Background: Awareness refers to a person ’scomprehension of a certain topic and realization that the topic is important for them. Lack of awareness of a balanced diet can lead to nutrient-related diseases, such as obesity, heart disease, diabetes, or iron deficiency, resulting in excess or deficient diet intake. Data from 2022 states that more than 1 billion people worldwide suffer from obesity, including 650 million adults, 340 million adolescents, and 39 million children.Objectives: This study aimed to identify demographic factors (sex, age, education level, and income level) associated with nutritional awareness. Research.Methods: A cross-sectional online survey using accidental sampling of 581 respondents aged 15–70 years was conducted in Kediri between March 4 and 14, 2025. The survey collected respondents’ sociodemographic attributes and nutritional awareness. Spearman and Chi Square test were performed to asses correlation between variables using SPSS version 26 for MacOS.Results: Some sociodemographic attributes were significantly correlated with dietary awareness (age, p < 0.000, r = 0.207; income, p = 0.000, r = 0.162; and sex, p = 0.000, r = 0.252) but not with nutritional awareness (p values = 0.000, p-values = 0.000, p-values = 0.000); in contrast, the level of education was not correlated with nutritional awareness (p = 0.512).Conclusion: Some sociodemographic attributes (age, income, gender) correlate with nutritional awareness while education level has no relationship.
