Re-engagement of Early Adolescents with Severe School Issues in School/Professional Project Reduces School-Behavior-Health Problems

Association of School Health Relationship Difficulties with Lack of Regular Physical Activity in Younger Adolescents: A Population Based Study

Objective: Lack of regular physical activity (LPA) and the number of days/week with physical activity >60 minutes/day (Ndw) may be associated with school-health-relational difficulties (SHRDs) during the life-course. This study assessed their associations and the confounding role of socioeconomic features (nationality, family structure, parents' education/occupation/income) among younger adolescents. Methods: This cross-sectional population-based study included 1,559 middle-school adolescents from north-eastern France (10-18 years, 98% under 16 years, 778 boys and 781 girls). They completed over one-hour teaching period a questionnaire collecting last-12-month LPA and last-7-day Ndw (dependent variables), and risk factors including socioeconomic features, SHRDs (previous grade repetitions, last-12-month poor general health status/physical health/psychological health/social-relationships, depressive symptoms (and age at onset and duration from onset); cumulated number noted SHRDcn). Data were analyzed using logistic/linear regression models. Results: LPA was common (32.5%) and associated with all SHRDs (sex-age-adjusted odds ratio saOR reaching 1.99, p < .001) and depressive-symptoms duration (saOR 1.63 (p < .05) and 2.11 (p < .001) for 1-2 and ≥3 years, respectively, vs. no depressive symptoms). A dose-effect association was found between SHRDcn and LPA (24.0, 33.7, 45.6, and 53.5%; saOR 1.59, 2.58, and 3.43; for SHRDcn 1-2, 3-4, and ≥5 respectively, vs. SHRDcn = 0, p < .001). Ndw was similarly associated with all SHRDs and SHRDcn (sex-age-adjusted regression coefficient reaching -1.10 day/week, p < .001). These results were robust when controlling for socioeconomic features (18% Collapse

Association between untreated low back pain and injury proneness and confounding role of behavioral-health difficulties among younger adolescents: a population-based study

PURPOSE

Low back pain (LPB) is mostly left untreated (LBP_untreated) and may increase the injury risk due to associated behavioral-health difficulties (BHDs) among adolescents. This study assessed the association between LBP_untreated (vs. treated LBP (LBP_treated)) and injuries and the mediating role of BHDs among younger adolescents (10-16 years).

METHODS

This population-based study compared 328 adolescents with LBP_untreated (mean age = 13.7 ± 1.3) with 291 with LBP_treated (mean age = 13.3 ± 1.2) from north-eastern France. They completed a questionnaire collecting, at school-year end, socioeconomic features, LBP_treated/LBP_untreated, BHDs (alcohol/tobacco use, excessive screen-time, poor social support, poor physical health, depressive symptoms, and pain limiting activities), and injuries during the current school-year. Data were analyzed using multinomial logistic regression models and Kaplan-Meier estimates.

RESULTS

The proportion of subjects without alcohol/tobacco use or depressive symptoms decreased with time more quickly since age 10 among the adolescents with LBP_untreated than among those with LBP_treated. Hence, most LBP early started and the subjects with LBP_untreated had a higher risk of single injury (sex-age-class-level-socioeconomic-features-adjusted relative risk ratio RR = 1.63, p < 0.05, vs. LBP_treated) and a much higher risk of ≥ 2 injuries (RR = 2.60, p < 0.001). BHDs played a strong mediating role in the association between LBP_untreated and ≥ 2 injuries (contribution = 48%) but a modest mediating role in that between LBP_untreated and single injury (contribution = 10%) (pseudo R² = 7.6%).

CONCLUSION

LBP_untreated is common and associated with injuries partly due to BHDs (which may alter physical/mental capabilities, risk perception/awareness, and vigilance) among younger adolescents. Our results may inform healthcare providers that they can detect/treat LBP and BHDs to prevent their aggravation and injuries.
