To compare physical activity and sedentary behavior patterns of rural-to-urban migrants in Peru versus lifetime rural and urban residents and to determine any associations between low physical activity and four cardiovascular risk factors: obesity (body mass index > 30 kg/m²), systolic and diastolic blood pressure, hypertension, and metabolic syndrome.
The PERU MIGRANT (PEru's Rural to Urban MIGRANTs) cross-sectional study was designed to measure physical activity among rural, urban, and rural-to-urban migrants with the International Physical Activity Questionnaire (IPAQ).
The World Health Organization (WHO) age-standardized prevalence of low physical activity was 2.2% in lifetime rural residents, 32.2% in rural-to-urban migrants, and 39.2% in lifetime urban residents. The adjusted odds ratios for low physical activity were 21.43 and 32.98 for migrant and urban groups respectively compared to the rural group. The adjusted odds ratio for being obese was 1.94 for those with low physical activity. There was no evidence of an association between low physical activity and blood pressure levels, hypertension, or metabolic syndrome.
People living in a rural area had much higher levels of physical activity and lower risk of being overweight and obese compared to those living in an urban area of Lima. Study participants from the same rural area who had migrated to Lima had levels of physical inactivity and obesity similar to those who had always lived in Lima. Interventions aimed at maintaining higher levels of physical activity among rural-to-urban migrants may help reduce the epidemic of obesity in urban cities.
比较秘鲁城乡移民与终身农村和城市居民的体力活动和久坐行为模式，并确定体力活动水平低与四个心血管风险因素（肥胖症（体重指数> 30kg/m²）、收缩压和舒张压、高血压和代谢综合征）之间的任何关联。
PERU MIGRANT（秘鲁农村到城市移民）横断面研究旨在使用国际体力活动问卷（IPAQ）测量农村、城市和城乡移民的体力活动。
根据世界卫生组织（WHO）的年龄标准化标准，终身农村居民中体力活动水平低的患病率为 2.2%，城乡移民中为 32.2%，终身城市居民中为 39.2%。与农村组相比，移民组和城市组的体力活动水平低的调整后优势比分别为 21.43 和 32.98。体力活动水平低的人肥胖的调整后比值比为 1.94。体力活动水平低与血压水平、高血压或代谢综合征之间没有关联的证据。
与生活在利马市区的人相比，生活在农村地区的人体力活动水平更高，超重和肥胖的风险更低。从同一农村地区移民到利马的研究参与者的体力活动不足和肥胖程度与那些一直生活在利马的参与者相似。旨在维持城乡移民更高体力活动水平的干预措施可能有助于减少城市肥胖症的流行。
