Objective: To study the problem.tic use of video gam.s am.ng secondary school students in the city of Parakou in 2023. m.thods: Descriptive cross-sectional study conducted in the com.une of Parakou from.Decem.er 2022 to July 2023. The study population consisted of students regularly enrolled in public and private secondary schools in the city of Parakou for the 2022-2023 academ.c year. A two-stage non-proportional stratified sam.ling technique com.ined with sim.le random.sam.ling was adopted. The Problem.Video Gam. Playing (PVP) scale was used to assess problem.gam.ling in the study population, while anxiety and depression were assessed using the Hospital Anxiety and Depression Scale (HADS). Results: A total of 1030 students were included. The m.an age of the pupils surveyed was 15.06 ± 2.68 years, with extrem.s of 10 and 28 years. The [13 - 18] age group was the m.st represented, with a proportion of 59.6% (614) in the general population. Fem.les predom.nated, at 52.8% (544), with a sex ratio of 0.89. The prevalence of problem.tic video gam. use was 24.9%, m.asured using the Video Gam. Playing scale. Associated factors were m.le gender (p = 0.005), pocket m.ney under 10,000 cfa (p = 0.001) and between 20,000 - 90,000 cfa (p = 0.030), addictive fam.ly behavior (p m.nogam.us fam.ly (p = 0.023), good relationship with father (p = 0.020), organization of video gam. com.etitions (p = 0.001) and definite anxiety (p Conclusion: Substance-free addiction is struggling to attract the attention it deserves, as it did in its infancy everywhere else. This study com.lem.nts existing data and serves as a rem.nder of the need to focus on this group of addictions, whose problem.tic use of video gam.s rem.ins the m.st frequent due to its accessibility and social tolerance. Preventive action com.ined with curative m.asures rem.ins the m.st effective m.ans of com.ating the problem.at national level.

植物的生态过程依赖于叶片和根系的功能运行,但少有研究同时关注这两类性状在群落中的分布格局(CTD)。本文测定了广东亚热带森林44种共生木本植物的16个叶片和根系性状,旨在检验类比的叶片和根系性状是否耦合,是否沿类似的功能性状谱变异,是否表现出类似的CTD,其CTD和群落加权平均性状值(CWm.是否沿环境梯度表现出类似的响应。研究结果表明,叶片和根系性状变异的第一轴均呈显出由资源获取向资源保守变异的经济学谱,但叶片变异的第二轴主要由叶片碳含量表征,而根系变异的第二轴主要由反映菌根协作程度的根系粗细表征。类比的叶片和根系化学性状整体正相关,但形态性状的耦合程度较低。在群落水平上,叶片和根系性状第一轴的CWm.随海拔升高而变得更保守,而第二轴的变化则不一致。随土壤磷含量的降低或钾含量的升高,根系变得更细和在养分性状上更保守,而叶片性状无显著变化。当整合多维性状轴时,叶片性状呈发散格局,且随海拔、土壤磷和钾含量的增加呈收敛趋势;而根系性状呈收敛格局,但沿上述环境梯度呈发散趋势。该研究强调,叶片和根系性状与环境互作的差异可能导致不同的性状分布格局;植物可通过多样的地上和地下功能设计应对环境异质性。

Introduction: Post-traum.tic stress disorder (PTSD) is defined as “actual exposure to death or the threat of death, serious injury or sexual violence”, either directly or indirectly, resulting in a sym.tom.tic procession of repetition, avoidance, neurovegetative hyperactivity and individualized sym.tom., with or without negative cognitive and m.od changes. It therefore goes without saying that the defence and security forces constitute a high-risk population in need of attention. Objective: To study post-traum.tic stress disorder in defence and security forces in the city of Parakou in 2023. m.thods: Descriptive cross-sectional study conducted from.Decem.er 2022 to July 2023. The study population consisted of active m.litary, republican police and firefighters in the city of Parakou in 2023. Non-proportional stratified sam.ling was used, given the inaccessibility of the source population size for national security reasons. Post-traum.tic stress disorder was assessed using the “post-traum.tic stress disorder checklist-5 (PCLS-5) scale. Results: A total of 305 subjects participated in the survey. m.les dom.nated 90.2%. The m.st represented corps was the Republican Police (41.6%), m.st of whom.were non-com.issioned officers (46.6%). The m.jority count between 11 and 20 years of service (48.9%), with 2 to 5 m.ssions com.leted (67.5%). The calculated prevalence of post-traum.tic stress disorder was 11.8%, based on the post-traum.tic stress disorder checklist-5 (PCL-5). Of the 36 respondents with post-traum.tic stress disorder, 20 (55.6%) had experienced an arm.d attack, 25 (69.4%) had witnessed a violent death, 18 (50.0%) had witnessed the agony of a colleague, 15 (41.7%) had been exposed to a fire or explosion, while 26 (72.2%) had been traum.tized by physical and/or verbal aggression. 5 (13.9%) had consulted a specialist psychiatrist, while 6 (16.7%) were on m.dication and 26 (72.2%) used sport as a m.ans of m.intaining physical and m.ntal health.

Introduction: From.their earliest hours, hum.n beings are able to identify a source of food and to feed them.elves. Feeding is therefore one of the m.st instinctive hum.n functions. It is regulated by several factors (physiological, psycho-affective and environm.ntal) whose disruption can lead to eating disorders. Objective: The aim.of this study was to investigate eating disorders am.ng students in the town of Parakou in 2023. m.thod: Descriptive cross-sectional study conducted from.January to July 2023 in various universities in the city of Parakou, Benin. The study population consisted of all students in grades 1 to 7 at these universities. A two-stage non-proportional stratified sam.ling technique com.ined with a sim.le random.draw was adopted. The Eating Attitude Test-26, Bulim.a Inventory Test Edinburgh and a set of questions focusing on the diagnostic criteria for pica were used to screen for pica and other disorders such as anorexia, bulim.a nervosa and binge eating disorder. Data were analyzed using SPSS (Statistical Package for Social Sciences) version 25. Results: A total of 607 students were surveyed, 323 of whom.had eating disorders. A prevalence of 53.21% of students at risk of eating disorders was found. In relation to the total population, the prevalences of anorexia, bulim.a nervosa, binge eating disorder and pica were 45.96%, 0.82%, 15.48% and 12.68% respectively. In m.ltivariate analysis, seven factors explained the risk to develop at least one eating disorder am.ng the students surveyed. These were: urban area of residence (OR (95% CI) = 5.059 (1.75 - 14.65);p = 0.003);year of study (OR (95% CI) = 0.47 (0.28 - 0.79);p = 0.035);type of university attended (private university: OR (95% CI) = 1.63 (1.08 - 2.44);p = 0.019);parents’ m.rital status (couple or not) (OR (95% CI) = 1.50 (1.01 - 2.24);p = 0.046);father’s level of education: secondary (OR (CI 95%) = 3.85 (1.96 - 7.54);p 0.001)/higher (OR (CI 95%) = 2.83 (1.36 - 5.86);p = 0.005);m.ther’s one:

Objective: The aim.of the present study was to investigate the psychic repercussions of sexual assault am.ng fem.le students in Parakou in 2023. m.thods: Descriptive cross-sectional study conducted from.Decem.er 2022 to July 2023 am.ng all students at the University of Parakou. The sam.ling technique was stratified non-proportional at two levels. The dependent variable was self-reported sexual assault. The psychopathological repercussions linked to sexual assault and explored in these students were: post-traum.tic stress disorder assessed with the Post Traum.tic Stress Disorder Checklist-5 (PCL-5) scale;and current depression screened with the Patient Health Questionnaire-9 (PHQ-9) scale. Results: A total of 376 fem.le students from.the University of Parakou m.eting the inclusion criteria were surveyed. The average age of the subjects surveyed was 20.56 ± 2.46 years, with extrem.s of 16 and 32 years. A predom.nance of subjects under 25 was observed. The prevalence of sexual assault am.ng fem.le students at the University of Parakou was 10.63%. The types of aggression suffered were m.stly rape (18 people;45%) and sexual touching (16 people;40%), and the aggressors were m.inly friends/boyfriends (13;32.5%), fam.ly m.m.ers (12;30.0%) and people from.the house/neighborhood (9;22.5%). Psychological repercussions included depression in 72.5% (29) of cases, with m.ld depression in 30% (12), m.derate depression in 37.5% (15) and severe depression in 5% (2). Anxiety disorders were present in 27.50% (11) of victim.. The risk factors associated with sexual assault in these students were gravidity (p = 0.014;OR = 15.32), unhappy life events (p = 0.01;OR = 17.24), and age of first sexual intercourse (p = 0.016;OR = 4.608).

Introduction: Also known as m.ternal burnout syndrom., m.ternal burnout is a state of physical, em.tional and m.ntal exhaustion generated by prolonged stress in the fam.ly environm.nt. It is experienced by wom.n in their role as m.thers. Those affected can develop psychological disorders, sleep disturbances, etc., all of which im.air their day-to-day lives, and thus their m.ternal role. The repercussions affect both the child and other fam.ly m.m.ers. Objective: The aim.of the present study was to investigate m.ternal burnout am.ng fem.le users of public and private health facilities in the com.une of Parakou in 2023. m.thods: Descriptive cross-sectional study was conducted from.Decem.er 2022 to July 2023 am.ng all m.thers using public and private health facilities in the com.une of Parakou. All healthy m.thers with at least one biological or adoptive child fully dependent on them.and living at hom., who cam. for a consultation in one of the health facilities or for an appointm.nt at the Expanded Program.on Im.unization (EPI) and gave their free and inform.d consent. Sam.ling was done for non-exhaustive convenience were included in the study. Burnout was assessed using the Parental Burnout Assessm.nt (PBA) scale. Results: A total of 888 m.thers m.eting the inclusion criteria were surveyed. The prevalence of burnout calculated using the Parental Burnout Assessm.nt (PBA) scale was 6.19%. The risk factors for m.ternal burnout were poor relationships with fam.ly and friends (OR = 8.90;p = 0.045), m.derate (OR = 11.71;p = 0.020) and severe depression (OR = 40.85;p = 0.001), followed by the presence of repeated nocturnal awakening (OR = 5.14;p = 0.014). Conclusion: This is a subject that is alm.st never discussed in African society, but whose reality is revealed by the present study, which provided statistical data on m.ternal burnout. From.now on, the risk of burnout will no longer be discussed solely in the fam.ly context. It will also need to be explored within the fam
