Objective: To evaluate gender differences in physical activity (PA), stress and resiliency during the COVID-19 pandemic. Participants: Students (n = 300) at a southeastern US university. Methods: Perceived Stress (PSS), Resiliency (BRS), Life Events (LEI), and PA were recorded via online survey in Summer 2020. PSS, BRS, LEI, and PA were compared between males and females. Two-way ANOVAs examined gender and frequency effects on PSS and BRS. Results: Females had lower BRS and higher PSS and LEI scores than males (all p < .001). PSS/BRS scores were more strongly correlated with PA in males. Significant gender × frequency interactions were found for PSS (vigorous, p = .03) and for BRS (moderate, p = .049). There was a significant main effect of frequency for PSS with strength training (p < .001). Conclusions: Results suggest that interventions may be particularly needed for females and those with low PA levels.

Concerns regarding the continued high prevalence of childhood overweight and obesity have created a need for proactive approaches to behavior change. The Family Nutrition and Physical Activity (FNPA) screening tool was developed for research and clinical use to identify home environments and behaviors that could predispose youth to increased weight. FNPA scores have been shown to correlate with body mass index (BMI) percentiles in first-grade students and to predict unique variance in change in BMI percentiles from first to second grade. The FNPA has been used for family behavior counseling and is now a standard component of well-child visits throughout the Geisinger Health System in Pennsylvania. Parents complete the FNPA prior to annual visits, and providers can discuss areas of concern based on screening results. Children of parents who complete the FNPA have shown smaller increases in BMI z-scores over the following year than children of parents who did not complete the FNPA. The FNPA is also used to inform the arrangement of family-centered obesity treatment for children. Recently, the FNPA has undergone a systematic update to ensure its continued relevance and utility. The updated tool is provided, and current and future users can access more information about the tool at myfnpa.org .

Home environment influences child health, but the impact varies as children move into adolescence. The Family Nutrition and Physical Activity (FNPA) screening tool has been used to evaluate home environments, but studies have not compared the utility of the tool in different age groups. The purpose of this study was to examine the efficacy of the FNPA tool in first and tenth grade samples. Parents of first grade (n = 250) and tenth grade (n = 99) students completed the FNPA and results were linked to body mass index (BMI) data. FNPA scores were examined by gender, income, race, and school-level socioeconomic status (SES). Correlations examined associations between FNPA scores and several BMI indicators. Logistic and linear regression analyses evaluated the construct validity of the FNPA in both groups. Mean FNPA score differed by age group, by SES in both age groups, and by race in the first grade sample only. Correlations between FNPA score and BMI indicators were higher in the first grade sample, but SES was significantly associated with BMI only in tenth graders. The FNPA has stronger utility in younger children, while school SES is a stronger predictor of adolescent weight status.

To assess the role of sexual orientation and gender identity in the relationship between physical activity (PA), stress and resilience. A nationally-representative sample of students (n = 91,718) from United States postsecondary institutions. Students reported aerobic and strength training (ST) behaviors, stress, resilience, gender identity and sexual orientation. Moderated regressions examined the influence of gender identity and sexual orientation on the relationship between PA and stress or resilience. Men and heterosexual students reported higher PA and resilience and lower stress than did women, gender minorities, and sexual minorities. Significant moderation was found for women, queer students, bisexual students, trans women and lesbians in the various models. Gender minority and sexual minority students display poorer levels of PA and mental health than cisgender and heterosexual counterparts, but this relationship varies by identity group.
