Abstract
Abstract This study analyzed the difference between actual obesity level and subjectively perceived body-type in adults aged 20 years or older and investigated the difference in the amount of physical activity and health-related quality of life (HRQOL) for each difference between body mass index (BMI) and subjective body recognition (SBR). This study examined 21,326 adults regarding their BMI, subjectively perceived body-type, physical activity (according to International Physical Activity Questionnaire; IPAQ), and HRQOL (EuroQol-5 Dimension; EQ-5D) from the 7th Korea National Health and Nutrition Examination Survey (2014–2017). Independent t-test, analysis of variance (ANOVA), and chi-square test were conducted. High (Mean ± SD = 6.85 ± 25.20, p = .003) and moderate intensity of physical activity (Mean ± SD = 13.41 ± 30.01, p = .001) was higher in those with the same BMI and SBR than those who did not. In addition, those with normal BMI and SBR had the highest high (Mean ± SD = 7.20 ± 26.05, p < .001) and moderate intensity (Mean ± SD = 13.89 ± 30.18, p < .001). They had the highest percentage of responding as normal in the five EQ-5D sub-items. As the difference between the subjectively perceived body-types as well as normal range of BMI decreased, the amount of physical activity performed and positive results of HRQOL were confirmed. Various health promotion programs and policy recommendations to reduce the gap between subjective body perception and actual obesity are required.

- Pretraining has recently greatly promoted the development of natural language processing (NLP)
- We show that M6 outperforms the baselines in multimodal downstream tasks, and the large M6 with 10 parameters can reach a better performance
- We propose a method called M6 that is able to process information of multiple modalities and perform both single-modal and cross-modal understanding and generation
- The model is scaled to large model with 10 billion parameters with sophisticated deployment, and the 10 -parameter M6-large is the largest pretrained model in Chinese
- Experimental results show that our proposed M6 outperforms the baseline in a number of downstream tasks concerning both single modality and multiple modalities We will continue the pretraining of extremely large models by increasing data to explore the limit of its performance
