It is also important to reach groups that are normally regarded as being at low risk of gaining weight. This is what Kristina Lindvall shows in her doctoral dissertation at Umeå University in Sweden. Participants in her study come from Västerbotten in northern Sweden and from New York State in the US.
It is often difficult for people to maintain their weight after weight loss. Instead people tend to gain back just as much or more. This is why Kristina Lindvall, a dietitian and doctoral candidate at the Section for Epidemiology and Global Health, maintains it is important for society to broaden the focus from treatment of overweight and obesity to include preventive work on weight gain.
– This is why I chose to focus on primary weight maintenance in my research, that is, the possibility of preventing weight gain among people of normal weight and overweight individuals, says Kristina Lindvall.
All participants in the study were 30-65 years of age and were recruited because they had twice participated in Västerbotten Health Study (VHU), which is carried out in Västerbotten, Sweden, or in the Upstate Health and Wellness Study, in New York State in the US.
The dissertation shows that of all the people who were of normal weight or overweight and took part in the VHU study in 1990-2004, only about one third did not gain weight. One surprising result was that younger individuals of normal weight, without type-2 diabetes, and with no risk factors for cardiovascular disease were those least likely to maintain their weight.
– This means that measures to prevent overweight and obesity may also need to include these groups, groups that are normally regarded as being at low risk for weight gain, says Kristina Lindvall.
Research interviews with VHU participants that managed to maintain their weight after weight loss showed that weight stability was seen as maintaining a balance, not only in stabilizing weight but also regarding other factors in life. Four main strategies for maintaining weight were described: “relying on your heredity,” “finding joy,” “finding routines,” and “being in control.” Kristina Lindvall claims that as a result of these findings it is important to adapt advice to fit not only those wishing to lose weight but also those wanting to maintain their weight.
In a questionnaire created to identify attitudes and behaviors that were key to maintaining weight in all groups based on age, gender, and body-mass index (BMI), major differences were revealed among the groups in the responses they provided.
– This emphasizes the importance of tailoring interventions that strive for primary weight stability in a population to age groups, gender, and BMI, says Kristina Lindvall.
Finally, American and Swedish female study participants were compared. The Swedish women gained an average of 3.5 kg in weight during the years 1999-2009, while the American women gained nearly twice as much. A partial explanation for this may be that significantly more of the Swedish women stated that they exhibited healthy behaviors. On the other hand, the difference was greater in terms of weight gain among the American women if they chose healthy behaviors over unhealthy ones.
Kristina Lindvall originally comes from Skellefteå and is a dietitian and doctoral candidate at the Department of Public Health and Clinical Medicine, Umeå University.

Quantum entanglement, a perplexing phenomenon of quantum mechanics that Albert Einstein once referred to as “spooky action at a distance,” could be even spookier than Einstein perceived.
Physicists at the University of Washington and Stony Brook University in New York believe the phenomenon might be intrinsically linked with wormholes, hypothetical features of space-time that in popular science fiction can provide a much-faster-than-light shortcut from one part of the universe to another.
But here’s the catch: One couldn’t actually ...
A star is formed when a large cloud of gas and dust condenses and eventually becomes so dense that it collapses into a ball of gas, where the pressure heats the matter, creating a glowing gas ball – a star is born.
New research from the Niels Bohr Institute, among others, shows that a young, newly formed star in the Milky Way had such an explosive growth, that it was initially about 100 times brighter than it is now. The results are published in the scientific journal, Astrophysical Journal Letters.

NASA's Hurricane and Severe Storms Sentinel airborne mission known as HS3 wrapped up for the 2013 Atlantic Ocean hurricane season at the end of September, and had several highlights. HS3 will return to NASA’s Wallops Flight Facility in Wallops Island, Va., for the 2014 Atlantic hurricane season.
During the 2013 mission, two unmanned Global Hawks flew from Wallops for the first time. The mission highlights included studying the Saharan Air Layer, following the genesis of a tropical storm, finding a unique hybrid core or center circulation in a redeveloped storm, obtaining measurements on the strongest side of ...
Nanosponges that soak up a dangerous pore-forming toxin produced by MRSA (methicillin-resistant Staphylococcus aureus) could serve as a safe and effective vaccine against this toxin.
This "nanosponge vaccine" enabled the immune systems of mice to block the adverse effects of the alpha-haemolysin toxin from MRSA—both within the bloodstream and on the skin. Nanoengineers from the University of California, San Diego described the safety and efficacy of this nanosponge vaccine in the December 1 issue of ...
