Abstract
Background Obstetric fistula is a childbirth injury caused by prolonged obstructed labor that results in destruction of the tissue wall between the vagina and bladder. Although obstetric fistula is directly caused by prolonged obstructed labor, many other factors indirectly increase fistula risk. Some research suggests that many women in rural Malawi have limited autonomy and decision-making power in their households. We hypothesize that women’s limited autonomy may play a role in reinforcing childbirth practices that increase the risk of obstetric fistula in this setting by hindering access to emergency care and further prolonging obstructed labor. Methods A medical student at Baylor College of Medicine partnered with a Malawian research assistant in July 2015 to conduct in-depth qualitative interviews in Chichewa with 25 women living within the McGuire Wellness Centre’s catchment area (rural Central Lilongwe District) who had received obstetric fistula repair surgery. Results This study assessed whether women’s limited autonomy in rural Malawi reinforces childbearing practices that increase risk of obstetric fistula. We considered four dimensions of autonomy: sexual and reproductive decision-making, decision-making related to healthcare utilization, freedom of movement, and discretion over earned income. We found that participants had limited autonomy in these domains. For example, many women felt pressured by their husbands, families, and communities to become pregnant within three months of marriage; women often needed to seek permission from their husbands before leaving their homes to visit the clinic; and women were frequently prevented from delivering at the hospital by older women in the community. Conclusions Many of the obstetric fistula patients in our sample had limited autonomy in several or all of the aforementioned domains, and their limited autonomy often led both directly and indirectly to an increased risk of prolonged labor and fistula. Reducing the prevalence of fistula in Malawi requires a broad understanding of the causes of fistula, so we recommend that the relationship between women’s autonomy and fistula risk undergo further investigation.

Abstract
OBJECTIVE To characterize associations between intimate partner violence (IPV) and adverse delivery outcomes among married Malawian women. METHODS In the present secondary analysis of an ongoing project investigating sexual and reproductive health decision making in rural, Lilongwe District, Malawi, married women who had experienced at least one pregnancy were interviewed between July 15, 2014, and February 25, 2015. Associations between physical IPV experienced with participants' current partners and history of adverse delivery outcomes (spontaneous abortions, stillbirths, and neonatal deaths) were examined using log-binomial regression. RESULTS The analyses included 792 women. The 166 (21.0%) participants who reported having experienced physical IPV with their current partner were significantly more likely to have a history of adverse delivery outcomes in the unadjusted (prevalence ratio 1.23; 95% confidence interval 1.08-1.41) and adjusted (adjusted prevalence ration 1.19; 95% CI 1.01-1.40) analyses. CONCLUSION Physical IPV was reported by a large proportion of participants in the present study and was significantly associated with adverse delivery outcomes. Public health interventions providing physical IPV screening and referral to support services could help improve maternal and child health in Malawi.

Abstract
The work reported here assesses the coverage achieved by two sales-based approaches to distributing a complementary food supplement (KOKO Plus™) to infants and young children in Ghana. Delivery Model 1 was conducted in the Northern Region of Ghana and used a mixture of health extension workers (delivering behavior change communications and demand creation activities at primary healthcare centers and in the community) and petty traders recruited from among beneficiaries of a local microfinance initiative (responsible for the sale of the complementary food supplement at market stalls and house to house). Delivery Model 2 was conducted in the Eastern Region of Ghana and used a market-based approach, with the product being sold through micro-retail routes (i.e., small shops and roadside stalls) in three districts supported by behavior change communications and demand creation activities led by a local social marketing company. Both delivery models were implemented sub-nationally as 1-year pilot programs, with the aim of informing the design of a scaled-up program. A series of cross-sectional coverage surveys was implemented in each program area. Results from these surveys show that Delivery Model 1 was successful in achieving and sustaining high (i.e., 86%) effective coverage (i.e., the child had been given the product at least once in the previous 7 days) during implementation. Effective coverage fell to 62% within 3 months of the behavior change communications and demand creation activities stopping. Delivery Model 2 was successful in raising awareness of the product (i.e., 90% message coverage), but effective coverage was low (i.e., 9.4%). Future programming efforts should use the health extension / microfinance / petty trader approach in rural settings and consider adapting this approach for use in urban and peri-urban settings. Ongoing behavior change communications and demand creation activities is likely to be essential to the continued success of such programming.

Abstract
OBJECTIVE To determine the effects of joint partner decision making on obstetric choices and outcomes in Malawi. METHODS Between July 15, 2014 and February 25, 2015, interviews were performed with women who reported at least one lifetime pregnancy in Lilongwe District, Malawi as part of a cross-sectional study of reproductive decision making. Logistic regression models were applied to examine associations of joint decision making with delivery location and obstetric complications. RESULTS The study population included 860 women. Women who engaged in joint decision making with partners (adjusted odds ratio [aOR] 4.9; 95% confidence interval [CI] 3.3-7.2) and women whose partners made obstetric-care decisions alone (aOR 3.2; 95% CI 2.4-4.4) were more likely to undergo delivery at a healthcare facility compared with women who made obstetric-care decisions individually. In comparison with women who made obstetric decisions individually, no difference in the likelihood of experiencing obstetric complications was observed for women who engaged in joint decision making (aOR 1.1; 95% CI 0.7-1.7) or for women whose partners made decisions individually (aOR 0.8; 95% CI 0.5-1.3). CONCLUSION In rural Malawi, partner involvement in obstetric decision making was associated with improved obstetric choices.

Abstract
A wealth of studies has indicated that greater cognitive ability is related to healthier behaviors and outcomes throughout the lifespan. In the present paper, we focus on objective numeracy (ability with numbers) and present findings from a study conducted in the Peruvian Highlands that examines the relations among formal education, numeracy, other more general cognitive skills, and a sex-related protective behavior (condom use). Our results show a potential unique protective effect of numeracy on this healthprotective behavior even after accounting for measures of fluid intelligence and potential confounding factors. These results add to a growing literature highlighting the robust protective effect on health behaviors of greater cognitive skills that are enhanced through schooling. Challenges for future research will be identifying the causal mechanisms that underlie these effects and translating this knowledge into effective interventions for improving health.

Abstract
Background In Zanzibar, a semi-autonomous region of Tanzania, induced abortion is illegal but common, and fewer than 12 % of married reproductive-aged women use modern contraception. As part of a multi-method study about contraception and consequences of unwanted pregnancies, the objective of this study was to understand the experiences of Zanzibari women who terminated pregnancies. Methods The cross-sectional study was set in Zanzibar, Tanzania. Participants were a community-based sample of women who had terminated pregnancies. We carried out semi-structured interviews with 45 women recruited via chain-referral sampling. We report the characteristics of women who have had abortions, the reasons they had abortions, and the methods used to terminate their pregnancies. Results Women in Zanzibar terminate pregnancies that are unwanted for a range of reasons, at various points in their reproductive lives, and using multiple methods. While clinical methods were most effective, nearly half of our participants successfully terminated a pregnancy using non-clinical methods and very few had complications requiring post abortion care (PAC). Conclusions Even in settings where abortion is illegal, some women experience illegal abortions without adverse health consequences, what we might call ‘safer’ unsafe abortions; these kinds of abortion experiences can be missed in studies about abortion conducted among women seeking PAC in hospitals.

Abstract
BACKGROUND Designing effective public health campaigns in areas of armed conflict requires a nuanced understanding of how violence impacts the epidemiology of the disease in question. METHODS We examine the geographical relationship between violence (represented by the location of detonated Improvised Explosive Devices) and polio incidence by generating maps of IEDs and polio incidence during 2010, and by comparing the mean number of IED detonations in polio high-risk districts with non polio high-risk districts during 2004-2009. RESULTS We demonstrate a geographic relationship between IED violence and incident polio. Districts that have high-risk for polio have highly statistically significantly greater mean numbers of IEDs than non polio high-risk districts (p-values 0.0010-0.0404). CONCLUSIONS The geographic relationship between armed conflict and polio incidence provides valuable insights as to how to plan a vaccination campaign in violent contexts, and allows us to anticipate incident polio in the regions of armed conflict. Such information permits vaccination planners to engage interested armed combatants to co-develop strategies to mitigate the effects of violence on polio.

Abstract
BACKGROUND Malawi has the highest incidence of cervical cancer in the world. Only 3% of Malawian women have ever been screened for cervical cancer. Self-collection of samples for human papillomavirus (HPV) testing could increase screening among under-screened and hard-to-reach populations. However, little is known about the acceptability of self-collection in rural African settings. AIM We aimed to characterise Malawian women's willingness to self-collect vaginal samples for HPV testing and to identify potential barriers. DESIGN We used data from the baseline wave of a community-based cohort study, collected from July 2014 to February 2015. SETTING Participants were enrolled from the catchment area of a clinic in rural Lilongwe District, Malawi. METHODS We enrolled women aged 15-39 years (n=824). Participants answered questions assessing willingness to self-collect a sample for HPV testing, concerns about testing and other hypothesised correlates of willingness to self-collect. RESULTS Two-thirds (67%) of the women reported willingness to self-collect a vaginal sample in their homes. Awareness of cervical cancer, supportive subjective norms, perceived behavioural control, and clinician recommendations were all positively associated with increased willingness to self-collect samples for HPV testing. Identified barriers to self-testing endorsed by women included: concerns that the test might hurt (22%), that they might not do the test correctly (21%), and that the test might not be accurate (17%). CONCLUSIONS This study suggests that self-collection for HPV testing could be an acceptable cervical cancer screening method in this rural population. Findings identify modifiable beliefs and barriers that can inform the development of effective screening programmes.

Abstract
A considerable number of single nucleotide polymorphisms (SNPs) are required to elucidate genotype-phenotype associations and determine the molecular basis of important traits. In this work, we carried out de novo SNP discovery accounting for both genome duplication and genetic variation from American and European salmon populations. A total of 9 736 473 nonredundant SNPs were identified across a set of 20 fish by whole-genome sequencing. After applying six bioinformatic filtering steps, 200 K SNPs were selected to develop an Affymetrix Axiom(®) myDesign Custom Array. This array was used to genotype 480 fish representing wild and farmed salmon from Europe, North America and Chile. A total of 159 099 (79.6%) SNPs were validated as high quality based on clustering properties. A total of 151 509 validated SNPs showed a unique position in the genome. When comparing these SNPs against 238 572 markers currently available in two other Atlantic salmon arrays, only 4.6% of the SNP overlapped with the panel developed in this study. This novel high-density SNP panel will be very useful for the dissection of economically and ecologically relevant traits, enhancing breeding programmes through genomic selection as well as supporting genetic studies in both wild and farmed populations of Atlantic salmon using high-resolution genomewide information.

Abstract
In Haiti, large numbers of vulnerable children and the country's particular historical context has led to a unique phenomenon known as the "restavèk" system. An estimated 300,000 Haitian children are restavèks, living as unpaid domestic servants. Child-welfare advocates describe the restavèk system as modern slavery, but researchers and advocates lack information about restavèk children's circumstances, particularly vis-à-vis other children in Haiti. In a cross-sectional analysis of a nationally representative sample, we evaluated differences in well-being (school attendance, work responsibilities, physical abuse, and hunger) between restavèk children and: (a) all non-restavèk children; and (b) the poorest quintile of non-restavèk children. As compared to all Haitian children and the poorest Haitian children, restavèk children have statistically significantly lower school attendance rates and more labor responsibilities. However, restavèk children experience statistically significantly less physical abuse and less hunger than non-restavèk Haitian children. The restavèk system remains active in Haiti because poor families lack basic resources to support their children, and restavèk children are at risk for mistreatment due to their vulnerable social status. The surprising finding that restavèk children are better off in some respects than their non-restavèk peers highlights the desperate poverty in Haiti and suggests that structural changes for poverty reduction will be required before the restavèk system will end.

Abstract
Background Although it is widely acknowledged that areas of conflict are associated with a high health burden, from a geospatial perspective it is difficult to establish these patterns at fine scales because of a lack of data. The release of the “WikiLeaks” Afghan War Diary (AWD) provides an interesting opportunity to advance analysis and theory into this interrelationship. Methods This paper will apply two different space time analyses to identify patterns of improvised explosive devices (IED) detonations for the period of 2004 to 2009 in Afghanistan. Results There is considerable spatial and temporal heterogeneity in IED explosions, with concentrations often following transportation links. The results are framed in terms of a resource for subsequent analyses to other existing health research in Afghanistan. To facilitate this, in our discussion we present a Google Earth file of overlapping rates that can be distributed to any researcher interested in combining his/her fine scale health data with a similarly granular layer of violence. Conclusion The release of the AWD presents a previously unavailable opportunity to consider how spatially detailed data about violence can be incorporated into understanding, and predicting, health related spillover effects. The AWD can enrich previous research conducted on Afghanistan, and provide a justification for future “official” data sharing at appropriately fine scales.

Abstract
Pancreas disease (PD), caused by a salmonid alphavirus (SAV), has a large negative economic and animal welfare impact on Atlantic salmon aquaculture. Evidence for genetic variation in host resistance to this disease has been reported, suggesting that selective breeding may potentially form an important component of disease control. The aim of this study was to explore the genetic architecture of resistance to PD, using survival data collected from two unrelated populations of Atlantic salmon; one challenged with SAV as fry in freshwater (POP 1) and one challenged with SAV as post-smolts in sea water (POP 2). Analyses of the binary survival data revealed a moderate-to-high heritability for host resistance to PD in both populations (fry POP 1 h2~0.5; post-smolt POP 2 h2~0.4). Subsets of both populations were genotyped for single nucleotide polymorphism markers, and six putative resistance quantitative trait loci (QTL) were identified. One of these QTL was mapped to the same location on chromosome 3 in both populations, reaching chromosome-wide significance in both the sire- and dam-based analyses in POP 1, and genome-wide significance in a combined analysis in POP 2. This independently verified QTL explains a significant proportion of host genetic variation in resistance to PD in both populations, suggesting a common underlying mechanism for genetic resistance across lifecycle stages. Markers associated with this QTL are being incorporated into selective breeding programs to improve PD resistance.

Abstract
Introduction We assessed the fertility desires, utilization of family planning (FP) methods, and incidence of pregnancies among HIV-infected women receiving care in an HIV clinic with an onsite FP services in Kinshasa, Democratic Republic of Congo. Methods Between November 2011 and May 2012, all HIV-infected women who attended a routine visit at the clinic were interviewed about their fertility desires and utilization of contraceptive methods using a structured questionnaire. Routine follow-up visit data were used to identify pregnancies recorded between the interview and June 2013. Results Overall, of the 699 HIV-infected women interviewed. 249 (35.7%) reported not wanting another child. Of the 499 (72.2%) participants who were sexually active at the time of interview, 177 (35.5%) were using an effective contraceptive method, including 70 (14.0%) women who reported using condoms consistently and 104 (20.8%) who were using injectable contraception. Overall, 88 (17.6%) sexually active participants who did not want another child were not using an effective FP method, and thus are considered to have had unmet need. During the median follow-up time of 22.2 (IQR: 20.2, 23.6) months, among all women interviewed, 96 (14.1%) became newly pregnant [pregnancy rate 9.3 (95%CI: 7.6, 11.4) per 100 women-years] including 21 (8.7%) among women who initially reported not wanting another child [unwanted pregnancy rate 5.8 (95%CI: 3.6, 9.3) per 100 women-years]. Conclusion The persistence of relatively high unmet need among women receiving HIV care in a clinic with onsite FP services suggests the existence of barriers that must be identified and addressed.

Abstract
Applying human factors principles to the design of clinical emergency guidelines is important. The UK Civil Aviation Authority uses a Checklist Assessment Tool for evaluating the content and usability of emergency drills before introduction into service on aircraft. We hypothesised that this model could be used to develop a generic medical tool. A three-stage modified Delphi process was used to adapt the above tool for use in designing medical emergency guidelines. The resulting Cognitive aids in Medicine Assessment Tool was then used to score and rank seven published difficult airway guidelines; the scores were used to assess its validity and reliability. Pearson's rank coefficient between these scores and scores from independent assessors was 0.89 (p = 0.007). Internal consistency, as assessed by Cronbach's alpha, was 0.74, 0.96 and 0.72 for the tool's three constituent domains of physical characteristics, content and layout/format, respectively. Inter-rater reliability, as assessed by Cohen's kappa, ranged from 0.33 to 0.72. The adoption of our tool has the potential to improve the usability of medical emergency guidelines.

Abstract
Recently, the hypothesis that state-level political context influences individuals' cultural values--the 'red states v. blue states' hypothesis--has been invoked to explain the hyper-polarisation of politics in the USA. To test this hypothesis, we examined individuals' knowledge about abortion in relation to the political context of their current state of residence. Drawing from an internet-survey of 586 reproductive-age individuals in the USA, we assessed two types of abortion knowledge: health-related and legality. We found that state-level conservatism does not modify the existing relationships between individual predictors and each of the two types of abortion knowledge. Hence, our findings do not support the 'red states' versus 'blue states' hypothesis. Additionally, we find that knowledge about abortion's health effects in the USA is low: 7% of our sample thought abortion before 12 weeks gestation was illegal.

Abstract
OBJECTIVE We examined the effect of partner approval of contraception on intention to use contraception among women obtaining post-abortion care in Zanzibar. STUDY DESIGN Our data source was a 2010 survey of 193 women obtaining post-abortion care at a large public hospital in Zanzibar. We used multivariable logistic regression analysis to assess associations between partner approval and intention to use contraception. RESULTS Overall, 23% of participants had used a contraceptive method in the past, and 66% reported intending to use contraception in the future. We found that partner approval of contraception and ever having used contraception in the past were each associated with intending to use contraception in the future. In the multivariable model, adjusting for past contraception use, partner approval of contraception was associated with 20 times the odds of intending to use contraception (odds ratio, 20.25; 95% confidence interval, 8.45-48.56). CONCLUSIONS We found a strong association between partner approval and intention to use contraception. Efforts to support contraceptive use must include both male and female partners. IMPLICATIONS Public health and educational efforts to increase contraceptive use must include men and be targeted to both male and female partners. Given that male partners are often not present when women obtain health care, creative efforts will be required to meet men in community settings.
