Burden of disease and costs of exposure to endocrine disrupting chemicals in the European Union: an updated analysis.

A previous report documented that endocrine disrupting chemicals contribute substantially to certain forms of disease and disability. In the present analysis, our main objective was to update a range of health and economic costs that can be reasonably attributed to endocrine disrupting chemical exposures in the European Union, leveraging new burden and disease cost estimates of female reproductive conditions from accompanying report. Expert panels evaluated the epidemiologic evidence, using adapted criteria from the WHO Grading of Recommendations Assessment, Development and Evaluation Working Group, and evaluated laboratory and animal evidence of endocrine disruption using definitions recently promulgated by the Danish Environmental Protection Agency. The Delphi method was used to make decisions on the strength of the data. Expert panels consensus was achieved for probable (>20%) endocrine disrupting chemical causation for IQ loss and associated intellectual disability; autism; attention deficit hyperactivity disorder; endometriosis; fibroids; childhood obesity; adult obesity; adult diabetes; cryptorchidism; male infertility, and mortality associated with reduced testosterone. Accounting for probability of causation, and using the midpoint of each range for probability of causation, Monte Carlo simulations produced a median annual cost of €163 billion (1.28% of EU Gross Domestic Product) across 1000 simulations. We conclude that endocrine disrupting chemical exposures in the EU are likely to contribute substantially to disease and dysfunction across the life course with costs in the hundreds of billions of Euros per year. These estimates represent only those endocrine disrupting chemicals with the highest probability of causation; a broader analysis would have produced greater estimates of burden of disease and costs.

Association of caesarean delivery with child adiposity from age 6 weeks to 15 years.

OBJECTIVES: o assess associations of caesarean section with body mass from birth through adolescence. DESIGN: ongitudinal birth cohort study, following subjects up to 15 years of age. SETTING AND PARTICIPANTS: Children born in 1991-1992 in Avon, UK who participated in the Avon Longitudinal Study of Parents and Children (ALSPAC) (n=10 219). PRIMARY OUTCOME: standardized measures of body mass (weight-for length z-scores at 6 weeks, 10 and 20 months; and body mass index (BMI) z-scores at 38 months, 7, 9, 11 and 15 years). Secondary outcome: categorical overweight or obese (BMI: 85th percentile) for age and gender, at 38 months, 7, 9, 11 and 15 years. RESULTS: Of the 10 219 children, 926 (9.06%) were delivered by caesarean section. Those born by caesarean had lower-birth weights than those born vaginally (-46.1 g, 95% confidence interval(CI): 14.6-77.6 g; P=0.004). In mixed multivariable models adjusting for birth weight, gender, parental body mass, family sociodemographics, gestational factors and infant feeding patterns, caesarean delivery was consistently associated with increased adiposity, starting at 6 weeks (+0.11 s.d. units, 95% CI: 0.03-0.18; P=0.005), through age 15 (BMI z-score increment+0.10 s.d. units, 95% CI: 0.001-0.198; P=0.042). By age 11 caesarean-delivered children had 1.83 times the odds of overweight or obesity (95% CI: 1.24-2.70; P=0.002). When the sample was stratified by maternal pre-pregnancy weight, the association among children born of overweight/obese mothers was strong and long-lasting. In contrast, evidence of an association among children born of normal-weight mothers was weak. CONCLUSION: Cesarean delivery is associated with increased body mass in childhood and adolescence. Research is needed to further characterize the association in children of normal weight women. Additional work is also needed to understand the mechanism underlying the association, which may involve relatively enduring changes in the intestinal microbiome.

Infant antibiotic exposures and early-life body mass.

OBJECTIVES: To examine the associations of antibiotic exposures during the first 2 years of life and the development of body mass over the first 7 years of life. DESIGN: Longitudinal birth cohort study. SUBJECTS: A total of 11 532 children born at 2500 g in the Avon Longitudinal Study of Parents and Children (ALSPAC), a population-based study of children born in Avon, UK in 1991-1992. MEASUREMENTS: Exposures to antibiotics during three different early-life time windows (<6 months, 6-14 months, 15-23 months), and indices of body mass at five time points (6 weeks, 10 months, 20 months, 38 months and 7 years). RESULTS: Antibiotic exposure during the earliest time window (<6 months) was consistently associated with increased body mass (+0.105 and +0.083 s.d. unit, increase in weight-for-length Z-scores at 10 and 20 months, P<0.001 and P=0.001, respectively; body mass index (BMI) Z-score at 38 months +0.067 s.d. units, P=0.009; overweight OR 1.22 at 38 months, P=0.029) in multivariable, mixed-effect models controlling for known social and behavioral obesity risk factors. Exposure from 6 to 14 months showed no association with body mass, while exposure from 15 to 23 months was significantly associated with increased BMI Z-score at 7 years (+0.049 s.d. units, P=0.050). Exposures to non-antibiotic medications were not associated with body mass. CONCLUSIONS: Exposure to antibiotics during the first 6 months of life is associated with consistent increases in body mass from 10 to 38 months. Exposures later in infancy (6-14 months, 15-23 months) are not consistently associated with increased body mass. Although effects of early exposures are modest at the individual level, they could have substantial consequences for population health. Given the prevalence of antibiotic exposures in infants, and in light of the growing concerns about childhood obesity, further studies are needed to isolate effects and define life-course implications for body mass and cardiovascular risks.

Actitudes, creencias y conocimientos de los pediatras sobre salud medioambiental en Murcia / Pediatrician attitudes, beliefs and knowledge about environmental health in Murcia, Spain

Objetivo: Estudiar las actitudes, las creencias y los conocimientos sobre salud medioambiental pediátrica (SMAP) de los pediatras de la Región de Murcia (RM). Método: Encuesta autocumplimentada, basada en los conocimientos teórico-prácticos sobre SMAP, enviada por correo postal en 2007 a los 293 pediatras que trabajan en la RM. Resultados: Respondieron 164 (56%). El 70% trabaja en atención primaria. El 5% pertenece a alguna organización no gubernamental medioambiental. Según los pediatras, los factores que más afectan a la salud infantil (sobre una puntuación máxima de 10) son: contaminantes del aire interior-tabaco (7,78), lesiones/accidentes (6,64) y contaminación del aire exterior (5,13). El 45% no registra información ambiental en las historias clínicas. Las consultas más frecuentes de los padres (de 1 a 4) son sobre lesiones y accidentes (2,16), radiación ultravioleta (2,06) y contaminación del agua de bebida (2,05). Las enfermedades respiratorias son las más relacionadas con la salud medioambiental. Conclusiones: Se debería asegurar que el contenido de la SMAP sea obligatorio en la enseñanza y la preparación de los futuros pediatras (pregrado, posgrado, formación continuada). Este trabajo podría ayudar a evaluar las necesidades y planificarlas acciones formativas en SMAP(AU)

Objective: To study pediatrician attitudes, beliefs and knowledge about pediatric environmental health (PEH) in the region of Murcia, Spain. Method: Were mailed a self administered survey based on theoretical and practical knowledge about issues related to PEH of 293 paediatricians working in the Region of Murcia. Results: The overall response rate was 56%. About 70% of respondents worked in Primary Care and 5% belonged to anon-governmental organization (NGO). Pediatricians stated that the factors most affecting the health of children (maximum score 10) were: indoor air pollutants (7.78) injuries and accidents (6.64), and outdoor air pollution (5.13). 45% did not systematically record information about the environments in the clinical registry. The most frequently asked questions by parents were (maximum score 4) related to: injuries and accidents (2.16), ultraviolet radiation (2.06) and contamination of drinking water (2.05). Pediatricians considered respiratory diseases to be most strongly related to the environment. Conclusions: Pediatric associations and institutions should include an EH syllabus in the curriculum of pregraduate and graduate students as well as in the continuing education of paediatricians. This work would help needs assessment and planning the training in PEH(AU)

Is severity of obesity associated with diagnosis or health education practices?

OBJECTIVE: To assess the association of the severity of obesity with diagnosis and health education, and to identify any differences within demographic or other subgroups. DESIGN: Clinician visits for 2-18 year olds from the 2005-2008 National Ambulatory Medical Care Survey and National Hospital Ambulatory Medical Care Survey were combined. Descriptive, bivariate and multivariate analyses were used to compare diagnosis of obesity and health education (nutrition, exercise and weight reduction) across elevated body mass index (BMI) groups (overweight, obese and extreme or very obese, defined as >120% of the 95th percentile for age and gender), patient socio-demographic characteristics, physician specialty and type of visit (well child visits (WCV) versus non-well child visits (non-WCV). RESULTS: A total of 17,808 visits had a calculated BMI, of which 5.8% were extremely obese, 13% were obese and 15.2% were overweight, with the highest percentages among older children, blacks and Hispanics. Diagnosis and weight reduction education were higher among children with an extreme BMI. Nutrition and exercise education were not correlated with severity of obesity. Race, ethnicity or gender biases were not identified. Severity of obesity was significantly associated with presentation to a non-WCV rather than a WCV. CONCLUSION: Extremely obese children have higher, but still insufficient, rates of diagnosis and health education. Nutrition and exercise education are not prevalent throughout all age groups. Providers may be relying inconsistently and insufficiently on visual cues to drive their obesity prevention practices. Furthermore, lower rates of diagnosis and education at non-WCV may result in a missed opportunity to prevent comorbidities. This is of particular concern as overweight children are less likely to be seen at WCV than non-WCV.
