Socioeconomic and racial/ethnic differentials of C-reactive protein levels: a systematic review of population-based studies
Background:Socioeconomic and racial/ethnic factors strongly influence cardiovascular disease outcomes and risk factors. C-reactive protein (CRP), a non-specific marker of inflammation, is associated with cardiovascular risk, and knowledge about its distribution in the population may help direct preventive efforts. A systematic review was undertaken to critically assess CRP levels according to socioeconomic and racial/ethnic factors.
Methods:Medline was searched through December 2006 for population-based studies examining CRP levels among adults with respect to indicators of socioeconomic position (SEP) and/or race/ethnicity. Bibliographies from located studies were scanned and 26 experts in the field were contacted for unpublished work.
Results:Thirty-two relevant articles were located. Cross-sectional (n = 20) and cohort studies (n = 11) were included, as was the control group of one trial. CRP levels were examined with respect to SEP and race/ethnicity in 25 and 15 analyses, respectively. Of 20 studies that were unadjusted or adjusted for demographic variables, 19 found inverse associations between CRP levels and SEP. Of 15 similar studies, 14 found differences between racial/ethnic groups such that whites had the lowest while blacks, Hispanics and South Asians had the highest CRP levels. Most studies also included adjustment for potential mediating variables in the causal chain between SEP or race/ethnicity and CRP. Most of these studies showed attenuated but still significant associations.
Conclusion: Increasing poverty and non-white race was associated with elevated CRP levels among adults. Most analyses in the literature are underestimating the true effects of racial/ethnic and socioeconomic factors due to adjustment for mediating factors
Global report on preterm birth and stillbirth (7 of 7): mobilizing resources to accelerate innovative solutions (Global Action Agenda)
<p>Abstract</p> <p>Background</p> <p>Preterm birth and stillbirth are complex local and global health problems requiring an interdisciplinary approach and an international commitment. Stakeholders developed recommendations for a Global Action Agenda (GAA) at the 2009 International Conference on Prematurity and Stillbirth. The primary goal of this GAA is to forge a collaborative effort toward achieving common goals to prevent preterm birth and stillbirth, and to improve related maternal, newborn, and child health outcomes.</p> <p>Conference participants</p> <p>GAPPS co-convened this four-day conference with the Bill & Melinda Gates Foundation, March of Dimes, PATH, Save the Children, UNICEF and the World Health Organization. Participants included about 200 leading international researchers, policymakers, health care practitioners and philanthropists. A near-final draft of this report was sent three weeks in advance to help co-chairs and participants prepare for workgroup discussions.</p> <p>Global Action Agenda</p> <p>Twelve thematic workgroups, composed of interdisciplinary experts, made recommendations on short-, intermediate-, and long-term milestones, and success metrics. Recommendations are based on the following themes: (1) advance discovery of the magnitude, causes and innovative solutions; (2) promote development and delivery of low-cost, proven interventions; (3) improve advocacy efforts to increase awareness that preterm birth and stillbirth are leading contributors to the global health burden; (4) increase resources for research and implementation; and (5) consider ethical and social justice implications throughout all efforts.</p> <p>Summary</p> <p>The conference provided an unprecedented opportunity for maternal, newborn and child health stakeholders to create a collaborative strategy for addressing preterm birth and stillbirth globally. Participants and others have already completed or launched work on key milestones identified in the GAA. Updates will be provided at www.gapps.org.</p
Iniqüidades sociais na saúde e nutrição de crianças em paÃses de renda baixa e média
OBJECTIVE: To describe the effects of social inequities on the health and nutrition of children in low and middle income countries. METHODS: We reviewed existing data on socioeconomic disparities within-countries relative to the use of services, nutritional status, morbidity, and mortality. A conceptual framework including five major hierarchical categories affecting inequities was adopted: socioeconomic context and position, differential exposure, differential vulnerability, differential health outcomes, and differential consequences. The search of the PubMed database since 1990 identified 244 articles related to the theme. Results were also analyzed from almost 100 recent national surveys, including Demographic Health Surveys and the UNICEF Multiple Indicator Cluster Surveys. RESULTS: Children from poor families are more likely, relative to those from better-off families, to be exposed to pathogenic agents; once they are exposed, they are more likely to become ill because of their lower resistance and lower coverage with preventive interventions. Once they become ill, they are less likely to have access to health services and the quality of these services is likely to be lower, with less access to life-saving treatments. As a consequence, children from poor family have higher mortality rates and are more likely to be undernourished. CONCLUSIONS: Except for child obesity and inadequate breastfeeding practices, all the other adverse conditions analyzed were more prevalent in children from less well-off families. Careful documentation of the multiple levels of determination of socioeconomic inequities in child health is essential for understanding the nature of this problem and for establishing interventions that can reduce these differences.OBJETIVO: Describir el efecto de las iniquidades sociales sobre la nutrición y salud de niños de paÃses de renta baja y media. MÉTODOS: Fueron revisadas informaciones disponibles sobre disparidades socioeconómicas intra-paÃses, relativas al uso de servicios de salud, estado nutricional, morbilidad y mortalidad. Se adoptó un modelo conceptual con cinco categorÃas jerárquicas en la producción de inequidades: contexto y posición socioeconómica, diferencias en la exposición, en la vulnerabilidad, en los hechos de salud y en las consecuencias. En investigación realizada en la base PubMed, en el perÃodo de 1990-2007 fueron encontrados 244 artÃculos relacionados al tema. Fueron también analizados los resultados de cerca de 100 pesquisas de ámbito nacional recientes, incluyendo Pesquisas Nacionales de DemografÃa y Salud y Pesquisas por Conglomerados de Múltiples Indicadores, del Fondo de las Naciones Unidas para la Infancia. RESULTADOS: Niños de familias pobres, en comparación con aquellas de familias más ricas, son más susceptibles a la exposición a agentes patogénicos; una vez expuestas, tienen un riesgo aumentado de enfermar, debido a su menor resistencia y menor cobertura de medidas preventivas. Una vez que se toman enfermos, tienen menor acceso a servicios de salud, la calidad de los servicios que logran utilizar tiende a ser inferior, con menor acceso a tratamientos médicos que garanticen su sobrevivencia. Como consecuencia, niños de familias más pobres presentan mayores tasas de mortalidad y mayor riesgo de ser subnutridas. CONCLUSIONES: Excepto obesidad infantil y prácticas inadecuadas de amamantamiento, todas las otras condiciones adversas analizadas tuvieron mayor prevalencia entre los niños de familias menos favorecidas. La documentación cuidadosa de los múltiples niveles de determinantes de las inequidades socioeconómicas en salud infantil es esencial para el entendimiento de la naturaleza del problema, y para el establecimiento de intervenciones que puedan reducir estas diferencias.OBJETIVO: Descrever o efeito das iniqüidades sociais sobre a nutrição e saúde de crianças de paÃses de renda baixa e média.

Vitamin A supplementation in Tanzania: the impact of a change in programmatic delivery strategy on coverage.
BACKGROUND\ud
\ud
Efficient delivery strategies for health interventions are essential for high and sustainable coverage. We report impact of a change in programmatic delivery strategy from routine delivery through the Expanded Programme on Immunization (EPI+) approach to twice-yearly mass distribution campaigns on coverage of vitamin A supplementation in Tanzania\ud
\ud
METHODS\ud
\ud
We investigated disparities in age, sex, socio-economic status, nutritional status and maternal education within vitamin A coverage in children between 1 and 2 years of age from two independent household level child health surveys conducted (1) during a continuous universal targeting scheme based on routine EPI contacts for children aged 9, 15 and 21 months (1999); and (2) three years later after the introduction of twice-yearly vitamin A supplementation campaigns for children aged 6 months to 5 years, a 6-monthly universal targeting scheme (2002). A representative cluster sample of approximately 2,400 rural households was obtained from Rufiji, Morogoro Rural, Kilombero and Ulanga districts. A modular questionnaire about the health of all children under the age of five was administered to consenting heads of households and caretakers of children. Information on the use of child health interventions including vitamin A was asked.\ud
\ud
RESULTS\ud
\ud
Coverage of vitamin A supplementation among 1-2 year old children increased from 13% [95% CI 10-18%] in 1999 to 76% [95%CI 72-81%] in 2002. In 2002 knowledge of two or more child health danger signs was negatively associated with vitamin A supplementation coverage (80% versus 70%) (p = 0.04). Nevertheless, we did not find any disparities in coverage of vitamin A by district, gender, socio-economic status and DPT vaccinations.\ud
\ud
CONCLUSION\ud
\ud
Change in programmatic delivery of vitamin A supplementation was associated with a major improvement in coverage in Tanzania that was been sustained by repeated campaigns for at least three years. There is a need to monitor the effect of such campaigns on the routine health system and on equity of coverage. Documentation of vitamin A supplementation campaign contacts on routine maternal and child health cards would be a simple step to facilitate this monitoring
Early life diarrhoea and later blood pressure in a developing country: the 1982 Pelotas (Brazil) birth cohort study
Background: It has recently been hypothesised that acute dehydration in early childhood may "programme'' increased blood pressure via salt retention. We examined whether there was an association between episodes of diarrhoea (a proxy for acute dehydration) and later measured blood pressure.Methods: In the 1982 Pelotas birth cohort study (Brazil), parents/carers reported hospital admissions for diarrhoea in the first 12 and 20 months of study members' lives. Blood pressure was subsequently measured directly in adolescence (aged 15, 18, 19 years) and early adulthood (aged 23 years).Results: We found no evidence of an association between diarrhoea in the first 12 months of life and blood pressure measured at any point in adolescence or early adulthood. These findings were unchanged after adjustment for a range of covariates. Equally null results were apparent when diarrhoea admissions in the first 20 months of life, access to home sanitation and use of piped water were the exposures of interest.Conclusions: Early life proxies for dehydration and diarrhoea were unrelated to later blood pressure in this examination, the most comprehensive to date, of the potential association
Sociedades justas: Una nueva visión para la equidad en la salud en la Región de las Américas después de la COVID19
Objective. Determine patterns of tuberculosis (TB) incidence indicators and number of deaths from TB within the framework of target 3.3 of the Sustainable Development Goals (SDGs) and their correlation with social determinants. Methods. Ecological study methodology was used, in which the population is the unit of analysis. Social determinants were analyzed using a negative binomial regression model and strength of association. Results. In the Americas, there was an average annual reduction in the TB incidence rate of 0.3% from 2009 to 2018; however, from 2015 to 2018, the rate increased, from 27.6 to 28.8 per 100,000 population. With regard to social determinants, the groups of countries with the lowest human development index (HDI) and gross domestic product (GDP) have a higher incidence of TB. TB risk in the country with the lowest HDI is six times that of the country with the highest HDI. Conclusions. At the current rate of reduction in the incidence rate and number of deaths from TB, the Region of the Americas will not meet the targets in the SDGs and in the End TB Strategy. Rapid implementation and expansion of interventions for TB prevention and control are required to attain the targets. This involves, among other actions, reducing access barriers to diagnosis and treatment and strengthening initiatives to address social determinants
