Effects of health at every size® interventions on health-related outcomes of people with overweight and obesity: a systematic review.
CONTEXT
The growing use of interventions based on the Health at Every Size® (HAES®) in obesity management.


OBJECTIVE
This study aimed to summarize the health-related effects of HAES®-based interventions on people with overweight and obesity.


DATA SOURCES
MEDLINE (via PubMed), EMBASE, Cochrane Library, LILACS, Google Scholar, OpenGrey and Grey Literature Report.


STUDY SELECTION
A systematic review of studies published until January 2017 reporting on HAES®-based randomized and non-randomized controlled trials in people with overweight and/or obesity.


DATA EXTRACTION
Fourteen papers met the inclusion criteria. The assessed studies included the following tests: blood profile, blood pressure, anthropometry, eating behaviour, energy intake, diet quality, psychological and qualitative evaluations.


RESULTS
The HAES® interventions benefited both the psychological and physical activity outcomes, besides promoting behavioural and qualitative changes in eating habits. On the other hand, the results regarding cardiovascular responses, body-image perception and total energy intake were inconsistent.


CONCLUSIONS
Despite improving the cardiovascular status, eating behaviours, quality of life and psychological well-being in participants, other large long-term clinical trials should be performed to establish the effectiveness of HAES®-based interventions in improving health for people with overweight and obesity.
