Data on the prevalence of obesity in elderly population in Spain are scarce. The objective of this work was to describe the prevalence of obesity and the related factors in a random sample of Spanish population aged 60 years-old or more, stratified by autonomous communities.
We analyzed the PREV-ICTUS study, a population-based study carried out between September and December 2005 in a random sample stratified by autonomous communities according to the census of inhabitants and the habitat in each community. Subjects were classified as with normal weight (body mass index [BMI] < 25 kg), overweight (BMI 25-29.9) and obesity (BMI > or = 30 kg).
In 6,843 subjects -mean age (standard deviation): 71.9 (7.1) years-old; 53.3% women-, prevalence of obesity was 34.5% (95% confidence interval [CI], 33.3-35.5%), higher in women (38.4%; 95% CI, 36.8-39.9%) than in men (30.0%; 95% CI, 28.4-31.6%; p < 0.001), with a tendency to decrease in the older population. In total, 81.7% of the population showed overweight (BMI > or = 25). Prevalence differed among communities from 46.4% to 20.7% (p < 0.001). In the multivariate analysis, obesity was inversely related to age (odds ratio [OR] = 0.98 per each year increment), and directly to female gender (OR = 1.25), rural (OR = 1.50) or semi-urban habitat (OR = 1.38), sedentary lifestyle (OR = 1.86) and non-smoking history (OR = 1.19).
Obesity was present in one out of 3 individuals of this reasonably representative sample of the Spanish population in an age range, 60 years-old or more, which concentrates a high cardiovascular risk. Differences in the prevalence among autonomus communities were detected.
西班牙老年人群肥胖患病率的数据较为匮乏。本研究的目的是描述西班牙60岁及以上随机抽样人群中肥胖的患病率及其相关因素，并按自治区进行分层。
我们分析了PREV-ICTUS研究，这是一项基于人群的研究，于2005年9月至12月进行，根据各社区的居民人口普查和居住情况，按自治区对随机样本进行分层。受试者被分为体重正常（体重指数[BMI]<25kg）、超重（BMI 25-29.9）和肥胖（BMI≥30kg）。
在6843名受试者中——平均年龄（标准差）：71.9（7.1）岁；女性占53.3%——肥胖患病率为34.5%（95%置信区间[CI]，33.3-35.5%），女性（38.4%；95%CI，36.8-39.9%）高于男性（30.0%；95%CI，28.4-31.6%；p<0.001），且在老年人群中有下降趋势。总体而言，81.7%的人群超重（BMI≥25）。各社区患病率在46.4%至20.7%之间存在差异（p<0.001）。在多变量分析中，肥胖与年龄呈负相关（每年增加的比值比[OR]=0.98），与女性性别（OR=1.25）、农村（OR=1.50）或半城市居住环境（OR=1.38）、久坐不动的生活方式（OR=1.86）和无吸烟史（OR=1.19）呈正相关。
在这个年龄在60岁及以上、具有较高心血管疾病风险的西班牙人群的合理代表性样本中，每3个人中就有1人肥胖。各自治区患病率存在差异。
