很少有研究检查了多项指标随时间的趋势，更少的研究检查了不同体重指数（BMI）组随时间的趋势。鉴于肥胖个体的死亡率普遍下降，但心血管风险因素增加，假设肥胖和多发性硬化症之间的关联趋势随着时间的推移而增加。我们研究的数据来自1996-97年全国人口健康调查以及2005年和2012-13年加拿大社区健康调查（所有3项调查的N = 277，366）。我们使用逻辑回归模型研究了BMI组与多发病之间的关联趋势。我们还调查了特定慢性病、慢性病对和不同BMI组多发病水平的患病率趋势。我们发现，与1996-97年相比，2005年（OR = 1.42; p < 0.001）和2012-13年（OR = 1.58; p < 0.001）的多聚体水平显著更高。与1996-97年相比，2012-13年II/III类（OR = 1.48; p = 0.005）和I类肥胖（OR = 1.38; p = 0.001）个体的多Morphin水平变化更大。在肥胖人群中，多发病率的增加主要是由于3+慢性疾病和高血压疾病的增加，而在肥胖老年人中增加最多。我们的研究结果强调了需要采取干预措施，以预防肥胖和预防肥胖患者，特别是老年人的慢性疾病。
Very few studies have examined trends in multimorbidity over time and even fewer have examined trends over time across different body mass index (BMI) groups. Given a general decline in death rates but increased cardiovascular risk factors among individuals with obesity, the trend in the association between obesity and multimorbidity is hypothesized to be increasing over time. The data for our study came from the 1996-97 National Population Health Survey and the 2005 and 2012-13 Canadian Community Health Surveys (N = 277,366 across all 3 surveys). We examined trends in the association between BMI groups and multimorbidity using a logistic regression model. We also investigated trends in the prevalence of specific chronic conditions, pairs of chronic conditions and different levels of multimorbidity across BMI groups. We found significantly greater levels of multimorbidity in 2005 (OR = 1.42; p < 0.001) and 2012-13 (OR = 1.58; p < 0.001) relative to 1996-97. Changes in multimorbidity levels were much greater among individuals with class II/III (OR = 1.48; p = 0.005) and class I obesity (OR = 1.38; p = 0.001) in 2012-13 relative to 1996-97. Much of the increase in multimorbidity among individuals living with obesity was due to increases in 3+ chronic conditions and conditions in combination with hypertension, and the greatest increase was found among seniors living with obesity. Our results highlight the need for interventions aimed at preventing obesity and the prevention of chronic conditions among individuals with obesity, especially among seniors.
