Introduction: Colombian population is getting old in an accelerated manner, causing economic, social and health services effects. The Ministry of Health and Social Protection in the National System of Population Studies and Surveys for Health implemented the first health, well-being and aging survey- SABE-2015 Colombia- to know the living conditions of people 60 years of age or older. Objective: Describe the design of the method, statistical sampling and quality control of information from the SABE-2015 survey. Methods: A cross-sectional study, with quantitative and qualitative approaches, representative for the population in urban and rural areas aged 60 or over. Information was collected on socioeconomic variables, physical and social environment, behavior, cognition and affection, functionality, mental well-being, health conditions, and the use and access to health services. Results: 23,694 surveys were conducted, 17,189 in urban population (72.5%) and 6,505 in rural population. The percentage of effective national response was 66% in 244 municipalities. Supervision was made in 40% of the surveys and telephone re-contact in 25%. The consistency of 100% surveys was reviewed and double entry was developed in 5% of them. National estimates have a 5% margin error. Conclusion: The SABE Colombia 2015 survey is representative of the main indicators of health, well-being and aging in Colombia. The design allows regional comparisons, between large cities and urban and rural population.

Dengue is a vector-borne disease that has increased over the past two decades, becoming a global public health emergency. The transmission of dengue is contingent upon various factors, among which climate variability plays a significant role. However, there remains substantial uncertainty regarding the underlying mechanisms. This study aims to investigate the spatial and temporal patterns of dengue risk and to quantify the associated risk factors in Valle del Cauca, Colombia, from 2001 to 2019. To achieve this, a spatio-temporal Bayesian hierarchical model was developed, integrating delayed and non-linear effects of climate variables, socio-economic factors, along with spatio-temporal random effects to account for unexplained variability. The results indicate that average temperature is positively associated with dengue risk 0-2 months later, showing a 35% increase in the risk. Similarly, high precipitation levels lead to increased risk approximately 2-3 months later, while relative humidity showed a constant risk within a 6 months-lag. These findings could be valuable for local health authorities interested in developing early warning systems to predict future risks in advance.

Introduction: High blood pressure (HBP) is the main cardiovascular risk factor, it is more prevalent in the older adult population, and the prevalence can vary between ethnic groups. Objective: To estimate the prevalence of HBP, knowledge, treatment and control in population aged ≥60 years, resident in Colombia, according to their ethnic condition. Methods: Population sample selected by multistage sampling. Ethnicity was defined based on skin color. HBP was defined as systolic blood pressure ≥140, and/or diastolic blood pressure ≥90 mm Hg, and/or the participants’ self-report. Controlled HBP at a blood pressure value <140/90, knowledge and treatment were identified by self-report. Results: 23,694 adults aged ≥ 60 years were included, of which 54.5%, 34.5% and 10.9% were respectively identified as having light, medium or dark skin color; 54.5% were women, and 78.1% resided in urban areas. The standardized prevalence of HBP, by age, was 57.7% (95% CI: 55.2 - 60.2); 51.4% (95% CI: 47.3-55. 5), in men; and 62.9% (60.964.9), in women. The standardized prevalence for light, medium and dark skin in men was 53.2% (95% CI: 48.7-57.7), 49.6% (44.5-54.7), and 49.4% (95% CI: 41.0-57.8) respectively; and in women was 62.5% (95% CI: 60.5-64 , 5), 61.7% (95% CI: 57.865.6), and 69.9% (95% CI: 63.6-76.2) respectively. 98% of the population received treatment, and 93.9% were aware of HBP diagnosis. 42.5% of men and 55.5% of women with HBP were under control. Only 21.8% performed regular physical activity. Conclusion: Half of the adult population aged over 60 years suffers from HBP; the prevalence is higher in women particularly in dark-skinned women. It is necessary to develop policies to increase physical activity in the elderly.

Objetivo Describir la distribución espacio-temporal del COVID-19 en la ciudad de Cali durante el primer mes de epidemia.Métodos Se realizó un análisis exploratorio de datos espaciales, compuesto por un análisis de densidad de Kernel y se verificó la presencia de patrones espaciales por medio de la función K de Ripley.Resultados La distribución espacial de los casos tiende a concentrarse inicialmente en el norte y sur de la ciudad, con una dinámica cambiante hacia el oriente y occidente.Conclusiones El patrón espacial identificado puede estar influenciado por las medidas de aislamiento tomadas a nivel local y nivel nacional, además no se puede descartar el efecto del poco acceso que tiene la población general a las pruebas diagnósticas,los retrasos y represamientos para conocer los resultados de las mismas y aun los posibles sesgos por dificultades en la técnica de toma de la muestra o su conservación.

Our study is based on the Colombia SABE survey (Health, Well-Being, and Aging Study), which included 23,694 individuals aged 60+ in urban and rural areas of the country. The analysis addresses adult self-perception of health status as a dependent variable and its relationships to ethnic/racial self-recognition and to interviewer-ascribed skin color as a phenotypic trait using a validated technique with a color palette. Social inequalities were determined based on the characterization of socioeconomic status, urban or rural residence, literacy, and the average years of education attained. Our study brought together socioeconomic factors, ethnic-racial self-recognition and skin color as factors of discrimination. Descriptive statistical tests and four adjusted logistic models were developed, controlling by the sex and the age of the individuals. The findings show that adults in households with better socioeconomic conditions have a better self-perception of health. Regarding ethnic-racial self-recognition, Afro-descendant, black, and mulatto adults have less good health perception than white-mestizo adults and face the worst socioeconomic conditions. In summary, skin color and ethnic and racial self-recognition categories, together with classic socioeconomic variables, are relevant to understand the health status self-perception of older adults as part of the processes of exclusion and discrimination that have consequences for health inequalities.
