Association between physical activity and sociodemographic and behavioural factors among physical education students at a Brazilian public university.

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
backgroundThis study aimed to analyze the prevalence of physical activity and its association with sociodemographic factors and lifestyle indicators among physical education students at a Brazilian public university.
methodsThis was a cross-sectional observational study with a quantitative approach. A total of 190 students enrolled in on-site undergraduate programs (teacher training and bachelor's degree) participated, with a mean age of 21.2 ± 4.5 years; 52.1% were men and 47.9% were women. Data were collected in person using an electronic form (Google Forms) comprising sociodemographic variables, physical activity level (IPAQ-short version), and the Fantastic Lifestyle questionnaire. The primary outcome was physical activity level, classified as active (≥150 min/week of moderate-to-vigorous physical activity [MVPA]) or inactive (<150 min/week of MVPA). Sociodemographic characteristics and lifestyle-related variables, including overall lifestyle, diet, smoking, alcohol consumption, leisure, sleep, and health perception, were examined as independent variables associated with physical activity level. Analyses were performed using SPSS version 21.0, employing descriptive statistics, chi-square/Fisher's exact tests, and binary logistic regression (Odds Ratio - OR; 95%CI; p ≤ 0.05).
resultsAmong participants, 94.2% were classified as physically active; 82.6% presented an adequate lifestyle; and 37.9% were classified as overweight or obese according to BMI. No significant associations were observed between physical activity level and sociodemographic or behavioural variables, except for health perception, which was significantly associated with physical inactivity. Negative health perception was the only factor associated with physical inactivity (OR = 14.30; 95%CI: 2.48-82.22; p = 0.003), suggesting that subjective health perception may be more strongly associated with physical inactivity than sociodemographic or behavioural characteristics among future health-promotion professionals.
conclusionsIn summary, physical education students demonstrated a high prevalence of physical activity and a predominantly adequate lifestyle. Negative health perception was the only factor associated with physical inactivity. Future investigations are encouraged to include additional variables to provide a broader analytical perspective.
