The influence of childhood abuse and prenatal intimate partner violence on childbirth experiences and breastfeeding outcomes.

BACKGROUND: Despite the detrimental effects and life-course health consequences of violence exposure, relatively few studies have adequate capacity to investigate the evolution of violence from childhood to motherhood. OBJECTIVE: This study aims to examine the cyclical nature of childhood abuse and prenatal inter-partner violent victimization (p-IPV) and its adverse impact on childbirth trauma and exclusive breastfeeding (EBF) practice in Vietnam. METHOD: Using a prospective birth cohort, 150 pregnant women were recruited in the third trimester of pregnancy in Hue city in central Vietnam (Wave 1-Baseline) and re-interviewed approximately three months after delivery (Wave 2-Follow-up). The direct and indirect effects of violent victimization on subsequent childbirth experience (measured by Birth Memories and Recall Questionnaire) and EBF practice were estimated by using augmented-inverse-probability-weighted models, sensitivity analysis, and structural equation model. RESULTS: Detrimental and prolonged effects of the inter-generational cycle of violence transverse childhood to motherhood. Women who experienced either childhood abuse or p-IPV violence were more likely to experience negative emotional childbirth memories [ARR 1.21, 95 % CI (1.04, 1.39)]. Evidence also suggested that not continuing to exclusively breastfeed at 3 months post-partum was strongly associated with prenatal depression, young age, and perceived low social status during pregnancy. Perceived strong connectedness among extended family members and social networks (i.e. nexus among family, friends, and neighborhood) provided a buffering effect by preventing EBF termination. CONCLUSION: This research provides insights into the protective role of social connectedness in improving breastfeeding practice. It is vital to establish wholistic antenatal care and social service system to offer specialized support and response for victims of violence and mitigate the long-term sequelae of traumatic events.

Acceptance and Willingness to Pay for Vaccine Against Human Papilloma Virus (HPV) Among Parents of Boys in Central Vietnam.

Human papilloma virus (HPV) vaccine for adolescents was recommended as an effective prevention strategy of HPV-related cancers. In Vietnam, HPV vaccination has not been introduced to male adolescent. This study was conducted to examine the acceptance of having boys vaccinated against HPV and its underlying reasoning, and to identify their parent's willingness to pay (WTP) for HPV vaccination in central Vietnam. 785 parents of boys were directly interviewed based on a structured questionnaire. Parent's acceptability of HPV vaccine for their sons was identified by one question with response on 3-point scale (agree, don't know, and disagree). Multivariate logistic regression model was used to determine contributing factors to participant's acceptance. Bidding game method was applied to elicit WTP values for HPV vaccination with initial bid of 161.2 USD. The results showed that 49.2% of parents agreed to have their sons vaccinated against HPV. Factors that influenced parent's acceptance including son's age older than 12 years (OR = 1.5; 95% CI: 1.08-1.98); being eldest son (OR = 1.6; 95% CI: 1.13-2.19), being mother (OR = 1.4; 95% CI: 1.01-1.91), parents with high educational level (OR = 1.7; 95% CI: 1.11-2.47) and their knowledge of HPV and HPV vaccine (OR = 1.8; 95% CI: 1.23-2.65). Average WTP value for full doses of HPV vaccine was 137.5 USD, ranging between 9 USD and 188.3 USD. Parents' knowledge of HPV and HPV vaccine was the only factor affecting WTP value (Rho: 0.11; p-value: 0.030). The findings suggest a strategy be introduced for HPV vaccination to male adolescents in Vietnam.

Effect of intimate partner violence during pregnancy on maternal mental health: a cohort study in central Vietnam.

This study aims to explore the effects of intimate partner violence during pregnancy (p-IPV) on postpartum depression among women in central Vietnam. p-IPV was defined among 150 women aged 18 years and older in the third trimester of their pregnancy. Baseline data was collected between February and May 2019, and then those women were followed up to 3-5 months after childbirth to assess depression using the Patient Health Questionnaire-9 (PHQ-9). Data collection was completed in September 2019. Relative risk was estimated to identify the effect of p-IPV on maternal postpartum depression. Twenty-one women reported IPV during pregnancy. In the follow-up assessment, 8 of 21 mothers exposed to p-IPV and 23 of 127 mothers not exposed to p-IPV developed postpartum depression. p-IPV including emotional and physical violence were increased the risk of postpartum depression. The findings support evidence that p-IPV increases the risk of postpartum depression among women in central Vietnam.

Depression and its associated factors among pregnant women in central Vietnam.

To date, little attention has been given to prenatal depression, especially in low and middle-income countries. The aim of this research was to assess the prevalence of depression and its associated factors amongst pregnant women in a central Vietnamese city. This cross-sectional study included 150 pregnant women from 29 to 40 weeks of gestation, from eight wards of Hue city, via quota sampling from February to May 2019. We employed the Patient Health Questionnaire (PHQ-9) to assess depression. Findings suggest the need to provide routine screening of pregnant women in primary care for depressive symptoms and other mental health problems.

Willingness to Pay for Social Health Insurance in Central Vietnam.

BACKGROUND: A social health insurance (SHI) program was implemented in Vietnam in 1992. Participation is compulsory for some groups, such as formal-sector workers and voluntary for other groups. In 2013, 68% of the total population was covered by SHI, with most enrollees from compulsory groups. Enrollment has remained low among persons whose enrollment is voluntary. As a result, households face financial risk due to high out-of-pocket payments for health care. The goal of this study is to identify willingness to pay (WTP) for the SHI scheme among persons whose enrollment is voluntary and to examine factors that influence their choice. METHOD: Three hundred thirty-one uninsured persons from three districts and one city of Thua Thien Hue province were interviewed face to face using a structured questionnaire. Contingent valuation technique was used to assess the WTP among the study participants. Each individual was asked to choose the maximum premium they were willing to pay for a health insurance card per year with three copayment levels of 0, 10, and 20%. Seven premium levels were offered ranging from 0 to 900,000 Vietnamese Dong (VND) (42.12 USD). The mean WTP of respondents for each scenario was estimated. Multiple linear regression analysis was used to identify factors influencing WTP for SHI. RESULTS: The survey found that 73.1, 72.2, and 71.6%, respectively, for each copayment level, of the respondents would agree to participate in the SHI scheme and are willing to pay an annual premium of 578,926 VND (27.1 USD); 473,222 VND (22.1 USD); and 401,266 VND (18.8 USD) at the copayment levels of 0, 10, and 20%, respectively. The WTP for SHI is influenced by knowledge of SHI at all copayment levels (p value < 0.05). The more knowledge about SHI individuals have, the higher the WTP amount. Chronic disease was related to WTP only at a copayment level of 20% (p = 0.049). CONCLUSION: Enhanced awareness of the benefits of SHI among the population should contribute to expanding SHI coverage in Vietnam.

Cost-Effectiveness Analysis of a Screening Program for Breast Cancer in Vietnam.

OBJECTIVE: This study aimed to evaluate the cost-effectiveness of a screening program for breast cancer from the health care payers' perspective. METHODS: A Markov model was used to compare costs and effects of an annual screening program using clinical breast examination (CBE) with the absence of screening on a cohort of 4,103,285 asymptomatic women aged 40 years. The model was analyzed over the cohort's lifetime under the assumption that women participated in the screening program annually for 15 years. The model integrated both epidemiological and cost data for breast cancer from prior Vietnamese studies. Costs were measured in 2008 US dollars. Costs and effects were discounted annually at 3%. The incremental cost-effectiveness ratio (ICER) was defined as the difference in cost per life-years saved (LYS). One-way and probabilistic sensitivity analyses were implemented to assess the uncertainty of inputs. RESULTS: The ICER for the breast cancer screening program with CBE was US $994.96 per LYS compared with the absence of screening. Earlier initiation of the program at age 35 years increased the ICER to US $1196.68 per LYS, while extending the duration of time screened to age 60 years decreased the ICER. Changing the participation rate to 70%, reducing the specificity of CBE testing, and increasing the cost of the screening program by 30% raised ICER estimates to US $1419.32, US $1124.15, and US $1292.03 per LYS, respectively. CONCLUSION: Breast cancer screening with CBE for women aged 40 to 55 years is considered very cost-effective in Vietnam according to the World Health Organization criteria.
