Abstract

OBJECTIVE

To determine whether changes in mean BMI and the prevalence of obesity in a total adult population during a short (11-year) period were associated with changes in the prevalence of diabetes.

RESEARCH DESIGN AND METHODS

This study involved cross-sectional surveys of all inhabitants aged > or = 20 years of the county of Nord-Trøndelag from 1984 to 1986 (n = 85,100) and from 1995 to 1997 (n = 92,434). Attendance rates were 88.1 and 71.3%, respectively, and 90.0% in an additional survey of people aged 13-19 years from 1995 to 1997 (n = 9,593). Main outcome measures were age-specific mean BMI for the diabetic and nondiabetic subgroups and the prevalence of obesity and diabetes. For comparison, mean BMIs from 18 of 19 Norwegian counties for the group aged 40-42 years were examined.

RESULTS

Mean BMI increased from 27.2 to 29.0 kg/m2 in the diabetic population and from 25.1 to 26.3 kg/m2 in the nondiabetic population. The BMI distribution curve shifted to the right, but homogeneity was also reduced. A comparison with other Norwegian counties indicated that this increase occurred during the last 6 years between the surveys. The prevalence of obesity (BMI > or = 30 kg/m2) increased from 7.5 to 14% in nondiabetic men and from 13 to 18% in nondiabetic women. The increase was particularly great in men aged < 60 years and in women aged < 50 years. The overall prevalence of known diabetes increased between the two surveys (from 2.9 to 3.2%) but only in men. The largest increase was observed in the corresponding younger sex and age-groups.

CONCLUSIONS

A substantial increase in mean BMI and the prevalence of obesity occurred in the younger age-groups at the same time as an increase in the prevalence of diabetes. A greater increase in diabetes prevalence in this ethnically stable Western European population may follow if effective primary preventive strategies are not undertaken.

摘要

目的

确定在较短（11年）时间内成年总人口的平均体重指数（BMI）变化及肥胖患病率变化是否与糖尿病患病率变化相关。

研究设计与方法

本研究涉及对北特伦德拉格郡所有年龄≥20岁居民的横断面调查，调查时间分别为1984年至1986年（n = 85,100）和1995年至1997年（n = 92,434）。参与率分别为88.1%和71.3%，在1995年至1997年对13 - 19岁人群进行的另一项调查中参与率为90.0%（n = 9,593）。主要观察指标为糖尿病亚组和非糖尿病亚组的年龄特异性平均BMI、肥胖患病率和糖尿病患病率。为作比较，还研究了挪威19个郡中18个郡40 - 42岁人群的平均BMI。

结果

糖尿病患者群体的平均BMI从27.2 kg/m²增至29.0 kg/m²，非糖尿病患者群体的平均BMI从25.1 kg/m²增至26.3 kg/m²。BMI分布曲线右移，但同质性也降低。与挪威其他郡比较表明，这种增加发生在两次调查期间的最后6年。非糖尿病男性的肥胖患病率（BMI≥30 kg/m²）从7.5%增至14%，非糖尿病女性从13%增至18%。在年龄<60岁的男性和年龄<50岁的女性中增加尤为显著。两次调查期间已知糖尿病的总体患病率有所增加（从2.9%增至3.2%），但仅在男性中增加。在相应的年轻性别和年龄组中增幅最大。
