Our evidence base
HENRY has the strongest evidence base of any national healthy start initiative in the UK with ‘statistically significant’ sustained changes in parenting, diet, physical activity, emotional wellbeing and lifestyle habits.
Following a rigorous process, the Early Intervention Foundation awarded HENRY the maximum possible effectiveness score for interventions without a published Randomised Controlled Trial (RCT).
Rooted in best available research about risk and protective factors for future health
HENRY is an innovative intervention to promote a healthy start in life and lay the foundations for a healthier future by focusing on babies and children aged 0-5 and their families. It was originally developed in response to an identified gap: for a practical intervention to deliver the evidence-based messages contained in Professor Mary Rudolf’s report commissioned by the Department of Health in 2009, Tackling obesity through the healthy child programme: a framework for action. Now, it is applicable much more widely than obesity prevention.
The HENRY intervention addresses the research evidence on risk and protective factors for child obesity and a healthy start more widely - including oral health, breastfeeding and school readiness. It adopts a holistic approach which brings together these key factors, focusing on:
- family lifestyle habits
- emotional wellbeing
This approach is multi-layered and brings together:
- workforce development: equipping health and early years practitioners with the skills, knowledge and confidence to tackle a range of sensitive lifestyle issues and enable them to make the most of every contact with families
- preventive parent programmes and subject-specific workshops
- targeted treatment programmes for families with children who need specialist support
- parent-led peer support schemes to promote a healthy family lifestyle with local communities
Evaluation of the HENRY programme
HENRY has the strongest evidence base currently available for any UK early intervention programme designed to support a healthy start. Professor Mary Rudolf, paediatrician and expert in child growth, is HENRY’s academic adviser and supports the programme’s ongoing development and evaluation. Long term academic partnerships have enabled robust evaluation and contributed to research knowledge and understanding about successful interventions to tackle lifestyle issues in children. The HENRY programme is now proceeding to Randomised Control Trial (RCT).
Peer-reviewed and published evidence using validated measures shows that HENRY works.
Specifically, it has demonstrated that:
- Families participating in the HENRY programme make statistically significant improvements to family lifestyle and parenting efficacy which are sustained over time (details below)
- Brief HENRY training has a sustained impact on practitioners’ professional and personal lives
- HENRY training leads to improvement in nutritional policy and practice at Children’s Centres
Family lifestyle changes
- increased frequency of happiness and decreased frequency of stress
- increased parenting self-efficacy
- increased consumption of fruit and vegetables and water
- decreased consumption of energy-dense food and sugar-sweetened drinks
- decreased frequency of TV meals and increased frequency of family meal times
- increased family physical activity
Replication and system readiness
HENRY is currently commissioned in around 35 local authority areas. HENRY has embedded evaluation and delivery processes in place to ensure programme fidelity and outcomes:
- Intervention specificity: target group, outcomes, components and theoretical underpinning are clearly articulated and a detailed manual supports programme delivery
- Quality assurance: practitioners receive initial training and ongoing supervision to equip them with the skills, knowledge and confidence to deliver the programme and are authorised against specified criteria
- Evaluation of impact: participating parents are asked to complete baseline, completion and follow-up questionnaires which incorporate validated instruments used successfully in previous HENRY evaluations and adapted for community settings.
- 5-item Parenting Self-Agency Measure
- Hammond’s Food Frequency Questionnaire
- Golan’s Family Eating and Activity Habits questionnaire
Incorporates evidence-based practices
HENRY was developed by Professor Mary Rudolf and Candida Hunt, parenting educator and behaviour change specialist. The HENRY approach to supporting families to change entrenched lifestyle and eating habits incorporates proven models of behaviour change:
- Family Partnership Model
Emphasises the importance of the parent–practitioner relationship and integrating parents’ expertise with that of helpers. It is associated with positive outcomes including improvements in family relationships, and children’s development, behaviour and emotional functioning
- Strengths-based, solution-focused support
Based on highlighting strengths and identifying solutions, and widely used in clinical settings (in the form of solution-focused brief therapy), with positive treatment effects
- Motivational interviewing
Person-centred collaborative form of guiding to elicit and strengthen motivation for change
HENRY was awarded the highest effectiveness score possible without an RCT
