Effect of a nutrition education programme on metabolic risk factor and metabolic syndrome in adults with type 2 diabetes mellitus at a Level 5 Hospital in Kenya: “a randomized controlled trial”
Abstract Background Type 2 diabetes mellitus; a chronic disorder characterized by poor glycemic control, is a life threatening condition of global public health concern which worsens in the presence of metabolic syndrome (MetS) and associated risks. However application of lifestyle intervention may reduce this risk. The aim of the current study was to evaluate the effect of nutrition education programme with inclusion of peer to peer support on MetS and Mets risk factors in type 2 diabetes mellitus patient. Methods This was a randomized controlled trial with two intervention groups and one control. The intervention groups included nutrition education peer to peer support group (NEP) (n=51) and nutrition education group (NE) (n=51) which participated in an eight week (2 h per week) group nutrition education sessions and follow-up sessions for six month. The NEP in addition had a peer to peer support component on weekly basis for the eight weeks of training and monthly support for six months. The control group (C) (n 51) received standard care. Outcomes were assessed at 6 months. An intention-to-treat analysis was conducted using analysis of co-variance (ANCOVA).Results: Differences in MetS were -38.1 and -31.7% (P<0.01) at 6 months in the NEP group as per Harmonized and WHO criteria respectively. Significant improvement was seen in number of participant achieving recommended waist circumference; WC (33.9 %) and high density lipoprotein; HDL (35.2%) in the NEP group and blood pressure; BP (reduction by 39.2 and 31.6) as per harmonized and WHO criteria respectively in the NE group. six month post intervention Statistical mean change was also noted six month post intervention in; weight lost (-6.26kg), BMI (-2.37 kg/m2), waist hip ratio; WHR (-0.03), WC (-14.51 cm) and HDL (+0.34mmol/l in the NEP group and diastolic blood pressure; DBP (-5.17 mmhg) in the NE group. Comparison of the NEP and NE with control showed that NEP and NE had better outcome.Conclusions: Nutrition education with inclusion of peer to peer support was of clinical benefit in reducing metabolic outcomes and MetS in Type 2 diabetes mellitus patient. Optimal goal setting and self-effective training could benefit future nutrition education programmes with peer to peer support component for people with Type 2 Diabetes and at risk of Mets.
