Background: Internet and social media addiction have become a health problem due to their negative impact on health and well-being. Internet use time is also frequently examined as an outcome, offering complementary insight into usage patterns. Health education is a key tool during adolescence to promote healthy behaviours, supporting self-regulation and fostering healthier patterns of Internet and social media use. The aim of this study is to evaluate the effectiveness of health education interventions for reducing Internet addiction, Internet use time, and social media addiction among adolescents. Methods: We conducted a systematic review with meta-analysis following PRISMA guidelines. Eligible studies were experimental or quasi-experimental designs involving adolescents and evaluating health education interventions, with outcomes on Internet addiction, Internet use time, or social media addiction. A search was conducted in Medline, WoS, Scopus, CINAHL, PsycINFO and PubMed Central. Study selection, data extraction, and synthesis were performed independently by pairs of researchers. To evaluate risk of bias, the Cochrane Collaboration’s tool was used for randomised studies, and ROBINS-I for non-randomised studies. Certainty of evidence was assessed with GRADE. Results: Sixteen studies with 13,562 participants were included in the systematic review. Six were included in the meta-analysis for Internet addiction. Most interventions were conducted in educational settings, with participants showing variability in their Internet use patterns across studies. Across studies, observed characteristics included group delivery and participatory approaches, parental involvement, promotion of healthier Internet use, and inclusion of broader educational content addressing health-promotion topics. The review found generally favourable effects on Internet addiction and Internet use time. Evidence on social media addiction was limited. The meta-analysis for Internet addiction showed a statistically significant difference in favour of the intervention, with a large effect size (SMD = − 1.88; 95% CI [− 2.64, − 1.11], p < 0.00001). Subgroup analysis showed a large and significant effect in adolescent only interventions (SMD = − 1.93; 95% CI [− 2.84, − 1.02], p < 0.0001) and in parent involved interventions (SMD = − 1.81; 95% CI [− 2.95, − 0.68], p = 0.002). Conclusions: Health education shows promise for reducing Internet addiction and Internet use time among adolescents. Evidence on social media addiction remains limited. Trial registration: The study protocol was registered in PROSPERO (CRD42024568029).

Introduction: Population aging has opened up a new and broad field of study for health science in which nursing must investigate to guarantee the health autonomy of older people. Objective: To make visible the Gerontological Day Centers (CDG) and the activities of nursing professionals in these centers in Huelva. Methodology: A qualitative investigation has been carried out using questionnaires and interviews directed at the management and nursing staff of several Day Centers in Huelva and the province. Results: The CDG are an intermediate resource with multiple objectives and functions, which offer quality of life for both the elderly and their families. They are made up of a basic team of professionals who work on a non-permanent basis. The role of nursing is essential, but it has a very poor employment situation. Conclusion: These centers provide professional care and allow them to remain in their usual homes, favoring the quality of life and autonomy of this older population. The bibliography on this topic is scarce, so it is considered necessary to deepen its research along with the implementation of programs and improvement proposals that make these socio-health centers known. Introducción: El envejecimiento poblacional ha desplegado un nuevo y amplio campo de estudio para la ciencia sanitaria en el que la enfermería debe investigar para garantizar la autonomía en salud de las personas mayores. Objetivo: Visibilizar los Centros de Día Gerontológicos (CDG) y las actividades de los profesionales de enfermería en dichos centros en Huelva. Metodología: Se ha realizado una investigación cualitativa a partir de cuestionarios y entrevistas dirigidas al personal de dirección y enfermería de varios Centros de Día de Huelva y provincia. Resultados: Los CDG son un recurso intermedio con múltiples objetivos y funciones, que ofrecen calidad de vida tanto para los mayores como para sus familiares. Se componen de un equipo básico de profesionales que trabaja de forma no permanente. La figura de la enfermería es esencial, pero cuenta con una situación laboral muy deficiente. Conclusión: Estos centros proporcionan cuidados profesionales y permiten la permanencia en los domicilios habituales favoreciendo la calidad de vida y autonomía de esta población mayor. La bibliografía sobre este tema es escasa, por lo que se considera necesario profundizar en su investigación junto con la puesta en marcha de programas y propuestas de mejora que den a conocer estos centros sociosanitarios.

A bibliografia sobre este tema é escassa, pelo que considera-se necessário aprofundar a sua investigação juntamente com a implementação de programas e propostas de melhoria que dêem a conhecer estes centros sócio-sanitários.

Background/Objectives: Population ageing has increased the importance of promoting wellbeing and healthy ageing. Gerontological day centres may support the wellbeing of older adults. This study aimed to examine quality of life, active ageing, perceived social support, and loneliness in older adults attending gerontological day centres and to identify the factors associated with quality of life. Methods: A cross-sectional descriptive study was conducted with 109 participants aged 60–98 years recruited from gerontological day centres in Huelva and Seville, Spain. Data were collected using the WHOQOL-BREF, the Multidimensional Scale of Perceived Social Support (MSPSS), the ESTE II Loneliness Scale, and the Active Ageing Scale. Descriptive and comparative analyses were performed, followed by multiple linear regression to identify factors associated with quality of life. Results: Mean scores were 14.46 (SD = 1.83) for quality of life, 3.06 (SD = 0.36) for active ageing, 10.14 (SD = 3.00) for social loneliness, and 5.62 (SD = 0.93) for perceived social support. The multiple linear regression model accounted for 30.8% of the variance in quality of life (adjusted R² = 0.288), leaving approximately 69.2% of the variance unexplained by these factors. In this model, active ageing (β = 0.395; p < 0.001), social loneliness (β = −0.246; p = 0.004), and perceived social support (β = 0.188; p = 0.027) were independent predictors of quality of life. Bivariate analyses should be interpreted with caution as they were strictly exploratory. Conclusions: The study demonstrates that active ageing, low social loneliness, and solid perceived social support are the core multivariable predictors of quality of life among older adults in day centres. Secondary exploratory trends suggested minor baseline links with sleep duration, marital status, and employment status. Interventions should prioritize promoting active ageing and strengthening social networks, while future research needs to explore additional covariates to account for the remaining unexplained variance in well-being.
