An Evidence Review of Gender-Integrated Interventions in Reproductive and Maternal-Child Health
Evidence-based behavior change interventions addressing gender dynamics must be identified and disseminated to improve child health outcomes. Interventions were identified from systematic searches of the published literature and a web-based search (Google and implementer's websites). Studies were eligible if an intervention addressed gender dynamics (i.e., norms, unequal access to resources), measured relevant behavioral outcomes (e.g., family planning, antenatal care, nutrition), used at least a moderate evaluation design, and were implemented in low- or middle-income countries. Of the 23 interventions identified, 22 addressed reproductive and maternal-child health behaviors (e.g., birth spacing, antenatal care, breastfeeding) that improve child health. Eight interventions were accommodating (i.e., acknowledged, but did not seek to change gender dynamics), and 15 were transformative (i.e., sought to change gender dynamics). The majority of evaluations (n=12), including interventions that engaged men and women to modify gender norms, had mixed effects. Evidence was most compelling for empowerment approaches (i.e., participatory action for maternal-child health; increase educational and economic resources, and modify norms to reduce child marriage). Two empowerment approaches had sufficient evidence to warrant scaling-up. Research is needed to assess promising approaches, particularly those that engage men and women to modify gender norms around communication and decision making between spouses
Particulate matter exposure during pregnancy is associated with birth weight, but not gestational age, 1962-1992: a cohort study
<p>Abstract</p> <p>Background</p> <p>Exposure to air pollutants is suggested to adversely affect fetal growth, but the evidence remains inconsistent in relation to specific outcomes and exposure windows.</p> <p>Methods</p> <p>Using birth records from the two major maternity hospitals in Newcastle upon Tyne in northern England between 1961 and 1992, we constructed a database of all births to mothers resident within the city. Weekly black smoke exposure levels from routine data recorded at 20 air pollution monitoring stations were obtained and individual exposures were estimated via a two-stage modeling strategy, incorporating temporally and spatially varying covariates. Regression analyses, including 88,679 births, assessed potential associations between exposure to black smoke and birth weight, gestational age and birth weight standardized for gestational age and sex.</p> <p>Results</p> <p>Significant associations were seen between black smoke and both standardized and unstandardized birth weight, but not for gestational age when adjusted for potential confounders. Not all associations were linear. For an increase in whole pregnancy black smoke exposure, from the 1<sup>st </sup>(7.4 ÎŒg/m<sup>3</sup>) to the 25<sup>th </sup>(17.2 ÎŒg/m<sup>3</sup>), 50<sup>th </sup>(33.8 ÎŒg/m<sup>3</sup>), 75<sup>th </sup>(108.3 ÎŒg/m<sup>3</sup>), and 90<sup>th </sup>(180.8 ÎŒg/m<sup>3</sup>) percentiles, the adjusted estimated decreases in birth weight were 33 g (SE 1.05), 62 g (1.63), 98 g (2.26) and 109 g (2.44) respectively. A significant interaction was observed between socio-economic deprivation and black smoke on both standardized and unstandardized birth weight with increasing effects of black smoke in reducing birth weight seen with increasing socio-economic disadvantage.</p> <p>Conclusions</p> <p>The findings of this study progress the hypothesis that the association between black smoke and birth weight may be mediated through intrauterine growth restriction. The associations between black smoke and birth weight were of the same order of magnitude as those reported for passive smoking. These findings add to the growing evidence of the harmful effects of air pollution on birth outcomes.</p
Shared heritability and functional enrichment across six solid cancers
Correction: Nature Communications 10 (2019): art. 4386 DOI: 10.1038/s41467-019-12095-8Quantifying the genetic correlation between cancers can provide important insights into the mechanisms driving cancer etiology. Using genome-wide association study summary statistics across six cancer types based on a total of 296,215 cases and 301,319 controls of European ancestry, here we estimate the pair-wise genetic correlations between breast, colorectal, head/neck, lung, ovary and prostate cancer, and between cancers and 38 other diseases. We observed statistically significant genetic correlations between lung and head/neck cancer (r(g) = 0.57, p = 4.6 x 10(-8)), breast and ovarian cancer (r(g) = 0.24, p = 7 x 10(-5)), breast and lung cancer (r(g) = 0.18, p = 1.5 x 10(-6)) and breast and colorectal cancer (r(g) = 0.15, p = 1.1 x 10(-4)). We also found that multiple cancers are genetically correlated with non-cancer traits including smoking, psychiatric diseases and metabolic characteristics. Functional enrichment analysis revealed a significant excess contribution of conserved and regulatory regions to cancer heritability. Our comprehensive analysis of cross-cancer heritability suggests that solid tumors arising across tissues share in part a common germline genetic basis.Peer reviewe
TRY plant trait database â enhanced coverage and open access
Plant traits - the morphological, anatomical, physiological, biochemical and phenological characteristics of plants - determine how plants respond to environmental factors, affect other trophic levels, and influence ecosystem properties and their benefits and detriments to people. Plant trait data thus represent the basis for a vast area of research spanning from evolutionary biology, community and functional ecology, to biodiversity conservation, ecosystem and landscape management, restoration, biogeography and earth system modelling. Since its foundation in 2007, the TRY database of plant traits has grown continuously. It now provides unprecedented data coverage under an open access data policy and is the main plant trait database used by the research community worldwide. Increasingly, the TRY database also supports new frontiers of traitâbased plant research, including the identification of data gaps and the subsequent mobilization or measurement of new data. To support this development, in this article we evaluate the extent of the trait data compiled in TRY and analyse emerging patterns of data coverage and representativeness. Best species coverage is achieved for categorical traits - almost complete coverage for âplant growth formâ. However, most traits relevant for ecology and vegetation modelling are characterized by continuous intraspecific variation and traitâenvironmental relationships. These traits have to be measured on individual plants in their respective environment. Despite unprecedented data coverage, we observe a humbling lack of completeness and representativeness of these continuous traits in many aspects. We, therefore, conclude that reducing data gaps and biases in the TRY database remains a key challenge and requires a coordinated approach to data mobilization and trait measurements. This can only be achieved in collaboration with other initiatives

Social Accountability Reporting for Research (SAR4Research): checklist to strengthen reporting on studies on social accountability in the literature
Abstract Background An increasing number of evaluations of social accountability (SA) interventions have been published in the past decade, however, reporting gaps make it difficult to summarize findings. We developed the Social Accountability Reporting for Research (SAR4Research) checklist to support researchers to improve the documentation of SA processes, context, study designs, and outcomes in the peer reviewed literature and to enhance application of findings. Methods We used a multi-step process, starting with an umbrella review of reviews on SA to identify reporting gaps. Next, we reviewed existing guidelines for reporting on behavioral interventions to determine whether one could be used in its current or adapted form. We received feedback from practitioners and researchers and tested the checklist through three worked examples using outcome papers from three SA projects. Results Our umbrella review of SA studies identified reporting gaps in all areas, including gaps in reporting on the context, intervention components, and study methods. Because no existing guidelines called for details on context and the complex processes in SA interventions, we used CONSORT-SPI as the basis for the SAR4Research checklist, and adapted it using other existing checklists to fill gaps. Feedback from practitioners, researchers and the worked examples suggested the need to eliminate redundancies, add explanations for items, and clarify reporting for quantitative and qualitative study components. Conclusions Results of SA evaluations in the peer-reviewed literature will be more useful, facilitating learning and application of findings, when study designs, interventions and their context are described fully in one or a set of papers. This checklist will help authors report better in peer-reviewed journal articles. With sufficient information, readers will better understand whether the results can inform accountability strategies in their own contexts. As a field, we will be better able to identify emerging findings and gaps in our understanding of SA
New Narratives for Africa: Using Stories to Fight HIV/AIDS
An endangered society is one whose members can no longer change the stories they tell themselves. The dangerous story line for many in sub-Saharan Africa is dominated by AIDS. Although many organizations are now arrayed to fight this scourge, the success or failure of global efforts to combat HIV/AIDS depends ultimately on people\u27s willingness and ability to behave in certain new ways - to, in effect, change their stories. This paper describes some of the unique features of a narrative intervention strategy called MARCH: Modeling and Reinforcement to Combat HIV/AIDS. In support of the U.S. government\u27s goal to help prevent and mitigate the impact of HIV/AIDS globally, the U.S. Centers for Disease Control and Prevention (CDC) is collaborating with local partners on the design, implementation, and evaluation of MARCH projects in several African countries
Dissemination and use of WHO family planning guidance and tools: a qualitative assessment
Abstract Background As countries continue to improve their family planning (FP) programmes, they may draw on WHOâs evidence-based FP guidance and tools (i.e. materials) that support the provision of quality FP services. Methods To better understand the use and perceived impact of the materials and ways to strengthen their use by countries, we conducted qualitative interviews with WHO regional advisors, and with stakeholders in Ethiopia and Senegal who use WHO materials. Results WHO uses a multi-faceted strategy to directly and indirectly disseminate materials to country-level decision-makers. The materials are used to develop national family planning guidelines, protocols and training curricula. Participants reported that they trust the WHO materials because they are evidence based, and that they adapt materials to the country context (e.g. remove content on methods not available in the country). The main barrier to the use of national materials is resource constraints. Conclusions Although the system and processes for dissemination work, improvements might contribute to increased use of the materials. For example, providers may benefit from additional guidance on how to counsel women with characteristics or medical conditions where contraceptive method eligibility criteria do not clearly rule in or rule out a method
''A Bull Cannot be Contained in a Single Kraal'': Concurrent Sexual Partnerships in Botswana
Abstract To inform efforts to curb HIV in Botswana, we describe sexual concurrency and related norms and behaviors among a sample of 807 Batswana age 15-49 years who participated in a 2003 population-based survey. Of 546 sexually active respondents, 23% reported ever having a concurrent sexual partnership with any of the last three partners from the last 12 months. Multivariate analysis found that men and youth (age <25 years), and non-religious people were more likely than their respective counterparts to report concurrency. Respondents reporting concurrency were more likely than those not, to have norms that support multiple partnerships and report low self-efficacy to be faithful to one partner. However, a majority of both groups reported believing that fidelity is important and that they would be looked down upon by family and friends if discovered to have multiple partnerships. The findings suggest that concurrency in Botswana is not uncommon, and yet may not be generally acceptable
