Background. Hypertension is a growing public health problem in many developing countries including Ethiopia. Determining the prevalence of hypertension and identifying the associated factors is crucial. Objective. To assess the prevalence of hypertension and associated factors, among adult population of Arba Minch town, Gamo Zone, Southern Nations, Nationalities and Peoples Region, Ethiopia. Methods. A cross-sectional study design was conducted from December 1 to 30, 2017 among adults. Study participants were selected using a multistage systematic sampling method. Data were collected by face-to-face interview after getting written informed consent by using a structured questionnaire. Additionally, weight, height, and blood pressure of participants were measured following standard procedures. Data were entered into a computer using EPI INFO 7 and exported into SPSS version 20 for analysis. Bivariate and multivariable analyses were performed to explore the association between hypertension and associated factors. Multivariable logistic regressions were fitted to control the effect of confounders. Results. A total of 784 study participants were included in this study. The overall prevalence of hypertension in Arba Minch Town was 35.2%, (95% CI: 32.4%, 38.4%). Nearly 90% of hypertensive patients were screened for the first time. Age ≥55 years [AOR = 7:74; 95% CI: 2.19, 27.23], income level which is greater than 2501 Ethiopian Birr [AOR = 9:5; 95% CI: 4.5, 20.20], working hour less than seven hours per day [AOR = 12:5; 95% CI: 4.3, 36.1], and chewing "khat" [AOR = 11:06: 95% CI: 4.3, 27.7] were the independently associated factors with hypertension. Conclusion. The prevalence of hypertension is found to be high. Increasing awareness on control use of "khat," increasing physical activity, and strengthening community-based periodic screening programs of high-risk populations are recommended.

Transition metal complexes of Mnanganese (II) and Cobalt (III) were synthesized from the Schiff's base ligand, 3methoxy-4-hydroxyphenylmethyelene (2-hydroxyphenyl) amine which is derived from vanillin and 2-aminohpenol by the reaction of the metal ions. The Structural features of these complexes were obtained from their elemental analyses, magnetic susceptibility, molar conductance, FT-IR, electronic spectra, and Atomic Absorption Spectroscopic studies. In order to study the binding modes of the ligand (Schiff's base) with metal ions in the complexes, the FT-IR spectrum of the free ligand was compared with the spectra of its complexes. The spectral data suggest the involvement of phenolic oxygen and azomethane nitrogen in coordination to the central metal ions. On the basis of spectral studies and magnetic susceptibility measurements, an octahedral geometry has been assigned for both complexes. The free ligand and its metal complexes were tested in vitro against bacteria (Escherichia coli, Staphylococcus aureus) and fungi (Aspergillus Niger, Colletotricum) in order to assess their antimicrobial activities. And the results indicated that all compounds are effective against both tested bacteria and fungi though their effects are dose dependent. The free ligand showed higher activities than its complexes in both bacteria and fungi case, which suggests the promising potential of the ligand for both bacterial and fungi test.
