Effects of psychosocial work factors on preterm birth: systematic review and meta-analysis

OBJECTIVES

Preterm birth is one of the global public health issues that result in high rates of infant mortality and long-term health complications. We sought to explore the association between psychosocial work factors and preterm birth.

STUDY DESIGN

Systematic review and meta-analysis.

METHODS

This systematic review and meta-analysis searched relevant literature from electronic databases to explore the association between psychosocial work factors and preterm birth. The methodological quality of the included studies was evaluated through the Joanna Briggs Institute's critical appraisal method. We performed a meta-analysis using a random-effects model to combine odds ratios (ORs) from studies with similar definitions of exposure and outcome. The quality of the evidence was evaluated using the GRADE (Grade of recommendation, Assessment, development, and Evaluation) method to assess.

RESULTS

Ten studies were included, with a total of 92,815 participants. Moderate evidence indicated a positive association between high psychosocial job strain and preterm birth. The result from the meta-analysis supported the statistical significance of this relationship (OR 1.32 [95% CI (1.22-1.44)]).

CONCLUSIONS

Pregnant women who experience high levels of psychosocial job strain are more likely to give birth prematurely. In order to decrease this risk, employers should prioritise creating supportive work environments, government bodies should enact protective policies and regulations, and clinicians should give advice to pregnant working women. Pregnant women should be aware of the risk of preterm birth from psychosocial work factors.

Health professionals' knowledge on vaccine cold chain management and associated factors in Ethiopia: Systematic review and meta-analysis

BACKGROUND

Vaccines are playing a great role in prevention of many infectious diseases worldwide. Health professionals' knowledge towards vaccine cold chain management is an essential element of maintaining vaccine's potency at shelf and during transportation. Studies on health professionals' knowledge on vaccine cold chain management system and associated factors in Ethiopia have inconclusive findings. This systematic review and meta-analysis is aimed to produce the overall level of health professionals' knowledge on vaccine cold chain management system and to identify its associated factors in Ethiopia.

METHODS

Systematic review and meta-analysis was conducted on health professionals' knowledge on vaccine cold chain management in Ethiopia. It is registered under PROSPERO website with registration number CRD42023391627. Literature search was made on international data bases using medical subject heading and key words. Data were extracted using Microsoft excel and imported to STATA version 17 for analysis. Heterogeneity was checked using Cochrane Q test and I2 statistics. Weighted Inverse variance random effect model was used to estimate the pooled level of health professionals' knowledge on vaccine cold chain management. Publication bias was checked using funnel plot and using Egger's test.

RESULTS

A total of nine studies were included in the review. The pooled health professionals' good knowledge on vaccine cold chain management in Ethiopia is 49.92% with 95% CI (48.06-51.79). Having five years or more experience AOR 2.27 95% CI (1.72-2.99), being nurse AOR 3.03 95% CI (1.47-6.27), received on job training AOR 6.64 95% CI (4.60-9.57), EPI guideline available at facility AOR 2.46 95% CI (1.75.-3.48) are factors positively associated with health professionals' knowledge on vaccine cold chain management in Ethiopia.

CONCLUSION

The pooled prevalence of good knowledge on vaccine cold chain management among health professionals is much lower than the expected level. There is a need to plan on job trainings for all vaccine handlers and other health professionals supposed to work on vaccination program.

Willingness to vaccinate their daughters against human papillomavirus among parents of Ethiopian adolescent girls: a systematic review and meta-analysis

INTRODUCTION

HPV vaccination of adolescent girls is the primary strategy for cervical cancer prevention but in Ethiopia, it lacks emphasis. Despite different studies done and found a highly variable level of parents' willingness to vaccinate their daughter for HPV; however, there was no summarized evidence of parents' willingness as a nation. Thus this systematic review and meta-analysis aimed to assess the pooled prevalence of parents' willingness to HPV vaccination of their daughters and associated factors in Ethiopia.

METHODS

A systematic review and meta-analysis were conducted using PRISMA guidelines. Comprehensive literature was searched in international databases. A weighted inverse variance random effect model was used to estimate pooled prevalence. Cochrane Q test and I2 statistics were computed to assess heterogeneity. Funnel plot and Eggers test were done to assess publication bias. Review manager software was used to identify determinants of parents' willingness.

RESULTS

Overall, 172 articles were retrieved and finally 7 articles were included in this review. The pooled prevalence of parents' willingness to HPV vaccination of their daughters was 71.82% (95% CI 57.73-85.91%). Knowledge about HPV vaccination (AOR = 2.80, 95% CI (2.10-3.73)), attitude (AOR = 4.93, 95% CI (3.48-6.99)), educational status (AOR = 2.19, 95% CI 1.54-3.10) and income (AOR = 3.13, 95% CI 1.96-5.02)) were significantly associated with parents' willingness.

CONCLUSIONS

Parents' willingness to HPV vaccination of their daughters in Ethiopia was low. Knowledge, attitude, educational status, and income were positively associated with parents' willingness. Therefore, policymakers and program planners should target those important stakeholders (parents) in increasing their awareness and changing their attitude to enhance their vaccine acceptance specifically focusing on those who are lower in economic and educational status so as to prevent the lethal cervical cancer.

Maternal Occupational Risk Factors and Preterm Birth: A Systematic Review and Meta-Analysis

Objective: This systematic review and meta-analysis aimed to summarize the evidence on the relationship between physical occupational risks (high physical workload, long working hours, shift work, whole-body vibrations, prolonged standing, and heavy lifting) and preterm birth. Methods: A systematic review and meta-analysis was conducted across six databases to investigate the relationship between physical occupational risks and preterm birth. Result: A comprehensive analysis of 37 studies with varying sample sizes found moderate evidence of positive associations between high physical workload, long working hours, shift work, whole-body vibration, and preterm birth. Meta-analysis showed a 44% higher risk (OR 1.44, 95% CI 1.25-1.66) for preterm birth with long working hours and a 63% higher risk (OR 1.63, 95% CI 1.03-2.58) with shift work. Conclusion: Pregnant women in physically demanding jobs, those working long hours or on shifts, and those exposed to whole-body vibration have an increased risk of preterm birth. Employers should establish supportive workplaces, policymakers implement protective measures, healthcare providers conduct screenings, and pregnant women must stay informed and mitigate these job-related risks.

Maternal occupational risk factors and preterm birth: Protocol for a systematic review and meta-analysis

INTRODUCTION

Preterm birth, which accounts for 33.1% of neonatal death globally, is the main cause of under-five mortality. A growing number of studies indicate that occupational risk factors during pregnancy are linked to an increased likelihood of poor pregnancy outcomes. The effect of physical occupational risks on preterm birth has received very little attention, and previous reviews have produced inconclusive results. This systematic review aims to update the evidence on the relationship between maternal physical occupational risks and preterm birth.

METHOD AND ANALYSIS

We will search electronic databases including Ovid Medline, Embase, Emcare, CINAHL, Scopus, and Web of science to find peer-reviewed studies examining the relationship between six common maternal physical occupational risks (heavy lifting, prolonged standing, heavy physical exertion, long working hours, shift work, and whole-body vibrations) and preterm birth. Articles published in English after 1 January 2000 will be included without geographic restrictions. Two reviewers will screen titles and abstracts independently, and then select full-text articles that meet inclusion criteria. Methodological quality of the included studies will be evaluated using the Joanna Briggs Institute (JBI) critical appraisal method. The quality of evidence across each exposure and the outcome of interest will be examined by using the GRADE (Grade of Recommendations, Assessment, Development, Evaluation) method. Accordingly, a high level of evidence will lead to "strong recommendations". A moderate level of evidence will lead to "practice considerations". For all evidence levels below moderate, the message will be "not enough evidence from the scientific literature to guide policymakers, clinicians, and patients. If data permits, a meta-analysis will be conducted using Stata Software. In case where meta-analysis is not possible, we will perform a formal narrative synthesis.

DISCUSSION AND CONCLUSION

Evidence suggests that preterm birth is linked to a number of maternal occupational risk factors. This systematic review will update, compile, and critically review the evidence on the effect of maternal physical occupational risk on preterm birth. This systematic review will provide guidance to support decision-makers including maternal and child health services, other health care providers, and government policy agencies.

Effects of Scaling Up Family Planning on Maternal Survival in Ethiopia: Spectrum Modeling

Background

Ethiopia has made great strides on under-five and maternal mortality reduction as demonstrated by achieving the millennium development target of child mortality reduction by the start of 2015. According to a recent demographic and health survey report, Ethiopia has a 67 per 1000 under-five mortality rate and a 412 per 100,000 live births maternal mortality ratio. The current trend of maternal and child mortality reduction is not enough to meet sustainable development goal three (SDG3) of maternal and child mortality reduction target which is set to reduce the maternal mortality ratio to below 70/100,000 live births in all countries. This paper aimed to model the effect of scaling up family planning on pregnancies, live births, stillbirths, abortions and maternal mortality in Ethiopia.

Methods

We used the Spectrum software package to model the impact of family planning on maternal survival and other maternal health metrics. Spectrum has different modules consisting of demproj module (demographic projection), famplan module (family planning), LiST (life saved tool), and AIM (aids impact model). We used Demproj, Famplan and LiST modules for this particular paper. Baseline national data were taken from findings of the Ethiopian demographic and health survey 2016, and World Bank and World Health Organization country specific reports.

Results

Total fertility rate will decline to 2.3 children per women by the year 2030 when contraceptive prevalence is scaled up by 2% annually from 2016 to 2030. As a result of continuous scaling up of contraceptive use, around 3.17 million unintended pregnancies can be averted. Unmet need for family planning will significantly decline to 11.7% by 2030. Ninety-four thousand unsafe abortions could be averted and 1233 additional maternal lives could be saved by the end of 2030 in Ethiopia.

Conclusion

Scaling up family planning has shown a significant effect to meet the SDG3 maternal mortality reduction target. A considerable proportion of unintended pregnancies and unsafe abortions can be averted by scaling up contraceptive prevalence by 2% annually until 2030. Family planning is effective and a less costly intervention to reduce maternal mortality in countries with high fertility; hence, it is highly recommended to rampup all efforts to scale up contraceptive use for improving maternal health status in Ethiopia.

Male involvement in prevention of mother to child transmission of human immunodeficiency virus and associated factors in Enebsiesarmider District, north West Ethiopia, 2018: a cross-sectional study

Background

Globally, male involvement has been identified as a priority target area to be strengthened in the prevention of mother to child transmission (PMTCT) of HIV. However, there are limited studies on husband involvement in the prevention of mother to child transmission of HIV in Ethiopia. Therefore, this study aimed to assess male involvement in the prevention of mother to child transmission of HIV and associated factors among males whose wives gave birth in the last six months before the survey in Enebsiesarmider district, Northwest Ethiopia.

Methods

A Community-based cross-sectional study was employed to assess male involvement in the prevention of mother to child transmission of human immunodeficiency virus and associated factors in Enebsiesarmider District, Northwest Ethiopia. The study was conducted from February 10–30, 2018. A total of 525 participants were involved in the study. A stratified cluster sampling method was used to recruit study participants. Data were collected using a structured interviewer-administered questionnaire. Data were entered using the epi Data software and exported to SPPS for analysis. Descriptive statistics including mean, a proportion were used to describe study variables. Multivariable logistic regression was employed to describe variables with the outcome variable.

Result

Overall male involvement in PMTCT was found to be 26.1% [95%CI, 22.1–29.5]. Respondents who have attended secondary education and above were more likely get involved in PMTCT than who have no formal education [AOR 2.45, 95%CI, 1.47–4.11], Respondents who have good knowledge on PMTCT [AOR 2.57, 95%CI, 1.58–4.18], good knowledge on ANC [AOR 2.10, 95%CI, 1.28–3.44], low cultural barriers [AOR 2.20, 95%CI, 1.34–3.63] low health system barriers [AOR 2.40, 95%CI, 1.37–4.20] were variables that significantly increase male involvement in PMTCT practices.

Conclusion

Male involvement in PMTCT was found to be low in the study area. Therefore, the district health office in collaboration with local health care providers shall design strategies for enhancing male involvement through creating a husband’s knowledge regarding the merit of prevention of mother to child transmission through the provision of adequate information for all male partners at ANC clinic is recommended.
