Background Overweight and obesity is a severe global health issue in both developed and developing nations. This study aims to estimate the national prevalence of overweight and obesity among school-aged children in Vietnam. Method We conducted a national cross-sectional study on 2788 children aged from 11-14 years old from September to November 2018. We applied the WHO 2007 and IOTF criteria to estimate the prevalence of overweight and obesity among participants. Poison regression analysis with cluster sampling adjustment was employed to assess associated factors with obesity and overweight. Metadata on sociodemographic characteristics, physical measurements, and lifestyle behaviors were also extracted to investigate these factors in association with overweight and obesity prevalence. Results The prevalences of overweight and obesity in Vietnamese children were 17.4% and 8.6%, respectively by WHO Z-score criteria, and 17.1% and 5.4%, according to the IOTF reference. Using WHO Z-score yielded a higher prevalence of obesity than the IOTF and CDC criteria of all ages and both sexes. The proportions of overweight and obesity were substantially higher among boys than girls across ages. Parental BMI was shown to be a significant factor associated with overweight/obesity status in both girls and boys. Only for boys, age (PR = 0.83, 95% CI 0.76-0.90) and belonging to ethnic minorities (PR = 0.43, 95% CI 0.24-0.76) were significant risk factors for overweight/obesity.
Aims: To evaluate the nutritional status of patients before thyroid surgery at the Thyroid Surgery Department, National Hospital of Endocrinology in 2022.
Methods: This was a cross-sectional study on 163 patients before thyroid surgery. Nutritional status of the patients was investigated using body mass index (BMI), mid-upper arm circumference (MUAC), and subjective global assessment (SGA).
Results: The rates of malnutrition according to SGA and BMI were 31.3 and 7.4%, respectively. The rate of overweight according to BMI was 10.4%. The rate of obesity was 1.8% according to BMI, while it was 0% by MUAC classification.
Conclusion: High rate of malnutrition was presented in the patients before thyroid surgery. It is important to use SGA to evaluate the patients and give an approptiate intervention of nutrition to prevent severe effects of malnutrition on surgical patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
