¹Weight non-gain included individuals who lost weight and those who maintained their body weight within 3% of the baseline weight. ²Using a logistic regression model with weight gain of >3% body weight versus no weight gain. ³A six-level age-sex variable was created, using 30 year old men as the reference group. ⁴Fasting glucose <7.0 mmol/L and 2-hour capillary plasma glucose after a 75 g glucose load (oral glucose tolerance test) ≥ 8.9 to <12.2 mmol/L and without diagnosis of diabetes type 2 [21]. ⁵Diabetes mellitus defined as self-report, fasting blood glucose of ≥7.0 mmol/L, or 2-hour capillary plasma glucose (oral glucose tolerance test) of ≥12.2 mmol/L [21].
