Background and AimHealth promotions among the adolescent population have a significant role in achieving the 2030 sustainable development goals of the World Health Organization. The COVID-19 pandemic has led to several devastating impacts on the health, economic, social, and healthcare systems, and adolescents’ health promotions are no exception. We assessed health promotion behaviors and associated factors among the adolescent population of northern Saudi Arabia (KSA).MethodsWe used the Arabic version of the adolescent health promotion scale (AHPS-40) among the 400-adolescent population. The AHPS-40 assessed six domains of adolescent health behavior: nutrition, social support, health responsibility, life appreciation, exercise, and stress management. We applied the Chi-square test to identify the associated factors of adolescent health promotion activities and the logistic regression test to find the predictors for overall health promotion categories.ResultsOf the studied participants, the mean ± SD of the total AHPS-40 was 103.31 ± 18.78. The nutrition domain of the AHPS-40 was significantly associated with the age group (p= 0.002), and the social support domain was significantly related to fathers’ (p= 0.022) and mothers’ education (p= 0.006). The exercise domain of AHPS-40 was significantly associated with age group (p= 0.018) and school level (p= 0.026). Gender was significantly associated with most of the six domains. Furthermore, more than half (52.7%) of them had a low health promotion behavior, which was significantly associated with gender (adjusted odds ratio = 1.59, 95% CI of AOR = 1.04 –2.45,p= 0.032).ConclusionOur study results suggest improving health promotion behaviors by instituting awareness-raising and health promotion intervention programs for adolescent groups. Furthermore, we recommend a focused, exploratory, mixed-method survey among the adolescents of other regions of KSA to identify the region-specific adolescent’s health promotion behaviors.
