Violence is a major public health concern, but long-term hospital-based analyses in Latin America remain scarce. This study examined trends, structural breaks, and seasonality of violence-related emergency visits at the José Casimiro Ulloa Emergency Hospital in Lima, Peru, between 2015 and 2024. A retrospective analysis of 14,570 visits was performed, classifying cases according to the World Health Organization typology into self-inflicted, interpersonal community, and interpersonal family violence. Descriptive statistics were stratified by sex, life stage, migratory status, and pandemic period: pre-pandemic (2015–2019), pandemic (2020–2021), and post-pandemic (2022–2024). Time-series analyses included segmented regression and seasonal-trend decomposition. Males (78.3%), youth, and adults were the most affected groups. Interpersonal community violence accounted for 94.2% of cases and closely mirrored the overall series, peaking at 327 visits in July 2019 and falling to 28 in April 2020. Segmented regression showed significant immediate decreases at the onset of the pandemic (−71.6 visits, p < 0.001) and partial rebounds after 2022. Family violence remained consistently low and stable, while self-inflicted violence displayed a pre-pandemic upward trend, a sharp decline in 2020, and higher post-pandemic levels. Seasonality was evident before 2020, disappeared during the pandemic, and re-emerged with reduced amplitude thereafter. The COVID-19 pandemic caused abrupt but heterogeneous disruptions in violence-related emergency visits in Lima.

Time series of violence-related emergency visits at José Casimiro Ulloa Emergency Hospital, 2015–2024: (A) total visits, (B) by sex, (C) by life stage, and (D) by reason for care. Light gray and white bands denote quarterly intervals; the dark gray band highlights the COVID-19 pandemic period (2020–2021).

Background: Ageing leads to physical, cognitive, and social changes that affect people’s functioning and social participation. Health literacy, sociodemographic, and environmental factors influence health outcomes and access to care. This study aimed to characterize the health and functioning of Portuguese adults aged 65 and over, focusing on sociodemographic factors, health status, lifestyle, fall risk, functional capacity, and social participation, and on comparing rural and urban populations. Materials and Methods: An exploratory, cross-sectional study was conducted using data from older adults who completed the FallSensing screening protocol. Participants were classified by residence type (rural vs. urban), and group comparisons were made. Results: The sample (n = 474) was predominantly female (66.5%) with a mean age of 74.62 (±6.49) years. Rural participants were older (76.87 ± 6.89 vs. 73.50 ± 5.87) and had higher body mass index (BMI) (28.32 ± 4.31 vs. 27.51 ± 4.12), lower educational attainment—for example, 22.9% had no formal education compared to 7.0% of urban participants—and a higher prevalence of hypertension (72.6% vs. 55.4%), whereas urban participants experienced higher rates of osteoporosis (24.4% vs. 14.3%), hearing loss (41.9% vs. 26.9%), and alcohol consumption (12.7% vs. 2.3%) (p ≤ 0.05). Rural residents also demonstrated significantly poorer results for grip strength (21.03 ± 7.36 vs. 23.73 ± 8.61), gait speed (1.17 ± 0.44 vs. 1.45 ± 0.39), and the Timed Up and Go (TUG) test (13.4 ± 10.40 vs. 9.62 ± 4.43), as well as lower exercise self-efficacy (12.83 ± 4.97 vs. 14.28 ± 4.40) (p < 0.001), and more pronounced moderate-to-severe restrictions in social participation (28.0% vs. 15.7%) (p = 0.013). They reported greater use of assistive devices and more severe limitations in social participation. Although falls were reported more often in urban areas, rural residents experienced greater fall frequency. Conclusions: These findings suggest that rural living is associated with lower functional capacity and poorer health, underscoring the need for targeted physiotherapy and primary care strategies in rural settings.

This paper reports on data from two trials about stakeholders’ attitudes to school-based mental health screening. Study 1 reports data from 6228 students from grades 4 to 12 while Study 2 reports data from 267 caregivers and 34 educators from a larger trial. All three groups of stakeholders reported broadly positive attitudes toward school-based screening. Few students reported distress from questions and most agreed that schools should screen. Caregivers and educators reported positive attitudes toward the use and implementation of screening and reported few concerns about harms. Educators who conducted screening reported mostly positive experiences, although they noted high resource burden and false positives and negatives.
