Model description

Healthy Families: Right from the Start (known as HENRY) is for all parents of a child between 0 and 5 years old. HENRY provides parents with strategies for implementing and maintaining a healthy diet and increasing family physical activity.

HENRY is delivered by family support workers to groups of eight to 10 parents over eight weekly, 2.5-hour sessions.

During these sessions, parents are guided as the primary agents of change for their children, covering key topics such as healthy routines, balanced diets, screen time, emotional wellbeing, portion sizes, and positive mealtime strategies. HENRY employs motivational interviewing and a strengths-based, solution-focused approach, encouraging active participation through group discussions, role-play, and small group activities.

Parents also receive a HENRY Healthy Families workbook, which offers practical activities and accessible information to help them implement lasting, positive changes at home. The intervention fosters learning by building on parents’ existing skills and experiences while providing support to create healthier family lifestyles.

Age of child

0 to 5 years old

Target population

Parents with children aged 0 to 5 years old.

Why?

Science-based assumption

Excess weight in early childhood increases the risk of obesity and diabetes in later childhood and adulthood 

Over one-quarter of all children in the UK are currently obese.

Science-based assumption

Family diet and low levels of physical activity increase the risk of childhood obesity and poor physical health.

Who?

Science-based assumption

All families can benefit from increased information about a healthy lifestyle. 

How?

Intervention

Parents learn strategies for healthy eating and physical exercise that can be incorporated into their daily routines. 

What?

Short-term

Parents and children have a better understanding of healthy dietary and activity patterns 

Parents and children incorporate healthy diet and physical activities into their daily and weekly family routines. 

Medium-term

Children reach and maintain a healthy BMI for their height and age. 

Long-term

Healthy eating habits in adulthood 

Increased physical activity in adulthood 

Reduced obesity risk in childhood and adulthood. 

Who is eligible?

Eligible participants were parents of infants and preschool children who were attending Children’s Centres and interested in participating in an intervention to improve their family’s lifestyle.

How is it delivered?

HENRY is delivered by family support workers to groups of eight to 10 parents over eight weekly, 2.5-hour sessions.

What happens during the intervention?

The topics covered in the eight sessions include: family routines and parenting skills that support a healthy family lifestyle; healthy balanced diet for young children and the whole family; being active; screen time; emotional wellbeing; labels and healthy sugar swaps; portion sizes for under-5s; and happier, calmer mealtimes.

  • The intervention is based on evidence that parenting efficacy and wellbeing underpin a healthy start in life. It therefore integrates support for parenting skills alongside information about nutrition and activity. For example, it helps develop non-food strategies to encourage cooperative behaviour rather than using sweets as a reward or comfort
  • Session topics are introduced and facilitated to encourage joint exploration and build on what parents already know and are doing, rather than simply providing information. Learning activities include working in pairs and small groups to share ideas, whole-group discussion, demonstrations, and role-play
  • Participating families receive the HENRY Healthy Families workbook which provides a structured framework of activities and simple, accessible background information for each session.

Who can deliver it?

HENRY is delivered by two family support workers.

What are the training requirements?

Practitioners receive 24 hours of intervention training. Booster training of practitioners is not required.

How are the practitioners supervised?

It is recommended that practitioners are supervised by one host-agency supervisor with 24 hours of intervention training.

What are the systems for maintaining fidelity?

Intervention fidelity is maintained through the following processes:

  • Training manual
  • Other printed material
  • Other online material
  • Fidelity monitoring
  • Two day-long sessions for training and sharing are hosted each year for on-site supervisors, which is cascaded to practitioners
  • Ad hoc support is provided via phone/email to supervisors as needed.

Is there a licensing requirement?

Yes

HENRY’s most rigorous evidence comes from a pre–post study conducted in the UK.

This study observed statistically significant pre–post intervention increases in the amount of healthy foods consumed by HENRY children. HENRY parents also reported improved parental self-efficacy and ability in setting limits, increased adult happiness about weight, increased adult physical activity (gardening/do-it-yourself) and reduced screen time. There were also improvements in family and adult eating behaviours, as well as frequency of healthy food consumption for adults. There was no comparison group, however.

HENRY has preliminary evidence of improving a child outcome, but we cannot be confident that the intervention caused the improvement.

Rated 3: Has evidence of a short-term positive impact from at least one rigorous study.

Rated 3+: Meets the level 3 rating and has evidence from other studies with a comparison group at level 2 or higher.

Rated 4: Has evidence of a long-term positive impact through at least two rigorous studies.
