To examine socioeconomic differences in obesity using several different socioeconomic indicators, ranging from childhood socioeconomic environment and adult socioeconomic status to material resources and economic satisfaction.
The data derived from the Helsinki Health Study baseline surveys in 2000 and 2001. Respondents to postal surveys were middle-aged employees of the City of Helsinki (4,975 women and 1,252 men, response rate 68%). Associations between eight socioeconomic indicators and obesity (BMI > or = 30 kg/m(2)), calculated from self-reported data, were examined by fitting a series of logistic regression models.
In women, all socioeconomic indicators except household income and economic satisfaction were associated with obesity. Parental education and childhood economic difficulties, i.e., socioeconomic conditions in childhood, remained associated with obesity after adjusting for all indicators of current socioeconomic position. Indicators of adult socioeconomic status, own education and occupational class, were no longer associated with obesity when childhood socioeconomic conditions were adjusted for. Home ownership and economic difficulties were associated with obesity after full adjustments. In men, the findings paralleled those among women, but few associations reached statistical significance.
Obesity was associated with several dimensions of socioeconomic position. Childhood socioeconomic disadvantage was associated with obesity independently of the various indicators of current socioeconomic position. Associations between obesity and both educational level and occupational class disappeared after adjustment for other indicators of socioeconomic position. This suggests that the variation observed in the prevalence of obesity by these key socioeconomic indicators may reflect differences in the related material resources.
使用多种不同的社会经济指标来研究肥胖方面的社会经济差异，这些指标涵盖从儿童时期的社会经济环境、成人社会经济地位到物质资源和经济满意度。
数据来源于2000年和2001年赫尔辛基健康研究的基线调查。邮寄调查问卷的受访者是赫尔辛基市的中年雇员（4975名女性和1252名男性，回复率68%）。通过拟合一系列逻辑回归模型，研究了八项社会经济指标与肥胖（体重指数≥30kg/m²）之间基于自我报告数据计算得出的关联。
在女性中，除家庭收入和经济满意度外，所有社会经济指标均与肥胖有关。在对当前社会经济地位的所有指标进行调整后，父母的教育程度和儿童时期的经济困难，即儿童时期的社会经济状况，仍与肥胖有关。在对儿童时期的社会经济状况进行调整后，成人社会经济地位指标、自身教育程度和职业阶层与肥胖不再相关。在进行全面调整后，自有住房和经济困难与肥胖有关。在男性中，研究结果与女性相似，但很少有关联达到统计学显著性。
肥胖与社会经济地位的多个维度相关。儿童时期的社会经济劣势与肥胖有关，且独立于当前社会经济地位的各种指标。在对社会经济地位的其他指标进行调整后，肥胖与教育水平和职业阶层之间的关联消失。这表明这些关键社会经济指标所观察到的肥胖患病率差异可能反映了相关物质资源的差异。
