“…CRELES is a longitudinal study based on a national sample of 2,827 residents of Costa Rica aged 60 and older in 2005, with oversampling of the oldest old (Rosero Bixby and others, 2010). The CRELES sample was selected from the 2000 census database using a multi -stage sampling design and complemented with a 100% sample of near-centenarians and centenarians of the Nicoya region that rendered 91 additional participants in this longitudinal study.…”

“…The mean age of the overall CRELES sample was 76 with a range from 60 to 109. The ability of the CRELES sample to provide unbiased descriptions of characteristics of elderly Costa Ricans and of their mortality has been assessed elsewhere (Rosero Bixby and others, 2010; Rosero-Bixby and Dow, 2009). The “Committee on Science and Ethics” of the University of Costa Rica approved the study, and all participants provided written informed consent.…”

Objectives Peripheral blood leukocyte telomere length is increasingly being used as a biomarker of aging, but its natural variation in human populations is not well understood. Several other biomarkers show seasonal variation, as do several determinants of leukocyte telomere length. We examined whether there was monthly variation in leukocyte telomere length in Costa Rica, a country with strong seasonal differences in precipitation and infection. Methods We examined a longitudinal population based cohort of 581 Costa Rican adults age 60 and above, from which blood samples were drawn between October 2006 and July 2008. Leukocyte telomere length was assayed from these samples using the quantitative PCR method. Multivariate regression models were used to examine correlations between month of blood draw and leukocyte telomere length. Results Telomere length from peripheral blood leukocytes varied by as much as 200 base pairs depending on month of blood draw, and this difference is not likely to be due to random variation. A moderate proportion of this association is statistically accounted for by month and region specific average rainfall. We found shorter telomere length associated with greater rainfall. Conclusions There are two possible explanations of our findings. First, there could be relatively rapid month-to-month changes in leukocyte telomere length. This conclusion would have implications for understanding the natural population dynamics of telomere length. Second, there could be seasonal differences in constituent cell populations. This conclusion would suggest that future studies of leukocyte telomere length use methods to account for the potential impact of constituent cell type.

Studies in humans suggest that leukocyte telomere length may act as a marker of biological aging. We investigated whether individuals in the Nicoya region of Costa Rica, known for exceptional longevity, had longer telomere length than those in other parts of the country. After controlling for age, age squared, rurality, rainy season and gender, mean leukocyte telomere length in Nicoya was substantially longer (81 base pairs, p<0.05) than in other areas of Costa Rica, providing evidence of a biological pathway to which this notable longevity may be related. This relationship remains unchanged (79 base pairs, p<0.05) after statistically controlling for nineteen potential biological, dietary and social and demographic mediators. Thus the difference in mean leukocyte telomere length that characterizes this unique region does not appear to be explainable by traditional behavioral and biological risk factors. More detailed examination of mean leukocyte telomere length by age shows that the regional telomere length difference declines at older ages.

Predictores socioemocionales y cognitivos: su papel en la comprensión del envejecimiento con éxito en el contexto costarricense. Universitas Psychologica, 16(1) RESUMENTomando en cuenta las teorías del envejecimiento con éxito, este estudio se orientó hacia la identificación y el análisis de las características que presentan personas adultas mayores con altos niveles de actividad y participación social residentes en Costa Rica. El estudio contó con 191 participantes con edades entre 55 y 87 años (M = 68.5, DE = 6.9) que habitan en el área metropolitana y participan en programas dirigidos a personas mayores en cursos de computación, idiomas, actividad física, arte, entre otros. Mediante modelos lineales, se evidenció la importancia de las condiciones sociales, emocionales y cognitivas como las mejores variables predictoras del nivel de actividad en la muestra estudiada: a) variables emocionales como autoeficacia percibida, emociones positivas, satisfacción con la vida, control personal, adecuadas redes de apoyo; b) características cognitivas como funciones ejecutivas preservadas; c) percepción subjetiva de salud y d) características sociodemográficas como nivel educativo e ingresos. El estudio permite funcionar como línea base, a nivel teórico y metodológico, del envejecimiento con éxito en Costa Rica. Describe los estilos de vida activos en la vejez de los participantes costarricenses, caracterizados primordialmente por la participación en relaciones sociales y ocio, más que por actividades de tipo cognitivas y físicas o vinculadas al logro personal.Palabras clave persona adulta mayor; variables socioemocionales; variables cognitivas; envejecimiento con éxito. ABSTRACTThe present study was aimed at identifying and analyzing the characteristics of older people with high levels of activity and social participation living in Costa Rica, from perspectives like the Successful Aging approach. It also addresses the classical criteria of successful aging theories and their scope in Costa Rican culture. 191 participants between the ages of 55 and 87 (M = 68.5, SD = 6.9) who live in the metropolitan area and participate in programs of the Costa Rican Gerontological Association and the Program for the older people at the University of Costa Rica (in computer courses, languages courses, physical activity, art, among others). Linear models analysis has shown that social, emotional and cognitive factors are the best predictors of the level of activity in
