La violencia doméstica en Medellín y demás municipios del Valle de Aburrá, 2003-2004
Duque,Luis F; Montoya,Nilton E;
Revista Facultad Nacional de Salud Pública , 2008,
Abstract: objective: to estimate the magnitude and distribution by sex of domestic or family violence (between partners, siblings, and from parents to children) in medellin, colombia and nine surrounding municipalities (medellin metropolitan area), 2003-2004. methods: household survey to a representative multistage sample to non institutionalized population, within 12 and 60 years of age, in the urban area of each municipality. results: verbal or psychological aggression and victimization: 64% and 61%, physical violence without physical injury: 17% and 14%, physical violence with physical injury: 2% and 3% between intimate partners. intimate partners? aggression and victimization do no differentiate by sex. verbal, psychological and physical aggression from parents toward children is 60%, and physical aggression with physical injury is near 10%. 55% of families reported fights among siblings, and 3% with physical injury. medellin has the highest rates of family or domestic violence compared with the other municipalities of aburra valley. domestic violence charge is very low (5-20%), and masculine victims rather prefer not to report. conclusions: we suggest not to ground public policies on current statistics, but to establish a system of periodic surveys, representative of general population or families. it seems important to have two different types of interventions: domestic or family violence prevention considering family as a unit that interacts with the surrounding; and rehabilitation of chronic and severe domestic aggressors.
Sistema de vigilancia epidemiológica de la violencia para los municipios colombianos
Duque,Luis F; Caicedo,Beatriz; Sierra,Clara;
Revista Facultad Nacional de Salud Pública , 2008,
Abstract: the different systems of epidemiological surveillance of injuries and violence proposed by colombian and international institutions are analyzed. the fact that those systems do not provide enough information on non fatal injuries, characteristics of the aggressors nor protection factors of the different forms of violence is emphasized. a system based on information which should be gathered at a small scale according to legal rules is proposed. this information should also be underreported (violent deaths, suicide, deaths due to traffic accidents, and non fatal injuries). the implementation of periodic and systematic community surveys is also suggested, designed in different formats according to the local circumstances of the municipalities. the magnitude and distribution of the different forms of violence and other risky behaviors generally linked to such violence, as well as the protection and risk factors are all monitored through the surveys mentioned above. the system proposed here does not replace the surveillance systems legally adopted by colombian norms, but it does reinforce and complement them.

Violence witnessing, perpetrating and victimization in medellin, Colombia: a random population survey
Luis F Duque, Nilton E Montoya, Alexandra Restrepo
BMC Public Health , 2011, DOI: 10.1186/1471-2458-11-628
Abstract: A face-to-face survey was carried out on a random selected, non-institutionalized population aged 12 to 60 years, with a response rate of 91% yielding 2,095 interview responses.We present the rates of prevalence for having been a witness, victim, or perpetrator for different forms of violence standardized using the WHO truncated population pyramid to allow for cross-national comparison. We also present data on verbal aggression, fraud and deception, yelling and heavy pranks, unarmed aggression during last year, and armed threat, other severe threats, robbery, armed physical aggression, and sexual aggression during the lifetime, by age, sex, marital and socioeconomic status, and education. Men reported the highest prevalence of being victims, perpetrators and witnesses in all forms of violence, except for robbery and sexual violence. The number of victims per perpetrator was positively correlated with the severity of the type of violence. The highest victimization proportions over the previous twelve months occurred among minors. Perpetrators are typically young unmarried males from lower socio-economic strata.Due to very low proportion of victimization report to authorities, periodic surveys should be included in systems for epidemiological monitoring of violence, not only of victimization but also for perpetrators. Victimization information allows quantifying the magnitude of different forms of violence, while data on factors associated with aggression and perpetrators are necessary to estimate risk and protective factors that are essential to sound policies for violence prevention formulation.Out of 1.6 million deaths that are caused by violence annually in the world, around 90% occur in developing countries [1]. Compared to developed countries, there is still scant empirical information on the magnitude and composition of interpersonal violence, which represents the most widespread type of violence in the world and has become a serious public health problem [2-4]

Duque,Luis F.; Klevens,Joanne; Montoya,Nilton E.;
Revista Facultad Nacional de Salud Pública , 2007,
Abstract: concurrent risky or deviant behaviors of serious offenders, resilient men and community controls were estimated through a case-control study carried out in medellin, colombia between 2003 and 2005. methodology: cases: serious offenders (n=62), men involved in violent quarrels or brawls (n=81), and members of autodefensas unidas de colombia -colombian paramilitary army- (auc), also known as paramilitaries (n=72) were compared to resilient men (n=59) and community controls (n=103). all were interviewed face to face in their communities. cases were interviewed at the site, day and hour agreed with the group leader. controls and resilient men were referred by respected and trusted persons of the community and interviewed in their own communities in a place chosen by them. results: antecedents of overt and covert aggression, deviant behaviors and oppositional behaviors, and substance abuse was higher among auc members (paramilitaries), serious offenders and men involved in quarrels than among community controls and resilient men. resilient men report a smaller number of concurrent deviant and risky behaviors compared to community controls. auc members (paramilitaries) are not different from serious offenders in their reports of concurrent risky and deviant behaviors.

Revista Facultad Nacional de Salud Pública , 2007,
Abstract: Concurrent risky or deviant behaviors of serious offenders, resilient men and community controls were estimated through a case-control study carried out in Medellin, Colombia between 2003 and 2005. Methodology: Cases: serious offenders (n=62), men involved in violent quarrels or brawls (n=81), and members of Autodefensas Unidas de Colombia –Colombian paramilitary army– (AUC), also known as paramilitaries (n=72) were compared to resilient men (n=59) and community controls (n=103). All were interviewed face to face in their communities. Cases were interviewed at the site, day and hour agreed with the group leader. Controls and resilient men were referred by respected and trusted persons of the community and interviewed in their own communities in a place chosen by them. Results: Antecedents of overt and covert aggression, deviant behaviors and oppositional behaviors, and substance abuse was higher among AUC members (paramilitaries), serious offenders and men involved in quarrels than among community controls and resilient men. Resilient men report a smaller number of concurrent deviant and risky behaviors compared to community controls. AUC members (paramilitaries) are not different from serious offenders in their reports of concurrent risky and deviant behaviors.
Similarities and differences among paramilitaries, severe aggressors and communal control, a case-control study in Medellín, Colombia

Revista Facultad Nacional de Salud Pública , 2007,
Abstract: A case-control study was performed in Medellín during 2003-2004 to compare characteristics of severe aggressors, members of Colombian United Selfdefense Forces members (AUC), otherwise named paramilitaries, and communal control. Severe aggressors and paramilitaries have lower educational level than communal control; their families were biparental in a lower proportion, and experienced drug and alcohol abuse in a higher proportion than in the case of families of communal control. Severe aggressors and paramilitaries’ families suffered forced displacement and assassination of one of its members in a higher proportion than those of controls. There were no differences relating time of residence in Medellín or current neighborhood, or current family socioeconomic stressors. No differences were found regarding believing in God, religious practice and reasons for practicing religion. There were no signi cant differences for all mentioned variables between severe aggressors and paramilitaries. Paramilitaries did inform having suffered extreme poverty conditions during childhood in a higher proportion than severe aggressors and controls. Progress opportunities perception was also explored.

Abstract: blood plasma from six different non pregnant and pregnant species, including human blood plasma, was analyzed for detection of α2-macroglobulin (α2-m). the tropical hair sheep (ovis aries) and the buffalo (bubalus bubalis) were studied for the first time in colombia. the presence of the α2-m in plasma of all the species was demonstrated by sds 7.5% page as bands of 180 kda as well as by non-denaturing 5% page with bands of 720 kda. the tetrameric form α2-m (tetramérica) and the pregnancy zone protein (pzp) (dimeric) purified at 98%, as well as its corresponding bans from human plasma were used as control. the n-terminal sequence of the band of 180 kda in tropical hair sheep plasma was very similar to the purified human α2-m. the results indicated the presence of α2-m in blood plasma of all the species tested, while the pzp was present only in the pregnant human plasma. both human and bovine α2-m became activated with the fast form by reacting with methylamine. this fac. demonstrates the differences in the reactivity of the animal’s α2-m with primary amine as compared with the human α2-m. it could be necessary to unify purification methods into one method for all species, so that the sensitive domain of the α-macroglobulins (thiolester and bait region) receives the same treatment and grade of denaturation for all α2-m preparation.

Abstract: A través del presente estudio se analizaron plasmas sanguíneos de seis especies, incluyendo el humano tanto en estado gestante como no gestante, identificándose por primera vez en plasma, la glicoproteína α2-Macroglobulina (α2-M) de ovino de pelo (Ovis aries) y de búfalo (Bubalus bubalis). La presencia de esta proteína en el plasma sanguíneo de todas las especies en estudio se demostró mediante electroforesis en gel de poliacrilamida usando sodio dodecilsulfato como agente denaturante (SDS PAGE) al 7.5% identificándose como bandas de 180 kDa y en forma no denaturante PAGE 5% como bandas de 720 kDa. Estas últimas bandas fueron claramente intercambiables de la forma tetramérica a la forma monomérica en los ensayos electroforéticos. Como controles se usaron la α2-M (tetramérica) y la proteína de la zona de gestación (PZP) (dimérica) purificadas a un 98%; así como, las bandas de estas dos proteínas en el plasma humano. El análisis de la secuencia del dominio N-terminal de la (α2-M) de ovino de pelo, fue muy similar al de la proteína humana purificada. Tanto la α2-M humana como la bovina llegaron a ser activadas a la forma rápida por medio de la reacción con metilamina. Lo anterior demuestra diferencias en la reactividad de las α2-M animales con la amina primaria cuando se comparan los resultados con la forma rápida de la α2-M humana. Será necesario unificar los métodos de purificación de esta proteína en todas las especies, de tal manera que los dominios sensibles de las α-macroglobulinas (tioιster y región se uelo) tengan el mismo tratamiento y el mismo grado de desnaturalización para todas las preparaciones de α2-M.
