Abstract Background Diet is central to treatment of type 2 diabetes. This review aimed to compare the effectiveness of nutrition therapy delivered by dietitians to nutrition advice delivered by other healthcare professionals in adults with type 2 diabetes on metabolic parameters. Methods Cochrane CENTRAL, CINAHL, EMBASE, MEDLINE and PsychINFO were searched for randomised controlled trials of three months duration or longer, published from 1st January 2008 to 18th June 2019. Relevant data were extracted from studies with additional author information. Random-effects meta-analysis assessed mean changes in HbA1c and other clinical parameters. PROSPERO registration number: CRD42019130528. Results Of 2477 records identified, fourteen studies (n = 3338) were eligible for qualitative synthesis and meta-analysis. The mean changes [95% CI] at follow-up in HbA1c, BMI, weight, LDL cholesterol, systolic and diastolic blood pressure were − 0·47 [-0·92, -0·02] %, -0·38 [-0·63, -0·13] kg/m2, -1·49 [-2·14, -0·84] kg, -0·15 [-0·33, 0·04] mmol/L, -0·75 [-2·45, 0·96] mm Hg and − 1·17 [-4·52, 2·17] mm Hg respectively in favour of the intervention group. Conclusions Nutrition therapy provided by dietitians was associated with better clinical parameters of type 2 diabetes, including clinically significant improved glycaemic control, across diverse multiethnic patient groups from all six inhabited continents. This conclusion should be reflected in clinical guidelines.

Abstract Objectives Nutrition therapy is crucial for the treatment of type 2 diabetes. Preliminary data indicate that nutrition therapy delivered by accredited dietitians achieves better clinical outcomes than when delivered by other healthcare professionals. We compared dietetic intervention provided by accredited dietitians with nutrition advice provided by other healthcare professionals. Methods Systematic literature review and meta-analysis of RCTs of type 2 diabetes management programmes (3 months or more) implementing medical nutrition therapy and reporting changes in haemoglobin A1c (HbA1c) and other clinical outcomes that have been published in CENTRAL, CINAHL, EMBASE, MEDLINE and PsychINFO between 2008 to 18th June 2019. Results Seven studies with a total of 950 participants were included in the meta-analysis. The mean changes [95% CI:] at six or twelve months follow-up in HbA1c, BMI, weight and low-density lipoprotein (LDL) were –0.37 [–0.56, –0.19], –0.56 [–1.14, 0.02], –2.40 [–3.59, –1.20] and –0.16 [–0.29, –0.02] respectively in favour of the intervention group. Conclusions Nutrition intervention provided by a dietitian results in better clinical outcomes of type 2 diabetes, compared with that delivered by other healthcare professionals. Further longitudinal randomised studies are warranted to elucidate long-term (more than one year) effects of the interventions. Funding Sources Nil funding.

Background: Many clinical trials have been conducted to verify the effects of interventions for prevention of type 2 diabetes (T2D) using different treatments and outcomes. The aim of this study was to compare the effectiveness of lifestyle modifications (LM) with other treatments in persons at high risk of T2D by a network meta-analysis (NMA). Methods: Searches were performed of PUBMED up to January 2018 to identify randomized controlled trials. The odds ratio (OR) with onset of T2D at 1 year in the intervention group (LM, dietary, exercise, or medication) versus a control group (standard treatments or placebo) were the effect sizes. Frequentist and Bayesian NMAs were conducted. Results: Forty-seven interventions and 12 treatments (20,113 participants) were used for the analyses. The OR in the LM was approximately 0.46 (95% CI: 0.33 to 0.61) times lower compared to the standard intervention by the Bayesian approach. The effects of LM compared to other treatments by indirect comparisons were not significant. Conclusions: This meta-analysis further strengthened the evidence that LM reduces the onset of T2D compared to standard and placebo interventions and appears to be at least as effective as nine other treatments in preventing T2D.

Balance impairments are a relevant problem in patients with diabetes, and interventions to manage this issue represent a public health need. This study reviewed the literature about the effectiveness of Tai Chi on balance improvement in patients with type 2 diabetes. Springerlink, MEDLINE, PubMed, CINAHL, Web of Science, Scopus, and Cochrane CENTRAL databases were screened. Randomized and nonrandomized controlled trials assessing balance in patients with type 2 diabetes enrolled in a Tai Chi program were considered eligible. Four studies were included in qualitative synthesis and in quantitative analysis (three randomized controlled trials and one pretest–posttest quasi-experimental study). Evidence supporting Tai Chi to improve balance in patients with type 2 diabetes was found (effect size: 0.52; 95% confidence interval [0.20, 0.84]); however, the analysis relied on a small number of studies, which raises concerns about the risk of bias. In conclusion, the results support the benefits of Tai Chi intervention to improve balance in patients with type 2 diabetes.

Background: Diabetes mellitus is a chronic, degenerative disease, requiring a multi-dimensional, multi-professional care by healthcare providers and substantial self-care by the patients, to achieve treatment goals. Objective: To evaluate the impact of pharmacist-led care on glycaemic control in patients with uncontrolled Type 2 Diabetes Methods: In a parallel group, single-blind randomised controlled study; type 2 diabetic patients, with greater than 7% glycated haemoglobin (A1C) were randomised into intervention and usual care groups and followed for six months. Glycated haemoglobin analyzer, lipid analyzer and blood pressure monitor/apparatus were used to measure patients’ laboratory parameters at baseline and six months. Intervention group patients received pharmacist-structured care, made up of patient education and phone calls, in addition to usual care. In an intention to treat analysis, Mann-Whitney U test was used to compare median change at six months in the primary (A1C) and secondary outcome measures. Effect size was computed and proportion of patients that reached target laboratory parameters were compared in both arms. Results: All enrolled participants (108) completed the study, 54 in each arm. Mean age was 51 (SD 11.75) and majority were females (68.5%). Participants in the intervention group had significant reduction in A1C of -0.75%, compared with an increase of 0.15% in the usual care group (p<0.001; eta-square= 0.144). The proportion of those that achieved target A1C of <7% at 6 months in the intervention and usual care group was 42.6% vs 20.8% (p=0.02). Furthermore, intervention patients were about 3 times more likely to have better glucose control; A1C<7% (aOR 2.72, 95%CI: 1.14-6.46) compared to usual care group, adjusted for sex, age, and duration of diabetes. Conclusions: Pharmacist-led care significantly improved glycaemic control in patients with uncontrolled T2DM.
