ABSTRACT

BACKGROUND: Online sexual experiences (OSEs) are becoming increasingly common in young adults, but existing papers have reported only on specific types of OSEs and have not shown the heterogeneous nature of the repertoire of OSEs. The use patterns of OSEs remain unclear, and the relationships of OSEs with sexual risk behaviors and behavioral health outcomes have not been evaluated. OBJECTIVE: This study aimed to examine the latent heterogeneity of OSEs in young adults and the associations with sexual risk behaviors and behavioral health outcomes. METHODS: The 2021 Youth Sexuality Study of the Hong Kong Family Planning Association phone interviewed a random sample of 1205 young adults in Hong Kong in 2022 (male sex: 613/1205, 50.9%; mean age 23.0 years, SD 2.86 years) on lifetime OSEs, demographic and family characteristics, Patient Health Questionnaire-4 (PHQ-4) scores, sex-related factors (sexual orientation, sex knowledge, and sexual risk behaviors), and behavioral health outcomes (sexually transmitted infections [STIs], drug use, and suicidal ideation) in the past year. Sample heterogeneity of OSEs was analyzed via latent class analysis with substantive checking of the class profiles. Structural equation modeling was used to examine the direct and indirect associations between the OSE class and behavioral health outcomes via sexual risk behaviors and PHQ-4 scores. RESULTS: The data supported 3 latent classes of OSEs with measurement invariance by sex. In this study, 33.1% (398/1205), 56.0% (675/1205), and 10.9% (132/1205) of the sample were in the abstinent class (minimal OSEs), normative class (occasional OSEs), and active class (substantive OSEs), respectively. Male participants showed a lower prevalence of the abstinent class (131/613, 21.4% versus 263/592, 44.4%) and a higher prevalence of the active class (104/613, 17.0% versus 28/592, 4.7%) than female participants. The normative class showed significantly higher sex knowledge than the other 2 classes. The active class was associated with male sex, nonheterosexual status, higher sex desire and PHQ-4 scores, and more sexual risk behaviors than the other 2 classes. Compared with the nonactive (abstinent and normative) classes, the active class was indirectly associated with higher rates of STIs (absolute difference in percentage points [Δ]=4.8%; P=.03) and drug use (Δ=7.6%; P=.001) via sexual risk behaviors, and with higher rates of suicidal ideation (Δ=2.5%; P=.007) via PHQ-4 scores. CONCLUSIONS: This study provided the first results on the 3 (abstinent, normative, and active) latent classes of OSEs with distinct profiles in OSEs, demographic and family characteristics, PHQ-4 scores, sex-related factors, and behavioral health outcomes. The active class showed indirect associations with higher rates of STIs and drug use via sexual risk behaviors and higher rates of suicidal ideation via PHQ-4 scores than the other 2 classes. These results have implications for the formulation and evaluation of targeted interventions to help young adults.

ABSTRACT

OBJECTIVES: This is a qualitative study which aims to understand the lived experience of dietary changes among Chinese survivors of colorectal cancer who participated in a dietary intervention. SETTING: The surgical and oncological departments of four public hospitals in Hong Kong. PARTICIPANTS: Fifty-five Chinese colorectal cancer survivors who were aged 18 years or above and had received potentially curative treatment in the surgical and oncological departments in Hong Kong were examined. Participants' mean age was 64 years, with 29 (53%) males. INTERVENTION: A 12-month dietary intervention delivered via face-to-face motivational interviews, fortnightly motivational phone calls, monthly electronic pamphlets, quarterly newsletters and quarterly group meeting. OUTCOME MEASURE: We adopted the qualitative approach to capture participants' perspectives and to apply the understanding pragmatically in everyday life. Content analysis was conducted. RESULTS: We identified themes of motives to changes of dietary practices including (1) individual commitment to dietary change; (2) adaptive strategies in interpersonal contexts and (3) working with healthcare professionals during the journey. CONCLUSIONS: The findings demonstrated how Chinese custom and culture posing unique challenges to colorectal cancer survivors and the need of having dietary advice from healthcare professionals. Participants were motivated to change their eating habits by support from family, friends and healthcare professionals. Our findings could help healthcare professionals provide specific dietary advice and guidance to Chinese colorectal cancer survivors. TRIAL REGISTRATION NUMBER: NCT01708824.

ABSTRACT

Given that the perinatal period is a time of increased risk for pregnant women to manifest mental health problems, the identification of antenatal hypomanic symptoms is particularly important. However, data on antenatal hypomanic symptoms is lacking. The present study was aimed at filling this research gap by investigating the prevalence of hypomanic symptoms, including the "active-elated" and "irritable/risk-taking" sides of hypomanic symptoms at the first trimester, and examining their associations with anxiety and depressive symptoms at the following time points: the first trimester, the second trimester, and up to 6-week postpartum. A prospective longitudinal design with a quantitative approach was adopted. A consecutive sample of 229 pregnant Chinese women in Hong Kong was assessed. Hypomanic symptoms were assessed with the Hypomania Checklist-32 (HCL-32). Of the sample, 43.6% had elevated levels of hypomanic symptoms in the first trimester. Multiple regression analysis showed that after adjusting for potential confounding factors, irritable/risk-taking symptoms were independently associated with higher anxiety symptoms in the first and second trimesters and in the 6-week postpartum period. Primary healthcare practitioners should be made aware of antenatal hypomanic symptoms in pregnant women to facilitate early identification and intervention for anxiety and depression to improve the well-being of both mothers and infants.

ABSTRACT

Objective: This study aims to evaluate the reliability and validity of the translated Chinese-Cantonese version of the Pregnancy-Related Anxiety Questionnaire-Revised (PRAQ-R) in a sample of pregnant women in Hong Kong, China. It also aims to determine whether pregnancy-related anxiety changes significantly across trimesters and if it is differentiated from general anxiety and depression.Method: This study adopts a prospective longitudinal design with a quantitative approach. A consecutive sample of 186 Chinese pregnant women from hospitals in Hong Kong are assessed using the translated Chinese-Cantonese version of the PRAQ-R and other standardized instruments at three time points during the first to third trimester.Results: A confirmatory factor analysis revealed a three-factor structure of the Chinese-Cantonese version of the PRAQ-R, including fear of giving birth, fear of bearing a physically or mentally handicapped child, and concern about one's appearance. The internal consistency was excellent (α = 0.88 to 0.91) for all of the items in the PRAQ-R across the three trimesters. The average variance extract (AVE) and composite reliability (CR) for each factor were greater than the recommended level of CR > 0.70 and AVE > 0.50. Multiple regression analyses showed that a combination of general anxiety and depression explained a small proportion of the variance (10-29%) in the PRAQ-R subscales during the three trimesters.Conclusions: The Chinese-Cantonese version of the PRAQ-R has good validity and reliability, and the results provide evidence of its relevance for Chinese pregnant women with pregnancy-related anxiety in Hong Kong. The finding also shows that pregnancy-related anxiety is a relatively distinctive form of anxiety that is different from general anxiety and depression.

ABSTRACT

BACKGROUND: Pregnancy is a time of increasing vulnerability to the development of body dissatisfaction, anxiety, and depression. The present study aims to examine associations of body dissatisfaction with anxiety and depression at the following points: 6 months before pregnancy (retrospective report); in the first, second, and third trimesters of pregnancy; and up to 6 weeks postpartum. METHODS: A prospective longitudinal design with a quantitative approach was adopted. A consecutive sample of 1,371 Chinese pregnant women in Hong Kong was assessed using standardized instruments at four time points. RESULTS: A mixed-effects model with repeated measures revealed that body dissatisfaction and depression symptoms changed across different stages of pregnancy. Hierarchical multiple regressions showed that, after adjusting for the identified risk factors, body dissatisfaction before and during pregnancy were positively associated with antenatal anxiety and depression symptoms. Concurrent body dissatisfaction was positively associated with postpartum depression symptoms. LIMITATIONS: There was a high attrition rate in the follow-up assessments. Antenatal anxiety symptoms were assessed using the scale for general anxiety, which may not adequately capture the experience of anxiety among pregnant women. CONCLUSIONS: Primary healthcare practitioners should be made aware of body dissatisfaction among pregnant women in order to facilitate early intervention for anxiety and depression, because untreated psychological disturbance during pregnancy may persist into the postpartum period.

ABSTRACT

BACKGROUND: Little is known about sex knowledge, attitudes, and high-risk sexual behaviors among unmarried youth in Hong Kong. It is of public health importance to investigate this topic to inform sex education, policymaking, and prevention and intervention programs. METHODS: Based on the Youth Sexuality Survey conducted by Hong Kong Family Planning Association (FPAHK) in 2011, this study explored the characteristics of sexual knowledge, attitudes, and high-risk sexual behaviors among 1,126 unmarried youth aged 18 to 27 years. Multiple logistic regressions were performed to examine factors associated with unmarried youth's premarital sex, casual relationships, multiple sex partners, and premarital pregnancy. RESULTS: Unmarried youth in Hong Kong had adequate sex knowledge, but contraceptive knowledge was deficient. The majority of unmarried youth (63.8%) held liberal attitudes toward premarital sex and about half held liberal attitudes toward any form of sexual activity and premarital pregnancy. Around 60% held conservative attitudes toward causal sex relationships and multiple sex partners. Males tended to hold more liberal attitudes toward high-risk sex behaviors than female youth. Approximately 41.5% of unmarried youth reported having engaged in premarital sex, whereas less than 10% engaged in high-risk sexual behaviors. Males also reported higher amounts of premarital sex, casual sex relationships, and multiple sex partners. Females reported higher levels of sexual coercion. Logistic regressions indicated that being older, coming from a divorced family, out of school status and liberal attitudes toward risky sex behavior were more likely to engage in premarital sex or high-risk sex behaviors, and being female, being better educated and being immigrants were less likely to engage in premarital sex. However, being immigrants was more likely to engage in casual relationship and to have multiple partners. CONCLUSIONS: Premarital sex is becoming more prevalent among unmarried youth in Hong Kong, and a small proportion of young adults are engaging in high-risk sexual behaviors. Sex education and HIV prevention programs should equip them with adequate knowledge on contraception and condom use. Intervention programs can start with their attitudes toward sex.

ABSTRACT

BACKGROUND: Despite increasing concern over the prevalence of non-suicidal self-injury (NSSI) among adolescents, there is debate about its classification as a stand-alone psychiatric diagnosis. This study investigated the patterns, co-occurrence, and correlates of NSSI and other suicidal behaviors among a representative community sample of in-school adolescents. METHODS: A cross-sectional survey of 2,317 adolescents was conducted. Participants were asked to self-report NSSI, suicidal ideation, suicide attempt, and psychosocial conditions over the past 12 months. Logistic regression and cumulative logit modeling analyses were conducted to investigate the different and similar correlates among these self-harm behaviors. RESULTS: The age-standardized prevalence rates of NSSI among male and female adolescents were estimated to be 13.4 and 19.7 %, respectively, compared with 11.1 and 10.1 % for male and female suicide attempt. Only a small proportion engaged in NSSI exclusively in the past year. NSSI by burning or reckless and risky behaviors, frequent drinking, and sexual experience were associated with increasing severity level of suicidal behaviors among individuals with NSSI. CONCLUSIONS: NSSI is prevalent among in-school adolescents in Hong Kong. However, it co-occurs with suicidal ideation and suicide attempt. High lethality of NSSI, frequent drinking habit, and lifetime sexual experience are suggested to be indicators for screening potential suicide attempters among those having NSSI.

ABSTRACT

BACKGROUND: Body shape dissatisfaction has been thought to have an indispensable impact on weight control behaviors. We investigated the prevalence of body shape dissatisfaction (BSD) and explored its association with weight status, education level and other determinants among young adults in Hong Kong. METHODS: Information on anthropometry, BSD, and socio-demographics was collected from a random sample of 1205 young adults (611 men and 594 women) aged 18-27 in a community-based household survey. BSD was defined as a discrepancy between current and ideal body shape based on a figure rating scale. Cross-tabulations, homogeneity tests and logistic regression models were applied. RESULTS: The percentages of underweight men and women were 16.5% and 34.9% respectively, and the corresponding percentages of being overweight or obese were 26.7% and 13.2% for men and women respectively. Three-quarters of young adults had BSD. Among women, 30.9% of those underweight and 75.5% of those with normal weight desired a slimmer body shape. Overweight men and underweight women with lower education level were more likely to have a mismatch between weight status and BSD than those with higher education level. After controlling for other determinants, underweight women were found to have a higher likelihood to maintain their current body shapes than other women. Men were found to be less likely to have a mismatch between weight status and BSD than women. CONCLUSIONS: Overweight and obesity in men and underweight in women were prevalent among Hong Kong young adults. Inappropriate body shape desire might predispose individuals to unhealthy weight loss or gain behaviors. Careful consideration of actual weight status in body shape desire is needed in health promotion and education, especially for underweight and normal weight women and those with a low education level.
