背景 日本国家营养调查 (NNS-J) 提供了 50 多年来全国的年度人体测量信息。根据这项调查，日本男性和老年女性的平均体重指数（BMI）近几十年来有所增加，但年轻女性的平均体重指数有所下降。我们研究了出生队列对这一现象的影响。方法 我们分析了 NNS-J 中 20-69 岁受试者的数据。估算了 1956-2005 年期间的 BMI 以及 1976-2005 年期间超重和肥胖（BMI ≥ 25 kg/m2）的患病率。结果 每个出生队列的 BMI 都随着年龄的增长而增加，增量相似，直到 60-69 岁才达到峰值。然而，从横截面年龄来看，BMI 通常在 60-69 岁之前达到峰值。 20-29岁人群之间的差异已经存在，并且在20-29岁和30-39岁之间的男性中略有增加。从 1891-1900 年到 1971-80 年，所有男性年龄组的 BMI 均有所增加。然而，在女性中，这一数字在 1931-40 年间有所增加，但随后有所下降。患病率的变化通常与体重指数的变化一致。最近平均体重指数的增加（年轻女性的下降）可归因于出生队列，这表明较瘦（较胖）和较新出生的队列已被较胖（较瘦）的队列所取代。结论 根据重复的年度调查定量证明了队列效应。在日本，不同群体之间的体重指数差异在成年初期就已经存在。
Background The National Nutrition Survey, Japan (NNS-J) provides annual anthropometric information for a whole nation over 50 years. Based on this survey, the mean body mass index (BMI) of Japanese men and elderly women has increased in recent decades, but that of young women has decreased. We examined the effect of birth cohort on this phenomenon. Methods We analysed data from the NNS-J for subjects aged 20–69 years. BMI during 1956–2005 and the prevalence of overweight and obesity (BMI ≥ 25 kg/m2) during 1976–2005 were estimated. Results The BMI increased with age in every birth cohort, with similar increments, and did not peak until 60–69 years of age. However, with cross-sectional age, the BMI usually peaked before 60–69 years of age. The differences among cohorts already existed at 20–29 years of age, and slightly increased in men between 20–29 and 30–39 years of age. The BMI in all male age groups increased from the 1891–1900 through 1971–80 cohorts. However, in women, the figure increased until the 1931–40 cohorts, but later decreased. Changes in prevalence were generally consistent with changes in BMI. The recent increase (decrease in young women) in the mean BMI is attributable to birth cohort, indicating that thinner (fatter) and less recent birth cohorts have been replaced by fatter (thinner) ones. Conclusions A cohort effect was quantitatively demonstrated based on a repeated annual survey. In Japan, the differences in BMI among cohorts were already established by young adulthood.
