Cadmium (Cd) and Lead (Pb) topsoil levels and incidence of childhood leukemias.

There are few well-established risk factors for childhood leukemias. While the frequency of childhood leukemias might be partially attributable to some diseases (accounting for a small fraction of cases) or ionizing radiation, the role of heavy metals has not been assessed. The objective of our study was to assess the potential association between levels of cadmium (Cd) and lead (PB) in soil and childhood leukemias incidence. We conducted a population-based case-control study of childhood leukaemia in Spain, covering 2897 incident cases gathered from the Spanish Registry of Childhood Tumours and including 14 Spanish Regions with a total population of 5,307,433 children (period 1996-2015). Cd and Pb bioavailable levels at every children's home address were estimated using data from the Geochemical Atlas of Spain. We used logistic regression to estimate odds ratios (ORs) and their 95% confidence intervals (95%CIs); we included as covariates: sex, rurality, employment rate and socioeconomic status. Metal levels were analysed according to two definitions: as continuous variable assuming linearity and as categorical variables to explore a potentially nonlinear association (quantiles). Increases in both Cd and Pb topsoil levels were associated with increased probability of childhood leukemias incidence. The results for the models with the continuous variables showed that a unit increase on the topsoil level was associated with an OR of 1.11 for Cd (95%CI 1.00-1.24) and an OR of 1.10 for Pb (95%CI 0.99-1.21). Our study may point towards a possible link between residential Cd and Pb topsoil levels and the probability of childhood leukemias incidence. Residing in a location with the highest concentrations of these heavy metals compared to those locations with the lowest could increase the risk around a 20%, for both Cd and Pb.

Review of the questionnaries used to detect alcohol consumption during pregnancy and the Green Page. / Revisión de los cuestionarios utilizados para la detección del consumo de alcohol durante el embarazo y la Hoja Verde.

Alcohol consumption during pregnancy is a leading cause of fetal alcohol spectrum disorder (FASD). Maternal reporting in childbearing women or pregnant women is the standard for the early detection of alcohol consumption. The Green Page (GP) is a screening questionnaire of environmental health which includes the alcohol intake record during pregnancy and/or lactation period. The aim of this paper is to review the features of the different questionnaires for the detection of alcohol consumption during the gestation period and the GP, as well as to make a comparison between them. Review of the scientific literature published over the last 10 years of indexed articles in Medline. Combined searching strategy with MeSH descriptors: 'pregnancy, alcohol drinking, surveys and/or questionnaires. AUDIT, AUDIT-C and SURP-P are mainly self-administered and do not require training. SURP-P and 4P´s are validated in pregnant women. Others detect quantity and frequency of exposure, need specific training and are administered face to face: TLFB, RD, ACOG antepartum record and the GP. ACOG antepartum record and GP are specific for pregnant population. GP detects alcohol consumption at the beginning of pregnancy in both women and their partner on a holistic and global environmental health approach. A careful face-to-face recording of alcohol exposure with trained staff, with an integrative and global environmental health focus throughout pregnancy, may help improve prevention and screening of pregnancy at risk for FASD.

El consumo de alcohol en el embarazo es la causa del trastorno del espectro alcohólico fetal (TEAF). La información aportada por las mujeres en edad fértil o embarazadas es el estándar para la detección temprana del consumo de alcohol. La Hoja Verde (HV) es una herramienta de cribado de salud medioambiental que incluye el registro de la ingesta de alcohol durante el embarazo y/o lactancia. El objetivo del presente trabajo es revisar las características de los distintos cuestionarios de detección del consumo de alcohol durante la gestación y de la HV, así como hacer una comparación entre ellos. Revisión de la literatura científica publicada en los últimos 10 años de los artículos indexados en Medline. Estrategia de búsqueda combinada con los descriptores MeSH: 'pregnancy, alcohol drinking, surveys and/or questionnaires'. AUDIT, AUDIT-C y SUPR-P se realizan mayoritariamente autoadministrados y no requieren entrenamiento. SUPR-P y 4P´s Plus están validados en embarazadas. Otros detectan cantidad y frecuencia, requieren entrenamiento previo y se realizan cara a cara: TLFB, RD, ACOG antepartum record y la HV. ACOG antepartum record y la HV son específicos para embarazadas. La HV detecta el consumo de alcohol al inicio del embarazo tanto en la gestante como en su pareja con un enfoque holístico y global de la salud medioambiental. Un cuidadoso registro de la ingesta de alcohol de forma presencial, con profesionales entrenados y con un enfoque holístico y global de la salud medioambiental durante el embarazo ayudaría a mejorar la prevención y cribado de embarazos en riesgo de TEAF.

An Integrative Screening Tool of Alcohol Exposure During Early Pregnancy: Combining of the CDT Biomarker with Green Page Questionnaire.

AIMS: In current clinical practice, prenatal alcohol exposure is usually assessed by interviewing the pregnant woman by applying questionnaires. An alternative method for detecting alcohol use is to measure the biomarker carbohydrate-deficient transferrin (CDT). However, few studies measure CDT during pregnancy. This study examines the utility of CDT biomarker in the screening of alcohol exposure during early pregnancy. METHODS: A cohort of 91, first-trimester pregnant women assigned to a public reference maternity hospital, was screened using the Green Page (GP) questionnaire, an environmental exposure tool. CDT levels and other biomarkers of alcohol use were measured and compared with questionnaire data. RESULTS: About 70% of the mothers in the study consumed alcohol during early pregnancy and 22% met high-risk criteria for prenatal exposure to alcohol. CDT measurement showed a statistically significant area under the receiver operating characteristic curve with a value of 0.70. For a value of 0.95% of CDT, a specificity of 93% was observed. The most significant predictors of CDT were the number of binge drinking episodes, women's body mass index and European white race. CONCLUSION: Pregnant women with a CDT value >0.95% would be good candidates for the performance of the GP questionnaire during early pregnancy in order to detect potential high-risk pregnancy due to alcohol exposure.

Long term follow-up of a tobacco prevention and cessation program in cystic fibrosis patients. / Seguimiento a largo plazo de un programa de prevención y cesación tabáquica en pacientes con fibrosis quística.

This study evaluates the impact over time of a telephone-based intervention in tobacco cessation and prevention targeting patients with cystic fibrosis (CF) in the Mediterranean region of Murcia, Spain. We conducted an experimental prospective study with a cohort of CF patients using an integrative smoking cessation programme, between 2008 and 2013. The target population included family members and patients from the Regional CF unit. The study included an initial tobacco exposure questionnaire, measurement of lung function, urinary cotinine levels, anthropomorphic measures and the administered intervention at specific time intervals. Of the 88 patients tracked through follow-up, active smoking rates were reduced from 10.23% to 4.55% (p = 0.06). Environmental tobacco exposure was reduced in non-smoker patients from 62.03% to 36.90% (p < 0.01) during the five year follow-up. Significant reductions in the gradient of household tobacco smoke exposure were also observed with a decrease of 12.60%, from 31.65% (n = 25/79) to 19.05% (n = 16/84) in 2013 (p = <0.01). Cotinine was significantly correlated with both active and passive exposure (p<0.01) with a significant reduction of cotinine levels from 63.13 (28.58-97.69) to 20.56 (0.86-40.27) ng/ml (p<0.01). The intervention to significantly increase the likelihood of family quitting (smoke-free home) was 1.26 (1.05-1.54). Telephone based interventions for tobacco cessation and prevention is a useful tool when applied over time. Trained intervention professionals in this area are needed in the environmental health approach for the treatment of CF.

Este estudio evalúa el impacto en el tiempo de una intervención telefónica de prevención y cesación tabáquica dirigida a pacientes con fibrosis quística (FQ) en la Región de Murcia, España. Estudio prospectivo experimental en una cohorte de pacientes con FQ utilizando un programa integrativo de cesación tabáquica, entre 2008 y 2013. La población diana incluye a pacientes y familiares de la unidad regional de FQ. El estudio incluyó un cuestionario inicial de exposición al tabaco, medición de la función pulmonar, niveles de cotinina en orina, medidas antropomórficas y la intervención realizada en intervalos de tiempo.De los 88 pacientes seguidos, la tasa de fumadores activos se redujo de 10,23% a 4,55% (p = 0,06). La exposición al humo ambiental de tabaco se redujo en los pacientes no fumadores de 62,03% a 36,90% (p < 0,01) durante los cinco años de seguimiento. Se observaron reducciones significativas en la exposición al humo ambiental de tabaco en los hogares, de 31,65% (n = 25/79) a 19,05% (n = 16/84) en 2013 (p = <0,01). La cotinina se correlacionó significativamente con la exposición al tabaco activa y pasiva (p < 0,01) con una reducción significativa de los niveles de cotinina de 63,13 (28,58-97,69) a 20,56 (0,86-40,27) ng/ml (p < 0,01). La intervención para aumentar significativamente la probabilidad de abandono familiar (hogar libre de humo) fue de 1,26 (1,05-1,54). La intervención telefónica mantenida en el tiempo es una herramienta útil para la prevención y cesación tabáquica. Profesionales entrenados en este modelo de intervención con enfoque en salud medioambiental son necesarios para mejorar el tratamiento de FQ.

Exploring Urban Green Spaces' Effect against Traffic Exposure on Childhood Leukaemia Incidence.

BACKGROUND: Several environmental factors seem to be involved in childhood leukaemia incidence. Traffic exposure could increase the risk while urban green spaces (UGS) exposure could reduce it. However, there is no evidence how these two factors interact on this infant pathology. OBJECTIVES: to evaluate how residential proximity to UGS could be an environmental protective factor against traffic exposure on childhood leukaemia incidence. METHODS: A population-based case control study was conducted across thirty Spanish regions during the period 2000-2018. It included 2526 incident cases and 15,156, individually matched by sex, year-of-birth, and place-of-residence. Using the geographical coordinates of the participants' home residences, a 500 m proxy for exposure to UGS was built. Annual average daily traffic (AADT) was estimated for all types of roads 100 m near the children's residence. Odds ratios (ORs) and 95% confidence intervals (95% CIs), UGS, traffic exposure, and their possible interactions were calculated for overall childhood leukaemia, and the acute lymphoblastic (ALL) and acute myeloblastic leukaemia (AML) subtypes, with adjustment for socio-demographic covariates. RESULTS: We found an increment of childhood leukaemia incidence related to traffic exposure, for every 100 AADT increase the incidence raised 1.1% (95% CI: 0.58-1.61%). UGS exposure showed an incidence reduction for the highest exposure level, Q5 (OR = 0.63; 95% CI = 0.54-0.72). Regression models with both traffic exposure and UGS exposure variables showed similar results but the interaction was not significant. CONCLUSIONS: Despite their opposite effects on childhood leukaemia incidence individually, our results do not suggest a possible interaction between both exposures. This is the first study about the interaction of these two environmental factors; consequently, it is necessary to continue taking into account more individualized data and other possible environmental risk factors involved.

Subjective well-being, happiness, and environmental health factors related to women planning a pregnancy or pregnant, using mobile health intervention.

Objectives: To compare the environmental health results in women trying to get pregnant or pregnant using a mobile health application (Green Page) through healthcare professionals or self-completed by women, and to explore the relationship between the subjective well-being of these women with their lifestyles and environmental factors. Methods: A descriptive study with mixed methods was conducted in 2018. A mobile health survey was used in two phases. Phase 1 was a cross-sectional study through professionals (n = 1100) followed by phase 2, a convenience sampling through women's self-reporting (n = 3425). A personalized report was downloadable with health recommendations for the well-being of the mother and child. Results: Of the 3205 participants (mean age = 33 years, SD = 0.2 years), 1840 were planning a pregnancy and 1365 were pregnant. One in five pregnant women had a low level of happiness. Globally, subjective well-being and happiness were found to be negatively associated with lack of contact with nature, sedentary lifestyle, excess weight, environmental exposure, and older age in pregnancy. Precisely 45%, 60%, and 14% of women were exposed to tobacco, alcohol, and illegal drugs, respectively. The women self-reported levels of risk factors higher than when the tool was used by or through professionals. Conclusions: The use of mobile health interventions focused on environmental health during planning or pregnancy periods could help improve the quality of healthcare and foster greater involvement of women in their self-care process, thus promoting empowerment, healthier environments, and lifestyles. Ensuring equity of access and data protection are global challenges to be addressed.

Breastfeeding and metabolic indicators in Mexican premature newborns.

BACKGROUND: Morbidity and mortality rates are higher among preterm infants due to physiological immaturity and greater growth demands. Nutritional intervention contributes to proper weight gain, which translates into better growth and neurological development, and prevents the onset of metabolic complications. The effect of breastfeeding duration was studied in the analytic profile at the end of the first six months of life. OBJECTIVE: To describe the nutritional and metabolic markers effect in preterm infants at the end of the first semester of life. MATERIAL AND METHODS: We performed an analytical, transversal and comparative study in 100 preterm infants, 30 to 36 weeks gestational age. Measures for weight, length and head circumference at birth were taken from the subjects' clinical files. A follow-up conducted at 6 to 9 months of age evaluated the same nutritional indicators (weight, length, head circumference) and compared them with values at birth and recommendations. Metabolic indicators (glucose, hemoglobin, cholesterol, triglycerides, insulin, urea, creatinine, gamma-glutamyl-transferase and alkaline phosphatase) were compared with the recommendations. Follow-up study in 100 preterm infants (30 to 36 weeks gestational age). Weight, length and head circumference were measured at birth and 6 to 9 months later. We measured analytic parameters related to metabolic syndrome (glucose, hemoglobin, cholesterol, triglycerides, insulin, urea, creatinine, gamma-glutamyl transferase and alkaline phosphatase). Confusing factors like income level and access to public services were also studied. RESULTS: The mean age at follow-up was 7.3 +/- 1.4 months. Levels of hemoglobin, creatinine and urea showed significant differences with regard to reference values (Wilcoxon ranks test, < 0.05). The average duration of breastfeeding was 4.3 months. The mean age at follow-up was 7.3 +/- 1.4 months. Risk factors for hypercholesterolemia, as well as levels of hemoglobin, creatinine and urea showed significant differences with regard to reference values (Wilcoxon ranks test, < 0.05). CONCLUSIONS: Premature infants showed deficiencies in weight gain. Biochemical parameters could reflect metabolic risk, therefore we recommend prolonging breastfeeding as well as extending the follow-up of these infants for monitoring their growth and development once out of the hospital.

[Occupational exposures, diet and storing: Recommendations to reduce environmental pollutants in breastfeeding]. / Exposiciones laborales, dieta y envasado: recomendaciones para reducir los contaminantes medioambientales en la lactancia materna.

The pollution of the planet also reaches the breastfeeding ecosystem, one of the most intimate and inviolable that links us as an animal species to the rest of mammals. Nursing mothers may be concerned about whether the quality of their milk will be adequate for their baby and whether environmental pollutants through work, diet, and storing may adversely affect their child. Breast milk is a source of exposure to environmental pollutants, and at the same time it counteracts much of the effects of these exposures. An approach based on the principles of reality and precaution of environmental health to avoid, reduce or eliminate the production and use of harmful chemicals during pregnancy and lactation would improve the human and planetary health for the offspring.

Case control study of periconceptional folic acid intake and nervous system tumors in children.

PURPOSE: Since 1992, the Centers for Disease Control and Prevention recommends that women of childbearing age consume 400 µg of folic acid per day to reduce the risk of neural tube defects (NTD). It has been speculated that both NTD and nervous system tumors (NST) may share common mechanisms of altered development. It examines the association between folic acid supplementation and the risk for childhood NST. METHODS: Incident cases of children with cancer in Spain registered between 2004 and 2006 were identified through the MACAPE Network Group. Tumors were classified as tumors derived from the neuroectoderm (cases) and those with a mesoderm origin (controls). In a second analysis, NST were further divided into central nervous system tumors (CNST) and sympathetic nervous system tumors (SNST). We compared folic acid supplementation between the groups. RESULTS: Overall, folic acid supplementation any time during pregnancy was similar between cases and controls (odds ratio (OR)=1.05; 95% confidence interval (CI) 0.92-1.20). However, supplementation before the 21st and 36th days of gestation resulted in significantly lower NST than in children with mesoderm tumors (OR=0.34; 95% CI 0.17-0.69 and OR=0.58; 95% CI 0.37-0.91, respectively). Preconceptional intakes of folic acid were also lower in NST although marginally nonsignificant (OR=0.44; 95% CI 0.10-1.02). When NST were divided into CNST and SNST, significant differences between tumors of mesoderm origin were only found for CNST. CONCLUSIONS: Our results support the hypothesis that folate supplementation reduces the risk of childhood NST, especially CNST. The specific mechanism and cellular role that folate may play in the development of CNST have yet to be elucidated.

[Urban air pollution and hospital admissions for asthma and acute respiratory disease in Murcia city (Spain)]. / Contaminación atmosférica urbana e ingresos hospitalarios por asma y enfermedades respiratorias agudas en la ciudad de Murcia (España).

INTRODUCTION: Urban air pollution is a major threat to child and adolescent health. Children are more vulnerable to its effects, being associated with higher morbidity and mortality due to acute and chronic diseases, especially respiratory ones. A study is performed on the relationship between urban air pollution and the rate of hospital admissions due to acute respiratory diseases. PATIENTS AND METHODS: An ecological study was conducted on young people under 17 years-old in the city of Murcia, who had visited hospital emergency departments due to respiratory diseases (ICD-9) during 2015. A logistic regression was performed on the risk of hospital admission that included consultations in relation to the average daily levels of environmental pollutants (NO2, O3, PM10, SO2) obtained from the Air Quality Surveillance and Control network of the Region of Murcia. Other control variables, such as gender, age, average daily ambient temperature, and season of the year. RESULTS: A total of 12,354 (56% boys and 44% girls) children consulted in the emergency department for respiratory disease. Of those, 3.5% were admitted, with a mean age of 2.54 (95% CI; 2.16-2.91) years. The odds ratio (OR) of hospital admission for respiratory diseases: NO2 1.02 (95% CI; 1.01-1.04; P<.01), O3 1.01 (95% CI; 1.00-1.03; P<.01) male 1.4 (95% CI 1.11-1.79; P<.01) and winter 2.10 (95% CI 1.40-3.21; P<.01). Admissions for asthma: PM10 1.02 (95% CI; 1.01-1.04; P<.05), O3 1.04 (95% CI; 1.01-1.06; P<.01). Admissions for bronchiolitis: Age 0.69 (95% CI; 0.48-0.99; P<.05); NO2 1.03 (95% CI; 1.01-1.05; P<.01). CONCLUSIONS: Urban air pollution increases hospital admissions in children due to acute respiratory diseases, especially asthma and bronchiolitis. Implementing preventive measures, expanding time series and collaborative studies with open data, would help improve public health and air quality in the cities.

Pediatric acute lymphoblastic leukemia and exposure to pesticides.

Organophosphates are pesticides ubiquitous in the environment and have been hypothesized as one of the risk factors for acute lymphoblastic leukemia (ALL). In this study, we evaluated the associations of pesticide exposure in a residential environment with the risk for pediatric ALL. This is a case-control study of children newly diagnosed with ALL, and their mothers (n = 41 child-mother pairs) recruited from Georgetown University Medical Center and Children's National Medical Center in Washington, DC, between January 2005 and January 2008. Cases and controls were matched for age, sex, and county of residence. Environmental exposures were determined by questionnaire and by urinalysis of pesticide metabolites using isotope dilution gas chromatography-high-resolution mass spectrometry. We found that more case mothers (33%) than controls (14%) reported using insecticides in the home (P < 0.02). Other environmental exposures to toxic substances were not significantly associated with the risk of ALL. Pesticide levels were higher in cases than in controls (P < 0.05). Statistically significant differences were found between children with ALL and controls for the organophosphate metabolites diethylthiophosphate (P < 0.03) and diethyldithiophosphate (P < 0.05). The association of ALL risk with pesticide exposure merits further studies to confirm the association.

Estimated intake levels of methylmercury in children, childbearing age and pregnant women in a Mediterranean region, Murcia, Spain.

Methylmercury (MeHg) is a bioaccumulable toxin in the trophic chain and a powerful neurotoxin during fetal and child development. Consumption of contaminated fish and shellfish is a principal environmental source of MeHg exposure. This study was designed to assess the Hg and estimated MeHg intake in vulnerable groups of the Murcia region, a Mediterranean part of Spain, compared with international regulations. A validated food frequency questionnaire was used to assess seafood consumptions in 320 children younger than 10 years, 301 women of childbearing age, and 537 pregnant women. Hg concentrations were measured in the most consumed fish products by cold vapor generation-atomic fluorescence spectrometry. The weekly intake of MeHg (microg/kg bw/week) was 2.60 (95% CI = 2.10-3.10) in children 1-5 years, 2.65 (95% CI = 2.26-3.03) in children 6-10 years, 0.98 (95% CI = 0.89-1.07) in women of childbearing age, and 0.88 (95% CI = 0.81-0.95) in pregnant women. The main exposure to MeHg, especially in young children, is related to intake of bluefin tuna and swordfish. Fifty-four percent of children aged 1-10 years, 10% of pregnant women, and 15% of women of childbearing age exceed the Joint Expert Committee on Food Additives provisional tolerable weekly intake of MeHg. In the Murcia region, where fish is a central component of the diet, the focus should be on educating vulnerable populations to reorient fish consumption in order to lower the amount of Hg incorporated with the diet as well as to reduce Hg emissions into the environment.

Sociocultural aspects of drug dependency during early pregnancy and considerations for screening: Case studies of social networks and structural violence.

OBJECTIVE: To contribute in closing the current gap in literature that holistically examines sociocultural influences on perinatal drug dependency. This article draws from social network theory and structural violence to qualitatively consider the contextual components of addiction and substance use during pregnancy, which purposefully moves away from situating this issue from solely being within the contexts of pathologized disorders or products of social inequalities. DESIGN: Face-to-face semi-structured interviews with drug-dependent pregnant women identified during a reproductive environmental health consultation. SETTING: Interviews were conducted at a university hospital in southeastern Spain between October 2015 and June 2016. PARTICIPANTS: 10 pregnant women with confirmed perinatal substance use and/or drug dependency. FINDINGS: The sociocultural perspective offers a useful lens by which providers can understand the reasons for initial substance use and progress of multi-drug dependency as way of individually tailoring intervention strategies for expecting mothers. This perspective draws from the frameworks of social network analysis (SNA) and structural violence to dialectically examine drug dependency in this unique patient population not to be solely an individual occurrence, but rather a combination of macro and micro-level factors at play. KEY CONCLUSIONS: The sociocultural approach in examining maternal health allows for the holistic exploration of the already taboo and symbolically paradoxical phenomenon of drug dependency in pregnant women. IMPLICATIONS FOR PRACTICE: The "Hoja Verde" and similar perinatal screening methods that comprehensively assess for the potential of environmental risks can be a key instrument in the practice of preventing developmental issues of children as early as pregnancy and into adolescence.

[Threats, challenges and opportunities for paediatric environmental health in Europe, Latin America and the Caribbean]. / Amenazas, desafíos y oportunidades para la salud medioambiental pediátrica en Europa, América Latina y el Caribe.

In a world that is increasingly technological and interconnected, but also more violent, overexploited and polluted, Paediatric Environmental Health (PEH) is one of the best contributions to improve global health. Few areas of the planet have a high affinity with common values and interests, such as the European Union (EU), Latin America and the Caribbean (LAC). The investments and actions of the PEH in pre- and postnatal periods during the first two decades of life will generate countless benefits in the health and well-being during the human life span. Detecting, reducing, or eliminating physical, chemical, biological and social pollutants is one of the main missions and actions of the PEH. In this special article, an update review is presented on the threats, challenges and cooperation opportunities in PEH among bio-health professionals and other social sectors involved, from the EU and LAC. New professional profiles, knowledge structures and architectures for engagement emerge. Courageous leaderships, new substantial resources, broad social changes, and the necessary collaboration between the two regions will be required to improve the health of present and future generations.

Full Breastfeeding and Obesity in Children: A Prospective Study from Birth to 6 Years.

BACKGROUND: Obesity is a major public health crisis among both children and adults and contributes to significant physical, psychological, and economic burden. We aim to investigate the effect of duration of breastfeeding on excessive weight and obesity at 6 years of age. SUBJECTS/METHODS: Data on breastfeeding and child anthropometric measurements were collected in a birth-cohort study in Murcia, Spain (n = 350). Breastfeeding status and body mass index (BMI) were established according to WHO definitions. Other factors potentially related to children's weight were considered. Multiple log-linear and ordinal regressions were used to analyze the effects of breastfeeding on overweight and obesity when considering potential confounders. RESULTS: 33% and 17.3% of children in the study were of excess weight and obesity, respectively. Univariate predictors of BMI in children aged 6 were as follows: pregestational maternal BMI (kg/m2) (R2 = 0.127, p < 0.01); full breastfeeding (weeks) R2 = -0.035, p < 0.01); infant weight gain (kg) (R2 = 0.348, p < 0.01); and maternal alcohol consumption during pregnancy (g/day) (R2 = 0.266, p < 0.01) at age 6. In the ordinal logistic regression, full breastfeeding was associated with a significant decrease in obesity -0.052 (95% CI, -0.10 to -0.003). CONCLUSIONS: The delay of bottle feeding introduction may have a protective effect against obesity at 6 years of age. Our findings reinforce the need for greater support of breastfeeding and to promote a healthy environment and antipoverty interventions during pregnancy and infancy, alongside other strategies for obesity prevention.

Paediatric environmental health speciality units in Europe: integrating a missing element into medical care.

Paediatricians are in an excellent position to identify children with environmental risk, to advise their parents about the best way of reducing or preventing such risks, and to recommend actions to the responsible politicians involved. Paediatric environmental health speciality units (PEHSU) can help to qualify and support paediatricians in this task. PEHSU is defined as a unit within a paediatric hospital or clinic that is able to recognize, assess, and prevent environment-related health risks, to help other paediatric specialists in the management of such diseases in children, as well as to provide education, training, and research, putting emphasis on thorough and adequate establishment of paediatric environmental histories (PEHis) and to the application of the precautionary principle. Although activities and services provided by each PEHSU would differ depending on the centre or community where it is located, all should include training, research, medical care and community and school health.
