This study explores the association between socioeconomic deprivation and five factors associated with long-term risk of cancer, in adolescents.
BMI, fat intake, fruit and vegetable intake, smoking, and exercise were assessed in 4320 students ages 11 to 12, from 36 schools, in the first year of a 5-year longitudinal study of the development of health behaviors (HABITS study). Neighborhood socioeconomic deprivation for each student's area of residence was matched to their postcode (zip code). We used multiple logistic regression analyses to investigate the relationship between risky behaviors and socioeconomic circumstances.
Univariate analyses showed boys and girls from more deprived neighborhoods were more likely to have tried smoking, to eat a high fat diet, and to be overweight. Girls living in more deprived areas were also less likely to eat five servings of fruit and vegetables or to exercise at the weekend. Most differences persisted after controlling for ethnicity. A clear deprivation gradient emerged for each risk factor, indicating the linear nature of the relationship.
This study demonstrates the influence of deprivation on engaging in cancer-risk health behaviors. These patterns may set young people from more socioeconomically deprived social environments on a trajectory leading to increased cancer mortality in adult life.
本研究探讨了青少年社会经济剥夺与五个与癌症长期风险相关因素之间的关联。
在一项为期5年的健康行为发展纵向研究（HABITS研究）的第一年，对来自36所学校的4320名11至12岁学生进行了体重指数、脂肪摄入量、水果和蔬菜摄入量、吸烟及运动情况的评估。将每名学生居住地区的邻里社会经济剥夺情况与其邮政编码相匹配。我们使用多元逻辑回归分析来研究危险行为与社会经济状况之间的关系。
单因素分析显示，来自贫困社区的男孩和女孩更有可能尝试吸烟、食用高脂肪饮食以及超重。生活在更贫困地区的女孩在周末吃五份水果和蔬菜或进行锻炼的可能性也较小。在控制种族因素后，大多数差异仍然存在。每个风险因素都出现了明显的剥夺梯度，表明这种关系呈线性。
本研究证明了剥夺对从事有癌症风险的健康行为的影响。这些模式可能会使来自社会经济更贫困社会环境的年轻人走上一条导致成年后患癌症死亡率增加的道路。
