COVID-19 effects on diet, sleep, and physical activity among mid- to late-adolescents residing in the deep south in the United States.

PURPOSE

This study investigated the differential impact of COVID-19 on United States (US) adolescents' physical health as a function of sociodemographic factors over 18 months. It was hypothesized that the impact of COVID-19 and its mitigation efforts on physical health factors would vary by sociodemographic factors.

DESIGN AND METHODS

Data were drawn from a longitudinal study in which participants (ages 16 or 18) self-reported sleep, diet, and physical activity over 18months. Participants were enrolled between 2018 and 2022. Participants (n = 190, 73% Black/African American, 53% female) provided 1330 reports over 194 weeks (93 weeks before and 101 weeks after COVID-19 restrictions implementation).

RESULTS

Physical health outcomes moderated by demographic factors were measured and assessed over 18 months. Multilevel models and general estimated equations estimated the impact of COVID-19 restrictions on participants' health outcomes. Sleep and physical activity worsened after COVID-19 regardless of moderating factors, but some specific outcomes varied across subgroups.

CONCLUSIONS

This study diversifies the literature on the impact of COVID-19 and its mitigation measures on adolescents' social health. Further, it is based in the US's Deep South, largely populated by those identifying as Black/African American or of low socioeconomic status. Both subgroups are underrepresented in US-based health outcomes research. COVID-19 directly and indirectly impacted adolescents' physical health.

PRACTICE IMPLICATIONS

Understanding if and how COVID-19 impacted adolescents' health will inform nursing practice to adapt to and overcome adverse sequelae to promote positive patient health outcomes.
