Physical inactivity is a major public health concern because it is a determinant of obesity and obesity-related chronic diseases. Few longitudinal studies have examined the association between neighborhood socioeconomic (SES) environment and change in physical activity behaviors. Additionally, few studies have examined this association in immigrant groups or Hispanic subgroups such as Cubans. This research aimed to determine if neighborhood SES is associated with longitudinal change in moderate-to-vigorous physical activity (MVPA) among Cuban immigrants who participate in the Cuban Health Study in Miami, Florida. Data on 280 participants [mean age: 37.4 (± 4.6), 48.9% women, mean body mass index: 25.0 (± 2.5)] collected at baseline, 12 months and 24 months were analyzed. Minutes of MVPA were objectively measured during each data collection period using accelerometers. A neighborhood SES score was calculated for each participant's residential census tract from American Community Survey data on median household income, median housing value, educational attainment and occupation. The neighborhood SES score was grouped into tertiles, reflecting low, moderate and high neighborhood SES environment. Multilevel linear models were used to examine the relationship between neighborhood SES and change in MVPA over 24 months. At baseline, 94 (33.6%), 108 (38.6%) and 78 (27.9%) participants resided in low, moderate, and high SES neighborhoods, respectively. After adjusting for age, sex, and body mass index, no difference in average change in MVPA over time was observed between participants residing in low and moderate SES neighborhoods (=0.48) or low and high SES neighborhoods (=0.62). In Cuban immigrants, longitudinal change in MVPA may not vary by neighborhood socioeconomic environment.
缺乏身体活动是一个重大的公共卫生问题,因为它是肥胖及肥胖相关慢性病的一个决定因素。很少有纵向研究考察邻里社会经济(SES)环境与身体活动行为变化之间的关联。此外,很少有研究在移民群体或西班牙裔亚群体(如古巴人)中考察这种关联。本研究旨在确定邻里SES是否与参与佛罗里达州迈阿密古巴健康研究的古巴移民中至剧烈身体活动(MVPA)的纵向变化相关。分析了在基线、12个月和24个月时收集的280名参与者的数据[平均年龄:37.4(±4.6)岁,48.9%为女性,平均体重指数:25.0(±2.5)]。在每个数据收集期间使用加速度计客观测量MVPA的分钟数。根据美国社区调查关于家庭收入中位数、住房价值中位数、教育程度和职业的数据,为每个参与者的居住普查区计算邻里SES分数。邻里SES分数被分为三分位数,反映低、中、高邻里SES环境。使用多水平线性模型考察邻里SES与24个月内MVPA变化之间的关系。在基线时,分别有94名(3
