Childhood maltreatment and risk of intimate partner violence: A national study

ObjectivePrior research indicates that different types of childhood maltreatment frequently co-occur and confer risk for adulthood intimate partner violence (IPV). However, it is unknown whether the risk of IPV is due to specific type(s) of maltreatment or to their shared association or both. Although these competing explanations have different implications for intervention, they have never been evaluated empirically.MethodData were drawn from a nationally representative survey of 34,653 US adults, the 2004–2005 National Epidemiologic Survey on Alcohol and Related Conditions (NESARC). Structural equation modeling was used to simultaneously examine the shared and specific effects of five types of childhood maltreatment (i.e., sexual abuse, physical and emotional abuse and neglect) on the risk of different IPV behaviors (i.e., perpetration, victimization and reciprocal violence). Analyses were stratified by sex and adjusted for sociodemographic characteristics (i.e., age, personal income, educational background and race/ethnicity).ResultsMost types of childhood maltreatment increased the risk of victimization, perpetration and reciprocal violence. Effects of maltreatment types on each IPV behavior were exerted mostly through a latent factor representing the shared effect across all different types of maltreatment in both sexes (CFI = 0.990, TLI = 0.990, RMSEA = 0.023), although sexual abuse had an additional effect on victimization.ConclusionsBecause childhood maltreatment types increase the risk of each intimate partner violence behavior mainly through a general maltreatment dimension, underlying biological and developmental-ecological mechanisms should be considered important targets of prevention for both victimization and perpetration of abuse in adult relationships.     

The National Trajectory Project of Individuals Found Not Criminally Responsible on Account of Mental Disorder in Canada. Part 1: Context and Methods

The National Trajectory Project examined longitudinal data from a large sample of people found not criminally responsible on account of mental disorder (NCRMD) to assess the presence of provincial differences in the application of the law, to examine the characteristics of people with serious mental illness who come into conflict with the law and receive this verdict, and to investigate the trajectories of NCRMD–accused people as they traverse the mental health and criminal justice systems. Our paper describes the rationale for the National Trajectory Project and the methods used to collect data in Quebec, Ontario, and British Columbia, the 3 most populous provinces in Canada and the 3 provinces with the most people found NCRMD.

Women's status within the household as a determinant of maternal health care use in Nigeria

BackgroundAlthough gender inequality is often cited as a barrier to improving maternal health in sub-saharan Africa, there is lack of empirical data on how women''s socio-cultural characteristics may influence use of health services in Nigeria.ObjectiveTo describe how women''s position in the household affects receipt of maternity care services.MethodsSecondary data analysis of 10,052 and 4,590 currently married women aged 15 to 49 years from the 2008 Nigerian DHS who receive skilled antenatal and delivery care at least till pregnancy was done.ResultsReceipt of skilled delivery care was by 37.9% while, natal care was by 98.4%. Education, residence and wealth index all significantly influenced receipt of maternal health care. Women who were involved in decision making on their own health (aOR=1.97; 95%CI=1.88–2.06) and were employed throughout the year (aOR=1.11; 95%CI=1.01–1.23) were more likely to receive skilled antenatal care, while those who justified physical intimate partner violence were less likely to receive both skilled antenatal care (aOR=0.92; 95%CI=0.85–0.98) and delivery services (aOR 0.54; 95% CI 0.33–0.87).ConclusionInterventions aimed at improving maternal care should promote women empowerment (decision making, self worth, educational and economic) and should involve partners.     

新疆天山,阿尔泰山山地森林脑炎自然疫源地考察报告

1964～1966年我们考察了位于新疆天山山脉的15个县的林区及阿尔泰山山脉的3个县的林区,发现全沟硬蜱(Ixodes persulcatus)分布于海拔1500～1800m的森林草原景观中。并从天格尔山北坡的乌鲁木齐(N43°33′,E87°07′)、昌吉县林区(N43°30′,E86°55′),依连哈比尔尕山北坡的玛纳斯(N43°53′,E86°06′)、沙湾县林区(N43°56′,E85°12′),婆罗克努山南坡的尼勒克县林区(N44°02′,E82°38′),科古琴山南坡的霍城县林区(N44°28′,E81°10′),那拉提山北坡的新源(N43°16′,E84°01′)、巩留县林区(N43°11′,E82°44′)和哈尔克山北坡的特克斯(N43°59′,E81°55′)、昭苏县林区(N42°48′,E80°35′)采集的全沟硬蜱分离出森林脑炎病毒(Tick-borne encephalitis flavivirus)。从而判定上述地区存在森林脑炎自然疫源地。全沟硬蜱为主要媒介,其带毒率介于14.3％～47.7％。狍(Capreolus capreolus)、狐(Vulpes vulpes)、灰旱獭(Marmotabaibacina)、牛、马和羊均可作为该蜱的天然饲养者,从它们的血清中均检出森林脑炎病毒中和抗体。在疫源地内有散发病例发生。查布察尔(N43°34′,E81°08′、哈巴河(N48°28′,E86°42′)、奇台(N43°38′,E89°42′)、吉木萨尔(N43°49′,E89°)因采集材料过少尚不能确定     

Untangling serially dependent underreported count data for gender-based violence

Underreporting in gender-based violence data is a worldwide problem leading to the underestimation of the magnitude of this social and public health concern. This problem deteriorates the data quality, providing poor and biased results that lead society to misunderstand the actual scope of this domestic violence issue. The present work proposes time series models for underreported counts based on a latent integer autoregressive of order 1 time series with Poisson distributed innovations and a latent underreporting binary state, that is, a first-order Markov chain. Relevant theoretical properties of the models are derived, and the moment-based and maximum-based methods are presented for parameter estimation. The new time series models are applied to the quarterly complaints of domestic violence against women recorded in some judicial districts of Galicia (Spain) between 2007 and 2017. The models allow quantifying the degree of underreporting. A comprehensive discussion is presented, studying how the frequency and intensity of underreporting in this public health concern are related to some interesting socioeconomic and health indicators of the provinces of Galicia (Spain).     

Overlapping intimate partner violence and sex trading among high-risk women: Implications for practice

Despite research indicating higher than average rates of intimate partner violence (IPV) across groups of vulnerable women, less is known about the prevalence and types of IPV experienced by women who trade sex for money, drugs, shelter or food, a high risk group for poor health and psychosocial outcomes. Using a cross-sectional design and multivariate logistic regression analyses, this study examined the relationship between IPV and sex trading in a convenience sample of 346 HIV-negative, drug-involved women in relationships, recruited during 2005–2010 in New York City. About 41% and 36% of participants reported lifetime and recent IPV, respectively, by their main partner, with significant differences by recent engagement in sex trading (p < 0.01). Results of multivariate analyses indicated that sex trading was associated with recent severe physical or sexual IPV (OR = 3.07, p < 0.01) and that depression, having ever been married, child sexual abuse, and income were associated with IPV (p < 0.05). Women who reported childhood sexual abuse and recent sex trading had a 7.37 higher odds (p < 0.01) for reporting severe physical or sexual IPV compared to those who reported neither. Findings highlight the need to expand screening and interventions among women who trade sex.     

Economic solvency in the context of violence against women: a concept analysis

The aim of this concept analysis is to define economic solvency in the context of violence against women. Poverty, or lack of resources, is often discussed as a risk factor for intimate partner violence. The concept of economic solvency, which may be a protective factor for women, is less often discussed and not well defined. Databases searched for the analysis included EBSCOhost, CINAHL, PubMed and Gender Watch. The Rodgers evolutionary method was used to perform the concept analysis. A total of 134 articles were retrieved, using the specified search terms ‘economic solvency and women’, ‘economic self‐reliance and women’ and ‘economic self‐sufficiency and women’. Articles were included if they were peer reviewed, contained the keywords with sufficient context to determine the author's intended meaning, and focused on women only or contrasted men to women. Thirty‐five articles were used in the concept analysis. The definition of economic solvency drawn from the concept analysis is: a long‐term state that occurs when there is societal structure that supports gender equity and external resources are available and can be used by a woman who has necessary human capital, sustainable employment and independence. Just as poverty and violence are cyclical, so are economic solvency and empowerment of women. To decrease women's risk of intimate partner violence around the world and further improve the status of women, we recommend continued research on economic solvency, including the individual, family, community and societal resources required to obtain economic solvency and the human capital characteristics needed for sustainability.     

Conflict resolution patterns and violence perpetration in adolescent couples: A gender-sensitive mixed-methods approach

This study used a sequential two-phase explanatory design. The first phase of this mixed-methods design aimed to explore conflict resolution strategies in adolescent dating couples, and the second phase to document, from both the perspective of the individual and of the couple, dyadic interaction patterns distinguishing youth inflicting dating violence from those who do not. A sample of 39 heterosexual couples (mean age 17.8 years) participated in semi-structured interviews and were observed during a 45 min dyadic interaction. At phase 1, qualitative analysis revealed three main types of conflict resolution strategies: 1) negotiating expectations and individual needs; 2) avoiding conflicts or their resolution; 3) imposing personal needs and rules through the use of violence. At phase 2, we focused on couples with conflictive patterns. Results indicate that couples who inflict violence differ from nonviolent couples by their tendency to experience conflicts when in disagreement and to resort to negative affects as a resolution strategy. In addition, while at an individual level, they show a tendency to withdraw from conflict and to use less positive affect, at a dyadic level they present less symmetry. Results offer important insights for prevention programs.
