Objective:
To identify the relationship between religiosity and self-rated health among older adults in Colombia.
Methods:
Data are drawn from the SABE (Salud, Bienestar y Envejecimiento) Colombia Study, a
cross-sectional survey conducted in 2015 involving 18,871 community-dwelling adults
aged 60 years and older living in urban and rural areas of Colombia. Religiosity was
assessed by self-rated religiosity (how religious are you: not at all, somewhat or very).
Self-rated health during previous 30 days was assessed as very good, good, fair, poor
or very poor, analyzed as an ordinal variable(1-5) using weighted logistic regression,
adjusting for confounders.
Results:
Those who were more religious were older, female, had lower socioeconomic status,
and were more likely to be married. Multivariate analyses demonstrated that older
adults who were more religious had better self-rated health (OR 0.92 95% CI 0.86-
0.99, p= 0.038); however, there was a significant interaction effect between gender
and religiosity on self-rated health (p= 0.002), such that the relationship between
religiosity and health was stronger in men (OR 0.86, 95% CI: 0.79-0.94, p= 0.001) but
not significant in women.
Conclusion:
Older adults in Colombia who consider themselves more religious, especially men, are
less likely to perceive their physical health as poor compared to those who are less
religious.
La obesidad es una enfermedad multifactorial, es decir que resulta de la interacción de múltiples factores genéticos y ambientales. Para su estudio se hace necesario el uso de herramientas de investigación que permitan explorar mecanismos de interacción entre el genoma completo y la nutrición. La genómica nutricional que engloba la nutrigenética y la nutrigenómica ha estudiado el papel de los genes en la obesidad. Aunque estas dos últimas están íntimamente asociadas, toman un enfoque diferente para entender la relación entre los genes y la dieta. Se han encontrado diversas variantes genéticas asociadas a la susceptibilidad de la enfermedad, con el Índice de Masa Corporal, el porcentaje de grasa corporal, la circunferencia de la cintura y la relación cintura cadera, así como la interacción entre estas y el consumo de diferentes nutrientes como los hidratos de carbono y los lípidos. Se ha postulado que varias regiones del genoma están asociadas al control del peso corporal, y la forma como ciertos nutrientes pueden incluso modificar algunos procesos celulares que aumentan el riesgo de obesidad. Aún cuando estos hallazgos son de valioso significado, presentan limitaciones que impiden que hasta el momento tengan aplicación clínica. El objetivo de esta revisión es describir los avances en la genómica nutricional respecto a la obesidad y cuál ha sido el papel y la aplicación de las ciencias ómicas en su estudio.
