ObjectivesTo investigate the relationship between dyslipidemia and obesity status among Viet-namese adolescents.MethodsIn this case-control study, 282 adolescents (6–11 years), including 88 obese cases and 194 normal-weight controls, were recruited from a population-based cross-sectional study from two provinces in Vietnam. The anthropometric, blood lipid, and other laboratory test results of the study subjects were analyzed.ResultsObese children tended to have more visceral fat (Pearson’s r = 0.795, p < 0.0001) than subcutaneous fat (Pearson’s r = 0.754, p < 0.0001), and this difference was associated with an increase in blood triglyceride level (Pearson’s r = 0.232, p < 0.05) and a strikingly high rate of hypertriglyceridemia (38.6%). We also found that birth weight and parental body mass index were related to the status of obesity among the study subjects. However, only birth weight was significantly higher in the obese group than in the normal weight group. These findings indicate the effect of prenatal nutrition on childhood obesity. Furthermore, high-birth weight children had a surprisingly high rate of obesity.ConclusionTogether, our data suggest that obesity increased the risk for hypertriglyceridemia, which was, at least partially, due to prenatal nutrition.
During the American war in Vietnam, huge quantities of the highly toxic herbicide dioxin ('Agent Orange'), were sprayed over large areas of central and south Vietnam. In addition to polluting the environment and causing cancers and other diseases in those directly exposed to it, dioxin has caused high rates of pregnancy loss, congenital birth defects and other health problems in their children. This paper reports the findings of a pilot study in the year 2000 among 30 Vietnamese women whose husbands and/or who themselves were exposed to Agent Orange. The aim was to develop research in order to explore the impact of chemical warfare on people's lives. Using the reproductive lifeline and semi-structured interviews, information was gathered on both partners' periods of exposure to Agent Orange, pregnancy outcomes, perceived health problems of children and experiences of living with handicapped children. The women had had a high number of miscarriages and premature births. About two-thirds of their children had congenital malformations or developed disabilities within the first years of life. Most of the families were poor, aggravated by impaired health in the men, the burden of caring for disabled children, and feelings of guilt and inferiority. The plight of 'Agent Orange families' is special and should be placed in its historical and political context.
The study suggested the significant association of delivery method, birth weight, night sleep duration, and BDNF Val66Met polymorphism, with obesity in Vietnamese primary school children.
BackgroundThe dyslipidemia associated with obesity plays a major role in the development of atherosclerosis and cardiovascular disease. Dyslipidemia in childhood can progress in adult stage. APOE is one of the most important genes that regulate plasma lipid transport and clearance. The study aimed to assess whether the common APOE polymorphism is associated with lipid profiles and dyslipidemia, and it could be modulated by obesity-related traits (body mass index, waist circumference, hip circumference, and waist-to-hip ratio) in Vietnamese children.MethodsA case-control study was designed including 249 cases with dyslipidemia and 600 controls without dyslipidemia. Dyslipidemia is defined as elevated total or low-density lipoprotein (LDL) cholesterol levels, or low levels of high-density lipoprotein (HDL) cholesterol. Genotype for APOE polymorphism (rs7412 and rs429358) was determined by the polymerase chain reaction and restriction fragment length polymorphism method. The association of APOE genotypes with plasma lipid disorders was tested by binary logistic regression analysis, taking into account the confounding factors of age, sex, residence, province and obesity-related traits.ResultsIn comparison with ε3/ε3 carriers, the ε4 carriers had the highest concentration of serum TC and LDL-C in cases and controls (P ≤ 0.001), while ε2 carriers had the lowest. Carriers without TT haplotype had higher serum TC than those with TT haplotype. The ε4 carriers had higher hypoalphalipoproteinemia risk than ε3/ε3 carriers (OR = 2.78, P = 0.02) before and after adjustment for age, gender, residence and obesity-related traits.ConclusionsThe study suggested that the APOE genotype and haplotype significantly associated with plasma TC and LDL-C level in Vietnamese children. The association of APOE genotype with hypoalphalipoproteinemia was independent of obesity-related traits.Electronic supplementary materialThe online version of this article (doi:10.1186/s12944-016-0349-6) contains supplementary material, which is available to authorized users.
