    Background: An estimated 23 million infants are still not being benefitted from routine immunization services. We assessed how many children failed to be fully immunized even though they or their mothers were in contact with health services to receive other interventions. Design: Fourteen countries with Demographic and Health Surveys and Multiple Indicator Cluster Surveys carried out after 2000 and with coverage for DPT (Diphtheria-tetanus-pertussis) vaccine below 70% were selected. We defined full immunization coverage (FIC) as having received one dose of BCG (bacille Calmette-Guérin), one dose of measles, three doses of polio, and three doses of DPT vaccines. We tabulated FIC against: antenatal care (ANC), skilled birth attendance (SBA), postnatal care for the mother (PNC), vitamin A supplementation (VitA) for the child, and sleeping under an insecticide-treated bed-net (ITN). Missed opportunities were defined as the percentage of children who failed to be fully immunized among those receiving one or more other interventions. Results: Children who received other health interventions were also more likely to be fully immunized. In nearly all countries, FIC was lowest among children born to mothers who failed to attend ANC, and highest when the mother had four or more ANC visits Côte d'Ivoire presented the largest difference in FIC: 54 percentage points (pp) between having four or more ANC visits and lack of ANC. SBA was also related with higher FIC. For instance, the coverage in children without SBA was 36 pp lower than for those with SBA in Nigeria. The largest absolute difference on FIC in relation to PNC was observed for Ethiopia: 31 pp between those without and with PNC. FIC was also positively related with having received VitA. The largest absolute difference was observed in DR Congo: 41 pp. The differences in FIC among whether or not children slept under ITN were much smaller than for other interventions. Haiti presented the largest absolute difference: 16 pp. Conclusions: Our results show the need to develop and implement strategies to vaccinate all children who contact health services in order to receive other interventions

    OBJECTIVE: To investigate disparities in full immunization coverage across and within 86 low- and middle-income countries. METHODS: In May 2015, using data from the most recent Demographic and Health Surveys and Multiple Indicator Cluster Surveys, we investigated inequalities in full immunization coverage – i.e. one dose of bacille Calmette-Guérin vaccine, one dose of measles vaccine, three doses of vaccine against diphtheria, pertussis and tetanus and three doses of polio vaccine – in 86 low- or middle-income countries. We then investigated temporal trends in the level and inequality of such coverage in eight of the countries. FINDINGS: In each of the World Health Organization’s regions, it appeared that about 56–69% of eligible children in the low- and middle-income countries had received full immunization. However, within each region, the mean recorded level of such coverage varied greatly. In the African Region, for example, it varied from 11.4% in Chad to 90.3% in Rwanda. We detected pro-rich inequality in such coverage in 45 of the 83 countries for which the relevant data were available and pro-urban inequality in 35 of the 86 study countries. Among the countries in which we investigated coverage trends, Madagascar and Mozambique appeared to have made the greatest progress in improving levels of full immunization coverage over the last two decades, particularly among the poorest quintiles of their populations. CONCLUSION: Most low- and middle-income countries are affected by pro-rich and pro-urban inequalities in full immunization coverage that are not apparent when only national mean values of such coverage are reported

    Em um contexto de baixo investimento em saneamento, Teixeira e Guilhermino (2006) estudaram a associação entre as condições de saneamento e os indicadores epidemiológicos nos estados brasileiros, utilizando dados secundários do banco de dados IDB (2003) do Ministério da Saúde. A partir de 2003, os investimentos em saneamento básico no Brasil aumentaram. Assim, o presente trabalho teve como objetivo testar a hipótese de que a ampliação da cobertura por serviços de saneamento básico no período entre 2001 e 2006 foi um investimento capaz de melhorar os indicadores de saúde nos estados brasileiros. Concluiu-se que houve melhoria nos indicadores de saúde, porém não-expressiva, sendo fundamental a utilização de indicadores epidemiológicos e de desenvolvimento social na decisão sobre a priorização de investimentos em saneamento no Brasil.In a context of poor investment in sanitation, Teixeira e Guilhermino (2006) studied the association between the sanitation conditions and the epidemiological indicators in the Brazilian states, based on secondary data from the database from IDB (2003) of the Ministry of Health. Since 2003, investments in basic sanitation in Brazil had an expressive increase. Thus, the present paper had as a purpose to test the hypothesis that the improvement in the coverage by basic sanitation services from 2001 to 2006 was an investment capable to improve the studied health indicators in the Brazilian states. It has been concluded that there was an improvement in the health indicators, which is still not expressive, being of the most importance the use of epidemiological and social development indicators in the priority of investments in basic sanitation in Brazil

    O presente estudo investigou a prática de esportes individuais e coletivos e fatores associados em jovens com idade média de 11 anos, pertencentes a uma coorte de nascimentos. Informações dos jovens e de suas mães foram coletadas por meio de questionários. O desfecho foi dividido em prática de esportes individuais e coletivos. Uma análise por meio de regressão de Poisson foi conduzida para estabelecer os fatores associados à prática esportiva, obedecendo a um modelo conceitual de análise com as variáveis independentes hierarquizadas. Um total de 4350 jovens foi estudado. A prática de esportes coletivos foi menor nas meninas - 68,1% (IC95% 66,2 - 70,0) em comparação aos meninos - 82,1% (IC95% 80,5 - 83,7). Nos esportes individuais, a prevalência foi de 12,9% (IC95% 11,6 - 14,4) e 18,9% (IC95% 17,3 - 20,6) em meninas e meninos, respectivamente. Entre as meninas, a prática de esportes individuais relacionou-se diretamente com nível econômico e inversamente com assistir televisão. Nos meninos este desfecho associou-se com estudar em escolas privadas e ter mães fisicamente ativas. Em esportes coletivos, a prática foi menor naqueles que despendem maior tempo assistindo TV. Em ambos os sexos houve uma relação direta entre o uso regular do vídeo-game e a prática de esportes. Políticas públicas devem considerar os diferentes aspectos relacionados à prática esportiva e atender a disparidades socioeconômicas no acesso a diferentes modalidades esportivas. Além disso, o maior acesso a diferentes locais de práticas esportivas, bem como o incentivos de pais, amigos e ambiente escolar devem ser fortalecidos.The present study investigated individual and collective sports practice and associated factors among adolescents with a mean age of 11 years, belonging to a birth cohort study. Information on the adolescents and on their mothers were obtained through questionnaires. The outcome variable was divided into practice of individual and collective sports. Poisson regression models were used in order to determine the factors associated with sports practice, following a hierarchical framework. A total of 4350 adolescents were interviewed. Practice of collective sports was less frequent among girls - 68.1% (95%CI 66.2 - 70.0) in comparison to boys- 82.1% (95%CI 80.5 - 83.7). Regarding individual sports, the prevalence was 12.9% (95%CI 11.6 - 14.4) and 18.9% (95%CI 17.3 - 20.6) in girls and boys, respectively. Among girls, individual sports practice was directly associated with socioeconomic level and inversely with television viewing. Among boys, the outcome was associated with studying in private schools and having an active mother. In terms of collective sports, the practice was less frequent among those with high level of television viewing. In both sexes, a direct association was observed between videogame playing and sports practice. Public policies should consider the different aspects related to sports practice and consider socioeconomic inequalities in sports practice

    BACKGROUND: Growth faltering has been associated with poor intellectual performance. The relative strengths of associations between growth in early and in later childhood remain underexplored. OBJECTIVES: We examined the association between growth in childhood and adult human capital in 5 low- and middle-income countries (LMICs). METHODS: We analyzed data from 9503 participants in 6 prospective birth cohorts from 5 LMICs (Brazil, Guatemala, India, the Philippines, and South Africa). We used linear and quasi-Poisson regression models to assess the associations between measures of height and relative weight at 4 age intervals [birth, age ∼2 y, midchildhood (MC), adulthood] and 2 dimensions of adult human capital [schooling attainment and Intelligence Quotient (IQ)]. RESULTS: Meta-analysis of site- and sex-specific estimates showed statistically significant associations between size at birth and height at ∼2 y and the 2 outcomes (P < 0.001). Weight and length at birth and linear growth from birth to ∼2 y of age (1 z-score difference) were positively associated with schooling attainment (β: 0.13; 95% CI: 0.08, 0.19, β: 0.17; 95% CI: 0.07, 0.32, and β: 0.25, 95% CI: 0.10, 0.40, respectively) and adult IQ (β: 0.74, 95% CI: 0.35, 1.14, β: 0.73, 95% CI: 0.35, 1.10, and β: 1.52, 95% CI: 0.96, 2.08, respectively). Linear growth from age 2 y to MC and from MC to adulthood was not associated with higher school attainment or IQ. Change in relative weight in early childhood, MC, and adulthood was not associated with either outcome. CONCLUSIONS: Linear growth in the first 1000 d is a predictor of schooling attainment and IQ in adulthood in LMICs. Linear growth in later periods was not associated with either of these outcomes. Changes in relative weight across the life course were not associated with schooling and IQ in adulthood
