Self-reported vaccination in the elderly: SABE study Bogotá, Colombia

Abstract

Objective: To assess the self-reported vaccination in older adults within the city of Bogotá and its distribution by sociodemographic factors. Methods: Data analyzed was taken from the SABE-Bogotá study. A total of 2000 persons aged 60 years and older were selected for this cross-sectional population-based study. Bivariate and multivariate analyses were performed testing the association between vaccination and sociodemographic factors. Results: A total of 73.0% of respondents received the influenza vaccine, 57.8% received pneumococcal vaccine and 47.6% received tetanus vaccine. In multivariate analyses, individuals aged between 65-74 years had higher odds of receiving influenza, pneumococcus and tetanus vaccination, compared to those between 60-64 years. Older adults with higher socioeconomic status (SES) had lower odds of having influenza and pneumococcus vaccines, compared to those with lower SES (OR= 0.16 95% confidence intervals= CI 0.08-0.30; OR 0.20 95% CI 0.10-0.38, respectively). Individuals covered by health insurance (contributive or subsidized) had higher odds (between 3 and 5 times higher) of having influenza, pneumococcus and tetanus vaccination, compared to those with no insurance. Conclusion: Older adults between 65 and 74 years, those with health care coverage and people with low SES are groups that have increased odds for self-reported vaccination. Further studies should identify factors that increase vaccination coverage in these groups and implement interventions targeted at improving coverage among older adults in general.

Trends, Coverage and Influencing Determinants of Influenza Vaccination in the Elderly: A Population-Based National Survey in Spain (2006–2017)

“…In the univariate analysis, older people from social Classes V and VI had a higher influenza vaccination coverage than those from higher classes. This situation is similar to that found in some studies [12,65,66] and may be due to people from higher social classes possibly being more susceptible to both anti-vaccination campaigns and the increased perception of the potential risks of vaccinations [65].…”

Analysis of influenza vaccination coverage among the elderly living in Rome, based on a deprivation index, 2009-13

“…Indeed, most studies conducted in elderly populations across different seasons and countries have reported higher influenza vaccination uptake in low deprivation groups [ 14 , 15 , 28 ]. Only two studies, conducted in Colombia [ 29 ] and Germany [ 30 ], had findings similar to ours, and reported that elderly people from higher social classes had lower influenza vaccination coverage than those from lower and middle classes. We hypothesize that our findings might be the consequence of anti-vaccination campaigns [ 31 ], which have grown in Italy, and of the increased perception of the potential risks of vaccination [ 32 ], as people from higher socioeconomic classes may be more susceptible to both influences.…”

Another possible explanation is that, in the high deprivation groups, people with chronic and/or co-morbid conditions are more likely to visit health-care facilities and have vaccination advised and given [ 29 ].…”

Education and pneumonia mortality: a trend analysis of its inequalities in Colombian adults

“…The results reported coverage for vaccination among individuals of 60 years and older is 73.0% for influenza, 57.8% for pneumococcus and 47.6% for tetanus. 62 However, these coverages are surely lesser in other Colombian territories. There is enough evidence regarding the association between educational status and vaccination.…”
