Introduction: Dietary energy-dense
foods predispose to obesity and may be associated with risk of type 2 diabetes
therefore, the aim of our study was to investigate the association between
dietary energy density (DED) and the risk of type 2 diabetes. Materials and
Methods: In this matched nested case-control study, 178 new onset cases of
diabetes were selected from among participants of the Tehran Lipid and Glucose
Study, and followed for over 9 years. Each case was randomly matched with 3 controls
from among participants who had not developed diabetes. Dietary intakes were
determined using a valid and reliable food frequency questionnaire. DED was
calculated as energy intakes (kcal) from foods and beverages divided by the
weight (grams) of foods. Results: The mean ages of participants were
43±6.5 and 44.5±12 years, in women and men respectively. Individuals with
higher DED had higher calories, total fat, carbohydrate and processed meat
intakes and lower fruit and vegetable intakes in men and women (P<0.05).
Energy density was positively associated with incident diabetes in women, after
adjustment for diabetes risk factors and total calorie intake (OR: 2.28, P
trend=0.02) or total fat intake (OR: 2.15, P trend=0.03), an association which
was not significant in men. Conclusion: In this nested case-control
study, there was positive association between DED and risk of type 2 diabetes
in women. |
