Text messaging to improve retention in hypertension care in Bangladesh

Visit non-attendance is a common barrier to hypertension control in low and middle-income countries (LMICs). We aimed to evaluate the effectiveness of mobile text messaging in improving visit attendance among patients with hypertension in primary healthcare facilities in Bangladesh. A randomized A/B testing study was conducted with two patient groups: (1) patients regularly attending visits (regular patients) and (2) patients overdue for their follow-up clinic visit (overdue patients). Regular patients were randomized into three groups: a cascade of three text reminders, a single text reminder, or no text reminder. Overdue patients were randomized into two groups: a single text reminder or no text reminder. 20,072 regular patients and 12,708 overdue patients were enrolled. Among regular patients, visit attendance was significantly higher in the cascade reminder group and the single reminder group compared to the no reminder group (78.2% and 76.6% vs. 74.8%, p < 0.001 and 0.027, respectively). Among overdue patients, the single reminder group had a 5.8% higher visit attendance compared to the no reminder group (26.5% vs. 20.7%, p < 0.001). The results remained consistent in multivariable analysis; adjusted prevalence ratio (PR) was 1.04 (95% CI 1.02–1.06) for the cascade reminder group and 1.02 (95% CI 1.00–1.05) for the single reminder group among regular patients. The adjusted PR for the single reminder group vs. the no reminder group among overdue patients was 1.23 (95% CI 1.15–1.33). Text message reminders are an effective strategy for improving retention of patients in hypertension treatment in LMICs, especially for patients overdue to care.

A hybrid approach of machine learning algorithms for improving accuracy of social media crisis detection

The use of social media is becoming increasingly important in our day-to-day activities. Platforms for social media are utilised on a daily basis, and it has been seen that young adults make regular use of social media, even while they are in the midst of an emergency scenario. For the purpose of communication, individuals, businesses, and governments all make use of various social media platforms. Through their efforts to establish communication with their loved ones who are residing in regions that have been impacted by disasters, a great number of people are demonstrating their profound concern for the well-being of those individuals. The individuals are looking for a variety of necessities, including food, help, pharmaceuticals, lodging, transportation, and other necessities. It is possible for telecommunication networks to experience a breakdown or become incapable of adequately accommodating a sudden spike in the number of users attempting to connect to the network during times of crisis. There is a widespread use of short messaging service (SMS) mobile text messages in the modern communication landscape. Platforms for social media websites that are accessible online have the potential to effectively regulate the flow of communication. The existence of social media networks that are technologically scalable makes it possible for this to be a feasible option. The usage of a platform that enables communication in both directions has the potential to outperform the efficiency of conventional channels that only transmit information in one direction, such as radio and television, when it comes to crisis situations. The proliferation of network technologies has resulted in an increased emphasis on the examination of the features of network components, the mitigation of the affects of these components, and the rapid restoration of operations in the event of disasters. It is possible to improve the efficiency, dependability, and participatory nature of emergency communication by making use of various social media platforms. Consequently, it is possible to make the observation that crises have become an integral part of the ecosystem of social media in the modern day.

Exercise behaviours and motivation after a first psychotic episode: A digital intervention.

Research has demonstrated that participation in aerobic exercise can have significant beneficial effects across both physical and mental health domains for individuals who are in the early phase of schizophrenia. Despite these notable benefits of exercise, deficits in motivation and a lack of methods to increase engagement are significant barriers for exercise participation, limiting these potentially positive effects. Fortunately, digital health tools have the potential to improve adherence to an exercise program. The present study examined the role of motivation for exercise and the effects of an automated digital text messaging program on participation in an aerobic exercise program. A total of 46 first-episode psychosis participants from an ongoing 12-month randomized clinical trial (Enhancing Cognitive Training through Exercise Following a First Schizophrenia Episode (CT&E-RCT)) were included in an analysis to examine the efficacy of motivational text messaging. Personalized motivational text message reminders were sent to participants with the aim of increasing engagement in the exercise program. We found that participants with higher levels of intrinsic motivation to participate in a text messaging program and in an exercise intervention completed a higher proportion of individual, at-home exercise sessions. In a between groups analysis, participants who received motivational text messages, compared to those who did not, completed a higher proportion of at-home exercise sessions. These results indicate the importance of considering a person's level of motivation for exercise and the potential utility of using individualized and interactive mobile text messaging reminders to increase engagement in aerobic exercise in the early phase of psychosis. We emphasize the need for understanding how individualized patient preferences and needs interplay between intrinsic motivation and digital health interventions for young adults.

Effectiveness of a culturally tailored text messaging program for promoting cervical cancer screening in accra, Ghana: a quasi-experimental trial

IntroductionDespite breakthroughs in cervical cancer detection, resource-constrained countries continue to have a disproportionately high incidence and death rate. Mhealth has been identified as an important tool for increasing cervical cancer screening rates in Sub-Saharan Africa. We determined whether sending Ghanaian women culturally tailored one-way mobile phone SMS text messages about cervical cancer would encourage the uptake of the human papillomavirus (HPV) test.MethodsFrom August to November 2016, 88 women aged 18 to 39 living or working in an urban community (Accra, Ghana) participated in a quasi-experimental study. For 8 weeks, 32 SMS messages regarding cervical cancer were developed and sent to the personal phones of intervention arm participants (n = 42). Women in the control group (n = 46) received SMS texts with general health and lifestyle advice. Fischer’s exact tests were performed to assess cervical cancer screening uptake and associated reasons for non-uptake between the intervention and control groups (p < 0.05).ResultsAt the baseline, women differed in terms of ethnicity and wealth. After the intervention, participants’ self-reported risk factors for cervical cancer, such as early menarche, usual source of medical treatment, family history of cancer, smoking, and alcohol history, changed. None of the women in the intervention group sought cervical cancer screening after the intervention, but only one (2.2%) of the control arm participants did. Almost all the women (> 95%) agreed that an HPV test was essential and that regular healthcare check-ups could help prevent cervical cancer. Some women believed that avoiding particular foods could help prevent cervical cancer (23.8% intervention vs. 58.7% control, p < 0.001). Time constraints and out-of-pocket expenses were significant barriers to cervical cancer screening. Conclusion: A one-way SMS delivered to urban women did not increase cervical cancer screening attendance. The time spent in screening facilities and the lack of coverage by the National Health Insurance Scheme limited screening uptake. We urge for the establishment of screening centers in all healthcare facilities, as well as the inclusion of cervical cancer screening in healthcare programs through cost-sharing.

Personalized messaging enhances hospital debt collection while prosocial appeals fail: Evidence from a field experiment.

This study aimed to understand how different communication strategies influence patients' behaviour in paying unpaid hospital bills. The research focused on a healthcare system where patients have to pay a significant portion of their medical costs out-of-pocket. The research was conducted in collaboration with a debt collection agency in Latvia. The field experiment involved 9196 individuals with unpaid hospital bills. These individuals received randomly assigned reminders through mobile text messages and e-mails. The study compared the effectiveness of personalized messages, which included the recipient's name, with generic reminders and messages that appealed to social norms or public good contributions. The findings revealed that personalized messages, specifically those that included the recipient's name, significantly improved payment rates compared with generic reminders. Conversely, messages that used social norms or public good appeals did not have a significant impact on payment rates. The study highlights the importance of personalized communication strategies in improving hospital debt collection. Even simple, cost-effective modifications in communication, like adding the recipient's name, can significantly enhance payment compliance. This approach not only keep the financial books of healthcare providers balanced but also suggests that personalized strategies can be extended to other areas of healthcare management. However, while these findings are promising, they indicate that more personalized and nuanced communication strategies are needed to address the broader issue of unpaid hospital bills effectively.

Effectiveness of digital health interventions to increase cardiorespiratory fitness: A systematic review and meta-analysis.

Interventions using commercial digital health tools do favorably affect health outcomes. However, the effect of digital tools on cardiorespiratory fitness, a more novel indicator cardiovascular risk, is unclear. Synthesize the digital health intervention literature and answer the following question: What is the effect of interventions using mobile health apps, wearable activity trackers, and/or text messaging on cardiorespiratory fitness? A systematic review and a meta-analysis (PROSPERO CRD42023423925) were conducted to evaluate the immediate digital health intervention effect on adult cardiorespiratory fitness. In March 2023, a search of databases Embase, MEDLINE, CINHAL, and Cochrane Library was completed. Studies were included if the intervention used a mobile health app, text messaging, and/or activity tracker. Studies were excluded if an objective measure of fitness was not used; the sample included children; the setting was hospital-based; and the digital health technology was only used for data collection or described as virtual reality. Using a random-effects model, two separate meta-analyses were completed: one for single-group studies and one for multi-group studies. Standardized mean difference effect sizes (Cohen's d) were calculated. Study quality was evaluated with the Cochrane Risk of Bias tool and ROBINS-I tool. Fifty-three studies (3657 individuals) with pre-post designs (12 single-group, 41 multi-group) were included. Most studies targeted participants with a specific chronic health condition. Digital health interventions in the single-group studies had a moderate-to-large effect size (d = 0.62, 95% confidence interval (CI) [0.41-0.84], p < 0.001), and multi-group studies had small-to-moderate effect size (d = 0.38, 95% CI 0.21-0.55, p < 0.001). Significant heterogeneity of effects was observed in both the single-group and multi-group studies. Interventions using text messaging, a mobile app, or activity tracker alone or in combination are effective in improving cardiorespiratory fitness in adults, particularly for those with a chronic health condition.

Designing Mobile Phone Text Messages Using the Behavior Change Wheel Framework to Influence Food Literacy in Adults With Type 2 Diabetes in Kenya: Protocol for a Systematic Development Study.

The worldwide prevalence of type 2 diabetes (T2D) has increased in the past decade, and it is projected to increase by 126% by 2045 in Africa. At the same time, mobile phone use has increased in Africa, providing a potential for innovative mobile health interventions to support diabetes care. This study aimed to apply the Behavior Change Wheel (BCW) framework to develop text messages to influence food literacy in adults with T2D in urban Kenya. The 8 steps of the BCW framework guided the development of text messages: (1) Define the problem in behavioral terms; (2) select target behaviors; (3) specify the target behaviors based on who needs to perform the behaviors, what needs to change, and when, where, how often, and with whom; (4) identify what needs to change; (5) identify intervention functions; (6) select policy categories; (7) select behavior change techniques (BCTs); and (8) select the mode of delivery. Recent exploratory studies in Kenya and other low- and middle-income countries provided information that was used to contextualize the intervention. In step 1, the behavioral problem was defined as unhealthy dietary patterns among adults with T2D. In step 2, based on a qualitative study in the target population, the target behavior was selected to be evaluation of reliable sources of information, and selection and preparation of healthy food. In step 3, unhealthy dietary patterns were selected. In step 4, 10 domains of the Theoretical Domains Framework were identified, and in step 5, 5 intervention functions were linked to the domains and unhealthy dietary patterns were specified. In step 6, communication and regulations were identified as policy categories, while in step 7, 9 BCTs were selected from the Behavior Change Technique Taxonomy version 1. In step 8, the most suitable mode of delivery was determined to be mobile text messages. A total of 36 mobile text messages were developed based on the 9 BCTs. This study shows the step-by-step application of the BCW framework to develop mobile text messages to influence food literacy in adults with T2D. RR1-10.2196/48271.

Abstract A004: Quitxt mobile text messaging cessation program for primary care and cancer patients development and implementation process

Abstract Background: Physicians have unparalleled access to smokers. It is estimated that over 70% of smokers visit a physician every year, which provides a powerful opportunity to promote tobacco cessation by asking about smoking behaviors and providing cessation advice and counseling to tobacco users at every visit. In general, smokers consider a physician’s advice to quit an important motivator to make a quit attempt. Every patient is screened for tobacco use; if the patient is a tobacco user, healthcare providers (HCPs) advise them to quit, offer nicotine replacement therapy if needed, and recommend enrollment in the Quitxt program to receive daily messages from the program as well as patient navigator support. Purpose: To conduct a system change to facilitate the integration of Quitxt into the healthcare setting of the Primary Care Center (PCC) and the Mays Cancer Center (MCC) at UT Health San Antonio, to increase accessibility and utilization of a bilingual, evidence-based tobacco cessation service among patients. Methods: We adapted our Quitxt program to the patient population attending the PCC and MCC, integrated it into EPIC, and added it to the Best Practice Advisories Banner. All patients are screened for tobacco use, and if a tobacco-using patient is identified, the Best Practice Advisories banner appears on HCPs’ screen, prompting them to counsel patients to quit and encourage them to enroll in Quitxt. Enrollment cards are available in exam rooms and help providers talk about the program and provide information on how to enroll. The EPIC system also places instructions on how to enroll in Quitxt in the patients’ after-visit summary. Selecting referral to Quitxt activates our Patient Navigators (PNs) follow-up. PNs contact patients monthly and provide support, positive reinforcement, and encouragement. They continue with monthly follow-ups throughout the duration of the program (6 months). Results: To date, 194 patients have been referred to the BestPractice basket. PNs made 829 follow-up phone calls. Of those patients, 104 have enrolled in the program. So far, 96% are English speakers, with a mean age of 47 yrs (SD 11.4); 64% female, 38% Hispanic, the mean number of cigarettes smoked per day was 12, and 60% were ready to make a quit attempt the next day. Preliminary results show cessation rates of 22.1% at day 1; 26.2% at 7 days; 20.4% at 1 month; 31.4% at 4 months and 27.6% at 6 months. Conclusion: Integrating Quitxt into the healthcare setting increases the accessibility and utilization of the Quitxt cessation service among primary care and cancer patients. Quitxt can be easily replicated and represents an affordable approach to reach tobacco-using patients, produce a public health impact, and reduce health service costs and tobacco-related diseases and mortality.

Accessible autonomous transportation and services: voice of the consumer – understanding end-user priorities

Purpose This study aimed to explore the requirements for accessible Autonomous Vehicles (AVs) and AV services from a consumer perspective, focusing on people with disabilities (PwDs) and older adults. Methods Two national surveys were conducted, capturing current transportation trends and AV priorities. Participants (n = 922) with disabilities and older adults were included in the analysis. Results Transportation choices exhibited significant divergence based on the underlying causes of disabilities, showcasing distinct inclinations and impediments within each category. AV services, encompassing family conveyance and package delivery, proved integral, but their specific desirability fluctuated in accordance with the nature of disabilities. Notably, medical appointments emerged as the foremost AV utilisation requirement, particularly pronounced among individuals with hearing impairments. Preferences for orchestrating AV rides and the preferred vehicle types displayed disparities linked to the various disability classifications. The employment of mobile applications, websites, and text messages were preferred mediums for arranging rides. Features such as automated route guidance and collision prevention garnered unanimous precedence among AV attributes. Key priorities, spanning wheelchair accessibility, user profiles, and seamless communication with AVs, were universally emphasised across all participant clusters. The study indicated a moderate comfort level with AV deployment, implying the potential for favourable reception within the population of PwDs and older adults. Conclusion The study highlights the significance of considering diverse needs in accessible AV development of vehicle and infrastructure and policies.

Editable, Persistent, and Emotionally Expressive

Abstract: A 5-day diary study examined how channel affordances are related to channel use and outcomes in romantic conflict. Adults answered five consecutive days of surveys about daily conflict occurrence, channel affordances, channel use, and conflict behavior. The results of a 1–1–1 multilevel mediation analysis showed negative within-indirect effects for the channel affordances of editability and persistence on constructive conflict behavior via mobile text messaging, and a positive within-indirect effect for the channel affordance of bandwidth on constructive conflict behavior via face-to-face communication. The data suggest that channel affordances motivate channel use in romantic conflict and that these channel affordances are indirectly related to constructive conflict behavior.

Adoption of Vaping Cessation Methods by US Adolescent E-Cigarette Users.

A large number of adolescent e-cigarette users intend to quit vaping or have past-year quit attempts. However, it remains unknown which methods they use in their vaping cessation efforts. We analyzed current (past 30-day) e-cigarette users who made ≥1 quit attempt in the past 12 months from the 2021 National Youth Tobacco Survey (NYTS) to examine the prevalence and associations of sociodemographic factors, vaping behaviors, and harm perception with the adoption of different vaping cessation methods. In the 2021 NYTS, there were 1436 current vapers, and 889 (67.9%) had made a past-year quit attempt. Of those, 575 (63.7%) (weighted N = 810 000) reported they did not use any resources (unassisted quitting). Peer support (14.2%), help on the Internet (6.4%), a mobile app or text messaging (5.9%), and parent support (5.8%) were the top 4 cessation methods. Female (versus male) vapers were less likely to solicit parent support (adjusted odds ratio [AOR], 0.2; 95% confidence interval [95% CI], 0.1-0.5), whereas Hispanic (versus White) vapers were more likely to seek friend support (AOR, 2.1; 95% CI, 1.1-3.9) and parent support (AOR, 2.7, 95% CI, 1.2-6.3). Those who perceived vaping to be harmful were less likely to get friend support, but more likely to use a mobile app or text messaging program. Dual users of e-cigarettes and any other tobacco product were more likely to get help from a teacher/coach or a doctor/health care provider and treatment from medical facilities than sole e-cigarette users. There were different correlates with the adoption of vaping cessation methods, highlighting the need for tailored approaches to meet the cessation needs and preferences of the adolescent vaping population.

Mobile Phone Text Messages to Support People to Stop Smoking by Switching to Vaping: Codevelopment, Coproduction, and Initial Testing Study.

SMS text messages are affordable, scalable, and effective smoking cessation interventions. However, there is little research on SMS text message interventions specifically designed to support people who smoke to quit by switching to vaping. Over 3 phases, with vapers and smokers, we codeveloped and coproduced a mobile phone SMS text message program. The coproduction paradigm allowed us to collaborate with researchers and the community to develop a more relevant, acceptable, and equitable SMS text message program. In phase 1, we engaged people who vape via Twitter and received 167 responses to our request to write SMS text messages for people who wish to quit smoking by switching to vaping. We screened, adjusted, refined, and themed the messages, resulting in a set of 95 that were mapped against the Capability, Opportunity, and Motivation-Behavior constructs. In phase 2, we evaluated the 95 messages from phase 1 via a web survey where participants (66/202, 32.7% woman) rated up to 20 messages on 7-point Likert scales on 9 constructs: being understandable, clear, believable, helpful, interesting, inoffensive, positive, and enthusiastic and how happy they would be to receive the messages. In phase 3, we implemented the final set of SMS text messages as part of a larger randomized optimization trial, in which 603 participants (mean age 38.33, SD 12.88 years; n=369, 61.2% woman) received SMS text message support and then rated their usefulness and frequency and provided free-text comments at the 12-week follow-up. For phase 2, means and SDs were calculated for each message across the 9 constructs. Those with means below the neutral anchor of 4 or with unfavorable comments were discussed with vapers and further refined or removed. This resulted in a final set of 78 that were mapped against early, mid-, or late stages of quitting to create an order for the messages. For phase 3, a total of 38.5% (232/603) of the participants provided ratings at the 12-week follow-up. In total, 69.8% (162/232) reported that the SMS text messages had been useful, and a significant association between quit rates and usefulness ratings was found (χ21=9.6; P=.002). A content analysis of free-text comments revealed that the 2 most common positive themes were helpful (13/47, 28%) and encouraging (6/47, 13%) and the 2 most common negative themes were too frequent (9/47, 19%) and annoying (4/47, 9%). In this paper, we describe the initial coproduction and codevelopment of a set of SMS text messages to help smokers stop smoking by transitioning to vaping. We encourage researchers to use, further develop, and evaluate the set of SMS text messages and adapt it to target populations and relevant contexts.

A process evaluation of a health promotion intervention to increase breakfast consumption in children.

This study, part of a community-based nutrition study, aimed to understand the participating experiences of a one-month health promotion intervention in children and parents. The intervention aimed at prompting breakfast consumption amongst children. The specific intervention strategies consisted of mobile text messaging relating to how to cook nutritious and fast breakfast, breakfast-related cartoons provided for children, and group information sessions relating to breakfast consumption for parents. This study, a process evaluation, conducted 30 individual semi-structured interviews. Text messaging may be a feasible delivery modality to promote breakfast consumption in children. The extensive contact intensity or amount of intervention strategies may have an adverse impact on prompting breakfast consumption. Disease- and risk-related educational content has the potential to promote breakfast consumption in children. Text messaging shows promise in increasing breakfast consumption in children, with careful design of contact intensity of educational intervention strategies warranted in the intervention planning process. Content related to the side-effects of breakfast skipping has the potential to promote breakfast consumption in children. However, future research is required to fully understand the quality and effectiveness of these intervention strategies, employing quantitative methodologies.

The Effectiveness of Interactive Text Messaging and Structured Psychosocial Support Groups on Developmental Milestones of Children From Adolescent Pregnancies in Kenya: Quasi-Experimental Study

In sub-Saharan Africa, one-quarter of all pregnancies occur in adolescents. Children born to adolescent mothers have poorer physical and socio-cognitive development. One reason may be inadequate knowledge on childcare and psychosocial support during pregnancy and post partum, since adolescent mothers have less antenatal care attendance and overall interaction with the health care system. Mobile health technology has been used to relay health information to special groups; however, psychosocial support commonly requires physical interaction. We aimed to assess the efficacy of an interactive mobile text messaging platform and support groups in improving adolescent mothers' knowledge and practices as well as infant growth and development. This was a quasi-experimental study, conducted among adolescent mothers with infants younger than 3 months, in Homa Bay County, Kenya. Five of the 8 subcounties in Homa Bay County were purposively selected as study clusters. Four subcounties were assigned as intervention clusters and 1 as a control cluster. Adolescent mothers from 2 intervention subcounties received interactive text messaging only (limited package), whereas those from the other 2 subcounties received text messaging and weekly support groups, moderated by a community health extension worker and a counselor (full package); the control cluster only received the end-line evaluation (posttest-only control). The follow-up period was 9 months. Key outcomes were maternal knowledge on childcare and infant development milestones assessed using the Developmental Milestones Checklist (DMC III). Knowledge and DMC III scores were compared between the intervention and control groups, as well as between the 2 intervention groups. We recruited 791 mother-infant pairs into the intervention groups (full package: n=375; limited package: n=416) at baseline and 220 controls at end line. Attrition from the intervention groups was 15.8% (125/791). Compared with the control group, adolescent mothers receiving the full package had a higher knowledge score on infant care and development (9.02 vs 8.01; P<.001) and higher exclusive breastfeeding rates (238/375, 63.5% vs 112/220, 50.9%; P=.004), and their infants had higher average DMC III scores (53.09 vs 48.59; P=.01). The limited package group also had higher knowledge score than the control group (8.73 vs 8.01; P<.001); this group performed better than the full package group on exclusive breastfeeding (297/416, 71.4% vs 112/220, 50.9%; P<.001) and DMC III scores (58.29 vs 48.59; P<.001) when compared with the control group. We found a marginal difference in knowledge scores between full and limited package groups (9.02 vs 8.73; P=.048) but no difference in DMC III scores between the 2 groups (53.09 vs 58.29; P>.99). An interactive text messaging platform improved adolescent mothers' knowledge on nurturing infant care and the development of their children, even without physical support groups. Such platforms offer a convenient avenue for providing reproductive health information to adolescents. Pan African Clinical Trials Registry PACTR201806003369302; https://tinyurl.com/kkxvzjse.

Exploration of Sindhi Corpus Through Statistical Analysis on the Basis of Reality

Objectives: The Sindhi language is given more importance in Sindh’s educational institutions than other regional languages, and the majority of the population uses it in today’s mobile programs, letters, text messages and other text conversations. Research is needed to analyze the Sindhi corpus, as communication over computer systems and mobile phones is growing significantly. This research study focuses on the Sindhi alphabet and performs different tasks on the corpus. Methods: Data collection was conducted from available resources, and a corpus was created in Sindhi and English. Twenty patterns of letters are used, three dot alignments are used in the letters, and six symbols are used for making letters. After the collection, data was explored and analyzed with different tasks. Findings: The corpus of Sindhi text is being built due to its importance for language, linguistics and other developments in NLP. This research study focuses on statically analyzing the Sindhi-English corpus through reality basis, finding that there are two small words ( ۽ and ۾) and three biggest words ( پاڪستان, انگلینڊ and ڳالھیون ). The letter \' آ\' is used as a single letter in Sindhi alphabets, with the minimum frequently occurring letter being consonant and the maximum frequently being . ئ vowel. Novelty: Text analysis is an important area in data mining and in other research, and this research study focuses on statically analyzing the Sindhi-English corpus through statically on reality basis. The author explores orthography and Sindhi composition of copra, and recommends that the Romanized languages data be used in Sindhi as well. Preprocessing is not easy due to lack of resources, and the character conversion model has generated two languages. Keywords: Sindhi; Language exploration; Corpus; Statistical Analysis; pattern of letters; Text conversation

Effect of receiving mobile text messages on cortisol concentrations in students at the University of the Free State.

Texting has become central to social life, with adverse effects on physiological functioning. Research into the impact of texting on cortisol secretion is limited. Thus study aimed to determine how receiving mobile text messages affected salivary cortisol concentrations and investigate the moderating effects of stress, anxiety and depression on cortisol secretion. Undergraduate physiology students attending physiology lectures at the Faculty of Health Sciences, University of the Free State, 2016. An experimental, crossover, quantitative design was used. Participants were involved over two consecutive days, receiving mobile text messages (intervention) on one day and acting as their own control on the other. Self-reported data on stress, anxiety, depression and subjective experience of the study, and saliva samples were collected. Text frequency and wording (neutral, positive, negative) were varied among participants. Forty-eight students participated in the study. Salivary cortisol concentrations did not differ significantly between the intervention and control days. High anxiety levels were associated with increased cortisol concentrations. No associations with cortisol concentrations were documented in low to moderate anxiety, stress, depression or how participants experienced the intervention. There were no significant differences between text frequency, text emotion and change in cortisol concentrations on the intervention day. Receiving mobile text messages did not elicit a significant cortisol response in participants. Findings added to the body of knowledge about the effect of texting on student learning by measuring salivary cortisol concentrations in a lecture setting, with investigation into the moderating effects of stress, anxiety, depression and participants' subjective experience.

Telessaúde no consumo e comportamento alimentar em adultos: uma revisão rápida de revisões sistemáticas

To synthesize the evidence about the effects of telehealth interventions provided through smart-phone apps and text messages on the behavior of adults regarding healthy food consumption. A rapid systematic review of the literature was performed through searches in nine electronic databases to identify systematic reviews published in English, Portuguese, and Spanish that evaluated telehealth strategies compared to face-to-face interventions to improve dietary intake in the adult population (18 to 59 years old). Searches were performed in November 2020 and updated in April 2022. The included systematic reviews were assessed for methodological quality using the AMSTAR 2 tool. Five systematic reviews were included. Methodological quality was moderate in one review and critically low in four. There was a dearth of studies comparing the use of telehealth strategies with face-to-face interventions for the promotion of healthy eating in adults. The most consistent results refer to an increase in the consumption of fruits and vegetables with the use of an app or text messages, in addition to improvement in the dietary habits of people with diabetes or glucose intolerance with the use of text messages. Positive effects were observed on healthy eating outcomes for most interventions using mobile apps or text messages; however, the findings refer to a few clinical trials with small samples that were analyzed in the systematic reviews covered in the present rapid review, most of which had low methodological quality. Thus, the current knowledge gap warrants the performance of further methodologically robust studies.

CONTRIBUIÇÃO DAS TECNOLOGIAS EDUCACIONAIS DIGITAIS, CONCEBIDAS PARA OS PAIS, NA PROMOÇÃO DO ALEITAMENTO MATERNO: REVISÃO INTEGRATIVA

ABSTRACT Objective: to analyze the contributions of digital educational technologies, designed for fathers, in promoting breastfeeding. Method: a literature review, integrative type, carried out in December 2022, after electronic consultations in the CINAHL, Web of Science, EMBASE, MEDLINE, BDENF, IBECS and LILACS databases, without restriction of language and publication time. Article selection and information extraction were performed by peers independently. Results: sample of seven articles were published between 2017 and 2022 in Australia, Canada and Ethiopia. Digital educational technologies developed for fathers were mobile apps, eHealth resources, and text messaging. These technologies contributed to improve access to information, sharing of experiences, paternal self-efficacy to support breastfeeding, knowledge and attitude about infant feeding, consequently, improving breastfeeding rates. Conclusion: digital educational technologies on breastfeeding, designed for fathers, are poorly studied. However, they are fundamental to improve paternal support in promoting breastfeeding; therefore, more research is needed for the development of other digital educational technologies for this target audience.

Android-Based Short Message Service Filtering using Long Short-Term Memory Classification Model

Short Message Service (SMS) is a technology for sending messages in text format between two mobile phones that support such a facility. Despite the emergence of many mobile text messaging applications, SMS still finds its use in communication among people and broadcasting messages by governments and mobile providers. SMS users often receive messages from parties, particularly for marketing and business purposes, advertisements, or elements of fraud. Many of those messages are irrelevant and fraudulent spam. This research aims at developing android-based applications that enable the filtering of SMS in Bahasa Indonesia. We investigate 1469 SMS text data and classify them into three categories: Normal, Fraudulent, and Advertisement. The classification or filtering method is the long short-term memory (LSTM) model from TensorFlow. The LSTM model is suitable because it has cell states in the architecture that are useful for storing previous information. The feature is applicable for use on sequential data such as SMS texts because every word in the texts constructs a sequential form to complete a sentence. The observation results show that the classification accuracy level is 95%. This model is then integrated into an Android-based mobile application to execute a real-time classification.
