This study focuses on the national and subnational estimation of prevalence, incidence, disability-adjusted life years (DALYs) related to self-harm and suicide mortality in Iran. These indicators of disease burden were analyzed over the period from 1990 to 2021, with stratifications based on sex, age and geographic location. Additionally, the percentage change observed between 1990 and 2021 was documented. The age-standardized prevalence rate (per 100,000) of self-harm decreased from 173.92 (95% UI: 146.13–208.75) in 1990 to 131.2 (95% UI: 110.55–156.67) in 2021, reflecting a percentage change of −0.25% over the period. In terms of self-harm prevalence in 2021, males had a higher rate (137.62 per 100,000) compared to females (124.82 per 100,000). The findings of the current study revealed that, despite significant challenges such as demographic shifts, economic instability and the impacts of war, the trends in self-harm incidents and suicide mortality rates in Iran have generally been on the decline. Additionally, it was observed that suicide-related deaths were more prevalent among males when compared to females. However, when examining self-harm behaviors over previous decades, these acts appeared to be more frequent among females.

This study examined the acoustic realization of focus in Cantonese-English bilingual autistic children’s first language (L1) Cantonese, compared to bilingual typically developing (TD) children and adults, and explored the effects of bilingualism on the production. Results from an elicitation task showed that bilingual autistic children primarily relied on duration to mark focus in L1 Cantonese, similar to adults, but exhibited weaker use of pitch and intensity compared to bilingual TD children. Second language (L2) English exposure and proficiency did not influence focus marking in bilingual autistic children likely due to their later and reduced English exposure compared to TD children. Conversely, bilingual TD children’s prosodic use was modulated by English exposure and proficiency. These findings reveal that bilingualism does not hinder autistic children’s prosodic focus production in their L1 Cantonese and highlight distinct bilingualism effects on prosodic focus production in autistic and TD children.

Word frequency databases like SPALEX and SUBTLEX-ESP treat Spanish as a uniform language, but prior studies and an initial survey (Experiment 1) revealed significant lexical differences between Spanish in Spain and Latin American countries, especially Chile. To establish subjective frequencies of Spanish word usage, an extended survey (Experiment 2) was conducted with Chilean participants, categorizing words by usage area: General, Spain, Chile, and Latin America. Consistent with the initial survey, Chilean participants assigned subjective higher ratings to General and Chilean words. In a lexical decision experiment (Experiment 3), participants responded faster and more accurately to words from these categories. Using survey data, simulations with Multilink+ (Experiment 4) revealed that subjective word ratings better predicted Chilean reaction times than frequencies from existing databases. These findings emphasize the need to address Spanish dialectal differences in research, with word ratings offering a more accurate measure of region-specific lexical nuances than current databases.

During the perinatal period, women in low- and middle-income countries experience high rates of common mental disorders (CMDs). We aimed to estimate CMD prevalence at 6 and 12 months postpartum in Rahim Yar Khan (RYK), Pakistan, and identify factors associated with postpartum mental health. We conducted secondary analysis of a longitudinal birth cohort study, which was nested within the control arm of a community-based, cluster-randomized trial that enrolled pregnant women in their third trimester (n = 2,122). Mental health was assessed using the Self-Reporting Questionnaire. Factors associated with postpartum mental health were explored using mixed-effects linear regression, and associations between preconception, antenatal and postpartum CMDs were assessed using robust Poisson regression. The prevalence of CMDs was 16% and 17% at 6 and 12 months postpartum, respectively. Women who reported that their husbands were unhappy had poorer postpartum mental health, whereas high social support was associated with improved postpartum mental health. History of antenatal CMDs was associated with increased risk of CMDs at 6 and 12 months postpartum (adjusted risk ratio = 2.60 and 1.90, 95% confidence interval: 1.69–4.01 and 1.40–2.58, respectively). Mothers with identified risk factors may benefit from targeted mental health support during the perinatal period.

It has been argued that lexical access in bilinguals is language nonselective. However, little is known about how the input modality (spoken or written) affects cross-language activation during listening and reading. The current study characterizes the nature of within- and cross-language competition for spoken and written words in adults who are bilingual and biliterate in Spanish and English. Using a recently developed cross-modality version of the Visual World Paradigm, we found that competition differs for spoken and written words. For spoken words, the auditory stimulus unfolds overtime giving an additional boost to within- and cross-language competition. Conversely, written words can be seen at once, and thus, incremental processing is less of a factor, resulting in less competition within a language and no competition across languages. The findings show that word recognition is fundamentally language nonselective but can behave in selective ways depending on the modality of the input and language experience.

Continuous traumatic stress (CTS) exposure describes extended and ongoing collective trauma exposure that is associated with potential future danger and threat to the community. CTS has generated debate in the context of current definitions of trauma and posttraumatic stress disorder (PTSD) in the DSM-5. Prevalence data on posttraumatic stress symptoms (PTSS) and PTSD in adolescents aged 10 to 24 years following CTS exposure in Sub-Saharan Africa are lacking. This systematic review and meta-analysis sought to address this gap. We also synthesized evidence on other trauma-related mental disorders and moderators such as mean age, sex, country income, education level, PTSS/PTSD assessment tool, and recruitment method. A systematic literature search covering four databases yielded 460 papers that were screened for eligibility, with 10 studies included. Data were extracted and coded, and a meta-analysis of the pooled prevalence of clinically significant PTSS/PTSD was conducted. Results indicated a pooled prevalence of PTSS/PTSD of 32.0% (95% CI: 20.7% to 46.0%). Country income (World Bank category) and type of assessment (clinician-administered vs. self-report) significantly moderated the prevalence of PTSS/PTSD. Further research is needed to not only measure CTS as an exposure but also as a response separate from PTSS/PTSD among adolescents in Sub-Saharan Africa. Additionally, research is needed to determine the validity, reliability, and cultural relevance of CTS response measures. Such studies will help in better understanding the psychosocial impact of CTS exposure on adolescents and inform the development of future interventions. Detailed data on the prevalence of PTSS/PTSD and moderators thereof following CTS exposure in Sub-Saharan Africa are sparse. Further studies are needed to characterize CTS-related comorbidities and related phenomena in adolescents living under conditions of CTS exposure and to optimize evidence-based interventions.
