^†Total n = 25,391. Pooled logistic regression model. The number of observations changed at the second follow‐up period.

^‡Adjusted for nine regions, age, the term of survey (baseline to 5‐year survey or 5‐year survey to 10‐year survey), body mass index (quartile groups, missing), hypertension, parental history of diabetes, leisure‐time physical activity (none, once a week to daily, missing), intakes of coffee (none, 1–2 cups/week, 3–4 cups/week, ≥5 cups/week, and missing).
