Study: Doctor’s weight may influence obesity diagnosis

A survey of 500 primary care physicians around the country reveals that doctors considered overweight or obese were much less likely to diagnose obese patients than physicians at a more “normal” weight.

Doctors with a normal BMI (18.5-25) were more likely to discuss weight loss with obese patients (30% vs 18%), give advice on diet (53% vs 37%), and exercise (56% vs 38%). The study, published in Obesity, also revealed that the probability of normal BMI physicians recording an obesity diagnosis for a patient was 93 percent and only 7 percent for overweight or obese doctors.

High heels may cause muscle damage

A study published in the Journal of Applied Physiology finds that wearing high heels may lead to damage of the calf muscles.

The study included women, teens to early 30s, who had worn high heels for at least 40 hours a week for a minimum of two years. The control group consisted of women who rarely or never wore heels. The research team used ultrasound probes, electrodes, and motion-capture markers to monitor the participants as they walked barefoot and then in heels down a 26 ft long walkway.

The findings suggest that women in high heels walked with shorter and more forceful strides (even in bare feet), engaging their muscles instead of their tendons, potentially leaving them more vulnerable to injury and muscle fatigue.

People may fib more when texting

New research published in the Journal of Business Ethics shows that people may lie more frequently when text messaging.

Participants consisted of 170 business students conducting fake stock trades in person, by video, or through text.  Once trades were completed, the buyers were asked if their brokers had engaged in any deceit. After examining which brokers were considered liars, the researchers examined which form of communication was used to make the trade.

It was revealed that buyers who received information through text messages were 95 percent more likely to report a deception than if they had communicated through video. They were also 31 percent more likely to report that they were deceived than those who made the transaction face-to-face and 18 percent more likely than those who had an audio chat.

The researchers note that texting involves less scrutiny than communication methods such as video, where participants may suffer from “spotlight effect”.

Vital Statistics: Thanksgiving Edition

Thanksgiving travel costs increase

The cost of your travel plans for the Thanksgiving holiday will most likely be higher than last year. According to Orbitz Worldwide Inc, the average round trip airfare for Wednesday through Sunday to the 10 most popular destinations in the U.S. has jumped 11 percent (to $373) compared to the same period last year. Flights to New York will increase the most, rising 20 percent compared to 2010, with an average round trip price of $342.

Curious if you are heading to one of the busiest or least busy airports for the holiday? Orbitz also reviewed the top 50 airports in the U.S. based on flight bookings and found that Los Angeles International, Chicago O’Hare and Orlando International will be the three busiest airports in the country. Meanwhile, Mineta San Jose International claims the least busy title.

The price of Thanksgiving dinner is on the rise

According to the American Farm Bureau Federation, the cost of a 10-person traditional Thanksgiving dinner has jumped by 13 percent since last year. That is equivalent to $5.70 for an average total of $49.20. This is the largest increase since the study began 26 years ago.

It now costs an average of $21.57 for a 16 pound turkey, $3.91 more than 2010, making it the biggest contributor to the price increase.  A gallon of whole milk was also among the biggest gainers, rising 42 cents from last year to $3.66. Thirty ounces of pumpkin pie mix also played a part, jumping 41 cents to $3.03.

A roundup of some interesting studies making news. As always, a mention here doesn’t mean an endorsement.

1 in 25 business leaders may be psychopaths

Over at TIME, STATS fellow Maia Szalavitz discusses a new study that finds 1 in 25 business leaders may be psychopaths, a rate she points out, “that’s four times greater than in the general population.” The research team studied 203 American corporate professionals who had been chosen by their respective companies to participate in a management training program.

Psychopathic traits were evaluated using a standard checklist developed by a psychopathy expert. Psychopaths are characterized as being amoral and concerned with only their own power. It is possible that psychopaths may be overrepresented in the business environment because it caters to their strengths.

Do family dinners keep teens out of trouble?

A new study shows that family dinners may help keep teenagers away from drugs and alcohol:  58 percent of U.S. teens sit down for family dinners at least five times a week. It was found that teens who spend more time with their parents at the dinner table, spend more time with their parents in general.

On the other hand, teenagers who reported infrequent family dinners also reported spending less time with their parents. These teens were more likely to have used alcohol and to have at least one friend or classmate who engages in drug abuse.

 Optimism may be in your genes

A new study in the Proceedings of the National Academy of Sciences finds that optimism, self-esteem, and mastery may possibly have a genetic base rooted in the hormone oxytocin (aka the “love” hormone).

The study, which examined 326 participants, involved a survey and the analysis of genetic material in the saliva, looking for a combination of two variants, “A” and “G”.  Those with two “G’s” may be more likely to be optimistic; however, the study found the gene may also backfire. Certain combination of genes, such as one or two A’s may be associated with less optimism and more symptoms of depression.

 The traditional police lineup may need to be altered

According to new research by the American Judicature Society, the traditional police lineup may need some tweaking. The more common simultaneous lineup, when witnesses look at groups of people standing in front of them or in photos, can result in a higher amount of misidentifications. Witnesses tend to compare one person to another and decide who looks most like the suspect; a problem if the suspect is not actually included in the lineup. The researchers say a sequential lineup is more effective. In this method, a person looks at each person individually and says whether he or she is the suspect.

Both procedures had similar outcomes in identifying the suspect; however, the sequential method resulted in less misidentification. In the simultaneous lineups, a suspect was misidentified 18.1 percent of the time compared to 12.2 percent of the time when using the sequential method. The latter also produced fewer “not sure” responses from witnesses.

Are packed lunches unsafe for children?

A new study finds that many packed lunches may reach dangerous temperatures by the time a child eats at daycare, even when packed in an insulated container with ice packs. The study revealed that more than 90 percent of perishable items were at an unsafe temperature an hour and a half before lunch time.

The research team examined lunches of nine central Texas day care centers for children between the ages of 3 and 5, and tested the temperature of individual perishable items from 705 lunches an hour and a half before the scheduled lunch time.

About 39 percent of the packed lunches did not have an ice pack, while 45 percent had just one ice pack. More than 88 percent of the lunches were at room temperature and just 1.6 percent of perishable items were kept in the USDA recommended temperature zone. Food-borne illness is of particular concern for children under the age of 5.

Survey: Americans are losing respect for smokers

Twenty years ago, between 14 and 17 percent of Americans reported having less respect for smokers. However, a new Gallup survey of 1,016 adults reports that number has now jumped to 25 percent. Gallup points out this trend may be influenced by the shrinking smoking population, which has dropped from 27 percent in 1991 to 22 percent today.

It was found that nonsmokers are the primary source of this view, with 30 percent saying they have less respect for smokers. The survey revealed only 5 percent of smokers share this point of view. When surveyed about obesity, 12 percent said they had less respect for those who are overweight or obese, down from 16 percent in 2003. Meanwhile, more than four in five adults said their respect for a person was not influenced by the individual’s weight.

Does a friendly work environment lead to a longer life?

New research from Tel Aviv University finds that positive social interactions in the workplace may be associated with a lower risk of death. In a study of 820 adults from various fields, those who felt that they had little or no emotional support in the workplace were 2.4 times more likely to die during the course of the study.

Although a direct relationship cannot be determined, a risk factor appeared to be one’s perceived level of control. Men who reported more control in the work environment were associated with a lower risk of dying; however, the opposite was found to be true for women. The risk of death for women who reported more control rose by 70 percent. The study authors point out this may be related to the changing gender roles in the work environment over the course of the past two decades.

Business travel may negatively impact health

 A new study from Columbia University finds that frequent business travel may be associated with increased health risks. The researchers analyzed data from 13,000 people who were participating in a corporate wellness program. Approximately 80 percent of the employees traveled at least one night per month, while almost 1 percent traveled 20 nights or more per month.

The study found that those who traveled most often were 260 percent more likely to rate their health as fair to poor compared to light travelers. In addition to higher cholesterol and blood pressure, obesity was 92 percent more common in the extensive travelers.

The study is published in the Journal of Occupational and Environmental Medicine.

New report names U.S. cities with the cleanest and most polluted air

According to a new report, more than half of the U.S. population lives in areas with polluted air that can be dangerous to breathe. Some of the worst quality air can be found in California, including Los Angeles and Long Beach. On the other hand, Honolulu, Hawaii and Santa Fe, New Mexico have some of the cleanest air in the country.

Approximately 48 percent of U.S. residents live in counties where smog is too high, and about 17 million Americans live in areas affected by three pollution hazards, including smog and soot.

 What are the top sources of foodborne illness?

A new report released by the University of Florida Emerging Pathogens Institute identifies the food and disease causing microorganisms that are associated with the most risk in the United States.

The combination of poultry with Campylobacter bacteria causes the most foodborne illness in the country, affecting more than 600,000 people a year and costing $1.3 billion.

The top ten pathogen and food combinations, including salmonella and norovirus, cost the U.S.  more than $8 billion in medical costs and lost wages.

The report is available here.

Reality bites

New research suggests that those who are overly idealistic about their significant others may be more satisfied with their marriage than realists.

The study is based off of 193 couples, the average age being 27 years old, with incomes averaging between $40,000 and $70,000. Each participant completed surveys abut themselves, their significant other and their marriage every six months for a period of 3 years. Based on the information provided by each person about themselves and their partner, the research team developed a ranking of each person’s perception of their partner.

The results revealed that those who had an unrealistic image of their partner were happier with their marriage over the three years. The study authors could not determine how long this idealization may be associated with happiness due to the study’s length. The study is published in the April issue of Psychological Science.

Can staring at the computer during lunchtime cause you to eat more later?

New research from the University of Bristol in England shows that those who played a computer game while eating lunch ended up eating more later in the day.

Forty-four men and women participated in the study. Half ate lunch consisting of nine different foods while playing a computer game; the other half ate the same lunch without any distractions.

A half hour after lunch, the computer group consumed twice as many snacks as members of the other group. That wasn’t all – after being asked to recall what they ate for lunch, the gamers had much more difficulty. Lead researcher Jeffrey M. Brunstrom tells Reuters: “When our memory is poor, then at a subsequent meal we tend to select and consume a greater amount of food”.

Study shows kids are consuming large amounts of caffeine daily

A new study in the Journal of Pediatrics finds 75 percent of children between the ages of 5 and 12 consume caffeine. Not surprisingly, the study found the more caffeine the children consumed, the less they slept.

Children between the ages of 5 and 7, consumed an average of 52 milligrams per day, and children between 8 and 12 consumed about 109 milligrams. According to WebMD, that’s the equivalent of almost three 12 ounce cans of soda. The researchers found that the caffeine in the children’s diet came mainly from the consumption of soft drinks.

Study finds everyone really does need their beauty sleep

New research finds that beauty sleep not only affects your appearance, but also how others perceive you. The Swedish study analyzed 23 adults, taking photos of each participant twice. One photo was taken after getting a full eight hours of sleep and one after being awake for 31 hours after only getting five hours of sleep.

Sixty-five observers (who knew nothing about the amount of sleep the subjects had received) then randomly reviewed the photos and rated their perceptions of the participants. The photos of the sleep-deprived resulted in lower marks on both the health and attractiveness scales.
