美国“安全约会”干预项目及其启示

亲密伴侣暴力(intimate partner violence)是全世界范围内的社会与公共卫生问题[1-2].恋爱暴力(dating violence)是亲密伴侣暴力的一种形式,是指在当前或曾经的恋爱关系中所实施的肢体、性或心理虐待,并通过威胁或强迫的手段来获取权力和对受暴者的控制[3-4].同亲密伴侣暴力一样,恋爱暴力主要分为4种形式:肢体暴力(physical violence)、心理暴力(psychological violence)、性暴力(sexual violence)与滋扰(stalking).肢体暴力包括拿会伤人的物件扔向对方、扭手臂、用刀或利器指向对方或用拳头重击等;心理暴力指的是威胁伴侣或伤害伴侣的自我价值感,如辱骂、故意刁难、威胁分手、羞辱伴侣等;性暴力指违背伴侣的意愿或没有得到伴侣的同意而发生的性行为,包括以武力逼迫伴侣发生性行为,以威胁逼迫伴侣发生性行为,逼迫伴侣与他人发生性行为,使用酒精或药物的影响与伴侣发生性行为,非自愿性的其他与性有关的行为;滋扰包括骚扰或烦扰伴侣,让对方感到恐惧与不安.构成骚扰或烦恼伴侣的行为包括诋毁、威胁或争辩、电话滋扰、跟踪或到对方的住所烦扰等[5].     

湖南省孕产妇亲密伴侣暴力发生及影响因素研究

目的 了解孕产妇在孕前和妊娠期亲密伴侣暴力(intimate partner violence,IPV)的发生情况,探索和识别影响亲密伴侣暴力发生的因素。 方法 通过湖南省某妇幼保健院产科门诊招募孕妇进行问卷调查,内容包括一般人口学特征,家庭条件,妊娠经历,社会支持和亲密伴侣暴力经历。 结果 本次回收有效问卷510份,共113例(22.2%)孕产妇有遭受亲密伴侣暴力的经历,其中68例(13.3%)是在孕前发生的亲密伴侣暴力,45例(8.8%)是在妊娠期发生亲密伴侣暴力;就暴力类型而言,精神暴力发生率最高,有97例(19.0%),其次为躯体暴力有21例(4.1%),性暴力最少,有6例(1.2%)。多因素logistic回归分析显示有不良妊娠史是孕前亲密伴侣暴力发生的危险因素(OR=2.941,95%CI:1.574~5.494),而社会支持中主观支持是妊娠期亲密伴侣暴力发生的保护因素(OR=0.803,95%CI:0.722~0.893)。 结论 孕产妇遭遇孕前和妊娠期亲密伴侣暴力将影响孕产妇及婴幼儿身心健康,在母婴保健工作中应增加对妇女精神暴力伤害及孕产妇亲密伴侣暴力发生的关注,并及早识别受害者的暴力经历,从而采取早期干预措施。

Abstract：

Objective To assess the prevalence of HIV and risky sexual behaviors among university students who have sex with men(MSM)in Beijing.Methods MSM students in the universities were mainly recruited via internet.Questionnaires were self-administered to collect social demographic information and AIDS-related risky sexual behaviors.After completing the questionnaire,blood sample was collected to determine HIV infection through serological testing.X2 test and logistic regression were employed for univariate and multivariate analysis,respectively.Results A total of 157 students were recruited with mean age of 22.7±2.8 years old,12.1%of them were minorities and 77.7% were self-identified as homosexual.98.1% had engaged in anal intercourse(AI)in their lifetime and 73.9%reported that AI was common sexual behavior they often practised.In the past 6 months,58.6% had ever had unprotected anal intercourse(UAI),58.0% never used condoms during oral intercourse,and 59.2% had multiple sex partners(≥2).Nearly half of them believed that they were at low or no risk of contracting HIV and the prevalence of HIV infection was 2.5%.Data from logistic regression analysis showed that ever having had sex with a casual partner in a lifetime (OR=13.10).understanding that serving an insertive role had less risk than being receptive during the AI (OR=3.37),and ever having been to a gay bar(OR=2.49)was independently related to having multiple sex partners in the past 6 months.Conclusion Despite the extensive programs on education,behaviors regarding UAI and ever having had multiple sex partners were silll commonly seen among university MSM students.Interventions were needed to prevent HIV transmission in this population.

Objective To understand the prevalence of and factors associated with unprotected anal intercourse(UAI)among men who have sex with men(MSM)in Beijing.Methods Five hundred MSM were recruited for a survey using Respondent Driven Sampling (RDS)method, from September to October in 2009. A computer-assisted, interviewer-administered questionnaire was used to gather information including demographics, sexual behaviors and condom use social norms(a scaled number). Variables were evaluated by using RDSAT and SAS software.Results Mean age of the participants was 30.6 years, with 96.0% of them as Han ethnicity and68.5% having had at least high school or higher education level. 72.8% of them were unmarried, with 61.7% of them identified themselves as homosexual, 61.2% had ＞ 1 male partners in the past six months, and the prevalence of UAI was 42.0%. Significant bivariate predictors of UAI would include condom use social norms score, role for anal sex with male sex partner, number of male sexual partners in the past 6 months and amount of alcohol consumed. In multivariable analysis, UAI was associated with a higher condom use social norms score(AOR= 1.2, 95%CI: 1.1-1.3), receptive anal intercourse(AOR=2.0, 95%CI: 1.3-3.2)and drinking alcohol more than 3 times per month in the past 12 months(AOR=1.6, 95%CI: 1.1-2.5). Conclusion The prevalence of UAI was high in the MSM community in Beijing, suggesting that efforts should be targeting on how to make the condom use a social norm and being promoted.

Objective This study was to identify the post-traumatic stress disorder(PTSD)changes and the relative risk factors within one year after Wenchuan earthquake among middle school students in the disaster area.Methods A total of 1966 students from 3 schools in Wenchuan earthquake region were selected as the target population.For each student,personal basic information and standard psychological scale(PCL-C,PSSS)were investigated by a self-administrated questionnaire in the 3rd,the 6th,the 9th and the 12th month after the earthquake,respectively.PTSD trends over the time and the associated risk factors were analyzed through the establishment of multi-level random coefficient model.Results There were 1677middle school students fully participated in the PTSD follow-up study by turning in the valid questionnaires.The averaged scores of PTSD at the time of the 3rd,the 6th,the 9th and the 12th month after the earthquake were 35.14 ± 11.08,32.90 ± 11.03,30.67 ± 11.28 and 29.75 ± 11.22,respectively.Meanwhile,the general incidences of PTSD were 36.6%(613/1677),30.7%(515/1677),24.8%(416/1677)and 22.2%(373/1677),respectively.The median score of perceived social support system was 60.00 and the general incidences of PSS was 17.20%(289/1677).The PTSD scores for the students had a decreasing trend during the period of our observation(βtime =-1.879,x2 = 47.03,P ＜0.05).The averaged scores for boys for the 4 follow-up studies were 33.71,31.61,29.66,28.83 ;for girls were 36.33,33.98,31.51,30.52; for junior school students were 35.46,33.28,30.18,29.22; for senior school students were 34.89,32.62,31.04,30.15.Moreover,two factors,gender and grade,were related with the decreasing trend(the trend for girls and senior school students was sharper than that for boys and junior school students)(βgender-time =-0.354,x2 = 4.83,P ＜0.05; βgrade-time = 0.622,x2 = 11.30,P ＜0.05).Conclusions The prevalence of PTSD was high.Meanwhile,there was a trend of self-recovery for adolescent's PTSD during the first year of post-earthquake,but boys and junior school students recovered more slowly.     

汶川地震灾区中学生地震创伤后应激障碍与领悟社会支持的关系

Objective To explore the relationship between post-traumatic stress disorder (PTSD) and perceived social support (PSS)ability among middle school students in earthquake-stricken areas after the Wenchuan earthquake accident. Methods A total of 1966 students from three secondary schools of Wenchuan earthquake-stricken areas were evaluated by PTSD Checklist-Civilian Version (PCL-C) and Perceived Social Support Scale (PSSS). Results The overall incidence rate of PTSD was 78.3%, with severe PTSD as 24.38%. Significant differences on the incidence rates of PTSD were found among the students who were in different PSS levels (P<0.05) and significant negative correlation existed between the levels of severity on PTSD and PSS (γ=-0.226, P<0.05). Significant differences on PTSD incidence rates were found among those students who were from different families or out-family PSS levels (P=0.009, P<0.05). Significant negative correlation existed between the severity of PTSD and family or out-family PSS level (γ=-0.176, P<0.05, γ=-0.214, P<0.05). Conclusion Relationships between the incidence rate, severity of PTSD and PSS levels existed among the middle school students in Wenchuan earthquake-stricken areas, with higher PSS, lower incidence rate and lighter severity of PTSD. Psychological intervention for earthquake-stricken students should be carried out.

Coercive forms of sexual risk and associated violence perpetrated by male partners of female adolescents

CONTEXT: Partner violence is associated with STDs among female adolescents, but the mechanisms underlying this association remain unclear. Sexually coercive and deceptive behaviors of male partners that increase female STD risk may be factors in this relationship. METHODS: A sample of 356 females aged 14–20 who attended adolescent health clinics in Greater Boston between April and December 2006 were assessed for physical and sexual violence perpetrated by male partners and for exposure to sexual risk factors. Adjusted logistic regression models were used to examine the associations between intimate partner violence and standard sexual risk behaviors (e.g., multiple partnerships) and coercive or deceptive sexual risk factors (e.g., coerced condom nonuse). RESULTS: More than two‐fifths of the sample had experienced intimate partner violence. In adjusted analyses, adolescents reporting intimate partner violence were more likely than others to report standard sexual risk behaviors—multiple partners, anal sex and unprotected anal sex (odds ratios, 1.7–2.2). They also were more likely to report coercive or deceptive sexual risk factors—partner sexual infidelity, fear of requesting condom use, negative consequences of condom request, and coerced condom nonuse (2.9–5.3). CONCLUSION: The high prevalence of intimate partner violence against young women attending adolescent clinics strongly indicates the need to target this population for abuse‐related interventions. This need is underlined by the observed association between partner violence and sexual risk involving coercion or deception by male partners. Clinic‐based STD and pregnancy prevention efforts should include assessment of sexual risk factors that are beyond the control of young women, particularly for those experiencing abuse.     

Intimate Partner Violence in Southwestern Nigeria: Are There Rural-Urban Differences?

The researchers in this study assessed the prevalence of different types and experience of intimate partner violence among 600 women aged 15 to 49 years in selected rural and urban communities in southwestern Nigeria between October and December, 2007. Lifetime prevalence of intimate partner violence was 64% in the rural and 70% in the urban areas. Controlling behavior was the most frequently reported type of intimate partner violence experienced by both groups of women, and sexual violence was reported least. More urban women reported sexual violence and controlling behaviors than rural women (16.4% versus 11.6% and 57.7% versus 42.0%, respectively). More rural women had experienced physical violence (28% versus 14%). More urban women experienced controlling behaviors, while more rural women experienced physical violence. In both locations, history of partners' involvement in physical fights was significantly associated with reporting sexual violence (rural: odds ratio [OR] = 3.9; 95% confidence interval [CI] 1.2–12.3; urban: OR = 8.4; 95% CI 1.4–51.8). History of alcohol consumption by partners was significantly associated with reporting physical violence (rural: OR = 2.3; 95% CI 1.2–4.4; urban: OR = 3.2; 95% CI 1.4–7.2). However, among rural respondents, younger partners were more likely to perpetuate controlling behavior (OR = 5.1; 95% CI 1.7–15.6) and being in a relationship for ≥10 years was related to psychological and physical violence. Among urban respondents, history of partners' involvement in physical fights was associated with controlling behavior (OR = 8.2; 95% CI 1.1–65.4) and physical violence (OR = 4.5; 95% CI 1.2–17.3). These results suggest that intimate partner violence is a frequent experience in women in both communities, although the types of intimate partner violence experienced differed, and multidisciplinary strategies are required to reduce intimate partner violence.     

Prevalence of partner violence in same-sex romantic and sexual relationships in a national sample of adolescents.

PURPOSE: To present the first national prevalence estimates of psychological and physical intimate partner violence between adolescents in same-sex relationships. METHODS: Analyses focus on 117 adolescents aged 12-21 years (50% female) from Wave II of the National Longitudinal Study of Adolescent Health who reported exclusively same-sex romantic or sexual relationships in the 18 months before interview. Items from the Conflict Tactics Scale were used to measure partner violence victimization. Data analysis included computation of prevalence estimates and a logistic regression analysis to assess associations between sociodemographic characteristics and violence victimization. RESULTS: Almost one-quarter of adolescents with same-sex romantic or sexual partners reported some type of partner violence victimization; about 1 in 10 reported physical victimization. Significant sex differences were found (OR = .29, CI = 0.08, 1.00), with males being less likely than females to report "any violence." Of six other sociodemographic characteristics examined, importance of religion (OR = .27, CI = 0.07-1.07) and school size (OR = .32, CI = 0.09-1.11) were associated with victimization at the p < .10 level. Adolescents who reported that religion was important to them and adolescents who attended larger schools were at lower risk of "any violence." CONCLUSIONS: As with opposite-sex relationships, psychological and minor physical violence victimization is common among adolescents involved in same-sex intimate relationships. Males reporting exclusively same-sex relationships were less likely than females to report experiencing the violence behaviors examined.     

Intimate Partner Violence Among Economically Disadvantaged Young Adult Women: Associations With Adolescent Risk-Taking and Pregnancy Experiences

CONTEXT: Intimate partner violence negatively impacts the health of substantial proportions of young women in economically disadvantaged communities, where sexual initiation, aggressive behaviors, unintended pregnancies and childbearing are common among adolescents. It is therefore important to assess how adolescent risk behaviors and pregnancy experiences are linked to such violence during young adulthood.
METHODS: Data from 526 participants in the Reach for Health Longitudinal Study who were surveyed during middle school (in 1995–1996 and 1996–1997) and at ages 22–25 (in 2005–2007) provided information on adolescent risk behaviors and pregnancy experiences, as well as experiences of intimate partner violence during young adulthood. Bivariate and multivariate analyses were conducted to identify correlates of intimate partner violence involvement.
RESULTS: As young adults, 29% of women reported having been victims of intimate partner violence in the past 12 months; 21% reported having perpetrated such violence. In multivariate analyses, victimization and perpetration in the last year are positively associated with aggressive behavior in middle school (odds ratios, 1.9 and 2.5, respectively), lifetime number of sex partners (1.3 for both) and having a history of unintended pregnancy or pregnancy problems (1.3 for both). Perpetration also is associated with early sexual initiation (0.5) and living with a partner (1.8).
CONCLUSIONS: It is important to consider women's pregnancy histories in programs aimed at preventing the adverse outcomes of relationship violence and in screening for partner violence in sexual and reproductive health services. Early intervention may help women develop the skills needed for resolving conflicts with peers and partners.     

Marital Infidelity and Intimate Partner Violence in Rural Malawi: A Dyadic Investigation

Extramarital sexual partnerships are a common reason for intimate partner violence (IPV) in sub-Saharan Africa. Despite the fact that IPV requires an interaction between two partners, the majority of the research focuses on individuals rather than the broader relationship context where such violence takes place. Using a sample of 422 married couples from rural Malawi, this study examined the dyadic environment of marital infidelity and two types of IPV victimization: sexual coercion and physical abuse. We considered both self-reported marital infidelity and perceived partner infidelity to assess how well partners knew each other and to compare their respective associations with IPV. Logistic regression was used to test for associations between self-reported marital infidelity and IPV. Multilevel logistic regression was used to examine actor and partner effects of perceived partner infidelity on an individual’s and their partner’s experience of IPV. The results show that self-reported marital infidelity was not significantly associated with IPV for men or women. However, the perception of a partner’s infidelity was significantly associated with both an individual’s and their partner’s risk for sexual coercion and physical abuse. Contrary to the “sexual double standard” hypothesis, women were not significantly more likely than men to report being physically abused when their partners suspected infidelity. Future studies should continue to explore the relationship context of IPV in sub-Saharan Africa in order to understand how spouses mutually shape each other’s experience of IPV and subsequent health outcomes.

An Exploration of Maternal Intimate Partner Violence Experiences and Infant General Health and Temperament

Objectives While the women’s health consequences of intimate partner violence have received much research attention, less is known about how maternal abuse experiences affect infant health and well-being. Existing studies have also been unable to examine specific types of intimate partner violence such as psychological aggression, physical abuse, and sexual coercion. This secondary data analysis explored the prevalence, patterns, and types of intimate partner violence within a large cohort of mothers and explored the relationship between maternal intimate partner violence experiences and infant’s general health and temperament at 1 year of age. Methods Existing data were drawn from the Fragile Families and Child Wellbeing study which collected data through surveys conducted shortly after the infant’s birth (baseline) and at 1 year of age (follow-up). Records from 4,141 mothers recruited from 75 hospitals, in 20 cities, in the US were used. Bivariate and multivariate regression analyses were conducted. Results Results show high rates of intimate partner violence. Maternal reports of any intimate partner violence at baseline or follow-up were both significantly associated with increased odds of less than excellent infant general health and difficult temperament. Independent examination of psychological, physical, and sexual abuse revealed differential relationships between the types of intimate partner violence and infant health outcomes. Conclusions Results from this study contribute to our understanding of the infant health threats associated with maternal intimate partner violence experiences. Additional research addressing the complex relationship between maternal abuse experiences and infant health and specific intervention implications is warranted.     

Sexual Coercion in Intimate Relationships: A Comparative Analysis of the Effects of Women’s Infidelity and Men’s Dominance and Control

Researchers studying the proximate (or immediate) causes of sexual coercion have proposed that partner rape is motivated by a man’s attempt to dominate and control his partner and that this expression of power is the product of men’s social roles. Researchers studying the ultimate (or evolutionary) causes, in contrast, have proposed that partner rape may function as an anti-cuckoldry tactic, with its occurrence related to a man’s suspicions of his partner’s sexual infidelity. In two studies, we collected data relevant to both perspectives to explore how these variables interact with men’s sexual coercion in an intimate relationship. Regression analyses from Study 1 (self-reports from 256 men) and Study 2 (partner-reports from 290 women) indicated that men’s sexual coercion of their partners was consistently predicted by female infidelity and men’s controlling behavior, suggesting that both variables are necessary to explain men’s sexual coercion. Discussion addressed limitations of the current research and highlighted the importance of integrating multiple levels of analysis when studying men’s sexual coercion of their intimate partners.     

Prevalence of intimate partner violence and related factors in a local city in Japan

OBJECTIVES: This study sought to assess the prevalence of intimate partner violence in a local city of Fukui Prefecture, and whether the subjects' and their partners' demographic characteristics, alcohol use, and violence experienced in the families in which they were raised might be related risk factors. METHODS: We conducted a mail survey of 1,000 subjects aged 20-69 in the city randomly sampled from the population of 45,220 that were stratified by 10 years of age and sex and pulled 100 from each group. Data from two 248 respondents were eligible for analysis. The self-administered questionnaire included items on; 1) whether they were the victims of physical, sexual, social-economic and psychological violence from their intimate partners, and whether they perpetrated violence or not on their partners; 2) demographic characteristics of the subjects and their partners with information on gender, age, occupation, educational background, annual income, the cohabitants, and their alcohol use; 3) the subjects' experience of violence in the family in which they had grown up; exposure to violence between their parents, and being abused by them. RESULTS: Out of 248 subjects, men accounted for 41.5%. The prevalence rate of any violence experienced from intimate partners was 46.4%, and that of having perpetrated any violence on the partner was 43.1%. Women reported experiencing more "sexual violence" from their partners than did men. In addition, men admitted to more "physical, sexual, and psychological violence" on their partners than women. Those who had themselves been exposed to violence between parents or were victimized by their parents significantly had more experience of violence from their partners and perpetration than those who did not. CONCLUSION: The results suggest that questioning about the experience of violence in the family is useful for the early detection of intimate partner violence.
