Open Parachute

 Here are the rankings of New Zealand blogs with publicly available statistics for May 2017. There are about 300 blogs on the list, although I am weeding out those which are no longer active or have removed public access to sitemeters. (Let me know if I weed out yours by mistake or get your stats wrong). Every month I get queries from people … Read More

Anti-fluoride activists tell porkies about the Ministry of Health’s data on child dental health. They cherry-pick the data to make it appear that community water fluoridation is ineffective. And when challenged to discuss the issue they run away. I am currently dealing with family issues so am reposting this article, “A challenge to anti-fluoridationers to justify their misrepresentation of New … Read More

Local antifluoride activists are busy presenting ChildSmile and similar programmes as alternatives to fluoridation. They aren’t – and New Zealand District health Boards already operate elements of these programmes where they consider them effective. I am currently dealing with family issues so am reposting this article, “ChildSmile dental health – its pros and cons” from September 2015.   There is … Read More

Recent research reveals that community water fluoridation benefits adults as well as children. While research into the effects of fluoridation in adults started earlier than for children, early studies suffered from a lack of information on effects of socioeconomic status and other confounding factors.  Recent studies with adults have been more robust but there is still some confusion – especially since … Read More

Anti-fluoride activists going on about contaminants in drinking water due to fluoridation have it all wrong. If they avoided their knee-jerk, chemophobic reactions to certificates of analysis and did some calculations they would realise they are making a fuss about absolutely nothing. I am currently absorbed in dealing with family issues at the moment so am reposting this article, “Chemophobic … Read More

Today and tomorrow we remember the end of the war in Europe 72 years ago. I think this video provides a fitting illustration of what that war meant to nations and families around the world – and why we commemorate its end. It’s also an excellent example of what can be done with data visualisation. I don’t think I have seen a better … Read More

New recommended fluoride dietary intakes by infants and young children in Australia and New Zealand were recently published. The updated values are available online at Nutrient Reference Values for Australia and New Zealand. This is a regular update – the Australian National Health and Medical research council advises these recommendations be reviewed every 5 years. But the new recommendations are interesting because … Read More

One thing that gets me going (as readers here probably know) is the way scientific citations are cherry-picked and dragged in to support biased positions. It’s a common form of confirmation bias in the fluoridation debate. And I get even angrier when the perpetrators cherry-picking citations will then claim they “have science on their side.” Parroting citations and (often unconnected) claims … Read More

This last week has certainly raised the profile of the “science debate” in New Zealand. Most importantly we saw big turnouts for the Science March in several major cities – a demonstration that lots of scientists and supporters of science feel that science could be threatened – or at least that it is unappreciated by the politicians and other decision-makers. Maybe … Read More
