Next phase of CHErIsH study gets underway this month


The CHErIsH (Choosing Healthy Eating for Infant Health) team are delighted to be commencing the next phase of their HRB-funded research on a pioneering intervention aimed at promoting healthy early infant feeding practices in primary care. This next phase seeks to explore the feasibility of the intervention, which will begin at the state-of-the-art Mallow Primary Healthcare Centre (MHPC) – one of the leading centres for primary healthcare in Ireland.

To mark the beginning of this exciting new phase of research, a special launch event was organised by the CHErIsH team at its feasibility site in Mallow. The event, held last week on Tuesday 12th March, featured a ‘launch lunch’, which was attended by healthcare practitioners (GPs and nurses) from the MPHC who will be involved in rolling out the intervention. Launching the event was Professor Patricia Kearney from the School of Public Health at UCC, who is Principal Investigator for the study, and Dr Tony Heffernan, a GP at the MPHC who is leading the study. Also attending the launch were members of the CHErIsH team – Dr Elaine Toomey from NUIG and Dr Caragh Flannery, Dr Kate O’Neill and Susan Calnan from UCC’s School of Public Health.

The feasibility study marks the latest phase of development and implementation of the CHErIsH intervention, which has been designed by a team of researchers from UCC, NUIG and Trinity College Dublin (TCD) – in partnership with practitioners at the MPHC, led by Dr Heffernan, the HSE Nurture Programme, and parents and primary caregivers from the CHErIsH public and patient involvement group. The multi-component intervention seeks to improve early infant (aged 0–2 years) feeding practices, such as breastfeeding and the introduction of solid foods, to improve health outcomes and reduce the risk of overweight and obesity in childhood and later life.

Speaking about this latest phase of the research, CHErIsH team member, Dr Elaine Toomey of NUIG, commented: ‘We are so delighted to be at this exciting stage of the CHErIsH study. It’s been a real honour to have worked so closely with the excellent team in Mallow and the HSE Nurture programme, to develop something that we think has the potential to make a valuable contribution to child health. We are really looking forward to learning as much as we can from this testing to inform the next steps of research’.  

Results from the study will help to determine the feasibility of the intervention, which will informing further testing to determine the effectiveness of the intervention in other primary care sites. The CHErIsH team look forward to updating readers on more news about this pioneering intervention over the coming months.

‘Exploring intervention fidelity in trials of interventions to change infant feeding behaviours – are we testing what we think we’re testing?’

CHErIsH researcher Dr Elaine Toomey has recently written a blog post for the SPHeRE (Structured Population and Health-Services Research Education) programme on one of the CHErIsH study research papers.

Find the original blog here, or read on below:


The first two years of life represent an important stage in a child’s development. In particular, how and what a child is fed during this time has an important influence on their subsequent development. For example, infant feeding behaviours such as the early or inappropriate introduction of solid foods into a child’s diet have been associated with the later development of childhood obesity [1, 2]. Childhood obesity is an urgent global concern, with serious health, economic and social implications both for the individual and the wider health system. Therefore infant feeding behaviours represent a potential target for the prevention of childhood obesity and a worthwhile focus for behaviour change intervention research.

To date, studies have found that the effectiveness of infant feeding interventions to prevent childhood obesity to be somewhat variable and inconsistent [3, 4]. However, little is known about the actual implementation of the interventions within these trials, and the ‘fidelity’ with which they were put into practice. Intervention fidelity refers to the extent to which an intervention is actually implemented as intended by the researchers who designed it [5]. For example, are all aspects of the intervention delivered by the providers as planned? Do participants actually attend or engage with the intervention, do they receive or use intervention materials or resources as intended? Intervention fidelity is an important methodological aspect of behavioural studies, as without knowledge of intervention fidelity we are only really assuming that the intended intervention is being tested.

In a recent systematic review [6], we explored the use and reporting of different strategies to enhance and assess intervention fidelity within trials of infant feeding interventions delivered by healthcare professionals to prevent childhood obesity. We also explored the associations between fidelity score and study quality, intervention effectiveness and publication year. Using a systematic search strategy we identified 10 trials represented in 16 papers. Across these studies, the average use and/or reporting of strategies to enhance (e.g. training manuals/protocols) and/or assess intervention fidelity (e.g. delivery checklists) was moderate (54%), ranging from 28.9% to 76.7%. No patterns were observed between levels of fidelity reporting/use and study quality, effectiveness or publication year. Interestingly, although six studies reported using a method to assess fidelity of intervention delivery, only 2 studies explicitly reported the results of this fidelity assessment.

The moderate use/reporting of fidelity strategies within trials of infant feeding interventions identified in our review suggest that previous findings of inconsistent effectiveness may not fully reflect the intended interventions. As a result, our study identified a number of recommendations that could improve the methodological quality of future trials of infant feeding interventions, to ensure that these trials are a more accurate test of the intervention in question. These include 1) ensuring adequate focus on how intervention providers are trained and the knowledge and skills needed to deliver the intervention as intended, 2) ensuring adequate focus on the fidelity of treatment within comparator or control groups and 3) ensuring better reporting across all aspects of fidelity, in particular the results of fidelity assessments. In doing so, improved intervention fidelity will facilitate better interpretation and understanding of the findings of such trials, and provide more information to support the translation of successful interventions into policy and practice.
