EXECUTIVE SUMMARY.
Background.
Previously, some Norwegian cause-effect studies of social inequality documenting a
social gradient in healthy diet and physical activity and knowledge about interventions
offered by the health services have been reported. Among lower socio-economic groups,
fewer eat healthy foods than among higher socio-economic groups. There are few effect
studies about interventions for helping lower socio-economic groups to eat healthy foods
and to be physically active.
OBJECTIVE
The objectives were to assess the effects of the following interventions: 1) to improve
dietary habits among different socio-economic groups, 2) to improve dietary habits in
lower socio-economic groups, 3) to increase physical activity among different socioeconomic
groups, and 4) to increase physical activity in lower socio-economic groups.
METHODS
We conducted a systematic literature search in the following electronic databases:
Medline, Embase, Cochrane Library, PsychInfo, Cinahl, Social Services Abstracts,
Sociological Abstracts, Eric, International Bibliography of the Social Sciences, Social
Sciences Citation Index, Social Care Online, C2-SPECTR, SveMed, BiblioMap, Bibsys and
Google Scholar until April 2007. Relevance and study quality is appraised according to
the Knowledge Centre’s methodological handbook
(http://www.kunnskapssenteret.no/filer/K-Handbok-2006.pdf).
We included effect studies dealing with improving diet and/or increasing physical
activity in groups with low socio-economic status, or a reduction in differences in dietary
quality and/or level of physical activity between groups with different socio-economic
status.
RESULTS
A total of five reviews and 14 primary studies are included in this report. We found
several studies that reported socio-economic data at the start of the intervention
(baseline), but they did not use background variables like income and education to
analyze differences between socio-economic groups. We chose to categorize the included
studies according to target group for intervention.
Target group 1: children
Target group 2: visitors in supermarkets
Target group 3: immigrants, minority groups
Target group 4: population in deprived areas
Target group 5: patients and high-risk groups
Target group 6: employees, unemployed
The documentation does not allow us to conclude about an effect/no effect in any of the
target group.
