Association between ultra-processed food consumption, carbon footprint awareness and sustainable and healthy eating behaviors in adult: a cross-sectional study.

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
backgroundUltra-processed food (UPF) consumption is rising globally, posing significant health and environmental risks. While studies have extensively examined ultra-processed food (UPF) consumption, they often overlook the factors influencing awareness and behavioral shifts toward sustainable and healthy eating. This study aims to examine the relationship between UPF consumption, carbon footprint awareness, and sustainable and healthy eating behaviors in adults.
methodsThis cross-sectional study was conducted with 1748 adults aged 18-65 years. Participants' Eating Behaviors and awareness levels were assessed using three validated scales: the Sustainable and Healthy Eating Behaviors Scale (SHEBS), the Highly Processed Food Consumption Screening Questionnaire (sQ-HPF), and the Carbon Footprint Awareness Scale (CFAS). Pearson correlation and Linear regression analyses were used to assess associations.
resultsThe mean age of participants was 29.4 ± 12.16 years and 55.7% had high UPF consumption. Participants' general characteristics were assessed through a questionnaire.Pearson correlation analyses revealed that UPF consumption (sQ-HPF score) was negatively correlated with carbon footprint awareness (CFAS) (r = -0.184, p < 0.001) and sustainable and healthy eating behaviors (SHEBS) (r =-0.296, p < 0.001). A strong positive correlation was observed between CFAS and SHEBS scores (r = 0.653, p < 0.001), including all SHEBS sub-dimensions (r = 0.325-0.911, p < 0.001). Linear regression analysis indicated that age (β = -0.293), CFAS (β = -0.264), and SHEBS (β=-0.230) significantly predicted UPF consumption (R²=0.373, p < 0.001). Furthermore, CFAS was predicted by SHEBS (β = 0.658) and UPF consumption (β = -0.141) (R² = 0.672), while SHEBS was predicted by CFAS (β = 0.644) and UPF consumption (β = -0.142) (R² = 0.680, p < 0.001).
conclusionsUPF consumption is inversely associated with both carbon footprint awareness and sustainable, healthy eating behaviors. Strengthening environmental awareness and promoting sustainable eating practices may be effective strategies for reducing UPF intake in adults. These findings underscore the importance of integrative public health efforts targeting both nutritional and environmental dimensions.
