Introduction: We aimed to study determine the ideal body mass index (BMI) range for optimal strength, functionality, physical performance, nutrition and quality of life.
Methods: We designed a retrospective cross-sectional study and included older outpatients admitted between November 2012-December 2021. We noted the patients’ demographic characteristics, number of comorbid diseases, number of drugs, falls and BMI. Functional status was evaluated with Lawton-instrumental-activities-of-daily-living (IADL). Nutritional assessment was performed by Mini-Nutritional-Assessment (MNA) test. Timed Up and Go test (TUG), gait speed test(UGS), EuroQol-5 Dimensio (EQ-5D) and handgrip strength (HGS) measurement were extracted from patient records. We performed ROC analyses to determine the optimal body index for the study parameters.
Results: We included 1789 participants. The mean age of the cases was 74.8 ± 7.1, and 68.3% of the cases were women. Optimum BMI was between 28–29 kg/m2 for the sake of preserved muscle strength, physical performance, functionality, normal nutrition and better quality of life (HGS: 28.4 kg/m2 [AUC(95%): 0.66, p: 0.00 senstivity (Se) (%): 60.8, specificity (Sp) (%): 60.4], UGS: 29.2 kg/m2 [AUC(95%): 0.60, p:0.00 Se (%): 51.0, Sp(%): 48.4], TUG: 29.9 kg/m2 [AUC(95%): 0.36, p: 0.00 Se (%): 52.5, Sp(%): 48.6], IADL: 29.0 kg/m2 [AUC(95%): 0.60, p:0.00 Se (%): 56.3, Sp(%): 53.7], MNA: 28.3 kg/m2 [AUC(95%): 0.65, p:0.00 Se (%): 64.6, Sp(%): 64.6], EQ-5D: 29.0 kg/m2 [AUC(95%): 0.57, p:0.01 Se (%): 58.5, Sp(%): 56.6]).
Key conclusions: The optimal BMI in older outpatients has been detected as 28–29 kg/m2. Further longitudinal studies will have the potential to establish the possible cause-effect relationship.
