Trends of modern contraceptive use among young married women based on the 2000, 2005, and 2011 Ethiopian Demographic and Health Surveys: a multivariate decomposition analysis

Published: January 30, 2015Introduction: Accessing family planning can reduce a significant proportion of maternal, infant, and childhood deaths. In Ethiopia, use of modern contraceptive methods is low but it is increasing. This study aimed to analyze the trends and determinants of changes in modern contraceptive use over time among young married women in Ethiopia. Methods: The study used data from the three Demographic Health Surveys conducted in Ethiopia, in 2000, 2005, and 2011. Young married women age 15–24 years with sample sizes of 2,157 in 2000, 1,904 in 2005, and 2,146 in 2011 were included. Logit-based decomposition analysis technique was used for analysis of factors contributing to the recent changes. STATA 12 was employed for data management and analyses. All calculations presented in this paper were weighted for the sampling probabilities and non-response. Complex sampling procedures were also considered during testing of statistical significance. Results: Among young married women, modern contraceptive prevalence increased from 6% in 2000 to 16% in 2005 and to 36% in 2011. The decomposition analysis indicated that 34% of the overall change in modern contraceptive use was due to difference in women’s characteristics. Changes in the composition of young women’s characteristics according to age, educational status, religion, couple concordance on family size, and fertility preference were the major sources of this increase. Two-thirds of the increase in modern contraceptive use was due to difference in coefficients. Most importantly, the increase was due to change in contraceptive use behavior among the rural population (33%) and among Orthodox Christians (16%) and Protestants (4%). Conclusions: Modern contraceptive use among young married women has showed a remarkable increase over the last decade in Ethiopia. Programmatic interventions targeting poor, younger (adolescent), illiterate, and Muslim women would help to maintain the increasing trend in modern contraceptive use.Abebaw Gebeyehu Worku, Gizachew Assefa Tessema, Atinkut Alamirrew Zelek

Yam breeding at IITA: achievements, challenges, and prospects

African food system Yam (Dioscorea spp.) is a multispecies, clonally propagated crop cultivated for its starchy tubers. About 10 species are widely cultivated around the world, but only D. rotundata, D. alata, and D. cayenensis are the most widely cultivated species in West Africa, accounting for 93% of the global yam production. Since inception, IITA R4D efforts have focused on developing new varieties of yam with desired agronomic and quality traits and to improve yam-based cropping systems

Prevalence, Reasons, and Perceived Effects of Khat Chewing Among Students of a College in Gondar Town, Northwestern Ethiopia: A Cross‑sectional Study

Background: The estimate of the number of people chewing Khat globally ranges from 5 to 10 million people. Its use may result in a variety of effects due to the different compounds in it with effects on the gastro‑intestinal system and nervous system being the principal ones. Aim: To assess the prevalence, factors, and effects of Khat chewing among students of a college in Gondar town, northwestern Ethiopia. Subjects and Methods: An institution‑based cross‑sectional study was conducted from 15th to 20th of April 2009 on a total sample of 424 students who were selected using stratified random sampling technique. Data were collected by three of the principal investigators using a structured pretested data collection instrument and analyzed by Epi Info version 3.5.2. Results: The lifetime and current prevalence of Khat chewing among the respondents were 42% (168/400) and 32.5% (130/400), respectively. Sex (P < 0.01), religion (P < 0.001), and income (P < 0.01) showed statistically significant variation in Khat chewing. The commonest frequency of Khat chewing was once a day 33.1% (43/130) while alcohol (40.8% [53/130]) and cigarette (40.0% [52/130]) were the mostly used substances with Khat. More than half of the chewers (53.85% [70/130]) reported spending 1–4 h for one Khat chewing ceremony. Financially majority of the chewers reported spending up to 10 Ethiopian Birr (ETB) (1.13 United States Dollar) on Khat ( 54.6% [71/130]) and other substances (64.6% [84/130]). Nearly two‑thirds (62.3% [81/130]) of the chewers mentioned seeking concentration during study as their main reason for chewing. Among chewers, 83.1% (108/130) reported they faced problem associated to sleep disturbance, 82.3% (107/130) loss of appetite, and 80.8% (105/130) constipation. Conclusion: The prevalence of Khat chewing was fairly high among the students and the majority among them used other substances together with Khat. Spending of a significant amount of money and facing health problems were reported to be consequences of the habit. The college should take steps to make students aware of the ills of Khat chewing and associated habits.Keywords: College, Effects, Gondar, Khat, Prevalence, Reason

Population Based Survey of Chronic Non-Communicable Diseases at Gilgel Gibe Field Research Center, Southwest Ethiopia

BACKGROUND: Chronic Non-communicable Diseases are increasingly becoming more prevalent and burden to the health care system in developing countries including Ethiopia. However, evidences showing the magnitude of the problem in those countries are scarce particularly in a community setting.The objective of this study was to determine the magnitude of chronic non communicable diseases in a community.METHODS: A population-based cross-sectional study was conducted in Gilgel Gibe Field Research Center from late September 2008 to end of January 2009. A random sample of 4,469 individuals aged 15-64 years was studied. Data on characteristics and chronic symptom inventories were collected by interviewing study participants. Blood pressure was taken three times from each individual and blood sugar and lipid levels were determined after an overnight fasting. Data were analyzed using SPSS for Windows version 16.0 and STATA 11.RESULTS: The overall prevalence of CNCD was 8.9% (7.8% men and 9.8% women). The specific observed prevalence were 0.5% for diabetes mellitus (DM), 2.6% for hypertension, 3.0% for cardiovascular diseases, 1.5% for asthma and 2.7% for mental illness. In addition 3.1% and 9.3% of the study population had been informed to have DM and hypertension respectively.CONCLUSION: There is a high prevalence of CNCD among the study population indicating an immediate need for preventive action and also warrant further nationally representative study.Keywords: CNCD, Non-communicable, Prevalence, Southwest Ethiopi

Global, regional, and national levels of maternal mortality, 1990–2015 : a systematic analysis for the Global Burden of Disease Study 2015

Background In transitioning from the Millennium Development Goal to the Sustainable Development Goal era, it is imperative to comprehensively assess progress toward reducing maternal mortality to identify areas of success, remaining challenges, and frame policy discussions. We aimed to quantify maternal mortality throughout the world by underlying cause and age from 1990 to 2015. Methods We estimated maternal mortality at the global, regional, and national levels from 1990 to 2015 for ages 10–54 years by systematically compiling and processing all available data sources from 186 of 195 countries and territories, 11 of which were analysed at the subnational level. We quantifi ed eight underlying causes of maternal death and four timing categories, improving estimation methods since GBD 2013 for adult all-cause mortality, HIVrelated maternal mortality, and late maternal death. Secondary analyses then allowed systematic examination of drivers of trends, including the relation between maternal mortality and coverage of specifi c reproductive health-care services as well as assessment of observed versus expected maternal mortality as a function of Socio-demographic Index (SDI), a summary indicator derived from measures of income per capita, educational attainment, and fertility. Findings Only ten countries achieved MDG 5, but 122 of 195 countries have already met SDG 3.1. Geographical disparities widened between 1990 and 2015 and, in 2015, 24 countries still had a maternal mortality ratio greater than 400. The proportion of all maternal deaths occurring in the bottom two SDI quintiles, where haemorrhage is the dominant cause of maternal death, increased from roughly 68% in 1990 to more than 80% in 2015. The middle SDI quintile improved the most from 1990 to 2015, but also has the most complicated causal profi le. Maternal mortality in the highest SDI quintile is mostly due to other direct maternal disorders, indirect maternal disorders, and abortion, ectopic pregnancy, and/or miscarriage. Historical patterns suggest achievement of SDG 3.1 will require 91% coverage of one antenatal care visit, 78% of four antenatal care visits, 81% of in-facility delivery, and 87% of skilled birth attendance. Interpretation Several challenges to improving reproductive health lie ahead in the SDG era. Countries should establish or renew systems for collection and timely dissemination of health data; expand coverage and improve quality of family planning services, including access to contraception and safe abortion to address high adolescent fertility; invest in improving health system capacity, including coverage of routine reproductive health care and of more advanced obstetric care—including EmOC; adapt health systems and data collection systems to monitor and reverse the increase in indirect, other direct, and late maternal deaths, especially in high SDI locations; and examine their own performance with respect to their SDI level, using that information to formulate strategies to improve performance and ensure optimum reproductive health of their population.GBD 2015 Maternal Mortality Collaborators ...Nicholas J Kassebaum ...

Diabetic and Hypertensive Disorders Following Miscarriage: A Protocol for Systematic Review and Meta-Analysis

(1) Background: Miscarriages occur in approximately 15–25% of all pregnancies. There is limited evidence suggesting an association between history of miscarriage and the development of diabetic and hypertensive disorders in women. This systematic review aims to collate the existing literature and provide up to date epidemiological evidence on the topic. (2) Methods: We will search CINAHL Plus, Ovid/EMBASE, Ovid/MEDLINE, ProQuest, PubMed, Scopus, Web of Science, and Google Scholar, using a combination of medical subject headings, keywords, and search terms, for relevant articles related to the association between miscarriage and the risk of diabetic and hypertensive disorders. Cross-sectional, case–control, nested case–control, case–cohort, and cohort studies published from inception to April 2022 will be included in the search strategy. Three reviewers will independently screen studies and the risk of bias will be assessed using the Joanna Briggs Institute Critical Appraisal tool. Where the data permit, a meta-analysis will be conducted. (3) Results: The results of this systematic review will be submitted to a peer-reviewed journal for publication. (4) Conclusions: The findings of this systematic review will instigate efforts to manage and prevent reproductive, cardiovascular, and metabolic health consequences associated with miscarriages.Damien Foo, Jennifer Dunne, Gavin Pereira, Amanuel Gebremedhin, Bereket Duko, and Gizachew A.

Earnings smoothing and CEO cash bonus compensation: The role of mandatory derivatives disclosure policy

© 2018 Macmillan Publishers Ltd., part of Springer Nature. Motivated by intense controversy over mandatory derivative instruments disclosure required by the Statement of Financial Accounting Standard No. 133 (SFAS 133), this study is to examine whether the sensitivity of CEOs compensation to earnings smoothing changes following the adoption of SFAS 133. Moreover, the study investigates whether the sensitivity of CEOs compensation to earnings smoothing after the implementation of SFAS 133 varies with the level of market volatility. Using the correlation between the changes in discretionary accruals and the changes in pre-discretionary income as a measure of earnings smoothing and dollar value of a bonus earned by the CEOs during the year as a measure of CEOs compensation, the empirical evidence reveals that while earnings smoothing and CEOs compensation are positively related, the positive relation is stronger after the adoption of SFAS 133. The study also finds that the positive association between earnings smoothing and CEOs compensation after the adoption of SFAS 133 is larger when the market volatility is higher. This study provides direct evidence on the impact of the adoption of SFAS 133 on the sensitivity of CEO compensation to earnings smoothing and sheds light on current literature on the effects of accounting regulations, earnings smoothing, and compensation plan. Moreover, this study helps standard setters to better understand the trade-off between transparency and compensation plans

A manual for large-scale sample collection, preservation, tracking, DNA extraction, and variety identification analysis

Several alternative options have been used for varietal identification. However most of the traditional methods have inherent uncertainty levels and estimates often have wide confidence intervals. In an attempt to circumvent traditional survey-based measurement errors in varietal identification, DNA-based varietal identification has been implemented in the Cassava Monitoring Survey (CMS) of Nigeria — a large adoption study involving 2500 cassava farming households. The DNA fingerprinting technique offers a reliable method to accurately identify varieties grown by farmers and increases accuracy and credibility in the interpretation of adoption rates and associated economic and policy analyses. Unlike phenotype-based methods, DNA is not affected by environmental conditions or plant growth stage and is more abundant than morphological descriptors. However, undertaking a credible DNA-based varietal identification is not a trivial matter because of the logistical challenges involving sample collection and tracking by a large team of field enumerators. This manual presents the detailed steps required for undertaking reliable DNA-fingerprinting-based identification of cassava varieties. In particular, the manual gives detailed information on the establishment of a sample tracking system, preparation of a readily available and cheap sample collection kit, field sample collection methodology, preparation of samples for DNA isolation, and development of a pipeline for variety identification analysis. This manual is part of the outputs of the CMS project funded by the CGIAR Research Program on Roots, Tubers and Bananas (RTB), the Bill & Melinda Gates Foundation, and the International Institute of Tropical Agriculture (IITA)

NbSe3: Effect of Uniaxial Stress on the Threshold Field and Fermiology

We have measured the effect of uniaxial stress on the threshold field ET for the motion of the upper CDW in NbSe3. ET exhibits a critical behavior, ET ~ (1 - e/ec)^g, wher e is the strain, and ec is about 2.6% and g ~ 1.2. This ecpression remains valid over more than two decades of ET, up to the highest fields of about 1.5keV/m. Neither g nor ec is very sensitive to the impurity concentraction. The CDW transition temperature Tp decreases linearly with e at a rate dTp/de = -10K/%, and it does not show any anomaly near ec. Shubnikov de-Haas measurements show that the extremal area of the Fermi surface decreases with increasing strain. The results suggest that there is an intimate relationship between pinning of the upper CDW and the Fermiology of NbSe3.Comment: 4 pages, 5 figure
