A study of 52 adults in Obesity found late sleepers slept less, ate more at dinner and after 8 p.m., and had higher BMI. A separate Pediatrics study of 308 children reported obese children slept less and more variably on weekends, alongside adverse metabolic markers.

Autism estimates could increase worldwide
Researchers screening 55,000 South Korean children aged 7 to 12 found 1 in 38 had an autism spectrum disorder, and more than two-thirds of cases in mainstream schools went unrecognised and untreated. They say careful population screening may raise prevalence estimates worldwide.

May is High Blood Pressure Education Month
Nearly 68 million Americans have high blood pressure and 28% of adults have prehypertension, which often progresses to hypertension. The piece sets out the thresholds: normal under 120/80, prehypertension 120-139 or 80-89, and high blood pressure 140/90 or above.

Do toddlers with autism have bigger brains by age 2?
MRI scans of 59 children with autism spectrum disorder and 38 controls showed generalized cortical enlargement at age 2, with disproportionately large temporal lobe white matter. Growth from ages 2 to 4 matched controls, pointing to faster growth before age 2.

More Americans Living with Asthma Every Year
A CDC Vital Signs report counts about 25 million Americans, 8 percent of the population, with asthma in 2009, up 4.3 million since 2001. Costs rose from about $53 billion in 2002 to $56 billion in 2007, and 40 percent of uninsured people with asthma could not afford their medicine.

Prevalence of Obesity Among Adults with Arthritis
CDC's analysis of 2003-2009 survey data found obesity prevalence among adults with doctor-diagnosed arthritis averaged 54 percent higher than among adults without arthritis, ranging in 2009 from 26.9 percent in Colorado to 43.5 percent in Louisiana.

Can your brain fall asleep while you're awake?
Rats kept awake showed problem-solving brain regions slipping into a kind of 'local sleep' while overall brain activity and behavior looked fully awake, and the animals struggled with hard tasks, a Nature study found. Researchers say the same is likely in sleep-deprived people.

May 3 - the National Mental Health Day
The American Academy of Pediatrics and SAMHSA mark National Children's Mental Health Awareness Day, focused this year on resilience in young children after disasters, family separation or violence. A CDC report found Massachusetts students involved in bullying more often report violence at home.

What diseases are killing the world?
WHO's first global status report on noncommunicable diseases found they caused 63 percent of deaths in 2008, or 36.1 million people: 17 million from cardiovascular disease, 7.6 million from cancer, 4.2 million from respiratory disease and 1.3 million from diabetes.

Obesity and arthritis link
CDC data from 2003 to 2009 show obesity was 54 percent more common among adults with arthritis than among those without, with state rates running from 26.9 percent in Colorado to 43.5 percent in Louisiana. Either condition can limit the activity that helps manage both.

This Devastating Mistake Can Wreck Your Immune System...
Mercola cites a Swedish study reporting roughly a 400 percent increased risk of narcolepsy in children and adolescents vaccinated with Pandemrix, echoing a Finnish finding, and argues that serious vaccine reactions are too readily dismissed as coincidence.

Diagnosing autism at the 1-year well-baby check-up
Pediatricians screened 10,479 one-year-olds with a communication and behaviour checklist. Of 184 who failed and were evaluated, 32 received a provisional or final autism diagnosis, 56 language delay and nine developmental delay; positive predictive value was estimated at .75.

JAMA study reports on fatty liver disease in children and teens (PR)
In a 10-site randomized trial, neither vitamin E nor metformin reduced liver enzymes in children and teens with nonalcoholic fatty liver disease. Biopsies did show an improved injury pattern with vitamin E in patients with a severe form of the disease.

Melatonin might help in controlling weight gain (PR)
University of Granada researchers report that melatonin helped young Zucker diabetic obese rats limit weight gain without eating less, cut triglycerides and LDL and raise HDL. They say the finding would need confirmation in humans.
Disease
Protect Yourself from MRSA
MRSA resists beta-lactam antibiotics and spreads in hospitals mainly on hands, especially staff hands. CDC advises asking doctors, nurses and visitors to clean their hands, asking how long catheters or drainage tubes must stay in, and learning wound care before going home.

Lyme disease prevention and tick awareness
Adult deer ticks are active across the Northeast, mid-Atlantic and upper Midwest, and about half carry a pathogen such as the Lyme bacterium, the URI TickEncounter Resource Center says. The piece lists CDC symptoms and gives step-by-step tweezers removal instructions.

How Supermodel Gisele Bundchen "Infuriated Cancer Experts"...
The Environmental Working Group's annual report claims nearly half of 500 popular sunscreens may speed the development of skin cancer cells because they contain retinol and retinyl palmitate, and that the FDA has sat on a decade-old study. Gisele Bundchen separately called sunscreen poison.

ADHD linked to premature birth
Swedish researchers who looked at more than 1 million people aged 16 to 19 found those born at 23 to 28 weeks were about two and a half times as likely to later get an ADHD prescription as those born at term: 15 per 1,000 against 6 per 1,000.
