To investigate BMI-specific associations between health-related behaviours in early adolescence and the likelihood of overweight in mid-adolescence in a sample of Norwegian adolescents.
Longitudinal study of 393 adolescents recruited from schools in Telemark County, Norway. Parents reported baseline data on children's behavioural variables and background data (at age 12-13 years). Dietary data were reported by means of a retrospective FFQ. Eating patterns were identified using principal component analysis. Height and weight were measured at baseline and 3-year follow-up. BMI-specific differences in health-related behaviours (eating patterns, physical activity and screen time) at baseline were analysed using cross-tabulation and Pearson's χ 2 test (Fisher's test). Associations between early health-related behaviours and the likelihood of later overweight were examined using multiple logistic regression.
Primary and secondary schools, Telemark, Norway.
Children (n 393) in 7th grade (mean age 12·7 (sd 0·3) years), followed up in 10th grade, and parents.
A moderate to high intake of a varied Norwegian eating pattern combined with moderate-to-vigorous physical activity ≥1 h/d in the 7th grade were associated with a reduced likelihood of being overweight in the 10th grade, but only among already overweight adolescents (adjusted OR=0·2; 95 % CI 0·1, 1·0). Screen time of >3 h/d in the 7th grade was associated with an increased likelihood of subsequent overweight only among adolescents with an initial normal weight (adjusted OR=2·8; 95 % CI 1·1, 7·3).
BMI-specific associations were observed between health-related behaviours in early adolescence and the likelihood of being overweight in mid-adolescence.
在挪威青少年样本中,研究青春期早期与健康相关行为之间特定BMI值与青春期中期超重可能性之间的关联。
对从挪威泰勒马克郡学校招募的393名青少年进行纵向研究。父母报告了孩子行为变量的基线数据和背景数据(12至13岁时)。通过回顾性食物频率问卷报告饮食数据。使用主成分分析确定饮食模式。在基线和3年随访时测量身高和体重。使用交叉表和Pearson卡方检验(Fisher检验)分析基线时与健康相关行为(饮食模式、身体活动和屏幕时间)的特定BMI差异。使用多元逻辑回归检验早期与健康相关行为与后期超重可能性之间的关联。
挪威泰勒马克郡的中小学。
七年级学生(n = 393)(平均年龄12.7(标准差0.3)岁),随访至十年级,以及他们的父母。
七年级时适度到大量摄入多样化的挪威饮食模式并结合每天≥1小时的中度到剧烈身体活动,与十年级时超重可能性降低相关,但仅在已经超重的青少年中(调整后的比值比=0.2;95%置信区间0.1,1.0)。七年级时每天屏幕时间>3小时仅与初始体重正常的青少年随后超重的可能性增加相关(调整后的比值比=2.8;95%置信区间1.1,7.3)。
观察到青春期早期与健康相关行为之间特定BMI值与青春期中期超重可能性之间存在关联。
