Background Despite the high usage of mobile phones in daily life in developing countries like Bangladesh, the adoption and usage of mHealth services have been significantly low among the elderly population. When searching previous studies, the researchers have found that no studies have empirically investigated whether the quality of life and service quality are significant for mHealth adoption by elderlies in Bangladesh. Hence, this study aimed to extend the Unified Theory of Acceptance and Use of Technology by adding service quality and the quality of life to empirically find the key factors that influence elderlies’ intention to adopt and use mHealth services in Bangladesh. Methods A face-to-face structured questionnaire survey method was used to collect data from 493 elderlies (aged 60 years and above) in Bangladesh. The data were analyzed with the Structural Equations Modelling (SEM) and Fuzzy Set Qualitative Comparative Analysis (fsQCA). Results SEM results suggested that Social Influence, Hedonic Motivation, Price Value, Habit, and Service Quality had significant impact (p < 0.05) on the elderlies’ behavioral intention to adopt mHealth services. Service Quality, Quality of Life, and elderlies’ Habit were found significant in explaining the Use Behavior of mHealth services. Quality of Life did not show significant (p > 0.05) effect on Behavioral Intention, which is inconsistent with existing literature. In addition, fsQCA findings suggest how the intensity of the influencers may contribute to high versus low m-health behavioral outcomes. Conclusions The findings have significant implications for theory, practice and future research as explained in the paper. The originality of this study is the integration of quality of life and service quality into UTUAT2 to explain the users’ behavioural intention and use behaviour. Overall, the findings may contribute to shaping appropriate policies for designing and implementing mHealth services effectively for elderlies in developing countries.

Background: mHealth (mobile health) has a far-reaching impact on delivering health services to a low-resource and remote population, especially elderlies with regular and emergency health needs in developing nations. Even though the high usage of mobile phones in daily life in developing countries like Bangladesh, adoption, and usage of mHealth services have been significantly low among the elderly population. Hence, this study aimed to identify key factors that influence elderlies’ intention to adopt and use mHealth services by extending the Unified Theory of Acceptance and Use of Technology (UTAUT2) model.Methods: A face-to-face structured questionnaire survey method was used to collect data from 493 elderlies (aged 60 years and above) in Bangladesh. The data were analyzed with the Structural Equations Modelling (SEM) and Fuzzy Set Qualitative Comparative Analysis (fsQCA).Results: SEM results suggested that Social Influence, Hedonic Motivation, Price Value, Habit, and Service Quality had significant impact (p<0.05) on the elderlies’ behavioral intention to adopt mHealth services. Service Quality, Quality of Life, and elderlies’ Habit were found significant in explaining the Use Behavior of mHealth services. Quality of Life did not show significant (p>0.05) effect on Behavioral Intention which is inconsistent with existing literature. In addition, fsQCA findings suggest how the intensity of the influencers may contribute to high vs low m-health behavioral outcomes.Conclusions: The findings have significant implications for theory, practice and future research as explained in the concluding section of the paper. The extension of UTUAT2 in this study would contribute in the literature of mHealth especially considering the fact that elderlies' quality of life is an important determinant of the continued mHealth use behavior. Overall, the findings may contribute to shaping appropriate policies for designing and implementing mHealth services effectively for elderlies in developing countries.

Islamic banking has now become a proven model of banking business worldwide as it offers stable return from both the perspective of assets and capital of a commercial bank. Within a very short span of time, Islamic banks in Bangladesh depicted a commendable growth. This innovative banking mechanism is widely accepted from the bankers as well as customers' standpoint. This study analyzes the impact of some selected bank-specific and macroeconomic variables on the profitability of all the seven Islamic banks in Bangladesh with panel data from 2003 to 2014. The study findings conclude that some of the bank-specific and macroeconomic variables have a significant influence on the profitability of Islamic banks.
