A randomized controlled trial to evaluate the impact of a geo-specific poster compared to a general poster for effecting change in perceived threat and intention to avoid drowning 'hotspots' among children of migrant workers: evidence from Ningbo, China

Gaps in the evidence for interventions in global drowning research

BACKGROUND

Since 2014, drowning has received increased political attention. Translating this political commitment to saving lives needs policy-supported evidence-informed interventions. An evidence gap map (EGM) was developed, which aims to facilitate the strategic prioritisation of future research and efficient commissioning of interventions.

METHODS

Available evidence was sought by searching four electronic databases using drowning key terms from 2005 to 2023. Peer-reviewed studies, which measured the outcome of a drowning prevention intervention, were included in the EGM. Classification of interventions was guided by the WHO's recommendations for drowning prevention interventions and strategies. Intervention outcomes were classified into health, social, economic, policy and other supporting outcomes.

RESULTS

49 intervention studies were identified. Of these, 25 studies were conducted in high-income countries (HICs), 19 in low- and middle-income countries (LMICs), 3 in both HICs and LMICs and 2 were not country specific. Interventions, which used community education, were the most common (n=29, 27%), followed by teaching school-age children swimming and water safety skills (n=13, 12%) and others combined (n=66, 61%). Majority of interventions focused on process outcomes such as knowledge acquisition (n=42, 39%) in comparison with objective outcomes such as incidence of drowning mortality (n=21, 19%). No studies reported on interventions that manage flood risks.

CONCLUSIONS

Knowledge gaps of effective drowning prevention interventions were identified using an EGM, emphasising the need for methodological advancements reporting on outcomes measures, implementation research and targeted research among high-risk populations in LMICs.

Prevention of childhood unintentional injuries in low- and middle-income countries: A systematic review

Injuries are a leading cause of death and disability among children. Numerous injury prevention strategies have been successful in high-income countries, but the majority of unintentional injuries happen to children living in low- and middle-income countries (LMICs). This project aims to delineate the childhood injury prevention initiatives in LMICs. For inclusion, peer-reviewed articles needed to address unintentional injury, include children <18, assess a prevention-related intervention, contain a control group, and be published after 1988. Two pairs of reviewers evaluated articles independently to determine study eligibility. 74 articles were included. 30 studies addressed road traffic injuries, 11 drowning, 8 burns, 3 falls, 8 poisonings, and 21 an unspecified injury type. The findings show positive effects on injury outcome measures following educational interventions, the need for longer follow-up periods after the intervention, the need for effectiveness trials for behavior change, and the need for an increase in injury prevention services in LMICs. This is the first systematic review to summarize the prevention initiatives for all types of childhood unintentional injuries in LMICs. Increased attention and funding are required to go beyond educational initiatives with self-reported measures and little follow-up time to robust interventions that will reduce the global burden of unintentional injuries among children.

The Effectiveness of Traditional Media (Leaflet and Poster) to Promote Health in a Community Setting in the Digital Era: A Systematic Review

Introduction: The use of health promotion media in the digital era, such as e-health and m-health, is increasing. However, traditional health promotion media, such as posters and leaflets, are still used. This review aimed to identify the effectiveness of the use of traditional health promotion media (leaflets and posters) in a community setting in the digital era.Methods: The data was gathered using the following steps: (1) determining the topic, (2) determining the keyword chain, (3) looking for the relevant literature in the database and (4) analyzing the article. The search using a predetermined keyword chain in Scopus, Science Direct and Sage Journals produced 208 publications.Results: After applying the inclusion and exclusion criteria, 16 publications were selected for review.Conclusion: Traditional health promotion media such as leaflets and posters are still useful in the current digital era, especially for adult respondents. This form of media will be more effective when combined with other media such as videos, telephone interactions, games and others.
