Research projects in Obesity and Physical Activity | PRIME Health

Research projects in the area obesity and physical activity by the PRIME Health research group.

SCOUTS and SPRING

This series of projects was started when local governments realized that overcrowding at preschool and increasing assignments in the field of health promotion, which often competed for resources and attention and put a strain on the preschool staff.

At the same time the preschool staff was aware of health risks that the children (and they themselves) were exposed to such as obesogenic environment and cramped sun-exposed areas (a problem from spring to autumn). In addition, the short-term consequences (overweight, sunburn, stress) as well as the long-term consequences (increased risk of morbidity related to a lack of physical activity and skin cancer (the most rapidly increasing cancer in Sweden), and mental ill-health.

We wanted to test the hypothesis that outdoor physical environment has an impact upon the children’s physical activity and sun exposure. This cross-sectional study was a collaboration between KI, the Swedish university of Agricultural Sciences, Haninge municipality, the Radiation Protection Authority and the Stockholm County Council.

The aim of this study was to simultaneously examine the impact of outdoor environment upon physical activity, sun exposure and attention abilities, by triggering spontaneous play underneath and between vegetation, which in extension triggered physical activity and sun-protective behaviour.

The study found that outdoor environment that fulfilled certain criteria increased children’s physical activity by >20%, made outdoor stay all day possible without sunburn, and increased attention ability scores. This has led to improvement of preschool environments in the municipality of Nynäshamn, Stockholm County, City of Malmö, and other municipalities in Sweden are following suit.

Funding from Stockholm County Council, The Radiation Protection Authority (former Radiation Protection Institute) The Research Council Formas, the municipality of Nynäshamn.

Kidscape I

Collaborators: The project is a collaboration between Karolinska Institutet&nbsand the University of Gothenburg and Linnaeus University (Anders Raustorp, Peter Pagels, Andreas Fröberg), the Swedish University of Agricultural Sciences (Fredrika Mårtensson), the Universities of Lund and Copenhagen (Margareta Söderström), and North Carolina State University (Robin Moore, Nilda Cosco, and Brad Bieber).

This project is a continuation of the 2nd of the project series (SCAMPER). The aim was to explore if the findings of the study that was conducted in the Stockholm would be similar or different in areas of different latitudes, climates and landscapes. The same concept was tested in Research Triangle Park (Raleigh), North Carolina, USA and in the City of Malmö.

It was found that the findings in Stockholm also held true for other places. During the course of this study the local government of Nynäshamn had integrated new routines in their interior management so that upgrading of preschool outdoor environment is a natural component in land use issues as well as certain components are included in mandatory occupational safety inspection rounds.

Other municipalities in Stockholm County, City of Malmö, and other parts of Sweden start to follow suit, following a recommendation by the National Board of Housing, Building and Planning (Boverket) as a consequence of amongst others this project.

Kidscape II

The point of departure for the Kidscape II-study was to investigate the significance of the outdoors for the same variables at compulsory school across ages and seasons during one academic year.

Among children, the lack of physical activity (PA) is widespread, and 80-90% of all skin cancers depend on overexposure to ultraviolet (UV) radiation in early life. The combination of sufficient PA and suberythemal UV exposure dispersed over the day is vital to general wellbeing and bone health.

In Western societies children increasingly spend most of the workday sitting indoors during long regulated schooldays which may have implications for sustainable health benefits like bone growth and a healthy body weight. Studies have shown that outdoor stay is a strong predictor of primary school children's physical activity.

There is evidence that from an early age physical activity is related to physical capacity, improved motor skills, quality of life and self-esteem, as well as reduction of common diseases such as cardiovascular disease and osteoporosis. One obstacle of outdoor stay may be hazardous exposure to UV radiation from the sun.

The aim of this project is to investigate the combined impact upon physical activity and UV exposure in schoolchildren across different ages and seasons in schools with a different set-up of play settings.

School Grounds Intervention

This project began in 2010 as a result of Malmö city’s Green School Grounds initiative which involved the redevelopment and greening of two school grounds in Malmö. The longitudinal character of school ground greening requires follow-up study after some time had passed and the greenery had become more established, before drawing further conclusions on the effects of school ground greening.

The aim of the project is to continue with the work started in the previous study, with a focus on analysing the data collected in order to see how schoolyard design as a whole and the presence of vegetation affects children’s activity and use of their schoolyard.

Funding from the City of Malmö

A dissonance-based psychosocial intervention study to improve quality of life, eating behaviour, physical activity and sedentary time in women after Roux-en-Y gastric bypass surgery

The overreaching goal of the RCT is to find ways of optimizing the outcome after Roux-en-Y gastric bypass surgery, not only in terms of weight loss, but also and primarily in terms of health-related quality of life, eating behaviour, body esteem, social adjustment, physical activity (PA) and sedentary time.

An observational study to investigate the effect of maternal Roux-en-Y-gastric bypass on the families’ physical activity, sedentary time, eating behaviour and psychosocial outcomes

The study includes women with a large weight loss induced by obesity surgery and their spouses and children. Several outcome measures such as physical activity, sedentary time, eating behaviour, body-esteem, self-concept, sleep quality, depression and anxiety has been measured and evaluated during several follow ups, up to five years after surgery.

The overall aim was to see how Roux-en-Y gastric bypass surgery and its consequences could affect the whole family, not only with focus on weight loss. After surgery the patients need to change their life style and can only eat small portions and usually not to fat or sugary beverages which all together with the change of anatomy from surgery leads to massive weight loss.

Some of the women have also participated in qualitative interviews to explore their experiences and perceptions of physical activity after surgery.
