Latino persons with chronic spine pain (CSP) face challenges engaging in physical activity (PA) and minimizing sedentary behavior (SB). This study aimed to objectively characterize PA and identify correlates of PA and SB in Latino persons with CSP. Cross-sectional baseline data from Latino participants who were enrolled in a clinical trial for CSP near the U.S.-Mexico border were utilized. Blockwise regression assessed the association between sociodemographic, clinical, interpersonal, and environmental factors with light PA (LPA), moderate-to-vigorous PA (MVPA), and SB. Participants (N = 154, Mage = 47.5 ± 12.1 years) spent 342.8 ± 111.6 min/day in LPA, 56.1 ± 71.1 min/day in MVPA, and 550.3 ± 140.9 min/day in SB. Seventy-five percent of participants met national PA guidelines. Lower income and higher pain interference were associated with lower LPA (R2 = 9%, p < .05). Younger age and lower income were associated with higher MVPA (R2 = 13%, p < .05). Lower income was associated with lower SB (R2 = 5%, p < .05). Younger age (OR 95% confidence interval [CI] [0.87, 0.98]) and higher exercise self-efficacy (OR 95% CI [1.06, 8.09]) increased the odds of meeting PA guidelines. Participants with CSP exhibited greater levels of LPA, MVPA, and SB compared with prior studies of Latino persons without pain. Sociodemographic variables including age and income were most consistently associated with PA and SB outcomes. Future research is needed to identify other relevant intrapersonal, interpersonal, and environmental determinants of PA and SB in this clinical population.

Obesity is a leading contributor to colorectal cancer risk. We investigated whether the risk variants identified in genome-wide association studies of body mass index (BMI) and waist size are associated with colorectal cancer risk, independently of the effect of obesity phenotype due to a shared etiology. Twenty-four single nucleotide polymorphisms (SNPs) in 15 loci (BDNF, FAIM2, FTO, GNPDA2, KCTD15, LYPLAL1, MC4R, MSRA, MTCH2, NEGR1, NRXN3, SEC16B, SH2B1, TFAP2B and TMEM18) were genotyped in a case-control study of 2,033 colorectal cancer cases and 9,640 controls nested within the multiethnic cohort study, as part of the population architecture using genomics and epidemiology consortium. Risk alleles for two obesity SNPs were associated with colorectal cancer risk--KCTD15 rs29941 [odds ratio (OR) for C allele = 0.90, 95% confidence interval (CI) 0.83-0.98; p = 0.01] and MC4R rs17782313 (OR for C allele = 1.12, 95% CI 1.02-1.22; p = 0.02). These associations were independent of the effect of BMI. However, none of the results remained significant after adjustment for multiple comparisons. No heterogeneity was observed across race/ethnic groups. Our findings suggest that the obesity risk variants are not likely to affect the risk of colorectal cancer substantially. Show less
