Implementing the Bloom Trial: Community health nurses’ perceptions of potential barriers

Background

The overall aim of the Bloom Trial is to develop and test a program promoting healthy weight development during infancy within the community health nurse setting in Denmark. Many interventions are poorly implemented, and to ensure adequate implementation support, previous studies have suggested to assess barriers and organizational readiness before intervention start. The aim of the present study is to assess barriers for implementing and sustaining the Bloom Trial among program adopters and implementers.

Methods

Telephone interviews with managing health nurses (adopters) and health nurses (implementors) from twenty Danish municipalities were carried out (n = 22) in 2017. Moreover, two workshops with health nurses, and continuously meetings with implementation science experts were conducted in 2021-2022.

Results

Barriers were identified on different levels. Organizational barriers within the work of health nurses included lack of time, economic resources, project fatigue, and political priority. Furthermore, health nurses lacked relevant tools to guide parents about promoting healthy weight development. Interpersonal barriers between health nurses and parents were identified as the difficulties of having conversations about healthy weight development, especially if the parents or health nurses were overweight themselves. Cultural differences including language barriers and different perceptions of for example healthy food choices were also found.

Conclusions

The findings are central for ensuring that the Bloom Trial is relevant and applicable to the setting of health nurses in Danish municipalities. This is crucial for ensuring successful adoption, implementation, and prolonged sustainability.

Key messages

• The study pinpoints key barriers (e.g. lack of time, project fatigue and cultural factors) of implementing an intervention promoting healthy weight in the community health nurse setting in Denmark.

• Involving community health nurses’ perceptions aim at increasing the chances of producing a relevant and successful implementation strategy.

Using Intervention Mapping to develop an intervention to promote healthy child weight development

Background

Clear documentation of the understanding of the problem, development process, and content of interventions is essential to understand why interventions succeed or fail. Transparent reporting will enable future researchers to build on previous evidence and replicate or adapt interventions for new contexts. This paper describes the theory- and evidence-based systematic development of the Bloom Trial - a home-based intervention to promote healthy weight development among infants and children in Denmark.

Methods

Development of the intervention is guided by the six-step planning tool the Intervention Mapping protocol. Step 1: Needs assessment including identification of risk factors in infancy and existing interventions, interviews with parents, and an organizational capacity assessment. Step 2: Development of program theory and matrices. Step 3: Selection of theoretical methods and practical applications for modifying personal and environmental determinants. Step 4: Development of intervention tools. Step 5: Planning of program adoption, implementation, and sustainability. Step 6: Generation of an evaluation plan.

Results

The Bloom intervention is universal but with a strong focus on families with low socio-economic position and non-Danish ethnic background. It is aimed at first-time parents and addresses early risk factors for child overweight such as parental skills and healthy habits related to food and meals, movement, screen time and sleep, and introduce a new theme: sense of security in the family. It will be integrated in existing services delivered by community health nurses supplemented with extra elements such as telephone consultations, family groups and a video library.

Conclusions

The transparency of the developmental process and theoretical, empirical, and contextual foundation of the Bloom Trial may enable future studies to build on our findings and accumulate knowledge to promote healthy weight development among infants and children.

Parents’ perceptions of barriers & facilitators for adhering to advice from community health nurses

Background

Childhood obesity is a global health problem and infancy is an important window of opportunity for promoting healthy weight development. In Denmark, community health nurses cover most families with a new-born child leaving a huge potential for promoting healthy weight development. This study examines parents’ perceptions of barriers and facilitators for adhering to advice from the health nurse regarding healthy weight development of their child.

Methods

Sixteen interviews with parents (children aged 0- 2 years) living in Denmark were conducted. Parents were strategically sampled representing variations across child age, family socioeconomic position, ethnicity, and geography. All interviews were based on a semi-structured interview guide, recorded, and transcribed verbatim and analysed using a thematic analysis.

Findings

Parents generally experience visits from their health nurse positively. Health nurses are emphasized as a confident and trustful relation and the key informant about children's’ health. Variations in how parents adhere to advice favouring healthy weight development of their child were found. Generally, parents adopted a positive attitude towards the health nurse, also when she addressed behaviour or practice of the parents, but parents expressed the importance of doing so in a non-stigmatising or finger pointing manner. The degree to which parents follow the advice from their health nurse depend on cultural background, advice from family and friends, and use of online information.

Conclusions

Parents generally have a confident and trustful relation to the health nurse, and she constitutes the key informant on child health. This leaves a potential for the structure of Danish health nurses for future interventions promoting healthy weight development. Adaptation of the future intervention program to the needs of parents will increase the chances of developing a relevant, successful, and sustainable intervention.

Key messages

• Health nurses are emphasized as a trustful relation and the key informant about children’s’ health, but parents expressed the importance of addressing behaviours in a non-stigmatising manner.

• Adapting information gained from parents in development of the trial will increase the chances of a relevant, successful, and sustainable intervention promoting healthy child weight development.
