Study summary

Control of body weight (BW) is important to prevent and manage type 2 diabetes. Regardless of the close association, little is understood about the precise relationship between BW and glycemic control, which might be of benefit for patients with type 2 diabetes. The researchers investigated the correlation between changes in BW and glycemic control in patients with type 2 diabetes treated with a diet therapy or pioglitazone.

Groups and cohorts

  • 1 (type 2 diabetes, body weight, HbA1c)

    The investigators analyzed the recorded data (body weight and glycohemoglobin) of 70 type 2 diabetic patients treated with the diet therapy. Recorded values at 0, 2 and 4 months for body weight (BW) and glycohemoglobin (HbA1c) were used. And changes from baseline (0 month) in BW (ΔBW) were plotted against those of HbA1c (ΔHbA1c).

  • 2 (type 2 diabetes, pioglitazone, HbA1c)

    The investigators analyzed the recorded data (body weight and glycohemoglobin) of 23 type 2 diabetic patients treated with pioglitazone. Recorded values at 0, 2 and 4 months for body weight (BW)and glycohemoglobin (HbA1c) were used. And changes from baseline (0 month) in BW (ΔBW) were plotted against those of HbA1c (ΔHbA1c).
