Urban social determinants of non-communicable diseases risk factors in Argentina

The burden of premature coronary heart disease among adults with low socioeconomic status in Argentina: A modeling study

BACKGROUND

The well-established inverse relationship between socioeconomic status (SES) and risk of developing coronary heart disease (CHD) cannot be explained solely by differences in traditional risk factors.

OBJECTIVE

To model the role SES plays in the burden of premature CHD in Argentina.

MATERIALS AND METHODS

We used the Cardiovascular Disease Policy Model-Argentina to project incident CHD events and mortality in low and high-SES Argentinean adults 35 to 64 years of age from 2015 to 2024. Using data from the 2018 National Risk Factor Survey, we defined low SES as not finishing high-school and/or reporting a household income in quintiles 1 or 2. We designed simulations to apportion CHD outcomes in low SES adults to: (1) differences in the prevalence of traditional risk factors between low and high SES adults; (2) nontraditional risk associated with low SES status; (3) preventable events if risk factors were improved to ideal levels; and (4) underlying age- and sex-based risk.

RESULTS

56% of Argentina´s 35- to 64-year-old population has low SES. Both high and low SES groups have poor control of traditional risk factors. Compared with high SES population, low SES population had nearly 2-fold higher rates of incident CHD and CHD deaths per 10 000 person-years (incident CHD: men 80.8 [95%CI 76.6-84.9] vs 42.9 [95%CI 37.4-48.1], women 39.0 [95%CI 36.-41.2] vs 18.6 [95%CI 16.3-20.9]; CHD deaths: men 10.0 [95%CI 9.5-10.5] vs 6.0 [95%CI 5.6-6.4], women 3.2 [95%CI 3.0-3.4] vs 1.8 [95%CI 1.7-1.9]). Nontraditional low SES risk accounts for 73.5% and 70.4% of the event rate gap between SES levels for incident CHD and CHD mortality rates, respectively.

DISCUSSION

CHD prevention policies in Argentina should address contextual aspects linked to SES, such as access to education or healthcare, and should also aim to implement known clinical strategies to achieve better control of CHD risk factors in all socioeconomic levels.

Spatial characteristics of non-communicable diseases and their associations to social conditions in a large urban cohort in Germany-Results from the Hamburg City Health Study

BACKGROUND

Non-communicable diseases (NCDs) are responsible for many deaths. They are associated with several modifiable and metabolic risk factors and are therefore prone to significant regional variations on different scales. However, only few intra-urban studies examined spatial variation in NCDs and its association with social circumstances, especially in Germany. Thus, the present study aimed to identify associations of personal risk factors and local social conditions with NCDs in a large German city.

METHODS

This study is based on a population-based cohort of the Hamburg City Health Study including 10,000 probands. Six NCDs were analyzed (chronic obstructive pulmonary disease [COPD], coronary heart disease [CHD], diabetes mellitus, heart failure, depression, and hypertension) in 68 city district clusters. As risk factors, we considered socio-demographic variables (age, sex, education) and risk behaviour variables (smoking, alcohol consumption). Logistic regression analyses identified associations between the district clusters and the prevalence rates for each NCD. Regional variation was detected by Gini coefficients and spatial cluster analyses. Local social condition indexes were correlated with prevalence rates of NCDs on city district level and hot-spot analyses were performed for significant high or low values.

RESULTS

The analyses included 7,308 participants with a mean age of 63.1 years (51.5% female). The prevalence of hypertension (67.6%) was the highest. Risk factor associations were identified between smoking, alcohol consumption and education and the prevalence of NCDs (hypertension, diabetes, and COPD). Significant regional variations were detected and persisted after adjusting for personal risk factors. Correlations for prevalence rates with the local social conditions were significant for hypertension (r = 0.294, p < 0.02), diabetes (r = 0.259, p = 0.03), and COPD (r = 0.360, p < 0.01).

CONCLUSIONS

The study shows that regional differences in NCD prevalence persist even after adjusting for personal risk factors. This highlights the central role of both personal socio-economic status and behaviors such as alcohol and tobacco consumption. It also highlights the importance of other potential regional factors (e.g. the environment) in shaping NCD prevalence. This knowledge helps policy- and decision-makers to develop intervention strategies.

Gender differences in trajectories of health-related quality of life from childhood to adolescence in a 7-year follow-up study in a urban socially disadvantaged sample from Argentina

PURPOSE

The transition from childhood to adolescence is a period of developmental changes, with social influences. Few previous studies have analyzed changes in health-related quality of life (HRQoL) during childhood and adolescence based on longitudinal studies in high-income countries. This study aimed to describe the evolution of HRQoL scores by gender in a school sample over a 7-year period in Argentina.

METHODS

Prospective cohort of children attending fourth grade in public schools. HRQoL was measured using the KIDSCREEN-52 questionnaire. Trajectories of HRQoL were estimated for girls and boys through multilevel models, adjusted by socioeconomic status (SES).

RESULTS

The study began in 2014 with a sample of 494 school children, reaching an 85.6% response rate in 2016, 31.4% in 2018, and 41.9% in 2021. Most of the predicted scores are negatively associated with linear age or/and quadratic age, suggesting a decrease in scores over the 7-year follow-up. Interactions between gender and age denote an increase in the differences in scores between girls and boys over time in favor of the latter. For the Index, Physical Well-being, Psychological Well-being, Autonomy, Parent relations, Social support and peers and Financial resources, individuals with medium or high SES have significantly higher scores than those with low SES.

CONCLUSIONS

HRQoL scores decrease during the transition period from childhood to adolescence, with girls showing the greatest decrease. There were also socioeconomic inequalities in the evolution of HRQoL in a context characterized by social segregation and economic crisis, possibly aggravated by the COVID-19 pandemic.

Gender differences in the association of individual and contextual socioeconomic status with hypertension in 230 Latin American cities from the SALURBAL study: a multilevel analysis

BACKGROUND

Despite global interest in gender disparities and social determinants of hypertension, research in urban areas and regions with a high prevalence of hypertension, such as Latin America, is very limited. The objective of this study was to examine associations of individual- and area-level socioeconomic status with hypertension in adults living in 230 cities in eight Latin America countries.

METHODS

In this cross-sectional study, we used harmonized data from 109,184 adults (aged 18-97 years) from the SALURBAL (Salud Urbana en America Latina/Urban Health in Latin America) project. Hypertension was assessed by self-report. Individual-, sub-city- and city-level education were used as proxies of socioeconomic status. All models were stratified by gender.

RESULTS

Higher individual-level education was associated with lower odds of hypertension among women (university education or higher versus lower than primary: odds ratio [OR] = 0.67, 95% confidence interval [CI] = 0.61-0.74) but higher odds among men (OR = 1.65; 95%CI 1.47-1.86), although in men an inverse association emerged when measured blood pressure was used (OR = 0.86; 95%CI 0.76-0.97). For both genders, living in sub-city areas with higher educational achievement was associated with higher odds of hypertension (OR per standard deviation [SD] = 1.07, 95%CI = 1.02-1.12; OR = 1.11 per SD, 95%CI = 1.05-1.18, for women and men, respectively). The association of city-level education with hypertension varied across countries. In Peru, there was an inverse association (higher city level education was associated with lower odds of hypertension) in women and men, but in other countries no association was observed. In addition, the inverse association of individual-level education with hypertension became stronger (in women) or emerged (in men) as city or sub-city education increased.

CONCLUSION

The social patterning of hypertension differs by gender and by the level of analysis highlighting the importance of context- and gender-sensitive approaches and policies to reduce the prevalence of hypertension in Latin America.

Process of developing the National Health in All Policies Framework to address social determinants of health in Tanzania Mainland: lessons learned, 2018 - 2022

Introduction

social determinants of health (SDH) are the non-medical factors that contribute to various infectious and non-infectious diseases in Tanzania. Studies suggest that SDH account for 30-55% of health outcomes globally. Most SDH are outside the mandate of the health sector; hence, multi-sectoral collaboration through Health in All Policies (HiAP) is critical. Health in All Policies looks at public policies across sectors that consider health implications of decisions, seek synergies, use resources and avoid harmful health impacts to improve population health and health equity. This paper demonstrates lessons learned from the process of developing National HiAP Framework in Tanzania Mainland to address SDH. It is expected that countries will be able to learn and adopt what deems fit in their context as they address SDH to improve population health.

Methods

different methods were used to promote multi-sectoral collaboration in addressing SDH through HiAP. They included consultations with Prime Minister's Office (PMO) as the coordinator of Government business for their buy-in. High-level advocacy meetings of Directors of Policy and Planning and Permanent Secretaries from sectoral ministries were conducted to move forward the HiAP agenda. Capacity building was provided for sectoral Ministries to understand HiAP concept and SDH. Interministerial collaboration meetings were convened to bring sectors together to identify SDH issues and key areas for inter-sectoral collaboration and develop National HiAP Framework to address SDH. Health in All Policies Secretariat coordinates the HiAP activities.

Results

it has been noted that almost every sectoral ministry has a health component in its policy which contributes to the Tanzanian population's health. In this regard, every sectoral ministry has a role to play in addressing SDH for sustainable development. Political will is key in moving forward the HiAP agenda. The role of PMO is significant to ensure inter-sectoral collaboration. Achieving the national and Sustainable Development Goals require strong collaboration among sectors and stakeholder coordination at all levels through HiAP.

Conclusion

implementing HiAP is a win-win situation. It enhances inter-sectoral collaboration, benefiting each sector to achieve its health-related strategic indicators and ultimately achieve national and global goals.

Utilizing Go-Yoga Smartphone Application to Prevent Preeclampsia in Pregnant Women

After bleeding, hypertension is the second leading cause of maternal death.  Hypertension is caused by a combination of factors, including increased stress and a low level of albumin. All of these changes will cause complications and necessitate long-term medication therapy. As a result, complementary therapies such as family roles and yoga are required. Many people are unfamiliar with yoga movements, so this study provides innovation by incorporating yoga into a smartphone application. The objective of the study is to determine the differences in the implementation of the Go-Yoga smartphone application and the role of the family in pregnant women in the III trimester on blood pressure and albumin levels. This type of research is quasi-experimental involving 60 pregnant women in the third trimester. In Group I, 20 pregnant women practiced yoga with books; in Group II, 20 pregnant women exercised yoga with the Go-Yoga app without their families; and in Group III, 20 pregnant women practiced yoga with their families. The study's results revealed significant blood pressure, with the third group having the highest average (p = 0.000 1). Pregnant women who utilize the Go-Yoga app with their families have lower blood pressure than other groups. Furthermore, pregnant women who employ the Go-Yoga app with their families have higher albumin levels than other groups. Therefore, this study suggests employing the Go-Yoga application with the family prevents hypertension in pregnancy.

Are Women's Empowerment and Income Inequality Associated with Excess Weight in Latin American Cities?

While income gradients and gender inequalities in excess weight have been noted elsewhere, data from Latin American cities is lacking. We analyzed gender-specific associations between city-level women's empowerment and income inequality with individual-level overweight/obesity, assessing how these associations vary by individual education or living conditions within cities in Latin America. Data came from national surveys and censuses, and was compiled by the SALURBAL project (Urban Health in Latin America). The sample included 79,422 individuals (58.0% women), living in 538 sub-cities, 187 cities, and 8 countries. We used gender-stratified Poisson multilevel models to estimate the Prevalence Rate Ratios (PRR) for overweight/obesity (body mass index ≥ 25 kg/m²) per a unit change in city-level women's empowerment (proxied by a score that measures gender inequalities in employment and education) and income inequality (proxied by income-based Gini coefficient). We also tested whether individual education or sub-city living conditions modified such associations. Higher city labor women's empowerment (in women) and higher city Gini coefficient (in men) were associated with a lower prevalence of overweight/obesity (PRR = 0.97 (95%CI 0.94, 0.99) and PRR = 0.94 (95%CI 0.90, 0.97), respectively). The associations varied by individual education and sub-city living conditions. For labor women's empowerment, we observed weakened associations towards the null effect in women with lower education and in residents of sub-cities with worse living conditions (men and women). For the Gini coefficient, the association was stronger among men with primary education, and a negative association was observed in women with primary education. Our findings highlight the need for promoting equity-based policies and interventions to tackle the high prevalence of excess weight in Latin American cities.
