The widespread adoption of mobile phones (MPs) presents the possibility of creating employment and self‐employment opportunities. Although several studies have documented the impact of MPs on income, the link between MP ownership and poverty reduction channeled by income diversification has not been fully explored. This paper aims to examine this relationship using nationally representative panel data and fixed effect models to account for confounding factors and unobserved heterogeneity. Results indicate that MP ownership is associated with increased income diversification, particularly through on‐farm and off‐farm self‐employment, as well as non‐earned income. This relationship is more pronounced in households with lower levels of education and deprived areas. In addition, owning a MP is also found to decrease poverty via income diversification. Therefore, policies aimed at enhancing access to mobile technologies could create a resilient income portfolio by decreasing transaction costs and improving market efficiency, ultimately mitigating poverty in rural regions.

Background: In Bangladesh, pharmacy-purchased oral rehydration solution (ORS) is often used to treat diarrhea, including cholera. Over-the-counter sales have been used for epidemiologic surveillance in the past, but rarely, if ever, in low-income countries. With few early indicators for cholera outbreaks in endemic areas, diarrhea-related product sales may serve as a useful surveillance tool. Methodology/Principal Findings: We tracked daily ORS sales at 50 pharmacies and drug-sellers in an urban Bangladesh community of 129,000 for 6-months while simultaneously conducting surveillance for diarrhea hospitalizations among residents. We developed a mobile phone based system to track the sales of ORS and deployed it in parallel with a paper-based system. Our objectives were to determine if the mobile phone system was practical and acceptable to pharmacists and drug sellers, whether data were reported accurately compared to a paper-based system, and whether ORS sales were associated with future incidence of cholera hospitalizations within the community. We recorded 47,215 customers purchasing ORS, and 315 hospitalized diarrhea cases, 22% of which had culture-confirmed cholera. ORS sales and diarrhea incidence were independently associated with the mean daily temperature; therefore both unadjusted and adjusted models were explored. Through unadjusted cross-correlation statistics and generalized linear models, we found increases in ORS sales were significantly associated with increases in hospitalized diarrhea cases up to 9-days later and hospitalized cholera cases up to one day later. After adjusting for mean daily temperature, ORS was significantly associated with hospitalized diarrhea two days later and hospitalized cholera one day later. Conclusions/Significance: Pharmacy sales data may serve as a feasible and useful surveillance tool. Given the relatively short lagged correlation between ORS sales and diarrhea, rapid and accurate sales data are key. More work is needed in creating actionable algorithms that make use of this data and in understanding the generalizability of our findings to other settings. [ABSTRACT FROM AUTHOR]

In the age of globalization and ICTs revolution, conventional media are playing sine qua non role in providing news, information services, and entertainment. Besides, in some countries, community radios (hereafter CRs) are contributing to positive changes in grassroots governance and development. Based on a reality, this paper tries to unravel the following research objectives i.e. i) to get an overview of the program contents of the community radios in Bangladesh; ii) to identify the profiles of the listeners of the CRs in Bangladesh. In a bid to achieve that a mixed method approach was followed. For quantitative data, survey method was used which was followed by some qualitative tools in order to achieve triangulation in research. The findings reveal that there are 18 community radios in Bangladesh and they are providing all sorts of development information at the grassroots. It was found that most of listeners both comprised of male and female were very young and 44% of them were students. A 40% of the respondents have SSC and above level of education. A 70% listeners used to listen CRs using mobile phone. The contents of the programmes of the CRs included a wide range of developmental issues i.e. agriculture, fisheries, livestock, climate change, disaster mitigation, women empowerment, education, news and newspaper, entertainment with music and drama, special programmes of national and international days, learning English, beautification and cooking, programmes for children and minority people. Through their diverse programmes these CRs are providing lots development services to the grassroots societies. [ABSTRACT FROM AUTHOR]

Background: The undergraduate student population has been actively studied in digital mental health research. However, the existing literature primarily focuses on students from high-income nations, and undergraduates from limited-income nations remain understudied. Objective: This study aims to identify the broader social determinants of mental health among undergraduate students in Bangladesh, a limited-income nation in South Asia; study the manifestation of these determinants in their day-to-day lives; and explore the feasibility of self-monitoring tools in helping them identify the specific factors or relationships that affect their mental health. Methods: We conducted a 21-day study with 38 undergraduate students from 7 universities in Bangladesh. We conducted 2 semistructured interviews: one prestudy and one poststudy. During the 21-day study, participants used an Android app to self-report and self-monitor their mood after each phone conversation. The app prompted participants to report their mood after each phone conversation and provided graphs and charts so that the participants could independently review their mood and conversation patterns. Results: Our results show that academics, family, job and economic condition, romantic relationship, and religion are the major social determinants of mental health among undergraduate students in Bangladesh. Our app helped the participants pinpoint the specific issues related to these factors, as the participants could review the pattern of their moods and emotions from past conversation history. Although our app does not provide any explicit recommendation, the participants took certain steps on their own to improve their mental health (eg, reduced the frequency of communication with certain persons). Conclusions: Although some of the factors (eg, academics) were reported in previous studies conducted in the Global North, this paper sheds light on some new issues (eg, extended family problems and religion) that are specific to the context of the Global South. Overall, the findings from this study would provide better insights for researchers to design better solutions to help the younger population from this part of the world. [ABSTRACT FROM AUTHOR]

Traditional approaches to travel behaviour modelling primarily rely on household travel survey data, which is expensive to collect, resulting in small sample sizes and infrequent updates. Furthermore, such data is prone to reporting errors which can lead to biased parameter estimates and subsequently incorrect predictions. On the other hand, mobile phone call detail records (CDRs), which report the timestamped locations of mobile communication events, have been successfully used in the context of generating travel patterns. However, due to their anonymous nature, such records have not been widely used in developing mathematical models establishing the relationship between the observed travel behaviour and influencing factors such as the attributes of the alternatives and the decision makers. In this paper, we propose a joint modelling framework that utilises the advantages offered by both travel survey data and low-cost CDR data to optimise the prediction capacity of traditional trip generation models. In this regard, we develop a model that jointly explains the reported trips for each individual in the household survey data and ensures that the aggregated zonal trip productions are close to those derived from CDR data. This framework is tested using data from Dhaka. Bangladesh consisting of household survey data (65,419 persons in 16,750 households), mobile phone CDR data (over 600 million records generated by 6.9 million users), and aggregate census data. The model results show that the proposed framework improves the spatial and temporal transferability of the joint models over the base model which relies on household travel survey data alone. This serves as a proof-of-concept that augmenting travel survey data with mobile phone data holds significant promise for the travel behaviour modelling community, not only by saving the cost of data collection, but also improving the prediction capability of the models.

The farmers’ community in Bangladesh is one of the most deprived ones in terms of economy and access to social facilities. An agricultural market information service (AMIS) can be one of the important tools for reducing such social inequality by integrating the farmers with their markets more efficiently. Following the failure of a web-based AMIS initiated by the Government of Bangladesh and considering the wide availability of cellular networks, a mobile phone based AMIS was implemented on a pilot basis in some remote villages in Bangladesh. This paper evaluates the efficiency and effectiveness of this mobile service in terms of users, technology, process and facilitating conditions in a rural context. In general this is an interpretive case study as well as an evaluation research which is based on two small scale surveys and observations. Based on a literature review, a conceptual model is also applied for a systematic evaluation. Findings show that effectiveness of a rural e-service depends on the design and delivery of the service in accordance with the individual’s information needs, adaptive technologies with easy accessibility within a given infrastructure, affordable services with a rational business model, adequate awareness and efficient communication with the respective community.

The advent of cheap smartphones in rural areas across the globe presents an opportunity to change the mode with which researchers engage hard-to-reach populations. In particular, smartphones allow researchers to connect with respondents more frequently than standard household surveys, opening a new window into important short-term variability in key measures of household and community wellbeing. In this paper, we present early results from a pilot study in rural Bangladesh using a ‘microtasks for micropayments’ model to collect a range of community and household living standards data using Android smartphones. We find that more frequent task repetition with shorter recall periods leads to more inclusive reporting, improved capture of intra-seasonal variability, and earlier signals of events such as illness. Payments in the form of mobile talk time and data provide a positive development externality in the form of expanded access to mobile internet and social networks. Taken to scale, programs such as this have potential to transform data collection in rural areas, providing near-real-time windows into the development of markets, the spread of illnesses, or the diffusion of ideas and innovations.

Using household survey data from off-grid regions of rural Bangladesh, this study attempts to assess the impacts of mobile phone use on household welfare and women's empowerment. Using two propensity score-based weighted regressions (IPW and AIPW), this study finds that mobile phone use increases household income (3–10 percent) from different sources, such as small businesses and remittances; improves women's empowerment; and facilitates consumption smoothing during periods of shocks. Thus, favorable policies on investment in mobile telephone technologies, tariffs on talk time and internet usage, and mobile innovations, such as mobile financial services could reduce communication bottlenecks and digital divide in rural lagging regions that will help achieve a balanced regional development. Simultaneously, policies to avoid adverse impact of mobile phone usage should also be in place. [ABSTRACT FROM AUTHOR]

This study investigates the impact of Information and Communications Technology (ICT) on economic growth (gross domestic product) for member countries of South Asian Association for Regional Cooperation (SAARC) using annual data for the period 1990–2014. The study has employed augmented Cobb–Douglas production function by incorporating ICT along with capital and labor. We have taken teledensity (number of fixed and mobile phones per 10,000 people) as the proxy of ICT. This study has included only four SAARC countries (Bangladesh, India, Sri Lanka, and Pakistan) due to data constraints. Our findings reveal a positive and statistically significant effect of ICT on economic growth using panel data techniques. However, the impact of ICT on economic growth is highest for India followed by Sri Lanka, Bangladesh, and Pakistan respectively. This study has crucial policy implications for SAARC countries as they have started giving due significance to the issues related to ICT these years. [ABSTRACT FROM AUTHOR]

This research looked on the gender gap in smartphone app usage and the impact of gender on smartphone-based social networks and social support in Bangladesh, a south Asian country. The sample of smartphone-owning 250 college/university students was surveyed online. Results showed that women were more likely to utilize a smartphone's camera than men were, but men were more inclined to make phone calls and use apps developed expressly for smartphones. Moreover, the findings revealed unique behaviors associated with the use of smartphones in the upkeep of interpersonal connections. Women were more likely to think bonding ties enhanced while using smartphones for text communications, whereas men were more inclined to believe more bridge links expanded. According to these findings, women tend to be more likely to use their cellphones to improve already-strong connections, whilst men appear to be more prone to use them to boost already-weak social relationships.

Consumers are becoming more interdependent and open as a result of globalization. Because of the idea of globalization, branding is essential to take into account from both the marketing and consumer viewpoints. The current study intends to determine Bangladeshi customers' preferences for cell phone brands based on global versus local perspectives and to comprehend the influencing factors and cell phone features that could affect users' purchasing decisions. A structured questionnaire was used to survey 850 consumers selected through a simple random sampling technique for the study, and 593 of their responses were deemed sufficient to continue the research. According to the study's findings, customers favored the Android operating system and the Samsung brand the most. The majority of consumers believed that having a cell phone's 'convenient' usage was its best feature. The study also identified a range of preferred budgets for a new cell phone. Eventually, a new measurement model for cell phone brand preference factors among Bangladeshi consumers was excavated by the study. Only four of the nine items selected for measurement in the study were sufficient for validating the model. The study's inability to pinpoint any local ethnocentrism for brand preference was one of its flaws. The study will contribute and originate the value with novel and significant implications for cell phone consumers to choose their preferred brands with quality of service, cell phone brand marketers, telecom service providers, payment gateway service providers, and their support systems, including producers, supply chain and industry experts, before and after-sale service providers, brand promoters, stakeholders, policymakers, and governments of various developing and developed countries to build up and implement brand strategies and policies in the global cell phone device and internet-connected digitalized era. As a result, consumers can achieve their greater perceived brand value, ensuring their desired level of satisfaction with highly cognitive brand preferences, brand trust, and brand loyalty to their expected cell phone brands.

Making farmers in developing countries more informed about market opportunities is generally considered an important step toward development of the agricultural sector and increasing individual farmers' income. Mobile phones are a useful technology for delivering such information, but are farmers ready? According to Sen [Development as freedom. In J. Ezer (Ed.), Gandhi's third assassination: Information and communication technology education in India (pp. 201-212)], human capability is the basic driver for development. This paper investigates, by means of a survey (n = 420) to farmers in rural Bangladesh, what factors affect mobile phone ownership and use and what professional information is asked for. We find that access is very high, to a large extent through community use. Neither education nor income is a determining factor, but 'modernity' - being young and/or having children - is. Even the very poor have access. Attitudes are very positive not just to the phones, but also to using them for professional information services. Hence, human capacity for development is there, as is technology. What is still lacking is the useful services adapted to the rural usage patterns and social context. [ABSTRACT FROM AUTHOR]

This paper describes how distance educations in developing countries can enhance interactivity by means of information and communication technologies. It is argued that e-learning involves a shift in the educational structure from traditional transmission of knowledge to interactive creation of knowledge. Our case studies are two distance educations in Bangladesh and Sri Lanka that use different technologies for implementing interactivity; Internet and computers in one case and video and mobile phones in the other. The findings are analyzed based on Structuration Theory and we compare the two approaches based on emerging norms and beliefs. Findings from both cases show the concurrent enactment of both the transmission and the interactive structure. Whereas peer collaboration and the use of self-assessment tools make students take more ownership of their learning, we also found the idea of a classroom with an instructive teacher to be deeply rooted in the students' minds.

The authors' aim in this study was to investigate the factors influencing the adoption of mHealth services between the young aged and the elderly female in Bangladesh. Using the extended Technology Acceptance Model (TAM) with three additional latent variables, i.e., perceived reliability, price value and technology anxiety, the proposed model was empirically examined based on the required data from a total survey of 542 respondents. Researchers revealed that perceived usefulness had significant impact on behavioral intention for both the young aged and the elderly female but perceived ease of use was insignificant for both groups. Perceived reliability and price value were found to have strong impact on actual usage. But the effect of technology anxiety was significant for elderly female but insignificant for young-aged female due to age characteristics. Therefore, this study is the first initiative to compare the adoption factors between young aged and elderly female in Bangladesh. [ABSTRACT FROM AUTHOR]

The program entitled "English in Action (EIA)", 9 year period DFID funded project in Bangladesh, was launched in 2008, for the desire to bring a change in the learning of English language. EIA works to reach a total of 25 million primary and secondary students and adult learners through communicative language learning techniques and the use of ICT, textbooks and supplementary materials in an innovative way. The project has been running, with the help of BBC World Service Trust and BBC Learning English, the program entitled "BBC Janala", an initiative that is providing English language lessons to citizens via their mobile phones as part of the wider English in Action program in Bangladesh. Survey research found that women are particularly interested in learning by mobile (especially given its "any time, any place" nature). That means, it is absolutely being implemented as a non-formal education (NFE) under the Open and Distance Learning (ODL) mode what is known as Open Non-formal Education (ONFE). BBC Janala allows Bangladeshis to access short (2-3 minute) audio lessons through a simple voice call by calling a four digit short code. The program has been a real challenge as it has the ability to address the need of students with an effective integration of ICT to support learning. This paper discusses how one increasingly ubiquitous ICT device -the mobile phone- has become increasingly relevant to learners in Bangladesh, in various ways and contexts. [ABSTRACT FROM AUTHOR]

Background: This is the first study to examine the costs of conducting a mobile phone survey (MPS) through interactive voice response (IVR) to collect information on risk factors for noncommunicable diseases (NCD) in three low- and middle-income countries (LMIC); Bangladesh, Colombia, and Uganda. Methods: This is a micro-costing study conducted from the perspective of the payer/funder with a 1-year horizon. The study evaluates the fixed costs and variable costs of implementing one nationally representative MPS for NCD risk factors of the adult population. In this costing study, we estimated the sample size of calls required to achieve a population-representative survey and associated incentives. Cost inputs were obtained from direct economic costs incurred by a central study team, from country-specific collaborators, and from platform developers who participated in the deployment of these MPS during 2017. Costs were reported in US dollars (USD). A sensitivity analysis was conducted assessing different scenarios of pricing and incentive strategies. Also, costs were calculated for a survey deployed targeting only adults younger than 45 years. Results: We estimated the fixed costs ranging between $47,000 USD and $74,000 USD. Variable costs were found to be between $32,000 USD and $129,000 USD per nationally representative survey. The main cost driver was the number of calls required to meet the sample size, and its variability largely depends on the extent of mobile phone coverage and access in the country. Therefore, a larger number of calls were estimated to survey specific harder-to-reach sub-populations. Conclusion: Mobile phone surveys have the potential to be a relatively less expensive and timely method of collecting survey information than face-to-face surveys, allowing decision-makers to deploy survey-based monitoring or evaluation programs more frequently than it would be possible having only face-to-face contact. The main driver of variable costs is survey time, and most of the variability across countries is attributable to the sampling differences associated to reaching out to population subgroups with low mobile phone ownership or access.

This article uses the 4A framework (awareness, acceptability, affordability, accessibility) to examine the impact of marketing activities on market development (i.e., access to markets, access to people) and value creation (financial value and relationship value) in low-income segments in emerging markets. Using cross-national survey data spanning mobile phone users in five emerging Asian markets (countries: Bangladesh, India, Pakistan, Sri Lanka, and Thailand), the study findings provide empirical support for the 4A framework for small farmers and business persons (i.e., low-income entrepreneurs) in these markets. The study uniquely contributes to the base of pyramid literature in emerging markets since the 4A marketing framework has not been studied for its effectiveness on micro-entrepreneurs so far. This article also contributes to research and practice by showing how market development and value creation go hand-in-hand for micro-entrepreneurs in emerging markets. [ABSTRACT FROM AUTHOR]

Background: Home exposure to secondhand smoke (SHS) is highly prevalent amongst pregnant women in low- and middle-income countries like India and Bangladesh. The literature on the efficacy of behaviour change interventions to reduce home exposure to SHS in pregnancy is scarce. Methods: We employed a theory and evidence-based approach to develop an intervention using pregnant women as agents of change for their husband's smoking behaviours at home. A systematic review of SHS behaviour change interventions led us to focus on developing a multicomponent intervention and informed selection of behaviour change techniques (BCTs) for review in a modified Delphi survey. The modified Delphi survey provided expert consensus on the most effective BCTs in reducing home exposure to SHS. Finally, a qualitative interview study provided context and detailed understanding of knowledge, attitudes and practices around SHS. This insight informed the content and delivery of the proposed intervention components. Results: The final intervention consisted of four components: a report on saliva cotinine levels of the pregnant woman, a picture booklet containing information about SHS and its impact on health as well strategies to negotiate a smoke-free home, a letter from the future baby to their father encouraging him to provide a smoke-free home, and automated voice reminder and motivational messages delivered to husbands on their mobile phone. Intervention delivery was in a single face-to-face session with a research assistant who explained the cotinine report, discussed key strategies for ensuring a smoke-free environment at home and practised with pregnant women how they would share the booklet and letter with their husband and supportive family members. Conclusion: A theory and evidence-based approach informed the development of a multicomponent behaviour change intervention, described here. The acceptability and feasibility of the intervention which was subsequently tested in a pilot RCT in India and Bangladesh will be published later. [ABSTRACT FROM AUTHOR]

The main objective of this study was to assess the machine vision (MV) techniques to classify six Asian rice varieties commonly named as Kachi-Kainat, Kachi-Toota, Kainat-Pakki, Super-Basmati-Kachi, Super-Basmati-Pakki, and Super-Maryam-Kainat (A1, A2, A3, A4, A5, and A6), mainly cultivated in Pakistan, China, India, Bangladesh, and neighboring countries. The sample of each selected rice variety contained 1800 grains, giving a total of 10800 (1800 × 6) grain samples. A cell phone camera captured the actual field digital images dataset in an open climate. All the captured images were enhanced and converted into the standard 8-bit gray-scale format. Six radius-based non-overlapping regions of interest (ROI's) were taken on each captured image inducing a total of 3600 (6 × 600) ROI's image dataset. We have extracted Binary (B), Histogram (H), and Texture (T) features from each image. We converted these forty-three features for each image into 154800 (43 × 3600) feature vector (FV) space to discriminate rice varieties. After optimizing the FV, five MV classifiers, namely; LMT Tree (LMT-T), Meta Classifier via Regression (MCR), Meta Bagging (MB), Tree J48 (T-J48), and Meta Attribute Select Classifier (MAS-C), were deployed attaining the classification accuracies as 97.4%, 97.0%, 96.3%, 95.74%, and 95.2%, respectively. The maximum overall accuracy (MOA) observed was 97.4% by LMT-Tree. [ABSTRACT FROM AUTHOR]

The purpose of this article is to provide lessons from the field about an Information and Communication Technology for Development (ICT4D) project (Participatory Research and Ownership With Technology, Information and Change [PROTIC]) concerned with the use of mobile phones by women in remote villages in Bangladesh. The Bangladeshi government considers that the role of ICT in social and economic transformation is significant for the country's development. International nongovernmental organizations (NGOs) also regard ICT as important but are challenged as how to use them effectively for their programs and how to deal with long-term sustainability, digital divides, gender, and cultural issues. This article considers the PROTIC project as a modeling force for innovation and pressure on established sociotechnical structures. In this analysis, we follow what Donner defines as the "interrelationship" perspective, as applied to ICT4D. In particular, the notions of niche, regime, and landscape will be used to frame the changes that a village-level project may activate or respond to at the micro, meso, and macro levels of sociotechnical interaction. A mixed methods approach has been implemented during the 4 years of the project to monitor its outcomes, including interviews with project participants, reports of monthly consultations and training with villagers, extensive surveys, analysis of the Facebook profile of the project, and field notes and interviews with local NGOs and international NGO staff. Results show that the women villagers have undergone a transformation in attitudes, skills, and practices associated with mobile phone use. Transformations at individual and community niche levels have in turn influenced the conceptual framework of local and international NGOs and have also contributed to the reorientation of other regime actors, such as universities, major NGOs, and the government. Methodological constraints as well as the complexity of conducting international fieldwork with multiple actors will also be discussed. [ABSTRACT FROM AUTHOR]

Health policies and public health studies in Bangladesh primarily focus on physical aspects of health, thus creating a gap in the literature regarding the assessment of the emotional-social environment for children and their developmental vulnerabilities. Interactions though literacy activities, such as shared reading times between child and parents, are possible ways to address the developmental and cognitive needs of children. This study explores the district-wise presence of books for children (aged 0–4 years) in households and identifies vulnerable households by exploring the association between sociodemographic status and household book ownership. The Bangladesh Multiple Indicator Cluster Survey 2012–13 was used to map the spatial heterogeneity of average availability of children's books, which revealed that ownership of age-appropriate books was clustered around divisional cities, with one exception. Around 65% of the households did not have any suitable books for children. The presence of children's books was significantly (p <.005) associated with children's age, mother's age and education, financial status of the household, education of the head of the house, mother's mobile phone ownership, and mother's access to media (newspaper and television). Parents in high-income households and with highly educated mothers were nearly three times more likely to own children's books. Similarly, parents in a household with the mother having a mobile phone were 42% more likely to own children's books. The findings suggest that a household's lack of financial capacity to purchase books, the role of public health media in promoting the mother's awareness of the need for children's books, and a lack of understanding of children's cognitive developmental needs could be more effectively addressed in Bangladesh.

Access to information and communication technology (ICT) has been considered crucial to alleviate poverty and improve food security of rural households. The mobile phone is an ICT that is widely used by rural households in developing countries. This study examines the determinants of mobile phone adoption using survey data of vulnerable rural households in Bangladesh, a developing country; the study empirically assesses the income hypothesis of mobile phone adoption in particular. Four alternative specifications of the model are developed to test the stability and robustness of the estimates. The study finds rural households have heterogeneous access to ICT such as radio, TV, computer and the Internet except mobile phone. Our estimated Gini coefficient indicates high income inequality among the rural households. The model results suggest that household income positively influences mobile phone adoption. However, the impact is not statistically significant. Other factors such as respondents' age, education and farm category are statistically significant influences on mobile phone adoption. An increasing use of mobile phones is likely to enhance the sharing of valuable information among rural households for the better management of their livelihoods and improved farming decisions.

Objective: We examined the incremental cost-effectiveness between two mHealth programs, implemented from 2011 to 2015 in rural Bangladesh: (1) Comprehensive mCARE package as an intervention group and (2) Basic mCARE package as a control group. Methods: Both programs included a core package of census enumeration and pregnancy surveillance provided by an established cadre of digitally enabled community health workers (CHWs). In the comprehensive mCARE package, short message service (SMS) and home visit reminders were additionally sent to pregnant women (n = 610) and CHWs (n = 70) to promote the pregnant women’s care-seeking of essential maternal and newborn care services. Economic costs were assessed from a program perspective inclusive of development, start-up, and implementation phases. Effects were calculated as disability adjusted life years (DALYs) and the number of newborn deaths averted. For comparative purposes, we normalized our evaluation to estimate total costs and total newborn deaths averted per 1 million people in a community for both groups. Uncertainty was assessed using probabilistic sensitivity analyses with Monte Carlo simulation. Results: The addition of SMS and home visit reminders based on a mobile phone-facilitated pregnancy surveillance system was highly cost effective at a cost per DALY averted of $31 (95% uncertainty range: $19–81). The comprehensive mCARE program had at least 88% probability of being highly cost-effective as compared to the basic mCARE program based on the threshold of Bangladesh’s GDP per capita. Conclusion: mHealth strategies such as SMS and home visit reminders on a well-established pregnancy surveillance system may improve service utilization and program cost-effectiveness in low-resource settings.

Introduction: Increased mobile phone subscribership in low- and middle-income countries (LMICs) provides novel opportunities to track population health. The objective of this study was to examine reliability of data in comparing participant responses collected using two mobile phone survey (MPS) delivery modalities, computer assisted telephone interviews (CATI) and interactive voice response (IVR) in Bangladesh (BGD) and Tanzania (TZA). Methods: Using a cross-over design, we used random digit dialing (RDD) to call randomly generated mobile phone numbers and recruit survey participants to receive either a CATI or IVR survey on non-communicable disease (NCD) risk factors, followed 7 days later by the survey mode not received during first contact; either IVR or CATI. Respondents who received the first survey were designated as first contact (FC) and those who consented to being called a second time and subsequently answered the call were designated as follow-up (FU). We used the same questionnaire for both contacts, with response options modified to suit the delivery mode. Reliability of responses was analyzed using the Cohen’s kappa statistic for percent agreement between two modes. Results: Self-reported data on demographic characteristics and NCD behavioral risk factors were collected from 482 (CATI-FC) and 653 (IVR-FC) age-eligible and consenting respondents in BGD, and from 387 (CATI-FC) and 674 (IVR-FC) respondents in TZA respectively. Survey follow-up rates were 30.7% (n = 482) for IVR-FU and 53.8% (n = 653) for CATI-FU in BGD; and 42.4% (n = 387) for IVR-FU and 49.9% (n = 674) for CATI-FU in TZA respectively. Overall, there was high consistency between delivery modalities for alcohol consumption in the past 30 days in both countries (kappa = 0.64 for CATI→IVR (BGD), kappa = 0.54 for IVR→CATI (BGD); kappa = 0.66 for CATI→IVR (TZA), kappa = 0.76 for IVR→CATI (TZA)), and current smoking (kappa = 0.68 for CATI→IVR (BGD), kappa = 0.69 for IVR→CATI (BGD); kappa = 0.39 for CATI→IVR (TZA), kappa = 0.50 for IVR→CATI (TZA)). There was moderate to substantial consistency in both countries for history of checking for hypertension and diabetes with kappa statistics ranging from 0.43 to 0.67. There was generally lower consistency in both countries for physical activity (vigorous and moderate) with kappa statistics ranging from 0.10 to 0.41, weekly fruit and vegetable with kappa ranging from 0.08 to 0.45, consumption of foods high in salt and efforts to limit salt with kappa generally below 0.3. Conclusions: The study found that when respondents are re-interviewed, the reliability of answers to most demographic and NCD variables is similar whether starting with CATI or IVR. The study underscores the need for caution when selecting questions for mobile phone surveys. Careful design can help ensure clarity of questions to minimize cognitive burden for respondents, many of whom may not have prior experience in taking automated surveys. Further research should explore possible differences and determinants of survey reliability between delivery modes and ideally compare both IVR and CATI surveys to in-person face-to-face interviews. In addition, research is needed to better understand factors that influence survey cooperation, completion, refusal and attrition rates across populations and contexts. [ABSTRACT FROM AUTHOR]

Background: In Bangladesh, similar to its other South Asian counterparts, shortage of health workers along with inadequate infrastructure constitute some of the major obstacles for the equitable provision of reproductive healthcare services, particularly among the marginalized and underserved neighbourhoods. However, given the rapidly expanding broadband communication and mobile phone market in the country, the application of eHealth and mHealth technologies offer a window of opportunities to minimise the impact of socioeconomic barriers and promote the utilization of maternal healthcare services thereby. In the present study we aimed to investigate 1) the prevalence of usage of mobile phones for seeking childbirth services, 2) neighbourhood and socioeconomic disparities in the use, and 3) association between using mobile phones and the uptake of postnatal care among mothers and neonates.Methods: Data for the present study came from Bangladesh Urban Health Survey 2013. Study subjects were 9014 married women aged between 15 and 49 years.Results: The overall rate of use of mobile phone was highest in City Corporation non-Slum areas (16.2%) and lowest in City Corporation Slum areas (7.4%). The odds of using mobile for seeking childbirth services were significantly higher among those who were living in non-slum areas, and lower among those who never attended school and lived in poorer households. Results also indicated that women in the slum areas who used mobile phone for childbirth service seeking, were 4.3 times [OR = 4.250;95% CI = 1.856-9.734] more likely to receive postnatal care for themselves, and those from outside the city-corporation areas were 2.7 times [OR = 2.707;95% CI = 1.712-4.279] more likely to receive postnatal care for the newborn.Conclusion: Neighbourhood, educational and economic factors were significantly associated with the mobile phone utilization status among urban women. Promoting access to better education and sustainable income earning should be regarded as an integral part to the expansion of mHealth for maternal healthcare seeking behaviour.

Dairy and non-dairy households in chars in northern Bangladesh were compared. About 35% of dairy households earned money by selling milk along with labour. Dairy households owned more land than the non-dairy group. More dairy households (70%) had drinking water and 74% had sanitation facilities, while 49% and 44% non-dairy households had such facilities. The dairy households owned 3065 livestock, of which 946 were cattle; while non-dairy households owned 1915 livestock, including 17 cattle. Average daily income of each dairy household was 129 Taka (US$ 1 = Taka: 56.31), and for non-dairy household it was 109 Taka. Many dairy households had a bicycle (n = 54), radio (n = 59) and cell phone (n = 211), but fewer in the non-dairy had a bicycle (n = 8) and cell phone (n = 43). The livestock are living assets for the flood-prone households and source of daily income. [ABSTRACT FROM AUTHOR]

The emergence of mobile technology offers new opportunities to improve clinical guideline adherence in resource-limited settings. We conducted a clinical pilot study in rural Bangladesh to evaluate the impact of a smartphone adaptation of the World Health Organization (WHO) diarrheal disease management guidelines, including a modality for age-based weight estimation. Software development was guided by end-user input and evaluated in a resource-limited district and sub-district hospital during the fall 2015 cholera season; both hospitals lacked scales which necessitated weight estimation. The study consisted of a 6 week pre-intervention and 6 week intervention period with a 10-day post-discharge follow-up. Standard of care was maintained throughout the study with the exception that admitting clinicians used the tool during the intervention. Inclusion criteria were patients two months of age and older with uncomplicated diarrheal disease. The primary outcome was adherence to guidelines for prescriptions of intravenous (IV) fluids, antibiotics and zinc. A total of 841 patients were enrolled (325 pre-intervention; 516 intervention). During the intervention, the proportion of prescriptions for IV fluids decreased at the district and sub-district hospitals (both p < 0.001) with risk ratios (RRs) of 0.5 and 0.2, respectively. However, when IV fluids were prescribed, the volume better adhered to recommendations. The proportion of prescriptions for the recommended antibiotic azithromycin increased (p < 0.001 district; p = 0.035 sub-district) with RRs of 6.9 (district) and 1.6 (sub-district) while prescriptions for other antibiotics decreased; zinc adherence increased. Limitations included an absence of a concurrent control group and no independent dehydration assessment during the pre-intervention. Despite limitations, opportunities were identified to improve clinical care, including better assessment, weight estimation, and fluid/ antibiotic selection. These findings demonstrate that a smartphone-based tool can improve guideline adherence. This study should serve as a catalyst for a randomized controlled trial to expand on the findings and address limitations. [ABSTRACT FROM AUTHOR]

Background Mobile phone SMS is increasingly used as a means of communication between patients and their healthcare providers in many countries of the world. We investigated mobile phone use and factors associated with willingness-to-pay (WTP) for diabetes SMS among patients with type 2 diabetes in Bangladesh. Methods As part of a randomized controlled study, in 515 patients with type 2 diabetes, socioeconomic status, mobile phone use, WTP for diabetes SMS, anthropometry and HbA1cwere measured. Multivariate regression was used to identify factors associated with WTP. Results The median (interquartile range [IQR]) of WTP for diabetes SMS was 20 (45) Bangladesh Taka (BDT) (1 BDT = 0.013 US$). WTP was significantly higher for males [OR 2.4, 95% CI (1.0-5.7)], patients with household income > 50 000 BDT [4.6(1.1-20.4)] and those with primary education [5.6 (1.2-26.6)] and secondary and higher education [5.2 (1.4-19.6)]. Conclusions The high proportion of mobile phone use and WTP for diabetes SMS are encouraging as possible strategy to use such technologies and deserve further evaluation. [ABSTRACT FROM AUTHOR]

The number of studies focussed on mobile phone usage in the developing world is growing steadily as in the developed world. This study looks at individuals' mobile phone usage behaviour in Bangladesh to measure the effects of the two key factors explained in the theory of reasoned action. The study employs a regression model to predict individuals' behavioural intention where attitude towards behaviour and subjective norms are considered as explanatory variables. The model estimates reveal that both the constructs have significant contributions in anticipating consumers' behavioural intention of mobile phone usage in Bangladesh which complements the application of the theory of reasoned action. The study outlines some policy implications. [ABSTRACT FROM AUTHOR]

Despite a manifold increase in mobile penetration in Bangladesh, a significant number of people still do not own a mobile phone. However, the communication needs of non-owning users (NOUs) are being met by a large number of public mobile telephone kiosks and informal sharing amongst people. Available studies on mobile phones have generally tended to be owner-centric. Few studies have documented how NOUs access and use mobile phones and to what end. As such, very little is known about how mobile phones are formally or informally shared among people or if NOUs are more disadvantaged in terms of use and impact than owners. This study explores mobile phone use by NOUs in two locations in Dhaka city, Bangladesh. Specifically, two dimensions of use are explored: strategic use of mobiles – the ability to reduce cost and maximize utility, and the ability to shape livelihood strategies. In-depth interviews of 15 NOUs and 12 owners were conducted. The findings show that NOUs adopt several innovative strategies for cost reduction. Findings also reveal that mobile use by NOUs has significant impact on facilitating their livelihood strategies. The effect is particularly strong for those who are migrant workers from rural areas.

E-commerce has been seen as a way to reduce friction in the marketplace. It allows larger volumes of transactions to take place than would otherwise be possible in the conventional marketplace, and it effectively expands markets while opening up opportunities for new ones. However , it is heavily dependent on physical infrastructure and other support services; these are often unavailable or inaccessible at the bottom of the pyramid (BoP) in developing markets. The rapid proliferation of mobile phones throughout these markets, along with increasingly affordable services, creates opportunity to take the benefits of such applications to the BoP segment in these markets. This article examines the case of CellBazaar, a mobile-based electronic marketplace (e-marketplace) in Bangladesh, perhaps the first of its kind to reach the BoP in a developing market. It is a real-time collection of classified advertisements accessible even through the most basic mobile phone. Taking CellBazaar as a starting point, this article explores the potential for providing a wider range of e-marketplace services, including secure payment and delivery of the goods/ services traded in a country with a significant BoP population such as Bangladesh; it looks at some of the obstacles that may arise in such a setting and discusses possible solutions.

The purpose of this essay is to: (1) detail how recent trends in philosophical theory have made it possible for philosophers of technology to critically discuss technology transfer; (2) demonstrate that economic standards of assessment are conducive to obscuring the hidden tradeoffs that technological practices, such as mobile phone use in Bangladesh, can engender; and (3) provide the basis of an alternative model that can reflexively addresses dimensions of technology transfer that neo-classical economic accounts occlude.

Cell-phone SMS—Short Message Service—is helping bridge the Digital Divide in developing countries around the world. Beginning in Bangladesh, one of the poorest countries on Earth, and now extending into many other Third World countries, SMS offers synchronous and asynchronous interactive communication in situations where previously there was no communication at all, as between people in jungle villages and government or nongovernmental organization offices in major cities. SMS offers a wide variety of applications from public health to c-commerce. This article describes recent developments mainly in data collection and distance education. [ABSTRACT FROM AUTHOR]
