ObjectiveThe study was conducted to estimate the prevalence of depressive symptoms and its related factors among students at Tra Vinh University, Vietnam.MethodsThe instrument used was a questionnaire of socioeconomic-demographic characteristics, educational characteristics, and the self-reported depression scale collected from the Center for Epidemiological Studies-Depression (CES-D) originally published by Radloff in 1977. Scores of 16–21 were considered as mild to moderate symptoms of depression, and scores above 21 were considered as symptoms of major depression. The Chi-square test was performed to compare prevalences.Results405 students (with 136 males and 269 females) aged 19 to 27 (the average age was 20.2) were interviewed. The mean score for the CES-D was 15.98, and the overall prevalence of depressive symptoms was 52.3%, including the mild to moderate symptoms of depression (24.2%) and the major depression (20.7%). The prevalence occupied 72.2% among students in poor and near-poor households (aOR = 3.06, 95% CI = 1.38–6.76, p = 0.006). The prevalence also was higher among those who had been drinking alcohol (59.7% with aOR = 2.02, 95% CI = 1.15–3.53, p = 0.014).). Depressive symptoms among first-year students were 39.9%, and 2nd-year students were 42.5% and tended to increase to 4th-year students (47.1%) with the p-value of 0.019.ConclusionThe overall prevalence of depression is relatively high among university students at Tra Vinh University, Vietnam. The prevalencesignificantly associates with characteristics such as household economics, behaviours and number of years studying at university. These results suggest that more attention should be directed to activities to reduce the prevalence of depressive symptoms, especially among students in the final years.

Objective: To determine the rate of urinary retention after vaginal delivery and evaluation some factorsrelated to urinary retention after vaginal delivery at Da Nang Hospital For Women And Chidren.Methods: Cross-sectional study describing 673 women giving birth vaginally, at Da Nang HospitalFor Women And Chidren from March 2018 to the end of September 2018. The pregnant womenin the research group will be examined, interviewed, and refer to the medical records to record thevariables according to the research questionnaire.Results: Women who are primigravida with postpartum urinary retention rate 6.6%, higher than2.4% for multigravida who have postpartum urinary retention. In infants with a weight of ≥ 3500grams, the prevalence of birth urinary retention was 16.7%, higher than that of women with babies<3500 grams with neonatal urinary retention (1.7%). The rate of postpartum urinary retention amongwomen who had a baby with a head circumference ≥ 36 cm was 24.3% higher than for women with ahead circumference <36 cm (3.6%). The rate of urinary retention in pregnant women: asisted vaginaldelivery was 50.0%; time of labor in stage 1 lasted ≥ 12 hours was 13.0%; the duration of second stagelabor was 16.4% prolonged, higher than the rate of urinary retention in the group of pregnant women:vaginal delivery (4.6%); period of labor for stage 1 <12 hours (2.1%); period of labor for stage 2 didnot last long (3.3%). In the group of women who did not exercise early after giving birth, the rate ofurinary retention was 37.5%, higher than this group of women with early movement after birth, 1.3%.Conclusion: The rate of urinary retention after vaginal delivery is 4.8%. Factors: giving birth incomparison, giving birth to a large baby with a gestational weight: ≥ 3500 grams, head circumference≥36 cm, asisted vaginal delivery, long stage 1 labor, long stage 2 labor, early postpartum inactivityincreases the risk of postpartum urinary retention

Objective The study was conducted to estimate the goiter prevalence, and the median urine iodine concentrations among schoolchildren aged 8–10 in Binh Dinh province, Vietnam. Methods A school-based cross-sectional survey was carried out from May 2016 to May 2017. A multistage, proportional-to-population-size sampling method with 30 clusters was used. The children were examined by palpation for the presence or absence of goiter based on the criteria of the World Health Organization (WHO), the United Nations Children's Fund (UNICEF), International Council for the Control of Iodine Deficiency (ICCIDD); urinary iodine was determined in microplates by a modification of the Sandell-Kolthoff reaction. The Chi-square test was used to compare prevalences, and the Chi-square test for trend was employed to assess the trend of goiter prevalence and urine iodine levels by age and economic-social areas. Results 1800 pupils from 8 to 10 years old including 900 males and 900 females were examined and 300 among them were tested for the urinary iodine concentration (UIC). The prevalence of goiter among schoolchildren was 6.6%. The prevalence of goiter tended to increase in areas with disadvantaged conditions, among which the urban areas occupied the lowest prevalence (5%) while the mountainous areas and Midland took the highest (8.8%) (the p -value of 0.0193). The median UIC of the study group was 159.9 µg/L; the 25 th and 75 th percentile value was 103 µg/L and 230.2 µg/L, respectively. Conclusion According to the WHO/UNICEF/ICCIDD classification, the goiter prevalence indicated that some regions of Binh Dinh province appeared to be slightly affected by iodine deficiency. These have characterized an important public health challenge, highlighting the need to eliminate iodine deficiency disorders in these areas.
