This study measured the prevalence of cases of domestic violence against women and some associated factors during the COVID-19 pandemic in Mexico. Data were collected through a remote survey during 2020. The sample included 47,819 women aged 15 years and older. Jointpoint regression and logistic regression models were used. The prevalence of violence was 11.5%, which decreased in July and subsequently increased. The associated factors were being unemployed (OR = 2.01; 95%CI 1.89–2.16); being partially and totally quarantined (OR = 1.58; 95%CI 1.43–1.75 and OR = 1.47; 95%CI 1.32–1.63); being a caregiver of children; being a caregiver of elderly and/or suffering from a chronic illness (OR = 1.27; 95%CI 1.19–1.36; OR = 1.42; 95%CI 1.33–1.53; OR = 1.59; 95%CI 1.47–1.73); losing a family member to COVID-19 (OR = 1.26; 95%CI 1.13–1.41); and binge drinking (OR = 1.94; 95%CI 1.78–2.12). The confinement measures increased gender inequalities, economic problems and workload which further evidenced violence against women.

Objetivo. Conocer la magnitud del consumo excesivo de alcohol (CEA) y su asociación con los factores individuales, familiares y sociales entre agosto y noviembre de 2020 en México. Material y métodos. Con base en los datos de la Encuesta Nacional de Salud y Nutrición 2020 sobre Covid-19, se analizaron 8 595 adultos mayores de 20 años. Se estimaron modelos de regresión logística estratificados por sexo y se obtuvieron razones de momios (RM) con intervalos de confianza al 95% (IC95%). Resultados. El CEA fue de 40.43%; hombres 56.49% y mujeres 25.70%. Los principales factores asociados fueron ser hombre (RM=3.66; IC95%: 3.22,4.12), edad de 20 a 29 años (RM=3.65; IC95%: 2.89,4.63), salir a trabajar durante la pandemia (RM=1.56; IC95%: 1.33,1.81) y tener dos o más escolares en el hogar (RM=1.20; IC95%: 1.03,1.39). Conclusiones. En México, el patrón de CEA es prevalente; por su naturaleza de riesgo y su amplia distribución poblacional, es prioritario implementar intervenciones preventivas individuales y de salud pública.

Depression, suicidal behavior, excessive alcohol intake, and tobacco use are the main mental health problems in adolescents. To address these problems, it is necessary to understand the many factors associated with them, including parental factors. The aim of this study was to assess the associations between parental behavior and mental health problems in adolescents in Mexico. Data from the National Health and Nutrition Survey (ENSANUT) 2018–2019, representative for Mexico, were used. Households in which a parent–adolescent child pairing was identified (regardless of family type) were selected; n = 8758 households. The four outcomes of interest that were measured in the adolescents were: excessive alcohol intake, tobacco use, suicidal behavior, and depressive symptomatology. Logistic regression models using the adjusted odds ratio (AOR) and 95% confidence interval (95% CI) were estimated. Adolescents whose parents used alcohol or tobacco and reported depressive symptoms and suicidal behavior were more likely to present these behaviors themselves (AOR = 1.47, 95% CI: 1.17–1.85; AOR = 2.26, 95% CI: 1.51–3.39; AOR = 2.61, 95% CI: 1.88–3.61; AOR = 1.74, 95% CI: 1.16–2.61, respectively). Child sexual abuse was also strongly associated with the four outcomes of interest in adolescents (AOR = 1.89, 95% CI: 1.06–3.36 for excessive alcohol intake; AOR = 2.97, 95% CI: 1.49–5.91 for tobacco use; AOR = 5.15, 95% CI: 3.27–8.09 for depressive symptoms; AOR = 6.71, 95% CI: 4.25–10.59 for suicidal behavior). The family constitutes the central nucleus of care for children and adolescents; therefore, any effort to promote adolescent mental health must necessarily involve their parents and family.

Background: Child Sexual Abuse (CSA) is a global social and health problem requiring a comprehensive, multi-level prevention approach. School-based education is recognized as one of the most effective prevention strategies. Objective: This project aims to test the effectiveness of the preventive intervention, “Pinta tu Raya ASI” (Set your Limit LIKE THIS), to prevent CSA. Methods: This is a two-arm matched cluster-randomized controlled trial of an educational intervention to prevent CSA in Mexican elementary school children using Immersive Virtual Reality (IVR). The study will be administered in clusters of public and private schools in urban and rural areas across two Mexican states. The intervention group will receive a learning session with an IVR animation, while the control group will receive the intervention only after the final knowledge acquisition measurement. Results: The project is expected to enhance elementary students’ knowledge of self-esteem, body safety, and rights to help them prevent child violence in Mexico. Ethics: The study was approved by the National Institute of Public Health’s Commissions of Research, Ethics, and Biosafety. Ethical safeguards include obtaining informed consent from guardians and assent from minors, providing trained staff, continuous monitoring during the IVR session, and having a specialized psychology team for case management and referral. Trial registration: The study was approved by the Commissions of Research, Ethics and Biosafety at the National Institute of Public Health: code CI: 1713 V47.

Background: Child sexual abuse (CSA) is a serious public health concern that violates the rights of children. In Mexico, little is known about the actual figures for this type of violence. Objective: This study aimed to determine trends in the prevalence and case characteristics of CSA in a representative sample of children in Mexico. Materials and Methods: Data from the National Health and Nutrition Survey (ENSANUT) for 2018, 2020, 2021, 2022 and 2023 were used (n = 24,179). Proportions of CSA were estimated using the weighted mean of a binary variable, and the variance of the estimated proportion was calculated using the Taylor linearization method. Logistic regression models were estimated, and Adjusted Odds Ratios (AORs) with 95% Confidence Intervals (95% CIs) were obtained. Results: The prevalence of CSA ranged from 2.22% (2018) to 5.66% (2023). There was an increasing trend in CSA between 2018 and 2021, which was even more pronounced (154.95%) between 2018 and 2023 (p < 0.001). The main perpetrator in CSA cases was a family member (78.51%), and most victims did not report the abuse to the authorities. Girls were more likely to experience CSA (AOR = 2.83, 95% CI: 1.72–4.68), and as years passed (from 2018 to 2023), the likelihood of becoming a victim of CSA increased. Conclusions: CSA is a problem that has increased in recent years in Mexico. It is noteworthy that the main perpetrator is within the family, which may influence the lack of reporting of these cases. In view of this situation, it is necessary to implement strategies to prevent CSA in children, involving mothers, fathers, and caregivers.
