Association between housework frequency and cognitive impairment among Chinese older adults: a prospective cohort study based on CLHLS.

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
backgroundHousework is a crucial aspect of instrumental activities of daily living (IADL), essential for maintaining the independence of older adults. This study aims to explore the association between housework frequency and cognitive impairment by incorporating a multidimensional assessment of cognitive impairment risk factors.
methodsThis study utilized data from the Chinese Longitudinal Health and Longevity Survey (CLHLS, 2014-2018), including 2797 older adults, after excluding individuals aged < 65 years, with cognitive impairment or self-reported dementia, or missing education data at baseline, along with those missing Chinese Mini-Mental State Examination (CMMSE) scores at either baseline or follow-up. Cognitive function was assessed using the education-adjusted CMMSE scores, while housework frequency was classified into three levels. Logistic regression models were employed to examine the association of housework frequency with the risk of cognitive impairment, after adjusting for demographics, living habits, and health-related factors. Further adjustments were made sequentially for baseline CMMSE scores and exercise.
resultsThe risk of cognitive impairment was higher among females, those aged 85 and above and non-exercisers. Compared with those who did housework almost everyday, the risk of cognitive impairment was significantly increased among those who did housework sometimes (OR = 1.50; 95% CI, 1.03-2.17), and even higher among those who never did housework (OR = 1.98; 95% CI, 1.49-2.65) after adjusting for demographics, living habits, and health-related factors. Similar associations were obtained after further adjustments sequentially for baseline CMMSE scores and exercise. In addition, hearing loss, social isolation, and non-smoking were identified as risk factors influencing cognitive impairment. No significant interaction effects were found between age and gender with housework frequency.
conclusionsOur study revealed that Chinese older adults who engaged in less housework had a higher risk of cognitive impairment. Doing housework could serve as a cost-effective strategy to reduce this risk in the context of a healthy aging population in China.
