RESUMEN
OBJECTIVE: To estimate which risk factors (sociodemographic, lifestyle, and health conditions) are associated with overweight and obesity in Japanese-Brazilians. METHODS: This was a cross-sectional study carried out with Japanese-Brazilians living in the southern region of Brazil. Data were collected between March and December of 2016 through a household survey addressing sociodemographic characteristics, lifestyle, and health conditions. Data were analyzed by means of logistic regression considering 95% level of significance. RESULTS: A total of 542 Japanese-Brazilians with a mean age of 47.75 years were evaluated; 52.8% were eutrophic, 36.9% were overweight, and 10.3% were people with obesity. The following variables remained associated with overweight after adjustments; male gender (ORaj = 1.85, CI = 1.24-2.76), age range of 40-49 years (ORaj = 2.27, CI = 1.10-4.68), and 50 to 59 years (ORaj = 2.17, CI = 1.004-4.72), alcohol consumption (ORaj = 2.11, CI = 1.07-4.16), and presence of chronic disease (ORaj = 1.59, CI = 1.02-2.46). The following were independent factors associated with obesity: male gender (ORaj = 3.63, CI = 1.78-7.40), the presence of chronic disease (ORaj = 4.13, CI = 1.96-8.71), the age range of 30 to 39 years (ORaj = 4.74, CI = 1.65-13.64) and 40 to 49 years (ORaj = 2.89, CI = 1.05-7.95), and irregularly active lifestyle (ORaj = 2.73, CI = 1.12-6.69). CONCLUSION: The results of this study show that being a male in the age range of 30-49 years old, alcohol consumption, and presence of chronic disease are associated with overweight and obesity in Japanese-Brazilians.
RESUMEN
O55 is one of the most frequent enteropathogenic Escherichia coli (EPEC) O serogroups implicated in infantile diarrhea in developing countries. Multilocus enzyme electrophoresis analysis showed that this serogroup includes two major electrophoretic types (ET), designated ET1 and ET5. ET1 corresponds to typical EPEC, whilst ET5 comprises strains with different combinations of virulence genes, including those for localized adherence (LA) and diffuse adherence (DA). Here we report that ET5 DA strains possess a DA adhesin, designated EPEC Afa. An 11.6-kb chromosomal region including the DA adhesin operon from one O55:H(-) ET5 EPEC strain was sequenced and found to encode a protein with 98% identity to AfaE-1, an adhesin associated with uropathogenic E. coli. Although described as an afimbrial adhesin, we show that both AfaE-1 and EPEC Afa possess fine fibrillar structures. This is the first characterization and demonstration of an Afa adhesin associated with EPEC.
