In a dietary study, control food products could be provided as a means of maintaining both contact and participant interest. Keywords: Dietary intervention trial, Attrition, How. Table 3.

There are many challenges involved in running randomised controlled dietary intervention trials that investigate health outcomes. The aim of this paper was to evaluate the recruitment process, retention of participants and challenges faced in our dairy intervention trial, and to provide strategies to combat the difficulties of running long-term dietary intervention trials. A month, randomised, two-way crossover study was conducted in overweight adults with habitually low dairy food consumption to assess the effects of a high dairy intake 4 servings of reduced-fat dairy per day compared with a low dairy intake 1 serving of reduced-fat dairy per day on measures of cardiometabolic and cognitive health. On completion of the high dairy intake phase, each participant was interviewed about their experience in the trial and responses were used to evaluate the key issues for study participants. Although the recruitment target was achieved, high rates of attrition Factors that contributed to the high attrition included inability to comply with the dietary requirements of the study protocol Attrition and adherence to study requirements present challenges to trials requiring longer-term dietary change. Including a run-in period to further assess the motivation, commitment and availability of participants, maintaining regular contact with participants during control phases, minimising time commitment, providing flexibility with dietary requirements, facilitating positive experiences, and stringent monitoring of diet are some key recommendations for future dietary intervention trials. This month dietary intervention trial was designed to assess the effects of a high intake of reduced-fat dairy food on cardiometabolic and cognitive health in overweight, habitually low dairy consumers. The difficulties of running longitudinal studies and randomised controlled trials to investigate health outcomes are well recognised [ 1 – 4 ]. Implementing a dietary intervention to assess physical and psychological outcomes of increased dairy consumption presented multiple challenges, including recruitment of interested volunteers and maintaining subject compliance, both critical for the success of any health research.

Dairy products included a selection of reduced-fat milk, yogurt and custard, and were provided based on personal preference. The results of this RCT provide support for improving diet as a useful adjunct treatment to reduce depressive symptoms. This study therefore contributes to a body of research suggesting that despite many perceived barriers, nutritional intake can be modified in youth with mental health issues.

All participants were instructed to maintain their normal physical activity for the duration of the study.
