Impact of environmental and lifestyle factors on adolescent sleep health in urban and semiurban areas.

OBJECTIVES

This study examines the impact of lifestyle factors on adolescent sleep health across urban and semiurban settings.

METHODS

A cross-sectional survey was conducted among 1459 adolescents aged 14-19years from Tabriz (urban) and Hadishahr (semiurban), two cities with contrasting environmental conditions. Sleep duration and sleep deprivation were assessed using self-reported data, alongside key sociodemographic, behavioral, and health-related factors.

RESULTS

The results showed that adolescents in urban area were significantly more likely to experience shorter sleep durations (OR=0.63, 95% CI [0.48, 0.83]) and sleep deprivation (OR=0.66, 95% CI [0.51, 0.85]) compared to those in semiurban environments. Age was positively associated with short sleep (OR=1.21, 95% CI [1.07, 1.38]), while smoking (OR=1.46, 95% CI [1.02, 2.08]) and chronic cough (OR=1.35, 95% CI [1.01, 1.80]) were also linked to reduced sleep duration. In contrast, semiurban residents slept an average of 20minutes longer than urban residents (β=0.34, 95% CI [0.17, 0.51]). Sleep deprivation was strongly associated with lower Parent's income (OR=0.78, 95% CI [0.61, 0.98]) and daytime fatigue (OR=1.58, 95% CI [1.26, 2.00]).

CONCLUSIONS

The study highlights the need for public health interventions that address environmental barriers to healthy sleep, particularly in urban settings, to mitigate the long-term health risks associated with sleep deprivation.
