###### Abstract  
This cross-sectional study investigated interactions among sugar-related dietary patterns (DPs), personality traits, and cognitive-behavioural and emotional functioning. The study involved working-age women aged 18-54. Data were collected between Winter and Spring of 2020/21. The survey was conducted using anonymised questionnaires. The ten-item personality inventory (TIP-PL) was used to examine personality traits based on the Big Five personality trait model. A three-factor eating questionnaire (TFEQ-13) was used to measure the following eating behaviours: cognitive restraint (CR), uncontrolled eating (UE), and emotional eating (EE). The KomPAN questionnaire collected the frequency of the intake. Dietary patterns (DPs) were derived by principal component analysis (PCA). A logistic regression (OR) was applied to verify the associations among the DPs, personality traits, and cognitive-behavioural and emotional functioning. Three DPs were identified: sweet-Western (SWDP), pro-healthy (PHDP), and dairy (DDP). Women with high conscientiousness were less likely, by 33%, to adhere to the upper tercile of the SWDP and 80% more likely to the upper tercile of the PHDP. Elevated CR intensity increased by almost twofold (OR: 1.93; \(p<0.001\)) the likelihood of high adherence to the SWDP. The high intensity in the EE decreased by 37% (OR: 0.63; \(p<0.01\)) the likelihood of increased adherence to the SWDP. Personality traits and eating behaviours significantly correlated with the extracted SWDP. s +

fruits, vegetables, dairy, or meat-originating foods. Dietary behaviour has increasingly been attributed to personality types and other psychological factors [11; 12; 13]. Psychodietetics is gaining more popularity. However, despite the growing interest in the relationship between the diet and mental health, the literature has not paid attention to possible relationships among sugar intake, personality traits, and cognitive-behaviour or emotional functioning. It is essential to learn about these mechanisms. In health psychology, many studies confirm that an individual's personal resources and personality traits are essential for engaging in healthy behaviour [14]. And critical roles are played by stress-type personalities, the surrounding emotions, a sense of coherence, and self-efficacy [15; 16]. Other studies emphasise the importance of an internal locus of control, emotional maturity, resilience to stress, autonomy, low levels of anxiety and fear, and high self-esteem [17; 18]. Some researchers recognise that conscientiousness and agreeableness are associated with health-promoting behaviours, while neuroticism is associated with behaviours that harm health [19]. The critical mechanism underlying such relationships is the generation of positive affective states by conscientiousness and agreeableness and the generation of negative affective states by neuroticism [19]. The positive emotions that constitute the principal mechanism conducive for engaging in health-promoting eating behaviours promote health. Findings from other studies indicate the link among sugar consumption, the human brain, and human behaviour [7]. A link has been discovered between eating a diet rich in sugar and the occurrence of emotional disorders, such as anxiety and depression [11]. Some sources report that personality traits, such as neuroticism, extroversion, and conscientiousness, can influence preferences for sweet tastes [12]. Studies have shown that personality traits can, indeed, affect dietary choices, including the type of diet [13]. Individuals marked by neuroticism and alexithymia were likelier to have a low consumption of fruits and vegetables and an increased consumption of sugar and saturated fats [13]. Subjects characterised by neuroticism and extroversion consumed sweeter and saltier foods than people with conscientiousness characteristics [12].
