Dietary intake habits and prevalence of nocturia in Japanese patients with type 2 diabetes mellitus

No reports have been published on the association between dietary intake habits and nocturia in the diabetes population. We therefore estimate this issue among Japanese patients with diabetes mellitus.

Study subjects in the present study were 785 Japanese patients with type 2 diabetes mellitus. Self-administrated questionnaires were used to assess each type of dietary intake habits. Vegetable intake habit was assessed by the following question: Do you have vegetables or seaweed every day?" We used the following two outcomes: 1) nocturia: ≥ 2 voids per night and 2) severe nocturia: ≥ 3 voids per night. Adjustment for age, sex, body mass index, glycated hemoglobin, hypertension, dyslipidemia, smoking, drinking, exercise habit, stroke, ischemic artery disease, diabetic nephropathy, diabetic neuropathy, and diabetic retinopathy.

The prevalence of nocturia, severe nocturia, and vegetable intake habit was 39.9%, 14.4%, and 67.3%, respectively. After adjusting for confounding factors, vegetable intake habit was independently inversely associated with nocturia and severe nocturia: the adjusted ORs were 0.67 (95% CI: 0.48-0.94) and 0.46 (95% CI: 0.30-0.71), respectively. Among male patients, vegetable intake habit was independently inversely associated with severe nocturia but not nocturia: the adjusted OR was 0.51 (95% CI 0.29-0.88). Among female patients, vegetable intake habit was independently inversely associated with nocturia and severe nocturia: the adjusted ORs were 0.44 (95% CI 0.24-0.79) and 0.34 (95% CI 0.15-0.78), respectively.

We found the inverse association between vegetable intake habit and nocturia in Japanese patients with type 2 diabetes mellitus. This article is protected by copyright. All rights reserved.
