Study type
Description of intervention(s) / exposure
The intervention is the second phase of a two phase project. Phase 1 (a community RCT) is described in ACTRN12610000608066

Phase 2 will follow the same methodology as Phase 1 and will be conducted in 5 Local Government Areas of the Hunter Valley Region, NSW, Australia (Maitland, Singleton, Muswellbrook, Scone, Cessnock). In short, the duration of the intervention is 8 sessions over 12 weeks. The intervention involves fathers attending eight 90 minute face to face information sessions (including 4 interactive sessions with their children). The program includes: physical activity components; dietary and nutritional information; a self-monitoring component. More specifically program sessions focus on: 1) sustainable weight loss for men; identification of healthy and unhealthy lifestyle behaviours and explanation of the use of role modelling and positive reinforcement; 2) father and child engagement in a variety of physical activities to develop child's confidence and ability in performing various fundamental movement skills; 3) the importance of fathers for children's physical activity levels; strategies for encouraging physical activity in children; 4) another session for father and child engagement in a variety of physical activities; 5) nutritional information to encourage healthy eating for fathers and children; 6) Father and child games and fun physical activities as well as a focus on positive family traditions and rituals 7) sustaining healthy eating patterns for the family; 8) father and child engagement activities and closure.

Fathers will also receive behavioural procedures over the course of the program via the use of the online website The key constructs of social cognitive theory will be operationalised in the sessions (self efficacy, self monitoring, goal setting and social support).

When translating evidence-based programs into real-world settings, ongoing modifications are required based on the unique characteristics of the settings and populations. Modifications will be made to the program based on both outcome and process evaluation from the community RCT (phase 1) and each subsequent program implementation in 2011 and 2012 and these will be documented. The goal will be to develop a comprehensive model of a real-world intervention for application in communities through updating materials, developing standardized train-the-trainer education and resources and ongoing evaluation of the implementation of the intervention with a final evaluation conducted in 2012/13.

Secondary outcome [3] 299385 0
Physical activity of fathers is measured using a modified version of the Godin Leisure-Time Exercise Questionnaire (GLTEQ) and the Children's Leisure Activities Study Survey (CLASS) questionnaire is completed by the father with the eldest child as the reference.

Dietary intake for fathers. A modified version of the Australian Eating Survey relating to 8 key nutritional messages is completed by fathers. This questionnaire is also completed by fathers as proxy for their eldest child.
Timepoint [4] 299386 0
At baseline and at 3, 6 and 12 month follow-up.
Secondary outcome [5] 299387 0
Parenting strategies: Parental engagement is measured using a modified version of the Parental Engagement survey used in Phase 1. Fathers will complete the questionnaire in reference to their eldest child. Parenting strategies for physical activity and nutrition are measured using a validated questionnaire. Attitudes to rough and tumble play are assessed via a semi-structured interview with a limited number of participants.
Timepoint [5] 299387 0
For the questionnaires: At baseline and at 3, 6 and 12 month follow-up. The semi-structured interview is to occur prior to the baseline assessment in a select number of participants.
Secondary outcome [6] 299388 0
Sedentary behaviour measured in fathers using the Modified sitting questionnaire and proxy-report for children (completed by fathers) using the Indoor based activites section of the CLASS questionnaire.
Timepoint [6] 299388 0
At baseline and at 3, 6 and 12 month follow-up.

Secondary outcome [8] 299390 0
Alcohol Consumption is self reported by fathers using a Modified Alcohol Use Disorders Identification Test 2009
Timepoint [8] 299390 0
At baseline and at 3, 6 and 12 month follow-up.

Brief summary
It is well established that parents of primary school aged children substantially influence the food and physical activity home environment through behaviours, attitudes, feeding styles and role modelling. However, the contribution of fathers’ influence on children’s physical activity and eating behaviour is often overlooked.The Healthy Dads Healthy Kids (HDHK) project is based on research that shows the eating habits and exercise routine of fathers and father figures influence the ways in which the whole family approaches their health. The program was developed and successfully trialled at the University of Newcastle, with trial results showing that the major aims of HDHK were achieved. These were (i) to help overweight/obese fathers achieve a healthy weight, and (ii) to improve the activity and eating behaviours of their children (using fathers as the key agents of behaviour change). Phase 1 of the HDHK community effectiveness trial (
) was to evaluate the impact of the program in a community setting with trained local facilitators, employing a RCT design. The intention of this current project (Phase 2) is to research the effectivenss of the HDHK program on a larger scale community roll-out using a non-randomized, prospective design.
