Prevalence and factors associated with mild cognitive impairment among Chinese older adults with depression

Abstract

Aim: Depression and mild cognitive impairment (MCI) are common among older adults. Most of the existing studies were carried out in developed countries, and evidence from developing countries are lacking. In the present study, using a national sample, we aimed to describe the prevalence of MCI and its associated factors among Chinese older adults with depression. Results:The results showed that the prevalence of geriatric depression was 15.9%, and 36.4% of those with depression had MCI. Geriatric depression was found to be significantly associated with MCI after controlling for demographics. Among participants with geriatric depression, female sex, older age, rural or suburban residence, poor physical health status, education level of illiterate or elementary school, having no daily physical activity, and living in Central China or West China were associated with an increased risk of MCI. Conclusions:The present study showed a high prevalence rate of MCI among Chinese older adults with depression. Early screening and treatment for MCI are necessary among people with geriatric depression. Further research and health services innovations are required to address the high prevalence of MCI in this population. Geriatr Gerontol Int 2017; ••: ••-••.

Prevalence of mild cognitive impairment in community-dwelling Chinese populations aged over 55 years: a meta-analysis and systematic review

“…High levels of heterogeneity were found (I 2 > 75%) across the 41 included studies. Of the 38 studies reporting MCI prevalence, three [ 39 , 45 , 59 ] showed significant deviation from the others both in sensitivity tests and visual funnel asymmetry. The Egger’s and Begg’s tests also revealed significant publication bias in the studies ( β = 0.002, p < 0.01).…”

Fine Particulate Matter and Poor Cognitive Function among Chinese Older Adults: Evidence from a Community-Based, 12-Year Prospective Cohort Study

“…", yes or no). In addition, we collected information on medical history, including self-reported diagnoses of diabetes (yes or no), heart disease (yes or no), and respiratory disease (yes or no), hypertension (yes or no based on self-report of a diagnosis by a doctor or physician, or on measured systolic blood pressure ≥140 mmHg or diastolic blood pressure ≥90 mmHg), and disability in activities of daily living (ADL) (yes or no) (Han et al 2019;Li et al 2018;Tervo et al 2004). Blood pressure was measured using a mercury sphygmomanometer after 5 min of rest, and the average value of the two measurements was used for analysis.…”

Prevalence of depressive symptoms in older nursing home residents with intact cognitive function in Taiwan

“…These previous studies have concluded that residents who were younger, were male, had impaired cognitive function, were widowed or had never married, had poor physical function, were illiterate (did not go to any school and did not know how to read or write), experienced pain, experienced loneliness, had difficulty swallowing, had poor perceived health status, lived in an intermediate care facility, or had a shorter length of residency were more prone to have depressive symptoms or depression. Because the evidence shows that cognitive impairment is associated with depressive symptoms or depression (Li et al, ), healthcare professionals might easily overlook the mental health of residents with intact cognitive function.…”
