Differences in Covid-19 mortality among persons 70 years and older in an integrated care setting in region Stockholm: a multi-level analysis between March 2020-February 2021.

BACKGROUND: In Norrtälje municipality, within Region Stockholm, there is a joint integrated care organisation providing health and social care, which may have facilitated a more coordinated response to the covid-19 pandemic compared to the otherwise decentralised Swedish system. This study compares the risk of covid-19 mortality among persons 70 years and older, in the municipalities of Stockholm, Södertälje, and Norrtälje, while considering area and individual risk factors. METHODS: A population-based study using linked register data to examine covid-19 mortality among those 70 + years (N = 127,575) within the municipalities of interest between the periods March-August 2020 and September 2020-February 2021. The effect of individual and area level variables on covid-19 mortality among inhabitants in 68 catchment areas were examined using multi-level logistic models. RESULTS: Individual factors associated with covid-19 mortality were sex, older age, primary education, country of birth and poorer health as indicated by the Charlson Co-morbidity Index. The area-level variables associated were high deprivation (OR: 1.56, CI: 1.18-2.08), population density (OR: 1.14, CI: 1.08-1.21), and usual care. Together, this explained 85.7% of the variation between catchment areas in period 1 and most variation was due to individual risk factors in period 2. Little of the residual variation was attributed to differences between catchment areas. CONCLUSION: Integrated care in Norrtälje may have facilitated a more coordinated response during period 1, compared to municipalities with usual care. In the future, integrated care should be considered as an approach to better protect and meet the care needs of older people during emergency situations.

Are the estimated needs for mental health care among adolescents from different socioeconomic backgrounds met equally in Sweden? A longitudinal survey-registry linkage study.

Evidence of inequality in the utilisation of mental health care (MHC) by adolescents in Nordic countries is mixed. This study aims to investigate if there are socioeconomic differences in the utilisation of MHC, while accounting for adolescents' mental health status. We analysed a cohort of 3517 adolescents, followed from 7 to 9th grade (ages 13-16), to examine the association between parental socioeconomic position (SEP: education and disposable income), adolescents' estimated needs, and the utilisation of MHC (defined as visits to secondary psychiatric care or receipt of psychotropic medication). Logistic and negative binomial regression models, with mental health status as moderator, were used to predict utilisation during each grade. Lower SEP predicted higher odds of utilising MHC in adolescents with no/mild symptoms (e.g., odds ratio, OR = 1.33, 95% CI 1.04-1.72, lower vs highest education), but not in those with moderate-to-severe symptoms (estimates close to one and non-significant). This pattern was largely explained by treatment of attention deficit hyperactivity disorder/autism spectrum disorders (ADHD/ASD) in boys. For girls with severe symptoms, lower SEP predicted reduced odds of utilising MHC for other mental disorders (OR = 0.48, 95% CI 0.25-0.92, lower education), and fewer outpatient visits when in contact with such care, although non-significant (incidence rate ratio, IRR = 0.51, 95% CI 0.25-1.05, lowest vs highest income). Our findings suggest a more equitable use of MHC for treating ADHD/ASD, but not other mental disorders such as depression and anxiety, particularly among girls.

Individual and neighborhood risk factors of hospital admission and death during the COVID-19 pandemic: a population-based cohort study.

BACKGROUND: The coronavirus disease 2019 (COVID-19) disproportionately affects minority populations in the USA. Sweden - like other Nordic countries - have less income and wealth inequality but lacks data on the socioeconomic impact on the risk of adverse outcomes due to COVID-19. METHODS: This population-wide study from March 2020 to March 2022 included all adults in Stockholm, except those in nursing homes or receiving in-home care. Data sources include hospitals, primary care (individual diagnoses), the Swedish National Tax Agency (death dates), the Total Population Register "RTB" (sex, age, birth country), the Household Register (size of household), the Integrated Database For Labor Market Research "LISA" (educational level, income, and occupation), and SmiNet (COVID data). Individual exposures include education, income, type of work and ability to work from home, living area and living conditions as well as the individual country of origin and co-morbidities. Additionally, we have data on the risks associated with living areas. We used a Cox proportional hazards model and logistic regression to estimate associations. Area-level covariates were used in a principal component analysis to generate a measurement of neighborhood deprivation. As outcomes, we used hospitalization and death due to COVID-19. RESULTS: Among the 1,782,125 persons, male sex, comorbidities, higher age, and not being born in Sweden increase the risk of hospitalization and death. So does lower education and lower income, the lowest incomes doubled the risk of death from COVID-19. Area estimates, where the model includes individual risks, show that high population density and a high percentage of foreign-born inhabitants increased the risk of hospitalization. CONCLUSIONS: Segregation and deprivation are public health issues elucidated by COVID-19. Neighborhood deprivation, prevalent in Stockholm, adds to individual risks and is associated with hospitalization and death. This finding is paramount for governments, agencies, and healthcare institutions interested in targeted interventions.

Detection and follow-up of chronic health conditions in Rio de Janeiro - the impact of residency training in family medicine.

BACKGROUND: There is a need for evidence that residency training in family medicine can benefit the care of patients in primary care in low- and middle-income countries. We tested the hypothesis that two years of residency training in family medicine enables doctors to better detect chronic health conditions while requesting fewer laboratory tests and providing more follow-up visits. METHODS: We performed a retrospective longitudinal observational analysis of medical consultations from 2013 to 2018 in primary care in Rio de Janeiro, comparing doctors without residency training in family medicine (Generalists) versus family physicians (FPs). Multivariate multilevel binomial regression models estimated the risks of patients being diagnosed for a list of 31 chronic health conditions, having a follow-up visit for these conditions, and having laboratory tests ordered from a list of 30 exams. RESULTS: 569.289 patients had 2.908.864 medical consultations performed by 734 generalists and 231 FPs. Patients seen by FPs were at a higher risk of being detected for most of the chronic health conditions, at a lower risk of having any of the 30 laboratory tests requested, and at a higher risk of having a follow-up visit in primary care. CONCLUSIONS: Residency training in family medicine can make physicians more skilled to work in primary care. Policymakers must prioritize investments in capacity building of healthcare workforce to make primary care truly comprehensive.

Impact of Integrated Care on the Rate of Hospitalization for Ambulatory Care Sensitive Conditions among Older Adults in Stockholm County: An Interrupted Time Series Analysis.

INTRODUCTION: Reducing avoidable hospital admissions is often viewed as a possible positive consequence of introducing integrated care (IC). The aim of this study was to investigate the impact of implementing IC in Norrtälje on the rate of admissions for ambulatory care sensitive conditions (ACSC). METHOD: Using interrupted time series analyses we investigated the effect of implementing IC in Norrtälje municipality in the northern part of Stockholm county, Sweden. The time period included 48 time points, from year 2000 to year 2011 with measurements before and after introducing IC in Norrtälje in 2006. In order to control for other extraneous events that could affect the outcome measure, but not related to the introduction of IC, we included a control population from Stockholm municipality. RESULTS: After introducing IC in Norrtälje the rate of admissions for ACSC decreased. This decrease was greater in Norrtälje than in the matched control population, however the difference between the two areas was not statistically significant (p = 0.08). CONCLUSION: Introducing IC in Norrtälje may have had positive impact on admissions for ACSC for older people living in Norrtälje; however, the interpretation of the impact of IC on admissions for ACSC is complicated by intervening policy changes in health and social care during the study period.

[Air pollution and the impacts on health in the Metropolitan Region of Belo Horizonte in the State of Minas Gerais, Brazil]. / Poluição do ar e impactos na saúde na Região Metropolitana de Belo Horizonte ­ Minas Gerais, Brasil.

The impact of air pollution on hospitalizations for total respiratory diseases (DRT) among children under five (DRC), as well as for cardiovascular diseases (CVD) in patients over 39 years of age, was examined in the municipalities of Belo Horizonte, Betim and Contagem, of the Metropolitan Region of Belo Horizonte, Minas Gerais. Generalized additive models using Poisson regression were used to adjust the daily time series of hospitalizations. Single and accumulated lagged pollutants of up to five days were introduced as independent variables and models were adjusted for temperature, humidity, weekdays and holidays. In Belo Horizonte PM10 was related to DRT (RR% 1.06 CI 95%: 0.41-1.72); DRC (%RR 1.25 CI 95%: 0.25-2.26) and CVD (RR% 2.29, CI 95%: 0.96-3.64). In Betim an RR% of 1.33 (CI 95%: 0.48-2.18) for DRT and RR% 2.38 (CI 95%: 1.20-3.56) for DRC was observed. In Contagem RR% = 1.23 (CI 95%: 0.32-2.15) and RR% = 1.61 (CI 95%: 0.26-2.96) was observed for DRT and DRC, respectively. SO2 and CO were also associated with hospitalizations. Respiratory diseases were the outcome most frequently related to air pollutants investigated. These results can be useful in discussions on emission control policies in the region.

Examinamos o impacto da poluição atmosférica nas internações por doenças respiratórias totais (DRT), em crianças menores de cinco anos (DRC) e por doenças cardiovasculares em maiores de 39 anos (DCV) nos municípios de Belo Horizonte (BH), Betim e Contagem, da Região Metropolitana de Belo Horizonte. Modelos aditivos generalizados via regressão de Poisson foram utilizados para ajustar as séries de hospitalizações. Os poluentes, em defasagem simples e acumulada de até cinco dias, foram introduzidos como variáveis independentes e os modelos foram ajustados para temperatura, umidade, dias da semana e feriados. Em BH, o PM10 esteve relacionado às DRT (RR% 1,06 IC95%:0,41-1,72); DRC (RR% 1,25 IC95%:0,25-2,26) e DCV (RR% 2,29 IC95%:0,96-3,64). Em Betim, observou-se RR% 1,33 (IC95%:0,48-2,18) para DRT e RR% 2,38 (IC95%:1,20-3,56) para DRC. Em Contagem, observou-se RR% 1,23 (IC95%:0,32-2,15) e RR% 1,61 (IC95%:0,26-2,96) para DRT e DRC, respectivamente. SO2 e CO também apresentaram associação com as hospitalizações. As doenças respiratórias foram o desfecho mais relacionado aos poluentes investigados. Esses resultados podem ser úteis nas discussões das políticas de controle de emissões na região.

Exposure to the use of firewood for cooking in Brazil and its relation with the health problems of the population. / Exposição ao uso da lenha para cocção no Brasil e sua relação com os agravos à saúde da população.

Indoor air pollution is exacerbated by the burning of firewood in rustic stoves and poorly ventilated environments. Exposure to the pollutants emitted by this type of fuel results in increased morbidity and mortality. In Brazil, studies and estimates regarding these conditions are scarce. In order to understand this problem, the objective of this work was to investigate the use of firewood using the data series of government agencies to estimate the number of exposed people. The results indicated that firewood is the second most used fuel for cooking, being used by a significant portion of the population, more than 30 million Brazilians. A decisive factor in the increased use of this fuel is the socioeconomic level of the population associated with the price of liquefied petroleum gas (LPG). The studies carried out in the country recorded high concentrations of particles during firewood burning, exceeding the limits suggested by the World Health Organization (WHO). Associations were also observed between the exposure to the pollutants generated by the burning and the aggravation of health problems, among them respiratory diseases and cancer. Replacing fuelwood and other solid fuels with cleaner fuels should be the government's goal to minimize health costs.

A poluição do ar em ambientes fechados é agravada pela queima de lenha em fogões rústicos e ambientes pouco ventilados. A exposição aos poluentes emitidos por este tipo de combustível resulta no aumento da morbidade e da mortalidade. No Brasil, os estudos e as estimativas são escassos. Visando entender esta problemática, o objetivo deste trabalho foi investigar o uso de lenha utilizando as séries de dados das agências governamentais para estimar o número de pessoas expostas. Os resultados apontam que a lenha é o segundo combustível mais usado para cozinhar, sendo utilizada por uma parcela significativa da população, em torno de 30 milhões de brasileiros. Um fator decisivo no maior uso deste combustível é o nível socioeconômico da população associada ao preço do gás liquefeito de petróleo (GLP). Os estudos realizados no país registraram concentrações altas de partículas durante a queima da lenha, excedendo os limites sugeridos pela Organização Mundial da Saúde (OMS). Também foram observadas associações entre a exposição aos poluentes gerados pela queima e o agravamento dos mais diversos problemas de saúde, dentre eles doenças respiratórias e câncer. A substituição da lenha e outros combustíveis sólidos por combustíveis mais limpos deve ser a meta do governo para minimizar custos com a saúde.

Prediction of cardiorespiratory fitness in the brazilian population aged 20 to 59 years: a non-exercise model approach with self-reported variables / Estimativa da aptidão cardiorrespiratória da população brasileira de 20 a 59 anos: abordagem por meio de modelo sem exercício com variáveis auto-relatadas

ABSTRACT Unlike other more common health-related variables, cardiorespiratory fitness (CRF) is not frequently measured in the general population. This omission characterizes a loss of relevant information. Thus, the objectives of the present study were: a) to characterize the CRF of the Brazilian population aged 20 to 59 years and to develop normative values using a non-exercise equation for predicting maximal oxygen uptake (VO2max), and b) to verify the association between lower levels of CRF and the prevalence of chronic diseases. A total of 32,531 individuals from the National Health Survey (NHS-IBGE-2013) composed the sample. Only self-reported variables were included in the equation of Wier et al. (2006): sex, age, physical activity level, and body mass index. The mean predicted VO2max was 44.6, 39.3, 34.8 and 30.6 ml/kg/min for men, and 34.5, 29.6, 25.4 and 21.1 ml/kg/min for women aged 20-29, 30-39, 40-49 and 50-59 years, respectively. The 20th and 80th percentiles were established as the extremes (very low and very high CRF). Participants with low fitness had a 33% higher chance of cardiovascular disease, an 89% higher chance of diabetes mellitus, and a 67% higher chance of hypertension, regardless of sex, age and presence of obesity, which seem to corroborate the quality of the equation.

RESUMO Diferentemente de outras variáveis mais comuns relacionadas à saúde, a aptidão cardiorrespiratória (ACR) não é medida constantemente na população em geral. Sua omissão caracteriza numa perda de informação relevante. Com isso os objetivos do presente estudo foram: a) caracterizar a ACR da população brasileira de 20 a 59 anos, desenvolvendo valores normativos através de uma equação para estimar o consumo máximo de oxigênio (VO2Máx) sem a realização de exercícios; e b) verificar a associação de menores níveis de ACR com a prevalência de doenças crônicas. Ao todo, 32.531 indivíduos compuseram a amostra oriunda da Pesquisa Nacional de Saúde (PNS-IBGE-2013). Apenas variáveis auto-relatadas foram incluídas a partir da equação de Wier et al. (2006): sexo, idade, nível de atividade física e Índice de Massa Corporal. A média de VO2Máx foi estimada como 44,6; 39,3; 34,8 e 30,6 ml/kg/min (homens) e 34,5; 29,6; 25,4 e 21,1 ml/kg/min (mulheres) com idades 20-29; 30-39; 40-49 e 50-59. Os valores de percentil 20 e 80 foram estabelecidos como os extremos de muito baixa e muito alta ACR. A baixa aptidão demonstrou significativamente 33% maiores chances de prevalência de doença cardiovascular, 89% de diabetes mellitus e 67% de hipertensão arterial independentemente de sexo, idade, e presença de obesidade, o que parece corroborar a qualidade da equação utilizada.

Thirty-year trends in dementia: a nationwide population study of Swedish inpatient records.

BACKGROUND: The continuous growth of the current dementia epidemic is contingent on the stability of age- and sex-specific trends over time. However, recent evidence suggests declining or stable trends. The aim of this study was to evaluate the real-world changes in the burden of dementia in older adults in Sweden from 1987 to 2016 by estimating age- and sex-specific incidence of dementia diagnosis in hospital inpatient records (dementia incidence). Differences in trends by sex, age, and educational levels were also examined. METHODS: The entire Swedish population aged 65 years and older was followed up from 1987 to 2016. Age-, sex-, and education-stratified dementia incidence rates for every follow-up year were estimated using the National Patient Register. Hazard ratio of receiving a dementia diagnosis in the inpatient records per 1 calendar year increase was estimated with discrete time logistic models with a complementary log-log link. RESULTS: After increase, especially in those >85 years of age, dementia incidence started to decrease in the last 5 years of the study period. After 2011, 1 calendar year increase was associated with lower hazard ratio of receiving a hospital diagnosis of dementia. The decrease had the highest magnitude in 70-74-year-olds (-5.5%), followed by 75-79-year-olds (-4.5%) and 80-84-year-olds (-4.0%). The decrease was present in both sexes and at all educational levels up to 90 years of age. Age was associated with the level of dementia incidence, and the trends differed by age group. Educational gradient was observed. University-educated older adults had the lowest rates of dementia. However, the trend over time did not substantially differ by sex or educational level. CONCLUSION: Our results provide more evidence that dementia incidence may be declining. They also suggest that at least in hospitals, the number of new patients with dementia may decrease in the future.

Does parity worsen diabetes-related chronic complications in women with type 1 diabetes?

AIM: To determine the relationship between parity, glycemic control, cardiovascular risk factors and diabetes-related chronic complications in women with type 1 diabetes. METHODS: This was a multicenter cross-sectional study conducted between December 2008 and December 2010 in 28 public clinics in 20 cities from the 4 Brazilian geographic regions. Data were obtained from 1532 female patients, 59.2% Caucasians, and aged 25.2 ± 10.6 years. Diabetes duration was of 11.5 ± 8.2 years. Patient's information was obtained through a questionnaire and a chart review. Parity was stratified in five groups: Group 0 (nulliparous), group 1 (1 pregnancy), group 2 (2 pregnancies), group 3 (3 pregnancies), group 4 (≥ 4 pregnancies). Test for trend and multivariate random intercept logistic and linear regression models were used to evaluate the effect of parity upon glycemic control, cardiovascular risk factors and diabetes-related complications. RESULTS: Parity was not related with glycemic control and nephropathy. Moreover, the effect of parity upon hypertension, retinopathy and macrovascular disease did not persist after adjustments for demographic and clinical variables in multivariate analysis. For retinopathy, the duration of diabetes and hypertension were the most important independent variables and for macrovascular disease, these variables were age and hypertension. Overweight or obesity was noted in a total of 538 patients (35.1%). A linear association was found between the frequency of overweight or obesity and parity (P = 0.004). Using a random intercept multivariate linear regression model with body mass index (BMI) as dependent variable a borderline effect for parity (P = 0.06) was noted after adjustment for clinical and demographic data. The observed variability of BMI was not attributable to differences between centers. CONCLUSION: Our results suggest that parity has a borderline effect on body mass index but does not have an important effect upon hypertension and micro or macrovascular chronic complications. Future prospective evaluations must be conducted to clarify the relationship between parity, appearance or worsening of diabetes-related chronic complications.

Air pollution and its impacts on health in Vitoria, Espirito Santo, Brazil.

OBJECTIVE: To analyze the impact of air pollution on respiratory and cardiovascular morbidity of children and adults in the city of Vitoria, state of Espirito Santo. METHODS: A study was carried out using time-series models via Poisson regression from hospitalization and pollutant data in Vitoria, ES, Southeastern Brazil, from 2001 to 2006. Fine particulate matter (PM10), sulfur dioxide (SO2), and ozone (O3) were tested as independent variables in simple and cumulative lags of up to five days. Temperature, humidity and variables indicating weekdays and city holidays were added as control variables in the models. RESULTS: For each increment of 10 µg/m3 of the pollutants PM10, SO2, and O3, the percentage of relative risk (%RR) for hospitalizations due to total respiratory diseases increased 9.67 (95%CI 11.84-7.54), 6.98 (95%CI 9.98-4.17) and 1.93 (95%CI 2.95-0.93), respectively. We found %RR = 6.60 (95%CI 9.53-3.75), %RR = 5.19 (95%CI 9.01-1.5), and %RR = 3.68 (95%CI 5.07-2.31) for respiratory diseases in children under the age of five years for PM10, SO2, and O3, respectively. Cardiovascular diseases showed a significant relationship with O3, with %RR = 2.11 (95%CI 3.18-1.06). CONCLUSIONS: Respiratory diseases presented a stronger and more consistent relationship with the pollutants researched in Vitoria. A better dose-response relationship was observed when using cumulative lags in polynomial distributed lag models.

RESUMO OBJETIVO Analisar o impacto da poluição atmosférica na morbidade respiratória e cardiovascular de crianças e adultos em Vitória. MÉTODOS Foi realizado estudo utilizando modelos de séries temporais via regressão de Poisson a partir de dados de hospitalizações e poluentes em Vitória, ES, de 2001 a 2006. Foram testadas como variáveis independentes o material particulado fino (PM10); o dióxido de enxofre (SO2) e o ozônio (O3) em defasagem simples e acumulada até cinco dias. Introduziu-se temperatura, umidade e variáveis indicadoras dos dias da semana e feriados da cidade como variáveis de controle nos modelos. RESULTADOS Para cada incremento de 10 µg/m3 dos poluentes PM10, SO2 e O3, foram observados aumentos no risco relativo percentual (RR%) para as hospitalizações por doenças respiratórias totais de 9,67 (IC95% 11,84-7,54), 6,98 (IC95% 9,98-4,17) e 1,93 (IC95% 2,95-0,93), respectivamente. Encontrou-se RR% = 6,60 (IC95% 9,53-3,75), RR% = 5,19 (IC95% 9,01-1,5) e RR% = 3,68 (IC95% 5,07-2,31) para doenças respiratórias em menores de cinco anos para o PM10, SO2 e O3, respectivamente. As doenças cardiovasculares apresentaram relação significativa com o O3 com RR% = 2,11 (IC95% 3,18-1,06). CONCLUSÕES As doenças respiratórias apresentaram relação mais forte e consistente com os poluentes pesquisados em Vitória. Observou-se melhor relação dose-resposta quando se utilizou defasagens acumuladas em modelos de distribuição polinomial.

Socioeconomic Status and in-hospital Mortality of Acute Coronary Syndrome: Can Education and Occupation Serve as Preventive Measures?

BACKGROUND: Socioeconomic status (SES) can greatly affect the clinical outcome of medical problems. We sought to assess the in-hospital mortality of patients with the acute coronary syndrome (ACS) according to their SES. METHODS: All patients admitted to Tehran Heart Center due to 1(st)-time ACS between March 2004 and August 2011 were assessed. The patients who were illiterate/lowly educated (≤5 years attained education) and were unemployed were considered low-SES patients and those who were employed and had high educational levels (>5 years attained education) were regarded as high-SES patients. Demographic, clinical, paraclinical, and in-hospital medical progress data were recorded. Death during the course of hospitalization was considered the end point, and the impact of SES on in-hospital mortality was evaluated. RESULTS: A total of 6246 hospitalized patients (3290 low SES and 2956 high SES) were included (mean age = 60.3 ± 12.1 years, male = 2772 [44.4%]). Among them, 79 (1.26%) patients died. Univariable analysis showed a significantly higher mortality rate in the low-SES group (1.9% vs. 0.6%; P < 0.001). After adjustment for possible cofounders, SES still showed a significant effect on the in-hospital mortality of the ACS patients in that the high-SES patients had a lower in-hospital mortality rate (odds ratio: 0.304, 95% confidence interval: 0.094-0.980; P = 0.046). CONCLUSIONS: This study found that patients with low SES were at a higher risk of in-hospital mortality due to the ACS. Furthermore, the results suggest the need for increased availability of jobs as well as improved levels of education as preventive measures to curb the unfolding deaths owing to coronary artery syndrome.

A repeated measurement study investigating the impact of school outdoor environment upon physical activity across ages and seasons in Swedish second, fifth and eighth graders.

BACKGROUND: School children are confined to and exposed to outdoor environment that happens to be at their disposal during compulsory school time. The health-promoting potential of outdoor environment, and the use of it, is therefore important. We have studied the impact of school outdoor environment in terms of playground features, space, topography and vegetation upon the patterns of moderate to vigorous physical activity (MVPA) across ages and seasons in Swedish pupils at compulsory school. METHODS: Four schools in the Middle and Southern parts of Sweden, with outdoor environments differing in playground features, space, topography and vegetation were analyzed during one school year. A sample of 196 children was drawn from eligible pupils in grades 2, 5 and 8, aged 7-14 years. PA was monitored with time-stamped Actigraph accelerometers GT3X+, measuring different intensity levels during outdoor time. Maps were used to mark places where the children stayed and what they did during outdoor time. RESULTS: Mean MVPA during outdoor stay was 39 minutes for the entire school year, time in MVPA correlated positively with outdoor time, as did MVPA with used outdoor play area (p < 0.001). Outdoor MVPA declined with age, boys accumulated more MVPA than girls at all ages (p < 0.001). Ball play areas increased MVPA in 5th graders in September and May (p < 0.001). Overall, ball play areas increased 5th graders' relative MVPA, and helped maintaining it with increasing age in boys but not in girls, whereas woodland stimulated and contributed to maintaining girls' MVPA with increasing age. Outdoor temperature significantly impacted (p < 0.01) MVPA throughout all seasons. CONCLUSION: We conclude that school outdoor environment design and outdoor play time impact physical activity on a daily basis and may contribute to increasing girls' physical activity and moderate the sharp decline in physical activity by age. The school outdoor environment may thus be a potential health promoter during school time.

Individual and community-level socioeconomic position and its association with adolescents experience of childhood sexual abuse: a multilevel analysis of six countries in Sub-Saharan Africa.

BACKGROUND: Childhood sexual abuse (CSA) is a substantial global health and human rights problem and consequently a growing concern in sub-Saharan Africa. We examined the association between individual and community-level socioeconomic status (SES) and the likelihood of reporting CSA. METHODS: We applied multiple multilevel logistic regression analysis on Demographic and Health Survey data for 6,351 female adolescents between the ages of 15 and 18 years from six countries in sub-Saharan Africa, between 2006 and 2008. RESULTS: About 70% of the reported cases of CSA were between 14 and 17 years. Zambia had the highest proportion of reported cases of CSA (5.8%). At the individual and community level, we found that there was no association between CSA and socioeconomic position. This study provides evidence that the likelihood of reporting CSA cut across all individual SES as well as all community socioeconomic strata. CONCLUSIONS: We found no evidence of socioeconomic differentials in adolescents' experience of CSA, suggesting that adolescents from the six countries studied experienced CSA regardless of their individual- and community-level socioeconomic position. However, we found some evidence of geographical clustering, adolescents in the same community are subject to common contextual influences. Further studies are needed to explore possible effects of countries' political, social, economic, legal, and cultural impact on childhood sexual abuse.

Poluição do ar em cidades brasileiras: selecionando indicadores de impacto na saúde para fins de vigilância* / Air pollution in Brazilian cities: selecting health impact indicators for surveillance

Objetivo: avaliar o impacto da poluição atmosférica na saúde, em municípios brasileiros, e selecionar indicadores de efeito para fins de vigilância. Métodos: a partir de dados de hospitalizações e material particulado fino (PM10), foi realizado estudo utilizando modelos de séries temporais, em particular Modelos Aditivos Generalizados com regressão de Poisson, para estimar o impacto da poluição do ar na saúde. Foram analisadas as internações por doenças respiratórias totais (DRT); internações por doenças respiratórias em menores de 5 anos (DRC) e internações por doenças cardiovasculares em adultos maiores de 39 anos (DCV), em 21 cidades. O melhor indicador de efeito foi selecionado a partir da proporção de resultados significativos. Resultados: foi encontrada relação significativa em 81 por cento das localidades para DRT; 89 por cento para DRC; e 50 por cento para DCV. Conclusões: o indicador DRC foi considerado o melhor indicador de efeito, seguido pelo indicador DRT. Conclui-se que ambos podem ser utilizados para fins de vigilância.

Objective: to assess the health impact of air pollution in Brazilian cities and to select effect indicators for surveillance purposes. Methods: based on hospital inpatient and fine particulate matter (PM10) data, a study was performed using time series models, in particular Generalized Additive Models with Poisson regression to estimate the impact of air pollution on health. We analyzed hospital admissions for total respiratory illnesses (TRI), admissions for respiratory diseases in children under 5 years old (RDC) and admissions for cardiovascular diseases in adults (CVD) in 21 cities. The best effect indicator was selected based on the proportion of statistically significant results. Results: we found a significant relationship in 81 per cent of locations for TRI, 89 per cent for RDC and 50 per cent for CVD. Conclusions: significant relationships were found for most cities. RDC were considered the best effect indicator, closely followed by TRI. Both can therefore be used for surveillance purposes.

Is gender policy related to the gender gap in external cause and circulatory disease mortality? A mixed effects model of 22 OECD countries 1973-2008.

BACKGROUND: Gender differences in mortality vary widely between countries and over time, but few studies have examined predictors of these variations, apart from smoking. The aim of this study is to investigate the link between gender policy and the gender gap in cause-specific mortality, adjusted for economic factors and health behaviours. METHODS: 22 OECD countries were followed 1973-2008 and the outcomes were gender gaps in external cause and circulatory disease mortality. A previously found country cluster solution was used, which includes indicators on taxes, parental leave, pensions, social insurances and social services in kind. Male breadwinner countries were made reference group and compared to earner-carer, compensatory breadwinner, and universal citizen countries. Specific policies were also analysed. Mixed effect models were used, where years were the level 1-units, and countries were the level 2-units. RESULTS: Both the earner-carer cluster (ns after adjustment for GDP) and policies characteristic of that cluster are associated with smaller gender differences in external causes, particularly due to an association with increased female mortality. Cluster differences in the gender gap in circulatory disease mortality are the result of a larger relative decrease of male mortality in the compensatory breadwinner cluster and the earner-carer cluster. Policies characteristic of those clusters were however generally related to increased mortality. CONCLUSION: Results for external cause mortality are in concordance with the hypothesis that women become more exposed to risks of accident and violence when they are economically more active. For circulatory disease mortality, results differ depending on approach--cluster or indicator. Whether cluster differences not explained by specific policies reflect other welfare policies or unrelated societal trends is an open question. Recommendations for further studies are made.

A comparative study of the socioeconomic factors associated with childhood sexual abuse in sub-Saharan Africa.

BACKGROUND: Childhood sexual abuse (CSA) is a problem of considerable proportion in Africa where up to one-third of adolescent girls report their first sexual experience as being forced. The impact of child hood sexual abuse resonates in all areas of health. The aim of this study was to describe the prevalence of childhood sexual abuse and variations across socioeconomic status in six sub-Saharan countries. METHODS: Datasets from Demographic and Health Surveys (DHS) in six sub-Saharan African countries conducted between 2003 and 2007 were used to access the relationship between CSA and socio economic status using multiple logistic regression models. RESULTS: There was no association between CSA and education, wealth and area of settlement. However, there was contrasting association between CSA and working status of women. CONCLUSION: This study concurs with other western studies which indicate that CSA transcends across all socio economic group. It is therefore important that effective preventive strategies are developed and implemented that will cross across all socio-economic groups.
