-Klotho: the hidden link between dietary inflammatory index and accelerated ageing.

Recent studies suggest an association between greater dietary inflammatory index (DII) and higher biological ageing. As -Klotho has been considered as a longevity protein, we examined whether -Klotho plays a role in the association between DII and ageing. We included 3054 participants from the National Health and Nutrition Examination Survey.

Associations of daytime napping and nighttime sleep quality with depressive symptoms in older Chinese: the Guangzhou biobank cohort study.

Background: Poor sleep quality has been linked to depression in older adults, but results of the association between daytime napping and depression remains limited and conflicting. Moreover, whether the association of daytime napping with depression varies by nighttime sleep quality is unclear. Hence, we examined the associations of daytime napping and nighttime sleep quality with depressive symptoms in older Chinese.

Obesity indicators as mediators of the association between age at menopause and blood pressure values.

Having a later age at menopause is associated with having a higher blood pressure (BP) value, but the mediation pathways remain unclear. We quantitatively examined the mediation effects of various obesity indicators using baseline data from phase 4 of the Guangzhou Biobank Cohort Study. The product of coefficients approach and bootstrapping procedures were used to assess the mediation effects of body mass index (BMI), waist circumference (WC), waist-to-hip ratio (WHR) and waist-to-height ratio (WHtR) on the association between age at menopause and BP values.

Association of sleep duration and napping with stroke mortality in older Chinese: A 14-year prospective cohort study of the Guangzhou Biobank Cohort study.

Study Objective: Evidence regarding the association of short sleep duration and napping with stroke remains limited and controversial. We examined the association of sleep duration and napping with risk of stroke mortality in an older Chinese cohort.

Methods: Sleep duration and daytime napping were assessed by face-to-face interview during 2003-2008.
