Study summary

The goal of this study is to learn if a parent-child dyadic physical activity (PA) intervention works to improve physical activity levels in children with leukaemia. It will also learn about the intervention's effects on children's self-confidence in doing physical activity and their quality of life. The main questions it aims to answer are:

Does the dyadic PA intervention increase the amount of physical activity children do, compared with an individual PA intervention or usual care? Does the dyadic PA intervention improve children's confidence in doing physical activity and their overall quality of life? What is the cost-effectiveness of the dyadic intervention relative to the individual intervention and psychological support control group?

Researchers will compare three groups: children and parents doing physical activity together (dyadic intervention), children doing physical activity individually (individual intervention), and children receiving psychological support sessions only (control group), to see if involving parents makes a difference.

Participants will:

Attend weekly sessions for 3 months (12 sessions total) Wear an activity tracker for 7 days and complete questionnaires at 5 different time points over 12 months Some participants will also be invited to take part in an interview about their experience

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Children aged 9-18 years old
  • Diagnosed with leukaemia
  • Currently undergoing maintenance therapy
  • Have a parent willing to participate in the study
  • Both the child and participating parent speak Cantonese and read Chinese

Exclusion criteria

Exclusion Criteria:

  • Children under palliative care with evidence of cancer recurrence or second
  • Children with medical for PA, such as thrombosis, as documented by physicians
  • Children or parents with physical impairment or cognitive and learning problems (identified from medical records)
  • Participants in the team's other interventional studies
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Study arms

  • Experimental
    Dyadic Intervention

    Parent-child dyads complete a 3-month, 12-session physical activity program together, with intensity tailored to each child.

    Behavioral: Dyadic Physical Activity Intervention

  • Active comparator
    Individual Intervention

    Children complete the same 3-month, 12 weekly sessions physical activity program as the dyadic group, but without parental participation.

    Behavioral: Individual Intervention

  • Active comparator
    Control

    Children receive 12 weekly sessions of simple psychological support over 3 months, without a physical activity component.

    Behavioral: Psychological Support

Interventions

  • BehavioralDyadic Physical Activity Intervention

    Parent-child dyads receive a structured physical activity intervention delivered by a trained Research Assistant over 12 weekly sessions across 3 months. Parents perform the physical activity together with their child in each session. Exercise intensity is individually tailored to each child.

  • BehavioralIndividual Intervention

    Children receive the same structured 12-session, weekly physical activity intervention as the dyadic group, delivered over 3 months by a trained Research Assistant, without parental participation. Exercise intensity is individually tailored to each child.

  • BehavioralPsychological Support

    Children receive 12 weekly sessions of simple psychological support over 3 months, delivered by a trained Research Assistant, without a physical activity component.

What researchers measure

Primary outcomes

  1. Physical Activity Level

    Children's physical activity levels will be objectively measured using ActiGraph GT3X accelerometers, worn for 7 consecutive days at each assessment timepoint. The primary outcome is the minutes engaged in moderate-to-vigorous physical activity (MVPA).

    Time frame: Baseline and 12 months(T4)

Secondary outcomes

  1. Self-Reported Physical Activity Level

    Children's self-reported PA levels measured using the Chinese University of Hong Kong: Physical Activity Rating for Children and Youth, an 11-point scale (0-10) asking children to self-rate their PA levels in the past 7 days, from 0 (no exercise at all) to 10 (vigorous exercise on most days).

    Time frame: Baseline, 3 months (T1), 6 months (T2), 9 months (T3), and 12 months (T4)

  2. Health-Related Quality of Life Score (EQ-5D-Y-5L)

    Children's health-related quality of life will be measured using the EQ-5D-Y-5L. It includes a descriptive system covering five health dimensions, each scored from 1 to 5, with higher scores indicating worse outcomes, and the EQ visual analogue scale , scored from 0 to 100, with higher scores indicating better outcomes.

    Time frame: Baseline, 3 months (T1), 6 months (T2), 9 months (T3), and 12 months (T4)

  3. Physical Activity Self-Efficacy Score

    Children's physical activity self-efficacy will be assessed using the five-item Physical Activity Self-Efficacy Scale. Each item is rated on a three-point Likert scale. Total scores range from 5 to 15, with higher scores indicating greater physical activity self-efficacy.

    Time frame: Baseline, 3 months (T1), 6 months (T2), 9 months (T3), and 12 months (T4)
