BACKGROUND
Exposure to secondhand smoke (SHS) might be associated with obesity in children. This study aimed to evaluate whether continuous, quit, or start exposure to SHS was associated with obesity risk in early adolescents.
METHODS
We used population-based longitudinal data of primary school students in Adachi City, Tokyo, Japan, in 2018 (4th grade) and 2020 (6th grade) and studied 3605 students. The association between continuous, quit, start, or never exposed to SHS from 4th to 6th grade and BMI categories (underweight or normal weight, overweight, obesity) in 6th grade was investigated using ordinal logistic regression models.
RESULTS
Continuous SHS group showed a higher risk of being in the high BMI category than no SHS group (OR = 1.51, 95% CI 1.16-1.96). The stratified analyses by sex showed a similar association in boys (OR = 1.74, 95% CI 1.25-2.44) but not in girls (OR = 1.14, 95% CI 0.74-1.76). Quitting SHS group did not show a higher risk of being in the high BMI category than no SHS group (OR = 1.11, 95% CI 0.75-1.66) and the same was true for boys (OR 1.46, 95% CI 0.88-2.41).
CONCLUSIONS
Continuous SHS was a risk factor for obesity in boys in early adolescence; however, quitting SHS may help prevent it.
IMPACT
Continuous secondhand smoke (SHS) was not associated with a higher risk of obesity in early adolescence in girls. Continuous SHS can be a risk factor for obesity in early adolescence in boys. Quitting SHS may help to prevent obesity in early adolescence in boys.
背景
接触二手烟（SHS）可能与儿童肥胖有关。本研究旨在评估连续、戒烟或开始接触 SHS 是否与青少年早期肥胖风险相关。
方法
我们使用了日本东京足立区小学生的基于人群的纵向数据，于 2018 年（4 年级）和 2020 年（6 年级）进行研究，共纳入 3605 名学生。使用有序逻辑回归模型，研究了从 4 年级到 6 年级期间连续、戒烟、开始或从未接触 SHS 与 6 年级 BMI 类别（体重不足或正常体重、超重、肥胖）之间的关系。
结果
与无 SHS 组相比，持续接触 SHS 组处于高 BMI 类别的风险更高（OR=1.51，95%CI 1.16-1.96）。按性别分层分析显示，这种关联在男孩中相似（OR=1.74，95%CI 1.25-2.44），但在女孩中不相似（OR=1.14，95%CI 0.74-1.76）。戒烟组与无 SHS 组相比，处于高 BMI 类别的风险并未增加（OR=1.11，95%CI 0.75-1.66），男孩也如此（OR 1.46，95%CI 0.88-2.41）。
结论
在青少年早期，持续接触 SHS 是肥胖的危险因素；然而，戒烟可能有助于预防肥胖。
意义
在女孩中，持续接触 SHS 与肥胖风险增加无关。持续接触 SHS 可能是青少年早期男孩肥胖的一个危险因素。戒烟可能有助于预防青少年早期男孩肥胖。
