Factors Associated with General Health Screening Participation among Married Immigrant Women in Korea.

Background: The number of married female immigrants living in Korea has been increasing and is expected to increase further. This study was performed to identify factors associated with national general health screening participation among married immigrant women living in South Korea. Methods: The Korean National Health Insurance System’s (NHIS) customized database for the years 2014 and 2015 was used. The targets of this study were women aged 19 years old and above. To identify factors associated with national general health screening participation, the following analyses were employed: frequency, chi-square, simple regression, and multiple regression. Results: A total of 11,213 women were identified in the NHIS database. Overall, 67.4% participated in national general health screenings, lower than the 74.6% participation rate of the entire women’s health screening program. Married immigrant women with a job had higher health screening participation than those without a job (OR = 2.822, p < 0.0001). Age, socioeconomic status, and duration of stay were related to health screening behaviors among employed married immigrant women. Nationality, socioeconomic status, duration of stay, and disease status were associated with general health screening behaviors among unemployed immigrant women. The odds ratios decreased as the length of stay increased, regardless of employment status. Conclusion: The results of this study showed that employment status and duration of stay in Korea are significantly associated with general health screening participation. Accordingly, to improve awareness about health screening and health care disparities, programs promoting health screening participation for socially vulnerable classes, including immigrant women and unemployed women, should be instigated.

Primary Drivers of Willingness to Continue to Participate in Community-Based Health Screening for Chronic Diseases

Background: As the average age of the population continues to rise in the 21st century, chronic illnesses have become the most prominent threats to human health. Research has shown that early screenings for chronic diseases are an effective way of lowering incidence and mortality rates. However, low participation rates for health screening is one of the main challenges for preventive medicine. The objective of this study was to determine the primary drivers which: (1) first motivate people to participate in community-based health screening for chronic diseases; and (2) increase their willingness to continue to participate. Methods: A total of 440 individuals between 30 and 75 years of age were invited to undergo a health screening and then complete an interview questionnaire. Screenings and interviews were conducted in four regions in northern Taiwan. The questionnaire was separated into three sections, which explored sociodemographic differences, drivers of willingness to participate, and willingness to continue to participate respectively. Raw data was analyzed using the statistical software package SPSS (SPSS Inc., Chicago, IL, USA). Main Outcome Measures: Effects of sociodemographic factors on health screening participation rate, drivers of willingness to participate, and willingness to continue to participate. Results: Seventy-three percent of participants responded that they would be willing to continue to join in future health screenings. Notably, elderly people and married people were respectively more likely to participate in preventive health screening than were younger people and people who were single, divorced, separated, or widowed. Level of education was another key driver of willingness to participate in health screening for chronic diseases, as were the concern of relatives/friends and the provision of participation incentives. Discussion: Some of our findings, such as the key drivers of willingness to continue to participate in health screening that we identified, were different from findings of many previous studies conducted in other countries. The current study also found that a higher percentage of participants would be willing to join a similar health screening in the future if the service design is considered in advance and is well-implemented.

Perceived Neighborhood Environment and Its Association with Health Screening and Exercise Participation amongst Low-Income Public Rental Flat Residents in Singapore

Background: In Singapore, an Asian city-state, more than 80% live in public housing. While the majority (90%) own their homes, a needy minority lives in rental flats. Public rental flats are built in the same location as owner-occupied blocks. We evaluated factors associated with perceptions of the neighborhood environment and its association with exercise and health screening participation. Methods: Logistic regression was used to identify associations between perceptions of the neighborhood environment (overall perceived neighborhood disadvantage, safety, and convenience) and sociodemographic factors, as well as exercise and screening participation, amongst residents aged ≥60 years in two Singaporean public housing precincts in 2016. Results: Our response rate was 62.1% (528/800). Staying in a rental flat independently was associated with increased neighborhood disadvantage (adjusted odds ratio, aOR = 1.58, 95%CI = 1.06–2.35). Staying in a stand-alone block (as opposed to staying in a mixed block comprised of both rental and owner-occupied units) was associated with perceptions of a poorer physical environment (aOR = 1.81, 95%CI = 1.22–2.68) and lower perceived proximity to recreational areas (aOR = 1.14, 95%CI = 1.04–1.25). Perceptions of neighborhood disadvantage were independently associated with reduced exercise participation (aOR = 0.67, 95%CI = 0.45–0.98) and reduced participation in diabetes screening (aOR = 0.63, 95%CI = 0.41–0.95). Conclusion: Despite sharing the same built environment, differences in the perception of the neighborhood environment between low-socioeconomic status (SES) and high-SES communities persist. Perceived neighborhood disadvantage is associated with lower participation in regular exercise and diabetes screening.

Irreversible effects of long-term chronic smoking on arterial stiffness: An analysis focusing on ex-smokers among otherwise healthy middle-aged men

ABSTRACTObjective: Smoking is a modifiable cardiovascular risk factor closely related to arterial stiffness (AS). However, data are lacking regarding the chronic effects of smoking on AS, especially in ex-smoker (ES) who faces remnant cardiovascular risk when compared to never-smokers (NS).Methods: Among 1722 health screening participants, we retrospectively evaluated 652 healthy men with different smoking history [240 current smoker (CS) vs. 228 ES vs. 184 NS]. To assess AS, augmentation index (AIx), pulse pressure amplification (PPamp), and carotid-femoral pulse wave velocity (cfPWV) were measured and compared.Results: Baseline characteristics were similar except age and triglyceride level. AIx was lowest in NS, followed by ES, and was highest in CS. PPamp was highest in NS, lowest in CS, and ES was of intermediate level. The differences were more robust after adjustment for baseline covariates (AIx, p = 0.005; PPamp: p = 0.001). On the other hand, no significant intergroup difference was observed for cfPWV in our middle-aged population. With the regression analyses revealing an independent association between smoking duration and AS in ES, subgroup analysis demonstrated that long-term ES (smoking duration ≥20 years) had significantly higher AS than short-term ES (<20 years) and NS, approaching levels comparable to CS (AIx and PPamp: p < 0.0001).Conclusions: Our study demonstrated impaired arterial elastic properties in long-term ES, suggesting that AS caused by chronic smoking might be irreversible even after smoking cessation. Further longitudinal studies are warranted to determine the impacts of past smoking on AS and its clinical relevance.

Factors Associated with Cervical Cancer Screening among Married Female Immigrants with Korean Husbands in South Korea.

Background. The purpose of this study was to identify factors associated with the national cervical cancer screening behaviors of married female immigrants living in South Korea. Methods. The present study dataset was collected by the National Health Insurance Services in 2014–2015. A final study population of 15,935 was considered eligible for inclusion in this study if they met the criteria for participation in the national cervical cancer screening program in 2014–2015. Results. Of the 15,935 subjects, 7837 (49%) participated in cervical cancer screening. Based on the results of the logistic regression analysis of the association between cervical cancer screening behaviors and related factors, the odds ratio (OR) for participation in cervical cancer screening among individuals older than 50 years was the highest (OR: 2.13; 95% confidence interval (CI): 1.82–2.51), and the OR increased as their duration of stay in South Korea decreased. The OR of Chinese women for cervical cancer screening participation was higher than that of non-Chinese women (OR: 1.83; 95% CI: 1.69–1.99). The OR value was 29.4 (95% CI: 25.9–33.3) among those who participated in the general health screening compared with those who did not participate. Conclusions. To improve awareness about cervical cancer screening and reduce disparities in access to healthcare, appropriate programs should be developed to promote cervical cancer screening participation to socially vulnerable classes. Continuous social attention is needed to address these issues and encourage participation in general health screening to improve the rate of cervical cancer screening.

Association of circulating proinflammatory marker, leucine‐rich‐α2‐glycoprotein (LRG1), following metabolic/bariatric surgery

Obesity confers substantial excess risk for morbidity and mortality, especially for type 2 diabetes (T2D). Leucine-rich-α2-glycoprotein 1 (LRG1), a novel proinflammatory factor, was recently reported to be higher in patients with T2D with complications of peripheral arterial disease. Association of LRG1, obesity, and weight loss is unknown. We examined whether plasma LRG1 is associated with obesity in health screening participants and if it predicts future weight loss in morbidly obese patients after metabolic/bariatric surgery. Cohort 1 was a cross-sectional study from a Health Screening program (n=616) in a tertiary hospital. Cohort 2 was a prospective study of morbidly obese patients (n=231) who underwent metabolic/bariatric surgery with follow-up weight measurements. Anthropometric data, baseline fasting glucose, plasma adiponectin, high sensitivity C-reactive protein (HsCRP), and LRG1 were measured. Postsurgery blood, after metabolic/bariatric surgery, were available for LRG1and HsCRP measurements in 57 patients. In the group with highest tertile of LRG1, body mass index (BMI), waist circumference, and HsCRP were significantly higher, while total cholesterol, high-density lipoprotein, low-density lipoprotein, and adiponectin were lower than tertiles 1 and 2. Generalized linear model analysis showed that female gender (P<.0001), non-Chinese ethnicity (P<.019), and higher HsCRP (P<.0001) levels were independent and significant determinants of higher plasma LRG1 levels. After adjustment for age, gender, ethnicity, and baseline BMI, female gender (P=.020), higher presurgery BMI (P=.001), and lower presurgery LRG1 (P=.002) remained statistically significant predictors for greater weight loss. Plasma LRG1 increased significantly [from 28.2 (21.9-36.8) to 34.9 (22.6-49.5)] μg/mL (P=.003) within 1.5months, after metabolic/bariatric surgery. Our study demonstrates that LRG1 level is positively associated with obesity and a lower level of plasma LRG1 predicts weight loss in metabolic/bariatric surgery. Our novel findings suggest LRG1, itself or in combination with other known factors, is a potential biomarker of inflammation and obesity.

Ascertainment of Unmet Needs and Participation in Health Maintenance and Screening of Adult Hematopoietic Cell Transplantation Survivors Followed in a Formal Survivorship Program

This study aimed to ascertain unmet needs in autologous and allogeneic hematopoietic cell transplantation (HCT) recipients actively followed in an established long-term survivorship clinic at Roswell Park Cancer Institute from 2006 to 2012. The Survivor Unmet Needs Survey (SUNS) was mailed to 209 eligible patients and returned by 110 (53% participation rate). SUNS includes 89 items covering 5 domains: Emotional Health, Access and Continuity of Care, Relationships, Financial Concerns, and Information. The top 5 specific unmet needs for autologous HCT patients were inability to set future goals/long-term plans, changes in appearance, bad memory/lacking focus, losing confidence in abilities, and paying household or other bills. For allogeneic HCT patients these 5 unmet needs were tied at 21% of respondents: ability to earn money, pay bills, feeling tired, feeling depressed, and dealing with others' expectations of “returning to normal.” The top 5 needs reported by females were all from the emotional health domain, whereas males reported financial domain unmet needs. Self-reported participation in health maintenance and screening tests varied greatly from 88% of patients having routine annual bloodwork to 13% of patients having an exercise stress test in the past year. Our findings demonstrate unmet needs in emotional health and financial burden in HCT survivors and variable compliance with survivorship screening.

"I'm healthy, I don't have pain"- health screening participation and its association with chronic pain in a low socioeconomic status Singaporean population.

BackgroundWe sought to determine the association between chronic pain and participating in routine health screening in a low socioeconomic-status (SES) rental-flat community in Singapore. In Singapore, ≥ 85% own homes; public rental flats are reserved for those with low-income.MethodsChronic pain was defined as pain ≥ 3 months. From 2009−2014, residents aged 40−60 years in five public rental-flat enclaves were surveyed for chronic pain; participation in health screening was also measured. We compared them to residents staying in adjacent owner-occupied public housing. We also conducted a qualitative study to better understand the relationship between chronic pain and health screening participation amongst residents in these low-SES enclaves.ResultsIn the rental-flat population, chronic pain was associated with higher participation in screening for diabetes (aOR = 2.11, CI = 1.36−3.27, P < 0.001), dyslipidemia (aOR = 2.06, CI = 1.25−3.39, P = 0.005), colorectal cancer (aOR = 2.28, CI = 1.18−4.40, P = 0.014), cervical cancer (aOR = 2.65, CI = 1.34−5.23, P = 0.005) and breast cancer (aOR = 3.52, CI = 1.94−6.41, P < 0.001); this association was not present in the owner-occupied population. Three main themes emerged from our qualitative analysis of the link between chronic pain and screening participation: pain as an association of “major illness”; screening as a search for answers to pain; and labelling pain as an end in itself.ConclusionsChronic pain was associated with higher cardiovascular and cancer screening participation in the low-SES population. In low-SES populations with limited access to pain management services, chronic pain issues may surface during routine health screening.

Determinants of individuals' participation in integrated chronic disease screening in Singapore

BackgroundA large pool of patients with chronic diseases remains undiagnosed globally and in Singapore. We explored factors associated with participation in a health screening exercise, using revealed preference, that is,...

Primary care characteristics and their association with health screening in a low-socioeconomic status public rental-flat population in Singapore- a mixed methods study.

BackgroundIn Singapore, subsidized primary care is provided by centralized polyclinics; since 2000, policies have allowed lower-income Singaporeans to utilize subsidies at private general-practitioner (GP) clinics. We sought to determine whether proximity to primary care, subsidised primary care, or having regular primary care associated with health screening participation in a low socioeconomic-status public rental-flat community in Singapore.MethodsFrom 2009–2014, residents in five public rental-flat enclaves (N = 936) and neighboring owner-occupied precincts (N = 1060) were assessed for participation in cardiovascular and cancer screening. We then evaluated whether proximity to primary care, subsidised primary care, or having regular primary care associated with improved adherence to health screening. We also investigated attitudes to health screening using qualitative methodology.ResultsIn the rental flat population, for cardiovascular screening, regular primary care was independently associated with regular diabetes screening (adjusted odds ratio, aOR = 1.59, CI = 1.12–2.26, p = 0.009) and hyperlipidemia screening (aOR = 1.82, CI = 1.10–3.04, p = 0.023). In the owner-occupied flats, regular primary care was independently associated with regular hypertension screening (aOR = 9.34 (1.82–47.85, p = 0.007), while subsidized primary care was associated with regular diabetes screening (aOR = 2.94, CI = 1.04–8.31, p = 0.042). For cancer screening, in the rental flat population, proximity to primary care was associated with less participation in regular colorectal cancer screening (aOR = 0.42, CI = 0.17–0.99, p = 0.049) and breast cancer screening (aOR = 0.29, CI = 0.10–0.84, p = 0.023). In the owner-occupied flat population, for gynecological cancer screening, usage of subsidized primary care and proximity to primary care was associated with higher rates of breast cancer and cervical cancer screening; however, being on regular primary care followup was associated with lower rates of mammography (aOR = 0.10, CI = 0.01–0.75, p = 0.025). On qualitative analysis, patients were discouraged from screening by distrust in the doctor-patient relationship; for cancer screening in particular, patients were discouraged by potential embarrassment.ConclusionsRegular primary care was independently associated with regular participation in cardiovascular screening in both low-SES and higher-SES communities. However, for cancer screening, in the low-SES community, proximity to primary care was associated with less participation in regular screening, while in the higher-SES community, regular primary care was associated with lower screening participation; possibly due to embarrassment regarding screening modalities.Electronic supplementary materialThe online version of this article (doi:10.1186/s12875-016-0411-5) contains supplementary material, which is available to authorized users.

우리나라 20세 이상 장애인 건강검진 수검률 추이 및 관련 요인분석

Background: People with disabilities have higher prevalence rates and earlier onset of chronic disease than the non-disabled; therefore, their participation in health screening is important. This study evaluates the participation rate and trends in health screening of people with disabilities, and examines the association between their participation rate and disability characteristics, and socioeconomic status. Methods: Data on disability-related characteristics were collected from the National Disability Registry, and participants' corresponding health examination data were taken from the Korean National Health Insurance Corporation between 2002 and 2011. A total of 873,819 participants aged <TEX>${\geq}20$</TEX> years were analyzed in this study. Results: The rate of participation of people with disabilities in health screening has increased each year, but their participation rate is lower than that of the total population. The participation rate was lower in females than in males; the elderly group than in the younger group; those who live in city areas than rural areas; self-employed for health insurance than employees; those with an internal organ disability than those with an external physical disability; those with a severe disability than those with a mild disability; and those with a short-term disability than for those with a long-term disability. Conclusion: The factors associated with participation rate are age, sex, socioeconomic status, and disability characteristics. These findings indicate that health check-ups of people with disabilities should be promoted using an approach that takes into account the large individual differences in socioeconomic status and disability characteristics in this population.

Variability between self-reported diabetes and measured glucose among health screening participants in South Central Kentucky

AimsTo assess self-reported diabetes and random glucose among health screening participants and examine factors associated with these two diabetes outcomes. MethodsStudy subjects were adults aged ≥18 years who participated in diabetes screenings via a mobile health clinic operated by the Institute for Rural Health at Western Kentucky University from 2006 to 2011. Data on self-reported diabetes were based on physicians’ past diagnosis. Random plasma glucose was obtained during the screenings. Non-fasting plasma glucose levels of ≥180mg/dl and ≥140mg/dl were used as cutoffs to determine diabetes and diabetes or pre-diabetes, respectively. Logistic regression was used to examine factors associated with self-reported diabetes and elevated non-fasting glucose levels controlling for comorbidities and sociodemographic factors. ResultsThe proportion of self-reported diabetes was 9.6%. The proportion of participants with ≥180mg/dl was 3.2% and that with ≥140mg/dl was 7.4%. Odds ratios indicated that self-reported diabetes was higher in older and obese groups and those who had hypertension and hypercholesterolemia and family history of diabetes, while elevated non-fasting glucose levels were higher among participants without health insurance and those who reported they had diabetes. ConclusionsVariability in risks between self-reported diabetes and measured glucose should be incorporated in diabetes self-care.

Respiratory symptoms and lung function 8–10 months after community exposure to chlorine gas: a public health intervention and cross-sectional analysis

BackgroundWe implemented a community based interventional health screening for individuals located within one mile of a 54 metric tons release of liquid chlorine following a 16 tanker car train derailment on 6 January, 2005 in Graniteville, South Carolina, USA. Public health intervention occurred 8–10 months after the event, and provided pulmonary function and mental health assessment by primary care providers. Its purpose was to evaluate those exposed to chlorine for evidence of ongoing impairment for medical referral and treatment. We report comparative analysis between self-report of respiratory symptoms via questionnaire and quantitative spirometry results.MethodsHealth assessments were obtained through respiratory symptom and exposure questionnaires, simple spirometry, and physical exam. Simple spirometry was used as the standard to identify continued breathing problems. Sensitivity, specificity, positive and negative predictive values were applied to evaluate the validity of the respiratory questionnaire. We also identified the direction of discrepancy between self-reported respiratory symptoms and spirometry measures. Generalized estimation equations determined prevalence ratios for abnormal spirometry based on the presence of participant persistent respiratory symptoms. Covariate adjustment was made for participant age, sex, race, smoking and educational status.ResultsTwo hundred fifty-nine people participated in the Graniteville health screening; 53 children (mean age = 11 years, range: <1-16), and 206 adults (mean age = 50 years, range: 18–89). Of these, 220 (85%) performed spirometry maneuvers of acceptable quality. Almost 67% (n = 147) displayed abnormal spirometry, while 50% (n = 110) reported persistent new-onset respiratory symptoms. Moreover, abnormal spirometry was seen in 65 participants (29%) who did not report any discernible breathing problems. This represented a net 16.8% underreporting of symptoms. Sensitivity and specificity of questionnaire self-report of symptoms were low at 55.8% and 61.6%, respectively. Persistent cough (41%) and shortness of breath (39%) were the most frequently reported respiratory symptoms.ConclusionEight to ten months after acute chlorine exposure, the Graniteville health screening participants under-reported respiratory symptoms when compared to abnormal spirometry results. Sensitivity and specificity were low, and we determined that relying upon the self-report questionnaire was not adequate to objectively assess the lung health of our population following irritant gas exposure.

The Role of Personality in Predicting Repeat Participation in Periodic Health Screening

Drawing on the Five-Factor Model of personality, the aim of the present study was to find out which personality traits predict health maintenance behaviors, reflected in routine participation in health screenings, over and above objective and subjective health status. Participants were 2,803 employed individuals (61% men), free of background diseases, who underwent a routine health examination and were subsequently notified whether they were healthy or at risk. These participants were invited to repeat the examination within the next few years, as is medically recommended. Logistic and negative binomial regressions were used to predict participants' odds of returning for a second examination, within the next 7 years, as well as the number of consecutive visits, while controlling for sociodemographic factors, objective and subjective health, and length of follow-up. We found that both endpoints were positively predicted by Conscientiousness and negatively predicted by Extraversion and Openness. The association between Neuroticism and these endpoints followed a bell-shaped curve (i.e., individuals high or low in Neuroticism were less likely to return). The present findings suggest that personality traits should be taken into consideration in the planning and implementation of health-promoting interventions.

Predictors of risk-based medical follow-up: a report from the childhood cancer survivor study

The purpose of this study is to conduct an intervention study designed to assess the effectiveness of using a newsletter to increase medical follow-up in pediatric cancer survivors at risk of selected treatment complications. Survivors participating in the Childhood Cancer Survivor Study who were at least 25years of age and at risk of cardiovascular disease, breast cancer, or osteoporosis related to previous cancer treatment were randomly assigned to receive a newsletter featuring brief health risk information or a newsletter including an insert providing more comprehensive health risk information. A follow-up survey distributed 24months after the newsletter intervention assessed predictors of medical follow-up. Overall, there were no differences found among the groups in terms of access to a treatment summary, medical follow-up, discussion of childhood cancer health risks, and medical screening for the targeted health behaviors. One exception, indicating borderline significance was that women at risk for osteoporosis who received the newsletter insert were more likely to have discussed their risk with a doctor than those who only received the brief information (10.1% vs. 4.0% p = 0.05). Discussion of breast cancer (OR = 2.15; 95% CI = 1.74-2.66), heart disease (OR = 5.54; 95% CI = 4.67-6.57) and osteoporosis (OR = 10.6; 95% CI = 8.34-13.47) risk with physician significantly predicted report of undergoing screening for targeted behavior in previous 2years as did physician access to treatment summary. More detailed content in a newsletter had minimal effect on recommended screening. However, survivor's discussion of cancer-related risks with one's doctor significantly influenced participation in health screening. These results highlight the integral role of communication in health behavior. This study is designed to assess communication strategies that increase medical follow-up in pediatric cancer survivors at risk of selected treatment complications. The results are of great importance not only to the pediatric oncology community but also the broad range of adult oncology medical specialties who are directly involved in the long-term medical care of this ever increasing population of cancer survivors.

A sonographic doppler study of hepatic vein, portal vein and hepatic artery in liver cirrhosis: correlation of hepatic haemodynamics and liver dysfunction

s / Clinical Radiology 67 (2012) S1–S10 S10 Results: We present a comprehensive pictorial review of the features of PAPVD across several imaging modalities, including tips for the general radiologist. We also describe the congenital associations which, if present, should prompt a search for PAPVD. Knowledge of the above is important particularly in the diagnostically challenging patient or where precise anatomicalmappingof thepulmonaryveins is requiredprior to intervention. Conclusion: The radiologist plays an important role in diagnosing PAPVD. A knowledge of the imaging features will lead to prompt diagnosis and facilitate pre-procedural planning, contributing to a favourable patient outcome. The CT features of chronic thromboembolic pulmonary hypertension (CTEPH) Authors: Shalini Wijesuriya, Ladli Chandratreya Purpose: Chronic occlusion of pulmonary arteries by emboli can lead to a progressive elevation of pulmonary artery pressures with sequelae such as chronic thromboembolic pulmonary artery hypertension (CTEPH) and right ventricular dysfunction. Diagnosis and early recognition of CTEPH is crucial as it is potentially curablewith pulmonary thromboendarterectomy and if left untreated, is associatedwith significant morbidity andmortality. Unfortunately, patients may go undetected for years and diagnosis is made challenging by the non-specific nature of the clinical presentation. CTEPH is being increasingly recognised and as the radiologist may be the first individual to make a diagnosis of CTEPH, knowledge of the conventional and less common CT features is crucial. Methods and materials: A pictorial review of cases of chronic thromboembolic pulmonary hypertension based on experiences at our institution. Results: We present a comprehensive pictorial review of the vascular, cardiac and pulmonary parenchymal CT features of chronic thromboembolic pulmonary hypertension. Furthermore, we discuss potential pitfalls and help distinguish CTEPH from other common mimics such as acute embolism and idiopathic pulmonary hypertension. Conclusion: We hope that highlighting the key diagnostic features in CTEPH will improve confidence, notably amongst trainees, leading to fewer diagnostic delays and an improvement in overall patient outcome. A sonographic doppler study of hepatic vein, portal vein and hepatic artery in liver cirrhosis: correlation of hepatic haemodynamics and liver dysfunction Authors: Richard H. Lo, Azizah Mohamed Afif, Yanyan Wang, Denise Lau, Chin C. Ooi Purpose: To evaluate parameters involved in haemodynamics of liver vasculature in patients with cirrhosis and in normal healthy volunteers using Doppler Ultrasound. Methods and Materials: A study sample of 32 patients with Child-Pugh A (n1⁄425), B (n1⁄45), and C (n1⁄42) liver cirrhosis was compared with a control group of 26 normal health screening participants. Right hepatic vein (RHV), right portal vein (RPV) and main hepatic artery were interrogated. Results: All patients in control group showed normal triphasic waveform in RHV. In the study group, RHV blunted waveform was detected in 3 patients in Child-Pugh A, 1 in B and all patients in C category. Waveform alteration was independent of Child-Pugh score. Hepatic Artery Resistive Index (HARI) was significantly higher in study group than in control group (p<0.001). Maximum Portal Vein Velocity (MPVV) also was significantly lower in study group than in control group (p1⁄40.02). Mean Maximum Hepatic Vein Velocity (MHVV) and Maximum Hepatic Artery Velocity (MHAV) did not show significant difference between the 2 groups, with p1⁄40.16 and p1⁄40.38 respectively. Conclusion: Altered waveform of hepatic veins is suggestive of changes within a cirrhotic liver. HARI and MPVV can be useful parameters to assess liver cirrhosis. Doppler Ultrasound is a good non-invasive assessment tool for evaluating the haemodynamics of liver cirrhosis.

Screening for cardiovascular disease risk factors in an urban low-income setting at baseline and post intervention: a prospective intervention study

Not all segments of society might have equal access to screening. We determined predictors for regular cardiovascular health screening at baseline amongst those of low socioeconomic status (SES) and evaluated the effectiveness of a 6-month intervention on screening in this group compared to a high-SES group. The study population involved all residents aged ≥ 40 years in two housing estates comprising owner-occupied housing (high SES) and rental flats (low SES) in Singapore. From 2009 to 2011, residents not being screened regularly at baseline for hypertension, diabetes, and dyslipidaemia were offered free and convenient blood pressure, fasting blood glucose, and lipid testing over 6 months. Chi-squared and multi-level logistic regression identified predictors of regular screening at baseline; likelihood ratio and Cox regression analysis identified predictors of screening participation post intervention. Participation was 78.2% (1081/1383). At baseline, in the low-SES group, 41.7% (150/360), 38.8% (177/456), and 30.8% (128/416) had gone for regular hypertension, diabetes, and dyslipidaemia screening, respectively; compared with higher numbers in the high-SES group. Sociodemographic factors predicting regular screening in the low-SES community included being married and not smoking. Post intervention, screening rates rose significantly (p < 0.001) by similar proportions in both communities. Staying in a lower-SES community (adjusted relative risk (aRR) 0.61, 95% CI 0.37-0.99, p = 0.048) and having hypertension (aRR 0.45, 95% CI 0.18-0.98, p = 0.049) was associated with lower take-up; Chinese ethnicity (aRR 1.84, 95% CI 1.00-3.43, p = 0.050) and employment associated with higher take-up (aRR 1.57, 95% CI 1.03-2.60, p = 0.040). Participation in cardiovascular health screening was poor amongst those of low SES; a 6-month intervention programme improved participation in this population.

The effect of neighborhood, socioeconomic status and a community-based program on multi-disease health screening in an Asian population: A controlled intervention study

Objectives We studied whether individual socioeconomic and neighborhood factors such as living in a poor community independently affected health screening participation. Methods We studied 3 blocks of public-rental flats (the poorer neighborhood) adjacent to 3 blocks of owner-occupied public housing (the better-off neighborhood) in a precinct in Taman Jurong, Singapore. Demographic details and reasons for not having regular hypertension, diabetes mellitus, hyperlipidemia and colorectal cancer screening were collected from 2009 to 2010. An access-enhancing intervention was implemented in both neighborhoods to raise health screening rates. Results Participation rates for rental flats and owner-occupied flats were 89.0% (356/400) and 70.2% (351/500) respectively. Living in a better-off neighborhood was independently associated with diabetes mellitus (66% vs. 35%, adjusted odds ratio (AOR) = 2.12, p < 0.01), hyperlipidemia (53% vs. 26%, AOR = 4.34, p < 0.01) and colorectal cancer screening (17% vs. 6%, AOR = 15.43, p < 0.01), as were individual socioeconomic factors such as employment, need for financial aid and household income. Uptake of all screening modalities significantly increased in the poorer neighborhood post-intervention (all p < 0.05). Cost was cited more commonly as a barrier to health screening in the poorer neighborhood. Conclusion Differing neighborhoods within one geographical location, as well as individual socioeconomic factors, were independently associated with differences in health screening.

Multi-disease Health Screening in an Urban Low-income Setting: A Community-based Study

We were interested to determine the participation rates for health screening in a multi-ethnic urban low-income community. We assessed the health screening rates at baseline, collected data on reasons for non-participation and assessed the impact that a 5-month intervention had on health screening in this community. The study population involved all residents aged ≥40 years, living in heavily subsidised public rental flats in Taman Jurong Constituency, Singapore. From January 2009 to May 2009, we collected baseline information and offered eligible residents free blood pressure, fasting blood glucose and lipid measurements, fecal occult blood testing and Pap smears. Screenings were conducted either at or near the residents' homes. The participation rate was 60.9% (213/350). At baseline, 18.9% (24/127), 26.4% (42/159) and 18.7% (31/166) had gone for regular hypertension, diabetes and hyperlipidaemia screening, respectively; 3.8% (6/157) and 2.9% (2/70) had had regular colorectal and cervical cancer screening, respectively. Post-intervention, rates for hypertension screening increased to 97.6% but increases for other modalities were marginal. High cost, lack of time, not at risk, too old, or unnecessary for healthy people were commonly-cited reasons for skipping regular health screening. Being unemployed was associated with missing regular hypertension screening (adjusted OR = 2.48, CI = 1.12-5.53, P = 0.026); those who did not need financial aid were less likely to miss regular hyperlipidaemia screening (adjusted OR = 0.27, CI = 0.10-0.72, P = 0.008). The participation rates for health screening were poor in this low-income community. More can be done to encourage regular health screening participation amongst this segment of the populace, both by reducing costs as well as addressing misperceptions.
