OBJECTIVE: The prevalence of childhood sexual abuse among Latino adult men who have sex with men who live in the US was estimated because a history of childhood sexual abuse increases HIV sexual risk behaviors and other negative health outcomes in adulthood. METHOD: The Urban Men's Health Study is a random-digit telephone probability survey of 2881 adult men who have sex with men (MSM) aged 18 years or older residing in San Francisco, New York, Los Angeles, and Chicago. Self-reported history of childhood sexual abuse was the main outcome measure gathered from 2692 MSM. RESULTS: A significantly higher proportion of Latino MSM reported sexual abuse before age 13 (22%) than did non-Latino MSM (11%). CONCLUSIONS: Latino MSM are twice as likely to report a history of childhood sexual abuse than are non-Latino MSM. Given the association between childhood sexual abuse and increased risk for HIV and other negative health outcomes, health providers must remain vigilant to the possibility of childhood sexual abuse histories among their Latino patients.  相似文献

This article examines the relationship between public opinionand the transformation of the Soviet Union. Results of an August1990 survey showed that the majority of adults supported democraticreform, but lacked confidence in the Soviet regime. Young andmiddle-aged people, urban residents, and those with higher educationtended to be more supportive of democratic reform and more alienatedfrom the regime. The nationalities differed widely in supportfor democratic reform and confidence in the regime. In the partlydemocratized political system, Boris Yeltsin acquired a broadfollowing by appealing to the electorate and advocating radicalchange. A February 1991 poll showed that his support was greatestamong Russians who backed the Russian parliament and stronglyendorsed democratic reform and private enterprise. With suchbacking, Yeltsin won the June 1991 Russian presidential electionand then mobilized popular opposition to the August coup attempt.The coup's failure dealt a fatal blow to Communist rule, Gorbachev'sleadership, and the Soviet Union itself.  相似文献

This Monte Carlo study examines the performance of fit indices commonly used by applied researchers interested in finite mixture modeling for the purposes of classification. Conditions for the simulation study were selected to reflect conditions found in applied educational and psychological research. The factors included in the investigation were metric level of indicators, sample size, and class prevalence. All models contained a combination of categorical and continuous indicators. All categorical indicators were dichotomous, and continuous indicators were normally distributed. The fit indices examined were Akaike’s information criterion, Bayesian information criterion (BIC), sample size-adjusted Bayesian information criterion (SSBIC), integrated classification likelihood criterion with Bayesian-type approximation, and Lo–Mendell–Rubin likelihood ratio test. Overall, SSBIC tended to identify the correct solution with higher frequency than other indices. BIC tended to identify the correct solution with higher frequency than the other indices in models with more continuous than categorical indicators, or when rare classes were absent.  相似文献

European leaders and the popular media have shown a new-found interest in happiness as a socio-political value and goal. A growing body of research attempts to identify the conditions under which humans experience the highest levels of happiness, life-satisfaction or subjective well-being. This essay examines what makes a contemporary science and politics of happiness possible by taking a critical look at such efforts to define, measure and promote happiness, while seeking out a range of diverging, often paradoxical, cultural discourses of happiness. The essay covers the following themes: happiness is attainable; happiness is lost; happiness is obligatory; happiness is impossible; and, happiness is inauthentic. The essay critically examines political uses of the word happiness, disrupting received opinions about this contested term.  相似文献
