    Background/Objectives: Sarcopenic obesity (SO), the coexistence of sarcopenia and obesity, poses serious health risks, such as increased mortality. Despite its clinical significance, key predictors of SO remain unclear, especially in severe obesity. This study aimed to identify independent predictors of SO in Italian older adults with obesity using a deep learning neural network. Methods: A cross-sectional study was conducted with hospitalized older adults diagnosed with severe obesity. SO was defined according to the 2022 ESPEN/EASO Statement Criteria, based on skeletal muscle function assessed by the five-repetition sit-to-stand test (5-SST) and body composition parameters evaluated using Dual X-ray Absorptiometry. A total of 42 independent variables were analyzed. Data normalization was performed using MinMaxScaler, and an optimal neural network architecture was selected via grid search with stratified 5-fold cross-validation. Model performance was assessed using accuracy, precision, recall, F1-score, AUC-ROC, and AUPRC metrics. Results: The correlation analysis revealed strong negative associations between SO and handgrip strength (HGS) (r = -0.785) and appendicular lean mass (ALM) (r = -0.745), as well as moderate correlations with 5-SST (r = 0.603), 30-second chair stand test (r = -0.474), 6-minute walking test (6m-WT) (r = 0.289), and waist circumference (WC) (r = 0.127). The deep learning model achieved an average classification accuracy of 72%, with a precision of 83% and an AUC of 0.9333. Conclusions: The main key predictors of SO were HGS, ALM, 5-SST, 30s-SST, 6m-WT, and WC in the early detection of this condition. The findings highlight deep learning's potential to improve SO diagnosis, risk assessment, clinical decision-making, and prevention in severely obese older adults.

    The aim of this study was to cross-sectionally investigate the relationships between obesity and spinal posture as well as mobility by comparing the spinal parameters between adults with obesity and normal-weight individuals. The spinal parameters were measured in 71 adults with obesity and 142 normal-weight individuals using a radiation-free back scan, the Idiag M360. Differences in spinal posture and movements between the two groups were determined using a two-way analysis of variance. Adults with obesity had greater thoracic kyphosis [difference between groups (Δ) = 6.1°, 95% CI 3.3°-8.9°, p < 0.0001] and thoracic lateral flexion (Δ = 14.5°, 95% CI 5.1°-23.8°, p = 0.002), as well as smaller thoracic flexion (Δ = 3.5°, 95% CI 0.2°-6.9°, p = 0.03), thoracic extension (Δ = 4.1°, 95% CI 1.1°-7.1°, p = 0.008), lumbar flexion (Δ = 10.4°, 95% CI 7.7°-13.5°, p < 0.0001), lumbar extension (Δ = 4.8°, 95% CI 2.2°-7.4°, p = 0.0003) and lumbar lateral flexion (Δ = 12.8°, 95% CI 9.8°-15.7°, p = < 0.0001) compared to those with normal weight. These findings provide relevant information about the characteristics of the spine in adults with obesity to be taken into careful consideration in the prescription of adapted physical activities within integrated multidisciplinary pathways of metabolic rehabilitation.

    Background: Anorexia nervosa is an eating disorder characterised by distorted eating behaviour, physical and mental health problems, and the highest mortality rate among psychiatric disorders. Although anorexia nervosa appears to be associated with alterations in the spine, studies investigating the characteristics of spinal postures and mobility in individuals with anorexia nervosa are scarce to date. The present study aims to examine the relationship between anorexia nervosa and spinal posture and mobility by comparing people with anorexia nervosa to age-matched, normal-weight controls. Methods: Spinal posture and mobility were evaluated using a radiation-free back scan, the Idiag M360 (Idiag, Fehraltorf, Switzerland). Between-group differences were assessed using a two-way analysis of variance. Results: Adult females suffering from anorexia nervosa exhibited reduced lumbar [difference between groups (Δ) = 10.5°, 95% CI 4.6°-16.5°, p < 0.001] and thoracic (Δ = 8.8°, 95% CI 2.4°-15.2°, p = 0.007) curvatures compared to normal-weight controls. The only difference observed in spinal movements between the two groups was thoracic flexion, which was greater in individuals with anorexia nervosa (Δ = 8.4°, 95% CI 2.1°-14.4°, p = 0.009). Conclusions: These findings emphasise the need to consider spinal posture and thoracic mobility in the musculoskeletal assessment of anorexia nervosa. Interventions aimed at improving spinal postures may help to develop effective rehabilitative strategies for addressing spinal problems associated with anorexia nervosa and thus contributing to counteract the possible further worsening with advancing age.

    Background: Profound musculoskeletal alterations encompassing bones and soft tissues are common in people with anorexia nervosa (AN). This study aims to examine spinal posture and mobility in adolescents with AN, and to compare these outcomes with those obtained from normal-weight female controls. Methods: Spinal posture and movements were measured in 37 adolescents with AN and 31 normal-weight controls using the Idiag M360 scan tool, and between-group differences were analyzed using analysis of covariance. Results: Spinal postures and the lumbar-to-hip ratio were not different between subgroups. By contrast, AN had reduced thoracic (-21.8 degrees, p < 0.0001) and lumbar (-18.2 degrees, p < 0.0001) mobility in the frontal plane, as well as decreased hip flexion (-14 degrees, p = 0.001) and extension (-18.6 degrees, p < 0.0001) compared to the CG. Conclusions: Thoracic and lumbar spinal mobility, mainly in the frontal plane, and also hip mobility in the sagittal plane, are decreased in AN. These findings provide clinically relevant insights into spinal characteristics in adolescents with AN.
