Laura Birks, Mònica Guxens, Eleni Papadopoulou, Jan Alexander, Ferran Ballester, Marisa Estarlich, Mara Gallastegi, Mina Ha, Margaretha Haugen, Anke Huss, Leeka Kheifets et al. Maternal cell phone use during pregnancy and child behavioral problems in five birth cohorts. Environment International. Published online April 7, 2017.
http://doi.org/10.1016/j.envint.2017.03.024

"This is the largest study to date to evaluate these associations and to show mostly consistent results
across cohorts with retrospectively and prospectively assessed maternal cell phone use."

Highlights

• Largest study to date to use prenatal cell phone use data collected prospectively.
• High prenatal cell phone use linked to hyperactivity/inattention problems in child.
• No prenatal cell phone use linked to low risk for any behavioral problems in child.
• Analysis adjusted for many confounders, but associations cannot be judged causal.
• Future research should adjust for parenting style, maternal hyperactivity, and more.

Introduction Previous studies have reported associations between prenatal cell phone use and child behavioral problems, but findings have been inconsistent and based on retrospective assessment of cell phone use. This study aimed to assess this association in a multi-national analysis, using data from three cohorts with prospective data on prenatal cell phone use, together with previously published data from two cohorts with retrospectively collected cell phone use data.

Methods We used individual participant data from 83,884 mother-child pairs in the five cohorts from Denmark (1996–2002), Korea (2006–2011), the Netherlands (2003–2004), Norway (2004–2008), and Spain (2003–2008). We categorized cell phone use into none, low, medium, and high, based on frequency of calls during pregnancy reported by the mothers. Child behavioral problems (reported by mothers using the Strengths and Difficulties Questionnaire or Child Behavior Checklist) were classified in the borderline/clinical and clinical ranges using validated cut-offs in children aged 5–7 years. Cohort specific risk estimates were meta-analyzed.

Results Overall, 38.8% of mothers, mostly from the Danish cohort, reported no cell phone use during pregnancy and these mothers were less likely to have a child with overall behavioral, hyperactivity/inattention or emotional problems. Evidence for a trend of increasing risk of child behavioral problems through the maternal cell phone use categories was observed for hyperactivity/inattention problems (OR for problems in the clinical range: 1.11, 95% CI 1.01, 1.22; 1.28, 95% CI 1.12, 1.48, among children of medium and high users, respectively). This association was fairly consistent across cohorts and between cohorts with retrospectively and prospectively collected cell phone use data.

Conclusions Maternal cell phone use during pregnancy may be associated with an increased risk for behavioral problems, particularly hyperactivity/inattention problems, in the offspring. The interpretation of these results is unclear as uncontrolled confounding may influence both maternal cell phone use and child behavioral problems.

Effects of prenatal exposure to WiFi signal on postnatal development and behavior in rat: Influence of maternal restraint

Haifa Othman, Mohamed Ammari, Mohsen Sakly, Hafedh Abdelmelek. Effects of prenatal exposure to WiFi signal (2.45 GHz) on postnatal development and behavior in rat: Influence of maternal restraint. Behavioural Brain Research. 36:291-302. May 2017. http://dx.doi.org/10.1016/j.bbr.2017.03.011

Highlights

• Effects of gestational exposure to WiFi signal and restraint along gestation period on the offspring were studied.
• The pups were evaluated for physical development and neuromotor maturation.
• Gestational WiFi exposure and restraint, adversely affected offspring neurodevelopment and behavior at adulthood.
• Progeny brain oxidative balance and serum biochemistry were disrupted.

Abstract

The present study was carried out to investigate the potential combined influence of maternal restraint stress and 2.45 GHz WiFi signal exposure on postnatal development and behavior in the offspring of exposed rats. 24 pregnant albino Wistar rats were randomly assigned to four groups: Control, WiFi-exposed, restrained and both WiFi-exposed and restrained groups. Each of WiFi exposure and restraint occurred 2 h/day along gestation till parturition. The pups were evaluated for physical development and neuromotor maturation. Moreover, elevated plus maze test, open field activity and stationary beam test were also determined on postnatal days 28, 30 and 31, respectively. After behavioral tests, the rats were anesthetized and their brains were removed for biochemical analysis. Our main findings showed no detrimental effects on gestation progress and outcomes at delivery in all groups. Subsequently, WiFi and restraint, per se and mainly in concertaltered physical development of pups with slight differences between genders. Behaviorally, the gestational WiFi irradiation, restraint and especially the associated treatment affected the neuromotor maturation mainly in male progeny. At adult age, we noticed anxiety, motor deficit and exploratory behavior impairment in male offspring co-exposed to WiFi radiation and restraint, and in female progeny subjected to three treatments. The biochemical investigation showed that, all three treatments produced global oxidative stress in brain of both sexes. As for serum biochemistry, phosphorus, magnesium, glucose, triglycerides and calcium levels were disrupted. Taken together, prenatal WiFi radiation and restraint, alone and combined, provoked several behavioral and biochemical impairments at both juvenile and adult age of the offspring.

Is electromagnetism one of the causes of Colony Collapse Disorder? A work plan for testing this hypothesis

Abstract

The decline of domestic bees all over the world is an important problem still not well understood by scientists and beekeepers, and far from being solved. Its reasons are numerous: among others, the use of pesticides and insecticides, the decrease of plant diversity, and bee’s parasites. Besides these threats, there is a potential adverse factor little considered: manmade electromagnetism. The production of electromagnetic waves by human settlements, cellphones relay and power lines largely increases nowadays. Bees are very sensitive to this electromagnetism. The present paper suggests two simple experimental protocols for bringing to the fore the potential adverse effect of electromagnetism on bees and to act consequently. The first one is the observation of bees’ avoidance of a wireless apparatus; the second one is the assessment of colonies’ strength and of the intensity of the electromagnetism field (EMF) surrounding them. If bees avoid a wireless apparatus, if hives in bad health are located in EMF of a rather high intensity, it can be presumed that bees are affected by manmade electromagnetism. This should enable searching for palliative measures.
