To describe the determinants of 12-year weight change among middle-aged women in Sweden.
In 1991/1992, 49,259 women across Sweden were recruited into a cohort. In 2003, 34,402 (73%) completed follow-up. Lifestyle and health characteristics including weight were collected, and 12-year weight change and substantial weight gain (≥+5.0 kg) were calculated; association between baseline characteristics and odds ratios (OR) with 95% confidence intervals (CI) of substantial weight gain were estimated.
During the 12-year follow-up, 81% of women experienced weight gain. Being above average weight (64.5 kg) at baseline (OR =1.20, 95% CI: 1.14-1.26) and smoking 1 to 9 (OR = 1.10, 95% CI: 1.01-1.20), 10 to 19 (OR = 1.30, 95% CI: 1.21-1.39), or ≥20 cigarettes daily (OR = 1.17, 95% CI: 1.04-1.32) increased a woman's odds of experiencing substantial weight gain (influenced by smoking cessation). In contrast, risk of substantial weight gain was reduced among women 45 to 50 years of age (OR = 0.79, 95% CI: 0.73-0.85), women reporting high alcohol consumption (OR = 0.90, 95% CI: 0.83-0.98), and those with medium (OR = 0.93, 95% CI: 0.87-1.00) or high (OR 0.83, 95% CI: 0.77-0.90) physical activity levels.
The majority of women experienced weight gain during middle age. Population-specific determinants of weight gain should guide obesity prevention efforts.
描述瑞典中年女性 12 年体重变化的决定因素。
1991/1992 年，瑞典各地招募了 49259 名女性进入队列。2003 年，34402 名（73%）完成了随访。收集了生活方式和健康特征，包括体重，并计算了 12 年体重变化和体重明显增加（≥+5.0kg）；估计了基线特征与体重明显增加的比值比（OR）及其 95%置信区间（CI）之间的关联。
在 12 年的随访期间，81%的女性体重增加。基线时超重（64.5kg）（OR=1.20，95%CI：1.14-1.26）和吸烟 1-9（OR=1.10，95%CI：1.01-1.20），10-19（OR=1.30，95%CI：1.21-1.39）或每天≥20 支香烟（OR=1.17，95%CI：1.04-1.32）增加了女性体重明显增加的几率（受戒烟影响）。相比之下，45-50 岁的女性（OR=0.79，95%CI：0.73-0.85）、报告高酒精摄入量的女性（OR=0.90，95%CI：0.83-0.98）以及中等（OR=0.93，95%CI：0.87-1.00）或高（OR 0.83，95%CI：0.77-0.90）体力活动水平的女性体重明显增加的风险降低。
大多数女性在中年时体重增加。体重增加的特定人群决定因素应指导肥胖预防工作。
