We previously hypothesized that physical activity would decrease over time in new Cuban immigrants after reviewing previous research on the effects of acculturation on health behaviors such as physical activity. Acculturation, as defined as increasing number of years residing in the US, is linked to reduced physical activity and increased risk of chronic disease and among some immigrant populations (Ghaddar et al., 2010; Brewer & Kimbro, 2014). While 24 month data from the current study showed an average increase in BMI from baseline (mean=0.47; p<0.0001), an increase in MVPA was also observed. We suspect that the number of data assessment periods needed to observe statistically significant changes in physical activity behaviors by neighborhood SES level in the current study iib iiia inhibitors is longer than the number of data collection periods included in the current study. As stated before, research studies previously conducted on associations between neighborhood SES environment and physical activity behaviors have not focused on middle-aged Hispanic adults (Alves et al., 2013; Molnar et al., 2004; Pascual et al., 2007; Sallis et al., 2009; Carson et al., 2014; Shishehbor et al., 2008; Boone-Heinonen et al., 2010; Boone-Heinonen et al., 2011; Voorhees et al., 2009). Nevertheless, these studies provide some insight into how neighborhood SES and physical activity may be associated in Hispanics. Several cross-sectional studies did not report statistically significant findings. Carson et al. (2014) observed that neighborhood SES measures were not associated with self-reported physical activity in children or their parents (Carson et al., 2014). Voorhees et al. (2009) found that neighborhood SES was not associated with time spent in MVPA or BMI in a multiethnic population of adolescent girls (Voorhees et al., 2009). Some of the longitudinal studies conducted have observed significant findings. In addition to the study by Boon-Heinonen and colleagues that examined Non-Hispanic black and white adults, Shishehbor et al. (2008) reported that the odds of impaired physical activity was higher among young adults living in low SES neighborhoods compared to high SES neighborhoods (Shishehbor et al., 2008; Boone-Heinonen et al., 2011). More prospective studies are needed in order to delineate whether neighborhood SES influences physical activity behaviors in minority populations such as Hispanics. A myriad of assessment methods (e.g. environmental scans, indices, GIS-derived measures, self-report) have been employed to characterize built and SES environment (Brownson, Hoehner, & Day, 2009). Built environment studies often employ measures of proximity to certain environmental features (e.g. recreation centers), walkability, street connectivity, or the availability of various structural of components such as sidewalks, trails and green space. Several of these studies of observed significant associations between built environment measures and individual-level physical activity behaviors (Hirsch, Diez Roux, Moore, Evenson, & Rodriguez, 2014; Kelly et al., 2014; Lovasi, Neckerman, Quinn, Weiss, & Rundle, 2009; Saelens, Sallis, Black, & Chen, 2003; Wells & Yang, 2008). Saelens et al. (2003) and Kelly et al. (2014) both found Archean/Proterozoic Era walkability, mixed land use and street connectivity were associated with higher levels of physical activity (Kelly et al., 2014; Saelens et al., 2003). Hirsch et al. (2014) observed that study subjects who recently relocated to neighborhoods with a higher walkability score engaged in a significantly higher amount of physical activity per week (Hirsch et al., 2014). In 2010, Boone-Heinonen and colleagues examined the inter-relationships between GIS-derived built environment measures and SES environment characteristics using principal factor analysis and found that the built and SES environment constructs are significantly associated (Boone-Heinonen et al., 2010). These results suggest that future examinations of the role of neighborhood environment should be cognizant of how built environment and neighborhood SES measures are inter-related in the context of the outcome variable being studied.
