This paper evaluated the effectiveness of community-based nutrition and physical activity program to change physical activity, dietary behavior, glucose level, and some metabolic parameters among adults aged 50-65 with pre-diabetes after a six-month intervention. Participants who were pre-diabetics and had at least 2 components of Metabolic Syndrome (MetS) in Hanam province, Vietnam were randomly assigned into the intervention (n=44) and control (n=49) groups. The intervention group received a health promotion package, whereas the control received 1 session of standard advice during six months. Results showed that there were significant increases in the intervention group for physical activity outcomes, including moderate activity, walking time, total physical activity, and mean sitting time. A significant difference was also observed between intervention and control groups at post-test in walking time, total physical activity, and sitting time. For dietary behaviors, frequent use of salt was decreased significantly after 6 months for both groups while the intervention group's frequent intake of cooking oil was significantly reduced. Regarding fasting glucose level and other metabolic parameters after 6-month intervention, reduction in fasting glucose level were found in the intervention but increased in the control group. Significant improvement in HDL-C and diastolic blood pressure among the intervention in comparison to the control group was reported. A significant reduction in weight in the intervention group in comparison with the control group was also found after the 6-month intervention. This program successfully improved dietary behaviors and physical activity, fasting glucose level, and cardiovascular risk among adults with pre-diabetes in Vietnam.
Background:The aim of this study was to identify the prevalence of Metabolic Syndrome (MetS) and its components among overweight adults in a rural region Vietnam based on the International Diabetes Federation (IDF), 2005 and the Joint Interim Statement (JIS) 2009 definitions, and determine the level of agreement between these definitions. Methods: A sample of 1076 overweight adults aged 50-65 in 10 randomly selected communes in Phu Ly district, Hanam province, Vietnam were selected into the study. Study participants were collected fasting venous blood samples by certified phlebotomists. Anthropometric measures were also performed to obtain weight, height, waist circumference. MetS was defined using the IDF (2005), and the JIS ( 2009) definitions. The level of agreement between the two definitions was indicated by the sensitivity, specificity, and the Kappa index. Results: The prevalence of MetS among the overweight adults was 41.6%, and 44.0% based on the IDF (2005), and the JIS ( 2009) definition, respectively. The MetS prevalence among females was higher than that among males in the two definitions. The level of agreement between the two definitions was excellent (Kappa index = 0.987, p < 0.001). Conclusion:The JIS (2009) definition identified more Vietnamese overweight adults with MetS compared to the IDF (2005) criteria, 44.0%, and 41.6%, respectively. Females showed to be having higher prevalence in comparison to males regardless the definitions used. Excellent agreement between the two criteria was found.
Health literacy refers to the degree to which people can access and understand health information, as well as communicate their health needs to service providers. The scale has been standardized and divided into 3 groups: Health care, prevention of disease, health promotion. Children under 3 years have immature immunological system, which can affect their development in the future. However, the health management, diseases treatment, and diseases prevention of children younger than 3 years of age depend signifcantly on the health literacy of their mothers. This study aims to describe the health literacy of mothers who have children under 3 years and some factors affecting their health literacy. Data were collected on 389 mothers of children younger than 3 years who take their children to the vaccination clinics at Hanoi Medical University and latent analysis was conducted to identify class of health literacy within the sample. Three health literacy classes were identifed. The lowest mean health literacy index was within the disease prevention dimension, where the largest number of respondents showed limited health literacy. Three distinct health literacy level were identifed and termed low (n = 35.9%), moderate (n = 243, 62.5%) and high health literacy (n = 111, 28.5%). We found that higher scores of Health Literacy Scores (HLS) closely correlated with higher educational levels, the job of mothers, the age of children and the frequency of searching for health information using the internet. There were signifcant better overall scores in HLS among parents with higher education levels (university degree or higher with more than under high school graduated).
