许多国家都报道了城乡地区平均体重的差异，但尚不清楚这些差异是由于社会选择的影响还是社会因果关系造成的。我们研究了芬兰青少年体重指数 (BMI) 是否可以预测 21 年期间的选择性城市/农村迁移，以及同一时期的城市/农村生活是否可以预测芬兰从青春期到成年期 BMI 增长的差异。参与者来自前瞻性、基于人群的年轻芬兰人心血管风险研究 (n = 1787)，基线年龄为 12-18 岁，最终随访年龄为 33-39 岁，数据在六个随访阶段收集。支持社会选择，较重的青少年成年后迁移到城市地区的可能性较小：肥胖青少年在 33-39 岁时居住在城市地区的可能性是正常体重青少年的三分之一。支持社会因果关系的是，在研究期间，农村居住者预测从青春期到成年期的体重指数增长幅度高于城市居住者。这些关联与父母的社会经济地位和体重指数无关，也与参与者自己的教育水平、职业阶层、婚姻状况和父母身份无关。这些研究结果表明，生活在芬兰农村地区的人们体重较高可能是由于社会选择和社会因果机制造成的，即较重的人往往会迁移到人们往往会变得更重的农村地区。 (C) 2008 Elsevier Ltd. 保留所有权利。
Average body weight differences between urban and rural areas have been reported in many countries, but it is unknown whether these are due to effects of social selection or social causation. We examined whether adolescent body mass index (BMI) predicted selective urban/rural migration over a 21-year period and whether urban/rural living over the same period predicted differences in BMI increase from adolescence to adulthood in Finland. The participants were from the prospective, population-based Cardiovascular Risk in Young Finns study (n = 1787) aged 12-18 years at baseline and 33-39 years at the final follow-up, with data collected at six follow-up phases. Supporting social selection, heavier adolescents were less likely to migrate to urban areas as adults: in obese adolescents the likelihood of living in an urban area at 33-39 years age was one third of that in normal weight adolescents. Supporting social causation, rural residence over the study period predicted a greater increase in BMI from adolescence to adulthood than urban residence did. These associations were independent of parental socioeconomic status and BMI, and of participants' own educational level, occupational class, marital status, and parenthood status. Together the findings suggest that the higher body weight of people living in rural areas of Finland may be due to both social selection and social causation mechanisms, i.e. heavier people tend to migrate to more rural areas where people tend to get heavier.
