RESUMO

OBJECTIVES: Early infant diagnosis (EID) of HIV infection increases antiretroviral therapy initiation, which reduces pediatric HIV-related morbidity and mortality. This review aims to critically appraise the effects of interventions to increase uptake of early infant diagnosis. DESIGN: This is a systematic review and meta-analysis of interventions to increase the EID of HIV infection. We searched PubMed, EMBASE, CINAHL, and PsycINFO to identify eligible studies from inception of these databases to June 18, 2020. EID Uptake at 4-8 weeks of age was primary outcome assessed by the review. We conducted meta-analysis, using data from reports of included studies. The measure of the effect of dichotomous data was odds ratios (OR), with a 95% confidence interval. The grading of recommendations assessment, development, and evaluation (GRADE) approach was used to assess quality of evidence. SETTINGS: The review was not limited by time of publication or setting in which the studies conducted. PARTICIPANTS: HIV-exposed infants were participants. RESULTS: Database search and review of reference lists yielded 923 unique titles, out of which 16 studies involving 13,822 HIV exposed infants (HEI) were eligible for inclusion in the review. Included studies were published between 2014 and 2019 from Kenya, Nigeria, Uganda, South Africa, Zambia, and India. Of the 16 included studies, nine (experimental) and seven (observational) studies included had low to moderate risk of bias. The studies evaluated eHealth services (n = 6), service improvement (n = 4), service integration (n = 2), behavioral interventions (n = 3), and male partner involvement (n = 1). Overall, there was no evidence that any of the evaluated interventions, including eHealth, health systems improvements, integration of EID, conditional cash transfer, mother-to-mother support, or partner (male) involvement, was effective in increasing uptake of EID at 4-8 weeks of age. There was also no evidence that any intervention was effective in increasing HIV-infected infants' identification at 4-8 weeks of age. CONCLUSIONS: There is limited evidence to support the hypothesis that interventions implemented to increase uptake of EID were effective at 4-8 weeks of life. Further research is required to identify effective interventions that increase early infant diagnosis of HIV at 4-8 weeks of age. PROSPERO NUMBER: (CRD42020191738).

RESUMO

PURPOSE: In the United States, Hispanics are more likely to be diagnosed with cervical cancer compared to Non-Hispanic Whites. Annually, 250,000 to 1 million women are diagnosed with a precursor to CC. The aim of this study was to assess whether Hispanics have a higher prevalence of cervical dysplasia compared to Non-Hispanics Whites among a population of low-income women. PATIENTS AND METHODS: We analyzed the results of 10,911 cervical cytology tests administered between 2003 and 2016 that were funded through the Center for Disease Control and Prevention's (CDC) program for low-income, uninsured women entitled the National Breast and Cervical Cancer Early Detection Program (NBCCEDP). In the state of Arizona, the program is called the Well Women HealthCheck Program (WWHP). Logistic regression was used to identify increased risk of dysplasia, including low-grade squamous intraepithelial lesions (LSIL) and high-grade squamous intraepithelial lesions (HSIL/ICC), and multinomial logistic regression was used to assess increased likelihood for LSIL and HSIL/ICC as separate categories. RESULTS: In the crude analysis, Hispanic ethnicity was modestly associated with higher prevalence of LSIL (odds ratio (OR)=1.39, 95% CI=1.01-1.91), but this association was not statistically significant after adjusting for confounders. However, in the final models, lower income was independently associated with LSIL (adjusted odds ratio [aOR]=1.55, 95% CI=1.30-1.44), while smoking (aOR=2.88, 95% CI=1.21-6.84) and no history of Pap test within five years (aOR=3.54, 95% CI=1.61-6.99) were independently associated with HSIL. CONCLUSION: After adjusting for confounding in a sample of low-income women with comparable Pap screening rates, ethnicity was not associated with greater prevalence of abnormal pap smears. However, other variables were independently associated with LSIL and HSIL. The higher proportion of LSIL cases among lower income individuals compared to those with higher incomes, and the higher proportion of HSIL cases observed among those screened least regularly stresses the importance of programs like WWHP: programs that target low-income, uninsured women. These programs help save lives.

RESUMO

BACKGROUND: D-limonene and its derivatives have demonstrated potential chemopreventive and anticancer activity in preclinical and clinical studies. The aim of this scoping review was to assess and critically appraise current literature on the effect of these bioactive citrus peel compounds on breast cancer in human trials and to identify knowledge gaps for exploration in future studies. METHODS: This study followed a scoping review framework. Peer-reviewed journal articles were included if they reported the effect of d-limonene or its derivatives on breast cancer in human subjects. Articles were retrieved from academic databases - PubMed, EMBASE, CINAHL, Web of Science, and Cochrane reviews - and iteratively through review of bibliographies of relevant manuscripts. Titles and abstracts were appraised against the aforementioned inclusion criteria in a first round of screening. Through consensus meetings and full article review by authors, a final set of studies were selected. Results were reported according to the PRISMA extension for scoping reviews. RESULTS: Our search strategy yielded 367 records. Following screening and adjudication, five articles reporting on phase 1(n = 2), phase 2 (n = 2) and both trial phases (n = 1) were included as the final dataset for this review. Trials evaluating the effect of d-limonene (n = 2) showed it was well tolerated in subjects. One study (n = 43 participants) showed d-limonene concentrated in breast tissue (mean 41.3 µg/g tissue) and reduction in tumor cyclin D1 expression, which is associated with tumor proliferation arrest. This study did not show meaningful change in serum biomarkers associated with breast cancer, except for a statistically significant increase in insulin-like growth factor-1 (IGF-I) levels. While elevation of IGF-I is associated with increased cancer risk, the clinical implication of this study remains uncertain given its short duration. Trials with perillyl alcohol (n = 3) showed low tolerance and no effect on breast cancer. CONCLUSION: This review demonstrated a dearth of clinical studies exploring the effect of d-limonene and its derivatives on breast cancer. Limited literature suggests d-limonene is safe and tolerable in human subjects compared to its derivative, perillyl alcohol. Our review demonstrates the need for additional well-powered placebo-controlled trials that assess d-limonene's efficacy on breast cancer compared to other therapies.

RESUMO

Background: Type 2 diabetes (T2D) poses a disproportionate burden on Benin, West Africa. However, no diabetes intervention has yet been developed for Benin's contexts. This study aimed to explore specific cultural beliefs, attitudes, behaviors, and environmental factors to help adapt a diabetes self-management program to patients with T2D from Cotonou, in southern Benin. Methods: Qualitative data were collected through focus group discussions (FDGs) involving 32 patients with T2D, 16 academic partners, and 12 community partners. The FDGs were audio-recorded, transcribed verbatim from French to English, and then analyzed thematically with MAXQDA 2020. Results: Healthy food was challenging to obtain due to costs, seasonality, and distance from markets. Other issues discussed were fruits and vegetables as commodities for the poor, perceptions and stigmas surrounding the disease, and the financial burden of medical equipment and treatment. Information about local food selections and recipes as well as social support, particularly for physical activity, were identified, among other needs. When adapting the curriculum, gender dynamics and spirituality were suggested. Conclusions: The study demonstrates the need for culturally sensitive interventions and a motivation-based approach to health (spiritual and emotional support). It also lays the groundwork for addressing T2D contextually in Benin and similar sub-Saharan African countries.

RESUMO

BACKGROUND: Cervical cancer disproportionately affects women in sub-Saharan Africa, compared with other world regions. In Ethiopia, a National Cancer Control Plan published in 2015, outlines an ambitious strategy to reduce the incidence and mortality of cervical cancer. This strategy includes widespread screening using visual inspection with acetic acid (VIA). As the national screening program has rolled out, there has been limited inquiry of provider experiences. This study aims to describe cancer control experts' perspectives regarding the cancer control strategy and implementation of VIA. METHODS: Semi-structured interviews with 18 participants elicited provider perspectives on cervical cancer prevention and screening. Open-ended interview questions queried barriers and facilitators to implementation of a new national screening program. Responses were analyzed using thematic analysis and mapped to the Integrated Behavioral Model. Participants were health providers and administrators with positionality as cancer control experts including screening program professionals, oncologists, and cancer focal persons at town, zone, and federal health offices at eleven government facilities in the Arsi, Bale, and Shoa zones of the Oromia region, and in the capital Addis Ababa. RESULTS: The cancer control plan and screening method, VIA, were described by participants as contextually appropriate and responsive to the unique service delivery challenges in Ethiopia. Screening implementation barriers included low community- and provider-awareness of cervical cancer and screening, lack of space and infrastructure to establish the screening center, lack of materials including cryotherapy machines for the "screen-and-treat" approach, and human resource issues such as high-turnover of staff and administration. Participant-generated solutions included additional training for providers, demand creation to increase patient flow through mass media campaigns, decentralization of screening from large regional hospitals to local health centers, improved monitoring and evaluation, and incentivization of screening services to motivate health providers. CONCLUSIONS: As the Ethiopian government refines its Cancer Control Plan and scales up screening service implementation throughout the country, the findings from this study can inform the policies and practices of cervical cancer screening. Provider perspectives of barriers and facilitators to effective cancer control and screening implementation reveal areas for continued improvement such as provider training and coordination and collaboration in the health system.

RESUMO

BACKGROUND: Medical cannabis (MC) is currently being used as an adjunct to opiates given its analgesic effects and potential to reduce opiate addiction. This review assessed if MC used in combination with opioids to treat non-cancer chronic pain would reduce opioid dosage. METHODS: Four databases-Ovid (Medline), Psyc-INFO, PubMed, Web of Science, and grey literature-were searched to identify original research that assessed the effects of MC on non-cancer chronic pain in humans. Study eligibility included randomized controlled trials, controlled before-and-after studies, cohort studies, cross-sectional studies, and case reports. All databases were searched for articles published from inception to October 31, 2019. Cochrane's ROBINS-I tool and the AXIS tool were used for risk of bias assessment. PRISMA guidelines were followed in reporting the systematic review. RESULTS: Nine studies involving 7222 participants were included. There was a 64-75% reduction in opioid dosage when used in combination with MC. Use of MC for opioid substitution was reported by 32-59.3% of patients with non-cancer chronic pain. One study reported a slight decrease in mean hospital admissions in the past calendar year (P = .53) and decreased mean emergency department visits in the past calendar year (P = .39) for patients who received MC as an adjunct to opioids in the treatment of non-cancer chronic pain compared to those who did not receive MC. All included studies had high risk of bias, which was mainly due to their methods. CONCLUSIONS: While this review indicated the likelihood of reducing opioid dosage when used in combination with MC, we cannot make a causal inference. Although medical cannabis' recognized analgesic properties make it a viable option to achieve opioid dosage reduction, the evidence from this review cannot be relied upon to promote MC as an adjunct to opioids in treating non-cancer chronic pain. More so, the optimal MC dosage to achieve opioid dosage reduction remains unknown. Therefore, more research is needed to elucidate whether MC used in combination with opioids in the treatment of non-cancer chronic pain is associated with health consequences that are yet unknown. SYSTEMATIC REVIEW REGISTRATION: This systematic review was not registered.

RESUMO

Minority youth represent a unique population for public health interventions given the social, economic, and cultural barriers they often face in accessing health services. Interventions to increase uptake of Human Papillomavirus (HPV) vaccination in minority youth have the potential to reduce disparities in HPV infection and HPV-related cancers. This systematic review assesses the effectiveness of interventions to increase HPV vaccine uptake, measured as vaccine series initiation and series completion, among adolescents and young adults, aged 9-26 years old, identifying as a racial and ethnic minority or sexual and gender minority (SGM) group in high-income countries. Of the 3013 citations produced by a systematic search of three electronic databases (PubMed, Embase, and Web of Science) in November 2018, nine studies involving 9749 participants were selected for inclusion. All studies were conducted in the United States and were published from 2015 to 2018. Interventions utilized education, vaccine appointment reminders, and negotiated interviewing to increase vaccination. Participants were Black or African American (44.4%), Asian (33.3%), Hispanic or Latinx (22.2%), American Indian or Alaska Native (11.1%), and SGM (22.2%). Studies enrolled parent-child dyads (33.3%), parents alone (11.1%), and youth alone (55.6%). Vaccine series initiation ranged from 11.1% to 84% and series completion ranged from 5.6% to 74.2% post-intervention. Educational and appointment reminder interventions may improve HPV vaccine series initiation and completion in minority youth in the U.S. Given the lack of high quality, adequately powered studies, further research is warranted to identify effective strategies for improving HPV vaccine uptake for minority populations.

RESUMO

BACKGROUND: Sub-Saharan Africa (SSA) experiences disproportionate burden of cervical cancer incidence and mortality due in part to low uptake of cervical screening, a strategy for prevention and down-staging of cervical cancer. This scoping review identifies studies of interventions to increase uptake of cervical screening among women in the region and uses the Integrated Behavioral Model (IBM) to describe how interventions might work. METHODS: A systematic search of literature was conducted in PubMed, Web of Science, Embase, and CINAHL databases through May 2019. Screening and data charting were performed by two independent reviewers. Intervention studies measuring changes to uptake in screening among women in SSA were included, with no restriction to intervention type, study setting or date, or participant characteristics. Intervention type and implementation strategies were described using behavioral constructs from the IBM. RESULTS: Of the 3704 citations the search produced, 19 studies were selected for inclusion. Most studies were published between 2014 and 2019 (78.9%) and were set in Nigeria (47.4%) and South Africa (26.3%). Studies most often assessed screening with Pap smears (31.6%) and measured uptake as ever screened (42.1%) or screened during the study period (36.8%). Education-based interventions were most common (57.9%) and the IBM construct of knowledge/skills to perform screening was targeted most frequently (68.4%). Willingness to screen was high, before and after intervention. Screening coverage ranged from 1.7 to 99.2% post-intervention, with six studies (31.6%) reporting a significant improvement in screening that achieved ≥60% coverage. CONCLUSIONS: Educational interventions were largely ineffective, except those that utilized peer or community health educators and mHealth implementation strategies. Two economic incentivization interventions were moderately effective, by acting on participants' instrumental attitudes, but resulted in screening coverage less than 20%. Innovative service delivery, including community-based self-sampling, acted on environmental constraints, striving to make services more available, accessible, and appropriate to women, and were the most effective. This review demonstrates that intent to perform screening may not be the major determinant of screening behavior, suggesting other theoretical frameworks may be needed to more fully understand uptake of cervical screening in sub-Saharan Africa, particularly for health systems change interventions.

RESUMO

BACKGROUND: Obesity-related cancers disproportionately affect the Black community. We assessed the relationship between diet quality, physical activity, and their combined effect on obesity-related cancer risk and mortality in Black women enrolled in the Women's Health Initiative (WHI). METHODS: Data from postmenopausal (50-79 years of age) Black women enrolled in WHI clinical trials or observational studies were analyzed. Exposure variables included baseline physical activity [metabolic equivalent of tasks (MET)-hours/week of moderate-to-vigorous physical activity (MVPA)] and diet quality [Healthy Eating Index (HEI)-2015]. Outcomes included adjudicated obesity-related cancer incidence and mortality. Cox proportional hazard models were used to evaluate the association between MVPA and HEI-2015 and obesity-related cancer risk and mortality. RESULTS: The analytical sample included 9,886 Black women, with a baseline mean body mass index (BMI) of 31.1 kg/m2 (SD = 6.8); mean HEI-2015 score of 63.2 (SD = 11.0, possible range 0 to 100); and mean MVPA of 5.0 (SD = 9.4) MET-hours/week. Over an average of 13 years of follow-up, 950 (9.6%) obesity-related cancer cases were observed, with 313 (32.9%) resulting in death. Physical activity [HR, 1.05; 95% confidence interval (CI), 0.86-1.30], diet quality (HR, 0.99; 95% CI, 0.92-1.08), and their combination (HR, 1.05; 95% CI, 0.85-1.29) were not associated with risk for any or site-specific obesity-related cancers. Similarly, these health behaviors had no association with mortality. CONCLUSIONS: Diet quality, physical activity and their combined effect, as measured, were not associated with obesity-related cancer risk and mortality in Black women enrolled in WHI. IMPACT: Other social, behavioral, and biological factors may contribute to racial disparities observed in obesity-related cancer rates.

RESUMO

Alzheimer's disease (AD) is a growing public health concern with large disparities in incidence and prevalence between African Americans (AAs) and non-Hispanic whites (NHWs). The aim of this review was to examine the evidence of association between six modifiable risk factors (education, smoking, physical inactivity, obesity, social isolation, and psychosocial stress) and Alzheimer's disease risk in AAs and NHWs. We identified 3,437 studies; 45 met inclusion criteria and were included in this review. Of the examined risks, education provided the strongest evidence of association with cognitive outcomes in AAs and NHWs. This factor may operate directly on Alzheimer's disease risk through the neurocognitive benefits of cognitive stimulation or indirectly through social status.

RESUMO

A theoretical framework serves as a roadmap for the implementation and application of a complex, health promotion intervention; is used to test hypotheses; and guides analysis and evaluation of the intervention. The purpose of this article is to demonstrate how a theoretical framework was developed and used to guide the implementation of Healthy Beginning Initiative (HBI) to promote uptake of HIV services in a low-income country. We used the guide for developing a theoretical framework published in Health Promotion Practice. Developing the theoretical framework included seven steps: (1) identifying the essential elements of the intervention; (2) identifying the variables and the context; (3) listing the postulated mechanisms, mediating variables, and postulated outcomes; (4) identifying existing theoretical models supporting the theoretical framework underdevelopment; (5) scripting the theoretical framework into either a figure or sets of statements; (6) conducting content and face validation of the theoretical framework; and (7) revising the theoretical framework. The theoretical framework was developed and used to evaluate HBI's impact on HIV testing, linkage to care and retention in care for pregnant women, their male partners, and newborns. The theoretical framework will also be adapted for other screenings and other settings while remaining true to the essential elements of HBI.

RESUMO

Male partner involvement has the potential to increase uptake of interventions to prevent mother-to-child transmission of HIV (PMTCT). Finding cultural appropriate strategies to promote male partner involvement in PMTCT programs remains an abiding public health challenge. We assessed whether a congregation-based intervention, the Healthy Beginning Initiative (HBI), would lead to increased uptake of HIV testing among male partners of pregnant women during pregnancy. A cluster-randomized controlled trial of forty churches in Southeastern Nigeria randomly assigned to either the HBI (intervention group; IG) or standard of care referral to a health facility (control group; CG) was conducted. Participants in the IG received education and were offered onsite HIV testing. Overall, 2498 male partners enrolled and participated, a participation rate of 88.9%. Results showed that male partners in the IG were 12 times more likely to have had an HIV test compared to male partners of pregnant women in the CG (CG = 37.71% vs. IG = 84.00%; adjusted odds ratio = 11.9; p < .01). Culturally appropriate and community-based interventions can be effective in increasing HIV testing and counseling among male partners of pregnant women.

RESUMO

INTRODUCTION: In spite of a high prevalence of HIV infection among adolescents and young adults in sub-Saharan Africa, uptake of HIV testing and counseling among youth in the region remains sub-optimal. The objective of this study was to assess factors that influence uptake of HIV testing and counseling among youth aged 15-24 years in sub-Saharan Africa. METHODS: This study used the Demographic and Health Survey (DHS) data from countries that represent four geographic regions of sub-Saharan Africa: Congo (Brazzaville), representing central Africa (DHS 2011-2012); Mozambique, representing southern Africa (DHS 2011); Nigeria, representing western Africa (DHS 2013); and Uganda, representing eastern Africa (DHS 2011). Analyses were restricted to 23,367 male and female respondents aged 15-24 years with complete data on the variables of interest. Chi-square tests and logistic regression models were used to assess predictors of HIV testing. Statistical significance was set at p< 0.01. RESULTS: The analysis revealed that a majority of the respondents were female (78.1%) and aged 20-24-years (60.7%). Only a limited proportion of respondents (36.5%) had ever tested for HIV and even fewer (25.7%) demonstrated comprehensive knowledge of HIV/AIDS. There was a significant association between HIV testing and respondents' gender, age, age at sexual debut, and comprehensive knowledge of HIV in the pooled sample. Older youth (adjusted OR (aOR) = 2.19; 99% CI = 1.99-2.40) and those with comprehensive knowledge of HIV (aOR = 1.98; 1.76-2.22) had significantly higher odds of ever being tested for HIV than younger respondents and those with limited HIV/AIDS knowledge respectively. Furthermore, men had lower odds of HIV testing than women (aOR = 0.32; 0.28-0.37). CONCLUSIONS: Reaching youth in sub-Saharan Africa for HIV testing continues to be a challenge. Public health programs that seek to increase HIV counseling and testing among youth should pay particular attention to efforts that target high-risk subpopulations of youth. The results further suggest that these initiatives would be strengthened by including strategies to increase HIV comprehensive knowledge.

RESUMO

Despite improved availability of simple, relatively inexpensive, and highly effective antiretroviral treatment for HIV/AIDS, the disease remains a major public health challenge for women in sub-Saharan Africa (SSA). Given the numerous barriers in access to care for women in this region, every health issue that brings them into contact with the health system should be optimized as an opportunity to integrate HIV/AIDS prevention. Because most non-condom forms of modern contraception require a clinical appointment for use, contraception appointments could provide a confidential opportunity for access to HIV counseling, testing, and referral to care. This study sought to investigate the relationship between contraceptive methods and HIV testing among women in SSA. Data from the Demographic and Health Survey from four African countries-Congo, Mozambique, Nigeria, and Uganda-was used to examine whether modern (e.g., pills, condom) or traditional (e.g., periodic abstinence, withdrawal) forms of contraception were associated with uptake of HIV testing. Data for the current analyses were restricted to 35,748 women with complete information on the variables of interest. Chi-square tests and logistic regression models were used to assess the relationship between uptake of HIV testing and respondents' baseline characteristics and contraceptive methods. In the total sample and in Mozambique, women who used modern forms of contraception were more likely to be tested for HIV compared to those who did not use contraception. This positive association was not demonstrated in Congo, Nigeria, or Uganda. That many women who access modern contraception are not tested for HIV in high HIV burden areas highlights a missed opportunity to deliver an important intervention to promote maternal and child health. Given the increasing popularity of hormonal contraception methods in low-income countries, there is an urgent need to integrate HIV counseling, testing, and treatment into family planning programs. Women on hormonal contraceptives should be encouraged to continue to use condoms for HIV-prevention.

RESUMO

BACKGROUND: Although TB health promotion directed at policy makers and healthcare workers (HCWs) is considered important to tuberculosis (TB) control, no indicators currently assess the impact of such promotional activities. This article is the second in a series of papers that seek to establish a framework of behavioral indicators for outcome evaluation of TB health promotion, using the Delphi method. In the first article, we sought to establish a framework of behavioral indicators for outcome evaluation of TB health promotion among TB suspects and patients. The objective of this second article is to present an indicator framework that can be used to assess behavioral outcomes of TB health promotion directed at policy makers and HCWs. METHODS: A two-round, modified Delphi method was used to establish the indicators. Sixteen experts who were knowledgeable and experienced in the field of TB control were consulted in Delphi surveys. A questionnaire was developed following 4 steps, and involved ranking indicators on a five-point Likert scale. The consensus level was 70 %. Median, mode, and Coefficient of variation (CV) were used to describe expert responses. An authority coefficient (Cr) was used to assess the degree of each expert's authority. RESULTS: Consensus was achieved following the two survey rounds and several iterations among the experts. For TB health-promotion activities directed at policymakers, the experts reached consensus on 2 domains ("Resource inputs" and "Policymaking and monitoring behaviors"), 4 subdomains ("Human resources" among others), and 13 indicators ("Human resources per 100,000 person" among others). For TB health-promotion activities directed at HCWs, the experts reached consensus on 5 domains ("Self-protective behaviors" among others), 6 sub-domains ("Preventing infection" among others), and 15 indicators ("Average hours of daily workplace disinfection by ultraviolet radiation" among others). CONCLUSIONS: This study identified a conceptual framework of core behavioral indicators to evaluate TB health-promotion activities directed at policymakers and HCWs involved in TB control. Validation in other parts of the world could lead to global consensus on behavioral indicators to evaluate TB health promotion targeted at policymakers and HCWs.

RESUMO

BACKGROUND: Few effective community-based interventions exist to increase HIV testing and uptake of antiretroviral therapy (ART) in pregnant women in hard-to-reach resource-limited settings. We assessed whether delivery of an intervention through churches, the Healthy Beginning Initiative, would increase uptake of HIV testing in pregnant women compared with standard health facility referral. METHODS: In this cluster randomised trial, we enrolled self-identified pregnant women aged 18 years and older who attended churches in southeast Nigeria. We randomised churches (clusters) to intervention or control groups, stratified by mean annual number of infant baptisms (<80 vs ≥80). The Healthy Beginning Initiative intervention included health education and on-site laboratory testing implemented during baby showers in intervention group churches, whereas participants in control group churches were referred to health facilities as standard. Participants and investigators were aware of church allocation. The primary outcome was confirmed HIV testing. This trial is registered with ClinicalTrials.gov, identifier number NCT 01795261. FINDINGS: Between Jan 20, 2013, and Aug 31, 2014, we enrolled 3002 participants at 40 churches (20 per group). 1309 (79%) of 1647 women attended antenatal care in the intervention group compared with 1080 (80%) of 1355 in the control group. 1514 women (92%) in the intervention group had an HIV test compared with 740 (55%) controls (adjusted odds ratio 11·2, 95% CI 8·77-14·25; p<0·0001). INTERPRETATION: Culturally adapted, community-based programmes such as the Healthy Beginning Initiative can be effective in increasing HIV screening in pregnant women in resource-limited settings. FUNDING: US National Institutes of Health and US President's Emergency Plan for AIDS Relief.

RESUMO

BACKGROUND: Despite the growing body of evidence on use of modern contraceptives among women in sub-Saharan African countries, little is known about the broader context in which female decision-making concerning contraceptive use occurs, particularly the role of their male partners' awareness and support of modern contraceptives. METHODS: We conducted a cross-sectional survey of 2468 pregnant women and their male partners enrolled in the Healthy Beginning Initiative (HBI), an intervention to increase HIV testing among pregnant women in Enugu, southeast Nigeria. The aims of this study were to determine: 1) male partners' awareness of, and support for, female contraceptive methods, and 2) influence of male partners' contraceptive awareness and support on pregnant women's expressed desire to use contraception. We used logistic regression models to examine the association between male partners' awareness and support of modern contraceptives on their spouses' desire to use contraceptives. RESULTS: Men's awareness of, and support for, use of modern contraceptives were significantly associated with their female partners' desire to use contraception. A majority of the men who were aware of modern contraceptives (66.5 %) and those who supported their spouses' use of contraception (72.5 %) had partners who expressed a desire to use contraception. Men who were aware of female contraception were 3 times more likely to have spouses who desired to use contraception (AOR = 3.17, 95 % C.I: 2.70-3.75). In addition, men who showed support for their spouses' use of contraception were over 5 times more likely to have spouses who indicated a desire to use contraception (AOR = 5.76, 95 % C.I: 4.82-6.88). Living in a household of 5 or more people (AOR = 1.45, 95 % C.I: 1.23-1.72) and residing in an urban area (AOR = 0.81, 95 % C.I: 0.67-0.97) were also significantly associated with women's expressed desire to use modern contraception. CONCLUSION: Men's awareness of, and support for, use of modern contraceptives were markedly associated with their spouses' desire to use contraception. This underscores the need for men's involvement in programs that seek to address women's uptake of contraception in low and middle income countries.

RESUMO

INTRODUCTION: The effects of exposure to marijuana in utero on fetal development are not clear. Given that the recent legislation on cannabis in the US is likely to result in increased use, there is a need to assess the effects of prenatal cannabis exposure on fetal development and pregnancy outcomes. The objective of this review is to assess the effects of prenatal exposure to cannabis on pregnancy outcomes (including maternal and child outcomes). METHODS AND ANALYSES: Major databases will be searched from inception to the latest issue, with the aim of identifying studies that reported the effects of prenatal exposure to cannabis on fetal development and pregnancy outcomes. Two investigators will independently review all titles and abstracts to identify potential articles. Discrepancies will be resolved by repeated review, discussion and consensus. Study quality assessment will be undertaken, using standard protocols. To qualify for inclusion, studies must report at least one maternal or neonatal outcome post partum. Cross-sectional, case-control, cohort and randomised controlled trials published in English will be included. In order to rule out the effects of other drugs that may affect fetal development and pregnancy outcomes, studies will only be included if they report outcomes of prenatal exposure to cannabis while excluding other illicit substances. Data from eligible studies will be extracted, and data analysis will include a systematic review and critical appraisal of evidence, and meta-analysis if data permit. Meta-analysis will be conducted if three or more studies report comparable statistics on the same outcome. ETHICS AND DISSEMINATION: The review which will result from this protocol has not already been conducted. Preparation of the review will follow the procedures stated in this protocol, and will adhere to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Ethical approval of data will not be required since the review will use data that are already available in the public domain through published articles and other reports.

RESUMO

PURPOSE: Although the prevalence of mental health disorders in Nigeria is comparable to most developed countries, access to mental health care in Nigeria is limited. Improving access to care requires innovative approaches that deliver mental health interventions at the community level. The aim of this study was to determine the feasibility and acceptability of integrating mental health screening into an existing community-based program for prevention of mother-to-child transmission of HIV targeted at pregnant women and their male partners. METHODS: Pregnant women and their male partners from 117 churches enrolled in the healthy beginning initiative (HBI) in southeast Nigeria participated in the mental health screening project. Two members from each church were trained as church-based health advisors to administer the 12-item general health questionnaire. RESULTS: Ninety-three percent of the pregnant women and their male partners agreed to participate and fully completed the questionnaire. Overall, 21.7 % of the respondents scored above the threshold of 11 indicating significant psychological distress, with women having significantly higher scores than men. CONCLUSION: Mental health screening is feasible and well accepted among a cohort of pregnant women and their male partners. Church members can be trained as health advisors to administer mental health screening. Mental health interventions can be developed on the framework of the HBI.

RESUMO

PURPOSE: In the Alabama Black Belt, poverty is high, and the educational level is low. Studies have found increased tobacco use among individuals exposed to high levels of stress. Few studies have been conducted in this region to measure smoking status, its sociodemographic determinants, and how smoking status relates to stressful environmental conditions. METHODS: A cross-sectional questionnaire survey of 1,387 individuals. FINDINGS: Approximately 25% of the respondents currently smoked cigarettes. Females were less likely to smoke compared to males (OR, 0.29; 95% CI, 0.23-0.38). Blacks were less likely to smoke cigarettes compared to whites (OR, 0.64; 95% CI, 0.43-0.95). Compared to individuals who were employed, participants who were unemployed or retired had increased odds of smoking (OR, 1.68; 95% CI, 1.15-2.20). The odds of being a current smoker were increased in the presence of moderate level stress (OR, 2.06; 95% CI, 1.38-3.07) or when there was a high level of stress (OR, 2.21; 95% CI, 1.47-3.31). Smoking was associated with increased odds of having a moderate level (OR, 2.06; 95% CI, 1.38-3.08) and a high level of stress (OR, 2.21; 95% CI, 1.47-3.32). Females who reported moderate to high levels of stress had increased odds of being smokers compared to males. Interaction between gender and stress showed deviation from additivity. CONCLUSION: Our findings suggest a high rate of cigarette use in the area. Increased stress levels appear to predispose females more than males to cigarette smoking. The implications of this association may guide interventions targeted at reducing smoking and its complications.
