dc.description.abstract | Background: Changing diet and physical activity behaviour is one of the cornerstones of type 2 diabetes
treatment, but changing behaviour is challenging. The objective of this study was to identify behaviour change
techniques (BCTs) and intervention features of dietary and physical activity interventions for patients with type 2
diabetes that are associated with changes in HbA1c and body weight.
Methods: We performed a systematic review of papers published between 1975–2015 describing randomised
controlled trials (RCTs) that focused exclusively on both diet and physical activity. The constituent BCTs, intervention
features and methodological rigour of these interventions were evaluated. Changes in HbA1c and body weight
were meta-analysed and examined in relation to use of BCTs.
Results: Thirteen RCTs were identified. Meta-analyses revealed reductions in HbA1c at 3, 6, 12 and 24 months of -1.
11 % (12 mmol/mol), -0.67 % (7 mmol/mol), -0.28 % (3 mmol/mol) and -0.26 % (2 mmol/mol) with an overall
reduction of -0.53 % (6 mmol/mol [95 % CI -0.74 to -0.32, P < 0.00001]) in intervention groups compared to control
groups. Meta-analyses also showed a reduction in body weight of -2.7 kg, -3.64 kg, -3.77 kg and -3.18 kg at 3, 6, 12
and 24 months, overall reduction was -3.73 kg (95 % CI -6.09 to -1.37 kg, P = 0.002).
Four of 46 BCTs identified were associated with >0.3 % reduction in HbA1c: ‘instruction on how to perform a
behaviour’, ‘behavioural practice/rehearsal’, ‘demonstration of the behaviour’ and ‘action planning’, as were
intervention features ‘supervised physical activity’, ‘group sessions’, ‘contact with an exercise physiologist’, ‘contact
with an exercise physiologist and a dietitian’, ‘baseline HbA1c >8 %’ and interventions of greater frequency and
intensity.
Conclusions: Diet and physical activity interventions achieved clinically significant reductions in HbA1c at three and
six months, but not at 12 and 24 months. Specific BCTs and intervention features identified may inform more
effective structured lifestyle intervention treatment strategies for type 2 diabetes. | en_IE |
