以往关于中低收入国家人口迁移的研究在试验设计和患者特征方面大不相同,难以就迁移对心血管病风险的影响达成一致性结论。目前尚不知这种迁移对各种心血管风险因子的影响是否一致。研究者假设迁移人口与居住在乡村的人口相比有 Previous research on population migration in low- and middle-income countries has been very different in terms of pilot design and patient characteristics, making it difficult to reach a conclusive conclusion about the impact of migration on the risk of cardiovascular disease. It is unknown whether the impact of such relocation on various cardiovascular risk factors is consistent. The researchers hypothesized that migrants were compared to those living in rural areas
