Changes in cognitive measures in a randomized controlled trial of a health promotion program for couples targeting diet and physical activity.

Purpose: To examine cognitive responses to a 4-month health promotion program targeting diet and physical activity in recently cohabiting couples.

Design: A three-group randomized controlled trial: no intervention (Controls), interactive group sessions and mail-outs (Interactive), and one group session followed by mail-outs (Mail).

Setting: Australian research studies unit.

Physical activity and nutrition programs for couples: a randomized controlled trial.

Diet and physical activity habits may deteriorate after cohabitation, leading to weight gain and increased risk of lifestyle diseases. We carried out a 4-month, randomized controlled trial of a diet and physical activity program for couples with a 1-year follow-up, comparing two methods of delivery. The program used six modules, which, after an initial group session, were mailed to the low-level intervention group.

An innovative program for changing health behaviours.

Health-related behaviours affecting diet, weight control and physical activity are important for long-term cardiovascular health but behaviour change is difficult to initiate and even more difficult to maintain. We have developed a health promotion program, in which social support has a key role, to encourage a prudent diet, weight control and physical activity. Behaviour change is based on evaluating initial behaviour, weighing up costs and benefits, assessing barriers to change and goal-setting.
