NEW YORK (Reuters Health) – A low-key, long term approach to teen weight loss produced modest benefits in a clinical trial, Australian researchers report, though a version of the program that added texts and emails didn’t help kids slim down any further.
The study, by Binh Nguyen at the University of Sydney and colleagues, included 151 teenagers in a 24-month program called Loozit, based on group behavior-modification sessions for teens and their parents.
At the 12-month mark, 40 percent of the teens had reduced their body mass by at least five percent and a quarter had reduced by at least 10 percent, though most remained overweight.
Despite the small effect on weight, Elissa Jelalian of Brown University in Providence, Rhode Island, said the results are promising because the program was less intensive than other weight loss efforts, and yet had nearly the same impact.
“I think it’s certainly worthy of further investigation,” Jelalian, who was not involved in the new work, told Reuters Health.
During the first two months of Loozit, the kids, who were between 13 and 16 years old, participated in seven weekly group sessions that focused on healthy eating habits, increasing physical activity, decreasing time spent in front of a screen and improving self esteem.
They also spent some time exercising and preparing and tasting foods during the sessions.
Parents, too, attended weekly group sessions where lifestyle-modification was discussed.
For the next 22 months, teens and parents went to booster sessions every three months.
The study’s results, published in the Archives of Pediatrics & Adolescent, only include outcomes from the first 12 months of the program, which 124 kids completed.
Jelalian said other weight loss programs for kids have relied on group interventions, “which I think can be helpful. They try to mobilize other kids their age who are dealing with similar challenges and to create a peer group.”
The differences between Loozit and other programs is that the kids only go through 14 sessions over two years, compared to about 20 in other cases, and the discussions are held in community locations rather than in academic or hospital settings.
Most studies of teen weight-loss approaches have centered on more intensive and heavily monitored interventions, sometimes in in-patient settings, the researchers note.
The other thing Nguyen’s group did differently is that half of the kids also received text messages, emails and phone calls to follow up and coach them through the program.
“That’s the direction a lot of people are going. And it makes sense, teens are plugged in,” said Jelalian, who was not involved in this study. “Unfortunately, it didn’t look like that added anything to their findings.”
After the 12 months there were no differences in weight loss, cholesterol levels, mental health and behavioral measures between the two groups.
“It is possible that the (additional contact) provided was too mild and that participants could have benefited from more frequent, intensive contact,” Nguyen wrote in an email to Reuters Health.
She added that the results don’t prove that coaching through texts or emails is ineffective, and future research should look at whether more frequent contact could help make a difference.
There were positive differences between where the teens started out and where they ended up, the researchers point out.
The kids had lower cholesterol and triglyceride levels at the end of the year as well as higher scores on measures of self worth, academic and athletic abilities, and social acceptance.
On average, the kids actually gained weight — which isn’t necessarily surprising, given that they grew more than an inch during the study period.
To account for this, the researchers looked at changes in the kids’ body mass index (BMI), a measure of weight relative to height.
After adjusting for a child’s age and sex, the researchers found a slight drop in BMI after 12 months, indicating that the kids were shifting toward a more normal body size, although they were still overweight.
Jelalian said it’s important to try new approaches to getting overweight and obese kids to lose weight, because research has typically focused on adults or younger children.
“There are some developmental considerations for adolescents that are unique,” she said, such as the onset of puberty and a growing independence from parents.
“There are few other programs for this age group and that are sustainable in community-based settings,” Nguyen said. “We know of no others in Australia that have been tested in research studies.”
She said she would definitely recommend Loozit for overweight teens. And that her team is following up with a study on the results of the full 24 months of the trial.
So far, “These findings highlight the potential benefits of a low intensity weight management program targeted at adolescents that is sustainable in community settings,” Nguyen and her colleagues write in their report.

NEW YORK (Reuters Health)-overweight women with diabetes may be able to cut their risk of leak urine if they shed some pounds, a new study suggests.
Extra pounds, especially in the abdomen, be considered as a risk factor for urinary incontinence. And some studies have found that when overweight women even a modest amount of weight drop, they can curb their risk of incontinence.
Type 2 diabetes, which often goes hand in hand with obesity, it is also a risk factor for Urinary leakage, regardless of the weight. So weight loss could be especially useful for heavy women with diabetes–but studies had not looked at the question till now.
In the new study, the researchers found that overweight diabetic women who took diet and exercise changes lost an average of 17 pounds more than a year. And with the weight loss came a lower risk of developing incontinence.
More than a year developed 10,5% of women in the diet-and-exercise group new problems with urine leakage. That compared to 14% of the women who had not lifestyle changes.
“Overweight and obese women with type 2 diabetes should consider weight loss as a way to increase their risk of developing urinary incontinence,” said lead researcher Suzanne Phelan, California Polytechnic State University, Reuters Health by email.
And of course, she added, there are already known advantages of shedding those extra pounds–such as better diabetes control and a lower risk of cardiovascular disease.
The findings, reported in the Journal of Urology, are based on 2739 middle-aged and older women who were part of a larger diabetes study.
In the beginning, the women were randomly assigned to one of two groups. In one group were women encouraged to cut calories and exercise for three hours per week. The other group had three diabetes education sessions.
Overall, women in the lifestyle Group had a lower rate of urinary incontinence in the coming year. And it didn’t take a lot of weight loss start to make a difference, Phelan of team found.
A woman for every two pounds lost, the chances of developing incontinence baptized by three percent.
On the other hand, seems to help women who already had weight loss not urine leakage problems in the study of start.
“We are not sure why weight loss appeared to assess the impact of prevention, but not the resolution of urinary incontinence,” Phelan said.
It is possible, she said, that weight loss is more effective in preventing, instead of treating, urine leakage. Or can just there are too few women with existing to detect an effect of urinary incontinence, weight loss Phelan added.
It is also unclear how good are for the decline of incontinence risk–it could be related to exercise or the lowering of blood sugar levels, for example.
Urinary incontinence is very common among women–in large part because vaginal childbirth is a major risk factor.
A recent study by the U.S. adults found that approximately 53 percent of women older than 20 said they had problems with urine leakage in the past year. That was up from less than half of the women respondents some years earlier.
Researchers said that the increase was partly explained by rising prices of diabetes and obesity.

Whenever I walk down the streets, I can’t help but see more people who are way above what is considered safe and normal weight. I begin to wonder if obesity is becoming a modern trend or more likely, an epidemic.
Media has done enough negative feedback to those who suffer obesity and to say that it is becoming a widespread disease, may be an explicit case of Continue reading
