Community Knowledge About Climate Change and Industrialization Impacts on Recurrence of Dengue Epidemics in Selected Districts in Tanzania: A Cross-Sectional Study.
Article in Health science reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background and Aims: Dengue fever epidemics pose an increasing public health threat in Tanzania. Climate change and industrialization may influence outbreaks, while community knowledge plays a vital role in prevention. This study examined public knowledge about environmental and anthropogenic impacts on dengue transmission. Methods: A cross-sectional study was conducted from April to June 2022 with 482 participants from Bahi, Kyela, and Ngorongoro districts. A validated questionnaire assessed demographic characteristics and knowledge about dengue epidemiology related to climate and industrialization. Multinomial logistic regression and Results: Over half of the participants (52.9%) were male, and most were aged 26-35 (33.2%). Only 21% demonstrated a good understanding of industrialization's health impacts, while 19% knew the climate change linkage with dengue. Significant knowledge gaps exist regarding climate change and industrialization impacts linked to recurrent epidemics (44.2% poor knowledge). Age over 35 (AOR 1.73, 95% CI 1.39-2.14), primary education or less (AOR 0.77, 95% CI 0.59-0.99), and unemployment (AOR 0.31, 95% CI 0.23-0.42) were associated with poor knowledge. Gender and occupation significantly predicted climate change knowledge ( Conclusion: Communities in dengue-endemic areas have limited knowledge about climate and anthropogenic drivers of recurring epidemics. Targeted educational interventions can improve understanding and preventative behavior among high-risk demographics.
