Background <p>There is increasing concern regarding the effects of contemporary lifestyles on spinal health. This study aimed to evaluate recent trends in cervical lordosis (CL) curvature over the past eight years.</p> Methods <p>Asymptomatic individuals who underwent cervical spine radiography at four hospitals were randomly selected from hospital databases for a comparative analysis of data spanning from 2016 to 2024. The curvature of CL was assessed using three methods: the C2-C7 Cobb angle (Cobb A), the C2-C7 Harrison posterior tangent angle (Harrison A), and Borden’s method for evaluating CL depth. Measurements of CL curvature were performed using the previously described methodologies by two authors, employing a Picture Archiving and Communication System. The selected participants were categorized into two cohorts: young adults (aged &lt; 40 years) and older adults (aged ≥ 40 years).</p> Results <p>In the 2016 and 2024 cohorts, no significant age differences based on gender were observed. Females in these cohorts exhibited significantly lower CL curvature measurements, as assessed by the Cobb A and CL depth indices, in comparison to their male counterparts. Furthermore, within these cohorts, older adults demonstrated a reduction in CL depth compared to younger adults. The assessment of CL curvature in the 2024 cohort, utilizing the Cobb A and Harrison A methods, revealed a reduction in measurements compared to the 2016 cohort. This decrease was observed across both genders and all age groups.</p> Conclusions <p>The findings of this study indicate a decline in CL curvature over the past eight years. Further investigation is warranted to understand the etiology and clinical significance of this observed trend.</p>
