Use of traditional and complementary medicine as self-care strategies in community health centers
In China, Community Health Centers (CHCs) are major providers of primary care services, but their potential in empowering patients’ self-management capacity has not been assessed. This study aims to describe self-care practice patterns amongst CHC attendees in urban China.
In this cross-sectional quantitative study, 3360 CHC patients from 6 cities within the Pearl Delta Region were sampled using multistage cluster sampling.
Thirty-seven per cent had used with over-the-counter Chinese herbal medicines (OTC CHMs) in the past year and majority of respondents found OTC CHMs effective. OTC CHMs were more popular amongst those who needed to pay out of pocket for CHC services. Less than 10% used vitamins and minerals, and those with a lower socioeconomic background have a higher propensity to consume. Although doubts on their usefulness are expressed, their use by the vulnerable population may reflect barriers to access to conventional health care, cultural affinity, or a defense against negative consequences of illnesses. About 25% performed physical exercise, but the prevalence is lower amongst women and older people. Taiji seems to be an alternative for these populations with promising effectiveness, but overall only 6% of CHC attendees participated.
These results suggest that CHCs should start initiatives in fostering appropriate use of OTC CHM, vitamins, and minerals. Engaging community pharmacists in guiding safe and effective use of OTC CHM amongst the uninsured is essential given their low accessibility to CHC services. Prescription of Taiji instead of physical exercises to women and older people could be more culturally appropriate, and the possibility of including this as part of the CHC services worth further exploration
The effectiveness of Dietary Approaches to Stop Hypertension (DASH) counselling on estimated 10-year cardiovascular risk among patients with newly diagnosed grade 1 hypertension: A randomised clinical trial
A century of trends in adult human height
Being taller is associated with enhanced longevity, and higher education and earnings. We reanalysed 1472 population-based studies, with measurement of height on more than 18.6 million participants to estimate mean height for people born between 1896 and 1996 in 200 countries. The largest gain in adult height over the past century has occurred in South Korean women and Iranian men, who became 20.2 cm (95% credible interval 17.5-22.7) and 16.5 cm (13.3-19.7) taller, respectively. In contrast, there was little change in adult height in some sub-Saharan African countries and in South Asia over the century of analysis. The tallest people over these 100 years are men born in the Netherlands in the last quarter of 20th century, whose average heights surpassed 182.5 cm, and the shortest were women born in Guatemala in 1896 (140.3 cm; 135.8-144.8). The height differential between the tallest and shortest populations was 19-20 cm a century ago, and has remained the same for women and increased for men a century later despite substantial changes in the ranking of countries
Individuals at risk of beta-blocker discontinuation: a cohort study in 19,177 Chinese patients
Purpose:
This cohort study evaluated the factors associated with discontinuation of antihypertensive pharmacotherapy among Chinese patients who were prescribed beta-blockers. We tested the hypothesis that patients’ age, gender, socioeconomic status, clinical settings and the number of comorbidities were significantly associated with the discontinuation of beta-blockers.
Methods:
From a validated clinical database we included all adult patients 18 years or older who were prescribed a beta-blocker in any government primary care clinic in one large territory of Hong Kong during 01 January 2004–30 June 2007. We evaluated the cumulative incidence of drug discontinuation within 180 days of the prescriptions and the factors associated with discontinuation of beta-blockers by multivariable regression analysis.
Results:
From a total of 19,177 eligible patients (mean age = 59.1 years), 20.8% discontinued their medication. Younger patients [aged <50 years; adjusted odds ratios (aOR) 0.41–0.52 for patients aged ≥50 years; p < 0.001], female gender (aOR 0.87 for males, p = 0.001), fee-waivers (aOR 0.78 for fee-payers, p < 0.001), attendances in family medicine specialist clinics (FMSC) (aOR 1.49, p < 0.001) and staff clinics (aOR 2.32, p < 0.001), residence in more urbanized areas (aOR 0.80 for North District, p < 0.001), new visits (aOR 0.55 for follow-up visits, p < 0.001) and absence of concomitant comorbidities (aOR 0.60 for one comorbidity, p < 0.001; aOR 0.56 for two comorbidities, p = 0.002) were positively associated with drug discontinuation.
Conclusions:
Patients who were prescribed beta-blockers with these associated factors should be monitored more closely for antihypertensive drug adherence

Determinants of medication adherence and blood pressure control among hypertensive patients in Hong Kong: a cross-sectional study
Introduction:
Despite effective treatments, suboptimal medication adherence substantially hinders blood pressure (BP) control among hypertensive patients. This study aimed to evaluate the determinants of medication adherence and BP control among hypertensive patients in Hong Kong.
Methods:
A cross-sectional study was conducted. Adult patients aged > 18 years taking at least one type of antihypertensive drugs were recruited from four clinics in Hong Kong. Each patient completed a self-administered questionnaire, including socio-demographic variables and items related to knowledge, illness perception and medication adherence. Medication adherence was measured by the eight-item Morisky Medication Adherence Scale (MMAS-8), with a score > 6 defined as “good adherence”. BP was measured, and optimal control was defined as systolic BP < 140 mm Hg and diastolic BP < 90 mm Hg.
Results:
Among 2445 patients, 55.1% and 52.5% had optimal medication adherence and BP control, respectively. Binary logistic regression analyses were conducted with optimal medication adherence and BP control, respectively, as the outcome variables. Advanced age (adjusted odds ratio [aOR] 1.012, 95% CI 1.002–1.022, p = 0.014), unemployment (aOR for employed 0.782, 95% CI 0.628–0.975, p = 0.029), and good self-perceived health status (aOR 2.155, 95% CI 1.711–2.714, p < 0.001) were associated with good adherence; whereas being married (aOR 1.265, 95% CI 1.038–1.542, p = 0.020) and having no co-morbidity (aOR for morbidity count 0.713, 95% CI 0.639–0.796, p < 0.001) were associated with optimal BP control.
Conclusion:
Evidence-based, adherence-enhancing interventions should be targeted on younger subjects; employed patients; and those with poor self-perceived health status. Patients who are single and those with comorbidities should be closely monitored for their BP control
Pharmacoepidemiological profiles of oral hypoglycemic agents among 28,773 Chinese patients with diabetes
Aims:
This study examined the rates of discontinuation of Oral Hypoglycemic Agents (OHAs) in diabetes patients, and to evaluate the associations between discontinuation of OHAs, socioeconomic status and the number of comorbidities.
Methods:
A cohort study from January 2004 to June 2007 was conducted and followed up through December 2007. We included all primary care clinics in one large territories of Hong Kong involving 28,773 Chinese diabetes patients. Multivariate regression analyses controlled for age, gender, payment status (fee-payers vs. fee waivers; fee-waivers represented those less able to pay for consultation fees and were regarded as having lower socioeconomic status), service type delivered by the clinics, district of residence, visit type (new vs. follow-up), the number of comorbidities and the drug class (sulphonylureas vs. biguanide vs. combination therapy).
Results:
9.9% discontinued their medications within 180 days of their prescriptions. Fee waivers (adjusted odds ratio [AOR] for fee payers = 0.81, 95% C.I. 0.73–0.89, p < 0.001) and the absence of comorbidities (AOR for ≥one morbidity = 0.59–0.62, p < 0.001) were associated with medication discontinuation.
Conclusions:
Diabetes patients with lower ability to pay and without comorbidities were significantly associated with OHAs discontinuation. They should be the target groups for medication counseling programes
The effectiveness of perindopril vs. lisinopril on reducing the incidence of diabetes and renal diseases: A cohort study of 20,252 patients
Background:
Lisinopril and perindopril are two commonly used first-line antihypertensive agents. Few studies compared their effectiveness in reducing the incidence of renal diseases and diabetes.<p></p>
Methods:
Adult patients who received new prescriptions of lisinopril or perindopril from 2001 to 2005 in all public hospitals and clinics in Hong Kong were included, and followed up for at least 2 years. Patients prescribed the angiotensin converting enzyme inhibitors (ACEIs) for < 1 month were excluded. The incidence of admissions due to renal diseases and diabetes was evaluated. We used Cox proportional hazard regression models to assess hospital admissions as the outcome measures, adjusting for age, sex, socioeconomic status, service types, and the proportion of days covered as a measure of medication adherence. The regression models were constructed with propensity score matching to minimize indication biases.<p></p>
Results:
20,252 eligible patients with an average age of 64.5 years (SD 15.0) were included. The admission rates 24 months within the date of index prescription due to renal diseases were 3.1% (lisinopril) and 2.3% (perindopril); and 9.6% (lisinopril) and 7.2% (perindopril) for diabetes. Except for admissions due to diabetes at 6 months, lisinopril users were significantly more likely to be admitted due to renal diseases (adjusted hazard ratios: 1.304 to 1.378) and diabetes (1.146 to 1.231) than perindopril users at all time points.<p></p>
Conclusions:
Patients prescribed different ACEIs might have a different incidence of hospital admissions. Future studies should be conducted to evaluate the comparative effectiveness of different ACEIs on various patient-centered outcomes by head-to-head randomized controlled trials
Duration of initial antihypertensive prescription and medication adherence: A cohort study among 203,259 newly diagnosed hypertensive patients
Background:
Optimal adherence with antihypertensive medications is crucial to prevent hypertension-related complications. This study evaluated whether the duration of initial antihypertensive prescription is associated with better medication adherence in a large sample of Chinese hypertensive patients.
Methods and results:
From a validated clinical database which consists of all patients in the public healthcare sector in Hong Kong, all patients on their first-ever antihypertensive agent from 2001 to 2005 (N = 203,259) were included and followed-up for 12 months (and up to 5 years in separate analyses). The average age was 58.7 years (SD 17.3), and the overall rate of optimal adherence (as measured by having the Proportion of Days Covered ≥ 0.80) was 32.4%. The proportion of patients whose initial prescriptions lasted for ≤ 6 days; 7–14 days; 15–28 days and ≥ 29 days was 23.7%, 24.3%, 15.1% and 37.0%, respectively. The corresponding proportion of optimal adherence was 18.1%, 20.1%, 31.0% and 50.3%. The binary logistic regression analysis showed that after controlling for age, sex, socioeconomic status, service type, drug class, and district of residence, those whose initial prescription was 7–14 days (adjusted odds ratio [AOR] = 1.17, 95% C.I. 1.12–1.22); 15–28 days (AOR = 1.90, 95% C.I. 1.82–1.99) and ≥ 29 days (AOR = 4.13, 95% C.I. 3.96–4.31) were significantly more likely to be adherent than those who were prescribed for ≤ 6 days (all p < 0.001). These findings remained significant in separate analyses where the period of follow-up was extended to 5 years.
Conclusions:
Shorter duration of first antihypertensive prescriptions was associated with poorer medication adherence, and this practice should be avoided if possible
Comparison of three models of ownership of community health centres in China: a qualitative study
Objectives:
Community health centres are the main form of provision of primary care in China. There are three models: government managed, hospital managed and private. Our aim was to describe and compare primary care under the three ownership models.
Methods:
Four aspects of primary care were studied: services, organization, financing and human resources. Interviews were undertaken with 60 managerial and professional staff in 13 community health centres in the Pearl River Delta region in 2010. Three community health centres were selected in the capital city and two were selected from each of the other five cities. Thematic framework analysis was conducted.
Results:
Government-managed community health centres received the largest public funding, followed by hospital-managed community health centres, while private community health centres received the least. Private community health centres were the smallest in scale and provided lower quality public health services compared with the other two models. Patient out-of-pocket costs accounted for the majority of the revenue in all models of community health centres despite improved government funding for preventive services. General challenges such as the shortage of public funding, the exclusion of migrants in the funding for preventive services, low capacity in human resources and the separation of clinical and preventive care in community health centres were identified in all three models of community health centres.
Conclusions:
The ownership and management of a community health centre greatly influence the service it provides. Private community health centres are in a disadvantaged position to deliver high quality clinical and preventive care
