Abstract
The rapid transformation of global lifestyles, particularly among university students, has intensified concerns regarding the interplay between stress, dietary habits, and physical activity and their cumulative impact on psychological well-being. This study presents a comprehensive, theory-driven exploration of the lifestyle triad-stress levels, dietary patterns, and exercise behaviors-within the broader framework of noncommunicable disease prevention and mental health promotion. Drawing upon interdisciplinary literature, including epidemiological data, psychological theories, and global health policy frameworks, this research aims to elucidate the complex interrelationships that define student well-being.
The study synthesizes findings from diverse sources to examine how academic stress, lifestyle behaviors, and psychological constructs such as self-efficacy and coping mechanisms interact to influence mental health outcomes. Particular attention is given to the prevalence of stress and depression among university populations, as well as the role of lifestyle factors in modulating these conditions. The analysis is grounded in established theoretical models, including self-determination theory and social cognitive theory, which provide a conceptual basis for understanding behavior regulation and well-being.
Results indicate a strong association between high stress levels and poor dietary and exercise habits, which collectively contribute to diminished psychological well-being. Conversely, students who engage in regular physical activity and maintain balanced diets exhibit greater resilience and lower anxiety and depression. The study also highlights the of institutional and policy-level interventions in promoting healthy lifestyles, in alignment with global initiatives such as the Sustainable Development Goals and the Shanghai Declaration on Health Promotion.
The discussion addresses methodological limitations, including variability in measurement and cultural differences, and proposes directions for future research. Overall, this study contributes a nuanced and integrative perspective on student well-being, emphasizing the of holistic approaches to health promotion in academic settings.
