Abstract

Overweight and obesity (OW–OB) among Vietnamese men are increasing and associated with early metabolic disturbances. National reports and the World Health Organization indicate that during 2020–2025, the prevalence of OW–OB has risen more rapidly than before due to changes in lifestyle, reduced physical activity and post-COVID-19 effects. Therefore, analysing data collected before 2020 helps clarify baseline metabolic risks in this population. Objective: To describe anthropometric characteristics, nutritional status and metabolic disorders among OW–OB men in the 2016–2017 dataset, and to compare with national nutritional epidemiology trends during 2015–2025. Methods: A cross-sectional study was conducted on men aged ≥18 years, BMI ≥23 kg/m² in Hanoi (2016–2017). Anthropometric indicators (waist circumference, WHR), fasting glucose, 2-hour post-OGTT glucose, blood lipids and abdominal obesity were descriptively analysed and compared with national evidence. Results: Most participants presented central obesity with elevated waist circumference and WHR above diagnostic thresholds. Blood glucose and lipid abnormalities were common, particularly impaired glucose tolerance and elevated triglycerides. The metabolic pattern was consistent with findings reported by the National Hospital of Endocrinology in the period 2015–2025. Conclusion: Data from 2016–2017 show that OW–OB men already had high metabolic risk prior to the accelerated increase in obesity during 2020–2025. Early nutritional and lifestyle interventions are therefore needed to limit the progression of metabolic disorders.
