Female-specific cancers seriously affect physical and psychological health of women worldwide. We aimed to elucidate trends in the age-standardized mortality rates (ASMRs) of breast cancer, cervical cancer, uterine cancer, and ovarian cancer in female populations with different socioeconomic statuses in China and in countries with different Human Development Index (HDI). A longitudinal study was performed using the data of cancer death in China and other 39 countries. The mortality rates were standardized with the Segi’s world population. Trends in the mortalities were exhibited by estimated annual percentage change (EAPC). Pearson correlation was used to assess the association between EAPC and HDI. In mainland China, female breast cancer, cervical cancer, uterine cancer, and ovarian cancer accounted for 6.60 %, 4.21 %, 2.50 %, and 2.02 % of cancer death (n = 1,314,040) in women with 1,220,251,032 person-years, respectively. The ASMRs of cervical cancer (EAPC = 3.87 %, P < 0.001) and ovarian cancer (EAPC = 1.81 %, P < 0.001) increased, that of female breast cancer unchanged, whereas that of uterine cancer was extremely higher and rapidly decreased (EAPC = − 7.65 %, P < 0.001), during 2004–2019. The ASMRs of female breast and ovarian cancers were higher in urban and developed regions than in rural and undeveloped regions, in contrast to cervical and uterine cancers. The ASMRs of female breast and ovarian cancers were lower in China than in other countries, in contrast to uterine cancer. The ASMR of cervical cancer decreased, that of uterine cancer increased, in other countries during 2004–2017. EAPCs for the ASMRs of breast and ovarian cancers were inversely correlated to HDI. The ASMRs of cervical and ovarian cancers increased, in contrast to uterine cancer, in China during socioeconomic transition. Trends in the ASMRs of breast and ovarian cancers were inversely associated with HDI. These data help control female-specific cancers.

INTRODUCTION: Understanding the interplay between genetic factors and lifestyle choices in cognitive health is crucial for enhancing late‐life quality. This study examines the effects of Apolipoprotein E (APOE) genotypes and healthy lifestyles on life expectancy with and without cognitive impairment (CI) in Chinese older adults.METHODS: Data from 6488 participants aged at least 65 in the Chinese Longitudinal Healthy Longevity Survey (CLHLS) were analyzed using continuous‐time three‐state Markov models. Cognitive function was assessed with the Mini‐Mental State Examination (MMSE).RESULTS: APOE ε4 allele carriers had a higher risk of transitioning from cognitively healthy (CH) to impaired, while ε2 carriers had a reduced risk of transitioning from healthy to death. Participants with 4 or 5 healthy lifestyle factors experienced significant protective effects, extending the cognitively healthy life expectancy.DISCUSSION: These findings underscore the importance of promoting healthy lifestyles to delay cognitive decline, regardless of genetic predispositions, particularly in the Asian context.Highlights: Compared with ε3 homozygotes, APOE ε4 carriers in China have a higher risk of transitioning from CH to CI, and APOE ε2 carriers with CH have a lower risk of transitioning to death. Healthy lifestyles can extend life expectancy, primarily extending CH life expectancy. Healthy lifestyles reduce the risk of CI and delay its onset in later life, regardless of APOE genetic risk.

Background and Aim: Any single discrete blood pressure (BP) measurement is not enough to estimate adverse cardiovascular events. We aim to comprehensively investigate the association between BP indicators and stroke. Methods: An observational cohort study was conducted among 2888 Shanghai community-aged residents from 2014 to 2018, and a nested case-control study was designed to identify the association between BP indicators and stroke. In total 415 cases of stroke detected during the study period were selected as the case group and 415 non-stroke subjects, matched with factors of age and gender, were randomly selected from the cohort as control group. Results: Multivariate logistic regression analysis revealed that systolic blood pressure (SBP) (adjusted odds ratio [AOR] 1.02, 95% confidence interval [CI] 1.02– 1.03), pulse pressure (PP) (AOR 1.03, 95% CI 1.02– 1.04), mean arterial pressure (MAP) (AOR1.02, 95% CI 1.01– 1.04) and pulse pressure index (PPI) (AOR 25.68, 95% CI 3.19– 206.90) increased the risk of stroke, respectively. After fitting both BP indicators and covariates, isolated abnormal SBP (AOR 2.55, 95% CI 1.74– 3.72) or PP ≥ 50 mmHg (AOR 1.66, 95% CI 1.08– 2.56) independently increased risk of stroke. Conclusion: Besides SBP, PP and multiple factors, assessment should be taken into account comprehensively for stroke prevention and management.

With greater life expectancy, many more older people will be predisposed to the risk of cognitive impairment, characterised by a decline in memory, attention, language, and other cognitive functions as a transitional state between normal ageing and dementia, which imposed the massive burden of diseases on individuals and their caregivers [1,2]. Therefore, identifying modifiable risk […]

Purpose: The effects of statins on renal outcomes have already been studied in patients with chronic kidney disease (CKD); however, data on the general population are limited. We evaluated the association between statin use and risk of CKD in community-dwelling older people in Shanghai, China. Patients and Methods: This registry-based cohort study was conducted in four communities in four districts in Shanghai. Participants with an estimated glomerular filtration rate (eGFR) ≥ 60 mL/min/1.73 m2 in 2016 were eligible for the study, and new-onset CKD in 2017, 2018, and 2019 was recorded. Poisson generalized linear models were conducted to examine the relationships among statin therapy, dyslipidemia, and CKD; linear mixed-effects models were conducted to examine the relationships between statin therapy and changes in eGFR. All analyses were performed with both conventional adjustment and propensity score-matching methods. Results: Of the study cohort of 2455 participants (41.1% men; average age, 68.06 years), 624 (25.4%) were treated with stains. Two propensity score-matched cohorts of 604 participants each were analyzed (statin users and nonusers). Statin use was significantly associated with a decreased risk of new-onset CKD with hazard ratios (HRs) and 95% confidence intervals (CIs) of 0.73 (0.59 to 0.91) (p< 0.01) in the unmatched cohort and 0.75 (0.59 to 0.97) (p=0.02) in the matched cohort. There were significant differences in the eGFR decline between statin users and nonusers from baseline to 3 years in the unmatched and matched cohorts (both p< 0.05). In addition, both statin users and nonusers with dyslipidemia experienced more new-onset CKD (both p< 0.05). Conclusion: Statin use was significantly associated with a decreased risk of new-onset CKD and a slower decline in eGFR in community-dwelling older people. Meanwhile, dyslipidemia was a risk factor for CKD progression among both statin users and nonusers.
