Physical inactivity is a serious public health concern in adolescents from low- and middle-income countries (LMICs). Despite this, only a few multinational studies has investigated correlates of physical activity (PA) in young adolescents in this part of the world. In this study, we identified physical activity correlates using data from the Global school-based Student Health Survey. In total, 142,118 adolescents from 48 LMICs (age 13.8 ± 1.0 years; 49% girls) were included in the analyses. PA was assessed by the PACE+ Adolescent Physical Activity Measure and participants were dichotomised into those who do (60 min of moderate-vigorous PA every day of the week) and do not comply with the World Health Organization recommendations. We used multivariable logistic regression in order to assess the correlates. The prevalence of low PA was 15.3% (95%CI = 14.5%-16.1%). Boys (OR = 1.64; 95%CI = 1.47-1.83) and those who participated in physical education for ≥5 days/week (OR = 1.12; 95%CI = 1.10-1.15) were more likely to meet PA guidelines, while adolescents with food insecurity (OR = 0.85; 95%CI = 0.80-0.90), low fruit and vegetable intake (OR = 0.68; 95%CI = 0.63-0.74), low parental support/monitoring (OR = 0.68; 95%CI = 0.62-0.74), no friends (OR = 0.80; 95%CI = 0.72-0.88), and who experienced bullying (OR = 0.93; 95%CI = 0.86-0.99) were less likely to have adequate levels of PA. There were a few variations in the correlates depending on country-income level. Our data indicate that in adolescents aged 12 to 15 years living in LMICs physical activity participation is a complex and multi-dimensional behavior determined by sociocultural, socio-economic, and policy-related factors. Longitudinal research is needed to confirm/refute the present findings.
身体活动不足是中低收入国家（LMICs）青少年的一个严重公共卫生问题。尽管如此，在世界范围内，只有少数跨国研究调查了青少年身体活动的相关因素。在这项研究中，我们使用全球学生健康调查的数据来确定身体活动的相关因素。共有来自 48 个 LMICs 的 142118 名青少年（年龄 13.8±1.0 岁；49%为女孩）参与了分析。身体活动通过 PACE+青少年身体活动测量来评估，参与者被分为每天进行 60 分钟中高强度身体活动的遵守组和不遵守世界卫生组织建议的不遵守组。我们使用多变量逻辑回归来评估相关因素。低身体活动的患病率为 15.3%（95%CI=14.5%-16.1%）。男孩（OR=1.64；95%CI=1.47-1.83）和每周参加体育教育≥5 天的青少年（OR=1.12；95%CI=1.10-1.15）更有可能符合身体活动指南，而食物不安全的青少年（OR=0.85；95%CI=0.80-0.90）、水果和蔬菜摄入量低的青少年（OR=0.68；95%CI=0.63-0.74）、父母支持/监督少的青少年（OR=0.68；95%CI=0.62-0.74）、没有朋友的青少年（OR=0.80；95%CI=0.72-0.88）和遭受欺凌的青少年（OR=0.93；95%CI=0.86-0.99）更不可能有足够的身体活动水平。不同国家的收入水平对相关因素也存在一些差异。我们的数据表明，在年龄为 12 至 15 岁的中低收入国家青少年中，身体活动参与是一种复杂的多维行为，受社会文化、社会经济和政策相关因素的影响。需要进行纵向研究来证实/反驳目前的发现。
