Investigators identify successful weight control strategies for adolescents

02.12.2009
Adolescent obesity is a major public health problem that impacts one out of every three children, resulting in 4-5 million overweight youth in the United States.

In a study published in the December 2009 issue of the Journal of the American Dietetic Association, researchers evaluated differences in weight control behaviors, including dietary intake and physical activity, comparing overweight adolescents who lost weight and those who did not in order to better understand which strategies could be most effective.

Research has documented that one of the strongest predictors of adult obesity is adolescent obesity, with 70% of obese adolescents becoming obese adults. Identifying effective weight control strategies for adolescents is important and could help influence interventions for obesity in youth.

Investigators surveyed 130 adolescents, 62 who had been successful in losing weight and 68 who had been unsuccessful. Questioning adolescents and their parents, the authors evaluated weight control strategies, sedentary behaviors, dietary intake, physical activity, weighing frequency and current weight status.

In this pilot study weight control strategies were broken down into four categories. The first, "Healthy Weight Control Behaviors" (HWCB ), included eating less calories, increasing exercise, eating less high fat and junk food, drinking less soda, drinking more water, weighing oneself, eating more fruits and vegetables, and engaging in different kinds of exercise. The second category, "Unhealthy Weight Control Behaviors" (UWCB) included laxatives, vomiting, diuretics, smoking, and fasting. The third category, "Extreme Dietary Changes" (EDC), included use of liquid diet supplements, the Atkins diet, a structured diet, fasting, and increased protein consumption. The fourth category, "Structured Behaviors" (SB), included eating a certain amount of calories, counting calories, recording food intake, and working with a professional

The successful adolescents reported increased exercise levels, drinking less soda, walking more/climbing stairs and self-weighing. Overall, a higher percentage of adolescents who lost weight reported using 6 or more Healthy Weight Control Behaviors compared to those who did not lose weight. Fewer of the adolescents who lost weight reported using any of the Structured Behavior strategies assessed. Of note, there were no differences identified between the groups regarding the use of Unhealthy Weight Control Behaviors or Extreme Dietary Changes.

Kerri Boutelle, PhD, and co-authors state, "First of all, our findings provide a glimpse of optimism that adolescents can lose a significant amount of weight and maintain this weight loss. Second, our findings suggest that there are no magical solutions, and that behaviors such as eating more fruits and vegetables and eating less fat and decreasing sedentary time seem to offer the most promise for success...Self-weighing may be a helpful monitoring tool for overweight adolescents; in the current study, the largest percentage of adolescents who lost weight reported weighing themselves on a weekly basis, while the largest percentage of adolescents who did not lose weight reported weighing themselves less than monthly. Lastly, unhealthy weight control behaviors were not associated with being in the group that lost weight. Adolescents would benefit from hearing this information from dietitians and other health care providers to prevent development of unhealthy weight control behaviors. Findings from the current study have the potential to guide both future research studies and clinical interventions on obesity in adolescents."

Im Focus: Ultrafast snapshots of relaxing electrons in solids

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!

When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...

Im Focus: Quantum Sensors Decipher Magnetic Ordering in a New Semiconducting Material

For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.

Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
