Short- and long-term effects of a need-supportive physical activity intervention among patients with type 2 diabetes mellitus: A randomized controlled pilot trial

View Article: PubMed Central - PubMed

ABSTRACT

Objective: This pilot trial evaluated the short- and long-term effects of a six-week need-supportive physical activity (PA) intervention among patients with type 2 diabetes mellitus, on health-related (HbA1c and physical fitness) and behavioral (objectively-measured and self-reported PA) outcomes.

Methods: To support the basic psychological needs for autonomy, relatedness and competence, the intervention included one in- and outtake session with a PA coach, an individualized PA program and a weekly PA group session. The intervention was set up in collaboration with a health insurance fund and with general practitioners. A total of forty-eight patients participated in the study and were randomly assigned to an intervention (n = 27) or a waiting-list control condition (n = 21).

Results: Linear mixed models did not reveal any significant interaction effects between time and condition (ps > .05). However, significant time effects across conditions were found: a decrease in HbA1c at short term and increases in self-reported PA at both short and long term and in physical fitness at long term (ps < .05).

Conclusion: Although the intervention as a whole did not produce the expected impact, there seems a potential for brief but regular expert visit and measurement.

Mentions: All forty-eight participants (27 IC, 21 CC) signed an informed consent form and received medical approval by their GP. Thirty-six participants (20 IC, 16 CC) paid the full fee of €124.9, nine participants (5 IC, 4 CC) paid a reduced rate of €74.9 because of their low income, and three participants (2 IC, 1 CC) ended their participation prematurely before payment. The reasons for this premature cessation were practical difficulties (in two occasions) and/or different expectations (in two occasions). Of the forty-five remaining participants, forty-two participants completed the study, twenty-three in the IC and nineteen in the CC. The reasons for drop-out were practical difficulties (n = 1) or different expectations (n = 1) in the IC, or a waiting period that was too long (n = 1) in the CC. Fig 1 summarizes the recruitment process flow. This study (ML9981) was approved by the Medical Ethics Committee of the University Hospitals Leuven (ClinicalTrialsID: NCT02064335).
