Özet (Çeviri)

A cross-sectional study was conducted in order to evaluate the omega-3 fatty acids (n-3 FAs) intake, omega-3 index (n-3 index) and to examine the association between the dietary intake of n3 FAs with n-3 index in selected groups of smokers, overweight and obese Jordanian adults and normal-weight controls. A total of one hundred and fifty Jordanian adults (19-45 years old) from both genders was recruited from a private clinic and divided into four groups, where the ratio of healthy control group to the other selected groups was 2:1. A three-day food record was used to evaluate the dietary intake of n-3 FAs among participants. Total FAs in red blood cells (RBCs) was determined using gas chromatography (GC). N-3 index was determined by measuring the sum of Eicosapentaenoic (EPA) and Docosahexaenoic acid (DHA) in the membranes of RBC expressed as the percentage of total FAs. N-3 index is considered as a potential risk factor for coronary heart disease (CHD) mortality, especially sudden cardiac death. Results of the current study indicated that normal-weight participants had significantly (p < 0.05) the highest n-3 index (4.27%±0.21), while the lowest n-3 index was among smoker participants (1.82%±0.25). Moreover, overweight and obese participants had significantly (p < 0.05) higher dietary intake of n-3 FAs (0.71g±0.07 and 0.69g ±0.07, respectively) than normal-weight and smoker participants (0.44 g±0.05 and 0.34 g±0.04, respectively), as a result of consuming higher total calories and higher amounts of total fats. Furthermore, among different participants no significant (p ≥ 0.05) association was found between n-3 index and alpha linolenic acid (ALA), EPA, DHA or total n-3 FAs intake. xii As a conclusion, normal-weight participants had the highest n-3 index. Despite the fact that overweight and obese participants had higher n-3 FAs intake than other participants, their n-3 index was lower than that in normal-weight and smoker participants. Thus, overweight and obesity had a strong effect on n-3 index. The n-3 index values obtained for different participants indicated that most participants lie within the high risk level (<4%). This makes them highly susceptible to CHD and sudden cardiac death (as well as other health complications)
