ACEs and mental health problems as suicidality predictors in Mexican adolescents

BACKGROUND

Various factors, including mental health comorbidity, family dysfunction, interpersonal violence, and community and social violence, cause suicidal behavior. Adverse Childhood Experiences (ACEs) encompass these risk factors and are correlated with mental health problems and suicidal behavior in Mexican adolescents.

METHODS

A survey was conducted among Mexican school-aged adolescents to measure ACEs, MHP symptoms, and suicidal behavior. A binary logistic regression was used to examine the relationship between these variables. The study was conducted with IRB approval, and all participants provided informed consent. Those at risk of suicide were referred for online psychological care.

RESULTS

7325 adolescents participated; 60 % were women, with an average age of 16 years (SD + 1), 87 % of the participants reported at least one ACE, 13 % symptoms of at least one MHP and 10 % suicidal behavior. MHP predictors of suicidal behavior were: conduct problems (OR = 5.67), symptoms of depression (OR = 3.27), obsessive-compulsive disorder (OR = 2.11), somatic problems (OR = 1.98), and attention deficit (OR = 1.69). EAI predictors were: live sexual violence (OR = 2.53), physical violence (OR = 2.21), negligence (OR = 2.05), bullying (OR = 2.10), and a family member with a mental health diagnosis (OR = 1.35). The cumulative effect of ACEs and MHP significantly increased the risk (OR = 78.08).

CONCLUSIONS

5 ACEs and 4 MHP were associated with suicidal behavior; their cumulative effect increased the risk to 78 times.

ACE-IQ extended version validation and ACE's frequency in Mexican adolescents

BACKGROUND

Adverse Childhood Experiences (ACEs) may have short, middle, and long-term consequences on people's development and physical and mental health. There is a need for information on this subject in low- and middle-income countries and a need to reduce recall bias in ACEs research worldwide.

OBJECTIVE

Hence our objectives were to translate, adapt and validate the Adverse Childhood Experiences extended version and to determine ACEs frequencies in a sample of Mexican adolescents.

PARTICIPANTS AND SETTING

A convenience sample of 5835 schooled Mexican adolescents (age: M = 16.13, SD = 1.32; 61.01 % females) from 20 states in Mexico completed a survey.

METHOD

A cross-sectional study was conducted with an extended version of the ACE-International Questionnaire (ACE-IQ), which assesses 23 ACEs organized into five categories: situations that cause household dysfunction, exposure to violence, violence from parents or guardians, interpersonal violence, and sociodemographic context.

RESULTS

Evidence of construct validity and reliability of the questionnaire was obtained, and 16 ACEs were included in the final ACE-IQ version. 90 % of adolescents had one or more ACEs. Neglect was the most experienced ACE reported by 73.30 % of the participants, with no significant difference by age, sex, or geographic region.

CONCLUSION

ACE-IQ questionnaire is a reliable and valid instrument to recommend its use for generating information on ACEs in studies on Mexican adolescents. The results on the frequency of ACEs revealed that 90 % of this schooled Mexican adolescent sample had experienced one or more ACEs, and about a third had experienced six or more.

Reprint of: Associations between mental health problems and Adverse Childhood Experiences ACEs in indigenous and non-indigenous Mexican adolescents

BACKGROUND

Adverse Childhood Experiences (ACEs) have long-term consequences. The ACEs model has been extensively used in high-income countries. However, its effectiveness has yet to be demonstrated in low and middle-income countries and marginalized social groups. In indigenous populations, research has found inconsistent results in the prevalence and the relationship between ACEs and mental health outcomes. Therefore, the objectives of this study were 1) to determine the ACEs frequency among indigenous and non-indigenous Mexican adolescents; 2) to test the association between ACE scores and symptoms of Mental Health Problems (SMHP) in both groups; and 3) to review the ACEs model adequacy for the indigenous adolescents.

PARTICIPANTS AND SETTINGS

Data from an online survey in 20 of the 32 states of Mexico were analyzed. We selected an 87 adolescent sample from indigenous families and 174 non-indigenous matched for age, sex, and state of residence, with a mean age of 16 years; 60 % were women.

METHODS

ACE-IQ questionnaire and Youth Self Report instrument (eight SMHP) were used to collect data. ACEs' frequency was analyzed for each group, and Pearson correlations were used to identify the relationship between ACEs and SMHP.

RESULTS

There was no statistical significance between Indigenous and non-Indigenous adolescents in the ACEs report. ACE scores were associated with eight SMHP. Correlations between ACE score and SMHP were higher in non-indigenous adolescents.

CONCLUSIONS

ACEs were experienced similarly by both groups and were associated with mental health in all participants. Further research is needed to improve ACEs measurement in indigenous populations.

Reuse and recycle solutions in refineries by ozone-based advanced oxidation processes: A statistical approach

Fresh water sources are under pressure globally by the increasing population and consequently increasing production, which increases the water demand day by day. Thus, decreasing the industrial fresh water demand and wastewater production became crucial both for the water availability in the future and for its impact to the environment. This study examined the ozone-based treatments as the possible solution to a refinery to treat the effluent already treated by the traditional techniques to reach the final requirements for reuse and recycle purposes. The screening tests performed by fractional factorial design revealed that the significant parameters for the treatment were ozone feed ratio, H₂O₂ amount and processing time while pH was found insignificant for this case. Based on the box-Behnken response surface methodology for effluent collected after biological treatment, the significant parameters were optimized as the ozone ratio of 0.9 g/h, H₂O₂ amount of 47 mg/L and 60 min duration. However, in case of increasing the H₂O₂ amount to 80 mg/L the duration can be minimized to 37.5 min decreasing the energy and reagent consumption costs by a 37%, reaching a final total organic carbon (TOC) under 4 mg/L, that is the target for reuse possibilities.
