Pollen exposure during pregnancy ups offspring’s asthma risk

Wednesday, January 9th, 2013

Exposure to high pollen levels in late pregnancy significantly increases the risk of early asthma in the child, Swedish researchers have warned.

A number of studies have previously shown that there is an association with being born during a pollen season and an increased risk of allergies.

Although the pollen season is a regular annual event, there are large variations between years in pollen levels.

Few studies have closely examined the significance of actual pollen content in different time periods before and after birth, but now, researchers at the Division of Occupational and Environmental Medicine at Umeå University have conducted such a study involving 110,000 pregnancies in the Stockholm area.

The researchers note that high levels of pollen exposure during the last 12 weeks of pregnancy resulted in a significantly increased risk of hospitalization for asthma symptoms in the first year of life for a child. The analysis was adjusted for factors such as maternal smoking and pollen season.

DNA, not just fast food, to be blamed for obesity

Wednesday, January 9th, 2013

It’s not just what you eat that makes those pants tighter — it’s also genetics, researchers have claimed.

In a new study, scientists discovered that body-fat responses to a typical fast-food diet are determined in large part by genetic factors, and they have identified several genes they say may control those responses.

The study is the first of its kind to detail metabolic responses to a high-fat, high-sugar diet in a large and diverse mouse population under defined environmental conditions, modeling closely what is likely to occur in human populations.

The researchers found that the amount of food consumed contributed only modestly to the degree of obesity.

“Our research demonstrates that body-fat responses to high-fat, high-sugar diets have a very strong genetic component, and we have identified several genetic factors potentially regulating these responses,” first author Dr. Brian Parks, a postdoctoral researcher at the David Geffen School of Medicine at UCLA said.

Too much diet soda and sweetened drinks could lead to depression

Wednesday, January 9th, 2013

Drinking sweetened beverages, especially diet drinks, is associated with an increased risk of depression in adults while drinking coffee is tied to a slightly lower risk, new research suggests.

“Sweetened beverages, coffee and tea are commonly consumed worldwide and have important physical—and may have important mental—health consequences,” study author Honglei Chen, MD, PhD, with the National Institutes of Health in Research Triangle Park in North Carolina and a member of the American Academy of Neurology said.

The study involved 263,925 people between the ages of 50 and 71 at enrollment.

From 1995 to 1996, consumption of drinks such as soda, tea, fruit punch and coffee was evaluated.

About 10 years later, researchers asked the participants whether they had been diagnosed with depression since the year 2000. A total of 11,311 depression diagnoses were made.

Host of health problems caused by not changing bedsheets once a month

Wednesday, January 9th, 2013

Nearly a fifth of people in the UK fail to change their bed sheets at least one a month, which could result in them suffering from a host of health woes ranging from asthma to rhinitis and eczema, according to new figures.

The research, commissioned for the home retailer Dunelm Mill, found that more than 50 percent people slept in dirty sheets.

The survey of more than 2,000 people found that just two in five people changed their sheets weekly, the Daily Mail reported.

A further 36 percent performed the task fortnightly, while 17 percent admitted that they changed their dirty sheets just once a month or even less frequently.

Meanwhile, six percent of people admitted to changing the sheets more than once a week, one percent of people admitted that they changed it just once a year, while three percent had no idea.
