To estimate the prevalence of overweight, obesity, and thinness among Norwegian 13-year-olds and the changes from childhood (age 8 years) to adolescence (age 13 years); and to explore associations with sex, region, and population density from childhood to adolescence.
We used longitudinal, anthropometric data collected by school health nurses conducted in Norway. Weight status was classified according to the International Obesity Task Force cut-offs for overweight, obesity, and thinness, and according to mean body mass index (kg/m2).
The Norwegian Youth Growth Study, consisting of a nationally representative sample of Norwegian 13-year-olds (n = 1852; 50.7% girls), which is a part of The Norwegian Growth Cohort.
Among 13-year-old Norwegians, the prevalence of overweight (including obesity), obesity, and thinness was 15.8%, 2.5%, and 7.3%, respectively. There was little evidence that these had changed from 8 to 13 years. From 8 to 13 years, the odds of obesity was highest in the Northern region of Norway compared to the South-East (odds ratio (OR): 3.78 (95% confidence interval (CI): 1.13, 12.65; p = 0.036) and in rural areas (OR: 4.76 (95% CI: 1.52, 14.90; p = 0.027). Over the same age period, girls had a trend towards a higher odds of thinness compared to boys (OR: 1.65 (95% CI: 0.98, 2.78; p = 0.057).
In Norway, the prevalence of overweight, obesity, and thinness among 13-year-olds seem to be established by age 8 years. The prevalence of obesity was higher in the North and in rural areas. The results indicate the continued need for early prevention and treatment, and targeted interventions to certain areas.
估计挪威 13 岁儿童超重、肥胖和消瘦的流行率，并从儿童期（8 岁）到青春期（13 岁）评估其变化情况；探讨从儿童期到青春期，性别、地区和人口密度与这些变化的相关性。
我们使用由挪威学校保健护士进行的纵向、人体测量数据。体重状况根据国际肥胖工作组（International Obesity Task Force）的超重、肥胖和消瘦标准进行分类，并根据平均体重指数（kg/m2）进行分类。
挪威青少年生长研究（Norwegian Youth Growth Study），由挪威 13 岁青少年的全国代表性样本（n=1852；50.7%为女孩）组成，是挪威生长队列的一部分。
在挪威 13 岁青少年中，超重（包括肥胖）、肥胖和消瘦的流行率分别为 15.8%、2.5%和 7.3%。从 8 岁到 13 岁，与东南部相比，挪威北部地区肥胖的几率最高（优势比（odds ratio，OR）：3.78（95%置信区间（confidence interval，CI）：1.13，12.65；p=0.036）；与农村地区相比（OR：4.76（95% CI：1.52，14.90；p=0.027）。在同一时期，与男孩相比，女孩消瘦的几率呈上升趋势（OR：1.65（95% CI：0.98，2.78；p=0.057）。
在挪威，8 岁时 13 岁儿童超重、肥胖和消瘦的流行率似乎已经确定。北部和农村地区的肥胖患病率较高。结果表明，需要继续对某些地区采取早期预防和治疗以及有针对性的干预措施。
