“…We also examined whether age, sex, education, residence and chronic diseases could Another cross-sectional study from India used the Mini-Mental State Examination to assess cognitive impairment and found that indoor air pollution exposure more than doubled the risk of developing cognitive impairment (12). Our results were also consistent with studies about the potentially harmful effects of solid fuel air pollution exposure on physical health (19) and other mental health outcomes (18).…”

“…Although strong evidence links indoor air pollution exposure to higher risk of chronic diseases, low birth weight, and stillbirth (14), the effects of indoor air pollution from solid fuel use on cognition have not been well elaborated. Furthermore, certain subgroups may respond more strongly to indoor air pollution from solid fuel use, such as individuals who are female, aged 65 years and above, have low educational attainment, or have chronic diseases (18).…”

“…We considered an array of environmental covariates, following the existing literature on potential risk factors for mental health, including ambient fine particulate exposure, residential greenness exposure, proximity to the nearest park, polluted fuel use, and use of kitchen range hood (Banay et al 2019; Gu et al 2019; Liu et al 2020; Mukherjee et al 2017; Sarkar et al 2018).…”

BACKGROUND: Recent evidence suggests that window-view and window-ventilation may contribute to mental wellbeing. Compared to their younger counterparts, older adults spend more time at home and have less contact with natural environments due to social isolation and physical decline. However, the association of residential window-opening with depressive symptoms is understudied among older populations. METHODS: We used data from a community-based cohort study conducted in 23 provinces of China including 13,125 adults age 65 years or older (mean age: 83.8 years [SD: 11.1]). We created the window opening index (WOI) as a proxy of window-view and window-ventilation, leveraging relevant data on self-reported frequencies of manual window opening at home. Depressive symptoms were assessed by the 10-item version of the Centre for Epidemiological Studies Depression scale no fewer than 10. We used multivariate logistic regression model to examine the association between window opening and depressive symptoms. RESULTS: In the multivariate logistic regression model controlling for a set of well-designed mood-influencing environmental and individual-level covariates, a protective effect of window opening on depressive symptoms was observed, with 16% lower odds per interquartile increment in WOI (odds ratio: 0.84, 95%-CI: 0.81-0.87). Subgroup analyses indicated that the beneficial effects were more pronounced among those with higher socioeconomic status (higher levels of education, urban residents) and better surrounding environments (lower exposure of ambient fine particular matter, proximity to park, or higher levels of residential greenness). DISCUSSION: The results point to the benefits of well-designed household window-opening environments on the mental health of older populations and suggest a synergistic effect of window-opening and favorable surrounding natural environment.

“…A person is considered to have depressive symptoms if he/she scored less than 10 in the CES-D-10. This threshold of 10 has been widely used in previous studies 36 and well validated in depression measurement in Chinese older populations, regardless of their age and dementia status 37,38 .…”

“…Given that no direct indicator for individual socioeconomic status is provided in the CLHLS, we obtained individually socioeconomic status by using a principal component analysis (PCA) based on four questions (primary occupation before retirement [white collar vs. others], living conditions [living with family members or others, living alone, and living in an institution], retirement earnings, and living expenditure). A compositional score based on the rst component generated from PCA has been suggested to be a quali ed measure of socioeconomic status and has been widely employed in previous studies 36,40 . Social and leisure activity score was calculated by eight kinds of activities (whether a respondent did gardening, practiced Tai Chi, participated in square dance, raised poultry or pets, reading, playing Mahjong or cards, listening to the radio or watching TV, and participating in community social activities) and we scored each activity 1 for 'never', 2 for 'sometimes' 3 for 'almost every day'; The score ranged from 8 to 24 with higher score indicating more leisure activities, and low social and leisure activity level was de ned by the score less than 14.…”

BackgroundExisting research indicates that tea drinking may exert beneficiary effects on mental health. However, associations between different types of tea intake and mental health such as depression are not fully examined. The purpose of this study was to examine the associations of green tea, fermented tea, and flowering tea consumption with depressive symptoms.MethodsWe used data from the 2018 wave of Chinese Longitudinal Healthy Longevity Survey. The type (green, fermented [black, Oolong, white, yellow, dark, and compressed teas], and flower) and frequency of tea consumption and depressive symptoms for 13,115 participants were assessed. We examined the associations between type and frequency of tea intake and depression, controlling for a set of demographic, socioeconomic, psychosocial, behavioral, and health-related variables. ResultsOverall, intake of green tea, fermented tea, and flower tea were all significantly associated with a lower prevalence of depression, independent of other risk factors. Compared with the group for no tea intake, the adjusted ORs for daily green tea, fermented tea, and flower tea intake were 0.85 (0.76-0.95), 0.87 (0.76-0.99), and 0.70 (0.59-0.82), respectively. Linear associations were observed between frequency of all types of tea intake with depressive symptoms (Ps for trend<0.05). The associations of type and frequency of tea intake and depressive symptoms were robust in several sensitivity analyses.ConclusionsAmong Chinese old adults, regularly consumed any type of tea (green, fermented or flower) were less likely to show depressive symptoms, the associations seemed more pronounced among flower tea and green tea drinkers.
