Telephone and Web-Based Delivery of Healthy Eating and Active Living Interventions for Parents of Children Aged 2 to 6 Years: Mixed Methods Process Evaluation of the Time for Healthy Habits Translation Trial. J Med Internet Res 2022; 24:e35771. [PMID: 35616994 PMCID: PMC9185338 DOI: 10.2196/35771] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/16/2021] [Revised: 02/16/2022] [Accepted: 03/21/2022] [Indexed: 11/24/2022] Open
Abstract
Background Few translational trials have provided detailed reports of process evaluation results. Objective This study reported on findings from a mixed methods process evaluation of a large translational trial comparing 2 remotely delivered healthy eating and active living interventions with an active control, targeting parents of young children. Methods Mixed methods process evaluation data were collected as part of a 3-arm, partially randomized preference trial targeting parents of children aged 2 to 6 years from New South Wales, Australia. Recruitment strategies were assessed through the participant baseline questionnaire and a questionnaire completed by the health promotion staff involved in recruitment. Data on participants’ intervention preferences were collected at baseline and after the intervention. Intervention acceptability and demographic data were collected via a postintervention questionnaire (approximately 3 months after baseline), which was supplemented by qualitative participant interviews. Implementation data on intervention fidelity and withdrawal were also recorded. Differences in intervention acceptability, fidelity, and withdrawal rates between telephone and web-based interventions and between randomized and nonrandomized participants were analyzed. The significance level was set at P<.05 for all tests. The interview content was analyzed, key themes were drawn from participant responses, and findings were described narratively. Results Data were collected from 458 participants in the baseline survey and 144 (31.4%) participants in the 3-month postintervention survey. A total of 30 participants completed the qualitative interviews. A total of 6 health promotion staff members participated in the survey on recruitment strategies. Most participants were recruited from Early Childhood Education and Care services. There was a broad reach of the study; however, better take-up rates were observed in regional and rural areas compared with metropolitan areas. Parents with a university education were overrepresented. Most participants preferred the web-based medium of delivery at baseline. There was high acceptability of the web-based and telephone interventions. Participants found the healthy eating content to be the most useful component of the modules (web-based) and calls (telephone). They regarded text (web-based) or verbal (telephone) information as the most useful component. A high proportion of participants completed the telephone intervention compared with the web-based intervention; however, more participants actively withdrew from the telephone intervention. Conclusions This is one of the first studies to comprehensively report on process evaluation data from a translation trial, which demonstrated high acceptability of all interventions but a strong participant preference for the web-based intervention. This detailed process evaluation is critical to inform further implementation and be considered alongside the effectiveness outcomes.

Effects of telephone support or short message service on body mass index, eating and screen time behaviours of children age 2 years: A 3-arm randomized controlled trial. Pediatr Obes 2022; 17:e12875. [PMID: 34821063 PMCID: PMC9285384 DOI: 10.1111/ijpo.12875] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/21/2021] [Revised: 11/01/2021] [Accepted: 11/08/2021] [Indexed: 11/28/2022]
Abstract
BACKGROUND Few randomized controlled trial (RCT) interventions targeted children's early risk behaviours using telephone or short message service (SMS) support. OBJECTIVE To evaluate the effectiveness of telephone or SMS early intervention focusing on mothers' behaviours starting from late pregnancy to improve BMI, and eating and screen time behaviours of children aged 2 years in comparison with the control group. METHODS A 3-arm RCT was conducted in Australia, 2017-2019. Two arms involved the interventions using nurse-led telephone or SMS support, delivered in nine stages from late pregnancy to age 2 years. The third arm was control. The primary outcome was children's objectively measured BMI and BMI z-score at 2 years. Secondary outcomes included child eating and screen time behaviours as reported by parents at 2 years. RESULTS At 2 years, 797 mother-child dyads (69%) completed the telephone survey with 666 (58%) completing weight and height measurements. The study found no statistically significant difference in BMI between the groups. The mean BMI for telephone support was 16.93 (95% CI: 16.73 to 17.13), for SMS 16.92 (95% CI: 16.73 to 17.11) or for control 16.95 (95% CI: 16.73 to 17.16) with a difference of -0.02 (95% CI: -0.31 to 0.27, p = 0.907) in telephone versus control, and a difference of -0.03 (95% CI: -0.30 to 0.24, p = 0.816) in SMS versus control. Telephone support was associated with higher odds of no bottle at bedtime (adjusted odds ratio [AOR]: 2.99; 95% CI: 2.01 to 4.47), family meals (AOR: 2.05; 95% CI: 1.26 to 3.33), drinking from a cup (AOR: 1.89; 95% CI: 1.24 to 2.88), less screen time (<1 h/day) (AOR: 1.56; 95% CI: 1.10 to 2.23) and not eating dinner in front of the TV (AOR: 1.50; 95% CI: 1.09 to 2.06). SMS support was also associated with higher odds of no bottle at bedtime (AOR 2.30, 95% CI: 1.58 to 3.33) than the control. CONCLUSION The telephone or SMS support intervention had no significant effects on BMI, but was effective in increasing no bottle use at bedtime. Telephone support showed more effects than SMS on reducing screen time and eating behaviours.

Participants' Engagement With Telephone Support Interventions to Promote Healthy Feeding Practices and Obesity-Protective Behaviours for Infant Obesity Prevention. Front Endocrinol (Lausanne) 2022; 13:868944. [PMID: 35586630 PMCID: PMC9108251 DOI: 10.3389/fendo.2022.868944] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/03/2022] [Accepted: 03/21/2022] [Indexed: 11/13/2022] Open
Abstract
BACKGROUND Participant engagement with program interventions is vital to support intended behaviour changes and outcomes. The aim of this research was to investigate participant engagement with the Communicating Healthy Beginnings Advice by Telephone (CHAT) program, an early childhood obesity prevention program that included interventions for promoting healthy infant feeding practices and obesity-protective behaviours via telephone, and whether engagement with the telephone support program varied by participants' sociodemographic characteristics. METHODS This study used de-identified CHAT program data of participants who received the interventions via telephone. Data analysed included 1) participant engagement in telephone support from late pregnancy to 12 months of child's age, 2) demographic characteristics collected at late pregnancy and 3) intervention providers' observations and notes (qualitative data) for 10 participants from each engagement group (low, medium, high) to explore issues discussed during telephone support. RESULTS Call completion rate by participants was above sixty percent for all six stages of the telephone support program with more than half of the participants (57%) demonstrating high level of engagement. We found that participants' country of birth, employment status and annual household income were predictors of engagement with the telephone support provided in the CHAT program. The odds of participants' engagement with the telephone support program were 1.68 times higher for Australian born (95% CI 1.07 - 2.62), 1.63 times higher for participants who were employed (95% CI 1.01 - 2.66) and 1.63 times higher for participants with annual household income ≥AUD$80,000 (95% CI 1.02 - 2.60). CONCLUSIONS Participant engagement with the program interventions was good. Participants' engagement with the telephone support program was significantly associated with certain socio-demographic characteristics. Australian born participants, and participants associated with higher household income and employment engaged significantly more with the telephone support provided in the CHAT program. Additionally, the program engaged more participants older than 30 years of age and those who spoke English at home. The program provided unintended personal benefits to some participants with high engagement level due to their various psychosocial needs such as domestic violence, mental health and sleep related issues. Although not an intended benefit of the intervention, psychosocial needs of participants were met which was a likely factor for mothers' engagement with the program. This is an important factor that needs to be considered while implementing future programs or scale up of this program.

Abstract
ISSUE ADDRESSED One in four Australian children aged between the ages of two and four are affected by overweight. In New South Wales, the Communicating Healthy Beginnings Advice by Telephone (CHAT) trial delivered an intervention to pregnant women and women with infants via telephone calls and text messages. The focus of the intervention was on infant feeding and establishing healthy habits for infants by building the capacity of mothers. This study investigates trial collaborators' perspectives concerning the implementation of this intervention, to obtain insights that will support future translation and scale-up. METHODS This research was undertaken during the intervention phase of the trial. Twenty trial collaborators involved in the planning, implementation or delivery of the CHAT trial were invited to participate. Qualitative interviews were conducted with collaborators using open-ended questions based on Steckler and Linnan's process evaluation framework and the Consolidated Framework for Implementation Research. Inductive thematic analysis was employed to identify themes from the interview data. RESULTS Fourteen trial collaborators were interviewed. Collaborators included child and family health nurses (intervention providers), nurse managers with extensive child and family health nursing experience, a paediatrician, dietitians, health promotion experts, health service managers, health and nursing executives, program personnel (project coordinator, research fellow and evaluation officer) and university researchers. Following coding of qualitative data, themes were realised from the data as a result of active co-production on the part of the researcher. Five themes were identified: (a) context (organisational support, engagement and partnerships, communication and project leadership); (b) program receipt, benefit and reach; (c) program delivery (intervention providers' experience and skills, mode of intervention delivery, referral to other services, support and training for intervention providers); (d) implementation (program delivered as planned); (e) opportunities for scale-up. Collaborators perceived that the program was implemented and delivered as planned. This specific research addresses the success of the process of implementing and delivering interventions for infant feeding and establishing healthy habits for children by building the capacity of mothers. Collaborators attributed successful program implementation to contextual factors: strong support by the host organisation; good project leadership; clear communication; collaborative internal and external partnerships; intervention provision by experienced nurses. Remote delivery was convenient to program participants and participants were able to resolve other personal concerns in addition to direct immediate benefits. Because of their capacity to influence policy decisions, the absence of policymakers at project meetings was a shortcoming. Collaborative partnerships with health and research partners, understanding of contextual issues and consumer involvement could lead to program expansion. The program has the potential to be scaled up through integration with existing services and gradual expansion into other health districts prior to state-wide rollout. CONCLUSIONS The CHAT trial delivered the Healthy Beginnings intervention which resulted in improvements in infant feeding, active play and sedentary behaviours. This evaluation demonstrated that the involvement of key stakeholders from early planning stages through to implementation of the program and the partnerships that evolved contributed to the successful implementation of the program. An unintended benefit to participants from this program was the social support that was provided. Intervention delivery via telephone and text messages enabled easy access to the program. Most importantly, the program has the potential to be scaled up through integration into existing services and gradual expansion prior to state-wide rollout. SO WHAT?: Strong internal and external partnerships, effective communication systems and integration with existing services create the context for potential translation and scaling up of the program to other health promotion settings.

Abstract
BACKGROUND Early obesity prevention research interventions in Australia generally expect participants to be able to communicate in English, but do not account for other languages. This study aimed to investigate engagement, satisfaction, retention and behavioural outcomes of linguistically diverse participants from a mainstream early childhood obesity prevention trial. METHODS Healthy Beginnings is a nurse-led intervention based in Sydney, supporting families with optimal infant feeding and active play via telephone. This secondary analysis assessed participant engagement in the nurse telephone calls (call completions), satisfaction and behavioural outcomes (6- and 12-month survey data) and retention (survey completions), in the first year of life according to participants' language spoken at home (English or other language). RESULTS Of 1155 mothers, 533 (46%) spoke a language other than English at home. Significantly fewer mothers speaking a language other than English completed the 6-month survey (79%) compared to those speaking English (84%), yet mothers speaking a language other than English who completed the program were more satisfied with the program overall. Significantly fewer mothers speaking a language other than English completed the final four nurse calls (of six) (56%-65%) compared to those speaking English (70%-80%). Adjusted odds ratios showed selected behavioural outcomes were significantly more positive for participants speaking English at home. CONCLUSIONS Healthy Beginnings trial participants who spoke a language other than English at home had less favourable engagement, retention and behavioural outcomes compared to those who spoke English. So what? Early obesity prevention interventions should consider cultural adaptations to improve engagement and effectiveness among culturally and linguistically diverse families.

Abstract
Obesity prevention interventions with behavioral or lifestyle-related components delivered via web-based or telephone technologies have been reported as comparatively low cost as compared with other intervention delivery modes, yet to date, no synthesized evidence of cost-effectiveness has been published. This study aimed to conduct a systematic review of economic evaluations of obesity prevention interventions with a telehealth or eHealth intervention component. A systematic search of six academic databases was conducted through October 2020. Studies were included if they reported full economic evaluations of interventions aimed at preventing overweight or obesity, or interventions aimed at improving obesity-related behaviors, with at least one intervention component delivered by telephone (telehealth) or web-based technology (eHealth). Findings were reported narratively, based on the Consolidated Health Economic Evaluation Reporting Standards. Twenty-seven economic evaluations were included from 20 studies meeting the inclusion criteria. Sixteen of the included interventions had a telehealth component, whereas 11 had an eHealth component. Seventeen interventions were evaluated using cost-utility analysis, five with cost-effectiveness analysis, and five undertook both cost-effectiveness and cost-utility analyses. Only eight cost-utility analyses reported that the intervention was cost-effective. Comparison of results from cost-effectiveness analyses was limited by heterogeneity in methods and outcome units reported. The evidence supporting the cost-effectiveness of interventions with a telehealth or eHealth delivery component is currently inconclusive. Although obesity prevention telehealth and eHealth interventions are gaining popularity, more evidence is required on their effectiveness and cost-effectiveness.

Abstract
INTRODUCTION Healthy Beginnings is an established nurse-led early childhood obesity prevention program that promotes healthy infant feeding practices and active play in the early years of life. To improve engagement with culturally and linguistically diverse populations, the Healthy Beginnings program delivered by telephone was culturally adapted and implemented with Arabic- and Chinese-speaking mothers in Sydney, Australia. The cultural adaptation process has been published separately. In this article, we aimed to evaluate the feasibility of the culturally adapted program. METHODS In 2018-2019, the culturally adapted Healthy Beginnings program was implemented with Arabic- and Chinese-speaking women recruited from antenatal clinics in Sydney. At four staged timepoints (from third trimester until 6 months of age), mothers were sent culturally adapted health promotion booklets and text messages and offered four support calls from bi-cultural child and family health nurses in Arabic and Chinese. A mixed methods evaluation included a) baseline and 6-month telephone surveys, followed by b) semi-structured follow-up interviews with a subset of participating mothers and program delivery staff. Main outcomes of this feasibility study were reach (recruitment and retention), intervention dose delivered (number of nurse support calls completed) and acceptability (appropriateness based on cognitive and emotional responses). RESULTS At recruitment, 176 mothers were eligible and consented to participate. Of 163 mothers who completed the baseline survey, 95% completed the program (n = 8 withdrew) and 83% completed the 6-month survey (n = 70 Arabic- and n = 65 Chinese-speaking mothers). Most mothers (n = 127, 78%) completed at least one nurse support call. The qualitative analysis of follow-up interviews with 42 mothers (22 Arabic- and 20 Chinese-speaking mothers) and 10 program delivery staff highlighted the perceived value of the program and the positive role of bi-cultural nurses and in-language resources. Mothers who completed more nurse support calls generally expressed greater acceptability. CONCLUSIONS The culturally adapted Healthy Beginnings program was feasible to deliver and acceptable to Arabic- and Chinese-speaking mothers. Our results highlight the importance of in-language resources and individualised bi-cultural nurse support by telephone for supporting culturally and linguistically diverse migrant families with infant feeding and active play. These findings support the potential for program refinements and progression to an effectiveness trial.

Abstract
Childhood overweight and obesity is a worldwide public health issue. Our objective was to describe planned, ongoing and completed randomized controlled trials (RCTs) designed for the prevention of obesity in early childhood. Two databases (World Health Organization International Clinical Trials Registry Platform, ClinicalTrials.gov) were searched to identify RCTs with the primary aim of preventing childhood obesity and at least one outcome related to child weight. Interventions needed to start in the first two years of childhood or earlier, continue for at least 6 months postnatally, include a component related to lifestyle or behaviours, and have a follow up time of at least 2 years. We identified 29 unique RCTs, implemented since 2008, with most being undertaken in high income countries. Interventions ranged from advice on diet, activity, sleep, emotion regulation, and parenting education through to individual home visits, clinic-based consultations, or group education sessions. Eleven trials published data on child weight-related outcomes to date, though most were not sufficiently powered to detect significant effects. Many trials detected improvements in practices such as breastfeeding, screen time, and physical activity in the intervention groups compared to the control groups. Further follow-up of ongoing trials is needed to assess longer-term effects.

The process of culturally adapting the Healthy Beginnings early obesity prevention program for Arabic and Chinese mothers in Australia. BMC Public Health 2021; 21:284.

Abstract
Background Behavioural interventions for the early prevention of childhood obesity mostly focus on English-speaking populations in high-income countries. Cultural adaptation is an emerging strategy for implementing evidence-based interventions among different populations and regions. This paper describes the initial process of culturally adapting Healthy Beginnings, an evidence-based early childhood obesity prevention program, for Arabic and Chinese speaking migrant mothers and infants in Sydney, Australia. Methods The cultural adaptation process followed the Stages of Cultural Adaptation theoretical model and is reported using the Framework for Reporting Adaptations and Modifications-Enhanced. We first established the adaptation rationale, then considered program underpinnings and the core components for effectiveness. To inform adaptations, we reviewed the scientific literature and engaged stakeholders. Consultations included focus groups with 24 Arabic and 22 Chinese speaking migrant mothers and interviews with 20 health professionals. With input from project partners, bi-cultural staff and community organisations, findings informed cultural adaptations to the content and delivery features of the Healthy Beginnings program. Results Program structure and delivery mode were retained to preserve fidelity (i.e. staged nurse calls with key program messages addressing modifiable obesity-related behaviours: infant feeding, active play, sedentary behaviours and sleep). Qualitative analysis of focus group and interview data resulted in descriptive themes concerning cultural practices and beliefs related to infant obesity-related behaviours and perceptions of child weight among Arabic and Chinese speaking mothers. Based on the literature and local study findings, cultural adaptations were made to recruitment approaches, staffing (bi-cultural nurses and project staff) and program content (modified call scripts and culturally adapted written health promotion materials). Conclusions This cultural adaptation of Healthy Beginnings followed an established process model and resulted in a program with enhanced relevance and accessibility among Arabic and Chinese speaking migrant mothers. This work will inform the future cultural adaptation stages: testing, refining, and trialling the culturally adapted Healthy Beginnings program to assess acceptability, feasibility and effectiveness.

Process evaluations of early childhood obesity prevention interventions delivered via telephone or text messages: a systematic review. Int J Behav Nutr Phys Act 2021; 18:10. [PMID: 33422066 PMCID: PMC7796572 DOI: 10.1186/s12966-020-01074-8] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2020] [Accepted: 12/14/2020] [Indexed: 02/06/2023] Open
Abstract
Background Increasingly, public health interventions are delivered via telephone and/or text messages. Recent systematic reviews of early childhood obesity prevention interventions have not adequately reported on the way interventions are delivered and the experiences/perceptions of stakeholders. We aimed to summarise the literature in early childhood obesity prevention interventions delivered via telephone or text messages for evidence of application of process evaluation primarily to evaluate stakeholders’ acceptability of interventions. Methods A systematic search of major electronic databases was carried out using the Population, Intervention, Comparison, Outcomes framework. Studies were included if interventions were delivered via telephone/text messages; aimed at changing caregivers’ behaviours to prevent early childhood obesity; with one or more outcomes related to early obesity risk factors such as breastfeeding, solid feeding, tummy time, sleep and settling, physical activity and screen time; published from inception to May 2020. All eligible studies were independently assessed by two reviewers using the Cochrane Collaboration tool for assessing risk of bias. Qualitative studies were assessed using the Consolidated Criteria for Reporting Qualitative Research and Standards for Reporting Qualitative Research tools. Results Twenty-four studies were eligible, and the overall risk of bias was low. Eight studies (33%) had evidence of process evaluation that examined participants’ perceptions of interventions. Participants appreciated the convenience of receiving interventions via telephone or text messages. 63% of all studies in this review showed improvement in one or more behaviours related to childhood obesity prevention. Participants were likely to modify behaviours if they received information from a credible source such as from health professionals. Conclusion There is limited reporting of stakeholders’ experiences in early obesity prevention studies delivered by telephone or text messages. Only one-third of studies examined participants’ acceptability and the potential for delivery of childhood obesity prevention interventions conveniently using this mode of delivery. Interventions delivered remotely via telephone or text messages have the potential to reach equal or a greater number of participants than those delivered via face-to-face methods. Future research should build in process evaluation alongside effectiveness measurements to provide important insight into intervention reach, acceptability and to inform scale up.
