Our findings suggest that even in cases of relatively low levels of PM10 air pollution (mean annual concentration of 8.3 ± 3.9 μg/m(3)), in addition to the effects on physical health, exposure negatively affects subjective assessments of well-being.
In this study we investigated how different domains of physical activity are associated with depressiveness among women, and how individual variables moderate this relationship. Participants were 956 women, and the data were collected by mail-out survey using the Global Physical Activity Questionnaire, Beck Depression Inventory, and International Personality Item Pool. Lower depressiveness was related to higher leisure time physical activity and to lower occupational physical activity. Income, health problems, level of neuroticism, and extraversion had strong effects on depressiveness, and mediated the link between the leisure and occupational activities and depression.
The composition of centenarians’ gut microbiota has consistently been used as a model for healthy aging studies. However, there is an incomplete understanding of how childhood living conditions and eating habits affect the development and composition of gastrointestinal microbiota in centenarians with good cognitive functions. We compared the gut microbiota as well as the living and eating habits of the oldest-old group and the young people group. The richness and diversity of microbiota and the abundance of hereditary and environmental microbes were higher in people with longevity than young people. People with longevity ate more potatoes and cereal products. In their childhood, they had more exposure to farm animals and did not have sewers compared with young people. Young people’s gut microbiota contained more butyrate-producing bacteria and bacteria that characterized an animal-based Western diet. These results expand our understanding of the effects of childhood environment and diet on the development and stability of the microbiota in people with longevity.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
