Management of type 2 diabetes in New Zealand: a scoping review of interventions with measurable clinical outcomes.

OBJECTIVE: This review aimed to assess the effectiveness of interventions for type 2 diabetes (T2D) management in New Zealand on clinical outcomes, and explore the factors impacting their feasibility and acceptability. STUDY DESIGN: Scoping review. METHODS: Three databases (PubMed, Web of Science and Scopus) were searched between January 2000 and July 2023. Reference lists of included studies were hand searched to identify additional articles. RESULTS: The search yielded 550 publications, of which 11 were included in the final review. Most interventions (n = 10) focussed on education and seven were delivered by health professionals. Supporting factors for interventions included clinical/peer support (n = 8) and whanau (family) involvement (n = 6). Hindering factors included non-adherence (n = 4) and high drop-out (n = 4). Most studies reported modest improvement in HbA1c and weight at six months, but minimal change in HbA1c, weight, lipids, renal profile, and blood pressure by two years. CONCLUSION: Future interventions should involve culturally appropriate approaches to improve engagement and acceptability while addressing lifestyle and medication adherence for T2D management. T2D interventions not widely disseminated via academic channels need to be further identified.

The long-term effects of feeding honey compared with sucrose and a sugar-free diet on weight gain, lipid profiles, and DEXA measurements in rats.

To determine whether honey and sucrose would have differential effects on weight gain during long-term feeding, 45 2-mo-old Sprague Dawley rats were fed a powdered diet that was either sugar-free or contained 7.9% sucrose or 10% honey ad libitum for 52 wk (honey is 21% water). Weight gain was assessed every 1 to 2 wk and food intake was measured every 2 mo. At the completion of the study blood samples were removed for measurement of blood sugar (HbA1c) and a fasting lipid profile. DEXA analyses were then performed to determine body composition and bone mineral densities. Overall weight gain and body fat levels were significantly higher in sucrose-fed rats and similar for those fed honey or a sugar-free diet. HbA1c levels were significantly reduced, and HDL-cholesterol significantly increased, in honey-fed compared with rats fed sucrose or a sugar free diet, but no other differences in lipid profiles were found. No differences in bone mineral density were observed between honey- and sucrose-fed rats, although it was significantly increased in honey-fed rats compared with those fed the sugar-free diet.

The effect of honey compared to sucrose, mixed sugars, and a sugar-free diet on weight gain in young rats.

To determine whether honey, sucrose, and mixed sugars as in honey have different effects on weight gain, 40 6-wk-old Sprague-Dawley rats were fed a powdered diet that was either sugar free or contained 8% sucrose, 8% mixed sugars as in honey, or 10% honey freely for 6 wk. Weight gain and food intake were assessed weekly, and at completion of the study blood samples were removed for measurement of blood sugar (HbA1c) and a fasting lipid profile. The animals were then minced and total percentage body fat and protein measured. Overall percentage weight gain was significantly lower in honey-fed rats than those fed sucrose or mixed sugars, despite a similar food intake. Weight gains were comparable for rats fed honey and a sugar free diet although food intake was significantly higher in honey-fed rats. HbA1c and triglyceride levels were significantly higher in all sugar treatments compared with rats fed a sugar free diet, but no other differences in lipid profiles were reported. No differences in percentage body fat or protein levels were reported.
