University of Waterloo Research Chair wind turbine study results statistically significant

Health_studies_before_WTOct. 24.2013/ At a recent symposium in Toronto facilitated by former Toronto Mayor David Miller titled Symposia of the Ontario Research Chairs in Public Policy, a Poster entitled ‘Wind Turbine Noise, Sleep Quality, and Symptoms of Inner Ear Problems’ was displayed by Claire Paller, Phil Bigelow, Shannon Majowicz, Jane Law, and Tanya Christidis.

The research indicates statistically significant results for sleep, vertigo and tinnitus (excerpt):

“All relationships were found to be positive and statistically significant.”

The University of Waterloo – Ontario Ministry of Environment funded IWT health study was publicly displayed during the symposium on sustainability held at York University , Toronto on October 17, 2013.

It is reported that 396 surveys were included in the analysis (excerpts include):

“In total there were 412 surveys returned; 16 of these survey respondents did not provide their home address. Therefore, 396 surveys were included in the analysis.”

Of note is the acknowledgement that as the distance from the IWT increases, sleep improves:

“The relationship between ln(distance) (as a continuous variable) and mean Pittsburgh Sleep Quality Index (PSQI) was found to be statistically significant (P=0.0096) when controlling for age, gender and county. This relationship shows that as the distance increases (move further away from a wind turbine), PSQI decreases (i.e. sleep improves) in a logarithmic relationship. Multivariate analysis involved assessing distance to the nearest wind turbine as both distance and ln(distance). In all cases, ln(distance) resulted in improved model fit.”

In addition the authors state that the relationship between vertigo and tinnitus worsened for those living closer to IWTs:

“The relationship between vertigo and ln(distance) was statistically significant (P<0.001) when controlling for age, gender, and county. The relationship between tinnitus and ln(distance) approached statistical significance (P=0.0755). Both vertigo and tinnitus were worse among participants living closer to wind turbines.”

The conclusion states:

“In conclusion, relationships were found between ln(distance) and PSQI, ln(distance) and self-reported vertigo and ln(distance) and self-reported tinnitus. Study findings suggest that future research should focus on the effects of wind turbine noise on sleep disturbance and symptoms of inner ear problems.”

Counties and projects in the study include:

  • Bruce (Enbridge project);
  • Chatham-Kent (Raleigh);
  • Dufferin (Melancthon);
  • Elgin ( Erie Shores );
  • Essex (Comber):
  • Frontenac ( Wolfe Island );
  • Huron (Kingsbridge); and
  • Norfolk (Frogmore/Cultus/ClearCreek).

Based on this evidence, it is not clear what the next steps will be for the Ministry of Environment. However, based on these results, evidence gathered by other researchers in Ontario and elsewhere supports these statistically significant findings.

  1. Shut the turbines down IMMEDIATELY.
    Sleep deprivation causes much illness.
    Sleep deprivation is a result of low frequency noise.
    Low frequencies were used as means of torture during the war.
    Exposure to low frequencies cause Vibro Acoustic Disease.
    Those responsible for the ill treatment of the people of rural Ontario must be held accountable.

  2. So I guess that some here did participate.

    Enough that the relationships between disturbed sleep and other symptoms did come out.

    All I can can say is “Thank you” to those that did participate.

  3. When will enough of the necessary people ACTUALLY read these important revelations about the proximity and sleep deprivation=illness????? how many more innocent people and animals need to be tortured by these corrupt, inefficient, non recyclable weapons of mass destruction????STOP THE INSANITY.Period.

    • When you ask? When you slap the cuffs on mcGuinty and his gang and throw their sorry arses in jail. They will have all the time in the world….

  4. Developers and other interested parties will likely try to find fault with these rsults or ignore them?
    And when these results become known to the public the parperty values near IWTs will really drop.

  5. You would think that this would suffice in convincing the government to stop this nonsense. There is clearly a link that has to be explored.

  6. Exactly! Listened to CBC Ontario Today (noon hour call in show, Radio 1). It was about so-called “public-private” partnerships. Read, public pay, private profit.

    Well that is exactly what Turbines are. Except, there is no “public good”. At least two people called about Turbines. The host kept mentioning “public good”. Totally avoided the questions.

    Email CBC and complain.

    • Will do Richard! I’ve been watching CBC for a while.
      We protested outside their building with close to 1000, not a peep.
      I wrote a complaint to CBC and Scotiabank about the Dragon’s Den advertising wind turbines on their opening sequence. Scotiabank gave customer service all the way to their ombudsman office, not a peep from CBC.
      I was looking forward to the show today and missed it. I always listen to whether they include wind turbine comments. You are right, they are extremely dismissive.
      CBC is losing so much public support.
      On the plus side, Scotiabank must have listened, I can now watch Dragon’s Den again, the wind turbines are gone!!!
      Wind turbines are personal, that is what this current government and so many organizations are learning.

      • It is really too bad, because otherwise I love the CBC. I’m talking about Radio 1 here, not TV. The radio does so much to bring the country together, music, culture, Canadian and international news, documentary, etc. They are just MIA when it comes to the Turbine issue. It is just sad and frustrating to see this.

  7. Kevin O’Leary hates the way this stupid government does business. It doesn’t make sense. You can’t give money away and expect to prosper and we are all paying dearly for this friggin mess. I was surprised O’Leary even allowed them on the show opener. I cancelled my Shaw acct because they started advertising wind energy and have been told those ads seem to have stopped. Keep writing.

  8. Quite frankly, I think the Liberal Ontario government is perpetrating a form of abuse on the taxpayers of Ontario. Not only do we pay dearly for our electricity while the government practically gives it away to other provinces and countries, but those living close to IWTs suffer physically and financially. Our wildlife is subjected to habitat destruction and slaughter, our landscape is ruined by gigantic towers that can be seen for miles. When these monoliths age, what happens to them? They catch fire, they topple over…who removes them ? We’re going down a very scary path. It’s time to say…NO MORE!
