The aim of this study was to examine body mass index and the prevalence of overweight and obesity in 1990 and 2001 in Oslo and Lofoten, Norway.
A randomly selected study population of 1,924 individuals (OsLof) underwent a structured personal interview in 1990. In 2001, 1629 individuals underwent the same interview. These samples were analysed as two cross-sectional datasets.
Overall mean BMI in 1990 was 24.7 for men and 22.9 for women, increasing significantly in 2001 to 26.1 and 24.6, respectively. In 1990, 37% of men and 20% of women were overweight, while 5% of men and 4% of women were obese. The corresponding figures for 2001 were 48% and 27% for overweight, and 12% and 11% for obesity, respectively.
The greatest increases in average BMI occurred for the youngest (18-34 years) for both genders and geographic regions. In 1990, urban-rural differences existed for mean BMI and proportion overweight for both genders, although geographic differences persisted only for women 10 years later.
本研究旨在调查1990年和2001年挪威奥斯陆和罗弗敦群岛的体重指数以及超重和肥胖的患病率。
1990年，对随机选取的1924名个体（奥斯陆-罗弗敦群岛研究对象）进行了结构化的个人访谈。2001年，1629名个体接受了相同的访谈。这些样本作为两个横断面数据集进行分析。
1990年男性总体平均体重指数为24.7，女性为22.9，2001年显著上升至分别为26.1和24.6。1990年，37%的男性和20%的女性超重，而5%的男性和4%的女性肥胖。2001年超重的相应数字分别为48%和27%，肥胖的相应数字分别为12%和11%。
两个性别和地理区域中，最年轻的人群（18 - 34岁）平均体重指数增长幅度最大。1990年，男性和女性的平均体重指数及超重比例存在城乡差异，不过10年后地理差异仅在女性中持续存在。
