Depressive symptoms and incident cancer risk in middle-aged and older Chinese adults: Findings from CHARLS.

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
Depression and cancer are major public health concerns worldwide, particularly among aging populations. This study aims to investigate the association between depressive symptoms and incident cancer among middle-aged and older Chinese adults. We analyzed data from the 2015 to 2020 China Health and Retirement Longitudinal Study, a nationally representative cohort of Chinese adults aged 45 and older. Depressive symptoms were assessed using the 10-item Center for Epidemiologic Studies Depression Scale at baseline. Incident cancer cases were identified through self-reported physician diagnoses during follow-up waves. Cox proportional hazard models were used to estimate the association between baseline depressive symptoms and subsequent cancer incidence, adjusting for sociodemographic factors, lifestyles, and health status. Among 13,132 participants (median age = 60 years, 46.9% male) without a history of cancer at baseline, 250 new cancer cases were identified over a median follow-up of 5.0 years. After adjusting for potential confounders, individuals with clinically significant depressive symptoms (10-item Center for Epidemiologic Studies Depression Scale score ≥10) had a 19.3% higher risk of developing cancer compared to those without (hazard ratio = 1.193, 95% confidence interval = 0.905-1.572, P = .210). This association persisted when categorized by the severity of depressive symptoms. Our findings suggest that depressive symptoms showed a nonsignificant trend toward increased risk of incident cancer in middle-aged and older Chinese adults. This underscores the importance of mental health screening and intervention in this population, potentially as part of a comprehensive strategy for cancer prevention. Further research is needed to elucidate the underlying mechanisms and to develop targeted interventions.
