AI Article Synopsis
- The study aims to explore the brain structure differences between child sexual offenders and non-offenders, separating the effects related to pedophilia to understand the broader implications for child sexual offending.
- Using structural MRI data from incarcerated males, the research compares gray matter in two groups of child sexual offenders (pedophilic and non-pedophilic) and violent non-sexual offenders.
- Findings reveal reduced gray matter in various brain regions, including the cerebellum and frontal lobe, suggesting possible structural abnormalities linked to child sexual offending, beyond just pedophilia.
Article Abstract
Aim: To further investigate the neuroanatomical correlates of child sexual offending and disentangle them from the neural correlates of pedophilia, using a multivariate analytical approach in order to minimize loss of statistical power.
Methods: This study presents structural MRI data on gray matter in an incarcerated, male population of 22 pedophilic and 21 non-pedophilic child sexual offenders, and 20 violent non-sexual offender controls, based on a multivariate whole-brain approach using source-based morphometry.
Results: We identify a network of several neuroanatomical regions exhibiting interrelated reduced gray matter in both child sexual offender groups relative to controls, comprising extensive clusters in the bilateral cerebellum and frontal lobe, as well as smaller clusters in the bilateral parietal, temporal, and occipital lobes, the bilateral basal ganglia, the medial cingulate and the hippocampus.
Conclusion: Our results speak to the interpretation that there are inter- and possibly connectivity-related brain structural abnormalities in child sexual offenders that are not (only) pertaining to pedophilia per se. Interpretations and limitations of the present data are discussed and recommendations for future works are given.

The Change in Child Sexual Abuse Victimization Among Chinese Children and Adolescents (2000-2022): A Cross-Temporal Meta-Analysis.

Sichuan University, Chengdu, China.
Limited meta-analytical research has examined the epidemiology of child sexual abuse (CSA) victimization among Chinese children and adolescents over the past two decades. It is crucial to evaluate how the incidence of CSA has changed over time in response to the significant policy and sociocultural changes since 2013. This study employed a cross-temporal meta-analysis to explore the trend of CSA victimization among Chinese children and adolescents from 2000 to 2022.

Central precocious puberty (CPP) is an endocrine disease in children, characterized by rapid genital development and secondary sexual characteristics before the age of eight in girls and nine in boys. The premature activation of the hypothalamic-pituitary-gonadal axis (HPGA) limits the height of patients in adulthood and is associated with a higher risk of breast cancer. How to prevent and improve the prognosis of CPP is an important problem.

Background: There is currently limited research exploring the extent to which women with an intellectual disability experience autonomy over contraception, pregnancy timing and pregnancy outcome decisions. Previous studies have highlighted inequities in sexual and reproductive health outcomes. However, barriers and facilitators of reproductive autonomy for women with an intellectual disability across the reproductive journey, including health care experiences, are poorly described; this is the focus of the current study.

Background: Mammalian cells possess molecular clocks, the adequate functioning of which is decisive for metabolic health. Exercise is known to modulate these clocks, potentially having distinct effects on metabolism depending on the time of day. This study aimed to investigate the impact of morning vs.

Background: Community acceptance of Traditional birth attendants (TBAs) as professional birth attendant was reported as one of the bottlenecks that has been hindering facility childbirth care service use. Hence, the World Health Organization (WHO) recommended that all childbirths needed to be attended by professional skilled attendants who at least possessed midwifery skill through the safe motherhood initiative. However, many births in developing countries have been being attended by Traditional birth attendants (TBAs) mainly due to pregnant women and community acceptance for TBAs as sole birth attendants.
