The influence of chromosomal sex on human diseases is recognized but underresearched, particularly in diseases with early developmental origins. Copy number variations (CNVs) from sex chromosomes or autosomes, which cause different gene expressions, may influence the disease preferences in females and males. Chromosomal microarray is a standard method for detecting CNVs, with a diagnostic yield of approximately 15 % among patients with congenital anomalies and neurodevelopmental disorders, the primary indications for the analysis. Here, we explore sex disparities in phenotype prevalence and CNV detection rates in patients referred for chromosomal microarray to identify sex-biased traits and CNVs. Our cohort comprises 1412 patients, with a male-to-female ratio of 1.6 to 1. Despite being outnumbered, females are significantly more likely to receive a genetic diagnosis through this type of molecular karyotyping. Most of the patients have neurodevelopmental disorders with other comorbidities. Females have a higher frequency of comorbidities, but the difference in diagnostic yield is significant only in the groups with simpler phenotypes (≤2 comorbidities). Higher diagnostic yield is revealed for congenital heart disease, urogenital anomalies, and the autism spectrum group. All three categories show populational preponderance in males, supporting a higher threshold liability model in females. © 2025 Elsevier B.V.

This study examined the association between social characteristics, substance use, and psychological distress in a national representative sample of adults in Serbia. It was a secondary analysis of the National Survey on Lifestyles in Serbia: Substance Abuse and Gambling 2018. The study included a total of 2000 participants aged 18 to 65 from the general population in Serbia. Psychological distress was examined using the Kessler 6 questionnaire. There were a total of 945 male participants (47.3%) and 1055 (52.8%) female participants. The average age was 37.83 ± 13.61 years. The prevalence of a high risk of psychological distress was 5.2% (103/2000), while the prevalence of moderate risk of psychological distress was 15.2% (303/2000). Multivariate logistic regression analysis showed that being male, having poor self-rated health, having poor subjective financial status, binge drinking in the past year, and lifetime use of any illicit drug were associated with a higher likelihood of having a high risk of psychological distress. One in six adults in Serbia has a high risk of psychological distress, while one in twenty has a moderate risk. The findings of this study urge targeted actions to protect and improve the health of people in psychological distress and drug and alcohol users. © 2023 by the authors.
