Abstract:
Objective:To explore the correlation between normalized grip strength (NGS) and normal weight obesity (NWO) in the population undergoing health check-ups.Methods:It was a cross-sectional study. A cluster sampling method was adopted to consecutively select 4 104 subjects who completed general health check-ups, body composition tests, and grip strength tests at the Medical Examination Center of Peking University Third Hospital from January 2019 to December 2023. The general information, physical examination results, biochemical indicators, body composition, and grip strength test results were collected. The subjects were grouped by gender and whether they had NWO (male: NWO group 314 cases, normal control group 690 cases; female: NWO group 834 cases, normal control group 2 266 cases). The differences in various indicators between the NWO group and the normal control group were compared by using t-tests, χ 2 tests, or Mann-Whitney U tests. The subjects were divided into four groups with the quartiles of NGS (Q 1-Q 4 groups), and binary logistic regression analysis was used to explore the correlation between the NGS and NWO. The receiver operating characteristic (ROC) curve was used to evaluate the optimal cut-off point of the NGS for diagnosing NWO. Results:Among the 4 104 subjects included in the analysis, 1 148 (28.0%) had NWO. The risk of NWO in both males and females increased with the decrease of NGS. Compared with the Q 4 group, the risk of NWO in the Q 2 and Q 1 groups of males increased by 2.600 times ( OR=2.600, 95% CI:1.556-4.343) and 4.350 times ( OR=4.350, 95% CI: 2.618-7.229), respectively; the risk of NWO in the Q 3, Q 2, and Q 1 groups of females increased by 2.024 times ( OR=2.024, 95% CI: 1.322-3.099), 4.265 times ( OR=4.265, 95% CI: 2.856-6.371), and 7.395 times ( OR=7.395, 95% CI: 4.991-10.956), respectively (all P<0.05). The optimal cut-off point of the NGS for diagnosing NWO in males and females was 0.636 2 and 0.472 2, respectively. Conclusions:The NGS is negatively correlated with the risk of NWO. Evaluation of the NGS can provide a reference for the early diagnosis and prevention of NWO.
