The aim of this study was to examine whether takeaway food consumption mediated (explained) the association between socioeconomic position and body mass index (BMI). A postal-survey was conducted among 1500 randomly selected adults aged between 25 and 64years in Brisbane, Australia during 2009 (response rate 63.7%, N=903). BMI was calculated using self-reported weight and height. Participants reported usual takeaway food consumption, and these takeaway items were categorised into "healthy" and "less healthy" choices. Socioeconomic position was ascertained by education, household income, and occupation. The mean BMI was 27.1kg/m(2) for men and 25.7kg/m(2) for women. Among men, none of the socioeconomic measures were associated with BMI. In contrast, women with diploma/vocational education (β=2.12) and high school only (β=2.60), and those who were white-collar (β=1.55) and blue-collar employees (β=2.83) had significantly greater BMI compared with their more advantaged counterparts. However, household income was not associated with BMI. Among women, the consumption of "less healthy" takeaway food mediated BMI differences between the least and most educated, and between those employed in blue collar occupations and their higher status counterparts. Decreasing the consumption of "less healthy" takeaway options may reduce socioeconomic inequalities in overweight and obesity among women but not men.
本研究的目的是检验外卖食品消费是否介导(解释)了社会经济地位与体重指数(BMI)之间的关联。2009年,在澳大利亚布里斯班对1500名年龄在25至64岁之间的成年人进行了一项邮政调查(回复率63.7%,N = 903)。BMI通过自我报告的体重和身高计算得出。参与者报告了通常的外卖食品消费情况,这些外卖食品被分为“健康”和“不太健康”两类选择。社会经济地位通过教育程度、家庭收入和职业来确定。男性的平均BMI为27.1kg/m²,女性为25.7kg/m²。在男性中,没有一项社会经济指标与BMI相关。相比之下,拥有文凭/职业教育(β = 2.12)和仅有高中学历(β = 2.60)的女性,以及白领(β = 1.55)和蓝领员工(β = 2.83)的BMI显著高于条件更优越的同龄人。然而,家庭收入与BMI无关。在女性中,“不太健康”的外卖食品消费介导了受教育程度最低和最高的女性之间,以及从事蓝领职业的女性与地位较高的同龄人之间的BMI差异。减少“不太健康”的外卖食品选择可能会减少女性超重和肥胖方面的社会经济不平等,但对男性则不然。
