To study the changes in body mass index (BMI) in a population-based cohort and their relationship with sociodemographic variables in a Mediterranean-country.
A prospective population-based cohort with 8-year follow-up. The data used derive from the Cornellà-Health-Interview Survey Follow-up (CHIS.FU). 1008 people aged > or = 20 years (females=508; males=500) were interviewed in 1994 and in 2002, providing self-reported weight and height data. The BMI was compared using the Wilcoxon test for paired data. Changes in the BMI were calculated and their relationship with sociodemographic-variables and lifestyles using multivariate Breslow-Cox regression.
28.1% of participants had changed from normal-BMI in 1994 to overweight in 2002 (women=25.6%; men=31.6%). 16.8% increased from overweight to obesity (women=25.8%; men=11.2%). The cumulative incidence of overweight: women=26.4%; men=34.0%. The cumulative incidence of obesity: women=29.9%; men=13.1%. The cumulative age and sex-adjusted incidence of overweight showed a significant relationship with marital-status (married: RR=2.0; 95% CI: 1.2-3.4, divorced/widowed: RR=4.0; 95% CI: 1.7-9.3) and moderate alcohol-consumption (RR=1.86; 95% CI: 1.1-3.1). We observed a decreased age-adjusted risk in the incidence of obesity for men (RR=0.49; 95% CI: 0.3-0.8).
The observed changes in the increase in the incidence of obesity and overweight indicated a similar evolution in the obesity epidemic regardless of Mediterranean dietary patterns in our population.
研究人群中体重指数（BMI）的变化及其与地中海国家社会人口变量的关系。
这是一项具有 8 年随访的前瞻性人群队列研究。所使用的数据来源于 Cornellà-Health-Interview 调查随访（CHIS.FU）。1994 年和 2002 年对 1008 名年龄≥20 岁的人群（女性 508 人，男性 500 人）进行了访谈，提供了自我报告的体重和身高数据。使用配对数据的 Wilcoxon 检验比较 BMI。使用多变量 Breslow-Cox 回归计算 BMI 的变化及其与社会人口变量和生活方式的关系。
28.1%的参与者从 1994 年的正常 BMI 变为 2002 年的超重（女性 25.6%，男性 31.6%）。16.8%的人从超重变为肥胖（女性 25.8%，男性 11.2%）。超重的累积发病率：女性 26.4%，男性 34.0%。肥胖的累积发病率：女性 29.9%，男性 13.1%。年龄和性别调整后的超重累积发病率与婚姻状况（已婚：RR=2.0，95%CI：1.2-3.4；离婚/丧偶：RR=4.0，95%CI：1.7-9.3）和适度饮酒（RR=1.86，95%CI：1.1-3.1）显著相关。我们观察到男性肥胖发病率的年龄调整风险降低（RR=0.49，95%CI：0.3-0.8）。
肥胖和超重发病率的增加表明，无论我们人群的地中海饮食模式如何，肥胖流行的演变是相似的。
