Prevalence and associated factors of hypertension among adults in Gondar, Northwest Ethiopia: a community based cross-sectional study

BackgroundHypertension is a growing public health problem in many developing countries including Ethiopia. However, its prevention and control has not yet received due attention. This study aimed to determine the prevalence and associated factors of hypertension among adults in Gondar city, North-West Ethiopia.MethodsA community based cross-sectional study was conducted in April 2012 in Gondar city. Participants aged 35 years and older were recruited using multi-stage random sampling technique. Data were collected by face-to-face interview technique after verbal informed consent. Additionally, weight, height and Blood Pressure (BP) of participants were measured following standard procedures. Hypertension was defined as having Systolic BP ≥140 mmHG or Diastolic BP≥ 90mmHG or reported use of regular anti-hypertensive medications prescribed by professionals for raised BP. Data were collected by clinical nurses and then entered into a computer using Epi Info version 3.5.3 and exported to SPSS version 20 for analysis. Multiple logistic regressions were fitted and Odds ratios with 95% confidence intervals were calculated to identify associated factors.ResultsA total of 679 participants were included in this study. About one in –five participants (21.0%) were aged 65 years or older. Obesity among all participants was 5.6%. Hundred ninety two (28.3%) were hypertensive of whom more than a third (37.0%) did not know they had hypertension. Family history of hypertension (AOR = 2.71, 95%CI; 1.37-5.36), obesity (AOR = 5.50, 95%CI; 2.07-14.62), self reported diabetes (AOR = 4.15, 95%CI; 1.77-9.72), age ≥ 55 years (AOR=3.33, 95%CI; 1.88-5.90) and not continuously walking for 10 minutes per day (AOR = 2.86, 95%CI; 1.15-7.12) were factors associated with hypertension.ConclusionThere was a high prevalence of hypertension probably indicating a hidden epidemic in this community. Age ≥ 55 years, obesity, family history of hypertension, physical inactivity and self reported diabetes were associated with hypertension. Hence, we recommend the design and implementation of community based screening programs.

Outcomes of TB treatment in HIV co-infected TB patients in Ethiopia: a cross-sectional analytic study

BackgroundTB and HIV are the most prevalent communicable diseases of major public health importance in the populations of sub-Saharan African countries, and an estimated 30 % of HIV infected persons have dual infection with TB. TB is the leading cause of death in HIV infected individuals, and HIV co-infected TB patients have multiple individual, disease specific and treatment related factors that can adversely affect their treatment outcomes. There is lack of evidence on the individual patient outcomes of HIV co-infected TB patients who receive anti-TB treatment. It is relevant to understand the differential patient outcomes of HIV co-infected TB patients and identify the factors that are associated with these outcomes.MethodsA comparative analysis was done on the data from a random sample of 575 TB patients who were enrolled for TB treatment from January 2013 to December 2013 at eight health facilities in Ethiopia. A descriptive analysis was done on the data, and chi-square test and logistic regression analysis was conducted to compare TB treatment outcomes based on HIV status and to identify factors associated with these outcomes.ResultsOut of a total of 575 TB patients enrolled into the study, 360 (62.6 %) were non-HIV infected, 169 (29.4 %) were HIV co-infected, and 46 (8 %) had no documented HIV status. The overall treatment success rate was 91.5 % for all the study participants. HIV co-infected TB patients have a treatment success rate of 88.2 % compared with 93.6 % for non-HIV infected study participants (P = 0.03). HIV co-infected TB patients had a significantly higher rate (11.8 % versus 6.4 %, P = 0.03) of unfavourable outcomes. The cure rate was significantly lower (10.1 % versus 24.2 %, P = 0.001) and the death rate higher in HIV co-infected TB patients (8.3 % versus 2.5 %, P = 0.014). Age and TB classification were significantly associated with treatment outcome. No association was found with starting ART, Cotrimoxazole prophylactic treatment or enrolment in HIV care.ConclusionsThere is high TB treatment success rate among patients who have been treated for TB, but the treatment success rate and the cure rate in HIV co-infected TB patients is lower than that observed in non-HIV infected patients. Patients with advanced age and those with smear positive pulmonary TB have unfavourable treatment outcomes.

Predictors of treatment failure on second-line antiretroviral therapy among adults in northwest Ethiopia: a multicentre retrospective follow-up study.

Background The number of patients using second-line antiretroviral therapy (ART) has increased over time. In Ethiopia, 1.5% of HIV infected patients on ART are using a second-line regimen and little is known about its effect in this setting. Objective To estimate the rate and predictors of treatment failure on second-line ART among adults living with HIV in northwest Ethiopia. Setting An institution-based retrospective follow-up study was conducted at three tertiary hospitals in northwest Ethiopia from March to May 2015. Participants 356 adult patients participated and 198 (55.6%) were males. Individuals who were on second-line ART for at least 6 months of treatment were included and the data were collected by reviewing their records. Primary outcome measure The primary outcome was treatment failure defined as immunological failure, clinical failure, death, or lost to follow-up. To assess our outcome, we used the definitions of the WHO 2010 guideline. Result The mean±SD age of participants at switch was 36±8.9 years. The incidence rate of failure was 61.7/1000 person years. The probability of failure at the end of 12 and 24 months were 5.6% and 13.6%, respectively. Out of 67 total failures, 42 (62.7%) occurred in the first 2 years. The significant predictors of failure were found to be: WHO clinical stage IV at switch (adjusted HR (AHR) 2.1, 95% CI 1.1 to 4.1); CD4 count <100 cells/mm3 at switch (AHR 2.0, 95% CI 1.2 to 3.5); and weight change (AHR 0.92, 95% CI 0.88 to 0.95). Conclusions The rate of treatment failure was highest during the first 2 years of treatment. WHO clinical stage, CD4 count at switch, and change in weight were found to be predictors of treatment failure.

Suicide ideation and attempts among people with epilepsy in Addis Ababa, Ethiopia

BackgroundSuicidal ideation and attempts are more frequent in people with epilepsy than in general population and suicide attempt increases the chance of later completed suicide. The aim of this study was to assess the prevalence and associated factors of suicidal ideation and attempt among people with epilepsy in Amanuel Mental Specialized Hospital, Addis Ababa, Ethiopia.MethodsInstitution-based cross-sectional study was conducted from May to June 2014 at Amanuel Mental Specialized Hospital among people with epilepsy. The pre-tested semi-structured questionnaire was used for interviewing the study participants. Logistic regression analysis was used to assess predictors of suicidal ideation and attempt.ResultsThe study indicated that the prevalence of suicidal ideation and attempt among people with epilepsy were 29.8 and 14.1%, respectively. Poor social support, drug treatment for mental illness, had co-morbid depression, no seizure free within 1 year and family history committed suicide were significantly associated with suicidal ideation and attempt.ConclusionThe prevalence of suicidal ideation and attempt in people with epilepsy found to be higher when compared to general population. Therefore, screening all epilepsy patients should be done for early diagnosis and treatment.

The prevalence of non-communicable diseases in northwest Ethiopia: survey of Dabat Health and Demographic Surveillance System

Objective The main objective of this study was to investigate the magnitude and associated factors of non-communicable chronic diseases (NCDs) at the Dabat Health and Demographic Surveillance System (DHDSS) site in the northwestern part of Ethiopia. Design A population-based cross-sectional study was conducted from October to December 2014. Setting HDSS site, Ethiopia. Participants A total population of 67 397 living in 16 053 households was included in the study. Measures Structured interviewer-administered questionnaire was used to collect data. Self-reported morbidity was used to ascertain NCD. A binary logistic regression model was employed to identify the determinants of NCDs. Result One thousand one hundred sixty (1.7%) (95% CI 1.62 to 1.82) participants were found with at least one type of NCD. Heart disease and hypertension which accounted for 404 (32.2%) and 401 (31.9%), of the burden, respectively, were the most commonly reported NCDs, followed by 347 (27.7%) asthma, 62 (4.9%) diabetes mellitus and 40 (3.2%) cancer cases. Advanced age (≥65 year) (adjusted OR (AOR)=19.6; 95% CI 5.83 65.70), urban residence (AOR=2.20; 95% CI 1.83 to 2.65), household food insecurity (AOR=1.71; 95% CI 1.37 to 2.12) and high income (AOR=1.28; 95% CI 1.02 to 1.59) were significantly associated with the reported history of NCDs, whereas low (AOR=0.36; 95% CI 0.31 to 0.42) and moderate (AOR=0.33; 95% CI 0.22 to 0.48) alcohol consumption, farming occupation (AOR=0.72; 95% CI 0.57 to 0.91), and work-related physical activities (AOR=0.66; 95% CI 0.50 to 0.88) were inversely associated with NCDs. Conclusion There is a high burden of NCDs at the Dabat HDSS site. Promotion of regular physical exercise and reducing alcohol consumption are essential to mitigate the burden of NCDs. In addition, preventive interventions of NCDs should be strengthened among urban dwellers, older age people and people of higher economic status.

Modeling Outcomes of First-Line Antiretroviral Therapy and Rate of CD4 Counts Change among a Cohort of HIV/AIDS Patients in Ethiopia: A Retrospective Cohort Study

Background Antiretroviral therapy has shown to be effective in reducing morbidity and mortality in patients infected with HIV for the past couples of decades. However, there remains a need to better understand the characteristics of long-term treatment outcomes in resource poor settings. The main aim of this study was to determine and compare the long-term response of patients on nevirapine and efavirenz based first line antiretroviral therapy regimen in Ethiopia. Methods Hospital based retrospective cohort study was conducted from January 2009 to December 2013 at University hospital located in Northwest Ethiopia. Human subject research approval for this study was received from University of Gondar Research Ethics Committee and the medical director of the hospital. Cox-proportional hazards model was used to assess the effect of baseline covariates on composite outcome and a semi-parametric mixed effect model was used to investigate CD4 counts response to treatments. Results A total of 2386 HIV/AIDS naive patients were included in this study. Nearly one-in-four patients experienced the events, of which death, lost to follow up, treatment substitution and discontinuation of Non-Nucleoside Reverse Transcriptase Inhibitors(NNRTI) accounted: 99 (26.8%), 122 (33.0%), 137 (37.0%) and 12 (3.2%), respectively. The hazard of composite outcome on nevirapine compared with efavirenz was 1.02(95%CI: 0.52-1.99) with p-value = 0.96. Similarly, the hazard of composite outcome on tenofovir and stavudine compared with zidovudine were 1.87 (95%CI: 1.52-2.32), p-value < 0.0001 and 1.72(95% CI: 1.22-2.32), p-value = 0.002, respectively. The rate of CD4 increase in response to treatment was high during the first 10 months and stabilized later. Conclusions This study revealed that treatment responses were comparable whether nevirapine or efavirenz was chosen to initiate antiretroviral therapy for HIV/AIDS patients in Ethiopia. There was significant difference on risk of composite outcome between patients who were initiated with Tenofovir containing ART regimen compared with zidovudine after controlling for NNRTI drug combinations.

Reducing amount and frequency of meal as a major coping strategy for food insecurity

BackgroundFood insecurity is a global problem affecting many people worldwide, including approximately 220 million people in sub-Saharan Africa. Ethiopia is among the countries severely affected by hunger. However, evidence on how populations within Ethiopia cope with hunger and food insecurity is limited. This study aimed to identify household coping mechanisms in response to food insecurity at a Dabat Health and Demographic Surveillance System site.MethodsThis study used data from a re-census collected between October 2014 and December 2014.15,159 household members in thirteen kebeles of the Dabat Health and Demographic surveillance system were included. The outcome variables of the study were food insecurity and coping strategies. Household Food Insecurity Access Scale (HFIAS) was used to assess food insecurity. If food insecurity was found, families were asked about coping mechanisms used. Binary logistic regression analysis was applied to identify socio-demographic determinants of reducing amount and frequency of meal as a coping mechanism in response to food insecurity.ResultOf the 15,159 households surveyed, 6671 (44.01%) reported the presence of a food insecurity in their household. Decreasing meal frequency and portions (3733 (55.96%)), borrowing money and food (2542 (38.11%)), and receiving food and money aid (1779 (26.67%)) were among the major coping strategies used by the households. Urban dwellers (AOR 2.07: 95% CI 1.74, 2.46), mid-altitude (weyina-dega) and high-land (dega) dwellers (AOR 2.46: 95% CI 2.08, 2.92 and AOR 1.22 95% CI 1.08, 1.38 respectively), and not married persons (AOR 1.60: 95% CI 1.07, 2.39) were more likely to consume less when faced with a food insecurity (using reducing amount and frequency of meal as a coping strategy).ConclusionHouseholds in the study area experienced a very high rate of food insecurity. Decreasing meal frequency and portions was the primary coping mechanism used by the households. Due to the severe insecurity of food in their household, many people chose to reduce the amount and frequency of their meal in order to prolong the small amount of food in their house. This finding indicates a high risk for undernourishment which can exacerbate the burden of malnutrition and related diseases in the region.

Determinants of depression among people with epilepsy in Central Ethiopia

BackgroundDepression is the most frequently and highly occurring mental disorders in epilepsy patients. When depression is comorbid with epilepsy, it leads to low employment and poor quality of life. Thus, the aim of this study was to assess the prevalence and associated factors of depression among people living with epilepsy in Central Ethiopia.MethodsInstitution-based cross-sectional study was conducted from April to May 2015 at Amanuel Mental Specialized and TikurAnbesa Hospitals, Addis Ababa, Ethiopia. Samples of 422 epilepsy patients were selected, and data on depression were collected using validated questionnaire using face-to-face interview technique. Logistic regression analysis was performed to assess predictors of depression.ResultsThe study indicated that the prevalence of depression among people with epilepsy was 43.8%. Factors associated with depression were being female (AOR 2.48; 95% CI, 1.61.3.81), being single (AOR 2.23; 95% CI 1.38–3.60), perceived stigma (AOR 2.47; 95% CI 1.59–3.83), medication adherence (AOR 2.85; 95% CI 1.64–4.96), and current substance use (AOR 2.10; 95% CI 1.34–3.30).ConclusionThere is a high prevalence of depression among epilepsy patients. Early detection and prompt management of depressive symptoms are critically important in reducing depression burden among people living with epilepsy.

Tuberculosis and HIV are the leading causes of adult death in northwest Ethiopia: evidence from verbal autopsy data of Dabat health and demographic surveillance system, 2007–2013

BackgroundReliable data on causes of death form the basis for building evidence on health policy, planning, monitoring, and evaluation. In Ethiopia, the majority of deaths occur at home and civil registration systems are not yet functional. The main objective of verbal autopsy (VA) is to describe the causes of death at the community or population level where civil registration and death certification systems are weak and where most people die at home without having had contact with the health system.MethodsCauses of death were classified and prepared based on the International Classification of Diseases (ICD-10). The cause of a death was ascertained based on an interview with next of kin or other caregivers using a standardized questionnaire that draws information on signs, symptoms, medical history, and circumstances preceding death. The cause of death, or the sequence of causes that led to death, is assigned based on the data collected by the questionnaire. The complete VA questionnaires were given to two blinded physicians and reviewed independently. A third physician was assigned to review the case when disagreements in diagnosis arose.ResultsCommunicable diseases (519 deaths [48.0%]), non-communicable diseases (377 deaths [34.8%]), and external causes (113 deaths [10.4%]) were the main causes of death between 2007 and 2013. Of communicable diseases, tuberculosis (207 deaths [19.7%]), HIV/AIDS (96 deaths [8.9%]) and meningitis (76 deaths [7.0%]) were the most common causes of death.ConclusionTuberculosis, HIV/AIDS, and meningitis were the most common causes of deaths among adults. Death due to non-communicable diseases showed an increasing trend. Increasing community awareness of infections and their interrelationships, tuberculosis case finding, effective local TB programs, successful treatment, and interventions for HIV are supremely important.BACKGROUND Reliable data on causes of death form the basis for building evidence on health policy, planning, monitoring, and evaluation.
