The effect of possible mediators on the association between chewing khat during pregnancy and fetal growth and newborn size at birth in Eastern Ethiopia

INTRODUCTION

Restriction in the growth of the fetus is a leading cause of stillbirth, neonatal mortality, and short- and long-term morbidity. Documented existing scientific evidence have shown the effects of maternal drugs use, alcohol drinking, tobacco smoking, cocaine use and heroin use on fetal growth restriction. However, data is lacking on the effects of khat chewing during pregnancy on fetal growth status and newborn size at birth. Therefore, the aim of the present study was to measure the effect of chewing khat during pregnancy on fetal growth and size at birth in eastern Ethiopia.

METHOD

A cohort study was conducted in selected health institutions in eastern Ethiopia. All pregnant women fulfilled the eligibility criteria in the selected health institutions was the source population. The calculated sample size of exposed and unexposed groups included in the study, in total, was 344. Data collection was performed prospectively by interviewers administered questionnaires, and anthropometric, clinical and ultrasound measurements. Data was analyzed using SPSS version 27 and STATA version 16 software. The survival analysis (cox proportional hazards model) and generalized linear model (GLM) for the binomial family analysis were performed to estimate the crude and adjusted relative risk and attributable risk (AR) with corresponding 95% CI of chewing khat on fetal growth restriction. The mediation effect has been examined through Generalized Structural Equation Modeling (GSEM) analysis using the Stata 'gsem' command. Statistically significant association was declared at p-value less than 5%.

RESULTS

In the present study, the incidence of fetal growth restriction (FGR) among the study cohorts was 95 (29.7%); of this, 81 (85.3%) were among khat chewer cohorts. The relative risk of fetal growth restriction among khat chewer cohort mothers was significantly higher (aRR = 4.32; 95%CI 2.62-7.12). Moreover, the incidence of small for gestational age at birth among the present study cohorts was 100 (31.3%); 84 (84%) were from khat chewer cohorts' deliveries. More importantly, in the present study, 98.95% of the ultrasound-identified fetuses with FGR were found to be SGA at birth. Hence, in the current study, FGR was highly associated with SGA at birth. In additional analysis, the regression coefficient of khat chewing during pregnancy on fetal growth restriction has been decreased in size from path o, β = 0.43, p < 0.001 to path o', β = 0.32, p < 0.001, after adjusting for gestational hypertension and maternal anemia.

CONCLUSION

In sum, the present study showed khat chewing during pregnancy is not simply affected the mothers, but it also affected the unborn fetuses. Therefore, the health workers as well as the local community and religious leaders should give high emphasis on provision of health education regarding the damage of chewing khat by pregnant mothers, with especial focus of the effects on their fetuses.

Magnitude and associated factors of chewing khat during pregnancy in Eastern Ethiopia, 2022: a mixed method cross-sectional study

Introduction

khat (Catha edulis Forsk), is an evergreen flowering tree or shrub widely produced and consumed in East Africa and the Arabian Peninsula. In Ethiopia, it is largely produced, freely marketed and consumed by almost all segments of the population. This is more pronounced in the Eastern part of the country. However, there exists little scientific information on the level and associated factors of khat use among pregnant women in Ethiopia, despite a few available evidences indicated its adverse effect on pregnancy outcomes. Moreover, the perceived reasons for chewing khat during pregnancy were not yet explored qualitatively to triangulate the quantitative findings. Hence, the aim of the present study was to determine the magnitude and associated factors of chewing khat during pregnancy in Eastern Ethiopia, 2022, in a Mixed Method study approach.

Methods

an institution-based cross-sectional study was conducted from August 1st to 14th, 2022 using both quantitative and qualitative methods. Two hundred forty-two pregnant mothers on Antenatal care (ANC) were included in the study. Moreover, 18 purposively selected pregnant mothers on ANC were also considered for qualitative data. Analysis of quantitative data was performed on Statistical Package for the Social Sciences (SPSS) version 27 and thematic framework analysis was performed for qualitative data. Univariable and multivariable logistic regression analysis was performed to identify variables which are significantly associated with khat chewing during pregnancy and to estimate the variable's crude and adjusted odds' ratio with corresponding 95% CI. The statistically significant association was declared at p-value of less than 5.

Results

the overall magnitude of chewing khat during pregnancy in the present study was 27.4% (95% CI: 22.2-33.0). Variables which significantly associated with chewing khat during pregnancy in this study were being >26 years [adjusted odds' ratio (AOR)=2.81 95% CI: 1.19-6.59], being a rural resident (AOR=2.82 95% CI: 1.19-6.69), being illiterate (AOR=4.31 95% CI: 1.02-18.20), participants having chewer husbands (AOR=3.51 95% CI: 1.33-9.24) and respondents having other chewer family members (AOR=3.05 95% CI: 1.19-7.77). In addition, the perceived reasons for chewing khat explored through in-depth interviews were for socialization, to obey tradition, to be happy with friends, husbands and families, to be free from tensioned situations, to be effective in performing daily activities, and due to lack of knowledge of its harm.

Conclusion

in the present study, a relatively higher proportion of mothers chewed khat during their current pregnancy. Being older age, living in rural areas, being illiterate, having khat chewer husbands and other family members were statistically significant variables associated with khat chewing during pregnancy. Moreover, pregnant mothers are practicing chewing of khat in the current study area due to deep-rooted sociocultural issues. Hence, creation of awareness on possible harm of chewing khat during pregnancy especially for those found to be at significantly increased risk of consumption in this study is highly recommended during their antenatal care visits. In addition, creation of awareness out of health institutions, at household and community level, is highly recommended, probably using community volunteers (health development armies) in the present study area. At last, we highly also recommend the local government and religious leaders to work on how to stop the chewing practice especially during pregnancy. For example, the local government and religious leaders can work on averting consideration of chewing by the community as culturally accepted practices.

A multicenter study on practices and related factors of traditional medicinal plant use during pregnancy among women receiving antenatal care in East Gojjam Zone, Northwest Ethiopia

Background

Little is known about the practice of traditional medicinal plant use, especially during pregnancy in Ethiopia. Moreover, there has been no previous studies conducted on practices and related factors of medicinal plant use among pregnant women in Gojjam, northwest Ethiopia.

Methods

A multicentered facility-based cross-sectional study was conducted from July 1 to 30 2021. A total of 423 pregnant mothers receiving antenatal care were included in this study. To recruit study participants, multistage sampling techniques were used. Data were collected using a semi-structured interviewer-administered questionnaire. SPSS version 20.0 statistical package was used for statistical analysis. Univariable and multivariable logistic regression analysis was performed to identify factors related to the medicinal plants' utilization status in pregnant mothers. The study results were presented in both descriptive statistics (percents, tables, graphs, mean, and dispersion measurements like standard deviation) and inferential statistics (odds ratio).

Results

The magnitude of traditional medicinal plants' utilization during pregnancy was 47.7% (95%CI: 42.8-52.8%). Pregnant mothers residing in rural areas [Adjusted Odds Ratio (AOR) = 3.13; 95% Confidence Interval (CI):1.53, 6.41], who are illiterate (AOR = 2.99; 95%CI:1.097, 8.17), have illiterate husbands (AOR = 3.08; 95%CI:1.29, 7.33), married farmers (AOR = 4.92; 95%CI:1.87, 12.94), married merchants (AOR = 0.27; 95%CI:0.09, 0.78), have a divorced and widowed marital status (AOR = 3.93; 95%CI:1.25, 12.395), have low antenatal care visits (AOR = 4.76; 95%CI:1.93, 11.74), substance use history (AOR = 7.21; 95%CI:3.49, 14.9), and used medicinal plants in previous pregnancy (AOR = 4.06; 95%CI:2.03, 8.13) had statistically significant association with medicinal plant use during current pregnancy.

Conclusions

The present study revealed that a relatively large number of mothers used medicinal plants of various types during their current pregnancy. Area of residence, maternal educational status, husband's education level, husband's occupation status, marital status, number of antenatal care visits, use of medicinal plants in previous pregnancies, and substance use history were among the factors which were significantly associated with the use of traditional medicinal plants during the current pregnancy. Overall, the current finding provides scientific evidence useful for health sector leaders and healthcare professionals on the utilization of unprescribed medicinal plants during pregnancy and the factors associated with the utilization of the plants. Hence, they may consider creating awareness and providing advice on the careful use of unprescribed medicinal plants among pregnant mothers, especially those residing in rural areas, who are illiterate, who have divorced and widowed marital status, and who have a previous history of herbal and substance use. This is because using traditional medicines without prior discussion with a healthcare expert may harm pregnant mothers and their unborn child, as the safety of the utilized plants in the current study area is not scientifically proven. Prospective studies which need to confirm the safety of the plants used are recommended mainly in the present study area.

Effects of dietary diversification during pregnancy on birth outcomes in east Gojjam, northwest Ethiopia: A prospective cohort study

Introduction

Adequate nutrient intake during pregnancy is an important key factor affecting fetal growth and birth outcomes, as well as maternal health, as demonstrated by experimental animal studies. However, the few human studies available, especially those conducted in the least developed countries (LDCs), are much less consistent. Therefore, this study aimed to investigate the association between dietary diversification during pregnancy and birth outcomes in Gojjam, Ethiopia.

Methodology

A facility-based prospective cohort study was conducted on 416 pregnant mothers (exposed and non-exposed) from December 2019 to January 2020. Information about the Women's Dietary Diversity Score (WDDS) was collected using the Food and Agricultural Organization's guidelines. Data were collected through interviewer-administered questionnaires and measurements. Log-binomial regression analysis was performed to estimate the relative risk of adverse birth outcomes. Energy, macronutrient, and micronutrient amounts were calculated using the nutrition survey software version 2007. The differences between groups were noticed using analysis of variance. Eta squared was estimated in the current study.

Results

The overall magnitude of low birth weight, preterm birth, and stillbirth in the study area, respectively, was 41%, 38%, and 4%. After adjustment for baseline characteristics, this study revealed that pregnant women in the inadequate WDDS group were at increased risk of LBW (ARR = 6.4; 95% CI: 3.4, 12) and PTD (ARR = 6.3; 95% CI: 3.3, 11.95) as compared with their counterparts but no difference in the occurrence of stillbirth (ARR = 1.08; 95% CI: 0.20, 5.79).

Conclusion

Overall, this study found a large magnitude of low birth weight and preterm birth. Inadequate intake of dietary diversity during pregnancy significantly increased the rate of low birth weight and preterm birth. Thus, we recommend the concerned body to work on improving the feeding practices of pregnant mothers in the study area.

The association between folic acid supplementation and congenital heart defects: Systematic review and meta-analysis

Introduction:

Various trial and epidemiological studies consistently documented the association between maternal folic acid supplementations and neural tube defects. However, existing literatures revealed inconclusive findings about maternal periconceptional folic acid supplementations and the risk of congenital heart defects. Thus, the current systematic review and meta-analysis was aimed to estimate the pooled association between maternal periconceptional folic acid supplementations and congenital heart defects.

Methods:

Electronic searches of PubMed, Web of Science/Scopus, Cochrane library and Google Scholar databases were conducted to access the required studies published up to March 2021. Predetermined eligibility criteria were used for study selections. Data extraction were independently done on excel. STATA version 14 software was used to calculate the pooled effect size with 95% confidence intervals (95% CI) of maternal periconceptional folic acid supplementations on congenital heart defects using the DerSimonian and Laird random effects meta-analysis (random effects model). Statistical heterogeneity was checked using the Cochran Q test (chi-squared statistic), I2 statistic, and by visual inspection of the funnel plot.

Results:

A total of 37 studies of case–control, cohort and randomized controlled trial in nature were included in the review. The finding of the present systematic review and meta-analysis indicated that periconceptional folic acid supplementation significantly decreases the risk of congenital heart defects (risk ratio (RR), 0.79; CI, 0.71, 0.89). Both Cochrane Q test statistic (χ2 = 19.33, p = 0.962) and I2 test statistic (I2 = 0.0%, p = 0.962) did not reveal statistically significant heterogeneity among included studies. In this meta-analysis, traditional funnel plot, Begg’s funnel plot, Egger’s weighted regression (p = 0.13) as well as Begg’s rank correlation statistic (p = 0.676) revealed no evidence of publication bias.

Conclusion:

The present systematic review and meta-analysis found that maternal periconception folic acid supplementation was significantly associated with the risk of congenital heart defects. The risk of congenital heart defects was significantly reduced by 21% among those children of mothers who use periconceptional folic acid supplementations in high-income countries. We recommend that a large prospective study be conducted to investigate the association between maternal periconceptional folic acid supplementation and occurrence of congenital heart defect of various types, especially in the developing countries.

Prevalence of diabetes mellitus among tuberculosis patients in Sub-Saharan Africa: a systematic review and meta-analysis of observational studies

BACKGROUND

Tuberculosis and diabetes mellitus are significant global public health challenges. In Sub-Saharan Africa, study findings regarding prevalence of diabetes mellitus amongst tuberculosis patients have been inconsistent and highly variable. Therefore, this systematic review and meta-analysis estimates the overall prevalence of diabetes mellitus among tuberculosis patients in Sub-Saharan Africa.

METHODS

Four international databases (PubMed, Google Scholar, Science Direct and Cochrane Library) were systematically searched. We included all observational studies reporting the prevalence of DM among TB patients in Sub-Saharan Africa. All necessary data for this review were extracted using a standardized data extraction format by two authors (CT and AA1). STATA Version 14 statistical software was employed to conduct meta-analysis. The Cochrane Q test statistics and I2 test were used to assess the heterogeneity of the studies. Finally, a random effects meta-analysis model was computed to estimate the pooled prevalence of diabetes mellitus in TB patients. Besides, subgroup analysis was done based on different factors.

RESULTS

In the meta-analysis, sixteen studies fulfilled the inclusion criteria and were included. The findings of these 16 studies revealed that the pooled prevalence of diabetes mellitus among tuberculosis patients in Sub-Saharan Africa was 9.0% (95% CI: 6.0, 12.0%). The highest prevalence of diabetes mellitus among tuberculosis patients was found in Nigeria (15%), followed by Tanzania (11%), and then Ethiopia (10%). Besides, the prevalence of diabetes mellitus among HIV infected TB patients was (8.9%) which is slightly higher than HIV uninfected (7.7%) TB patients.

CONCLUSION

Diabetes mellitus among tuberculosis patients in Sub-Saharan Africa was significantly high. Moreover, this study found that there was a high prevalence of DM among HIV infected than uninfected TB patients. It is strongly recommended to screen for DM among TB patients and special emphasis should be given for early screening of DM among TB/HIV co-infected patients.

The effect of antenatal care follow-up on neonatal health outcomes: a systematic review and meta-analysis

Background

Neonatal mortality is one of the major public health problems throughout the world and most notably in developing countries. There exist inconclusive findings on the effect of antenatal care visits on neonatal death worldwide. Thus, the aim of this systematic review and meta-analysis was to reveal the pooled effect of antenatal care visits on neonatal death.

Methods

The present systematic review and meta-analysis was performed using published literature, which was accessed from national and international databases such as, Medline/PubMed, EMBASE, CINAHL, Cochrane Central library, Google Scholar, and HINARI. STATA/SE for windows version 13 software was used to calculate the pooled effect size with 95% confidence intervals (95% CI) of maternal antenatal care visits on neonatal death using the DerSimonian and Laird random effects meta-analysis (random effects model), and results were displayed using forest plot. Statistical heterogeneity was checked using the Cochran Q test (chi-squared statistic) and I² test statistic and by visual examination of the forest plot.

Results

A total of 18 studies, which fulfilled the inclusion criteria, were included in the present systematic review and meta-analysis. The finding of the present systematic review and meta-analysis revealed that antenatal care visits decrease the risk of neonatal mortality [pooled effect size 0.66 (95% CI, 0.54, 0.80)]. Cochrane Q test (P < 0.001) revealed no significant heterogeneity among included studies, but I² statistic revealed sizeable heterogeneity up to 80.5% (I² = 80.5%). In the present meta-analysis traditional funnel plot, Egger’s weighted regression (P = 0.48) as well as Begg’s rank correlation statistic (P = 0.47) revealed no evidence of publication bias.

Conclusions

The present systematic review and meta-analysis revealed that antenatal care visits were significantly associated with lower rates of neonatal death. The risk of neonatal death was significantly reduced by 34% among newborns delivered from mothers who had antenatal care visits. Thus, visiting antenatal care clinics during pregnancy is strongly recommended especially in resource-limited settings like countries of sub-Saharan Africa.

Household latrine utilization and its association with educational status of household heads in Ethiopia: a systematic review and meta-analysis

BACKGROUND

Ethiopia has been experiencing a high prevalence of communicable diseases, which resulted in high morbidity, mortality, and hospital admission rates. One of the highest contributing factors for this is lower level of latrine utilization. There had been significantly varying finding reports with regard to the level of latrine utilization and its association with education level from different pocket studies in the country. Therefore, this systematic review and meta-analysis was aimed to estimate the pooled prevalence of household latrine utilization and its association with education status of household heads, in Ethiopia using available studies.

METHODS

This systematic review and meta-analysis was conducted using available data from the international databases, including PubMed, Google Scholar, Science direct, Cochrane library and unpublished reports. All observational studies reporting the prevalence of latrine utilization in Ethiopia were included. Four authors independently extracted all necessary data using a standardized data extraction format. STATA 13 statistical software was used to analyze the data. The Cochrane Q test statistics and I2 test were used to assess the heterogeneity between the studies. A random effect model was computed to estimate the pooled level of latrine utilization in Ethiopia. In addition, the association between latrine utilization and the educational level of the users was analyzed.

RESULTS

After reviewing of 1608 studies, 17 studies were finally included in our meta-analysis. The result of 16 studies revealed that the pooled prevalence of latrine utilization level in Ethiopia was 50.02% (95%CI: 40.23, 59.81%). The highest level (67.4%) of latrine utilization was reported from Southern Nations Nationality and People regional state, followed by Amhara regional state (50.1%). Participants who completed their high school and above education were more likely (OR: 1.79, 95%CI: 1.05, 3.05) to utilize latrine compared to those who did not attend formal education.

CONCLUSION

In Ethiopia, only half of the households utilize latrine and the level of utilization has significant association with educational status.

Undiagnosed Diabetes Mellitus and Related Factors in East Gojjam (NW Ethiopia) in 2016: A Community-Based Study

Introduction

Currently, diabetes is the second most common non-communicable disease (NCD) in Ethiopia. Its burden is 4.8% in this country, even though three quarter of its population live with undiagnosed diabetes mellitus (DM), which causes complications like heart failure, blood vessels, eyes, kidneys and nerves damages. Early detection of DM is vital for a timely intervention to prevent these life threatening complications. The aim of this study was to assess the prevalence of undiagnosed DM and related factors in East Gojjam, North West Ethiopia, in 2016.

Materials and methods

A community-based cross-sectional study was conducted among 757 individuals in East Gojjam from June to September 2016. The sampled population was selected using multi-stage cluster sampling method. Basic data were collected in Amharic (local language) and a pretested interviewer administered the questionnaire. Peripheral blood samples were collected by puncturing the ring finger in order to measure fasting blood glucose. Univarite and multivariate logistic regressions analysis were performed using Statistical Package for Social Sciences (SPSS) software version 20.0.

Results

The percentage of undiagnosed DM in the study area was 11.5% (95%CI=9.2, 13.7). The prevalence was 11.3% among male vs. 11.8% among female; 13.4% in urban areas vs. 10.3% in rural areas. The occurrence of undiagnosed DM was mainly associated with older age (AOR=5.99, 95%CI=1.54, 23.24), family history of diabetes (AOR=9.86, 95%CI=4.25, 22.89), history of gestational diabetes (AOR=3.01, 95%CI=1.17, 8.39) and sedentary behaviour >4 hours per day (AOR=2.13, 95%CI=1.04, 4.34). Being non-smoker (AOR=0.05, 95%CI=0.01, 0.17) and unmarried (AOR=0.09, 95%CI=0.02, 0.42) were also predictive characteristics for undiagnosed DM in the study area.

Conclusions

In conclusion, this study revealed a relatively high prevalence of undiagnosed DM in the study area. The occurrence of undiagnosed DM was significantly higher when associated with the age of the participants, their marital status, history of hypertension, diabetes family history, history of gestational diabetes mellitus, current smoking practices and sedentary behaviour. Thus, efforts have to be made, particularly by the individuals involved in health practice, to early detect the disease and thereby initiate a suitable therapeutic service, before complications arise
