Methods The study included 349 Chinese men aged 65 and older, grouped into two age categories： group 1 （old） included 163 men aged 65 to 80 years; group 2 （very old） included 186 men aged over 80 years. Blood pressure changes after meals were assessed every 15 min by ambulatory blood pressure monitoring. Symptoms after meal ingestion and after standing up and changes in the baseline condition relative to blood pressure changes were observed continuously. Additional baseline data included body mass index, medical history, and medication use Results The prevalence of PPH was 59.3% overall and was significantly higher in group 2 than group 1 （63.4% vs. 54.6%, P 〈 0.05）. In group 2, the prevalence of PPH after breakfast （33.8%） and lunch （32.1%） were higher than that after supper （20.9%）, P 〈 0.05. Hypertension and age were significant risk factors for PPH （OR = 2.188, 95% CI： 1.134-4.223, P = 0.02; OR = 1.86, 95% CI： 1.112-3.11, P = 0.018, respectively）. In contrast, acarbose use was protective against PPH （OR = 0.4, 95% CI： 0.189-0.847, P = 0.017）. The decrease in blood pres- sure during PPH was 20-40 mmHg and the maximum was 90 mmHg. PPH usually occurred at 30-60 min after a meal and lasted 30-120 rnin. Conclusions These findings demonstrate that the prevalence of PPH in men aged over 80 years is significantly higher than those in men aged 65 to 80 years, and the blood pressure decline is also higher for men aged over 80 years. In addition, hypertension and age were main risk factors for PPH in the older men, which suggest that preventing and treating PPH is worthwhile.展开更多

This study aimed to examine the effects of social network characteristics on the prevalence, awareness, and control of hypertension among older adults. Methods The Korean Social Life, Health, and Aging Project （KSHAP） interviewed 814 〉 60-year-old residents and their spouses from a rural township between December 2011 and March 2012 （response rate： 95%）. We evaluated the data from 595 partici- pants. Multivariate logistic regression models were used to assess the effects of network characteristics on hypertension. Results We ob- served strong sex-specific network effects on the prevalence, awareness, and control of hypertension. Among older women, network density was associated with hypertension awareness [odds ratio （OR）： 2.63, 95% confidence interval （CI）： 1.03 5.37J and control （OR： 1.72; 95% CI 0.94-3.13）. Among older men, large networks were associated with a lower prevalence of hypertension （OR： 0.75; 95% CI： 0.58-0.96）. Compared to older women, older men with coarse networks exhibited better hypertension awareness （OR： 0.37; 95% CI： 0.14-0.95） and control （OR： 0.42; 95% CI： 0.19-0.91 ）. Network size interacted with density for hypertension control （P = 0.051）, with controlled hyperten- sion being associated with large and course networks. Conclusions A large network was associated with a lower risk for hypertension, and a coarse network was associated with hypertension awareness and control among older men. Older women with dense networks were most likely to exhibit hypertension awareness and control.展开更多

Its prevalence depends mainly on age and also on the presence of associ- ated heart disease. In patients without structural heart dis- ease, it is mainly an elderly condition. This is particularly true for advanced IAB, rarely found in global population before 65 years but with prevalence of 8% in the 70＇s and 25% in centenarians,tll When studying prevalence data of this condition, three factors should be taken into account in order to interpret differences that are frequently related with the methodology used （Table 1, Figure 1）.展开更多

METHODS: Bone mineral density (BMD) was measured and questionnaires were taken for 5593 people aged above 40 years in five administrative areas in China selected by the stratified - multi - steps - cluster sampling method. RESULTS: The total prevalence rate of osteoporosis was 16.1%. The prevalence rate among males was 11.5% and among females was 19.9% (P展开更多
