California study links prenatal fluoride exposure to delayed Infant Motor Development

California fluoride study

A newly published Californian study has reported an association between fluoride exposure during pregnancy and poorer gross motor development in infants, adding to the growing body of research examining fluoride’s potential effects on early neurodevelopment.

Action group Fluoride Free NZ described how researchers tracked mothers’ total fluoride exposure during the third trimester of pregnancy and compared it with their children’s developmental progress at six, nine, 12 and 18 months. The study found a statistically significant association with reduced gross motor skills, including milestones such as rolling, sitting, crawling and walking. While no statistically significant links were identified for fine motor skills, communication, problem-solving or social development, the researchers said the results for fine motor and problem-solving abilities suggested a possible underlying pattern that warrants further investigation.



The authors said a key strength of the research was its prospective cohort design and its focus on measuring total fluoride exposure during late pregnancy, a period considered critical for brain development. They argued this approach provides a more accurate assessment than relying solely on fluoride concentrations in public drinking water, as overall exposure can also come from sources such as tea, seafood and some medications. The findings were said to align with previous studies from Canada, the United States and Mexico that have also examined total fluoride intake during pregnancy.

The study’s publication comes amid ongoing debate over water fluoridation and its health impacts. Critics of ecological studies, including a recently funded New Zealand project, argue such research is less capable of detecting potential associations because it does not account for individual fluoride exposure levels or the timing of exposure during pregnancy. The Californian researchers concluded that their findings, together with earlier studies, suggest fluoride exposure during gestation “may interfere with neurodevelopmental processes across multiple domains” even at relatively low exposure levels.

  1. I recall Luxon refused to remove fluoride from local council supply. Well well well, its election time again Luxon. Time for you take your medicine. Even if Luxon retains power, the margins will be thin. He will be rolled by his own party.

  2. The Corporate State must have a dumbed down compliant citizenry to fund its parasitical practice of wealth extraction and power consolidation, without killing them outright. The Corporate State/Corporate Agenda will poison the air,water,food and your body directly to achieve the Corporate owners agenda of owning it all, meaning the world and all in it.

  3. Heard a recent rumour that pfizer has told moh / health nz / mpi they are disappointed with the kill rate of their convid poison and flouride poison in the water is simply not helping to do the job well enough.
    Apparently now the recommendation is to “treat” all nz water supplies with cyanide at a few parts per million.
    It won’t kill everyone right away and, using the same lying strategy as the convid poison campaign, seed oils lies, poisonous mercury in vaccines and statins just to name but a few cons, can easily be successfully promoted as “LOW FAT”, so it has got to be good for you”!
    They have no doubt that many will believe as they have already proven that a seriously large proportion of the population is indeed stupid plus flouride has has obviously at least partly worked as people are evermore more docile, compliant and have proven lower IQ’s.
    No doubt why we get more and more morons aspiring to be politicians.

  4. This is why we use a Big Berkey gravity-filtered water system with the PF-2 filters that removes fluoride and radioactive isotopes!

  5. Perfect time for New Zealanders to force the fluoride issue onto the political parties vying for power this November. Personally I have lived in Thailand for the last ten years and only drink bottled water as tap water is untreated. I haven’t had any teeth problems during that time despite now being an old fart, unlike when I was living in NZ drinking fluoridated water.

  6. Well its pain in the ass but my family only drinks and cook with river, rain, natural spring or artesian water.

    Avoid plastic bottles and sunlight. Use glass or better still, Temu have 2 skin metal bottles of all sizes. Blocks sunlight and the double skin keeps it cool even in in direct sunlight.

    Below are the best-known public artesian water filling points in New Zealand, with official links where available.

    1. Te Puna Wai Ora (Petone, Lower Hutt)

    Location: Buick Street, Petone

    The most famous public artesian water tap in New Zealand. Water comes from the Waiwhetū Aquifer, is naturally filtered underground, then UV-treated before dispensing. There are taps for filling bottles and containers, and drinking fountains.

    2. Dowse Square Artesian Tap (Lower Hutt)

    Location: Laings Road, outside the Dowse Art Museum

    Another public filling station drawing from the Waiwhetū Aquifer. Less busy than Petone and suitable for filling large containers.

    3. Waiwhetū Artesian Tap (Lower Hutt)

    Location: Riverside Drive, Waiwhetū

    Opened in 2020 near Waiwhetū Marae. Like the other Hutt taps, the water comes from the Waiwhetū Aquifer, is naturally filtered underground and UV-treated before reaching the public taps.

    4. Christchurch Artesian Aquifer

    Christchurch is built over one of New Zealand’s largest artesian aquifer systems. Historically there were hundreds of artesian wells, but most public taps have been removed or converted as part of modern drinking-water management. Public filling locations are now very limited.

    5. Heretaunga Plains (Hawke’s Bay)

    The Heretaunga Plains contain a major confined aquifer with many artesian bores. Most are on private land or are municipal water supplies, so there are very few public filling points.

    6. Canterbury Plains

    Numerous farms have flowing artesian wells, but these are generally private and not available for public access.

    7. Southland

    Southland has several artesian aquifers, particularly around Invercargill, but public filling stations are uncommon.

    Summary

    If your goal is to fill drinking-water containers, the three Hutt Valley locations are the best-known and easiest public access points in New Zealand:

    Te Puna Wai Ora, Buick Street, Petone
    Dowse Square, Laings Road, Lower Hutt
    Waiwhetū, Riverside Drive, Lower Hutt

    All three draw from the same Waiwhetū Aquifer and are officially maintained by Hutt City Council.

    If you’re travelling by caravan, I can also compile a list of free natural springs and public artesian taps throughout both the North and South Islands, including lesser-known roadside springs used by locals.
