Interventions to increase physical activity among healthy adults: meta-analysis of outcomes.

Objectives: We conducted a meta-analysis summarizing the effects of interventions designed to increase physical activity among healthy adults.

Methods: Our comprehensive searches located 358 reports eligible for inclusion. We used random-effects analyses to synthesize data, and we used meta-analytic analogues of regression and analysis of variance to examine potential moderator variables.

Article alerts: Items from 2009, Part II.

This second installment of the 'Article Alerts' feature section more than doubles the collection's number of items. The print and archive versions now include 200 and 2579 items, respectively. Remarks are offered on inclusion criteria, anticipated growth of the archive version, and a related resource.

Article alerts: Introduction and items from 2009, part I.

This 'Article Alerts' feature is intended to apprise readers of recent methodological work in research synthesis and compile previous such contributions from various outlets. In this first installment we introduce the feature by commenting on its main aims and distinguishing between the print and archive versions. The feature's content and process are also described, including encouragement of interactive contributions from readers.

Meta-analysis of workplace physical activity interventions.

Context: Most adults do not achieve adequate physical activity levels. Despite the potential benefits of worksite health promotion, no previous comprehensive meta-analysis has summarized health and physical activity behavior outcomes from such programs. This comprehensive meta-analysis integrated the extant wide range of worksite physical activity intervention research.

Random-effects meta-analysis of correlations: Monte Carlo evaluation of mean estimators.

Several authors have cautioned against using Fisher's z-transformation in random-effects meta-analysis of correlations, which seems to perform poorly in some situations, especially with substantial inter-study heterogeneity. Attributing this performance largely to the direct z-to-r transformation (DZRT) of Fisher z results (e.g.

Interventions to improve medication adherence among older adults: meta-analysis of adherence outcomes among randomized controlled trials.

Purpose: This study investigated the effectiveness of interventions to improve medication adherence (MA) in older adults.

Design And Methods: Meta-analysis was used to synthesize results of 33 published and unpublished randomized controlled trials. Random-effects models were used to estimate overall mean effect sizes (ESs) for MA, knowledge, health outcomes, and health services utilization.

Meta-analysis of quality-of-life outcomes from physical activity interventions.

Background: Interventions to increase physical activity among adults with chronic illness are intended to improve quality of life and reduce disease complications or slow disease progression.

Objective: The aim of this study was to integrate quality-of-life outcomes from primary research studies testing interventions to increase physical activity among adults with chronic illness.

Methods: Extensive literature searching strategies were used to locate published and unpublished primary research testing physical activity interventions.

Meta-analysis of correlations revisited: attempted replication and extension of Field's (2001) simulation studies.

In 2 Monte Carlo studies of fixed- and random-effects meta-analysis for correlations, A. P. Field (2001) ostensibly evaluated Hedges-Olkin-Vevea Fisher-z and Schmidt-Hunter Pearson-r estimators and tests in 120 conditions.

Meta-analysis of interventions to increase physical activity among cardiac subjects.

Background: Extensive primary research has tested interventions to increase physical activity (PA) among adults with cardiovascular disease. This meta-analysis integrates the extant research about how to increase PA in cardiac samples.

Methods: Extensive literature searching located published and unpublished intervention studies that measured PA outcomes.

Improved Fisher z estimators for univariate random-effects meta-analysis of correlations.

Several authors have studied or used the following estimation strategy for meta-analysing correlations: obtain a point estimate or confidence interval for the mean Fisher z correlation, and transform this estimate to the Pearson r metric. Using the relationship between Fisher z and Pearson r random variables, I demonstrate the potential discrepancy induced by directly z-to-r transforming a mean correlation parameter. Point and interval estimators based on an alternative integral z-to-r transformation are proposed.

Meta-analysis of health behavior change interventions in type 1 diabetes.

Objectives: To meta-analyze research testing interventions to improve health behaviors including exercise among adults with type 1 diabetes.

Methods: Multiple literature-searching strategies identified published and unpublished studies reporting glycated hemoglobin outcomes. Fixed- and random-effects meta-analyses included moderator effects.

Meta-analysis of patient education interventions to increase physical activity among chronically ill adults.

Objective: This meta-analysis integrates primary research testing the effect of patient education to increase physical activity (PA) on behavior outcomes among adults with diverse chronic illnesses.

Methods: Extensive literature searching strategies located published and unpublished intervention studies that measured PA behavior outcomes. Primary study results were coded.

Physical activity interventions among adults with arthritis: meta-analysis of outcomes.

Objective: Due to reduced physical activity, adults with arthritis experience significant disability and comorbidities including cardiovascular disease. This meta-analytic review integrates results from primary research studies testing interventions to increase physical activity in arthritis patients.

Methods: Extensive literature searching strategies were employed to locate published and unpublished empirical studies testing physical activity interventions.

Meta-analysis of the effect of exercise interventions on fitness outcomes among adults with type 1 and type 2 diabetes.

This review applied meta-analytic procedures to integrate primary research that examined exercise fitness outcomes among adults with type 1 or type 2 diabetes. We used extensive literature searching strategies to locate published and unpublished intervention studies that tested exercise interventions. We conducted meta-analytic procedures using both fixed- and random-effects models.

A meta-analysis of exercise interventions among people treated for cancer.

Goal: This review applied meta-analytic procedures to integrate primary research findings that tested exercise interventions among people treated for cancer.

Methods: Extensive literature searching strategies located published and unpublished intervention studies that tested exercise interventions with at least five participants (k = 30). Primary study results were coded.
