Regional equity in childhood health--register-based follow-up of the Finnish 1987 birth cohort

Our objective was to investigate regional health differences among Finnish children using a population-based longitudinal register data. All live births born in 1987 were included in the study (N=59,546) and followed-up until the age of seven years. Statistically significant regional variation was found for all health indicators but diabetes. Background variables, such as maternal age and social class, explained only the difference in mortality. Various indicators gave different geographical patterns. Regional equity in childhood health has not been achieved in Finland. Existing health registers were feasible in studying regional variation in health, but a set of comprehensive morbidity indicators - preferably derived from different data sources - should be developed to monitor equity in health.     

The equity lens in the health care performance evaluation system

The main objective of this paper is to describe how indicators of the equity of access to health care according to socioeconomic conditions may be included in a performance evaluation system (PES) in the regional context level and in the planning and strategic control system of healthcare organisations. In particular, the paper investigates how the PES adopted, in the experience of the Tuscany region in Italy, indicators of vertical equity over time. Studies that testify inequality of access to health services often remain just a research output and are not used as targets and measurements in planning and control systems. After a brief introduction to the concept of horizontal and vertical equity in health care systems and equity measures in PES, the paper describes the ‘equity process’ by which selected health indicators declined by socioeconomic conditions were shared and used in the evaluation of health care institutions and in the CEOs' rewarding system, and subsequently analyses the initial results. Results on the maternal and child path and the chronicity care path not only show improvements in addressing health care inequalities, but also verify whether the health system responds appropriately to different population groups.

Health indicators in Tunisia, trends in regional disparities over the last thirty years]

The measure of health indicators on a regional-scale seems more interesting then the measure on a national-scale. It allows us to study differences between regions and their evolution. In order to know the time trend's disparities between regions, we have studied seven indicators, concerning different types of the World Health Organisation's classification, using data from yearly statistics and results of decennial census. Regional disparities are evaluated by a ratio between the highest regional value and the lowest regional value. This study showed us a global trend to the decline of regional disparities about indicators that we have studied. The improvement of health care resources indicators and socioeconomic's indicators, in the process of time, is associated with the improvement of health status indicators. The study of regional disparities makes possible to target actions for health in order to promote health's equity between regions.     

Social class differences in health until the age of seven years among the Finnish 1987 birth cohort

Studies on social class differences in childhood health are controversial partly because of different data collection methods, limited sample sizes and the use of limited numbers of health indicators. The increasing collection of health register data enables the use of such data in social class studies. Our purpose was to investigate social class differences in mortality and morbidity among all children born in Finland in 1987 (N=59,865 liveborns) until the age of seven by using several national health registers, and to study whether perinatal health explains these differences. The follow-up was based on data linkage with six national health registers, with 18 regional registers of mentally disabled children, covering the whole country, and with 38 educational registers of the largest county. Morbidity was measured in terms of a cumulative disease index, the cumulative incidence of asthma, diabetes, epilepsy and intellectual disability, hospitalisations, disease-related welfare benefits and special education. Social class, divided in four groups (I–III, Others) was defined by using the mother's occupation at the time the child was seven years old. Our study showed that register-based data collection is a feasible method for studying social class differences in health. In the unadjusted analysis, social class differences were found for all indicators except mortality after the age of one year and for the cumulative incidence of asthma and diabetes. After adjusting for confounders, the children in the lowest social class had the highest risk for poor health outcome both in the perinatal period and in childhood, and had the most intellectual disabilities, the highest mean of hospitalisation days, and received the most special education. The differences were not explained by perinatal health. The health of the children in the lowest social class was poorer, especially regarding mental indicators.

The Sexual and Reproductive Health Burden Index: Development,Validity, and Community-Level Analyses of a Composite Spatial Measure

The Sexual and Reproductive Health Burden Index (SRHBI) was developed to provide a composite spatial measure of sexual and reproductive health (SRH) indicators that can be widely adopted by urban public health departments for the planning of SRH services. The index was constructed using eight indicators: teen births, low birthweight, infant mortality, new HIV diagnoses, people living with HIV, and incidences of gonorrhea, chlamydia, and syphilis. Chicago Department of Public Health data (2014–2017) were used to calculate index scores for Chicago community areas; scores were mapped to provide geovisualization and global Moran’s I was calculated to assess spatial autocorrelation. Cronbach’s alpha was calculated to assess internal reliability of the SRHBI. Pearson correlations were conducted to assess concurrent validity and correlation with community-level factors. Linear regression was conducted to assess community-level predictors of the SRHBI. Application of the SRHBI in Chicago demonstrates substantial variation in SRH burden across Chicago’s urban landscape with significant spatial autocorrelation of scores (I = .580, p = .001). Internal reliability of the measure was excellent with α = .937. The SRHBI was significantly correlated with other indicators of SRH including rate of prenatal care initiation in the first trimester, rate of preterm births, reported sexual assault incidence, cervical cancer incidence, prostate cancer incidence, and rate of smoking during pregnancy. This suggests good concurrent validity of the measure. Linear regression revealed that the percent of Black residents, percent of household couples that are same-sex, community violence, economic hardship, and population density were significant predictors of the SRHBI. The SRHBI provides a valid, useful, and replicable measure to assess and communicate community-level SRH burden in urban environments. The SRHBI may be scaled through a multi-city public data dashboard and utilized by urban public health departments to optimally target and tailor SRH interventions to communities.     

Impact of nitrates in drinking water on cancer mortality in Valencia,Spain

The concentrations of nitrates in public drinking water in the Mediterranean coastal province of Valencia are not only the highest in Spain but also in the whole of Europe. Intensive agricultural practices involve a traditional and growing use of nitrogen fertilizers. This and the terrain — poorly consolidated and porous in areas — favors the accumulation of nitrates in underground aquifers, thereby perhaps accounting for this contamination. The possible conversion of nitrates to nitrites under certain conditions of gastric achlorhydria, followed by their transformation to nitrosamines — substances known to be carcinogenic in experimental models — has led to a number of epidemiological studies of the possible relationship between high nitrate levels in public drinking water and mortality due to different cancers. The aim of the present study was to analyze the relationship between different levels of exposure to nitrates in the drinking water of the 258 municipalities in the province of Valencia and mortality due to cancer of the stomach, bladder, prostate and colon in this population. The cancer mortality rate was found to rise with increasing exposure to nitrates in the case of gastric cancer in both sexes, and in prostate cancer. These same results were obtained on calculating relative risk for the different age groups associated with the consumption of drinking water containing different levels of nitrates. Thus, in populations with nitrate concentrations in excess of 50 mg/1, relative risk for gastric cancer in the 55–75 years age group was 1.91 and 1.81 for males and females, respectively (p<0.05). In the case of prostate cancer elevated relative risks were also encountered: 1.86 and 1.80 for the 55–75 and over 75 years age groups, respectively.     

Regional risk factors for health inequalities in Scotland and England and the “Scottish effect”

This paper uses data from the Scottish Health Survey 2003 and the comparable Health Survey for England 2003 to look at whether Scotland's poor health image and mortality profile is reflected in regional inequalities in prevalence of four risk factors for cardiovascular disease: fruit and vegetable consumption, smoking, obesity and diabetes. It also looks at the “Scottish effect” – how much of any difference between and within Scotland and England remains once socio-demographic factors have been taken in to account. The paper then uses regional analyses to determine the extent to which areas within England and Scotland contribute to their national health advantage and disadvantage. All 2003 strategic health authorities in England and Scottish health boards were compared with Greater Glasgow health board as the reference category.The results showed that significant geographic variation in the risk factors remained once individual economic status was taken into account, but the relationship was complex and varied in strength and direction depending upon risk factor involved and gender of respondent. A small number of areas had significantly lower odds of fruit and vegetable consumption of five portions or more a day in men, compared with Greater Glasgow. In contrast some areas had significantly higher odds of fruit and vegetable consumption for women compared with Greater Glasgow.There was greater geographic variation in the odds of smoking in women than in men. Respondents in the south west and southeast of England (areas which usually show health advantage) did not show significantly lower odds of smoking compared with Greater Glasgow once socio-economic variation, age and urban residence was taken into account. It was respondents from central England that had lower odds of smoking than might be expected. Obesity stood out as the single risk factor that had demonstrated a “Scottish effect” in women only.     

Reference values for serum zinc and selenium of French healthy children

Age — and sex — specific reference intervals derived from a healthy pediatric population are presented for zinc, selenium and related analytes in serum. No strong correlations were found between age, sex and trace elements in serum. Serum variables were discussed to assess their ability as biochemical indicators of micronutrient status in the field of biological epidemiology.
