The width of the hips is usually used to measure the level of obesity. However, research from Australia, recently, also found that if the hip can reduce the possibility of premature death. Because, big hips protect against metabolic disorders such as diabetes (read: Waist Measure of Obesity).

Deakin University in Melbourne, Australia, found that if a way which is taken almost as a measure of obesity. The researchers measured waist and hip circumference that will reveal a strong relationship between diabetes and mortality.

The study is the result of cooperation with Sweden, Mauritius,Finland, Britain, and Denmark. “By accounting for the protective effect of hip circumference, we were able to isolate the negative health risks, as measured by waist circumference,” said Professor Stefan Soderberg from the University of Umea,Sweden.


Caffeine Can Make Up or Down Estrogen Levels Young Women

Daily intake of caffeine can have other effects besides just increasing energy. A new study finds drinking coffee or other caffeinated beverages can affect estrogenlevels of a young woman can go down or up.The impact of caffeinated beverages may vary based on race. In white women, for example, coffee may reduce estrogen. While the coffee Asian women have the opposite effect, increasing the levels of these hormones.

“This study did not examine older women, but women of childbearing age who regularly consume a cup of tea every day. They consume tea regularly every day and without the slightest worry,” the researchers said.

Effects of caffeine on very minimal estrogen levels in healthy women, and have no impact on the overall health of ovulation or, at least in the short term.

“This study is important physiologically because it helps to understand how caffeine is metabolized by groups of genetically distinct. But for women of reproductive age, drinking coffee will not alter significantly the clinical hormonal function,” said Dr. Enrique Schisterman, a senior researcher at the National Institutes of Health as reported from TheNewYorkTimes.

The study has analyzed data on more than 250 women who checked 1-3 times a week for two menstrual cycles. The study participants gave blood samples together with details of behaviors such as exercise, eating, and smoking. On average, they consume about 90 mg of caffeine a day, equivalent to about one cup of coffee.

After controlling for several variables, such as age and diet, the researchers found that among Asian women who consume 200 mg or more of caffeine a day had higher estrogen levels compared with those who consumed less than that amount.Similar patterns were seen among black women, although not statistically significant.

However, the white woman 200 mg or more caffeine appeared to have little effect on lowering estrogen levels. Approximately 90 percent of women between the ages of 18-34 years drink caffeine equivalent of 1-2 cups of coffee every day.

“The reason why caffeine has a different impact on different races is not known clearly. However, the possibility of genetics has an influence on caffeine metabolism. The source of caffeine is also likely to make a difference. Researchers have examined the caffeine from beverages other than coffee, such as green tea and soda and associated with higher estrogen levels in all women, regardless of race. Various levels of antioxidants and other compounds in beverages, and additives such as milk and sugar, may also play a role, “said Dr. Schisterman.

For the time being, healthy premenopausal women who do not have to worry about caffeine intake in the short term. Further research is still needed to see if there might be a cumulative effect over many years or decades.

The results of these studies have been published in The American Journal of Clinical Nutrition.

USG Can be Used to Sterilizing Men in 15 Minutes

For men who no longer intend to have children, can undergo a vasectomy procedures or termination of the sperm channel through a surgical operation. But the researchers managed to find a new way to make men become sterile without the need to undergo surgery that uses ultrasonic sound (USG).

Appliance producing ultrasonic waves used in the medical world to see the condition of the fetus or called ultrasound. Recent studies in mice showed that ultrasound machines are available today can be used to kill sperm cell growth. This technology can make a man become infertile.

“Treatment without surgery ultrasound and this may reduce sperm reserves in mice significantly below levels usually seen in males are fertile,” says researcher James Tsuruta, from the University of North Carolina at Chapel Hill as reported by LiveScience.

The researchers used ultrasound equipment is commercially available and widely used in physical therapy. The idea was first proposed in 1970 by Mostafa Fahim, a researcher at the University of Missouri-Columbia who published several studies on treatment with ultrasound to kill the germ cells and cause infertility.

Machines used Fahim is now no longer available, so researchers must begin again with ultrasound equipment that has been available commercially. Researchers will then see whether ultrasound machines that currently exists has the same effect with a pioneering machine.

Sperm develop in testis through several stages. The researchers aim to destroy the early stages of sperm development, so this treatment will last for several months.

Researchers found that by turning the high-frequency ultrasound around the testes, the majority of sperm cells that already exist will die. The best results were seen after two sessions with each session for 15-minutes, and given a two-day pause. The researchers tested the sperm rats two weeks after receiving treatment.

Researchers found that the two sessions can reduce the amount of mouse sperm to zero or the index indicates the number of active sperm is very low. They also noticed that these mice have cells producing fewer sperm.

The research was conducted in mice that are much more fertile than humans. In mice, the concentration of sperm that reach 3,000 active sperm per milliliter or less can still fertilize an egg.

Whereas in humans, such amounts are considered infertile. In humans, low sperm count is said if it is below 15 million sperm per milliliter.

“However, more research is needed to determine how long the contraceptive effect and whether it is safe to use up several times. Further research is also needed to find out what special settings such as what it can deliver the best results in humans'” Tsuruta said.

The procedure to permanently prevent fertility, such as vasectomy, can lower sperm concentration up to 3 million sperm per milliliter. Researchers also confirmed that sterilization can be adjusted so that ultrasonic can be given to pets to control the population.

Month of Birth Can Affect Health

January 30, 2012 Leave a comment

Numerous studies have shown an association between temperament and health with a person’s birth month. In people who are overweight, it could be because he was born during the winter.

Horoscope or forecast based on the zodiac and the time of birth is contradicted by science. But in fact, affect the life time of a person’s birth.

Hundreds of studies published in various journals have shown that a person’s month of birth associated with characteristics such as temperament, longevity and susceptibility to certain diseases.

Scientists say that some of these findings may be false, but if you see the facts, some things have a suitability which could be coincidence.

Other effects can be very real and not caused by the alignment of the planets, but due to environmental influences during pregnancy and early life.

Here is the effect of season on the health and personality of someone who has been found in several scientific journals as reported by the LA Times:

1. Winter (December 22-March 20):

Weight loss:
The man who was born in this month tend to be obese. David Phillips of the University of Southampton in England analyzed the body weight of 1,750 British elderly people and found that 13.8% of men born in the month of January to March are obese.

Only 9.4% of those born in October through December. but in women, this trend becomes less clear.

Phillips argues that exposure to cold temperatures early in life may trigger the development of fat tissue and the influence of obesity in adulthood. Laboratory studies support this theory.

Rats exposed to cold temperatures before or shortly after birth store more energy in the form of fat, even when the temperature is no longer cold.

2004 study of 448 people found that people aged 20-45 years who were born during the winter (October-March) are more likely to have the property looking like new things, curious, do not like things that are tedious, and tend to choose a hobby of diving than Sudoku .

But when he was over 45 years, people born in winter are less interested in new things than those born in the summer. This indicates that they are faster settling.

“Season of birth affects the temperament, but we do not know exactly why. Maybe something to do with the levels of serotonin and dopamine, brain chemicals that are important in the formation of personality. Throughout the year, production of these hormones fluctuate in the mother’s body and can affect fetal development. Studies in animals shows the fluctuations caused by changes in day length, “says Lars-Göran Nilsson, psychologist at the University of Stockholm in Sweden.

Percentage of mental illness in the general population is about 1%, but the people who were born in winter are more prone to experience it.

The observations, published in 1999 in the New England Journal of Medicine, found that people born in early March in the northern hemisphere has the possibility of 11% more likely to develop schizophrenia than those born in early June or early December.

But in the southern hemisphere the equator, the pattern is reversed. People born in August and September have the lowest risk for having schizophrenia.

2. Spring (March 22-June 21)

According to Gerhard Weber, an anthropologist at the University of Vienna, people born in the spring tend to be more height. He analyzed the measurements made on the Austrian Federal Army over half a million men.

Weber found that the recruitment of men is highest in people who were born in April, and the shortest was born in October.

Although the average difference is small enough (0.2 inches or 0.5 cm), whose findings were reported in 1998 in the journal Nature this was statistically significant.

Weber in his study speculated that this effect could be due to the concentration of the hormone melatonin in the body of the mother.This hormone dependent by light exposure and induced stimulation of growth hormone.

Multiple sclerosis:
Spring births have a higher risk of disease multiple sclerosis. The disease is caused by a combination of genetic and environmental factors. Research has established that the higher the latitude location of a country, the higher prevalence of multiple sclerosis.

Among the countries of Australia, the risk in subtropical Queensland five-fold greater than in the tropical Tasmania.

A 2005 study of 17 874 Canadian patients and 11 502 British patients found that those born in the month of May has 23% increased risk of multiple sclerosis compared with those born in November.

The cause is presumably because the concentration of vitamin D deficiency in the mother when the end of the second or third trimester of pregnancy

3. Summer (June 22-September 22)

Sleep Habits:
The study found that people who repeat the year in June to September would rather stay up compared to those born in winter.

A 5720 survey of European college students published in 2009 in the journal Sleep shows that people born in August to start sleep 19 minutes slower than average.

The researcher, Vincenzo Natale from the University of Bologna, Italy, argues that the body’s internal clock has been set at first people were born.

According to Natale, in summer, abundant sunshine and maturity affect the biological clock. But the tendency to sleep late at night is also strongly influenced by genes.

“If someone has a gene that tends to like to sleep late at night were born during the summer, he will be a night of extreme type. But if he was born in the winter, he will be in the middle,” said Natale.

People born in the summer and spring greater kemungkinnya become left-handed.

A study published in 1994 in the journal Perceptual and Motor Skills examine the trend of left-handedness among men conscripted French, American baseball player, and from data collected by the U.S. Census Bureau.

The result, 41.2% of all left-handed people born in March through July.

Maryanne Martin professor of psychology at the University of Oxford and Gregory Jones of the University of Warwick confirm these results in 1999. They still can not explain why these differences occur.

Factors that may affect the variation of maternal nutrition during pregnancy, exposure to sunlight, temperature, or seasonal infections during the second trimester of pregnancy.

Children who are born in summer are more likely to develop type 1 diabetes. In this disease, the immune system kills the cells of the pancreas that produce insulin.

In a 1999 study of 1248 children with diabetes in Sweden, published the journal Archives of Disease in Childhood, children who were born in August are more likely to develop this disease.

4. Autumn (September 23-December 21)

Life span:
People born in the fall have a greater chance of living into old age. A study in 2011 that was published in the Journal of Aging Research analyzed the birth month of 1574 people who live to be 100 more then compare with his brother.

“Siblings of people who can live to 100 years of age who were born in the month of September to November have an opportunity of 30% – 50% higher can live to 100 years compared to those born in March,” said the researcher, Leonid Gavrilov of the Center on the Demography and Economics of Aging at the University of Chicago.

According to him, various factors can explain this, among others: maternal nutrition during the last months of pregnancy, seasonal infections, the temperature during birth or conception and levels of vitamin D.

Research conducted in Scandinavia, the Netherlands and Japan showed that the risk of higher food allergy found in children born in autumn or winter than those born in the summer.

Allergist, Dr. Milo Vassallo from Brooklyn, NY, 1000 saw more cases associated with acute food allergy reactions in a Boston hospital. He found that the birth of autumn and winter have the possibility of having food allergies 53% higher. According to him, it could be caused by seasonal fluctuations of vitamin D. Vitamin D deficiency can weaken the immune system.

“Because this is a good source of vitamins and supplements from the sun, then the risk of allergy depends on the place of residence. The latitudes higher and excessive fluctuations in exposure to sunlight causes a child born in the fall and winter in Boston has a higher risk of allergies compared with children in Los Angeles, “said Dr Vassallo.
