The Effect of Motivational Interviewing on Weight Loss on Obese Males

11 August 2012


Background: Obesity is a serious health concern throughout the world. This systematic review aims to see if the use of motivational interviewing provides more successful results in weight loss in males than more traditional weight loss education.

Method: An exhaustive literature search was performed using MEDLINE, CINAHL and Web of Science databases using the keywords “motivational interviewing,” “obesity,” “weight loss,” “behavior change,” and “male”. From here, articles were chosen based on title and then abstracts were reviewed. The articles were then assessed using GRADE criteria.

Results: Only two articles that fit the topic and inclusion/exclusion criteria were included in this review. Groeneveld et al study showed a mean loss of 0.9kg (1.98 lbs) in the participants in the intervention group who received MI, versus a mean gain of 0.9kg (1.98 lbs) in the control group who did not receive MI. It is apparent in this study that motivational interviewing did have statistically significant outcomes on weight loss when compared to more traditional weight loss education, p < 0.05.

Rocha-Goldberg et al study showed that after the six week study, participants did show a mean decrease in weight of 2.9lbs. Although in this pilot study, there was no control group to measure the intervention group against.

Conclusion: Motivational interviewing does have statistically significant results on weight loss in adult males.
