A systematic review and meta-analysis of lifestyle interventions for informal caregivers of older adults: effects on behavioral change, mental health, and physical health.
Synthesis in The Gerontologist, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
BACKGROUND AND
objectivesInformal caregivers of older adults often experience poorer lifestyle behaviors and elevated risks of physical and mental health problems. This systematic review and meta-analysis evaluated the effects of lifestyle interventions on behavioral, mental, and physical health outcomes among caregivers of older adults, and explored whether intervention characteristics influenced outcomes. RESEARCH DESIGN AND
methodsFollowing the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines (PROSPERO CRD42023439797), a systematic search was conducted using PsycINFO, MEDLINE, and EMBASE up to July 11, 2025. Randomized controlled trials were included. Pooled estimates were calculated using random-effects meta-analysis. Risk of bias was assessed using the Revised Cochrane Risk of Bias tool.
results21 studies (N = 2,099) were identified, with 17 included in the meta-analysis. Most interventions focused on physical activity, few addressed sleep or nutrition and none targeted smoking or alcohol use. Pooled estimates derived mainly from physical activity interventions suggested a small reduction in depressive symptoms (SMD = -0.34, 95% CI -0.47 to -0.20). Subgroup analyses suggested that depressive symptom reductions reached statistical significance only in hybrid physical activity interventions combining in-person sessions with technology-supported monitoring, but not in telephone-based or in-person formats. Most studies were rated as high risk of bias. DISCUSSION AND IMPLICATIONS: Preliminary findings, largely derived from physical activity interventions, suggest a small reduction in depressive symptoms, with no consistent effects for physical activity, sleep quality, caregiving burden, stress, or self-rated health. The evidence is limited in scope and rigor. Future research may target a broader range of lifestyle behaviors.
