Congratulations to Dr Karim Khaled on the recent publication of the article ‘The Association between Psychological Stress and Dietary Quality and Patterns among Women of Childbearing Age in Lebanon‘.

The paper focuses on psychological stress linked to poorer dietary quality can lead to serious diseases. The objective of this study was to examine the association between psychological stress and dietary quality/patterns among childbearing-aged women in Lebanon. Female participants (n = 249) participated in an online survey-questionnaire which included the previously adapted European Prospective into Cancer and Nutrition food frequency questionnaire and stress, depression, anxiety, physical activity, adiposity, and socio-demographic questions.

The a-priori dietary quality was assessed through the Mediterranean Diet (MD) index. The a-posteriori latent dietary-patterns (DPs) were derived through factor analysis. Regression analysis was performed to investigate the predictors of the DPs. Participants mainly had a medium MD adherence (61%). No association was found between stress and MD adherence. Factor analysis revealed four DPs: “potatoes, vegetables, legumes, soups and sauces, and non-alcoholic beverages” (DP1), “cereals, fats and oils, milk and dairy products, and sugars and snacks” (DP2), “alcoholic beverages, fish and seafood, eggs, and meats and meat products” (DP3), and “fruits and nuts and seeds” (DP4). Regression analysis indicated that DP1 was positively associated with monthly income (p = 0.02) and negatively with mother’s educational level (p = 0.03). DP2 was negatively associated with father’s employment status (p = 0.01) and marital status (p = 0.008). DP3 was negatively associated with higher father’s educational level (p = 0.018), but positively with BMI (p < 0.001). DP4 was positively linked with BMI (p = 0.01).

Further studies are needed to investigate the association between psychological stress and dietary quality/patterns among Lebanese childbearing aged women.
