The obesity epidemic is dynamic with varying secular trends and differences between countries and ethnic groups. The objective of this study was to describe the age- and sex-specific longitudinal changes in weight and waist circumference in a rural Norwegian population with a high proportion of the indigenous Sami population. Based on two population-based surveys, SAMINOR 1 (2003-2004) and SAMINOR 2 (2012-2014), we present longitudinal changes in weight and waist circumference according to age at baseline in the SAMINOR 1 Survey and sex during the 10-year period. The analyses included 1538 men and 1958 women aged 36 to 69 at baseline (birth year 1934 to 1967). Forty-one percent of the population were Sami. Both weight and waist circumference were measured. The mean weight increased 0.8 kg (95% confidence interval: 0.5, 1.1) in men and 0.3 kg (95% confidence interval: 0, 0.5) in women. In both men and women, younger individuals gained significantly more weight during the 10-year follow-up than older participants (p < 0.001). The mean weight showed a statistically significant increase in men aged 36-54 and women aged 36-49 at baseline and was statistically significantly reduced in men and women aged 60-69. The mean waist circumference increased by 6.3 cm (95% confidence interval: 6.0, 6.6) in men and 8.4 cm (95% confidence interval 8.1, 8.8) in women. The mean waist circumference increased statistically significantly from SAMINOR 1 to SAMINOR 2 in all age groups, and there was an inverse relationship between age at baseline and change in waist circumference (p < 0.001). Waist circumference increased more than can be explained by changes in weight and age during the 10-year period. The inverse relationships between age at baseline in SAMINOR 1 and the 10-year change in weight and waist circumference were found in both Sami and non-Sami participants. The findings underline the need for prevention of obesity, particularly in younger people, as it is difficult to achieve permanent weight loss.
肥胖症是动态的，具有不同的长期趋势和国家及种族群体之间的差异。本研究的目的是描述一个农村挪威人群中，体重和腰围的年龄和性别特异性纵向变化，该人群中土著萨米人群的比例较高。基于两项基于人群的调查，SAMINOR 1（2003-2004 年）和 SAMINOR 2（2012-2014 年），我们根据 SAMINOR 1 调查中基线时的年龄和 10 年内的性别呈现体重和腰围的纵向变化。分析包括 1538 名 36 至 69 岁的男性和 1958 名女性（出生年份为 1934 年至 1967 年）。人口中有 41%是萨米人。均测量体重和腰围。男性体重增加 0.8 公斤（95%置信区间：0.5,1.1），女性增加 0.3 公斤（95%置信区间：0,0.5）。在男性和女性中，较年轻的个体在 10 年随访期间体重增加明显多于年龄较大的参与者（p<0.001）。在基线时年龄为 36-54 岁的男性和年龄为 36-49 岁的女性中，体重的平均值显示出统计学上显著的增加，而在年龄为 60-69 岁的男性和女性中，体重的平均值则统计学上显著降低。男性腰围增加 6.3 厘米（95%置信区间：6.0,6.6），女性腰围增加 8.4 厘米（95%置信区间：8.1,8.8）。在所有年龄组中，从 SAMINOR 1 到 SAMINOR 2 的平均腰围均呈统计学显著增加，并且在基线时的年龄与腰围变化之间呈反比关系（p<0.001）。在 10 年期间，腰围的增加超过了体重和年龄变化的解释。在萨米人和非萨米参与者中，均发现 SAMINOR 1 中的基线年龄与体重和腰围 10 年变化之间存在反比关系。这些发现强调了预防肥胖的必要性，特别是在年轻人中，因为很难实现永久性减肥。
