Hidden diabetes in the UK: use of capture-recapture methods to estimate total prevalence of diabetes mellitus in an urban population

Prevalence of diabetes and pre-diabetes in Greece. Results of the First National Survey of Morbidity and Risk Factors (EMENO) study

AIMS

To report the results of the first national Health Examination Survey (HES) on the prevalence of diabetes, its pharmacologic treatment and level of control, as well as pre-diabetes in Greece.

METHODS

Data were derived from the National Survey of Morbidity and Risk Factors (EMENO), in a randomly selected, representative sample of the adult Greek population. Sampling weights were applied to adjust for study design and post-stratification weights to match sample age/sex distribution to the population. Non-response was adjusted by inverse probability weighting. Weighted prevalence estimates are provided.

RESULTS

A total of 4393 persons with HbA1c and/or fasting plasma glucose measurements were included. Total diabetes prevalence was 11.9% (95% CI: 10.9-12.9), known diabetes 10.4% (9.5-11.4), and unknown 1.5% (1.1-1.9), with considerable increase in older age groups and no difference between genders. Pre-diabetes prevalence was 12.4% (11.4-13.6). The majority of persons with known diabetes were receiving metformin. Of those with known diabetes (and measured HbA1c), 70.9% were well controlled (HbA1c <7.0%).

CONCLUSIONS

This first representative national HES showed high prevalence of diabetes in Greece, with low prevalence of unknown diabetes. Pre-diabetes prevalence is also substantial. These results will hopefully enable national authorities develop tailored and efficient strategies for disease prevention and management.

Prevalence of hypertension and diabetes morbidity among adults in a few urban slums of Bangalore city, determinants of its risk factors and opportunities for control - A cross-sectional study

Introduction:

In World Health Organization's(WHO) South-East Asia region(SEAR), India accounts for >2/3rd of total deaths due to non-communicable diseases(NCD). Annually, NCDs account for ~60% of all deaths in India. Apart from the known risk factors, an individual's physical environment, behavioral and biological susceptibility are known to associated with NCDs. Social factors tend to create barriers for accessing healthcare among the poor people.

Objectives:

i)To screen and diagnose hypertension and diabetes among individuals aged >30 years, and its associated risk factors such as obesity and tobacco consumption. ii) To deliberate on the social determinants influencing this survey, and suggest suitable recommendations for the National Programme for prevention and control of Cancer, Diabetes, Cardiovascular disease and Stroke (NPCDCS).

Methods:

As a component of NPCDCS, the present survey was conducted in a few urban slums of Bangalore city during 2010. The collaborators for the conduct of this survey include the Ministry of health and family welfare, Director of health and family welfare services and Medical colleges in Bangalore city.

Results:

In our study, we found a prevalence proportion of 21.5% for hypertension, 13.8% for diabetes and 30.4% were co-morbid with both the diseases. Consumption of tobacco(any form) was present in 5.1% of the study subjects, overweight among 32.4% and obesity among 20.0%. The study population comprises 18.96% of the source, and the main reason for inadequate utilization was lack of Programmatic awareness.

Conclusion:

NPCDCS program needs to conceptualize the relevant social factors which determine access to screening and diagnostic healthcare services, including behavior change initiatives. For Program effectiveness, changes at the level of healthcare system need to adopted.

Prevalence of diabetes in Australia: insights from the Fremantle Diabetes Study Phase II

BACKGROUND

Accurate diabetes prevalence estimates are important for health service planning and prioritisation. Available data have limitations, suggesting that the contemporary burden of diabetes in Australia is best assessed from multiple sources.

AIMS

To use systematic active detection of diabetes cases in a postcode-defined urban area through the Fremantle Diabetes Study Phase II (FDS2) to complement other epidemiological and survey data in estimating the national prevalence of diabetes and its types.

METHODS

People with known diabetes in a population of 157 000 were identified (n = 4639) from a variety of sources and those providing informed consent (n = 1668 or 36%) were recruited to the FDS2 between 2008 and 2011. All FDS2 participants were assigned a type of diabetes based on clinical and laboratory (including serological and genetic) features. Data from people identified through the FDS2 were used to complement Australian Health Survey and National Diabetes Services Scheme prevalence estimates (the proportions of people well controlled on no pharmacotherapy and registering with the National Diabetes Services Scheme respectively) in combination with Australian Bureau of Statistics data to generate the prevalence of diabetes in Australia.

RESULTS

Based on data from multiple sources, 4.8% or 1.1 million Australians had diabetes in 2011-2012, of whom 85.8% had type 2 diabetes, 7.9% type 1 diabetes and 6.3% other types (latent autoimmune diabetes of adults, monogenic diabetes and secondary diabetes).

CONCLUSIONS

Approximately 1 in 20 Australians has diabetes. Although most have type 2 diabetes, one in seven has other types that may require more specialised diagnosis and/or management.

Estimated costs of acute hospital care for people with diabetes in the United Kingdom: a routine record linkage study in a large region

AIMS

Diabetes represents a notable burden to health payers. The purpose of this study was to estimate acute hospital care costs of treating people with diabetes with reference to the costs of treating those without.

METHODS

This was a retrospective study. Data from routine hospital practice were available from a large health region (439 000 people), with an estimated prevalence of diabetes of 3.4%. Common records were identified using probabilistic record linkage. Cost estimates were attributed to admissions using healthcare resource group software. Outpatient costs were attributed using published values. Data described are for 2004, and prices in pounds sterling for 2005. Standardised cost ratios were estimated to compare the costs observed in the diabetes population with those expected from the non-diabetic reference population.

RESULTS

The total annual cost of admissions was pound28 944 811 per 100 000 people, of which pound3 650 869 per 100 000 (12.6%) was diabetes related. The standardised cost rate of inpatient treatment was 2.9. The total cost of outpatient attendances was pound6 589 971 per 100 000, of which pound711 431 per 100 000 (10.8%) was diabetes related. The standardised cost ratio for outpatient care was 4.1. The total cost of hospital care for patients with diabetes was pound11 206 986 per 100 000, or 12.3% of acute hospital expenditure. The combined standardised cost ratio was 3.1. Costs of care for inpatient treatment increased from 8.7% of revenue in 1994 to 12.3% in 2004.

CONCLUSIONS

The costs of acute hospital care for treating people with diabetes increased markedly over a decade, and now exceed 12% of revenue.

The changing prevalence of diagnosed diabetes and its associated vascular complications in a large region of the UK

AIMS

To characterize the prevalence of diabetes in a large health district in 2004 and compare it with a previous estimate made in 1996.

METHODS

The study population comprised the resident population of Cardiff and the Vale of Glamorgan. Routine record linkage was used to identify patients from various sources of hospital and mortality data. Patients with diabetes were identified according to biochemistry test results, coding on routine data or attendance at a diabetes-related clinic. Diabetes-related complications were ascribed according to coding on routine data.

RESULTS

It was possible to identify 17 088 people with diabetes alive on 1 January 2005. Of these patients, 9064 (53.0%) were male and 8024 (47.0%) were female. Mean age (+/- sd) was 59.6 +/- 18.9 years for males and 61.2 +/- 20.4 years for females. The crude prevalence of diabetes in 2005 was 3.9% (3.4% adjusted) compared with 2.5% in 1996 (2.3% adjusted). With the exception of females aged > or = 75 years, the prevalence of diabetes increased in all age- and sex-specific subgroups. Within the 2005 cohort, over two-thirds has no recorded complications compared with approximately one half of the 1996 cohort. The prevalence of individual complications decreased, with the exception of renal complications.

CONCLUSIONS

The prevalence of identified diabetes appears to have increased substantially over a relatively short period of 9 years to 2004. The increase in prevalence was 46%, with an increase in numbers of patients with diabetes of 53%. A number of factors are likely to have contributed to this, including an increase in case ascertainment.

Sexual problems and help-seeking behaviour in adults in the United Kingdom and continental Europe

OBJECTIVES

To study sexual activity, the prevalence of sexual dysfunction, and related help-seeking behaviour patterns among middle-aged and older people in the UK and Europe.

SUBJECTS AND METHODS

A telephone survey was conducted using a structured questionnaire covering demographics, health, relationships, and sexual behaviour, attitudes and beliefs. In the UK, 1500 individuals completed the survey.

RESULTS

Overall, 69% of men and 56% of women reported having sexual intercourse during the past year. The most common male sexual problems, i.e. early ejaculation (20%) and erectile dysfunction (18%), were more common in the UK than in other European regions. The most common female sexual problems, i.e. a lack of sexual interest (34%) and a lack of pleasure in sex (25%), were also more common in the UK than in other European regions. Only 26% of men and 17% of women had discussed their sexual problem(s) with a doctor.

CONCLUSION

Many people in the UK maintain sexual interest and activity into middle age and beyond. Although they experience sexual problems, few seek medical help. This might be because they do not perceive such problems as serious or sufficiently upsetting, and/or are not aware of available treatments.
