Teenage pregnancy and social disadvantage: systematic review integrating controlled trials and qualitative studies

Objectives To determine the impact on teenage pregnancy of interventions that address the social disadvantage associated with early parenthood and to assess the appropriateness of such interventions for young people in the United Kingdom

Global stakeholder perspectives of home birth: a systematic scoping review

Home birth is experienced by people very differently worldwide. These experiences likely differ by the type of stakeholder involved (women, their support persons, birth attendants, policy-makers), the experience itself (low-risk birth, transfer to hospital, previous deliveries), and by the health system within which home birth occurs (e.g., high-resource versus low- and middle-resource countries). Research evidence of stakeholders’ perspectives of home birth could usefully inform personal and policy decisions about choosing and providing home birth, but the current literature is fragmented and its breadth is not fully understood. We conducted a systematic scoping review to understand how the research literature on stakeholders’ perspectives of home birth is characterized in terms of populations, settings and identified issues, and what potential gaps exist in the research evidence. A range of electronic, web-based and key informant sources of evidence were searched. Located references were assessed, data extracted, and descriptively analyzed using robust methods. Our analysis included 460 full reports. Findings from 210 reports of studies in high-resource countries suggested that research with fathers and same-sex partners, midwives, and vulnerable populations and perspectives of freebirth and transfer to hospital could be synthesized. Gaps in primary research exist with respect to family members, policy makers, and those living in rural and remote locations. A further 250 reports of studies in low- and middle-resource countries suggested evidence for syntheses related to fathers and other family members, policy makers, and other health care providers and examination of issues related to emergency transfer to hospital, rural and remote home birth, and those who birth out of hospital, often at home, despite receiving antenatal care intended to increase healthcare-seeking behavior. Gaps in primary research suggest an examination is needed of perspectives in countries with higher maternal mortality and among first-time mothers and young mothers. Our scoping review identified a considerable body of research evidence on stakeholder perspectives of home birth. These could inform the complex factors influencing personal decisions and health system planning around home birth in both high- and low- and middle-resource countries. Future primary research is warranted on specific stakeholders worldwide and with vulnerable populations in areas of high maternal mortality

Teenage pregnancy and social disadvantage: systematic review integrating controlled trials and qualitative studies

OBJECTIVES: To determine the impact on teenage pregnancy of interventions that address the social disadvantage associated with early parenthood and to assess the appropriateness of such interventions for young people in the United Kingdom. DESIGN: Systematic review, including a statistical meta-analysis of controlled trials on interventions for early parenthood and a thematic synthesis of qualitative studies that investigated the views on early parenthood of young people living in the UK. DATA SOURCES: 12 electronic bibliographic databases, five key journals, reference lists of relevant studies, study authors, and experts in the field. Review methods Two independent reviewers assessed the methodological quality of studies and abstracted data. RESULTS: Ten controlled trials and five qualitative studies were included. Controlled trials evaluated either early childhood interventions or youth development programmes. The overall pooled effect size showed that teenage pregnancy rates were 39% lower among individuals receiving an intervention than in those receiving standard practice or no intervention (relative risk 0.61; 95% confidence interval 0.48 to 0.77). Three main themes associated with early parenthood emerged from the qualitative studies: dislike of school; poor material circumstances and unhappy childhood; and low expectations for the future. Comparison of these factors related to teenage pregnancy with the content of the programmes used in the controlled trials indicated that both early childhood interventions and youth development programmes are appropriate strategies for reducing unintended teenage pregnancies. The programmes aim to promote engagement with school through learning support, ameliorate unhappy childhood through guidance and social support, and raise aspirations through career development and work experience. However, none of these approaches directly tackles all the societal, community, and family level factors that influence young people's routes to early parenthood. CONCLUSIONS: A small but reliable evidence base supports the effectiveness and appropriateness of early childhood interventions and youth development programmes for reducing unintended teenage pregnancy. Combining the findings from both controlled trials and qualitative studies provides a strong evidence base for informing effective public policy

Antiretroviral therapy and liver disease progression in HIV and hepatitis C co-infected patients : a systematic review and meta-analysis

Background: HIV co-infection exacerbates hepatitis C disease, increasing the risk of cirrhosis and hepatitis C-related mortality. Combination antiretroviral therapy (cART) is the current standard treatment for co-infected individuals, but the impact of cART and antiretroviral (ARV) monotherapy on liver disease in this population is unclear. We aimed to assess the effect of cART and ARV monotherapy on liver disease progression and liver-related mortality in individuals co-infected with HIV and chronic hepatitis C. Methods: A systematic review with meta-analyses was conducted. MEDLINE and EMBASE bibliographic databases were searched up to September 2015. Study quality was assessed using a modified Newcastle-Ottawa scale. Results were synthesised narratively and by meta-analysis. Results: Fourteen observational studies were included. In analyses that adjusted for potential confounders, risk of liver-related mortality was significantly lower in patients receiving cART (hazard ratio/odds ratio 0.31, 95 % CI 0.14 to 0.70). Results were similar in unadjusted analyses (relative risk 0.40, 95 % CI 0.29 to 0.55). For outcomes where metaanalysis could not be performed, results were less consistent. Some studies found cART was associated with lower incidence of, or slower progression of liver disease, fibrosis and cirrhosis, while others showed no evidence of benefit. We found no evidence of liver-related harm from cART or ARV monotherapy compared with no HIV therapy. Conclusions: cART was associated with significantly lower liver-related mortality in patients co-infected with HIV and HCV. Evidence of a positive association between cART and/or ARV monotherapy and liver-disease progression was less clear, but there was no evidence to suggest that the absence of antiretroviral therapy was preferable.
