Adolescents' dieting and disordered eating behaviors continue into young adulthood

24.06.2011
According to new study in the Journal of the American Dietetic Association

Adolescents who diet and develop disordered eating behaviors (unhealthy and extreme weight control behaviors and binge eating) carry these unhealthy practices into young adulthood and beyond, according to a study conducted by University of Minnesota researchers and published in the July 2011 issue of the Journal of the American Dietetic Association.

"The findings from the current study argue for early and ongoing efforts aimed at the prevention, early identification, and treatment of disordered eating behaviors in young people," commented lead investigator. Dianne Neumark-Sztainer, PhD, MPH, RD, Professor, Division of Epidemiology & Community Health, School of Public Health, University of Minnesota. "Within clinical practices, dietitians and other health care providers should be asking about the use of these behaviors prior to adolescence, throughout adolescence, and into young adulthood. Given the growing concern about obesity, it is important to let young people know that dieting and disordered eating behaviors can be counterproductive to weight management. Young people concerned about their weight should be provided with support for healthful eating and physical activity behaviors that can be implemented on a long-term basis, and should be steered away from the use of unhealthy weight control practices."

Using data from Project EAT-III (Eating and Activity in Teens and Young Adults), a 10-year longitudinal study aimed at examining eating, activity, and weight-related variables among young people, investigators from the Division of Epidemiology & Community Health, School of Public Health and the Department of Pediatrics, University of Minnesota, examined the records for 1,030 young men and 1,257 young women. One third of participants (29.9%) were in early adolescence (mean age = 12.8 years) at the beginning of the study and were in early young adulthood (mean age = 23.2 years) at the 10-year follow-up. Two thirds of participants (70.1%) were in middle adolescence (mean age = 15.9 years) at the beginning and were in middle young adulthood (mean age = 26.2 years) after 10 years.

Subjects were asked about dieting, extreme weight control behaviors such as fasting, using food substitutes and skipping meals, and binge eating with loss of control. Additional socioeconomic, gender, age, and race/ethnicity data was also collected.

About half of the females reported dieting in the past year compared to about a fourth of the males. The prevalence of dieting remained fairly constant from adolescence through young adulthood for females in both age groups. Among males, the prevalence of dieting stayed constant over time in the younger age cohort, but significantly increased in the older cohort as they progressed from middle adolescence to middle young adulthood (21.9% to 27.9%). In the younger females, unhealthy weight control behaviors remained constant from early adolescence to early young adulthood. Among older females, unhealthy weight control behaviors showed a statistically significant decrease from middle adolescence to middle young adulthood, but still remained very high (60.7% to 54.4%). Approximately one-third of males reported unhealthy weight control behaviors, and the prevalence remained fairly constant over the study period in both age cohorts.

For extreme weight control behaviors, significant increases from adolescence to young adulthood were found in females for both age cohorts and for the older cohort of males. Among females, the use of extreme weight control behaviors increased from 8.4% to 20.4% between early adolescence and early young adulthood and from 12.6% to 20.6% between middle adolescence and middle young adulthood. For the older males, extreme weight control behaviors increased from 2.1% in middle adolescence to 7.3% in middle young adulthood.

These behaviors tended to track within individuals and, in general, participants who engaged in dieting and disordered eating behaviors during adolescence were at increased risk for these behaviors 10 years later. Tracking was particularly consistent for the older females and males transitioning from middle adolescence to middle young adulthood. The tracking of these potentially harmful behaviors suggests that their use is not just "a phase" that adolescents go through, but instead indicates that early use of dieting and disordered eating behaviors may set the stage for continued use of these behaviors later on.

Larson, PhD, MPH, RD; Marla E. Eisenberg, ScD, MPH; and Katie Loth, MPH, RD. It appears in the Journal of the American Dietetic Association, Volume 111, Issue 7 (July 2011) published by Elsevier.

Im Focus: Can the immune system be boosted against Staphylococcus aureus by delivery of messenger RNA?

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.

Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.

We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...

Im Focus: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.

Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
