Determinants of low family planning use and high unmet need in Butajira District, South Central Ethiopia

<p>Abstract</p> <p>Background</p> <p>The rapid population growth does not match with available resource in Ethiopia. Though household level family planning delivery has been put in place, the impact of such programs in densely populated rural areas was not studied. The study aims at measuring contraception and unmet need and identifying its determinants among married women.</p> <p>Methods</p> <p>A total of 5746 married women are interviewed from October to December 2009 in the Butajira Demographic Surveillance Area. Contraceptive prevalence rate and unmet need with their 95% confidence interval is measured among married women in the Butajira district. The association of background characteristics and family planning use is ascertained using crude and adjusted Odds ratio in logistic regression model.</p> <p>Results</p> <p>Current contraceptive prevalence rate among married women is 25.4% (95% CI: 24.2, 26.5). Unmet need of contraception is 52.4% of which 74.8% was attributed to spacing and the rest for limiting. Reasons for the high unmet need include commodities' insecurity, religion, and complaints related to providers, methods, diet and work load. Contraception is 2.3 (95% CI: 1.7, 3.2) times higher in urbanites compared to rural highlanders. Married women who attained primary and secondary plus level of education have about 1.3 (95% CI: 1.1, 1.6) and 2 (95% CI: 1.4, 2.9) times more risk to contraception; those with no child death are 1.3 (95% CI: 1.1, 1.5) times more likely to use contraceptives compared to counterparts. Besides, the odds of contraception is 1.3 (95% CI: 1.1, 1.6) and 1.5 (1.1, 2.0) times more likely among women whose partners completed primary and secondary plus level of education. Women discussing about contraception with partners were 2.2 (95% CI: 1.8, 2.7) times more likely to use family planning. Nevertheless, contraception was about 2.6 (95% CI: 2.1, 3.2) more likely among married women whose partners supported the use of family planning.</p> <p>Conclusions</p> <p>The local government should focus on increasing educational level. It must also ensure family planning methods security, increase competence of providers, and create awareness on various methods and their side effects to empower women to make an appropriate choice. Emphasis should be given to rural communities.</p

Malaria Vectors in Lake Victoria and Adjacent Habitats in Western Kenya

The prevalence of malaria among the residents of the Lake Victoria basin remains high. The environment associated with the lake may maintain a high number of malaria vectors. Lake habitats including water hyacinths have been suspected to be the source of vectors. This study investigated whether malaria vectors breed in the lake habitats and adjacent backwater pools. Anopheline larvae were collected within the littoral zone of the lake and adjacent pools located along approximately 24.3 km of the lakeshore in western Kenya, and their breeding sites characterized. Three primary vector species, Anopheles arabiensis, Anopheles gambiae s.s. and Anopheles funestus s.s., and three potential vectors, were found in the lake habitats. Unexpectedly, An. arabiensis was the most dominant vector species in the lake sampling sites. Its habitats were uncovered or covered with short grass. A potential secondary malaria vector, Anopheles rivulorum, dominated the water hyacinths in the lake. Most breeding sites in the lake were limited to areas that were surrounded by tall emergent plants, including trees, and those not exposed to waves. Nearly half of adjacent habitats were lagoons that were separated from the lake by sand bars. Lagoons contained a variety of microhabitats. Anopheles arabiensis dominated open habitats, whereas An. funestus s.s. was found mainly in vegetated habitats in lagoons. The current study confirmed that several breeding sites are associated with Lake Victoria. Given that Lake Victoria is the second largest lake in the world, the lake related habitats must be extensive; therefore, making targeted vector control difficult. Further exploration is necessary to estimate the effects of lake associated habitats on malaria transmission so as to inform a rational decision-making process for vector control

Yield response of barley to the application of mineral fertilizers containing major nutrients on Cambisols and Vertisols in Ethiopia

Increasing barley production in the face of declining soil fertility on smallholder farms is a critical challenge in Ethiopia. The objectives of this study were to (1) determine the optimum rates of nitrogen (N), phosphorus (P), potassium (K), and sulfur (S) fertilizers under a balanced fertilization of other macro- and micronutrients (zinc and boron) and (2) quantify the agronomic efficiency of N and P on Cambisols and Vertisols. The trials were conducted for three consecutive years (2014–2016) on farmers’ fields on 83 sites under rain-fed conditions. On each farm, six rates of N, P, K, and S with a balanced application of the other nutrients were laid out separately in a randomized block design with three replicates. Balanced fertilization resulted in yield increments of 26–59% on Cambisols and 18–74% on Vertisols, as compared with the control (0 N). Application of P increased grain yield from 11% to 30% and from 7% to 14% due to the interaction of P by soil type as compared with the control. The application of K and S, however, had no significant effect on barley yields on either soil type. The highest agronomic efficiency of N (AEN) was obtained from 46 kg N ha−1, with AEN increasing by 117% on Cambisols and 33% on Vertisols, as compared with the highest N rate of 230 kg N ha−1. The maximum agronomic efficiency of P (AEP) was recorded with 10 kg P ha−1 on Vertisols, with AEP increasing by 73% on Cambisols and 452% on Vertisols, as compared with the application of 50 kg P ha−1. With balanced application of other nutrients, use of 230 kg N and 20 kg P ha−1 was recommended for tepid sub-moist mid-highlands and Vertisols. For tepid sub-humid mid-highlands, application of 46 kg N and 20 kg P ha−1 with balanced application of other nutrients was recommended. For Cambisols, application of 230 kg N and 40 kg P ha−1 was recommended with balanced application of the other nutrients. Similarly, application of 230 kg N, 40 kg P, and 10 kg S ha−1 was tentatively recommended for cool sub-most mid highlands. However, response to K was inconsistent and therefore a firm recommendation could not be proposed for the study sites. Further research needs to be conducted on more soil types and locations
