Childhood Obesity Linked To Air Pollution From Vehicles (theguardian.com) 166

Early exposure to air pollution from vehicles increases the risk of children becoming obese, new research has found. From a report: High levels of nitrogen dioxide, which is emitted by diesel engines, in the first year of life led to significantly faster weight gain later, the scientists found. Other pollutants produced by road traffic have also been linked to obesity in children by recent studies. Nitrogen dioxide pollution is at illegal levels in most urban areas in the UK and the government has lost three times in the high court over the inadequacy of its plans. The pollutant also plagues many cities in Europe and around the world. "We would urge parents to be mindful where their young children spend their time, especially considering if those areas are near major roads," said Jeniffer Kim, at the University of Southern California, who led the new research. "The first year of life is a period of rapid development of various systems in the body [and] may prime the body's future development." The World Health Organization (WHO) revealed last Monday that 90% of the world's children are breathing unsafe air, a situation described as "inexcusable" by the WHO's head. Concern over the impact of toxic air on children's health is rising as research reveals serious long-term damage to both their physical and mental health.

          Personal accountability is one of those things that tends to affect a shitload of things in your life, both good and bad. And obesity is overwhelmingly attributed to personal decisions, so my theory is hardly delusional. No it's not "always" that. In this case, it's about 95% that.

          That said, perhaps we should look at TFA to see what kind of crisis this actually is:

        I was under the distinct impression that sunspots where unexpectedly low in number. Not a Maunder Minimum, but it has been very disruptive to HF radio propagation as a lack of sunspots thins out the ionosphere and drives the MUF (Maximum Usable Frequency) down. The lower bands are *really* impacted by impulse noise (lighting, arching and other very loud RF sources) and for ham radio operators stuffs a lot of us in very small and narrow portions of the 75 and 40 meter bands.

    • It is also not hard to think of likely causal connections either: areas with high air pollution are either likely to be poorer and/or have more traffic which will mean less playing outside and fewer trips to the grocery store making processed foods with longer shelf lives more appealing than fresh produce. I wish journals would remember that correlation != causation and refuse to publish crap like this without actual evidence of cause.

        They do. Catalytic converters specifically target nitrogen oxides, and NO2 levels have fallen dramatically [epa.gov] over the last 20 years.

        Has there been a corresponding decrease in childhood obesity? No.

        To be fair, older cars produce much more NO2 than newer models, so kids in low income neighborhoods are more likely to have higher NO2 exposure, and are more likely to be obese. But even in low income areas, NO2 levels have fallen, with no corresponding decrease in childhood obesity.

      Really though, you don't need extensive exercise to lose weight, just better eating habits. I dropped 30 lbs. a few years back just by cutting out unnecessary snack foods and other crap without doing additional high-intensity exercise. It's much easier not to put an additional 600 calories into your body than it is to burn that 600 calories (on top of what you already do) off later.

        That is easy: the diesel engines that smoke heavily burn at low temperatures, leaving lots of unburned carbon. The oxides of nitrogen are produced by burning the nitrogen in the air, not diesel. This only became a problem after diesel engines were modified to run hotter reduce the carbon dioxide. To create lots of oxides of nitrogen, the engines have to run seri
