Social patterning of cardiovascular and metabolic risk in Colombian adults.

OBJECTIVES: To test for differences in cardiovascular and metabolic risk (CMR) by educational attainment and physical capital. To compare CMR among black, indigenous, and mixed populations, accounting for socioeconomic status (SES). DESIGN: We conducted multivariate analyses using cross-sectional data from a national survey of Colombian adults (n = 10,814) to examine the social patterning of CMR. In sex/gender-stratified models, a CMR index was regressed on educational attainment, physical capital, ethnicity/race, and age. RESULTS: Women with a primary education (OR = 1.64, 95% CI: 1.25, 2.15) had higher age- and ethnicity/race-adjusted odds of CMR than women with more than secondary education. Men with a primary education (OR = 0.67, 95% CI: 0.48, 0.92) had significantly lower adjusted odds of CMR than men with more than secondary education; these associations did not remain significant after adjustments for physical capital. Men in the first (OR = 0.45, 95% CI: 0.36, 0.57) and second (OR = 0.72, 95% CI: 0.57, 0.91) physical capital tertiles had significantly lower adjusted odds of CMR than those in the highest tertile. There was not a significant patterning of CMR by ethnicity/race for women or men, or by physical capital for women. CONCLUSIONS: Findings suggest that for Colombian adults CMR is patterned by SES; these associations differ by sex/gender.

Local Actors' Frames of the Role of Living Conditions in Shaping Hypertension Risk and Disparities in a Colombian Municipality.

Conditions in the social and physical environment influence population health and risk for CVD, including hypertension. These environmental conditions are influenced by the decisions of public officials, community leaders, and service providers. Examining the frames that local decision makers bring to understanding hypertension can provide important insights into the decisions that they make about strategies for addressing this problem in their jurisdiction. The goal of this study was to examine the frames that local decision makers in Quibdó, Colombia, bring to understanding hypertension risk, and in particular, whether and how they use frames that encompass associations between living conditions and hypertension risk. Data for this qualitative study were collected using a stratified sampling strategy. Semi-structured interviews were conducted in 2012 with 13 local decision makers and analyzed using a framework approach. Participants linked the structural conditions experienced in Quibdó, including displacement, limited economic opportunities, and the infrastructure of the city, to hypertension risk through multiple pathways, including behavioral risk factors for hypertension and physiologic responses to stress. They described the social patterning of these factors across socioeconomic, racial/ethnic, and gender hierarchies. Although several conditions associated with hypertension risk are widely distributed in the city's population, social processes of marginalization and stratification create additional disadvantages for those on the lower rungs of the social hierarchy.

A prospective longitudinal approach to examine the association between social position in childhood, adolescence, and adulthood with the control of hypertension during adulthood.

Introduction: Hypertension is one of the main concerns in public health, since it is related with increased morbidity, and potential years of life lost in addition to loss of quality of life. This study aimed to assess: (1) the distribution of indicators of life course SEP in a cohort of Colombian patients with hypertension and (2) to assess the association of life course SEP and control of hypertension among this cohort of patients. Methods: Data were obtained using the baseline survey of 258 patients from the Social Determinants and Inequities in the Control of Blood Hypertension Program (ProDSICHA). Mother occupation and housing conditions were measured with the Event History Calendar. Mother educational level was measured with the questionnaire developed by the Project on Ethnicity and Race in Latin America (PERLA). Socioeconomic position during adulthood was measured using education, occupation, and income level based in the MacArthur Network. Results: The group with a higher lifelong social position and the group of lower lifelong social position showed better control of hypertension (OR = 1.21; p <0.05; OR = 1.33; p < .05, respectively) compared to those whose social position throughout life varied the most. No statistical differences were found in the relations between single lifetime social position variables, and hypertension control in the three time points analyzed. Discussion: These findings warrant further research to deeper our understanding on the role of a multidimensional and cumulative approach of social position in hypertension control.

Epidemiological insights into neonatal deaths: The role of cooking fuel pollution in Colombia.

PURPOSE: Household air pollution is one of the leading causes of death and disease globally. Emerging evidence of elevated risk of neonatal death has been reported in Africa and South Asia. However, evidence on the extent of the problem in Latin America is limited despite the persistent use of highly polluting cooking fuels. We assessed whether the use of high-polluting household cooking fuels increases the risk of neonatal death compared to low-polluting fuels in Colombia. METHODS: We used cross-sectional data from the 2005-2015 Colombian Demographic Health Survey and performed a survey-featured multivariate logistic regression. We selected adjustment covariates based on a causal diagram, addressed missing data through multiple imputation, and conducted several sensitivity analysis, such as propensity score matching. RESULT: We found evidence suggesting an increased risk of neonatal death in households using high-polluting fuels (OR: 1.48; 95% CI: 0.91, 2.39). The sensitivity analyses were consistent with the main analysis. CONCLUSION: We observed increased odds of neonatal death associated with using high-polluting household cooking fuels compared to low-polluting fuels, although this association was not statistically significant. This study contributes evidence to a region where the issue is not yet a priority and should be included in national-level discussions and interventions that impact cooking fuel use patterns.

[Socioeconomic status, perception of environment, and their association with self-rated health status among women in Bogotá, Colombia]. / Asociación de la posición socioeconómica y la percepción del ambiente con la autopercepción del estado de salud en mujeres de Bogotá, Colombia.

OBJECTIVE: Evaluate a conceptual model that suggests an association between socioeconomic status (SES), perception of neighborhood environment, physical activity behavior, and self-rated health status (SRHS) among women living in low-resource neighborhoods of Bogotá, Colombia. METHODS: A secondary source analysis of the first measurement of a community cluster trial was used to evaluate a program to encourage a higher consumption of fruits and vegetables and increase physical activity levels among homemakers in Bogotá. Analyses were done using a multivariate multilevel logistic model to identify associations and confirm the mediations proposed in the conceptual model. RESULTS: The adjusted models revealed that individual-level SES and neighborhood perception are inversely and significantly associated with suboptimal SRHS, while the association between physical activity and SRHS was not significant. CONCLUSIONS: The study findings underscore the importance of individual SES in assessment of health status and strengthen the evidence on the independent role of perception of neighborhood environment in the SRHS of women.

Cardiovascular disease prevention capacity in Colombian local health departments.

Prevention capacity of local health organisations is associated with the performance and outcomes in public health. In Colombia, where cardiovascular disease is the leading cause of morbidity and mortality, there is limited knowledge about the capacity of local health departments to prevent this condition. Efforts are needed to address problems, potential solutions and expected outcomes regarding cardiovascular disease. In this study, a conceptual model for cardiovascular disease prevention capacity in Colombian local health departments was developed, a questionnaire based on this model was validated, the overall cardiovascular disease prevention capacity in a subsample of these organisations was measured, and the association between cardiovascular disease prevention capacity and political, population, and organisational factors was examined. Once the acceptable performance of the questionnaire was verified, variability in cardiovascular prevention capacity was found among a subsample of local health departments. Furthermore, this study provides primary evidence regarding the association between the size of local health departments and overall cardiovascular disease prevention capacity in Colombia. Future studies should focus on measuring this capacity on a larger scale and developing, implementing, and evaluating interventions aimed at strengthening cardiovascular prevention capacity in Colombian local jurisdictions.

Using an Intervention Mapping Approach to Develop a Program for Preventing High Blood Pressure in a Marginalized Afro-Colombian Population: A Community-Based Participatory Research.

The prevention of high blood pressure (HBP) is an important public health initiative worldwide, since HBP is the main risk factor for cardiovascular diseases and increases the damage caused by coronavirus disease 2019 (COVID-19). We designed, implemented, and evaluated a program to identify effective and sustainable interventions for preventing HBP in a marginalized black population. Our study was conducted in Quibdó, a city in Colombia with the highest poverty rate and located in the Pacific coast, a subregion in Colombia with the highest prevalence of HBP. We followed an intervention mapping framework using a community-based participatory research approach. Focus groups, photovoice, literature reviews, and cross-sectional quantitative surveys were used for data collection. The community chose the time, place, and type of physical activity; led the physical activities; and strengthened their skills in seeking resources in their community to sustain the program. The evaluation was aimed at determining whether the interventions were able to achieve the program's primary aim. We used a before (September 2016) and after (December 2017) design for the evaluation. To decrease the selection bias and allow comparisons between homogeneous groups, we used a propensity score matching technique. The steps required to create a self-sustaining physical activity program were provided in detail. The pre-post test showed a decrease of the HBP (systolic, 13.4% points; p = 0.018; diastolic, 6.5% points; p = 0.002). The program may be an effective and self-sustaining intervention, and it can be replicated by policymakers and implemented in other population groups.

Built environment interventions and physical activity levels: A systematic review. / Intervenciones en el ambiente construido y niveles de actividad física: una revisión sistemática

INTRODUCTION: Non-communicable diseases are the leading cause of death worldwide and physical activity is a key preventive strategy to reduce them. There is a relationship between the built environment and the practice of physical activity, but little evidence as to whether those built environment interventions not initially designed for promoting physical activity actually have an impact on promoting the behavior. OBJECTIVE: To identify whether such built environment interventions were able to change physical activity in adults. MATERIALS AND METHODS: We conducted a systematic review of interventions targeting modifications to the built environment changes in urban areas. RESULTS: Out of 5,605 articles reviewed, only seven met our inclusion criteria. The seven studies found higher levels of physical activity after the interventions. CONCLUSIONS: We recommend greater specificity regarding the study design, the timeline of interventions implementation and post-intervention measurements, as well as the use of more objective measures. Finally, we point out the need to make more explicit the mechanisms of change related to the interventions assessed.

Introducción. Las enfermedades no transmisibles son la principal causa de muerte en todo el mundo y la actividad física es una estrategia preventiva clave para reducirlas. Hay una relación entre el entorno construido y la práctica de actividad física, pero poca evidencia de si las intervenciones no diseñadas en principio para promoverla, realmente tienen un impacto en ese sentido. Objetivo. Determinar si tales intervenciones en el entorno urbano pudieron cambiar la práctica de actividad física en adultos. Materiales y métodos. Se hizo una revisión sistemática de las intervenciones que apuntaban a modificar el entorno construido en zonas urbanas. Resultados. De 5.605 artículos considerados, solo siete cumplieron con nuestros criterios de inclusión y en todos ellos aumentó la actividad física después de la intervención. Conclusiones. Se recomienda que el diseño del estudio, el cronograma de implementación de las intervenciones y las mediciones posteriores sean más específicas, de manera que las medidas obtenidas sean más objetivas. Asimismo, se argumenta la necesidad de hacer más explícitos los mecanismos de cambio relacionados con las intervenciones evaluadas.

Using participatory action research to reimagine community mental health services in Colombia: a mixed-method study protocol.

INTRODUCTION: Mental healthcare systems are challenged by how they hear and respond to what marginalised communities experience as drivers of mental distress. In Colombia, this challenge intersects with wider challenges facing post-conflict reconstruction. Our pilot study will explore the feasibility and acceptability of a participatory approach to developing community-led participatory interventions for community mental health systems strengthening and mental health improvement, in two sites in Caquetá, Colombia. METHODS AND ANALYSIS: The project is divided into three distinct phases aligned with community participatory action research cycles: diagnostic, intervention and evaluation. This allows us to use a participatory approach to design a community-led, bottom-up intervention for mental health systems strengthening and the promotion of mental health and well-being.The diagnostic phase explores local understandings of mental health, mental distress and access to mental health services from community members and health providers. The intervention stage will be guided by a participatory Theory of Change process. Community priorities will inform the development of a participatory, learning and action (PLA) informed group intervention, with a community linkage forum. The pilot of the PLA intervention will be evaluated using MRC process evaluation guidelines. ETHICS AND DISSEMINATION: This project has received ethical approval from two sources. Universidad de Los Andes (2021-1393) and the University College London (16127/005). Dissemination of findings will include academic publications, community forums, policy briefs and visual media (cartoons, pod casts and short films).

Association of Leisure Activities With Cognitive Impairment and Dementia in Older Adults in Colombia: A SABE-Based Study.

Observational and interventional studies suggest that participation in leisure activities may help protect against cognitive decline in older people. This study aimed to examine the association between participation in leisure activities and cognitive impairment in older adults in Colombia. Data for this study were derived from the Colombian National Survey of Aging (SABE 2015), a cross-sectional survey with a sample size of 23,694 older adults representing the total population (mean age, 70.8 years; 57.3% females). Cognitive impairment was classified as cognitive impairment without dementia (CIWD) and dementia, according to the revised version of the Folstein Mini-Mental State Examination and the Lawton and Brody functional scale. Leisure activities were evaluated using six items of a questionnaire. Sex-stratified multinomial regression models were used to analyze the association of leisure activities with CIWD and dementia after adjusting for educational attainment, literacy, and other potential confounders. In adjusted models for men, leisure activities in later life were associated with a decreased risk of CIWD (odds ratio [OR], 0.73; 95% confidence interval [CI], 0.68-0.78) and dementia (OR, 0,52; 95% CI, 0.48-0.58). For women, leisure activities in later life were associated with a decreased risk of CIWD (OR, 0.72; 95% CI, 0.66-0.78) and dementia (OR, 0.48; 95% CI, 0.43-0.53). The findings suggest that greater participation in leisure activities in later life may act as a protective factor against CIWD and dementia among older adults in Colombia, independent of educational attainment and literacy.

Socioeconomic position and quality of life among Colombian hypertensive patients: The mediating effect of perceived stress.

This study aimed to assess the relationships between socioeconomic position, perceived stress and Health Related Quality of Life (HRQoL) of patients with hypertension. Data were obtained using the baseline survey of 258 patients from the Social Determinants and Inequities in the Control of Blood Hypertension Program (ProDSICHA). HRQoL was measured with SF-8 Health Survey. Socioeconomic position was measured using education, and the MacArthur Scale. Stress was measured with Perceived Stress Scale. A higher educational level was associated with a higher perception of stress (Coeff = 0.78, p = 0.019). Also, a lower position in the community was associated with a higher perception of stress (Coeff = -0.56, p = 0.027). A higher level of perceived stress was associated with a higher level of mental health (Coeff = 0.64, p = 0.000). No statistical differences were found in the relations between socioeconomic position and physical HRQoL. These findings warrant further research to understand the role of socioeconomic position in physical HRQoL.

Association of education level with diabetes prevalence in Latin American cities and its modification by city social environment.

BACKGROUND: Diabetes prevalence continues to increase in urban areas of low-income and middle-income countries (LMIC). Evidence from high-income countries suggests an inverse association between educational attainment and diabetes, but research in LMIC is limited. We investigated educational differences in diabetes prevalence across 232 Latin American (LA) cities, and the extent to which these inequities vary across countries/cities and are modified by city socioeconomic factors. METHODS: Using harmonised health survey and census data for 110 498 city dwellers from eight LA countries, we estimated the association between education and diabetes. We considered effect modification by city Social Environment Index (SEI) as a proxy for city-level development using multilevel models, considering heterogeneity by sex and country. RESULTS: In women, there was an inverse dose-response relationship between education and diabetes (OR: 0.80 per level increase in education, 95% CI 0.75 to 0.85), consistent across countries and not modified by SEI. In men, Argentina, Brazil, Colombia, Chile and Mexico showed an inverse association (pooled OR: 0.92; 95% CI 0.86 to 0.99). Peru, Panama and El Salvador showed a positive relationship (pooled OR 1.24; 95% CI 1.04 to 1.49). For men, these associations were further modified by city-SEI: in countries with an inverse association, it became stronger as city-SEI increased. In countries where the association was positive, it became weaker as city-SEI increased. CONCLUSION: Social inequities in diabetes inequalities increase as cities develop. To achieve non-communicable disease-related sustainable development goals in LMIC, there is an urgent need to develop policies aimed at reducing these educational inequities.

Do the determinants of self-rated health vary among older people with disability, chronic diseases or both conditions in urban Colombia?

Our study aimed to identify the main determinants of self-rated health for individuals aged 60 years or older in Bogotá, Colombia, and if those determinants vary between groups. Data was obtained from the Demographic Health Survey 2011 for Bogotá. Logistic regression models were estimated to identify the determinants of excellent/good self-rated health among people aged 60 years or older living in Bogotá. Moreover, a subgroup analysis was conducted seeking to identify if the determinants changed between groups (men, women, persons with disability, with chronic disease(s), and persons with both disability and chronic disease(s)). The likelihood of reporting an excellent/good self-rated health health decreases when the individual has a disability, a chronic disease or reports that their household income is not enough to cover the basic needs. On the other hand, the odds of reporting excellent/good self-rated health increase when the individual is more educated and reports to receive family support. The subgroup analysis showed that although some determinants are only associated with one group (age with chronic diseases), in general, three main determinants stood out: years of education, socioeconomic status variables and receiving family support. The determinants of self-rated health for older adults in Bogotá differ according to the disability and the chronic disease status. Thus, public policies aiming to improve the levels of health and quality must consider the impacts of those characteristics on individuals' perceptions of their own health.

Establishing a local coalition for addressing social determinants of hypertension in Quibdó (Colombia): a description and reflection on the process.

One-fourth of the adult population of Colombia is estimated to have hypertension. However, there has been relatively little attention to participatory approaches that address the social determinants of hypertension at the local level in Colombia. Early stages of a coalition for addressing hypertension in Quibdó (Colombia) included a stakeholder analysis and engagement of local organizations. This was followed by defining mutual goals, agreement of rules for decision making, and refining a shared vision. Based on a unified understanding of factors influencing hypertension risk, 12 organizations joined the local coalition. They developed an action plan for preventing hypertension and eliminating social disparities in its distribution. Lessons learned during this process suggest that, in marginalized urban areas of middle- and low-income countries, particular attention should be paid, at early implementation stages of coalition, to context specific challenges and opportunities, coalition membership and structure, reframing health, and strengthening capacity.

Chronic stress as a mediator of the relationship between socioeconomic status and pharmacological adherence in hypertensive patients / [El estrés crónico como mediador de la relación entre la posición socioeconómica y el cumplimiento del tratamiento farmacológico de pacientes hipertensos].

Introduction: High blood pressure is a public health problem worldwide. In Colombia, its prevalence is 25% with a high mortality rate. The psychosocial factors affecting pharmacological adherence among patients have not been sufficiently studied and despite international evidence on their impact, in Colombia, there is a paucity of research on the role of chronic stress in the relationship between socioeconomic status and pharmacological adherence. Objective: To examine the role of chronic stress in the relationship between socioeconomic status and pharmacological adherence in hypertensive patients aged 45 to 70 years old in three Colombian cities between 2015 and 2016. Materials and methods: We conducted a cross-sectional study in a population of hypertensive patients. Data for this study came from the first wave of longitudinal study aimed at examining social factors associated with the control of hypertension in Bogotá, Medellín, and Quibdó. Patients with hypertension were selected randomly from a sample of those participating in the hypertension control program De todo corazón. For the statistical analysis of the data, we used factorial analysis and multivariate regressions. Results: We found a positive association between socioeconomic status and the degree of pharmacological adherence and a negative one with chronic stress. Besides, evidence was found that stress has a negative association with the degree of adherence. Conclusions: The results suggest that stress is not a likely mediator between socioeconomic status and the pharmacological adherence of hypertensive patients in Colombia. Additional studies are required to confirm these relationships with a larger sample.

Introducción. La hipertensión arterial sistémica es un problema de salud pública en el mundo. En Colombia, su prevalencia es del 25 % y la mortalidad es alta. Los factores psicosociales que afectan el cumplimiento del tratamiento farmacológico no han sido estudiados suficientemente. En otros países, se ha estudiado el papel del estrés crónico en la relación entre la posición socioeconómica y el cumplimiento del tratamiento farmacológico antihipertensivo. Objetivo. Examinar el papel del estrés crónico como mediador de la relación entre la posición socioeconómica y el cumplimiento del tratamiento farmacológico, en pacientes hipertensos de 45 a 70 años en el 2015 y el 2016. Materiales y métodos. Se hizo un estudio transversal de una población de pacientes hipertensos. Los datos provienen de la muestra seleccionada para el programa "De todo corazón" en Bogotá, Medellín y Quibdó. El análisis estadístico de los datos se hizo mediante análisis factorial y regresiones multivariadas. Resultados. Los resultados confirmaron una asociación positiva entre la posición socioeconómica y el grado de cumplimiento del tratamiento farmacológico, y una relación negativa entre la primera y el estrés crónico. Además, se evidenció que el estrés tiene una asociación negativa con el grado de cumplimiento. Conclusiones. Los resultados sugieren que el estrés no es un mediador entre la posición socioeconómica y el cumplimiento del tratamiento farmacológico antihipertensivo en Colombia. Se requieren estudios adicionales para confirmar estas relaciones con una muestra más amplia.

[Possible public health implications regarding associations between the degree of urbanisation and electronic media exposure amongst Colombian children]. / Niveles de urbanización, uso de televisión y video-juegos en niños Colombianos: posibles implicaciones en salud pública.

OBJECTIVE: Determining the association between the degree of urbanisation and excessive television-viewing and video-game use amongst children aged 5 to 12 years old. METHODS: Data from the Colombian National Nutritional Survey 2005 was used in the analysis. Television viewing and video-game use was determined through parental reports for 13,090 children and classified as being excessive (e' 2 hours/day) or suitable (<2 hours/day). Five levels of urbanisation were determined using criteria from the National Planning Department and the population size of the rural or urban settings included in the survey. Multiple logistical regression analysis was conducted while taking potential confounders into account. RESULTS: There was a gradual increase in the probability of TV or videogames being used for 2 hours or more as the degree of urbanisation increased. This association was statistically significant for urbanisation level 3 and higher (urbanisation level 2, OR=1,33: 0,89-1,99 95 %CI; urbanisation level 3, 1,35=OR: 1,00-1,80 95 %CI; urbanisation level 4, 1,61=OR: 1,16-2,23 95 %CI and urbanisation level 5, 1,7=OR: 1,17-2,46 95 %CI). CONCLUSION: Colombian children living in areas of high-to-moderate urbanisation and population density are at a higher risk of excessive exposure to electronic media entertainment. Due to its multiple health implications (in particular obesity and cardio-metabolic health), such sedentary behaviour should be monitored and its determinants in the Colombian paediatric population must be understand for making effective public health interventions.

[Local planning to tackle the threat of the chronic diseases in Pasto, Colombia]. / Planeación Local para enfrentar el Desafío de las Enfermedades Crónicas en Pasto, Colombia.

Chronic diseases are increasing problem of public health in the world. In countries such as Colombia these diseases are an important cause of morbidity and mortality. Taking into account this situation several organizations have recommended planning and conducting actions to prevent chronic diseases, however there are scarce initiatives addressed to this purpose which reflect a reality that has been named as the "neglected epidemic of chronic diseases". This article describes the experience of formulation of a local plan for the prevention of chronic diseases in the Colombian city of Pasto where was used a planning model developed by the World Health Organization. The goal of this plan is reduce in the following ten year the prevalence of the three main risk factors for chronic disease between 5 to 10% addressing the actions in public policies, contexts for the daily life, health services and the generation of evidence to make decisions through an observatory in chronic diseases. This experience showed up the importance and feasibility of this process at the local context and identified the coordination with the national level as one of the main challenges to be considered to carry out these initiatives.

Television viewing and its association with overweight in Colombian children: results from the 2005 National Nutrition Survey: a cross sectional study.

BACKGROUND: There has been an ongoing discussion about the relationship between time spent watching television and childhood obesity. This debate has special relevance in the Latin American region were the globalization process has increased the availability of screen-based entertainment at home. The aim of this study is to examine the association between television viewing and weight status in Colombian children. METHODS: This cross sectional investigation included children aged 5 to12 yrs from the National Nutrition Survey in Colombia (ENSIN 2005). Weight and height were measured in 11,137 children in order to calculate body mass index. Overweight was defined by international standards. Time spent viewing television was determined for these children through parental reports. Multiple logistic regression analyses were conducted for different subgroups and adjusted for potential confounders in order to study the association between television viewing and weight status in this population. RESULTS: Among the surveyed children, 41.5% viewed television less than two hours/day; 36.8% between two and 3.9 hours/day and 21.7% four or more hours/day. The prevalence of overweight (obesity inclusive) in this population was 11.1%. Children who were classified as excessive television viewers (between two and 3.9 hours/day or 4 or more hours/day) were more likely to be overweight (OR: 1.44 95% CI: 1.41-1.47 and OR: 1.32 95% CI: 1.30-1.34, respectively) than children who reported to watch television less than 2 hours/day. Stratified analyses by age, gender and urbanization levels showed similar results. CONCLUSION: Television viewing was positively associated with the presence of overweight in Colombian children. A positive association between urbanization level and television viewing was detected. Considering that the majority of Colombian children lives in densely populated cities and appear to engage in excessive television viewing these findings are of public health relevance for the prevention of childhood obesity.
