The effect of weight loss on health-related quality of life: systematic review and meta-analysis of randomized trials.

The aim of this study was to examine the effect of weight loss on health-related quality of life (HRQL) in randomized controlled intervention trials (RCTs). MEDLINE, HealthStar and PsycINFO were searched. RCTs of any weight loss intervention and 20 HRQL instruments were examined. Contingency tables were constructed to examine the association between statistically significant weight loss and statistically significant HRQL improvement within five HRQL categories. In addition, Short Form-36 (SF-36) outcomes were pooled using random-effects models. Fifty-three trials were included. Seventeen studies reported statistically significant weight loss and HRQL improvement. No statistically significant associations between weight loss and HRQL improvement were found in any contingency table. Because of suboptimal endpoint reporting, quantitative data pooling could only be performed using 25% of SF-36 trials in any one model. Significant improvements in physical health were found: mean difference 2.83 points, 95% CI 0.55-5.1, for the physical component score, and mean difference 6.81 points, 95% CI 2.99-10.63, for the physical functioning domain score. Conversely, no significant improvements in mental health were found. No significant association was found between weight loss and overall HRQL improvement. Weight loss may be associated with modest improvements in physical, but not mental, health.

Factors limiting evaluation of health care programs for the homeless.

The problem of homelessness and the need for health care by homeless people does not seem to be subsiding. All indications are that current legislation to implement dramatic welfare reform will eventually increase the number of homeless persons. Evaluation to guide, monitor, and select the most effective approaches in the provision of health care will remain a key element in health care delivery. Although barriers regarding evaluation of homeless health care have been reported by previous researchers as similar, the results in this study document findings elicited from administrators in the field. The administrators have the expertise to address some of the more common barriers and reduce them. Ways to approach this endeavor and to support staff in participating in and successfully integrating evaluation activities into health care provision will require attention of funding agencies, program administrators, and inclusion of staff and clients in planning. As the era of managed care becomes the focus of how health care is delivered, evaluation of existing programs will be essential to their survival. The descriptive information obtained in this exploratory study provides useful instruction for considering issues that need to be addressed in planning and implementing evaluation of health care to homeless persons.

A national survey to identify evaluation criteria for programs of health care for homeless.

We know that programs to deliver health care to the homeless are springing up all over the nation, but are they effective? Hunter, Crosby, Ventura and Warkentin attempt to get a sense of what data is being collected. In doing so, they identify the difficulties in collecting data on this transient population.
