INTRODUCTIONThis study assessed the health screening behaviour of Singaporeans and evaluated factors associated with low uptake of screening tests.

MATERIALS AND METHODSData from the 2010 National Health Survey, which was conducted on Singapore citizens and permanent residents, was used in this analysis. Multivariate Cox regression was used to evaluate the relationship between sociodemographics and health screening behaviour for selected chronic diseases (hypertension, diabetes and hypercholesterolaemia) and cancers (cervical, breast and colorectal). National recommendations for age at which screening should be initiated and appropriate screening interval were used to define appropriate screening behaviour.

RESULTSMore respondents have had their last chronic disease screening done within the recommended time period compared to cancer screening. A total of 77.8%, 63.4% and 54.9% of the respondents had their last hypertension, diabetes and hypercholesterolaemia done within the recommended time period respectively, while less than 50% of the respondents had their cervical (45.8%), breast (32.9%) and colorectal (20.2%) cancer screenings done within the recommended time period. Respondents with higher household income or more years of education were more likely to have undergone screening within the recommended time period. Indians, who are at higher risk of chronic diseases such as diabetes and hypercholesterolaemia, were also more likely to have been screened. A total of 69.9% and 79.5% of the respondents with previously undiagnosed diabetes and hypertension had reported to have done diabetes and hypertension screenings respectively, within the recommended time period.

CONCLUSIONSociodemographic factors that could be associated with a lower uptake of screening tests include: 1) low household income, 2) low education level, and 3) Malay ethnicity. Health promotion programmes and outreach to these groups can be enhanced to further improve screening uptake.

OBJECTIVES: Both organized and opportunistic screening programs have been widely used in Korea. This paper examined the determinants of the use of opportunistic screening programs in Korea. METHODS: The subjects were a national stratified random sample of 10,254 people aged 45 or older from the first wave of the Korean Longitudinal Study of Ageing in 2006. A logit model was used to examine the determinants of the use of opportunistic screening programs in terms of the demographic and socioeconomic characteristics, the type of health insurance and the health status. RESULTS: Thirteen point seven percent of the individuals received opportunistic screening programs within 2 years from the time the survey was conducted in 2006. The individuals who graduated from college or who had even more education were 3.0 times more likely to use opportunistic screening programs compared with the individuals who were illiterate. The individuals who resided in urban areas and who had religious beliefs were more likely to receive opportunistic screening programs compared with their counterparts. Those who were in the first quartile for the total household assets were 2.6 times more likely to use opportunistic screening programs than those who were in the fourth quartile for the total household assets. Privately insured people were 1.6 times more likely to use opportunistic screening programs than those who were not insured. Finally, the individuals who self-assessed their health status as worst were 2.1 times more likely to use opportunistic screening programs compared individuals who self-assessed their health status as best. CONCLUSIONS: This study suggests that opportunistic screening programs can be an indicator for whether or not an individual is among the advantaged group in terms of their socioeconomic characteristics and type of health insurance.

INTRODUCTIONWe 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.

MATERIALS AND METHODSThe 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.

RESULTSThe 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).

CONCLUSIONThe 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.

INTRODUCTIONTo study the understanding and perceived vulnerability of diabetes mellitus among Singapore residents, and determine the predictors associated with screening for diabetes mellitus among the people without the condition.

MATERIALS AND METHODSA population-based survey was conducted from December 2004 to October 2005 involving Singapore residents aged 15 to 69 years. Using a standard questionnaire, Health Survey Officers interviewed household members on their understanding and perceived vulnerability of diabetes mellitus and associated cardiovascular risk factors. Data were analysed using SPSS v13.

RESULTSThe response rate was 84.5%. Of 2,632 respondents, 291 (11.1%) have diabetes mellitus. Compared to respondents without diabetes, respondents with the disease had better understanding of diabetes and they had favourable health practice of screening for cardiovascular risk factors. Having diabetes mellitus was not associated with a healthier lifestyle. Among non-diabetics, those who had a family history of diabetes had better knowledge and health practices than those who had not. They were significantly more likely to recognise the symptoms and signs (61.5% vs 54.5%) and the causes of diabetes (70% vs 58.2%); and were more likely to have ever tested for diabetes (76.1% vs 60.4%), with P <0.001. Socio-demographic characteristics, family history, understanding and perception on the vulnerability of diabetes were identified as predictors associated with health screening for the disease.

CONCLUSIONAmong all respondents, better understanding was found to be associated with favourable health-preventive behaviours. However, it did not translate into healthier lifestyle. Cultural and socio-demographic profiles must be factored in for any effort on lifestyle modifications.

INTRODUCTIONMany alcohol-related problems often go undetected and untreated. In Singapore, no epidemiological studies have been done in general hospitals on alcohol use disorders (AUD), i.e. alcohol dependence and abuse (DSM-IV-TR). Such findings are useful in planning AUD liaison services. In this study, we aim to estimate the prevalence of AUD among non-psychiatric inpatients and to determine the rates of identification and intervention rendered by medical staff.

MATERIALS AND METHODSNon-psychiatric medical and surgical wards inpatients aged 21 years and above were recruited over a 3-month period. The Alcohol Use Disorders Identification Test (AUDIT) was used to screen for AUD and the MINI International Neuropsychiatric Interview (MINI English Version 5.0.0) was administered to diagnose AUD if the AUDIT score was 8 or above. Case notes were independently reviewed for AUD identification and if interventions were offered during admissions.

RESULTSA total of 5599 inpatients were screened, of which 673 (12%) completed the screening using the AUDIT, and of these, 154 (2.8% of total sample) were positive for AUDIT. In this group, 107 were diagnosed with AUD. The estimated prevalence was 1.9% (approximately 400 cases per year per hospital). The medical staff identified only 25 (23.4%) cases of AUD, out of which, majority of them (76%) were rendered interventions.

CONCLUSIONThe rate of AUD identification by medical staff was low. Of those identified, majority were given interventions. Thus, the training of health care staff to identify AUD together with the implementation of brief interventions should be considered.

OBJECTIVES: While cervical cancer is one of the leading cancers among women worldwide, there are a number of effective early detection tests available. However, the participation rates in cervical cancer screening among Korean women remain low. After the nationwide efforts in 1988 and thereafter to encourage participation in cervical cancer screening, few studies have investigated the effects of socioeconomic inequality on participation in cervical cancer screening. The purpose of this study was to investigate 1) the level of socioeconomic disparities in receiving cervical cancer screening by age group and 2) if there was an improvement in reducing these disparities between 1995 and 2001. METHODS: Using data from the Korean National Health Status, Health Behavior and Belief Survey in 1995, and the Korean National Health and Nutrition Examination Surveys from 1998 and 2001 (sample sizes of 2,297, 3,738, and 3,283), age-standardized participation rates were calculated according to education level, equivalized household income, and job status. Odds ratios and the relative inequality index (RII) were also calculated after controlling for age. RESULTS: Women with lower education levels were less likely to attend the screening test, and the disparities by education level were most pronounced among women aged 60 years and older. The RIIs among women 60 years and older were 3.64, 4.46, and 8.64 in 1995, 1998, and 2001, respectively. Higher rates of participation were reported among those in the highest income category, which was more notable among the middle aged women (40s and 50s). An inconsistent trend in the rate of participation in cervical cancer screening by occupational level was found. CONCLUSIONS: Indicators of socioeconomic position seem to have varying impacts on the inequalities in the rates of participation in cervical cancer screening according to age group. These results demonstrate the need for more aggressive and age-based interventions and policy programs to eliminate the remaining inequalities.

OBJECTIVES: This study describes trends in the socioeconomic disparities in breast cancer screening among US women aged 40 or over, from 2000 to 2005. We assessed 1) the disparities in each socioeconomic dimension; 2) the changes in screening mammography rates over time according to income, education, and race; and 3) the sizes and trends of the disparities over time. METHODS: Using data from the Behavioral Risk Factor Surveillance System (BRFSS) from 2000 to 2005, we calculated the age-adjusted screening rate according to relative household income, education level, health insurance, and race. Odds ratios and the relative inequality index (RII) were also calculated, controlling for age. RESULTS: Women in their 40s and those with lower relative incomes were less likely to undergo screening mammography. The disparity based on relative income was greater than that based on education or race (the RII among low-income women across the survey years was 3.00 to 3.48). The overall participation rate and absolute differences among socioeconomic groups changed little or decreased slightly across the survey years. However, the degree of each socioeconomic disparity and the relative inequality among socioeconomic positions remained quite consistent. CONCLUSIONS: These findings suggest that the trend of the disparity in breast cancer screening varied by socioeconomic dimension. ontinued differences in breast cancer screening rates related to income level should be considered in future efforts to decrease the disparities in breast cancer among socioeconomic groups. More focused interventions, as well as the monitoring of trends in cancer screening participation by income and education, are needed in different social settings.

Participation in a screening program by itself may not improve clinical outcomes. Treatment gaps in the program may limit its full benefit. We evaluated statin prescription rates for subjects with sustained hypercholesterolemia to assess the treatment gaps in the National Health Screening Program (NHSP) in Korea. A retrospective, random cohort was established among National Health Insurance Corporation (NHIC) members. Finally, we examined 465,499 individuals who attended the NHSP from 2003 to 2010 without any history of dyslipidemia, statin prescription, or hospitalization for cardiovascular events until the end of 2002. The subsequent statin prescription rates were identified from the NHIC medical service claim database from 2003 to 2011. Descriptive data and odds ratio from multivariate logistic analyses on statin prescription rates and the corresponding correlations were evaluated. The NHSP detected 114,085 (24.5%) cases of newly diagnosed hypercholesterolemia. However, only 8.6% of these received statin prescription within 6 months of diagnosis. For cases of sustained hypercholesterolemia determined in the next screening visit by the NHSP, the statin prescription rate increased, but only to 12.2%. Statin prescriptions were more common among females, older individuals, and hypertension or diabetes patients. Furthermore, the statin prescription rates had increased over the study period. The NHSP exhibited low statin prescription rate which has been improving. For the NHSP to be effective, it would be worthwhile to decrease the gap between the diagnosis of hypercholesterolemia and the following treatment.
