Pilot Study of Behavioural Intervention for Nutrition in Cystic Fibrosis
- Conditions
- Cystic Fibrosis
- Interventions
- Behavioral: Behaviour change intervention
- Registration Number
- NCT01957072
- Brief Summary
Cystic Fibrosis (CF) is a lifelong condition which causes the lungs and digestive system to become clogged with thick, sticky mucus. This leads to recurrent lung infections and reduced nutrients absorption from food. The average age at death is 26 years, usually from respiratory failure. Nonetheless, the nutritional status of people with CF (PWCF) is important help them live healthier and longer.
It is recommended that adult with CF achieve a BMI of 23 for males and 22 for females. However, fewer than 50% adult with CF achieved that target BMI despite effective nutritional support to help support weight gain. There is a clear need for a behavioural intervention that can help PWCF use the available nutritional support.
This is a feasibility study to try out a multi-component behavioural intervention. The intervention is designed to help PWCF use their nutritional support to gain weight. It will focus on testing the methods and procedures to be used on a larger scale, improving the behavioural intervention and estimating the how many people are needed for the larger trial.
All eligible 75 PWCF in Sheffield will be invited to participate. The investigators anticipate recruiting 30 participants. Participants will be divided into two groups. The first group receive the behavioural intervention immediately. The second group receive the intervention after 3 months. All participants will be followed up for 6 months. Data will be collected every 6 weeks during clinic reviews.
These two groups will be compared against each other to estimate the potential impact of the behavioural intervention. The investigators will also interview some of the participants at the end of the study period to improve the intervention and the study processes based on participant feedback.
The investigators hypothesised that this study will recruit around 30 participants, around 80% of the participants will complete the study, a single full-time investigator can deliver the intervention to 15 participants over 3 months and data collection will be thorough (with less than 5% missing data). The investigators also hypothesised that this feasibility study will help improve the intervention and help the design of a larger trial.

- Primary Outcome Measures
Name Time Method Proportion of patients who accepted invitation to participate as a marker of feasibility 4 weeks Proportion of people with CF who are randomised into the study after accepting the invitation to participate, as a marker of feasibility 4 weeks
- Secondary Outcome Measures
Name Time Method Resources needed by the investigators to deliver the intervention 6 months Participants' opinion about the behavioural intervention 6 months Participant attrition rate and phases of study whereby the attrition occurs 6 months Proportion of days with missing nutritional data, as a marker for feasibility 6 months Participants are requested to fill in their nutritional intake daily on a web-based food diary. The investigators are interested to find out what the proportion of such data will be missing to determine the feasibility of collecting data with the web-based food diary.
Participants' opinion about the study processes 6 months Participants' suggestions for further improvement of the intervention and study processes 6 months Proportion of adults who fulfils the BMI criteria for recruitment with IT facilities 2 weeks
