Clinical Trial Summary

To investigate whether the interactive family based lifestyle programme leads to behaviour change at 6 months with the primary outcome being increased levels of moderate to vigorous physical activity (MVPA).

Description:

To investigate whether the lifestyle programme results in changes to the following outcomes 3 and 6 months after baseline assessment (Child)

• An increase in objectively measured total amount of physical activity

• An increase in the proportion meeting MVPA guidelines (measured objectively)

• Reduction in time spent sedentary (measured objectively and self-reported)

• Change in self-reported physical activity

• Reduction in measures of adiposity (body mass index percentile, per cent body fat)

• Improvement in psychological factors that may mediate physical activity participation (self-efficacy, motivation, attitudes, social support and enjoyment of physical activity; and physical self-perceptions)

• Change in healthy food provision and parenting practices for healthy food

• Improvement in diet composition.

• Improvement in knowledge of physical activity and nutrition.

• Improvement in cardio-metabolic variables (blood pressure, glucose, HbA1c, cholesterol)

The Investigators will also include qualitative data collected from:

• Evaluation forms following each intervention workshop session which will be completed by the Parent/guardian, child and facilitator

• Feedback from focus groups to be held following completion of the total intervention i.e. 8 sessions

To investigate whether the lifestyle programme results in changes to the following outcomes 3 and 6 months after baseline assessment (Parent(s)/guardian(s))

• An increase in objectively measured total volume of physical activity

• An increase in the proportion meeting MVPA guidelines (measured objectively)

• Reduction in time spent sedentary (measured objectively and self-reported)

• Change in self-reported physical activity

• Reduction in measures of adiposity (body mass index percentile, per cent body fat)

• Change in healthy food provision and parenting practices for healthy food

Parents/guardians will answer questions in the eligibility questionnaire about their child and family health history. Participants will be invited to participate if they are 12-14 years old inclusive (12 years 0 days to 14 years 354 days old) and are identified as having the following risk factors for development of Type 2 Diabetes (which will be identified from the eligibility questionnaire):

BMI > 85th percentile PLUS one other from the following list:

• Family history of Diabetes (first degree relative).

• Non-white ethnicity.

Exclusion Criteria:

Young people will not be eligible for participation in the study if they are outside the age range of interest (<11 years and 364 days or >14 years and 1 day), have an existing diagnosis of Type 1 or Type 2 Diabetes, < 85th percentile. Young people will also be excluded if they themselves do not provide written assent or their parent/guardian does not provide written consent.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	The primary endpoint is to detect a change in objectively measured MVPA of 10 minutes per day within the intervention group at 6 months.	Participating children and adults will be asked to wear the wrist worn GENEActiv accelerometer (ActivInsights, Kimbolton, Cambridgeshire, UK) continuously for up to 8 days.	6 months post baseline
Secondary	An increase in total volume of physical activity	Participating children and adults will be asked to wear the wrist worn GENEActiv accelerometer (ActivInsights, Kimbolton, Cambridgeshire, UK) continuously for up to 8 days.	3 and 6 months
Secondary	An increase in the proportion meeting MVPA guidelines	Participating children and adults will be asked to wear the wrist worn GENEActiv accelerometer (ActivInsights, Kimbolton, Cambridgeshire, UK) continuously for up to 8 days.	3 and 6 months
Secondary	Reduction in time spent sedentary	Participating children and adults will be asked to wear the wrist worn GENEActiv accelerometer (ActivInsights, Kimbolton, Cambridgeshire, UK) continuously for up to 8 days.	3 and 6 months
Secondary	Change in physical activity levels	Self reported - questionnaire	3 and 6 months
Secondary	Reduction in Body mass index percentile (BMI)	Body mass will be measured to the nearest 0.1kg and height will be measured to the nearest 0.1 cm using a clinically approved bioelectrical impedance scale and a portable stadiometer, respectively. BMI will be calculated as weight/height2 and will be converted to a BMI percentile based on WHO growth charts	3 and 6 months
Secondary	Change in healthy food provision and parenting practices for healthy food	As parents are active participants in the intervention The Investigators will also query their knowledge and attitudes towards healthy eating and physical activity.	3 and 6 months
Secondary	Improvement in diet composition	The Investigators will query the nutrition habits of participants to investigate any changes in the behaviours targeted in the workshops. A food frequency questionnaire (FFQ) taken from the ISCOLE study that was adapted from the HBSC Study will be used to query the consumption of 23 food categories in a "usual" week. The Investigators will also query breakfast consumption for weekdays and weekends. The Investigators have also created ad hoc questions on other intervention targets of snacking behaviours, fruit and vegetable intake and fizzy drink consumption. This ad hoc method has been used in other international multi-site studies.	3 and 6 months
Secondary	Improvement in knowledge of physical activity and nutrition	The physical activity questionnaire for adolescents (PAQ-A) [62] will be used to assess the Types and context of physical activity in order to investigate changes in the Types of sports/exercise/activities the participating child may participate in (information which is not available from the accelerometer or the majority of other validated self-report questionnaires). This questionnaire requests responses for the last 7 days by asking participants to check a list of activities for frequency of participation. This questionnaire has received support from an expert panel and has also high validity against objective measures and moderate reliability.	3 and 6 months
Secondary	Improvement in HbA1c	Biochemical measures (Child only) - HbA1c	3 and 6 months
Secondary	Improvement in Triglycerides	Biochemical measures (Child only) - Triglycerides	3 and 6 months
Secondary	Improvement in Glucose	Biochemical measures (Child only) - Glucose	3 and 6 months
Secondary	Improvement in HDL-C	Biochemical measures (Child only) HDL-C	3 and 6 months
Secondary	Improvement in Total Cholesterol	Biochemical measures (Child only) -Total cholesterol will be measured using a point-of-care testing (POCT) and LDL-C will be calculated.	3 and 6 months
Secondary	Improvement in cardio-metabolic variables	Biochemical measures (Child only) - Capillary blood samples will be taken from each child using the finger prick method. The CardioChek® system will be used as the POCT method. The CardioChek® system is a portable hand held device that requires between 15 to 40 µL capillary sample from a finger-stick for each test. The CardioChek® system is certified by the Cholesterol Reference Method Laboratory Network (CRMLN) and National Cholesterol Education Program (NCEP), is FDA-cleared, CE-marked, internationally registered, and is CLIA-waived by the Centers for Medicare & Medicaid Services, USA.	3 and 6 months
Secondary	Blood Pressure (Child)	Arterial blood pressure will be measured using an automated sphygmomanometer with an appropriate sized cuff while the patient is seated, and having rested quietly for 5 minutes. Three measurements will be obtained for blood pressure and an average of the last two will be used in any analysis.	3 and 6 months
Secondary	Blood Pressure (Parent(s)/guardian(s))	Arterial blood pressure will be measured using an automated sphygmomanometer with an appropriate sized cuff while the patient is seated, and having rested quietly for 5 minutes. Three measurements will be obtained for blood pressure and an average of the last two will be used in any analysis.	3 and 6 months
