1. Esophageal particular flu virus strain
Children who are exposed to the flu virus strain called adenovirus 36 chance of being obese is higher than that is not much exposed to the virus.
In a study in the journal Pediatrics and child involving 124 participants, nearly 80 percent of participants were exposed to adenovirus 36 tended to be obese. Average weight of 23 kg more than participants not exposed to the virus.
2. Air conditioning
According to a study in 2006, when one lives in a comfortable temperature, the body did not need to work hard to keep your body temperature cool or warm aka lazy. As a result, the body can not control food intake.
This is consistent with other findings of the study published in the International Journal of Obesity this. Researchers found that in the South where the highest rates of obesity in the U.S. population reported that the percentage of homes with air conditioning increased from 37 percent (1978) to 70 percent (1997).
3. Working mothers
Children whose mothers work are more likely to be obese than children whose mothers stay at home (housewife). The conclusion was obtained after a team of researchers from University College London studied weight 8552 children in 1965 and compared with 1889 children in 1991.
From there, researchers found that most participants of the 1991 children whose mothers worked were more likely to be overweight than children whose mothers stay at home, while the children of the year 1965 more had mothers who did not work so not obese.
However, the authors claimed not looked at diet or physical activity of participants while they take responsibility for the conditions / risk obese person.
4. Lack of sleep
Not getting enough sleep quota will increase a person's risk of obesity. That revealed a 2007 study in the journal Archives of Disease in Childhood.
Not only that, in particular the study also pointed to a number of hormonal changes such as glucose intolerance as one of the precursors of diabetes caused by the body does not get sufficient rest.
Another study suggests that sleep duration is limited can trigger hunger and fatigue, resulting in that person lazy to do physical activity that leads to weight gain. Studies conducted in 2009 are presented in the journal Critical Reviews in Food Science and Nutrition.
5. Tonsillectomy
The team of researchers from St. Louis University, Missouri found that children who perform tonsillectomy had experienced more weight gain after surgery than children who did not undergo surgery.
After reviewing the nine studies published between the years 1970 to 2009, researchers found that weight gain and body mass index (BMI) can be seen more than 7 years postoperatively. BMI increased from 5.5 percent to 8.2 percent after tonsils removed.
So while tonsillectomy can relieve other health problems caused by tonsillitis, this procedure also increases the child's appetite.
6. Turn the lights on while sleeping
A study found that fixed room lights while sleeping at night in fact can add several inches of waist circumference someone.
Researchers exposes a number of mice with a dim light at night over eight weeks. At the end of the period, it was the rats gained weight 50 percent more than the mice who spent the night in total darkness, even though both groups were given the amount of food and physical activity are the same.
But the researchers emphasize the results of this study only apply to people who eat late evening or late at night.
7. Got older mothers
A study in 2007 and featured in the journal Archives of Disease in Childhood revealed that children born to mothers aged 30 years and over have the opportunity to body fat from 2.6 to 2.8 percent more than children born to mothers whose age at under 25 years old.
In line with that study, another study conducted in 1997 and included in the Journal of the American Medical Association found that the rate of obesity in girls aged 9-10 years who were born by his mother when he was 35 years and over will be higher when compared with children women whose mothers gave birth to them at the age of 21 years and under.
8. Exposure to environmental pollutants
Pollution can affect a person's metabolism. This was revealed by a study published in the journal Critical Reviews in Food Science and Nutrition and the International Journal of Obesity.
Chemical compound bisphenol A and polybrominated diphenyl turns are found in the human body and cause obesity because they interfere with the endocrine system or the signal settings on a variety of hormones in the body.
Not only that, pesticides can also affect hormone synthesis and metabolism via the food chain. Whereas metabolic system chaotic and uncontrolled can lead to weight gain.
9. Have mothers who eat a high-fat diet during pregnancy
Researchers from the University of Cincinnati and the Medical College of Georgia found that rats fed a high fat diet were more likely to have babies who are excessive in size than rats fed a normal diet. Though excessive size at birth is a risk factor for the emergence of obesity in the future.
The study published in the FASEB Journal revealed that the baby mice is caused by oversized parent who eat a lot of fat during pregnancy so that the placenta to provide too many nutrients to the fetus. According to researchers, a similar condition also occurs in humans.
10. Consumption of drugs
Apparently certain drugs are taken to control or prevent depression, diabetes, hypertension and pregnancy can lead to unwanted weight gain. This was revealed by a study in 2009 which featured in the journal Critical Reviews in Food Science and Nutrition.
