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. 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. LPA was common (32.5%) and associated with all SHRDs (sex-age-adjusted odds ratio saOR reaching 1.99, < .001) and depressive-symptoms duration (saOR 1.63 (< .05) and 2.11 (< .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, < .001). Ndw was similarly associated with all SHRDs and SHRDcn (sex-age-adjusted regression coefficient reaching -1.10 day/week, < .001). These results were robust when controlling for socioeconomic features (18%<contribution<51%). Physical activity is associated with SHRDs, and socioeconomic features have an elevated confounding role. Healthcare providers can detect/reduce SHRDs and consequently improve physical activity among adolescents and prevent physical inactivity in adulthood.
缺乏规律的身体活动（LPA）和每周进行体力活动>60 分钟/天（Ndw）的天数可能与整个生命过程中的学校健康相关困难（SHRDs）有关。本研究评估了这些关联以及社会经济特征（国籍、家庭结构、父母的教育/职业/收入）在青少年中的混杂作用。这项基于人群的横断面研究纳入了来自法国东北部的 1559 名中学生（10-18 岁，98%年龄在 16 岁以下，778 名男孩和 781 名女孩）。他们在一个多小时的教学期间完成了一份问卷，收集了过去 12 个月的 LPA 和过去 7 天的 Ndw（因变量），以及包括社会经济特征、SHRDs（过去年级重复、过去 12 个月一般健康状况/身体健康/心理健康/社会关系不佳、抑郁症状（以及发病年龄和发病持续时间）；注意到的 SHRDcn 数量）在内的风险因素。使用逻辑/线性回归模型分析数据。LPA 很常见（32.5%），与所有 SHRDs 相关（性别年龄调整优势比 saOR 达到 1.99，<.001）和抑郁症状持续时间相关（saOR 1.63（<.05）和 2.11（<.001），分别为 1-2 年和≥3 年，与无抑郁症状相比）。在 SHRDcn 与 LPA 之间发现了剂量效应关系（24.0、33.7、45.6 和 53.5%；saOR 1.59、2.58 和 3.43；对于 SHRDcn 1-2、3-4 和≥5，分别与 SHRDcn=0 相比，<.001）。Ndw 也与所有 SHRDs 和 SHRDcn 相关（性别年龄调整回归系数达到-1.10 天/周，<.001）。当控制社会经济特征（18%<贡献<51%）时，这些结果仍然稳健。身体活动与 SHRDs 相关，社会经济特征具有更高的混杂作用。医疗保健提供者可以发现/减少 SHRDs，从而提高青少年的身体活动水平，并防止成年人的身体不活动。
