring farmers, some on credit provided by the nursery operators. Linkages with the Productive Safety Net program are made to facilitate the scaling out of the sale of seedlings to emerging commercial farmers. Nursery operators earned between Birr 4,000–7,000 per year from these operations. Further skills development can still be made to improve survival rates of grafted seedlings. Attention will also need to be paid to the marketing of these improved varieties as well as the development of a responsive support system providing fresh knowledge, building capacity and new technologies

The impact of Ethiopia’s pilot community based health insurance scheme on healthcare utilization and cost of care

In recent years there has been a proliferation of Community Based Health Insurance (CBHI) schemes designed to enhance access to modern health care services and provide financial protection to workers in the informal and rural sectors. In June 2011, the Government of Ethiopia introduced a pilot CBHI scheme in rural parts of the country. This paper assesses the impact of the scheme on utilization of modern health care and the cost of accessing health care. It adds to the relatively small body of work that provides a rigorous evaluation of CBHI schemes. We find that enrolment leads to a 30 to 41 percent increase in utilization of outpatient care at public facilities, a 45 to 64 percent increase in the frequency of visits to public facilities and at least a 56 percent decline in the cost per visit to public facilities. The effects of the scheme on out-of-pocket spending are not as clear. The impact on utilization and costs combined with a high uptake rate of almost 50 percent within two years of scheme establishment, suggests that this scheme has the potential to meet the goal of universal access to health care

Self-reported health care seeking behavior in rural Ethiopia: Evidence from clinical vignettes

Between 2000 and 2011, Ethiopia rapidly expanded its health-care infrastructure recording an 18-fold increase in the number of health posts and a 7-fold increase in the number of health centers. However, annual per capita outpatient utilization has increased only marginally. The extent to which individuals forego necessary health care, especially why and who foregoes care are issues that have received little attention in the context of low-income countries. This paper uses five clinical vignettes covering a range of context-specific child and adult-related diseases to explore the health-seeking behavior of rural Ethiopian households. We find almost universal preference for modern care. There is a systematic relationship between socioeconomic status and choice of providers mainly for adult-related conditions with households in higher consumption quintiles more likely to seek care in health centers, private/NGO clinics as opposed to health posts. Similarly, delays in care-seeking behavior are apparent mainly for adult-related conditions. The differences in care seeking behavior between adult and child related conditions may be attributed to the recent spread of health posts which have focused on raising awareness of maternal and child health. Overall, the analysis suggests that the lack of health-care utilization is not driven by the inability to recognize health problems or due to a low perceived need for modern care but due to other factors

Healthcare-seeking behaviour in rural Ethiopia: Evidence from clinical vignettes

__Abstract__ Objectives: To investigate the determinants of healthcare-seeking behaviour using five contextrelevant clinical vignettes. The analysis deals with three issues: whether and where to seek modern care and when to seek care. Setting: This study is set in 96 villages located in four main regions of Ethiopia. The participants of this study are 1632 rural households comprising 9455 individuals. Primary and secondary outcome measures: Probability of seeking modern care for symptoms related to acute respiratory infections/pneumonia, diarrhoea, malaria, tetanus and tuberculosis. Conditional on choosing modern healthcare, where to seek care (health post, health centre, clinic and hospital). Conditional on choosing modern healthcare, when to seek care (seek care immediately, the next day, after 2 days, between 3 days to 1 week, a week or more). Results: We find almost universal preference for modern care. Foregone care ranges from 0.6% for diarrhoea to 2.5% for tetanus. There is a systematic relationship between socioeconomic status and choice of providers mainly for adult-related conditions with households in higher consumption quintiles more likely to seek care in health centres, private/Non-Government Organization (NGO) clinics as opposed to health posts. Delays in care-seeking behaviour are apparent mainly for adult-related conditions and among poorer households. Conclusions: The analysis suggests that the lack of healthcare utilisation is not driven by the inability to recognise health problems or due to a low perceived need for modern care

Coping with shocks in rural Ethiopia

Based on household survey data and event history interviews undertaken in a highly shock prone country, this paper investigates which shocks trigger which coping responses and why? We find clear differences in terms of coping strategies across shock types. The two relatively covariate shocks, that is, economic and natural shocks are more likely to trigger reductions in savings and in food consumption while the sale of assets and borrowing is less common. Coping with relatively idiosyncratic health shocks is met by reductions in savings, asset sales and especially a far greater reliance on borrowing as compared to other shocks. Reductions in food consumption, a prominent response in the case of natural and economic shocks is notably absent in the case of health shocks. Across all shock types, households do not rely on gifts from family and friends or on enhancing their labour supply as coping approaches. The relative insensitivity of food consumption to health shocks based on the shocks-coping analysis presented here is consistent with existing work which examines consumption insurance. However, our analysis leads to a different interpretation. We argue that this insensitivity should not be viewed as insurability of food consumption against health shocks but rather as an indication that a reduction in food consumption is not a viable coping response to a health shock as it does not provide cash to meet health care needs
