Associations Between Lifestyle, Habits, Quality of Life and Non-Carious Diseases: A Scoping Review

This scoping review aimed to map and synthesize the scientific evidence on how lifestyle factors and quality of life are associated with the onset and progression of non-carious diseases (NCDs) in young and adult populations, identifying patterns, methodological characteristics, and gaps in the existing literature. A systematic literature search was conducted across PubMed, Embase, Scopus, and Web of Science databases to retrieve studies evaluating the influence of lifestyle habits and quality of life indicators on NCDs development and worsening. Most included studies were conducted in Brazil, with cross-sectional designs being the most prevalent. The main modulating factors identified included gastroesophageal reflux, post-bariatric conditions, smoking, bruxism, and anxiety. The results were summarized through a descriptive narrative synthesis. Considerable methodological heterogeneity was observed, particularly due to the absence of standardized protocols for NCDs assessment. Methodological quality was also evaluated to contextualize the robustness of the available evidence. Overall, lifestyle and quality of life factors play an important role in the progression of NCDs, underscoring the need for their integration into diagnostic and therapeutic planning. Further clinical studies are warranted to deepen the understanding of the relationship between NCDs and broader health domains, with particular attention to early oral aging syndrome (EOAS).
