    Background Prolonged sitting time in the workplace constitutes a significant portion of waking hours. Sedentary behaviour is associated with higher risks of cardiovascular diseases, obesity, and all-cause mortality. Interventions to reduce workplace sitting, such as health apps, height-adjustable desks, and active breaks, have shown relative effectiveness in improving health outcomes. Among these, computer prompt interventions represent a simple and scalable strategy that can remind workers to take breaks and reduce sedentary behaviour. This study evaluates the effectiveness of computer prompt interventions to reduce sitting at work compared to no intervention or combined strategies. Methods Primary studies were searched in PubMed (MEDLINE), EMBASE, Scopus, and CENTRAL of the Cochrane Library. The search was conducted until December 2024. Keywords included terms like “sedentary behaviour,” “computer prompts,” “sitting time,” and “office workers.” Only randomized controlled trials (individual or cluster) involving desk-based workers aged 18 or older that evaluated computer prompt software were included. Risk of bias was assessed using the Cochrane Risk-of-Bias tool (RoB2). Mean differences with 95% confidence intervals (CI) were calculated for sitting time and secondary outcomes. Analyses were performed using RevMan and R software, and GRADE methodology was applied to assess the certainty of evidence. Results From 17,880 records, 18 studies involving 1164 office workers were included in the analysis. Ten studies focused exclusively on computer prompts, while 8 studies implemented combined strategies (e.g., computer prompts plus sit-to-stand desks). The median intervention length was 8 weeks, ranging from one to 24 weeks. Studies using only computer prompts included breaks lasting from 1 to 10 min every 30 min up to an hour. Combined strategies included breaks from 6 to 30 min every 30 min up to 3 h. According to objective measurements, the meta-analysis showed a significant reduction of 12.46 min/workday in sitting time (95% CI: -18.12, -6.80) and a significant increase of 1029.99 steps/workday (95% CI: 815.97, 1244). Secondary outcomes included work-related, musculoskeletal, and cardiometabolic outcomes favouring computer prompts but not statistically significant. The certainty of evidence for primary outcomes is rated low to moderate according to GRADE. Conclusions Computer prompt software interventions show effectiveness in reducing sitting time among office workers. However, more long-term prospective studies with larger sample sizes are needed to accurately determine the effectiveness of computer prompts on various work- and health-related outcomes.

    This study analyses the feasibility and effectiveness of BabyMICARE, a manualised intervention programme aimed at improving the interactions between caregivers and infants and toddlers with Down syndrome. The programme’s goal is to enhance caregivers’ sensitivity and reduce directivity during early interactions, particularly during play and daily routines. A pre-test and post-test design was used with 40 dyads of infants with Down syndrome and their caregivers, who were divided into a control group (n = 20) and an intervention group (n = 20), based on baseline scores in key interaction subscales. Sessions were conducted over 10 weeks by trained psychologists. Parent-infant interaction was assessed using the MACI coding system, which measures aspects such as sensitive responsiveness, directivity and the level of reciprocity between the parent and the child. The programme showed high feasibility, with a 100% attendance rate but some rescheduling. Caregivers evaluated it positively. The intervention group demonstrated significant improvements in five of eight MACI scales, particularly in sensitive responsiveness and nondirectiveness, while no changes were observed in the control group. The results suggest that BabyMICARE is a feasible and effective intervention for promoting more responsive, less directive interactions, which may be crucial in fostering children’s development.

    <jats:p>In Chile, during the COVID-19 pandemic, reports of cyberbullying victimization increased for adolescents and younger adults. Research has shown that cyber-victims—adolescents and young adults alike—are at greater risk for mental health problems such as depression as a result of this negative type of aggression. Yet, a paucity of research has examined the individual mechanisms germane to cyber-victim depression. We focused on loneliness for the current study. We hypothesized that cyber-victimization would be positively related to depressive symptoms through increased fears of loneliness and that this effect would differ between adolescents and younger adults. Thus, we examined a sample of 2370 participants from all main regions of Chile aged from 15 to 29 years. Moderated mediation results showed a negative effect of cyberbullying on depression, which was mediated by increased fears of being alone. The effect of frequency of cyberbullying on fear of loneliness was stronger for younger adults compared to adolescents. Our results suggest different mechanisms for both age groups, which can inform prevention programs and their specific activities.</jats:p>

    <jats:p>Context. Meditation incorporation helps to fight against disorders such as depression, stress, and anxiety. Specifically, few studies have studied Osho’s Active Meditation on young people, but observed evidence using passive meditation shows that it could improve stress well-management, emotional control, and other mental unhealthy conditions. Goal. The present study pointed to evaluate the results of an occupational therapy program centered on active meditation on hair cortisol concentration in a sample of undergraduate healthcare students. Methods. Undergraduate students from the University of Chile’s health careers were divided at random into control (<jats:inline-formula> <math xmlns="http://www.w3.org/1998/Math/MathML" id="M1"> <mi>n</mi> <mo>=</mo> <mn>7</mn> </math> </jats:inline-formula>) and treated groups (<jats:inline-formula> <math xmlns="http://www.w3.org/1998/Math/MathML" id="M2"> <mi>n</mi> <mo>=</mo> <mn>15</mn> </math> </jats:inline-formula>). The treated group participated in an active meditation program once a week for three months. This treatment included different techniques such as Chakra Sounds, Nataraj, Mandala, Kundalini, Devavani, Gourishankar, and Nadabrahma. Hair samples were taken before and after the treatment period to measure cortisol. Results. The control group increased cortisol level <jats:inline-formula> <math xmlns="http://www.w3.org/1998/Math/MathML" id="M3"> <mn>168.9</mn> <mo>±</mo> <mn>76.8</mn> </math> </jats:inline-formula> pg/mg compared with initial levels. The treated group shows a decrease of initial cortisol values in <jats:inline-formula> <math xmlns="http://www.w3.org/1998/Math/MathML" id="M4"> <mn>28.5</mn> <mo>±</mo> <mn>12.8</mn> </math> </jats:inline-formula> pg/mg after meditation protocol application. Conclusions. Blending active meditation in students’ daily routine through occupational therapy intervention might prevent undergraduate students’ stress in healthcare careers.</jats:p>
