A systematic review and meta-analysis of the effectiveness of hypertension interventions in faith-based organisation settings.

Background: Hypertension is the global, leading cause of mortality and is the main risk factor for cardiovascular disease. Community-based partnerships can provide cost-saving ways of delivering effective blood pressure (BP) interventions to people in resource-poor settings. Faith-based organisations (FBOs) prove important potential health partners, given their reach and community standing. This potential is especially strong in hard-to-reach, socio-economically marginalised communities. This systematic review explores the state of the evidence of FBO-based interventions on BP management, with a focus on randomised controlled trials (RCTs) and cluster RCTs (C-RCTs). Methods: Seven academic databases (English = 5, Chinese = 2) and grey literature were searched for C-/RCTs of community-based interventions in FBO settings. Only studies with pre- and post-intervention BP measures were kept for analysis. Random effects models were developed using restricted maximum likelihood estimation (REML) to estimate the population average mean change and 95% confidence interval (CI) of both systolic and diastolic blood pressure (SBP and DBP). The overall heterogeneity was assessed by successively adding studies and recording changes in heterogeneity. Prediction intervals were generated to capture the spread of the pooled effect across study settings. Results: Of the 19 055 titles identified, only 11 studies of fair to good quality were kept for meta-analysis. Non-significant, average mean differences between baseline and follow-up for the intervention and control groups were found for both SBP (0.78 mm of mercury (mmHg) (95% CI = 2.11-0.55)) and DBP (-0.20 mm Hg (95% CI = -1.16 to 0.75)). Subgroup analysis revealed a significant reduction in SBP of -6.23 mm Hg (95% CI = -11.21 to -1.25) for populations with mean baseline SBP of ≥140 mm Hg. Conclusions: The results support the potential of FBO-based interventions in lowering SBP in clinically hypertensive populations. However, the limited evidence was concentrated primarily in Christian communities in the US More research is needed to understand the implications of such interventions in producing clinically meaningful long-term effects in a variety of settings. Further research can illuminate factors that affect success and potential expansion to sites outside the US as well as non-Christian FBOs. Current evidence is inadequate to evaluate the potential of FBO-based interventions in preventing hypertension in non-hypertensive populations. Intervention effects in non-hypertensive population might be better reflected through intermediate outcomes.

Point-of-Care Ultrasound of Post-acute COVID-19 Syndrome: A Prospective Cohort Study.

Introduction Acute COVID-19 patients can suffer from chronic symptoms known as post-acute sequelae of SARS-CoV-2 infection (PASC). Point-of-care ultrasound (POCUS) is established in acute COVID, but its utility in PASC is unclear. We sought to determine the incidence of cardiac and pulmonary abnormalities with POCUS in patients with PASC in a COVID-19 recovery clinic. Methods This prospective cohort study included adults (>18 years old) presenting with cardiopulmonary symptoms to the COVID-19 recovery clinic. A lung ultrasound and standard bedside echocardiogram were performed by ultrasound-trained physicians. Images were interpreted in real time by the performing sonographer and independently by a blinded ultrasound faculty member. Discrepancies in interpretation were addressed by consensus review. A modified Soldati score was calculated by the sum of the scores in each of the 12 lung zones, with each zone score ranging from 0 to 3 (maximum score of 36). The score was then compared to clinical outcomes and outpatient testing.  Results Between April and July 2021, 41 patients received POCUS examinations, with 24 of those included in the study. In all, 15 out of 24 (62.5%) had a normal lung ultrasound. Of the nine subjects with lung abnormalities, the median modified Soldati score was 2. Three patients had trivial pericardial effusions, and all had normal left and right ventricular size and function. Conclusion The majority (62.5%) of patients presenting to the PASC clinic had a normal pulmonary ultrasound, and the vast majority (87.5%) had normal cardiac ultrasounds. These findings suggest that cardiopulmonary symptoms in PASC may be from etiologies not well evaluated by POCUS.

Chronic Kidney Disease of Non-traditional Etiology in a Young Man From Central America: Geography, Poverty, and Uncertain Pathophysiology Create a Formidable Medical Challenge.

A man in his early 20s with kidney biopsy-confirmed focal segmental glomerulosclerosis (FSGS) was admitted with one month of nausea and vomiting, intermittent episodes of confusion, shortness of breath, and dysuria. He reported that many people from his native village in Central America, where he harvested sugarcane as a child, have died from kidney disease, including his father and cousin. He believed the source of disease to be agrochemicals found in the village's water supply. Although FSGS would be a rare manifestation, the patient's risk factors strongly suggested chronic kidney disease of unknown etiology (CKDu) - also known as Mesoamerican nephropathy (MeN) - a phenomenon he had never previously heard of. He took lisinopril for the last six years to manage his kidney disease. Due to uremic symptoms and abnormal electrolytes, he was initiated on hemodialysis.

A Thrombotic Thrombocytopenic Purpura-Like Syndrome in HIV and Streptococcus pneumoniae Meningitis.

Thrombotic thrombocytopenic purpura (TTP) is a disorder characterized by the formation of diffuse thromboses in small blood vessels, which can result in neurological and renal impairment, fever, and purpura, among additional sequelae. TTP-like syndromes are disease processes that have similar signs and symptoms as TTP but without a severe deficiency in ADAMTS13 levels. We present a case of a young male with advanced human immunodeficiency virus (HIV) and Streptococcus pneumoniae meningitis presenting with a thrombotic microangiopathy (TMA). Although his ADAMTS13 level was not suggestive of TTP, at 54.4% (normal low ADAMTS13: >66.8% activity; severe ADAMTS13 deficiency: ≤10% activity), he improved only after plasmapheresis was initiated, supporting a diagnosis of a TTP-like syndrome likely due to his streptococcal meningitis. We discuss the importance of treating patients with TTP-like syndromes and advanced HIV with highly active antiretroviral therapy (HAART). We also highlight the increased prevalence of TMA and TTP among HIV patients and that many of these patients do not have a severe deficiency in levels of serum ADAMTS13.

Systematic Review Estimating the Burden of Dementia in the Latin America and Caribbean Region: A Bayesian Approach.

Background: The global burden of dementia has increasingly shifted to low- and middle-income regions that lack essential data for monitoring epidemiological progression, and policy and planning support. Drawing upon data that have emerged since the last known estimates published in 2015, this study aims to update dementia estimates in the Latin America and Caribbean (LAC) region for the years 2020, 2030, and 2050 through the application of a recently validated Bayesian approach for disease estimates useful when data sources are scarce. Methods: A comprehensive parallel systematic review of PubMed, EMBASE, PsycINFO, Global Health, and LILACS was conducted to identify prospective population-based epidemiological studies on dementia published in English from 2013 to 2018 in LAC. English and non-English data cited by a recent review on dementia estimates in LAC were also examined for additional data. A Bayesian normal-normal hierarchical model (NNHM) was developed to estimate age-specific and age-adjusted dementia prevalence in people aged 60+. Using age-specific population projections from the UN, the total number of people affected by dementia for the years 2020, 2030, and 2050 were estimated. Results: 1,414 studies were identified, of which only 7 met the inclusion criteria. The studies had 7,684 participants and 1,191 dementia cases. The age-standardized prevalence of all forms of dementia in LAC was 8% (95% CI: 5-11.5%) in people aged 60+. The estimated prevalence varied with age, increasing from 2.5% (95% CI: 0.08-4.0%) in the 60-69 age group, to 9.4% (95% CI: 5.4-13.2%) in the 70-79 age group and 28.9% (95% CI: 20.3-37.2%) in the ≥80 age group. The number of people age 60 and older living with dementia in LAC in 2020 was estimated at 6.86 (95% CI: 4.3-9.8) million, 9.94 (95% CI: 6.16-14.15) million in 2030, and 19.33 (95% CI: 12.3-13.6) million in 2050. Conclusion: We project an upward disease trajectory for dementia in LAC countries. The projection is likely an underestimation of the true dementia burden given the underrepresentation of rural and socio-economically deprived populations. More research is urgently needed to improve the accuracy of disease estimates, guide clinicians to improve evaluations for earlier recognition of dementia, and support the development of effective policies for improving dementia prevention, diagnosis and clinical management in LAC's diverse and aging communities.

Construction of an area-deprivation index for 2869 counties in China: a census-based approach.

BACKGROUND: A paucity of data has made it challenging to construct a deprivation index at the lowest administrative, or county, level in China. An index is required to guide health equity monitoring and resource allocation to regions of greatest need. This study used China's 2010 census data to construct a county-level area-deprivation index (CADI). METHODS: Data for 2869 counties from China's 2010 census were used to generate a CADI. Eleven indicators across four domains of deprivation were selected for principal component analysis with standardisation of the first principal component. Sensitivity analysis was used to test whether the population size and weighting method affected the index's robustness. Deprived counties identified by the CADI were then compared with China's official list of poverty-stricken counties. RESULTS: The first principal component explained 60.38% of the total variation in the deprivation indicators. The CADI ranged from the least deprived value of -2.71 to the most deprived value of 2.92, with SD of 1. The CADI was found to be robust against county-level population size and different weighting methods. When compared with the official list of poverty-stricken counties in China, the deprived counties identified by the CADI were found to be even more deprived. CONCLUSION: Constructing a robust area-deprivation index for China at the county level based on population census data is feasible. The CADI is a potential policy tool to identify China's most deprived areas. In the future, it may support health equity monitoring and comparison at the national and subnational levels.

Systematic review estimating the burden of dementia in the WHO Southeast Asia Region using Bayesian and frequentist approaches.

BACKGROUND: Rapid increase in life expectancy in low- and middle-income countries including the World Health Organization's Southeast Asia Region (SEAR) has resulted in an increase in the global burden of dementia, which is expected to become a leading cause of morbidity. Accurate burden estimates are key for informing policy and planning. Given the paucity of data, estimates were developed using both a Bayesian methodology and as well as a traditional frequentist approach to gain better insights into methodological approaches for disease burden estimates. METHODS: Seven databases were searched for studies published between 2010-2018 regarding dementia prevalence in SEAR, generating 8 relevant articles. A random-effects model (REM) and a Bayesian normal-normal hierarchical model (NNHM) were used to obtain the pooled prevalence estimate of dementia for people aged 60 and above in SEAR. The latter model was also developed to estimate age-specific dementia prevalence. Using UN population estimates for SEAR, total and age-specific projections of the burden of dementia in 2015, 2020 and 2030 were calculated. RESULTS: The prevalence of dementia in SEAR was found to be 3% (95% confidence interval (CI) = 2-6%) in those above age 60 based on REM, and 3.1% (95% credible interval = 1.5-5.0%) based on the NNHM. The estimated prevalence varies with age, increasing from 1.6% (95% credible interval = 0.8-2.5%) in people aged 60-69 to 12.4% (95% credible interval = 5.6-20%) in people above the age of 80. The risk of developing dementia increased exponentially with age. The number of people living with dementia in SEAR in 2015 was estimated at 5.51 million (95% credible interval = 2.66-8.82), with projections of 6.66 million (95% credible interval = 3.21-10.7) in 2020 and 9.6 million (95% credible interval = 4.62-15.36) in 2030. CONCLUSION: The burden of dementia in SEAR is substantial and will continue to increase rapidly by 2030. The lack of research focusing on dementia in SEAR points to a significant under-recognition of this disease. The projected rise in dementia cases in the future should prompt urgent governmental response to address this growing public health issue. We also argue that given the overall paucity of data for the region, the Bayesian approach offers a promising methodology for improved estimates of disease prevalence and burden and should continue to be explored.

Beijing's diagnosis-related group payment reform pilot: Impact on quality of acute myocardial infarction care.

In 2012, China's first diagnosis-related group (DRG) payment system was piloted in Beijing. This study explored whether this payment pilot improved quality and reduced costs of acute myocardial infarction (AMI) care in hospitals implementing DRG payment as compared to control hospitals. A difference-in-difference study design was used with regression and considered several quality indicators including aspirin at arrival, aspirin at discharge, ß-blocker at arrival, ß-blocker at discharge, statin at discharge, in-hospital mortality, and 30-day readmission rates. DRG payment mechanisms without specific mechanisms to promote care quality did not improve quality of AMI care. Future studies should study the impact of cost control mechanisms together with quality improvement efforts to assess how quality of care may be improved within the Chinese healthcare system. These lessons would be helpful to share with lower-middle-income countries undergoing rapid development that are transitioning to a significantly higher burden of non-communicable diseases.

Acceptability and willingness of HIV pre-exposure prophylaxis amongst female sex workers in China.

HIV pre-exposure prophylaxis (PrEP) is a highly effective prevention method. It is an attractive self-initiated approach to reduce the spread of HIV amongst female sex workers (FSW). PrEP, however, has not yet achieved its potential to reduce HIV infections partially due to a general lack of awareness from women who may benefit. Aims of this cross-sectional study of 1,466 FSW in China were to understand: levels of awareness of and willingness to use PrEP among female sex workers (FSW) in China, and factors contributing to willingness to use PrEP. We found that awareness (10.2%) and willingness (35.5%) to use PrEP were low in our survey areas. Low PrEP willingness is likely reflective of the overall poor knowledge and understanding of HIV risk and prevention. FSW that demonstrated greater HIV knowledge through having been tested or having greater decision-making involvement in condom use were more willing to use PrEP. Study findings may be used to inform future HIV prevention activities, including possible use of PrEP among FSW at higher risk of incident HIV infection in China.

Prevalence of epilepsy in China between 1990 and 2015: A systematic review and meta-analysis.

BACKGROUND: Epilepsy is a major neurological disorder that affects approximately 65 million people worldwide. Globally, the burden of epilepsy is not evenly distributed, with more than 80% of sufferers residing in low- and middle-income countries. This study estimates the burden of epilepsy in mainland China from 1990 to 2015 and explores the variations of burden by age and gender. METHODS: We conducted a systematic review of the peer-reviewed literature from 1990 to 2015 using Chinese and English academic databases (CNKI, WanFang, VIP and PubMed) to identify population-based prospective studies on the prevalence of epilepsy in mainland Chinese. Multilevel mixed-effects logistic regression was used to estimate the prevalence of lifetime epilepsy (LTE), and restricted cubic regression splines were applied to model the functional forms of the non-linear effects of age and LTE prevalence. Random-effect meta-analysis was used to obtain the pooled prevalence of 1-year active epilepsy (AE), 2-year AE and 5-year AE separately. To estimate the number of people with LTE and AE in the years 1990, 2000, and 2015, LTE and AE prevalence were multiplied by the total population of mainland China of the corresponding year. FINDINGS: Analyses were conducted using 39 prevalence studies that met the inclusion criteria and comprised 77 separate data points (37 on LTE, 16 on 1-year AE, 12 on 2-year AE and 12 on 5-year AE). In 1990, the prevalence of LTE ranged from 1.31‰ (95% CI = 0.85-2.00) in the 0-4 age group to 2.42‰ (95% confidence interval CI = 1.60-3.65) in the 30-34 age group. By 2015, the LTE prevalence had increased to 4.57‰ (95% CI = 2.52-8.27) in the 0-4 group and 8.43‰ (95% CI = 4.71-15.04) in the 30-34 group. Over the 25-year period, the overall prevalence of LTE had steadily increased by 259%, from 1.99‰ (95% CI = 1.31-3.02) in 1990 to 7.15‰ (95% CI = 3.98-12.82) in 2015. The rates of increase were similar across the whole age spectrum, fluctuating around 250%. Between 1990 and 2015, the total number of people with LTE in mainland China increased by 328%, from 2.30 million (95% CI = 1.51-3.49) in 1990 to 9.84 million (95% CI = 5.48-17.64) in 2015. The pooled 1-year, 2-year, and 5-year AE prevalence were 3.79‰ (95% CI = 3.31-4.34), 4.08‰ (95% CI = 3.41-4.89) and 4.19‰ (95% CI = 3.42-5.15). CONCLUSIONS: The burden of LTE in China has increased substantially between 1990 and 2015, with the prevalence of LTE having more than doubled and the number of people with LTE more than tripled. The large amount of AE cases in China calls for optimal management and treatment. More high-quality epidemiological studies on LTE and AE prevalence are still needed.

Prevalence of chronic obstructive pulmonary disease (COPD) in China in 1990 and 2010.

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is set to become the third most frequent cause of death and also the third largest cause of global morbidity by 2020. In China, where the population is aging rapidly, COPD has become one of the leading causes of disability and a large economic burden. An epidemiological assessment of the COPD in China is required, with a focus on the number of cases living with disease, main determinants of the disease and time trends. METHODS: We systematically searched large Chinese bibliographic databases and English databases to identify spirometry-based epidemiological studies of the prevalence of COPD in China diagnosed according to GOLD criteria. We estimated age- and gender-specific prevalence of COPD using a multilevel mixed-effect logistic regression. We also presented the time trends of COPD between 1990 and 2010 by age, gender and setting (urban vs rural). FINDINGS: In 1990, the prevalence of COPD ranged from 0.49% (95% CI = 0.29-0.85) in <20 years group to 20.95% (95% CI = 14.04-27.04) in> = 80 years group, and the crude prevalence for China was 2.70% (95% CI = 1.86-3.51). In 2010, the prevalence in <20 years was 0.55% (95% CI = 0.37-1.04) and in> = 80 years was 22.89% (95% CI = 18.13-28.96), with the crude prevalence for China of 3.84% (95% CI = 3.30-4.77). The COPD prevalence in males was about two-fold higher than in females, and it increased with increasing age. Between 1990-2010, the total number of Chinese people living with COPD increased by 66.73%, from 30.90 million (95% CI = 21.28-40.02) in 1990 to 51.52 million (95% CI = 44.26-63.93) in 2010. This increase was most striking in middle age, and greater in females than in males from 30 years up to 64 years. Our estimates, which used an independent approach to acquiring data and development of analytical methods, and were based on a more complete data set, are remarkably similar to those produced recently by the GBD 2013 collaboration, differing by only about 5% in the estimated number of COPD cases in 1990 and by 1% in 2010. CONCLUSIONS: COPD is a highly prevalent disease in China and its importance is growing steadily. The number of people living with COPD has increased substantially between 1990 and 2010. COPD is more frequent in males and in rural areas. Optimised primary and secondary prevention and treatment is urgently needed to counter this growing trend. Improved epidemiological studies will be required to assist development of more effective strategies of prevention and treatment of COPD in China in the next decade and beyond.

Differences in risk behaviours and HIV/STI prevalence between low-fee and medium-fee female sex workers in three provinces in China.

OBJECTIVES: To better understand risk behaviours and factors associated with low-fee female sex workers (FSW) and support HIV/sexually transmitted infections (STI) epidemic control among this key population in China. METHODS: A cross-sectional study using convenience sampling to recruit 1487 eligible low-fee and medium-fee FSW was conducted in 2012 in three provinces. The participants were interviewed using a structured questionnaire and tested for HIV-1, herpes simplex virus (HSV)-2 and syphilis antibody. Log-binomial modelling was used to estimate prevalence ratios (PR) and examine factors associated with low-fee sex work. RESULTS: Prevalence of HIV-1, syphilis and HSV-2 antibody positive were 0.5%, 4.8% and 27.8%, respectively. Low-fee FSW were more likely to have HSV-2 infection (adjusted prevalence ratio (APR)=1.3, 95% CI 1.1 to 1.7), but not more likely to have HIV-1 and syphilis infection compared with medium-fee FSW. Compared with medium-fee FSW, low-fee FSW were more likely to be ≥35 years of age (APR=2.1, 95% CI 1.3 to 3.6), engage in sex work ≥6 days/per week (APR=1.7, 95% CI 1.2 to 2.6), have ≥3 clients per day (APR=2.2, 95% CI 1.5 to 3.3), have clients decide condom use (APR=1.6, 95% CI 1.1 to 2.3), fail to persuade clients to use condoms (APR=1.6, 95% CI 1.1 to 2.6), express willingness to have unprotected sex in return for receipt of a higher fee (APR=1.8, 95% CI 1.2 to 2.8), have had genital symptoms in the past year (APR=1.4, 95% CI 1.1 to 1.8) and have migrated from another city. CONCLUSIONS: Low-fee FSW in China have unique risks for acquiring HIV/STI, in part due to greater economic pressures. Tailored interventions targeting low-fee FSW and incorporating their prevailing perception of HIV/STI risks and condom use negotiation challenges that they face are urgently needed.

Payment Reform Pilot In Beijing Hospitals Reduced Expenditures And Out-Of-Pocket Payments Per Admission.

In 2009 China announced plans to reform provider payment methods at public hospitals by moving from fee-for-service (FFS) to prospective and aggregated payment methods that included the use of diagnosis-related groups (DRGs) to control health expenditures. In October 2011 health policy makers selected six Beijing hospitals to pioneer the first DRG payment system in China. We used hospital discharge data from the six pilot hospitals and eight other hospitals, which continued to use FFS and served as controls, from the period 2010-12 to evaluate the pilot's impact on cost containment through a difference-in-differences methods design. Our study found that DRG payment led to reductions of 6.2 percent and 10.5 percent, respectively, in health expenditures and out-of-pocket payments by patients per hospital admission. We did not find evidence of any increase in hospital readmission rates or cost shifting from cases eligible for DRG payment to ineligible cases. However, hospitals continued to use FFS payments for patients who were older and had more complications than other patients, which reduced the effectiveness of payment reform. Continuous evidence-based monitoring and evaluation linked with adequate management systems are necessary to enable China and other low- and middle-income countries to broadly implement DRGs and refine payment systems.

Is occupation a good predictor of self-rated health in China?

BACKGROUND: China's rapidly changing economic landscape has led to widening social inequalities. Occupational status in terms of occupational type and prestige may reflect these socio-structural shifts of social position and be more predictive of self-rated health status than income and education, which may only reflect more gradual acquisitions of social status over time. The goals of this study were to understand the role of occupational status in predicting self-rated health, which is well known to be associated with long-term mortality, as well as compare the occupational status to the other major socioeconomic indicators of income and education. METHODS: Data from the 2010 baseline surveys of the China Family Panel Studies, which utilized multi-stage probability sampling with implicit stratification was used. Logistic regression was used to examine the relationship of various socioeconomic indicators (i.e. occupational status, income, and education) with self-rated health as the primary outcome of interest. A series of models considered the associations of occupational category or occupational prestige with self-rated health. RESULTS: The final sample consisted of 14,367 employed adults aged 18-60, which was nationally representative of working adults in China. We found that occupation was not a major predictor of self-rated health in China when age, ethnicity, location, marital status, physical and mental health status were controlled for, with the exception of women working in lower grade management and professional jobs (OR = 1.82, 95% CI: 1.03-3.22). In comparison, income followed by education exhibited greater association with self-rated health. The highest income group had the least probability to report poor health (In men: OR = 0.30, 95% CI: 0.21-0.43. In women: OR = 0.44, 95% CI: 0.26-0.73). People educated with junior high school had better self-rated health than those with primary and below education level (In men: OR = 0.62, 95% CI: 0.50-0.75. In women: OR = 0.53, 95% CI: 0.42-0.68). Income, education and occupation were correlated with each other. CONCLUSIONS: Within the context of rapid societal changes in China, income and its implications for greater healthcare access and benefits had the greatest association with self-rated health followed by education. Occupational status was not associated. Occupational categories and prestige should be better adapted to reflect China's unique sociopolitical and historical context.

Review of HIV and other sexually transmitted infections among female sex workers in China.

Female sex workers (FSW) are at greater risk for HIV and STIs. A systematic literature review of HIV and STI prevalence and incidence data for FSW in China was conducted to assess current trends. Studies between 1996 and 2010 detailing seroprevalence or incidence data, other laboratory-based tests, and clinical diagnoses of infections among FSW were reviewed. Select articles from Chinese literature around street-based and drug-abusing FSW were also reviewed. Results revealed high median prevalence for a variety of STIs among FSW: active syphilis range 0.8-12.5% (median = 6.9%), herpes range 29.7-70.8% (median = 56.2%), chlamydia range 3.9-58.6% (median = 25.7%), gonorrhea range 2.0-85.4% (median = 16.4%), and trichomoniasis range 7.1-43.2% (median = 12.5%). HIV prevalence has remained relatively low and stable with a range of 0-10.3% (median = 0.6%), with the exception of higher prevalence in several areas of Yunnan and some areas of Guangxi. The FSW who are injecting drug users may be at even greater risk for HIV infection with 12-49% found to be HIV positive and 7-25% self-reporting positive status. A number of gaps in the literature remain, especially in the number of studies that detail prevalence confirmed by laboratory testing or that collect incidence data. Assessment of incidence and prevalence according to sampling methodology appropriate for the population, behavioral risks such as injecting drug use, and diverse venues especially those at the lower end are needed. Theory-based interventions to reduce the incidence and prevalence of HIV/STIs need to be piloted with successful models scaled-up.

HIV/STI prevention interventions targeting FSWs in China: a systematic literature review.

A rapid increase in heterosexual transmission of HIV and a high prevalence of sexually transmitted infections (STIs) in China signals potential outbreaks of generalized epidemics. A large proportion of heterosexual transmission has been through commercial sex; thus, millions of female sex workers (FSWs) and their clients play a critical role in the country's HIV/STI epidemics. A number of prevention interventions targeting FSWs have been implemented in response to changes in policy toward HIV as well as growing epidemics. This study reviews existing HIV/STI prevention interventions studies targeting FSWs in China. A total of 25 studies (28 articles) were identified from English and Chinese journal databases. Most studies recruited FSWs from entertainment establishments and had small sample sizes of less than 400. A majority employed a simple pre-post design with an open cohort, none applied a randomized controlled trial, and only two studies had a quasi-experimental design. Venue-based knowledge education and condom promotion represented the typical intervention approach. Some adapted internationally validated programs such as Voluntary Counseling and Testing and 100% Condom Use Programs (CUP), but no scale-up data were reported. Significant intervention effects were reported in most studies, especially increases in HIV/STI-related knowledge and condom use rates. Of the nine studies reporting STI rates, the results were mixed; some even reported increased STIs despite higher condom use. We call for more HIV/STI interventions targeting FSWs in China, particularly, interventions with rigorous design and externally validated measures, and more diversity in intervention programs including biomedical and structural interventions as well as innovative intervention delivery. We also advocate that effective intervention programs be translated into sustainable policies and programs that could have an impact on China's HIV and STI epidemics.

The effect of a culturally tailored smoking cessation for Chinese American smokers.

INTRODUCTION: Tobacco use is a serious public health problem among low-income Chinese Americans with limited English proficiency. Chinese men are at high risk for smoking-related morbidity and mortality. We tested the feasibility of a culturally and linguistically sensitive smoking intervention program with combined counseling and pharmacological components for Chinese smokers in New York City; identified factors and techniques that enhance the administration and appropriateness of the intervention program; and examined the overall impact of this program on quit attempts, quit rates, and overall smoking reduction. METHODS: We were guided by the transtheoretical model and used an adapted motivational interviewing (MI) approach. The study involved a randomized sample with pretreatment assessment and multiple follow-up measures. Eligible participants (N = 122) were randomly assigned to intervention (4 individualized counselor-led MI sessions and nicotine replacement therapy [NRT]) or control groups (4 general health education sessions, self-help materials, and NRT). RESULTS: Quit rate at 6 months in the intervention group was 67% versus 32% for the control group, indicating minimal relapse and a highly successful intervention program. Increase in self-efficacy and decease in pros of smoking from baseline to 6-month follow-up were positively associated with smoking cessation. The number of cigarette smoked at baseline was inversely related to smoking cessation. Results indicate that a combined intensive behavioral counseling and pharmacological intervention can reduce smoking substantially. CONCLUSION: The results of this pilot will be used as a basis for a large-scale randomized trial of an intervention with combined culturally and linguistically sensitive MI and NRT components for Chinese and other Asian ethnic groups.
