Effectiveness of weight loss interventions for obese older adults.

OBJECTIVE

The consequences of obesity among older adults are significant, yet few obesity interventions target this group. Unfamiliarity with weight loss intervention effectiveness and concerns that weight loss negatively affects older adults may be inhibiting targeting this group. This paper reviews the evidence on intentional weight loss and effective weight loss interventions for obese older adults to help dispel concerns and guide health promotion practice.

DATA SOURCE

PubMed articles.

STUDY INCLUSION AND EXCLUSION CRITERIA

Randomized controlled trials examining behavioral and pharmaceutical weight loss strategies with 1-year follow-up targeting obese (body mass index ≥ 30) older adults (mean age ≥ 60 years), and studies with quasi-experimental designs examining surgical weight loss strategies targeting older adults were examined.

DATA EXTRACTION

Abstracts were reviewed for study objective relevancy, with relevant articles extracted and reviewed.

DATA SYNTHESIS

Data were inserted into an analysis matrix.

RESULTS

Evidence indicates behavioral strategies are effective in producing significant (all p < .05) weight loss without significant risk to obese older adults, but effectiveness evidence for surgical and pharmaceutical strategies for obese older adults is lacking, primarily because this group has not been targeted in trials or analyses did not isolate this group.

CONCLUSION

These findings support the promotion of intentional weight loss among obese older adults and provide guidance to health promotion practitioners on effective weight loss interventions to use with this group.
