Awareness, knowledge, and behaviors regarding trans unsaturated fatty acids in a sample of Lebanese adults

Lebanon is a country in the Middle East that had been witnessing nutrition transition to a westernized diet high in trans fats (TFs) and saturated fatty acids (TFAs) that had been linked to cardiovascular diseases and many other health issues. This study examines TF-related awareness, knowledge, and self-reported behaviors among a sample of Lebanese adults aged between 18 and 64 years, as well as their association with sociodemographic factors and anthropometric measurements. Using a multicomponent questionnaire, a cross-sectional study was conducted online, across all Lebanese regions based on a convenience sampling method (n = 401). Factors associated with TF-related awareness, knowledge, and behaviors were examined by multivariate linear regression analysis. The study highlighted specific gaps in TF-related awareness, knowledge, and behavioral practices as well as differences by sociodemographic factors. Most of the participants (36%) had heard of partly hydrogenated oils (PHOs) rather than TFs (49%). A higher proportion of respondents (54%) said they understood a little about TFs, the majority had inadequate knowledge about the foods that contain TFs, and 44% said they would not give up eating their favorite snack even if they knew it contains TFs. Overall, consumers' awareness and knowledge about TFs are rather low and the majority had fair behavioral practices. In addition, being a woman and having higher education level were significantly associated with higher levels of TFs awareness, knowledge, and behavior scores. Higher behavior scores were shown in older participants, married, and those who had part-time jobs, whereas having higher income and normal weight were significantly associated with higher awareness scores. These findings offer valuable insight into TF-related awareness, knowledge, and behaviors in a sample of Lebanese adults and provide key information that could spur the development of evidence-based TFs reduction interventions specific to the Middle East.
