HPV knowledge, HPV vaccine awareness and initiation among Hispanics: The role of language, information seeking, and information scanning

Background. Among Hispanics, the HPV vaccine has the potential to eliminate disparities in cervical cancer incidence and mortality but only if optimal rates of vaccination are achieved. Media can be an important information source for increasing HPV knowledge and awareness of the vaccine. Very little is known about how media use among Hispanics affects their HPV knowledge and vaccine awareness. Even less is known about what differences exist in media use and information processing among English- and Spanish-speaking Hispanics.^ Aims. Examine the relationships between three health communication variables (media exposure, HPV-specific information scanning and seeking) and three HPV outcomes (knowledge, vaccine awareness and initiation) among English- and Spanish-speaking Hispanics.^ Methods. Cross-sectional data from a survey administered to Hispanic mothers in Dallas, Texas was used for univariate and multivariate logistic regression analyses. Sample used for analysis included 288 mothers of females aged 8-22 recruited from clinics and community events. Dependent variables of interest were HPV knowledge, HPV vaccine awareness and initiation. Independent variables were media exposure, HPV-specific information scanning and seeking. Language was tested as an effect modifier on the relationship between health communication variables and HPV outcomes.^ Results. English-speaking mothers reported more media exposure, HPV-specific information scanning and seeking than Spanish-speakers. Scanning for HPV information was associated with more HPV knowledge (OR = 4.26, 95% CI = 2.41 - 7.51), vaccine awareness (OR = 10.01, 95% CI = 5.43 - 18.47) and vaccine initiation (OR = 2.54, 95% CI = 1.09 - 5.91). Seeking HPV-specific information was associated with more knowledge (OR = 2.27, 95% CI = 1.23 - 4.16), awareness (OR = 6.60, 95% CI = 2.74 - 15.91) and initiation (OR = 4.93, 95% CI = 2.64 - 9.20). Language moderated the effect of information scanning and seeking on vaccine awareness.^ Discussion. Differences in information scanning and seeking behaviors among Hispanic subgroups have the potential to lead to disparities in vaccine awareness.^ Conclusion. Findings from this study underscore health communication differences among Hispanics and emphasize the need to target Spanish language media as well as English language media aimed at Hispanics to improve knowledge and awareness.^

Comportamiento de coníferas bajo riego en Dique Yaucha : Mendoza, Argentina

La provincia de Mendoza, que se ubica en el Centro-Oeste de la República Argentina, posee una extensión de 150.830 km2. Prácticamente todas las actividades agropecuarias y forestales están concentradas en el 3% de su territorio que es posible irrigar. Al oeste, en el límite con la República de Chile, está la cadena montañosa que forma parte de la región fitogeográfica del Desierto Andino que se extiende por más de 500 km, con un ancho promedio de 100 km. El objetivo de este trabajo fue evaluar la supervivencia y el comportamiento de distintas especies de coníferas en zonas del piedemonte mendocino. Para ello se instaló una parcela experimental en el Dique Yaucha, ubicado en el Departamento de San Carlos a 34°00' S y 69°07' O, a una altura de 1213 msnm. Las especies del ensayo fueron: Pinus pinea L., Pinus halepensis Mill. y Cupressus arizonica Greene. Se llevaron plantas de aproximadamente 0,70 m de altura, que se instalaron a una distancia de plantación definitiva de 3 x 3 m y se regaron superficialmente por surcos. Se tomaron periódicamente datos dasométricos de diámetro altura de pecho (DAP) de todas las plantas, altura total de los árboles promedio de cada especie, registrándose además las fallas producidas y el estado sanitario. Los resultados obtenidos a la edad de 17 años son: Pinus pinea: diámetro promedio 17 cm, altura 6,60 m y 22,5% de fallas; Pinus halepensis: diámetro promedio 16 cm, altura 8,60 m y 12,2% de fallas; Cupressus arizonica: diámetro promedio 20 cm, altura 7,75 m y 18,1% de fallas. Es de destacar que P. pinea presenta el 6% de fustes bifurcados a baja altura. Todas las especies tienen un buen estado sanitario, no registrándose hasta la fecha plagas o enfermedades que hayan afectado el desarrollo del ensayo.
