This study aimed to examine the association between sexual orientation and health disparities among a stratified random sample of 3776 secondary students in Hong Kong. The prevalence of homosexuality and bisexuality were 1.5% and 2.6% in boys and 1.8% and 3.7% in girls, respectively. A total of 10.7% of boys and 8.8% of girls were unsure of their sexual orientation. Homosexual and bisexual boys reported poorer physical and mental health than their heterosexual peers. Homosexual and bisexual boys were more likely to engage in smoking, frequent drinking, and vaginal sex and be subjected to sexually transmitted disease and sexual victimization. However, lesbian and bisexual girls were less likely to engage in risky health behaviors except for smoking and being subjected to sexual victimization. There is a gender-specific problem that may warrant prevention and intervention programs to address the unique health issues facing homosexual and bisexual adolescents in Hong Kong. 相似文献

AbstractObjective: Existing literature on young adults’ e-cigarette and polysubstance use focused on college students. This study examined the differences between college and noncollege groups on prevalence and patterns of e-cigarette and other substance use using data from a national survey. Participants: Adults aged 18–24 from the 2013–2014 Population Assessment of Tobacco and Health Study (n?=?6,608). Methods: Independent sample t-tests and Chi-square tests were conducted to examine group differences. Results: Noncollege young adults had higher prevalence of cigarette, e-cigarette, and marijuana use; college students had higher prevalence of alcohol use. Among current e-cigarette users, college students had higher prevalence of polysubstance use of alcohol and marijuana. College students used e-cigarettes for socializing purposes more. Conclusions: Differences in prevalence and patterns of e-cigarette and other substance use between college and noncollege groups exist. Future interventions should target the social context of college life and reach out to noncollege young adults in workplaces. 相似文献

Objective: To test the effectiveness of a text-message intervention to promote sleep hygiene to improve sleep in young adult college students. Participants: A convenience sample of undergraduate students from one Southwestern university (n = 96), 18–26 years old, recruited in August 2015. Methods: A 2-group pretest-posttest experimental design assigned participants to receive biweekly text messages about sleep hygiene or healthy behaviors for 6 weeks. Survey questions addressed sleep knowledge, sleep hygiene, self-efficacy for sleep hygiene, and sleep quality at baseline and posttest. Results: Though not significant, sleep quality, sleep hygiene, and sleep knowledge improved in both groups. Conclusions: Self-efficacy for sleep hygiene is a modifiable factor that may serve to improve sleep quality. Sleep quality improved in both groups. Text messaging is a feasible approach to delivering an intervention to promote healthy behaviors among young adults. 相似文献

A territory‐wide two‐stage stratified random sample of 2,282 community‐dwelling Hong Kong adults were surveyed between 2014 and 2015 to investigate the association between poverty and regular source of primary care utilization. Poverty was operationalized by income‐poverty and deprivation. About 94% of our sample reported having regular source of primary care (Western and/or Chinese medical practitioner) and about 69% among them were in private sector. Multivariable logistic regression showed that people who were income‐poor and deprived were less likely to have regular source of primary care (income‐poor: OR = 0.523, p = .027; deprived: OR = 0.488, p = .007) and visit private primary care doctors (income‐poor: OR = 0.445, deprived: OR = 0.222, both p < .0001). Those who had chronic diseases were more likely to have regular source of primary care (multimorbid: OR = 10.709, p < .0001), but less likely to access care in the private sector (one chronic disease: OR = 0.690, p = .019; multimorbid: OR = 0.374, p < .0001) than those without. Further, being older and less skilled were significantly associated with less likelihood of visiting a private doctor. Path analysis showed that the number of chronic diseases had significant indirect effect on having regular source of primary care with being income‐poor and deprived as the mediators (β = ?.0183, p = .0016). Therefore, despite a public health‐care system that aims to deny no one from adequate health care for lack of means, regular source of primary care in Hong Kong is found to be pro‐rich. Future policies should tackle the problem of health‐care inequalities to meet the needs of the underprivileged. 相似文献

This article makes use of survey data collected in 1992 and 2007 to examine the question of whether or not Postmaterialism
is gradually becoming manifest in Hong Kong and to explore the applicability of Postmaterialist theory to this affluent Chinese
society. Our findings basically support the hypotheses of the theory that the continued socioeconomic development of Hong
Kong is giving rise to a populace that is increasingly inclined towards Postmaterialism. Younger people are more Postmaterialist
than their seniors. In addition, Postmaterialists are more likely than Materialists to support the ‘new politics’ and democracy.
Nevertheless, Hong Kong is far from being a Postmaterialist society. Multivariate regression analysis also revealed that the
Materialist/Postmaterialist orientation is neither related to age nor to formative security.

Bayesian covariance matrix estimation using a mixture of decomposable graphical models 总被引:1,自引:0,他引:1

We present a Bayesian approach to estimating a covariance matrix by using a prior that is a mixture over all decomposable
graphs, with the probability of each graph size specified by the user and graphs of equal size assigned equal probability.
Most previous approaches assume that all graphs are equally probable. We show empirically that the prior that assigns equal
probability over graph sizes outperforms the prior that assigns equal probability over all graphs in more efficiently estimating
the covariance matrix. The prior requires knowing the number of decomposable graphs for each graph size and we give a simulation
method for estimating these counts. We also present a Markov chain Monte Carlo method for estimating the posterior distribution
of the covariance matrix that is much more efficient than current methods. Both the prior and the simulation method to evaluate
the prior apply generally to any decomposable graphical model. 相似文献

Positive assortative matching in terms of traits such as ethnicity and race has been prevalent in marital formation. One possible explanation for this is that spouses in endogamous marriages possess complementary skills and tastes that increase marital surplus. This paper aims to estimate the effects of ethnic assortative matching on a variety of household outcomes by using the exogenous variation in immigrant flows in the USA during the period 1900–1930 to disentangle the selection effect of partners. The major finding is that the complementarities in home production from same ethnic marriage enhances investment in household public goods such as childrearing and home ownership and reduces the market labor supply of wives. The OLS estimates of the sizes of these effects appear to be substantially biased downward, indicating positive selection into intermarriage in terms of unobservable traits that increase marital surplus. 相似文献
