Background: Hypertension (HTN) significantly contributes to global disease burden, and its prevalence varies amongst different countries and regions. This work is aimed to characterize the hypertensive prevalence and identify risk factors for HTN among the residents in five locations (four communes and one town) of Moc Chau district (Son La province, Vietnam). Methods: A cross-sectional study with a cross-sectional methodology was done in selected places from August 2018 to December 2018. We interviewed 197 participants aged equal to or more than 18 years old and measured their blood pressure (BP). Univariate and multivariate logistic regression were applied. Results: The overall HTN prevalence of 30.0% was recorded. The differences of HTN prevalence rates were seen by several characters including age groups (p <0.001), accompanying disease (p <0.001) and alcohol drinking (p <0.05). Factors independently associated with hypertension were age (

Caring for children and mothers suffering from cardiac disease is highly challenging, with issues including late diagnosis as well as inadequate infrastructure and supply of drugs. We aimed to evaluate maternal outcomes among pregnant women suffering from heart disease with a live birth, and explored the risk factors for fetal growth restriction among these patients. A retrospective study was performed at the National Hospital of Obstetrics and Gynecology (Hanoi, Vietnam) over a 3-year period from 2014 to 2016. A total of 284 patients were enrolled in the study. Overall, most women were aged below 35 years and were diagnosed with heart disease before pregnancy. Of the women experiencing rheumatic heart disease, the prevalence of mitral valve regurgitation was the highest (40.14%), while the figure for aortic valve regurgitation was the lowest (4.23%). Of women with congenital heart defects, the most common defects were ventricular septal defect (VSD) and atrial septal defect (ASD) (19.37% and 16.55%, respectively), while 5.28% of mothers were diagnosed with tetralogy of Fallot and 1.76% with patent ductus arteriosus. Noted clinical presentations of the patients included palpitation (63.38%), breathlessness (23.59%), leg edema (8.45%), and chest pain (8.1%). The common complications in the study population included 16.90% of women having heart failure and 19.37% having arrhythmias. The incidence of fetal growth restriction was 9.15%. Hypertension (odds ratio (OR): 59.75, 95% confidence interval (CI): 9.1–392.17), the heart disease types (ASD (OR: 4.27, 95% CI: 1.19–15.29) and tetralogy of Fallot (OR: 6.82, 95% CI: 1.21–38.55)), and the complications (heart failure (OR: 10.34, 95% CI: 2.75–38.87) and pulmonary edema (OR: 107.16, 95% CI: 4.96–2313.93)) were observed as risk factors for intrauterine growth restriction. This study provides a cornerstone to promote further studies and to motivate people to apply evidence-based medical care for mothers with diagnosed cardiac disease in the antenatal and postnatal periods.

Background The aims were to characterize the prevalence of hypertension (HTN) and explore its associations in the northern mountainous. Methods We carried out a cross-sectional study in two communes in Chiem Hoa district, Tuyen Quang province, between June and November 2017. All subjects at the age of 18 years and over currently living in two communes. The usage of the descriptive statistics was to characterize the HTN prevalence. We used the univariate and multivariate models of logistic regression to determine the prevalence and related factors of HTN. ResultsThere were 319 people with overall HTN in the total of 675 participants. Among people with HTN, there were 101 ones with isolated systolic hypertension (ISH). The proportion of HTN among the Tay ethnic group was 47.6%. The factors related to HTN included group, body mass index (BMI), low physical fitness, and waist-hip ratio (WHR). These factors as well as the ethnicity were significantly associated with ISH. Conclusions Two communes of Chiem Hoa district in Tuyen Quang province had a high prevalence of HTN. Age, BMI, WHR, and physical activity were the risk factors of overall HTN and ISH. In particular, ISH was affected by ethnicity.

Developmental defects of enamel (DDE) are induced and regulated by several factors including genetics and the environment. There is evidence showing that dioxin in polluted areas has a strong effect on the health and development of teeth. However, there has been no study on DDE in the dioxin-affected regions in Vietnam. To identify the effect of dioxin on the prevalence of DDE in studied areas in Vietnam, a cross-sectional study was conducted in 2200 adults in the A Luoi district in the Thua Thien Hue province (the dioxin-affected region) and in the Kim Bang district in the Ha Nam province (dioxin-unaffected region) in 2015. All subjects were interviewed using a structured questionnaire and their teeth were examined and scored for enamel defects based on the 1992 FDI criteria. The defected teeth were then photographed. Our results showed that the DDE rate in A Luoi was 20.5% when measured as mouth prevalence and 5.8% when measured as tooth prevalence, while the rates in Kim Bang were 10.4 and 2.32% for mouth and tooth prevalence, respectively. Demarcated opacities were predominated in both districts (45.5% in A Luoi and 52.2% in Kim Bang). The DDE rate of the anterior teeth group was higher than that of the posterior teeth group. Most lesions presented on the buccal surface of the tooth. Overall, the DDE prevalence in the dioxin-affected region was 2.2 times higher than that in non-dioxin-affected region in the studied regions in Vietnam.
