Sociodemographic Factors Predicting Exclusive Breastfeeding in Ethiopia: Evidence from a Meta-analysis of Studies Conducted in the Past 10 Years.

OBJECTIVES: To investigate the association between EBF and educational status, household income, marital status, media exposure, and parity in Ethiopia. METHODS: PubMed, EMBASE, Web of Science, SCOPUS, CINAHL and WHO Global health library databases were searched using key terms for all studies published in English between September 2009 and March 2019. The methodological quality of studies was examined using the Newcastle-Ottawa Scale (NOS) for cross-sectional studies. To obtain the pooled odds ratio (OR), extracted data were fitted in a random-effects meta-analysis model. Statistical heterogeneity was quantified using Cochran's Q test, τ2, and I2 statistics. In addition, Jackknife sensitivity analysis, cumulative meta-analysis, and meta-regression analysis were conducted. RESULTS: Out of 553 studies retrieved, 31 studies fulfilled our inclusion criteria. Almost all included studies were conducted among mothers with newborn less than 23 months old. Maternal primary school education (OR 1.39; 95% CI 1.03-1.89; I2 = 86.11%), medium household income (OR 1.27; 95% CI 1.05-1.55; I2 = 60.9%) and being married (OR 1.39; 95% CI 1.05-1.83; I2 = 76.96%) were found to be significantly associated with EBF. We also observed an inverse dose-response relationship of EBF with educational status and income. However, EBF was not significantly associated with parity, media exposure, and paternal educational status. CONCLUSIONS: In this meta-analysis, we showed the relevant effect of maternal education, income, and marital status on EBF. Therefore, multifaceted, effective, and evidence-based efforts are needed to increase the national level of exclusive breastfeeding in Ethiopia.

Neighbourhood socioeconomic status and overweight/obesity: a systematic review and meta-analysis of epidemiological studies.

OBJECTIVE: Low neighbourhood socioeconomic status (NSES) has been linked to a higher risk of overweight/obesity, irrespective of the individual's own socioeconomic status. No meta-analysis study has been done on the association. Thus, this study was done to synthesise the existing evidence on the association of NSES with overweight, obesity and body mass index (BMI). DESIGN: Systematic review and meta-analysis. DATA SOURCES: PubMed, Embase, Scopus, Cochrane Library, Web of Sciences and Google Scholar databases were searched for articles published until 25 September 2019. ELIGIBILITY CRITERIA: Epidemiological studies, both longitudinal and cross-sectional ones, which examined the link of NSES to overweight, obesity or BMI, were included. DATA EXTRACTION AND SYNTHESIS: Data extraction was done by two reviewers, working independently. The methodological quality of included studies was assessed using the Newcastle-Ottawa Scale for the observational studies. The summary estimates of the relationships of NSES with overweight, obesity and BMI statuses were calculated with random-effects meta-analysis models. Heterogeneity was assessed by Cochran's Q and I2 statistics. Subgroup analyses were done by age categories, continents, study designs and NSES measures. Publication bias was assessed by visual inspection of funnel plots and Egger's regression test. RESULT: A total of 21 observational studies, covering 1 244 438 individuals, were included in this meta-analysis. Low NSES, compared with high NSES, was found to be associated with a 31% higher odds of overweight (pooled OR 1.31, 95% CI 1.16 to 1.47, p<0.001), a 45% higher odds of obesity (pooled OR 1.45, 95% CI 1.21 to 1.74, p<0.001) and a 1.09 kg/m2 increase in mean BMI (pooled beta=1.09, 95% CI 0.67 to 1.50, p<0.001). CONCLUSION: NSES disparity might be contributing to the burden of overweight/obesity. Further studies are warranted, including whether addressing NSES disparity could reduce the risk of overweight/obesity. PROSPERO REGISTRATION NUMBER: CRD42017063889.

Biomedical and public health reviews and meta-analyses in Ethiopia had poor methodological quality: overview of evidence from 1970 to 2018.

OBJECTIVES: The aims of this overview are to assess the trend of narrative and systematic reviews in Ethiopia, examine their methodological quality, and suggest future directions for improvement. STUDY DESIGN AND SETTING: All narrative reviews and systematic reviews with or without a meta-analysis on topics associated with Ethiopia irrespective of the place of publication and authors' affiliation were included. The International Narrative Systematic Assessment for narrative reviews and A MeaSurement Tool to Assess Systematic Reviews for systematic reviews with or without a meta-analysis were used for quality appraisal. Fisher's exact test at the P-value threshold of 0.05 was used to investigate associated factors of methodological quality. RESULTS: Of 106 articles reviewed, 54 (50.9%) were narrative reviews, 17 (16%) were systematic reviews, and 35 (33.1%) were systematic reviews with meta-analyses. Among 48 systematic reviews with or without meta-analysis, only five (10.4%) registered their protocol, four (8.3%) justified the selection of the study design for inclusion, and none of them reported sources of funding for the primary studies. Overall, 55.3% of narrative reviews and 75% of systematic reviews with or without meta-analysis had poor methodological quality. CONCLUSIONS: Although publication rate of narrative and systematic reviews has risen in Ethiopia, half of the narrative reviews and three-quarters of the systematic reviews had poor methodological quality.

Dietary and non-dietary determinants of linear growth status of infants and young children in Ethiopia: Hierarchical regression analysis.

INTRODUCTION: Childhood growth faltering remains a major public health problem in developing countries. We aimed to identify the distal, underlying, and proximal dietary and non-dietary factors associated with length-for-age (LFA) of infants and young children in Ethiopia. METHODS: We used a nationally representative sample of 2,932 children aged 6-23 months from the Ethiopian demographic and health survey (EDHS) conducted in 2016. Hierarchical regression analysis was done to identify the factors associated with LFA. FINDINGS: Pastoral residence (adjusted ß (aß) = -0.56, 95%CI = -0.82, -0.31, P<0.001) and poorest household wealth category (aß = -0.57, 95%CI = -0.66, -0.48, P<0.001) were the basic factors negatively associated with LFA. Among underlying factors, maternal wasting (aß = -0.43, 95%CI = -0.58, -0.28, P<0.001), and unimproved toilet facility (aß = -0.48, 95%CI = -0.73, -0.23, P<0.001) were negatively associated with LFA. Proximal factors found positively associated with LFA were dietary diversity (aß = 0.09, 95%CI = 0.043, 0.136, P<0.001), meal frequency (aß = 0.04, 95%CI = 0.00, 0.08, P = 0.042), and vitamin A supplementation (aß = 0.16, 95%CI = 0.03, 0.29, P = 0.020). Male sex (aß = -0.26, 95%CI = -0.39, -0.14, P<0.001), age (aß = -0.12, 95%CI = -0.13, -0.10, P = 0.001), small birth size (aß = -0.45, 95%CI = -0.62, -0.29, P<0.001), and not currently breastfeeding (aß = -0.29, 95%CI = -0.47, -0.11, P = 0.003) were negatively associated with LFA. CONCLUSION: LFA was associated with various influences at distal, underlying, and proximal levels. A multi-pronged approach, addressing the various factors comprehensively, would represent an important consideration to promote linear growth in early childhood in Ethiopia.

Breast and complementary feeding in Ethiopia: new national evidence from systematic review and meta-analyses of studies in the past 10 years.

PURPOSE: The aim of this systematic review and meta-analysis was to provide a national estimate of breast and complementary feeding practices and its predictors in Ethiopia. METHODS: PubMed, SCOPUS, EMBASE, CINHAL, Web of Science and WHO Global Health Library electronic databases were searched for all available literature published until April 2018. Observational studies including cross-sectional, case-control and cohort studies were included. Newcastle-Ottawa Scale was used to assess the quality of studies. Heterogeneity of studies was quantified using Cochran's Q χ2 statistic and Higgins's method (I2). A meta-analysis using a weighted inverse variance method was performed. Subgroup analysis was carried out based on region and study area. RESULTS: In total, 70 studies that involved > 55,000 women from nine regions and two chartered cities in Ethiopia were included. The pooled national prevalence for timely initiation of breastfeeding (TIBF), exclusive breastfeeding (EBF) and timely initiation of complementary feeding was 66.5%, 60.1% and 62.5%, respectively. Guidance and counselling on breastfeeding, vaginal delivery and health institution delivery significantly increased the odds of TIBF and EBF. In addition, TIBF significantly associated with high EBF practice. Maternal occupational status significantly associated with low EBF practice, but not TIBF. CONCLUSIONS: Based on the WHO standard, the current breast and complementary feeding practice in Ethiopia is good and improving. Integrated intervention is still required for further improvement and minimizing the effect of occupational status.

Association between diabetes mellitus and multi-drug-resistant tuberculosis: evidence from a systematic review and meta-analysis.

BACKGROUND: Diabetes mellitus (DM) poses a significant risk for the development of active tuberculosis (TB) and complicates its treatment. However, there is inconclusive evidence on whether the TB-DM co-morbidity is associated with a higher risk of developing multi-drug-resistant tuberculosis (MDR-TB). The aim of this meta-analysis was to summarize available evidence on the association of DM and MDR-TB and to estimate a pooled effect measure. METHODS: PubMed, Excerpta Medica Database (EMBASE), Web of Science, World Health Organization (WHO), and Global Health Library database were searched for all studies published in English until July 2018 and that reported the association of DM and MDR-TB among TB patients. To assess study quality, we used the Newcastle-Ottawa Scale for cohort and case-control studies and the Agency for Healthcare Research and Quality tool for cross-sectional studies. We checked the between-study heterogeneity using the Cochrane Q chi-squared statistic and I2 and examined a potential publication bias by visual inspection of the funnel plot and Egger's regression test statistic. The random-effect model was fitted to estimate the summary effects, odds ratios (ORs), and 95% confidence interval (CIs) across studies. RESULTS: This meta-analysis of 24 observational studies from 15 different countries revealed that DM has a significant association with MDR-TB (OR = 1.97, 95% CI = 1.58-2.45, I2 = 38.2%, P value for heterogeneity = 0.031). The significant positive association remained irrespective of country income level, type of DM, how TB or DM was diagnosed, and design of primary studies. A stronger association was noted in a pooled estimate of studies which adjusted for at least one confounding factor, OR = 2.43, 95% CI 1.90 to 3.12. There was no significant publication bias detected. CONCLUSIONS: The results suggest that DM can significantly increase the odds of developing MDR-TB. Consequently, a more robust TB treatment and follow-up might be necessary for patients with DM. Efforts to control DM can have a substantial beneficial effect on TB outcomes, particularly in the case of MDR-TB. SYSTEMATIC REVIEW REGISTRATION: PROSPERO CRD42016045692 .

Determinants of heart rate variability in the general population: The Lifelines Cohort Study.

BACKGROUND: Heart rate variability (HRV) is an important marker of heart health, with low values reflecting reduced vagal control of the heart rhythm. OBJECTIVE: The purpose of this study was to investigate the extent to which a broad range of demographic (age, sex), lifestyle (physical activity, smoking, alcohol use), and psychosocial factors (stress, social well-being, neuroticism) explain individual differences in HRV in the general population. METHODS: Using baseline data of 10-second electrocardiograms from the Lifelines Cohort Study (n = 149,205; 58.7% female; mean age ± SD: 44.6 ± 13.2 years), we calculated the root mean square of successive differences (RMSSD) between adjacent interbeat intervals as an index of cardiac parasympathetic nervous system activity. We also calculated RMSSD adjusted for its dependency on heart rate (cRMSSD). The association of demographic, lifestyle, and psychosocial factors with RMSSD was assessed using hierarchical linear regression models adjusting for potential confounding effects of medication use, disease, and body mass index. RESULTS: HRV strongly declined with age and was consistently higher in women. These demographic factors together explained 17.4% of the variance in RMSSD and 21.9% in cRMSSD. Physical activity, alcohol use, and smoking showed some significant associations with RMSSD, but stress, social well-being, and neuroticism did not. Adding lifestyle and psychosocial factors to the model additionally explained <0.50% of the variance. CONCLUSION: Age and sex were the most important determinants in this very large general population cohort, explaining almost one-fifth of the individual differences in HRV. The additional contribution of lifestyle and psychosocial factors was negligible.

Health professional's knowledge and use of the partograph in public health institutions in eastern Ethiopia: a cross-sectional study.

BACKGROUND: The partograph is a vital tool for health professionals who need to be able to identify pathological labor. It is used to recognize complications in childbirth on time and to take appropriate actions. We aimed to assess the knowledge and utilization of the partograph and associated factors among health professionals at public health institutions in eastern Ethiopia. METHODS: An institution based cross-sectional quantitative study was carried out among health professionals who were working in public health institutions. Multistage sampling with proportional to size allocation was used to recruit a total of 441 study participants. Self-administered questionnaire was used to collect data in this study. Eight midwives were recruited and trained to facilitate the data collection activities. Data were entered into Epi data software and exported into SPSS (22.0) for analysis. Descriptive statistics, bivariate and multiple logistic regression were computed to determine proportions and significant association with knowledge and use of the partograph among health professionals. RESULTS: More than half of health professionals, 232(53.7%) had a good level of knowledge about the partograph. However, only 196(45.4%) of health professionals had fair knowledge of partograph. Nevertheless, the proportion of the partograph utilization to follow labor progress by health professionals was 92.6%. Working in the health center [AOR = 0.31, 95% CI: 0.20, 0.48], being a midwife [AOR = 2.80, 95% CI: 1.60, 5.60] and in-service training [AOR = 2.0, 95% CI: 1.22, 3.42] were significantly associated with good level of knowledge. Health professionals who had in-service training about the partograph [AOR = 3.10, 95% CI: 1.35, 4.98] and who had positive attitude about the partograph [AOR = 2.90, 95% CI: 1.30, 6.30] were significantly associated with utilization of the partograph. CONCLUSION: Only less than half of health professionals had fair knowledge about the partograph. Having in-service obstetric care training, type of health institutions and profession were significantly associated with knowledge of the partograph. Health professionals who had positive attitude towards use of the partograph were significantly associated with the partograph utilization. We suggest regular in-service training of health professionals can enhance their knowledge and utilization of the partograph.

SystEmatic review and meta-aNAlysis of infanT and young child feeding Practices (ENAT-P) in Ethiopia: protocol.

INTRODUCTION: Infant and young child feeding (IYCF) is the cornerstone of infant and child survival, healthy growth and development, healthy future generations and national development. In spite of the importance of optimal nutrition in low- and middle-income countries, there has been no review conducted in Ethiopia. Thus, the aim of this systematic review and meta-analysis is to estimate the national coverage and identify the associated factors of IYCF practices in Ethiopia. METHODS: PubMed, Scopus, EMBASE, CINHAL, EBSCO, Web of Science and WHO Global Health Library databases will be searched for all available publications from 1 January 2000 to 30 September 2017. All published studies on the timely initiation of breast feeding, exclusive breast feeding and timely initiation of complementary feeding practice in Ethiopia will be screened, selected and reviewed. Bibliographies of identified articles and grey literature will be hand-searched as well. Heterogeneity of studies will be quantified using Higgins's method where I2 statistic >80% indicates substantial heterogeneity. Funnel plots and Egger's regression test will be used to assess potential publication bias. The Newcastle-Ottawa Scale (NOS) will be used to assess the quality of evidence and risk of bias. Meta-analysis and meta-regression will be carried out to estimate the pooled national prevalence rate and an OR of each associated factor of IYCF practices. Narrative synthesis will be performed if meta-analysis is not feasible due to the substantial heterogeneity of studies. ETHICS AND DISSEMINATION: Ethical clearance is not required for this study because primary data will not be collected. The results of this systematic review and meta-analysis will be published in a peer-reviewed journal and presented at an (inter)national research symposium. SYSTEMATIC REVIEW REGISTRATION: This systematic review and meta-analysis has been registered with the International Prospective Register of Systematic Reviews (PROSPERO), registration number CRD42017056768.

Clinical Characteristics of Diabetic Ketoacidosis in Children with Newly Diagnosed Type 1 Diabetes in Addis Ababa, Ethiopia: A Cross-Sectional Study.

BACKGROUND: Diabetic ketoacidosis (DKA) is one of the most serious acute complications of type 1 diabetes (T1D) and the leading cause of morbidity and mortality in children with T1D. This study was aimed at assessing the prevalence and associated factors of DKA in children with newly diagnosed T1D in Addis Ababa. METHODS: A hospital based cross-sectional study was conducted in selected hospitals in Addis Ababa. Children below the age of 12 years with DKA who were admitted to the pediatric ward in the selected hospitals between January 2009 and December 2014 and the residence of Addis Ababa were included. DKA was defined as children below the age of 12 years who have blood glucose level ≥250mg/dl, ketonuria, and ketonemia and diagnosed being T1D patient for the first time. Descriptive statistics was performed using frequency distribution, mean, median, tables, and graphs. Logistic regression analysis was used to identify independent factors associated with the prevalence of DKA in children with newly diagnosed T1D. RESULTS: Of 395 DKA patients who were hospitalized during the five-year period, 142(35.8%) presented with DKA at first diagnosis of diabetes. On the other hand 253 (64.2%) children with DKA had longstanding T1D. Independent factors associated with DKA include: Age category 2-4.49years, 7-9.49 years and ≥9.5years (Adjusted odd ratio (AOR) = 3.14[1.21,8.06]), 3.44(1.39,8.49) and 4.02(1.68,9.60), respectively); parents' knowledge on the sign and symptoms of DKA (AOR = 0.51[0.27, 0.95]); sign and symptoms of DKA before the onset of DKA (AOR = 0.35[0.21, 0.59]) and infection prior to DKA onset (AOR = 3.45[1.97, 6.04]). CONCLUSIONS: The overall proportion of children diagnosed with DKA and new onset of T1D in Addis Ababa was high. In particular, children between 9-12 years of age and children whose parents did not know the sign and symptoms of DKA had a high risk of DKA at primary diagnosis of T1D.

Association between diabetes mellitus and multi-drug-resistant tuberculosis: a protocol for a systematic review and meta-analysis.

INTRODUCTION: Multi-drug-resistant tuberculosis (MDR-TB) has emerged as a challenge to global tuberculosis (TB) control and remains a major public health concern in many countries. Diabetes mellitus (DM) is an increasingly recognized comorbidity that can both accelerate TB disease and complicate its treatment. The aim of this study is to summarize available evidence on the association of DM and MDR-TB among TB patients and to provide a pooled estimate of risks. METHODS: All studies published in English before October 2016 will be searched using comprehensive search strings through PubMed, EMBASE, Web of Science, and WHO Global Health Library databases which have reported the association of DM and MDR-TB in adults with TB (age > =15). Two authors will independently collect detailed information using structured data abstraction form. The quality of studies will be checked using Newcastle-Ottawa Scale for cohort and case-control studies and the Agency for Healthcare Research and Quality tool for cross-sectional studies. Heterogeneity between included studies will be assessed using the I2 statistic. We will check potential publication bias by visual inspection of the funnel plot and Egger's regression test statistic. We will use the random effects model to compute a pooled estimate. DISCUSSION: Increases in the burden of non-communicable diseases and aging populations are changing the importance of different risk factors for TB, and the profile of comorbidities and clinical challenges for people with TB. Although classic risk factors and comorbidities such as overcrowding, under-nutrition, silicosis, and HIV infection are crucial to address, chronic conditions like diabetes are important factors that impair host defenses against TB. Thus, undertaking integrated multifaceted approach is remarkably necessary for reducing the burden of DM and successful TB treatment outcome.

Comorbidity of depression and diabetes: an application of biopsychosocial model.

BACKGROUND: Type 2 diabetes (T2D) is one of the most psychologically demanding chronic medical illness in adult. Comorbidity between diabetes and depression is quite common, but most studies were based on developed country sample. Limited data exists to document biopsychosocial predictors of depressive symptoms in Ethiopian patients. Therefore, the aim of the study was to describe the association of depressive symptoms and T2D and explore the potential underlying associated biopsychosocial risk factors. METHODS: Institution based cross-sectional study was conducted on 276 patient with T2D at diabetic clinic, Black Lion General Specialized Hospital in Ethiopia. Patients were selected using systematic random sampling technique. Depressive symptoms score, which constructed from a validated nine-item Patient Health Questionnaire (PHQ-9), was an outcome variable. Finally, significant associated factors were identified using multiple linear regression analysis with backward elimination procedure. Statistical Package for Social Science (SPSS) version 22.0 (IBM SPSS Corp.) was used to perform all analysis. RESULTS: Total of 264 patient data was analyzed with 95.7% response rate. Patients mean (SD) current age and age at diagnosis was 55.9 (10.9) and 43.9 (10.9) years, respectively. Patients waist circumference (mean ± SD) was 98.9 ± 11.1 cm. The average PHQ-9 score was 4.9 (SD 4.1) and fasting blood glucose was 166.4 (SD 73.2). Marital status (divorced), occupation (housewife), diabetic complication (nephropathy), negative life event in the last six months, and poor social support significantly associated with increased mean PHQ-9 score after adjustment for covariates. Whereas not fearing diabetic-related complication and death significantly lower mean PHQ-9 score. CONCLUSION: Biopsychosocial variables including marital status, negative life event in the last 6 months, occupation, diabetic complication, and poor social support significantly increase average depressive symptoms score. Evidence-based intervention focusing on these identified biopsychosocial factors are necessary to prevent the development of depressive symptoms.

Treatment outcome and factors affecting time to recovery in children with severe acute malnutrition treated at outpatient therapeutic care program.

BACKGROUND: The outpatient therapeutic care program (OTP) of children with severe acute malnutrition (SAM) has been decentralized to health post level in Ethiopia since 2008-2009. However, there is a lack of evidence regarding treatment outcomes and factors related to the duration of stay on treatment after its decentralization to health post level. OBJECTIVE: This study was aimed to assess treatment outcome and factors affecting time to recovery in children with SAM treated at OTP. DESIGN: Health facility-based retrospective cohort study was conducted using data from 348 patient cards. The outcome variable was time to recovery. Descriptive analysis was done using percentages for categorical data and mean/median for continuous variables. A robust method of analyzing time to event data, the Cox proportional-hazard regression, was used. All statistical tests in this study are declared significant at p<0.05. RESULT: 89.1% of children with kwashiorkor and 69.4% of children with marasmus were recovered. Of the total children studied, 22% were readmitted cases. The median time of recovery was 35 days for children with kwashiorkor and 49 days for children with marasmus. Children older than 3 years were 33% less likely to achieve nutritional recovery [adjusted hazard ratio, AHR=0.67, 95% confidence interval, CI (0.46, 0.97)]. Similarly, marasmic children stayed longer on treatment [AHR=0.42, 95% CI (0.32, 0.56)]. However, children who gained Mid-Upper Arm Circumference (MUAC) ≥ 0.24 mm/day were 59% more likely to recover faster [AHR=1.59, 95% CI (1.23, 2.06)]. CONCLUSIONS: Close monitoring of weight and MUAC gain to assess nutritional improvement with due emphasis given to children with lower admission weight, children of age 3 years and above and marasmic children will have a positive effect on treatment duration and outcome.
