Abstract

Background and aims: We investigated the association of dietary intake, particularly fat and its constituent fatty acids, with atherogenic indices in adult patients with overweight, obesity and/or type 2 diabetes (T2D). Material and Methods: Two hundred eighty-five outpatients were selected in two cities located in the Northwestern region of Algeria. Anthropometric measurements for body weight, height, body mass index (BMI) and waist circumference were performed. Relationships between dietary intakes, estimated by a 3- days food record, and fasting blood atherogenic indices - total cholesterol-to-high-density lipoprotein cholesterol ratio (TC/HDL-c) and apolipoprotein (apo) B-to-apo A1 ratio, were analysed. Results: Study group included 58.59% overweight/obese T2D patients, 24.91% normal weight T2D patients and 16.49 % overweight/obese patients without diabetes. Higher dietary consumption (p= 0.003) of total fat, saturated fatty acids (SFAs) and polyunsaturated fatty acids (PUFAs), was recorded in the group of overweight/obese T2D patients. Significant positive correlations were observed between apo B/apo A1 and total fat (p= 0.035), total SFAs (p= 0.042) and palmitic acid (p= 0.042) in the group of overweight/obese T2D patients and with ω6 fatty acid (p= 0.030) in the group of overweight/obese patients without diabetes. In the two groups of T2D patients, whether normal weight, overweight/obese, numerous positive correlations with TC/HDL-c were disclosed for PUFAs, ω6 and fatty acids ratios, namely, ω6/ω3, monounsaturated fatty acids (MUFA)/SFAs and (MUFAs+PUFAs)/SFAs. Conclusion: Most adults, whom are either affected by an excess weight or T2D or both together, are prone to cardiovascular risk. Dietary intakes, particularly in fat and its constituent fatty acids, have an important effect on blood lipid atherogenic indices (TC/HDL-c and apo B/apo A1 ratios).
