'Hu Hong' (bad thing): parental perceptions of teenagers' sexuality in urban Vietnam.

BACKGROUND: Teenagers under 18 years old in Vietnam are considered as minors who usually lack the autonomy to make decisions. They are also sometimes viewed as contributors to social evils including crime, violence and substance use. Moreover, most Vietnamese teenagers have unsafe sex before marriage. The objective of this study is to explore the parental perceptions relating to their teenagers' sexuality, particularly the social and cultural forces, that may hinder access to sexuality information. METHODS: Guided by a Community Advisory Board (CAB), this qualitative study uses four focus group discussions (FGDs) consisting of 12 mothers and 12 fathers, as well as twelve individual in-depth interviews (IDIs) with a diverse sample of parents of teens in Ho Chi Minh City (HCMC), Vietnam. Content and discourse analysis were conducted, based on Foucauldian concepts. RESULTS: Four themes emerged: 1) Meanings of sexuality and sexuality education, 2) Early sexual intercourse destroys teenagers' future, 3) Teenagers are not hu hong (spoil/bad thing), are innocent and virgin, and 4) Policing and controlling of sexual intercourse among teens. Parents did not view their teenage children as sexual beings; those who are sexual are considered hu hong. Parents believed that teens need to be policed and controlled to prevent them from becoming hu hong, particularly girls. Controlling of sexuality information by parents was therefore common in HCMC, but differed by gender and educational levels of parents. For example, fathers more than mothers were not comfortable teaching their teenage children about sex and sexuality. Parents with higher education police their teenage children's usage of the Internet and social media, while parents with lower education control who can be friends with their teenage children. CONCLUSIONS: Vietnamese parents in general have negative views of sex and sexuality education for their teenage children. Recognizing that many Vietnamese teenagers have unsafe sex before marriage, parents need to change their perceptions and understand the importance of comprehensive sexuality education (CSE), which are included in UNESCO, UNFPA and UNICEF-developed CSE tools.

The seroprevalence of toxocariasis and related risk factors in children in Ho Chi Minh City, Vietnam: results from a school-based cross-sectional study.

BACKGROUND: Children are especially vulnerable to Toxocara infection and its severe complications; however, there have not been any published data on the disease prevalence and treatment effectiveness in the population of Vietnamese children. This study was conducted to determine the prevalence of toxocariasis and explore factors associated with Toxocara infection in children aged 3-15 y in Ho Chi Minh City, Vietnam. METHODS: We conducted a cross-sectional study using a multistage cluster sampling approach in public schools. Blood samples were collected, and toxocariasis cases were confirmed, based on a history of contact with dogs/cats and positive anti-Toxocara antibody detection via ELISA. We calculated the percentage of seropositive children across gender, grade levels, districts and caregiver education. Multiple regression models were employed to identify potential risk factors. RESULTS: Anti-Toxocara antibodies were found in 14.2% of the 986 children studied. Significant variations in seropositivity were observed across grade levels, districts and caregiver education levels. Multivariable analysis identified caregiver education, contact with dogs/cats and improper handling of pet feces as seropositivity risk factors. CONCLUSION: This was the first community-based prevalence study of toxocariasis in a pediatric population in Vietnam. Implementation of preventive measures such as public education, routine fecal examinations and chemotherapeutic treatment of animals is highly recommended.

The Underappreciated Benefits of Interleaving for Category Learning.

The present study examined the effects of study schedule (interleaving vs. blocking) and feature descriptions on category learning and metacognitive predictions of learning. Across three experiments, participants studied exemplars from different rock categories and later had to classify novel exemplars. Rule-based and information-based categorization was also manipulated by selecting rock sub-categories for which the optimal strategy was the one that aligned with the extraction of a simple rule, or the one that required integration of information that may be difficult to describe verbally. We observed consistent benefits of interleaving over blocking on rock classification, which generalized to both rule-based (Experiment 1) and information-integration learning (Experiments 1-3). However, providing feature descriptions enhanced classification accuracy only when the stated features were diagnostic of category membership, indicating that their benefits were limited to rule-based learning (Experiment 1) and did not generalize to information-integration learning (Experiments 1-3). Furthermore, our examination of participants' metacognitive predictions demonstrated that participants were not aware of the benefits of interleaving on category learning. Additionally, providing feature descriptions led to higher predictions of categorization even when no significant benefits on actual performance were exhibited.

Assessing Awareness of Colorectal Cancer Symptoms among Outpatients: A Cross-Sectional Study at a Hospital in Vietnam.

Colorectal cancer (CRC) is a prevalent cancer globally, including in Vietnam where its incidence is rapidly increasing. The aim of this study was to evaluate the awareness of signs, symptoms, and risk factors of colorectal cancer among outpatients at Hoa Hao Medic Company Limited, Ho Chi Minh City, Vietnam. A cross-sectional study was conducted, and a total of 441 people who visited Hoa Hao Medic Company Limited for a general health check-up and voluntarily agreed to participate in this study were recruited through the convenience sampling method. Data were collected through face-to-face structured interviews using the Bowel CAM questionnaire. According to the results, the highest percentage of well-recalled warning signs were "change in bowel habit" (36.7%) followed by abdominal pain (35.4%). Other warning signs such as weight loss and rectal bleeding were reported by 19.0% and 18.1% of participants, respectively. Over 42% of participants stated that they were unaware of any signs or symptoms. The most commonly identified risk factors for CRC were pollution (66.9%), genetics (50.6%), and an unhealthy/poor diet (53.7%) for unprompted questions. The overall awareness score of participants was 3.46/9 (SD ± 2.91) for signs and symptoms of CRC and 5.90/10 (SD ± 1.62) for risk factors. Univariate linear regression identified education level and occupation as predictors of higher CRC awareness. In conclusion, this study highlights that overall awareness of CRC is low among outpatients at Hoa Hao Medic Company Limited. Strategies to increase awareness, knowledge, and education programs are necessary to promote early detection of CRC and reduce its burden in Vietnam.

Social violence among Thai gender role conforming and non-conforming secondary school students: Types, prevalence and correlates.

BACKGROUND: Gender role non-conforming behaviors are a significant risk factor for school-related violence. The objective of this study is to describe the types, prevalence and correlates of social violence among Thai secondary school students, with a focus on gender role non-conformity. METHODS: This article uses secondary data from a national study of 2070 secondary school students aged 13-20 years representing Bangkok and all four regions of Thailand. Students were asked about their gender/sexual identity, self-perception of their masculinity or femininity, and experiences of social violence. Correlates of social violence were examined using multivariable logistic regression models. RESULTS: Prevalence of social violence victimization was high (57%). Most students considered themselves to be as masculine or as feminine as other members of their sex (82.6%), while 9.1% thought that they were less masculine/less feminine, and 8.3% thought they were more masculine/more feminine. Students who considered themselves less masculine or less feminine than others of their sex (AOR = 1.59, 95% CI: 1.13, 2.25) were more likely to experience social violence, compared to students who considered themselves equally masculine/feminine. Students who self-identified as lesbian, gay, bisexual or transgender (LGBT) (AOR = 1.37, 95% CI: 1.01, 1.86) were also more likely to experience social violence, compared to students who did not identify as LGBT. However, students who considered themselves more masculine or feminine than other students of their sex (AOR = 0.62, 95% CI: 0.44, 0.88) were less likely to experience social violence. DISCUSSION: Students who identified as LGBT, or considered themselves to be less masculine or less feminine than other students of their sex, had higher odds of social violence victimization. Anti-bullying campaigns need to emphasize that perpetrating social violence is not tolerated, and gender-based violence needs to be included in comprehensive sexuality education curricula.
