Dementia Cases Worldwide to Triple by 2050:
WHO

The number of dementia cases worldwide will more than triple by 2050,
according to a World Health Organization report released Wednesday.

Currently, 35.6 million people have dementia. WHO said that number is
expected to double to 66 million by 2030 and 115 million by 2050, the
Associated Press reported.

The U.N. agency also said the proportion of dementia cases in low- and
middle-income countries will rise to more than 70 percent as those nations
see big increases in their populations of older people.

The agency noted that only eight countries have national programs to
deal with dementia, and it recommended better support for caregivers, the
AP reported.

Neighborhood Features Influence Weight:
Study

Neighborhood characteristics such as grocery stores and parks have an
influence on children’s weight, a new study says.

U.S. researchers examined neighborhoods in King County, Wash., and San
Diego County, Calif., and rated them in terms of physical activity and
nutrition for children ages 6 to 11, ABC News reported.

A neighborhood received a high rating if it had good parks, ample
opportunities for children to walk to places such as libraries and stores,
and had numerous food stores that offered produce and healthy foods. A
neighborhood received a poor rating if it had few good food stores, a
large number of fast food restaurants, and offered children few
opportunities to walk or play in good parks.

“The biggest difference we found in rates of obesity were in the places
where the environment was good for both nutrition and physical activity,
the rates were less than 8 percent, but if the nutrition and physical
activity were not good, the rates went up to 16 percent,” said study
co-author Brian Saelens, a professor of pediatrics at Seattle Children’s
Research Institute, ABC News reported.

The study was one of series of related studies published this week in a
special issue of the American Journal of Preventive Medicine.

Toxins Found in ‘Non-Toxic’ Nail Polishes at
Calif. Salons

Many nail polishes used in salons and advertised as free of three toxic
chemicals actually have high levels of one or more of the chemicals,
California officials say.

The mislabeled nail products could harm thousands of employees and
customers of the more than 48,000 nail salons in the state, according to
the Department of Toxic Substances Control report released Tuesday, the
Associated Press reported.

Investigators analyzed 25 brands of nail products, including a number
that claimed to be free of the chemicals toluene, dibutyl phthalate (DBP)
and formaldehyde, the so-called “toxic three.” Exposure to large amounts
of the chemicals has been linked to developmental problems, asthma and
other illnesses.

Toluene was found in 10 of 12 products that claimed to be free of the
chemical, and four of the products had dangerously high levels of toluene.
Five of seven products that claimed to be free of the “toxic three”
actually had one or more of the chemicals in significant levels, the
AP reported.

A decision on possible legal action will be made by the state attorney
general’s office.
