- Rationale: Health and demographic surveillance sites (HDSSs) are important sources for health planning and policy in many low and middle income countries. Almost all HDSSs are in rural settings. The article aims to present the experiences and some concrete results for the first three years of operation of an urban HDSS in Hanoi, Vietnam, and discuss advantages and disadvantages of conducting health studies in HDSSs. Design, population and sample size: The DodaLab urban HDSS was established in 2007 in three communes at different economic levels in Dong Da district, Hanoi, Vietnam. Demographic, social and economic information about 10,000 households and their 37,000 persons was obtained through household interviews. Quarterly follow-up was initiated to provide information about vital events, birth, death and migration. A new household survey was undertaken in 2009. The existing rural HDSS FilaBavi, started in 1999, with 12,000 households and 52,000 persons, was used as the blueprint. Conclusions: It was possible to establish and run an urban HDSS with experiences from the rural site. The urban and rural contexts are different and demographically, economically and socially complex, but the use of HDSSs can facilitate research beyond very simplified models for comparisons. General statements about external validity of results from the HDSS cannot be made. This issue has to be considered specifically in every situation as an integral part of the research so that the results can be made useful outside the researched HDSS and in performing relevant comparisons.

- The ICD-11 reconceptualized Posttraumatic Stress Disorder (PTSD) as a narrowly defined fear-based disorder, and introduced Complex PTSD (CPTSD) as a new diagnosis comprised of PTSD symptoms and symptoms of ‘Disturbances in Self-Organization’ (DSO) that are more reflective of general dysphoria. Previous research suggests that PTSD symptoms mediate the association between childhood trauma and physical health problems, including cardiovascular disease. No study has yet assessed how posttraumatic stress symptoms, as outlined in the ICD-11, influence the association between childhood trauma and somatic problems in adulthood.ObjectiveThis cross-sectional descriptive study examined whether PTSD and DSO symptoms mediated the associations between childhood physical and sexual abuse and childhood emotional abuse and neglect and somatic problems and cardiovascular diseases (CVD) load in adulthood.MethodsGeneral adult population samples from Ireland (N = 1020) and the United Kingdom (N = 1051) completed self-report questionnaires online.ResultsStructural equation modelling results indicated that PTSD and DSO symptoms fully mediated the association between both forms of childhood trauma and somatic problems, and that PTSD symptoms but not DSO symptoms fully mediated the association between childhood trauma and CVD load.ConclusionPsychological interventions that effectively treat CPTSD symptoms may have the added benefit of reducing risk of physical health problems.

- Abstract Background Differences between urban and rural settings can be seen as a very important example of gaps between groups in a population. The aim of this paper is to compare an urban and a rural area regarding child growth during the first two years of life as related to mother’s use of antenatal care (ANC), breastfeeding and reported symptoms of illness. Methods The studies were conducted in two Health and Demographic Surveillance Sites, one rural and one urban in Hanoi, Vietnam. Results We found that children in the urban area grow faster than those in the rural area. There were statistical associations between growth and the education of the mother as well as household resources. There were positive correlations between the number of ANC visits and child growth. We also saw a positive association between growth and early initiation (first hour of life) of breastfeeding but the reported duration of exclusive breastfeeding was not statistically significantly related to growth. Reporting symptoms of illness was negatively correlated to growth, i.e. morbidity is hampering growth. Conclusions All predictors of growth discussed in this article, ANC, breastfeeding and illness, are associated with social and economic conditions. To improve and maintain good conditions for child growth it is important to strengthen education of mothers and household resources particularly in the rural areas. Globalization and urbanization means obvious risks for increasing gaps not least between urban and rural areas. Improvement of the quality of programs for antenatal care, breastfeeding and integrated management of childhood illness are also needed in Vietnam.

- Background: Good infant growth is important for future health. Assessing growth is common in pediatric care all over the world, both at the population and individual level. There are few studies of birth weight and growth studies comparing urban and rural communities in Vietnam. The first aim is to describe and compare the birth weight distributions and physical growth (weight and length) of children during their first year in one rural and one urban area of Hanoi Vietnam. The second aim is to study associations between the anthropometric outcomes and indicators of the economic and educational situations. Methods: Totally 1,466 children, born from 1st March, 2009 to June 2010, were followed monthly from birth to 12 months of age in two Health and Demographic Surveillance Sites; one rural and one urban. In all, 14,199 measurements each of weight and length were made. Birth weight was recorded separately. Information about demographic conditions, education, occupation and economic conditions of persons and households was obtained from household surveys. Fractional Polynomial models and standard statistical methods were used for description and analysis. Results: Urban infants have higher birth weight and gain weight faster than rural infants. The mean birth weight for urban boys and girls were 3,298 grams and 3,203 grams as compared to 3,105 grams and 3,057 grams for rural children. At 90 days, the urban boys were estimated to be 4.1% heavier than rural boys. This difference increased to 7.2% at 360 days. The corresponding difference for girls was 3.4% and 10.5%. The differences for length were comparatively smaller. Both birth weight and growth were statistically significantly and positively associated with economic conditions and mother education. Conclusion: Birth weight was lower and the growth, weight and length, considerably slower in the rural area, for boys as well as for girls. The results support the hypothesis that the rather drastic differences in maternal education and economic conditions lead to poor nutrition for mothers and children in turn causing inferior birth weight and growth.

Endothelial injury in vivo: a technical and statistical approach to the study of aortic integrity.

- The endothelium can be a link connecting risk factors with the development of cardiovascular disease, and methods for studying endothelial integrity are therefore important. We describe a method of studying endothelial injury in vivo by combining immunohistochemistry with an improved technique of producing "enface" preparations (Häutchens) aortic endothelium of rabbits and guinea pigs. These Häutchens enabled the study of large numbers of endothelial cells and adherent cells (probably leukocytes) at different locations along the aorta. The statistical distributions of the number of injured endothelial cells and adherent cells in a visual field were also investigated, and both closely followed a log-normal distribution. Based on this distribution, a method to estimate endothelial injury by grouping the cell count data, instead of exact counting, was developed. The grouped cell count data were then used to calculate the grouped mean and grouped standard deviation for each animal. The improvements of the technical and statistical methods offer good opportunities to study various aspects of endothelial integrity in a time efficient manner.

- ABSTRACT: BACKGROUND: The use of antenatal care (ANC) varies between countries and in different settings within each country. Most previous studies of ANC in Vietnam have been cross-sectional, and conducted in rural areas before the year 2000. This study aims to compare the pattern and the adequacy of ANC used in rural and urban Vietnam following two cohorts of pregnant women. METHODS: A comparative study with two cohorts comprising totally 2132 pregnant women were followed in two health and demographic surveillance sites, one rural and one urban in Hanoi province, Vietnam. The women were quarterly interviewed using a structured questionnaire until delivery. The primary information obtained was the number and the content of ANC visits. RESULTS: Almost all women reported some use of ANC. The average number of visits was much lower in the rural setting (4.4) than in the urban (7.7). In the rural area, 77.2% of women had at least three visits and 69.1% attended ANC during the first trimester. The corresponding percentages for the urban women were 97.2% and 97.2%. Only 20.3% of the rural women compared to 81.1% of the urban women received all core ANC services. As a result, the adequate use of ANC was 5.2 times in the urban than in the rural setting (78.3% compared to 15.2%). Nearly all women received ultrasound examination during pregnancy with a mean value of 6.0 scans per woman in the urban area and 3.5 in the rural. Most rural women used ANC at commune health centres and private clinics while urban women mainly visited public hospitals. Expenditure related to ANC utilization for the urban women was 7.1 times that for the urban women. CONCLUSION: The women in the rural area attended ANC later, had fewer visits and received much fewer services than urban women. The large disparity in ANC adequacy between the two settings suggests special attention for the ANC programme in rural areas focusing on its content. Revision and enforcement of the national guidelines to improve the behaviour and practice of both users and providers are necessary. Key words: Antenatal care, adequacy, disparities, urban - rural comparison, Vietnam.
