“…Thus, the indices "dietary fibers" and "polyunsaturated fatty acids" can each range from 3 to 21, "monounsaturated fatty acids" from 8 to 56, and "saturated fatty acids" ranges from 9 to 63. This food frequency questionnaire was validated against a 7-day dietary record (n=899; applied in a previous KORA/MONICA study) with the result that it can be used for analysis on group level [26].…”

“…Details on a very similar food frequency list have been described elsewhere. 20 Definition of reversion to NGT To make sure that reversion to NGT corresponded with clinically relevant changes of glucose values, subjects with prediabetes at baseline were defined as reverters to NGT only if (1) they had isolated IFG at baseline, had NGT in the follow-up examination, and fasting glucose had decreased by more than 5 mg dl À1 between both examinations, or (2) they had isolated IGT at baseline, had NGT in the followup examination, and their 2-h glucose had decreased by more than 10 mg dl À1 between both examinations, or (3) they had combined IFG and IGT at baseline, had NGT in the follow-up examination, and either their fasting glucose had decreased by more than 5 mg dl À1 or their 2-h glucose had decreased by more than 10 mg dl À1 between both the examinations.…”

Background and aims: In a population-based cohort study with older subjects and without specific interventions, we investigated the impact of body mass index (BMI) and BMI change (as well as waist circumference and change of waist circumference) on reversion from prediabetes to normal glucose tolerance (NGT) and on long-term persistence of NGT. Materials and methods: Oral glucose tolerance tests were conducted at baseline and at follow-up in a cohort study in Southern Germany (KORA S4/F4; 1223 subjects without diabetes aged 55-74 years at baseline in 1999-2001; 887 subjects (73%), of whom 436 had prediabetes at baseline, participated in the follow-up 7 years later). Results: BMI reduction, but not initial BMI, predicted reversion from prediabetes to NGT. The odds ratio (OR) for returning to NGT was 1.43 (95% CI: 1.18-1.73) for a BMI decrease of 1 kg m À2 , after adjustment for age, sex, baseline glucose values and lifestyle factors. Initial BMI had no effect on reversion to NGT (OR ¼ 0.98, 95% CI: 0.91-1.06, per kg m À2 ). Persistence of NGT was associated with baseline BMI (OR ¼ 0.94, 95% CI: 0.88-0.998) and BMI reduction (OR ¼ 1.16, 95% CI: 1.02-1.33, per decrease by 1 kg m À2 ). For waist circumference and change of waist circumference similar results were obtained. Conclusion: In older adults, weight loss strongly increased the chances of returning from prediabetes to NGT irrespective of initial BMI. Long-term persistence of NGT depended both on initial BMI and on BMI change.

“…The participants were asked to recall their ''average intake'' of each item in the following six frequency categories: almost daily, several times per week, about once a week, several times per month, once a month or less, never. Details on a very similar FFL have been described elsewhere [15].…”

Active smoking is a risk factor for type 2 diabetes (T2DM), but it is unclear whether exposure to environmental tobacco smoke (ETS) is also associated with T2DM. The effect of passive and active smoking on the 7-year T2DM incidence was investigated in a populationbased cohort in Southern Germany (KORA S4/F4; 1,223 subjects aged 55-74 years at baseline in 1999-2001, 887 subjects at follow-up). Incident diabetes was identified by oral glucose tolerance tests or by validated physician diagnoses. Among never smokers, subjects exposed to ETS had an increased diabetes risk in the total sample (odds ratio (OR) = 2.5; 95% confidence interval (CI): 1.1, 5.6) and in a subgroup of subjects having prediabetes at baseline (OR = 4.4; 95% CI: 1.5, 13.4) after adjusting for age, sex, parental diabetes, socioeconomic status, and lifestyle factors. Active smoking also had a statistically significant effect on diabetes incidence in the total sample (OR = 2.8; 95% CI: 1.3, 6.1) and in prediabetic subjects (OR = 7.8; 95% CI: 2.4, 25.7). Additional adjustment for components of the metabolic syndrome including waist circumference did not attenuate any of these associations. This study provides evidence that both passive and active smoking is associated with T2DM.
