BACKGROUND/OBJECTIVES: This study aimed to investigate the lifestyle and the behavioral factors that influence the nutritional status of adolescents from Transylvania, Romania.

METHODS

The Global School-Based Student Health Survey (GSHS) was used to collect data from 900 adolescents between 11 and 18 years old from the Transylvania region, Romania. This study assessed nutritional status by calculating BMI indicators adjusted to Z-Score, cut-off points according to the World Health Organization (WHO), using self-reported weight and height; perceived health status; food vulnerability; physical activity; addictive behaviors (cigarette, alcohol and drug consumption); number of hours spent in front of the computer/phone; hand and oral hygiene; sitting time/day; and sleep. Multivariate logistic regression was used to establish the lifestyle factors that influenced nutritional status.

RESULTS

The results showed that 8.7% ( = 78) of girls and 15.2% ( = 137) boys were overweight and obese. In total, 75% of the respondents were engaged in sedentary behaviors, and 65.8% ( = 592) had more than 2 h/day of screen exposure, considering that 98.7% of the study population had a mobile phone. The Romanian adolescents had poor dietary behaviors: over 80% of them did not meet the recommended amount of vegetable and fruit intake per day. Increased BMI was associated with higher-strength physical exercise and with being a boy.

CONCLUSIONS

While some positive trends are evident, such as good oral and hand hygiene and low prevalence of smoking and drug use, significant challenges remain in areas like nutrition, physical activity, alcohol consumption and screen time.
