Analyzing program data and promotional approaches to inform best practices from a mobile phone-based reproductive health message program in Afghanistan.

Objective: Digital health technologies have contributed to the adoption of beneficial reproductive, maternal, newborn, and child health (RMNCH) behaviors through social and behavior change programming, including in hard-to-reach settings. On-demand digital health interventions rely on promotions to build awareness and increase use among target audiences. There is little research on preferred content and use of promotional approaches for RMNCH digital health activities. Methods: We conducted a retrospective descriptive analysis of Mobile for Reproductive Health (m4RH) data in Afghanistan to assess the use and changes in call volume via the 2-3-4 platform by promotional approaches over 23 months between October 2017 and August 2019. Results: There were 103,859 completed messages (CM) heard. Most callers reporting demographics were under 18 years, with roughly even distribution by gender. The number of CMs listened to across all menus increased with time. The basic m4RH family planning menu was most popular, with callers most frequently selecting information on intrauterine contraceptive devices. Nine types of promotional approaches were implemented. Compared against call volume, SMS blast promotion was the most productive promotional approach, radio broadcasts had modest increases, and social media and interpersonal communication demonstrated no clear change. Conclusions: m4RH use increased over time, particularly among younger people. The number of promotional approaches used does not appear as important as the type of approach used to generate program awareness. Mass media communications, including SMS blast promotions and radio broadcasts, may be the most effective strategies. Deeper program data analysis can guide tailoring of message content and promotional approaches to reach target audiences with the RMNCH content they most value.

Feasibility and acceptability of a video library tool to support community health worker counseling in rural Afghan districts: a cross-sectional assessment.

BACKGROUND: Rural Afghan populations have low skilled birth attendance rates and high maternal and infant mortality. Insecurity and armed conflict, geographic barriers, and cultural norms often hinder women's access to facility-based reproductive, maternal, newborn, and child health (RMNCH) services. Community health workers (CHWs) are critical agents for behavioral change in this and similarly fragile settings, where RMNCH information exposure is limited by low literacy and mass media access. We assessed the feasibility and acceptability of a computer tablet-based health video library (HVL) to enhance CHW counseling on RMNCH topics in three rural Afghan districts. METHODS: The HVL was introduced by trained CHWs in 10 pilot communities within one rural district in each of Balkh, Herat, and Kandahar provinces. We used a mixed-methods study design to assess exposure to and perception of the HVL 6 months post-introduction. We surveyed married women (n = 473) and men (n = 468) with at least one child under 5 years and conducted in-depth interviews with CHWs and community leaders (shuras and Family Health Action groups) within pilot communities (n = 80). Program improvement needs were summarized using quantitative and qualitative data. RESULTS: Higher proportions of women in Balkh (60.3%) and Herat (67.3%) reported viewing at least one HVL video compared to women in Kandahar (15%), while male HVL exposure was low (8-17%) across all districts. Most HVL-exposed clients (85-93% of women and 74-92% of men) reported post-video counseling by CHWs. Nearly all (94-96% of women and 85-92% of men) were very interested in watching videos on other health topics in the future. Participants recommended increasing the number of videos and range of topics, using tablets with larger screens, and translating videos into additional local languages to improve the HVL program. CONCLUSION: The HVL was a highly acceptable tool for relaying health information, but coverage of female audiences in Kandahar and male audiences broadly was low. The HVL should better engage men and other key influencers to engineer local solutions that directly facilitate male HVL exposure, indirectly improve women's HVL access, and support collaborative spousal health decision-making. A larger efficacy trial is warranted to measure the HVL's effect on knowledge and health-related behavioral outcomes.

Feasibility and Acceptability of an Adapted Mobile Phone Message Program and Changes in Maternal and Newborn Health Knowledge in Four Provinces of Afghanistan: Single-Group Pre-Post Assessment Study.

BACKGROUND: Mobile phone apps for health promotion have expanded in many low- and middle-income countries. Afghanistan, with high maternal and newborn morbidity and mortality rates, a fragile health infrastructure, and high levels of mobile phone ownership, is an ideal setting to examine the utility of such programs. We adapted messages of the Mobile Alliance for Maternal Action (MAMA) program, which was designed to promote healthy behaviors during pregnancy and a newborn's first year of life, to the Afghan context. We then piloted and assessed the program in the provinces of Kabul, Herat, Kandahar, and Balkh. OBJECTIVE: The aim of this study was to assess the feasibility and acceptability of the MAMA pilot program, and to examine changes in reported maternal, newborn, and child health (MNCH) knowledge and attitudes among participants from baseline to follow up. METHODS: We conducted a single-group study with data collected within 10 weeks of enrollment, and data collection was repeated approximately 6 months later. Data were collected through face-to-face interviews using structured questionnaires. Eligible participants included pregnant women who had registered to receive fully automated mobile health messages and their husbands. Assessment questionnaires queried sociodemographic details; knowledge, attitudes, and health care-seeking practices; and intervention experience and acceptability at follow up. The number of messages received by a given phone number was extracted from the program database. We descriptively analyzed the feasibility and acceptability data and compared the change in MNCH knowledge between baseline and follow-up measures using the McNemar Chi square test. RESULTS: Overall, 895 women were enrolled in the MAMA program. Data from 453/625 women (72.5% of the pretest sample) who received voice (n=302) or text (n=151) messages, and 276/427 men (64.6% of the pretest sample) who received voice (n=185) or text (n=91) messages contributing data at both time points were analyzed. At follow up, 699/729 (95.9%) participants were still enrolled in the MAMA program; voice message and SMS text messaging subscribers received 43 and 69 messages on average over the 6-month period, respectively. Participants who were voice message subscribers and female participants more commonly reported missing messages compared with the text message subscribers and men; predominant reasons for missed messages were the subscribers being busy with chores or not having their shared phone with them. Over 90% of men and women reported experiencing benefits from the program, mainly increased knowledge, and 226/453 (49.9%) of the female participants reported referring someone else to the program. Most of the participants (377/453, 83.2% women and 258/276, 93.5% men) believed it was beneficial to include husbands in the program. Joint decision making regarding maternal and child health care increased overall. The proportions of participants with correct knowledge significantly increased for all but one MNCH measure at follow up. CONCLUSIONS: This assessment indicates that the pilot MAMA program is feasible and acceptable in the Afghan context. Further research should be conducted to determine whether program participation leads to improved MNCH knowledge, health practices, and health service utilization in this fragile setting prior to larger scale up.

Adapting a health video library for use in Afghanistan: provider-level acceptability and lessons for strengthening operational feasibility.

BACKGROUND: Community health workers (CHWs) in Afghanistan are a critical care extender for primary health services, including reproductive, maternal, neonatal, and child health (RMNCH) care. However, volunteer CHWs face challenges including an ever-expanding number of tasks and insufficient time to conduct them. We piloted a health video library (HVL) intervention, a tablet-based tool to improve health promotion and counseling by CHWs. We qualitatively assessed provider-level acceptability and operational feasibility. METHODS: CHWs implemented the HVL pilot in three rural districts of Balkh, Herat, and Kandahar provinces. We employed qualitative methods, conducting 47 in-depth interviews (IDIs) with male and female CHWs and six IDIs with community health supervisors. We used semi-structured interview guides to explore provider perceptions of program implementation processes and solicit feedback on how to improve the HVL intervention to inform scale-up. We conducted a thematic analysis. RESULTS: CHWs reported that the HVL increased time efficiencies, reduced work burden, and enhanced professional credibility within their communities. CHWs felt video content and format were accessible for low literacy clients, but also identified challenges to operational feasibility. Although tablets were considered easy-to-use, certain technical issues required continued support from supervisors and family. Charging tablets was difficult due to inconsistent electricity access. Although some CHWs reported reaching most households in their catchment area for visits with the HVL, others were unable to visit all households due to sizeable populations and gender-related barriers, including women's limited mobility. CONCLUSIONS: The HVL was acceptable and feasible for integration into existing CHW duties, indicating it may improve RMNCH counseling, contributing to increased care-seeking behaviors in Afghanistan. Short-term challenges with technology and hardware can be addressed through continued training and provision of solar chargers. Longer-term challenges, including tablet costs, community coverage, and gender issues, require further consideration with an emphasis on equitable distribution.

Factors associated with reported modern contraceptive use among married men in Afghanistan.

BACKGROUND: Afghanistan has high maternal and infant mortality which is in part driven by high fertility and low modern contraceptive use. Using modern contraceptive methods can reduce maternal and infant mortality, however there are several barriers to modern contraceptive use in Afghanistan. Married men have the potential to hinder or facilitate their wives' contraceptive use. Internally displaced persons (IDP), a growing population in Afghanistan, are rarely included in reproductive health research. We explored whether married men's, including IDPs', gender-related attitudes and other factors were associated with reported modern contraceptive use to inform programming to meet reproductive health needs of married couples. METHODS: Cross-sectional study using data from 885 married men determined to have contraceptive need in seven Afghan provinces. We explored associations between sociodemographic factors, IDP status, wives' involvement in household decision-making and men's attitudes towards intimate partner violence (IPV) with reported modern contraceptive use using logistic regression analysis. RESULTS: Most men (78%) had ≥2 children, 60% reported any formal education, and 30% reported being IDPs. Only 38% of married men and 24% of IDPs with contraceptive need reported using modern contraception with their wives. Most (80% overall, 63% of IDPs) reported their wives' involvement in some/all household decisions, while 47% overall and 57% of IDPs reported IPV was justified in one or more listed circumstances. In bivariate analysis, men responding that IPV was not justified in any listed circumstance were more likely and IDPs less likely to report modern contraceptive use. In multivariable analysis, involvement by wives in household decision-making (AOR 2.57; 95% CI: 1.51, 4.37), owning a radio and/or television (AOR 1.69; 95% CI: 1.10, 2.59), having more children, age, and province of interview were independently associated with reported modern contraceptive use, while IDP status was not. CONCLUSIONS: Our findings reflect positive associations between wives' participation in household decisions and mass media exposure (television/radio ownership) with reported modern contraceptive use. Reproductive health initiatives engaging men to promote communication within couples and through mass media channels may further increase modern contraceptive use and advance Afghanistan's family planning goals. As fewer IDPs owned a radio/television, additional outreach methods should be tested for this group.

Getting health information to internally displaced youth in Afghanistan: can mobile phone technology bridge the gap?

Background: Afghanistan ranks among the most disadvantaged globally for many key reproductive, maternal, newborn and child health (RMNCH) indicators, despite important gains in the past decade. Youth (15 to 24 years) are a key audience for RMNCH information as they enter adulthood, marry and begin families; however, reaching Afghan youth with health information is challenging. Internally displaced persons (IDPs), including youth, experience additional challenges to obtaining health-related information and services. This study measured current and preferred RMNCH information channels to explore the feasibility of using mobile phone technology to provide RMNCH information to IDP youth in Afghanistan. Methods: We conducted a sub-group analysis of survey data from a mixed-methods, cross-sectional, formative assessment to understand current access to RMNCH information. The target population for this analysis includes 15-25-year-old male and female IDP youth from three Afghan Provinces. Survey data were collected using a structured questionnaire administered through face-to-face interviews. Data were analyzed descriptively. Results: A total of 450 IDP youth were surveyed in the three provinces (225 male and 225 female). Access to RMNCH information outside of health facilities was limited. Mobile phone ownership was nearly universal among male participants, yet considerably lower among females; nearly all participants without personal phones reported access to phones when needed. Although few participants spontaneously mentioned mobile phones as a preferred source of RMNCH information, most male and female respondents reported they would be very or somewhat likely to use a free, mobile-phone-based system to access such information if offered. Conclusions: Given widespread access and considerable interest voiced by participants, mobile phones may be a viable way to reach IDP youth with important RMNCH health information in this fragile setting. Interventions should be designed and pilot-tested to identify the most appropriate platforms and information content and to further document feasibility and acceptability.

Dimethylarginine dimethylaminohydrolase-2 deficiency promotes vascular regeneration and attenuates pathological angiogenesis.

Ischemia-induced angiogenesis is critical for tissue repair, but aberrant neovascularization in the retina causes severe sight impairment. Nitric oxide (NO) has been implicated in neovascular eye disease because of its pro-angiogenic properties in the retina. Nitric oxide production is inhibited endogenously by asymmetric dimethylarginines (ADMA and L-NMMA) which are metabolized by dimethylarginine dimethylaminohydrolase (DDAH) 1 and 2. The aim of this study was to determine the roles of DDAH1, DDAH2, ADMA and L-NMMA in retinal ischemia-induced angiogenesis. First, DDAH1, DDAH2, ADMA and L-NMMA levels were determined in adult C57BL/6J mice. The results obtained revealed that DDAH1 was twofold increased in the retina compared to the brain and the choroid. DDAH2 expression was approximately 150 fold greater in retinal and 70 fold greater in choroidal tissue compared to brain tissue suggesting an important tissue-specific role for DDAH2 in the retina and choroid. ADMA and L-NMMA levels were similar in the retina and choroid under physiological conditions. Next, characterization of DDAH1(+/-) and DDAH2(-/-) deficient mice by in vivo fluorescein angiography, immunohistochemistry and electroretinography revealed normal neurovascular function compared with wildtype control mice. Finally, DDAH1(+/-) and DDAH2(-/-) deficient mice were studied in the oxygen-induced retinopathy (OIR) model, a model used to emulate retinal ischemia and neovascularization, and VEGF and ADMA levels were quantified by ELISA and liquid chromatography tandem mass spectrometry. In the OIR model, DDAH1(+/-) exhibited a similar phenotype compared to wildtype controls. DDAH2 deficiency, in contrast, resulted in elevated retinal ADMA which was associated with attenuated aberrant angiogenesis and improved vascular regeneration in a VEGF independent manner. Taken together this study suggests, that in retinal ischemia, DDAH2 deficiency elevates ADMA, promotes vascular regeneration and protects against aberrant angiogenesis. Therapeutic inhibition of DDAH2 may therefore offer a potential therapeutic strategy to protect sight by promoting retinal vascular regeneration and preventing pathological angiogenesis.

Von Hippel-Lindau protein in the RPE is essential for normal ocular growth and vascular development.

Molecular oxygen is essential for the development, growth and survival of multicellular organisms. Hypoxic microenvironments and oxygen gradients are generated physiologically during embryogenesis and organogenesis. In the eye, oxygen plays a crucial role in both physiological vascular development and common blinding diseases. The retinal pigment epithelium (RPE) is a monolayer of cells essential for normal ocular development and in the mature retina provides support for overlying photoreceptors and their vascular supply. Hypoxia at the level of the RPE is closely implicated in pathogenesis of age-related macular degeneration. Adaptive tissue responses to hypoxia are orchestrated by sophisticated oxygen sensing mechanisms. In particular, the von Hippel-Lindau tumour suppressor protein (pVhl) controls hypoxia-inducible transcription factor (HIF)-mediated adaptation. However, the role of Vhl/Hif1a in the RPE in the development of the eye and its vasculature is unknown. In this study we explored the function of Vhl and Hif1a in the developing RPE using a tissue-specific conditional-knockout approach. We found that deletion of Vhl in the RPE results in RPE apoptosis, aniridia and microphthalmia. Increased levels of Hif1a, Hif2a, Epo and Vegf are associated with a highly disorganised retinal vasculature, chorioretinal anastomoses and the persistence of embryonic vascular structures into adulthood. Additional inactivation of Hif1a in the RPE rescues the RPE morphology, aniridia, microphthalmia and anterior vasoproliferation, but does not rescue retinal vasoproliferation. These data demonstrate that Vhl-dependent regulation of Hif1a in the RPE is essential for normal RPE and iris development, ocular growth and vascular development in the anterior chamber, whereas Vhl-dependent regulation of other downstream pathways is crucial for normal development and maintenance of the retinal vasculature.
