What matters for life satisfaction among the oldest-old? Evidence from China
The world population is aging rapidly and the well-being of older people is of great interest. Therefore, this study investigates the determinants of life satisfaction among the oldest-old (i.e. individuals aged 80 or over) in China.
Materials and methods
We use the 2011/2012 Chinese Longitudinal Healthy Longevity Survey data (n = 6530) for this paper. Logistic regression is used to analyse the effects of socio-demographic, economic, health, instrumental activities of daily living, family and community factors on life satisfaction and depression among the oldest-old in China.
Results
Our analysis confirms the significance of many factors affecting life satisfaction among the oldest-old in China. Factors that are correlated with life satisfaction include respondent’s sex, education, place of residence, self-rated health status, cognitive ability (using mini mental state examination), regular physical examination, perceived relative economic status, access to social security provisions, commercialized insurances, living arrangements, and number of social services available in the community (p<0.05 for all these variables). Although life satisfaction is negatively associated with instrumental activities of daily living (β = -0.068, 95%CI = -.093—.043), and depression (β = -0.463, 95%CI = -.644—.282), the overall effect of self-rated health status is positive (p<0.001). This confirms the primacy of health as the determinant of well-being among the oldest-old.
Conclusions
Majority of the oldest-old in China rated their life satisfaction as good or very good. Our findings show that health and economic status are by far the most significant predictors of life satisfaction. Our finding on the primacy of health and relative income as determinants of well-being among the oldest-old, and the greater influence of self-rated health status over objective health measures is consistent with the findings of many past studies. Our results suggest that efforts should be directed at enhancing family support as well as health and social service provisions in the community to improve life satisfaction of older people
Rett syndrome is associated with altered gut microbiota community
Introduction: Rett syndrome (RTT) is an X-linked neurodevelopmental disorder and the second most common cause of mental retardation in females. Changes in microbiota composition, as observed in other neurological disorders such as autism, may account for several typical symptoms associated to RTT. Indeed, it is shown that a dysbiotic microbiota in gastrointestinal tract may affect the function of the nervous system. The main goal of this preliminary study was to characterize gut microbiota in RTT patients, and to compare it with a healthy control group of female of the same age. Materials and Methods: Eight RTT patients were enrolled at the Child Neuropsychiatry Department of San Paolo Hospital of Milan. Age and sex-matched healthy women (CTR), working at the University of Milan, were recruited. From all subjects we collected stool samples, anthropomet
ricric data and dietary habits. Microbiota characterization was achieved by amplicon sequencing using 16S rRNA regions (V3-V4) genomic region with a Next Generation Sequencing approach on Illumina platform. Concentration of short chain fatty acids (SCFAs) was determined by gas-chromatography analysis. Results: Body mass index (BMI, kg/m2) was 17.4 \ub1 3.9 (mean \ub1 SD) in RTT patients, and 20.9 \ub1 2.2 in control group (p = 0.0284). We did not observe differences in the mean value of Kcal/die (p = 0.43), but RTT diets were characterized by an increase in protein content (p = 0.029) and a lower intake of sugars (p = 0.0035). Microbiota analysis showed a significant lower alpha-diversity in RTT samples compared with control group (chao index and species richness p < 0.0001; shannon index p = 0.0015; and inverse simpson index p = 0.013). The predominant bacterial taxa in both groups were Firmicutes and Bacteroidetes. Although the Firmicutes/Bacteroidetes ratio was similar, at family level Bacteroidaceae were significantly higher in RTT samples (p = 0.0009), whereas Clostridiaceae, Ruminococcaceae and Christensenellaceae were strongly reduced. Desulfovibrio spp., as seen in autistic patients, was found increased in RTT patients (p = 0.0216). We did not find differences in butyrate and acetate concentration (p = 0.1144 and p = 0.6456, respectively) whereas fecal propionate was increased in RTT patients (p = 0.0248). Conclusions: We demonstrated in a small sample of patients that RTT gut microbiota is significantly different from the control group. Our hypothesis is that a dysbiotic gut in RTT patients could result in alterations of SCFAs that can worsen clinical symptoms by interacting at various levels (gut, brain, liver). Understanding critical changes could offer new tools for a diet intervention or probiotics supplementation to improve RTT associated symptoms and, ultimately, psycho-physical wellness
