Effects of dietetic WHO's recommendations on HDL-C level in a Tunisian obese group

Objective. - Evaluate the effect of dietetic WHO's recommendations on hypoHDLemia in obese Tunisians volunteers. Methods. - We enrolled 93 volunteers hospital personal. Anthropometric parameters, blood pressure, lipids levels, glycemia and insulinemia were measured. Dietary intake assessment was undertaken, results were transformed into dichotomic variables according to the respect or not of the WHO's recommendations for chronic diseases prevention. Health Diet Index (HDI) was calculated. Results. - After adjustment for potential confounders factors, we found significant reduction of hypoHDLemia risk by respect of the dietetic WHO's recommendations for the saturated fatty acids (OR = 0.602; P = 0.033), monounsaturated fatty acids (OR = 0.765; P = 0.038), fish consumption (OR = 0.633; P = 0.049) free sugar (OR = 0.759; P = 0.041). OR of hypoHDLemia associated with a HDI greater than or equal to 4 was 0.218; P = 0.048. These same recommendations have significant effect to reduce high TC/HDL-C. In addition PUFA [6-10%], total carbohydrates [55-75%] and increased fruits and vegetables protect against high TC/HDL-C. Conclusion. - Several dietetic WHO's recommendations seem to prevent hypoHDLemia. The association of at least four recommendations had a significant beneficial effect. (C) 2012 Elsevier Masson SAS.
