“…Another Singaporean study using the same definition of hypertension as we did, although not limited to the elderly, did report a prevalence of hypertension among those aged X65 years that was comparable with our findings. 6 Similar to previous studies, 14,[16][17][18]20,22,23,25,26 we observed hypertension to be associated with age, higher BMI and diabetes. We also observed elderly men to be at a higher risk of hypertension, whereas previous studies have reported either no association with gender, 17,20 or a higher risk for women.…”

“…36 The prevalence of hypertension and its awareness, treatment and control in studies conducted exclusively among the elderly and using our criteria for defining hypertension is given in Table 5. 14,15,17,[19][20][21][22][23][24][25][26][27] Although most of these studies reported a lower prevalence of hypertension 17,20,[22][23][24][25]27 than what we observed (73.9%), some Hypertension among elderly Singaporeans R Malhotra et al reported a similar prevalence 14,19,21,23,26 or, in one study, 15 an even higher prevalence. Other than differences in the BP measurement instrument (manual or electronic) and number of readings (two or three) used for defining SBP and DBP, the variation could also reflect differences in demographic (for example, age, gender, ethnicity) and lifestyle (for example, diet, physical activity) profiles and in economic development across countries (prevalence is usually higher in more developed economies 38 ).…”

“…4,6 Recognizing the elderly as an at-risk population, studies in various countries have documented the prevalence and correlates of hypertension and of awareness, treatment and control of hypertension among the elderly. [14][15][16][17][18][19][20][21][22][23][24][25][26][27] These studies suggest considerable heterogeneity for the prevalence of these conditions across elderly subgroups, defined by socio-demographic or health characteristics. Furthermore, neither the prevalence nor the identified correlates are uniform across countries.…”

Prevalence, awareness, treatment and control of hypertension in the elderly population of Singapore

et al. 2010

A comprehensive picture of the management of hypertension in the increasing elderly population in Singapore is lacking. In this study, we assess the prevalence and correlates of hypertension and of awareness, treatment and control of hypertension among 4494 elderly Singaporeans (X60 years) participating in a recent representative survey. The weighted prevalences of hypertension (systolic blood pressure X140 mm Hg or diastolic blood pressure X90 mm Hg or current use of antihypertension medication) and of awareness, treatment and control of hypertension were assessed. We assessed the extent of association of these outcomes with socio-demographic (age, gender, ethnicity, education, housing type, living arrangement and social participation) and health (body mass, diabetes and cognitive status) variables using multivariable logistic regression. Nearly three-fourths (73.9%) of participants were found to have hypertension. Of this number, 30.8% were unaware that they had hypertension, 32.0% were not being treated for the disease and 75.9% had suboptimal control of their blood pressure. Among those aware of their hypertension, only 1.9% were untreated. However, nearly two-thirds (64.5%) of treated hypertensives had suboptimal control. Age, gender, ethnicity, education, housing type, body mass and diabetes were significantly correlated with lack of awareness, treatment and control of hypertension. Although the specific 'at-risk' subgroups varied by the outcome, men and Malays had consistently higher odds for all three unfavorable outcomes. There is a need to improve awareness, treatment and especially control of hypertension among elderly Singaporeans. Primary and secondary prevention efforts targeting the elderly and their primary health-care providers are called for, as are regular data collection efforts based on representative samples.

Intraocular Pressure Measured With a Noncontact Tonometer in an Elderly Chinese Population

et al. 2005

View full text Add to dashboard Cite

To determine the distribution of intraocular pressure (IOP) as measured by a noncontact tonometer (NCT) and risk factors responsible for ocular hypertension in elderly Chinese people. Design: Population-based study of randomly sampled Chinese people 65 years and older in Shihpai, Taipei, Taiwan. Main Outcome Measures: Participants completed an interview and underwent a physical examination and a standardized ophthalmic examination, including IOP measurement with the NCT. People with a history of glaucoma were excluded. Risk factors were assessed using multivariate regression analysis. Results: Of 1361 study participants examined, 1292 (95.4%) had no history of glaucoma and were therefore included in the study. Their mean±SD IOP was 12.9±3.1 mm Hg. The IOP decreased significantly (PϽ.001) with age, changing from 13.3±3.0 mm Hg in participants aged 65 to 69 years to 11.6±2.8 mm Hg in those 80 years and older. Women had significantly higher IOP than men (PϽ.001). In the multivariate regression analysis, decreasing age, female sex, increasing systolic blood pressure, a history of diabetes, and alcohol drinking were significantly associated with increasing IOP. Conclusions: The distribution of IOP in elderly Chinese people is similar to that found in other East Asian people, with a negative age-IOP relationship. The mean IOP values in this elderly Chinese population were lower than in white people but higher than in Japanese people in similarly aged groups. Establishing the epidemiologic characteristics of IOP with the NCT is important for the mass screening of ocular hypertension.

Hypertension generally requires the use of a combination therapy to achieve the satisfactory control of blood pressure. A traditional Chinese herb, Danshen (Salvia miltiorrhiza), has been shown to have cardioprotective effects in animals and humans. The study investigated the add-on effect of Fufang Danshen extract capsule in Taiwanese hypertensive patients with uncontrolled blood pressure. This was a double-blind, placebo-controlled, randomized, single-center study clinical trial. Fifty-five patients with uncontrolled mild to moderate hypertension were enrolled under current conventional antihypertensive treatment, randomized equally to receive a Fufang Danshen capsule (formula mixture) 1000 mg twice-daily or a placebo capsule for 12 weeks. Primary endpoints were the control rate and the response rate. By ITT analysis at week 12, the control rates were 25.5% in the Fufang Danshen group and 7.3% in the control group (p = 0.016). The response rates were 45.6% in the Fufang Danshen group and 38.2% in the placebo group (p = 0.946). A significant reduction of systolic blood pressure at week 12 was noted in the Fufang Danshen group compared with the placebo group (13.8 vs 4.2 mmHg, p = 0.005). A decrease of pulse rate was also noted in the Fufang Danshen group (- 3.2 vs +2.7/min, p = 0.027). Adverse events were not statistically different between the two groups. It was concluded that Fufang Danshen (Salvia miltiorrhiza) extract reduced systolic blood pressure and pulse rate, and was well tolerated in patients with hypertension.
