Introduction In the international context, Mexico is a country with low drug use level, in turn, it shows an increase when considering the most recent epidemiologic trends. In order to maintain an updated analysis of drug use in general population and to identify the most at risk groups, the National Survey of Addictions (ENA) was held in 2011. Objetive The aim of the study was to determine the lifetime prevalence for any drug and any illegal drug use at a national and regional level, in population aged 12 to 65 years. Also, to acknowledge drug consumption trends since 2002 in Mexico. Material and methods ENA 2011 survey is a randomized, multistage probabilistic study. It is representative at a national level and also for eight regions of the country, including rural and urban population. The sample was 3 849 adolescents and 12 400 adults who answered a computerized version of a standardized questionnaire containing sections of tobacco, alcohol, medical drugs (opiates, tranquilizers, sedatives, amphetamines) and illegal drugs (marijuana, cocaine, crack, hallucinogens, inhalants, heroin and methamphetamines). All participants read and signed an informed consent. Emphasis was made on the voluntary and confidential use of the information. Results The national lifetime prevalence of any drug grew between 2002 and 2011, increasing significantly from 5.0% to 7.8%, while consumption of any illegal drugs increased from 4.1% to 7.2%. By sex, in men, any drug use increased from 8.6% to 13%. Illegal drugs increased from 8.0% to 12.5%. In women, use of any drug increased from 2.1% to 3.0% and use of any illegal drug increased from 1.0% to 2.3%. Marijuana is the first drug of choice (6.5%) followed by cocaine (3.6%). Considering regions, any drug consumption grew significantly in the Western (5.5% to 10.3%), Northeast (5.5% to 10.3%), North Central (7.5% to 9.2%) and South Central (4.2% to 7.5%). As for illegal drugs, there is also a statistically significant increase in these regions, however, growth was proportionally bigger in South Central region, going from 3.5% to 6.8%. Conclusions Results from this study indicate a growth in the consumption of illegal drugs from 2002 to 2011, especially in marijuana. It also shows that men from 18 to 34 years are the most affected by this consumption, while increases in adolescent men have been low. Moreover, the study shows that those who have received some type of prevention, showed a smaller consumption prevalence, indicating that further work is needed in this area with young people to consolidate activities of health promotion and drug use prevention, working with infant population is needed, including a systematic evaluation of the actions mentioned above. In the international context, data from this study confirms that Mexico continues reporting low levels of drug consumption.

The regional distribution of depressive symptomatology in women indicates the need for region-specific prevention programs that take into account the different social problems that affect women's emotional well-being. More research is also needed to support the early identification and intervention of men suffering from depression.

Introduction. Although the international literature suggests that women who interrupt a pregnancy in safe conditions do not develop mental health problems, it continues to be a highly stigmatized issue by broad social sectors. It is therefore not surprising that abortion stigma is one of the main factors associated with the presence of mental health problems in women who abort voluntarily. This study explores the association between perceived abortion stigma and depressive symptomatology. Method. In a non-probabilistic convenience sample, 114 users of a Legal Interruption of Pregnancy Clinic in Mexico City were interviewed with a structured instrument. Results. Respondents obtained low scores of internalized stigma and reported feeling confident that they had made the right decision to terminate their pregnancies, and at peace with themselves. The highest scores for abortion stigma were reported in the group with high depressive symptomatology, with no statistically significant differences being observed due to the sociodemographic characteristics explored. The participants in this study were more concerned about what others might think about their decision to terminate a pregnancy and about how their abortion might affect their relationship with them. Discussion and conclusion. These concerns highlight the need to reduce the negative social stigma surrounding abortion and to provide interventions in the same direction among women who interrupt a pregnancy legally in order to reduce the risk of mental health problems such as depression.

Introduction: Scientific evidence from the United States and European countries shows that women who have had an induced abortion are not more likely to become depressed and several factors may confound this outcome. In contrast, in the case of Latin America, there are practically no studies in this regard due to restrictive legislation prevailing in the region. This paper aims to determine the prevalence of a probable major depressive episode (PMDE) in women who have legally terminated a pregnancy by way of public service in Mexico City and whether there are any psychosocial factors reported by the international literature associated with this outcome. Method: In a cross-sectional study, 274 women aged 15 years or older were interviewed two weeks after undergoing a medical abortion between November 2018 and November 2019. The Center for Epidemiological Studies Depression Scale 35-item version (CESD-R35) was used to measure the PMDE in a structured interview. Results: The prevalence of a PMDE was 15.8%. Multivariate logistic regression was used for adjusted analysis. Perceived abortion stigma (OR = 6.74, 95% CI = 3.29-13.82), child sexual abuse (OR = 2.23, 95% CI = 1.01-4.93), and previous childless pregnancies (OR = 6.07, 95% CI = 1.52-24.21) were associated with PMDE. Conclusions: The prevalence of PMDE is similar to or lower than that reported in studies with women who continued a pregnancy; post-abortion counseling and clinical considerations should include the impact that stigma and gender-based violence have on women’s mental health.

Introduction. Research findings about intimate-partner violence (IPV) have focused mostly on women as victims of violence. Recent studies show the importance of violence inflicted by women towards men or between same-sex couples. Objective. To estimate the prevalence of intimate-partner violence and its association with alcohol and drug consumption in a representative sample of men and women in Mexico through secondary data analysis. Method. The data come from a representative sample who filled out the section on intimate-partner violence in the Mexican 2011 Encuesta Nacional de Adicciones (National Survey on Addictions). Results. The prevalence of intimate-partner violence in the last year was 17.6% against women and 13.4% against men. If one of the two partners consumed substances, the risk that men and women would experience violence increased, and that risk was even greater if both consumed. Discussion and conclusion. This is the first time violence against men was reported in a Mexican national study. The findings show that gender-based violence should also be considered a result of social and cultural violence.
