Perceptions of Dentists and Non-Professionals on Some Dental Factors Affecting Smile Aesthetics: A Study from Vietnam.

Aim: It is important to meet the aesthetic expectation regarding the smile concept of both dentists and non-professionals after treatment is complete. Therefore, the study aims to evaluate the effects of altered displays in incisors, gingival margin, and other smile-related-factors on dentists' vs. non-professionals' aesthetics perceptions. Materials and method: We altered the features of 42 digital smile photographs to generate the changed displays in incisors, gingival margin, and other smile-related-factors. Then, these altered photographs were presented to 51 dentists and 51 non-professionals, and each picture was rated by each participant with a visual analog scale ranging from 0 (very ugly) to 100 (very beautiful). Results: We found that the alterations in incisors, gingival margin, and other factors affected studied groups' aesthetic perception of smile. The ugly smile threshold rated by both groups for crown length of maxillary central incisors was 2.0 mm. This threshold was 2.5mm for dentists, with moving the gingival margin of maxillary lateral incisors to the incisal ridge. The ugly thresholds for other smile-related-factors were different between studied groups; for example, the ugly thresholds for gingival exposure levels were 3 and 4mm for dentists and non-professionals, respectively. Thus, our data indicate that altered displays in incisors, gingival margin, and other smile-related-factors affected perceptions of both studied groups on smile aesthetics, but dentists tended to feel more refined than non-professionals. Dentists and non-professionals had significantly different aesthetic perceptions of the alteration of the gingival exposure level. Conclusion: Both dentists and non-professionals' perceptions should be fully considered during orthodontic and prosthodontic treatment to achieve optimum aesthetic results.

Intimate Partner Violence among Pregnant Women and Postpartum Depression in Vietnam: A Longitudinal Study.

BACKGROUND: Exposure to intimate partner violence during pregnancy is associated with a wide range of adverse reproductive health outcomes. However, detailed knowledge on the association between specific types of exposure to partner violence and postpartum depression is limited. PURPOSE: The aim of the present study was to investigate the association between exposure to emotional violence, physical violence, and sexual violence during pregnancy and postpartum depression among women in northern Vietnam. METHODS: The study was designed as a longitudinal study, which included a total of 1,337 women. The study participants were recruited from 24 communes in Dong Anh District, Hanoi, Vietnam, and interviewed four times: (a) at enrolment (which took place no later than week 24 of the pregnancy); (b) at a gestational age of 30-34 weeks; (c) at delivery; and d) 4-12 weeks after delivery. Emotional, physical, and sexual violence exerted by the intimate partner were measured using a modified version of the questionnaire initially developed by the World Health Organization, and signs of depression were measured by the Edinburgh Postpartum Depression Scale. RESULTS: More than one-third of the women (35.3%) experienced at least one type of violence during their pregnancy and 8.2% of the women reported postpartum depression. The results of multivariate analyses showed that both physical and sexual violence were statistically significantly associated with postpartum depression (AOR=2.75, 95%CI: 1.19-6.35 and AOR=1.93, 95%CI: 1.01-3.73, respectively). CONCLUSIONS: The results showed strong and statistically significant associations between partner violence and postpartum depression. These findings clearly demonstrate a crucial need for relevant health professionals to identify women who are exposed to partner violence and screen for postpartum depression in order to mitigate the negative mental health outcomes among Vietnamese women.

Emotional violence and maternal mental health: a qualitative study among women in northern Vietnam.

BACKGROUND: Worldwide, intimate partner violence (IPV) during pregnancy is a pressing and prevalent public health problem. Existing research has found close associations between IPV and perinatal mental health, yet little is known about women's own perceptions of these associations. This study aimed to explore Vietnamese women's experiences of emotional partner violence and their perceptions of the implications of such violence for their mental health. METHODS: The data were collected through in-depth interviews with 20 women living in Hanoi, Vietnam who had reported exposure to emotional partner violence and attained high depression scores in a prospective cohort study. Ten women were pregnant and ten had recently given birth. The data were analysed by qualitative content analysis. RESULTS: The women described emotional partner violence as a major life stressor. Their accounts pointed to three particularly significant dimensions of emotional violence: being ignored by the husband; being denied support; and being exposed to controlling behaviours. These experiences affected the women's sense of wellbeing profoundly, causing sadness and distress. The women's accounts indicated that experiences of emotional violence were significantly shaped by dominant kinship arrangements: practices of patrilocal residence and principles of patrilineal descent tended to aggravate women's vulnerabilities to partner violence. CONCLUSIONS: This qualitative study from Vietnam documents close associations between emotional partner violence and perinatal distress, while also pointing to kinship arrangements as particularly significant structural contexts shaping women's experiences of partner violence. The study findings suggest that effective policies and programs to decrease women's vulnerability to intimate partner violence must take into account the kinship arrangements that prevail in a given society.

Contraceptive use among HIV-positive women in Quang Ninh province, Vietnam.

OBJECTIVE: To investigate contraceptive use among HIV-positive women in Ha long city and Cam Pha town of Quang Ninh, a Northern province of Vietnam. METHODS: Cross-sectional questionnaire study among HIV-positive women identified through the district HIV/AIDS register. Information on socioeconomic characteristics and contraceptive use before and after HIV diagnosis was obtained through structured questionnaires. Chi-square testing was used to assess whether the included women differed from the target population in terms of age. Crude Odds ratios (ORs) were calculated to show the association between contraceptive use and the women's socioeconomic characteristics. Logistic regression analyses were applied to adjust for possible confounding. The women's contraceptive use before HIV testing and after HIV testing was described and compared by Chi-square testing, and the association between post-test counselling and the women's use of condom was assessed by ORs. RESULTS: Of the 351 participants, 63% stated they had used contraception before HIV diagnosis and 89% stated they had used contraception after HIV diagnosis. Forty six per cent of the women had been using either the pill or an intrauterine device (IUD) before the diagnosis whereas the same applied for only 8% of the women after diagnosis. Thirty-nine per cent stated they had been using condom before HIV diagnosis whereas 87% stated condom use after HIV diagnosis. Condom use was more common among women who had received post-test counselling (OR 3.03, 95% CI 1.03-8.90). CONCLUSIONS: A change of contraceptive methods from IUD and oral contraception before HIV diagnosis to condom use after HIV diagnosis was observed. The women's use of condoms after HIV diagnosis was associated with having received post-test counselling.

Prevention of mother-to-child transmission--precarious hopes and childbearing choices among HIV-infected women in a northern province of Vietnam.

The world over, increased access to treatment brings reproductive hope to women infected with HIV. Yet, despite the expanding availability of programs for prevention of mother-to-child transmission, HIV-positive women continue to face numerous problems and uncertainties in the realm of reproduction. The results reported here are derived from ethnographic research conducted in a northern province of Vietnam in 2007. The authors interviewed 32 HIV-positive women, exploring the hopes that they invested in prevention of mother-to-child transmission, and examining how this new technology enhanced the women's faith in their futures and childbearing capacities. Based on the findings, the authors discuss the new forms of gendered uncertainty that arise in the era of HIV/AIDS in Vietnam. They conclude that prevention of mother-to-child transmission, including the counseling offered by health providers, plays an important role in building and strengthening reproductive hopes for women living with HIV, while also generating new concerns.

Posttest counseling and social support from health staff caring for HIV-infected pregnant women in Vietnam.

Women with HIV who want to have children face a range of challenges, quandaries, and hard decisions. This article examines the role of health staff in supporting HIV-infected pregnant women who desire to maintain their pregnancies. The article is derived from anthropological research conducted in Vietnam's Quang Ninh Province, an area that has a high HIV prevalence rate and is covered under the government's prevention of mother-to-child transmission program. The study included in-depth interviews with 23 HIV-infected women who had either recently given birth or were pregnant at the time of the research. Results showed that women were satisfied with the services they received from the program. The women believed that health care staff offered them not only medical care but also social and emotional support. The article concludes that the health care system is a vital point of support for pregnant women with HIV.
