OBJECTIVE: To investigate the prevalence and incidence of non-insulin dependent diabetes (NIDDM) in China by WHO criteria. METHODS: In the prevalence survey of NIDDM all 110660 participants (55391 men, 53269 women) were inhabitants of Daqing City, the largest oil center in northeast China, accounting for 87.3% of the 25 to 74 aged population in this city. They were screened by measuring two-hour plasma glucose concentrations (PG2 h) after a breakfast containing at least 80 g of carbohydrate, then a standard oral glucose tolerance test (OGTT, 75 g glucose load) was performed in 4209 subjects with PG2 h more than 6.67 mmol/L in this screen. NIDDM and impaired glucose tolerance (IGT) were diagnosed using WHO criteria. Incidence survey was made in 36471 non-diabetics identified in the prevalence survey. Two-hour urine-glucose after breakfast was determined during first screen. The urine-glucose trace or positive subjects were then followed by OGTT. Glucose was measured by glucose oxidation method. RESULTS AND CONCLUSIONS: In prevalence survey, 630 newly diagnosed NIDDM (296 males, 334 females) and 596 IGT (318 males, 278 females) were found in 110660 (male:female = 55391/53269) studied subjects in addition to 190 previously diagnosed NIDDM. Thus the total prevalence of NIDDM was 7.7/1000, and IGT was 5.5/1000. Standardized to the Chinese population in 1982, the prevalences are 12.6/1000 (95% CI = 12.0/1000-13.3/1000) and 7.7/1000 (95% CI = 7.16/1000-8.19/1000) respectively. In the incidence survey, 191 NIDDM (103 males, 88 females) were diagnosed in the 36471 (male:female = 18801/17670) non-diabetics from 1986 to 1990, thus the annual incidence of NIDDM was 131/100000 (137 males, 125 females). Standardized incidence is 131/100000 (95% CI = 94/100000-168/ 100000). It is estimated that there would be more than 700 thousand new diabetics per year in 24-74 years old Chinese if Chinese population were 1.3 billion in the early 21st century. 相似文献

The aim of this study was to determine, first, whether racial differences exist in the seroprevalence of Helicobacter pylori infection in Singapore, and second, whether these differences correlate with racial differences in peptic ulcer frequency. A commercial serological test for immunoglobulin (Ig)G antibody to H. pylori which was 90% sensitive and 83% specific in our population was used to screen 403 adult blood donors of Chinese, Malay and Indian origin, aged between 15-60 years. Serum specimens from 84 paediatric patients admitted to the Paediatrics Department, National University of Singapore, with non-gastroenterological illnesses were also tested. In all three races, seroprevalence of H. pylori increased with age. Indians have the highest prevalence of infection followed by Chinese and Malays. Peptic ulcer prevalences are known to be highest in Chinese, followed by Indians and Malays. The Malays have the lowest prevalence of H. pylori and peptic ulcer among the three races in Singapore. Indians have a higher prevalence of H. pylori antibodies but a lower frequency of peptic ulcer than the Chinese. Racial differences in peptic ulcer frequency between Chinese and Indians are not explained by the prevalence of H. pylori infection; other environmental or genetic factors may be involved. 相似文献

Prevalence of glucose intolerance and other noncommunicable diseases has been examined in subjects aged 35 years and over in semirural and urban communities in the Fergana Valley in the eastern part of Uzbekistan, Central Asia. Diabetes and impaired glucose tolerance (IGT) were diagnosed according to the recommendations of the latest WHO Study Group on diabetes. Crude prevalence of diabetes was 9% and 5%, respectively, in semirural men and women, 13% and 9% in urban men and women. Crude prevalence of impaired glucose tolerance (IGT) was 6% and 9%, respectively, in semirural men and women, 9% and 8% in urban men and women. After adjustment for non-response, prevalence of diabetes was 5% and 4%, respectively, in semirural men and women and 8% in both urban men and women. Adjusted prevalence of IGT was 4% and 8%, respectively, in semirural men and women, 5% and 6% in urban men and women. The majority of subjects with a prior diagnosis of diabetes were being treated with oral hypoglycaemic agents. Almost one-half of subjects in both communities had body mass index of 25 kg m(-2) or greater. Central obesity (waist-hip ratio 0.95 or greater for men, 0.85 or greater for women) was observed in over one-quarter of subjects in both communities. Clinical hypertension was not frequent by international standards (9% in semirural subjects and 13% in urban subjects) but a number of subjects who were clinically normotensive claimed to be taking antihypertensive medication. It is concluded that glucose intolerance and central obesity are common in this region of Uzbekistan, about which there was previously little information. 相似文献

OBJECTIVES: To determine age-specific prevalence of hypertension and blood pressure (BP) levels in relation to diet and lifestyle factors in North Indians. DESIGN AND SETTING: Cross-sectional survey in 20 randomly selected streets in Moradabad, North India. SUBJECTS AND METHODS: A total of 1806 subjects from North India (904 males and 902 females) age range 25-64 years. The survey methods were as follows: dietary diaries for 7 days food intake record; BP measurements; physician administered questionnaire and anthropometric measurements. Diagnosis of hypertension was based on new World Health Organization/International Society of Hypertension (WHO/ISH) criteria. Risk factors were assessed based on WHO guidelines. RESULTS: The prevalence of hypertension according to WHO/ISH criteria was 23.7% and by old WHO criteria 13.3%. In the WHO/ISH hypertensive group, isolated diastolic hypertension was present in 47.3% males and 40.6% females. Males have a slightly higher prevalence than females in the young age group, however, the prevalence rates are comparable in the older age groups. In both sexes, the prevalence rates and BP level increased with older age. Multivariate analysis revealed that age, higher body mass index, central obesity and higher socioeconomic status were independently and strongly associated with hypertension in both sexes. Higher dietary fat and salt intake and lower physical activity were weakly but significantly associated with hypertension. CONCLUSION: Association of higher socioeconmic status, higher body mass index and central obesity in North Indian adults with higher fat intake, lower physical activity and higher prevalence and level of hypertension indicate that these populations may benefit by decreasing the dietary fat intake and increasing physical activity, with an aim to decrease central obesity for decreasing hypertension in North Indians. 相似文献

OBJECTIVE: To analyze the prevalence of 11 modifiable behavioral risk factors, including multiple risk factors, among white, black, Asian and Pacific Islander, American Indian, and Hispanic women in the United States. DESIGN: We used Behavioral Risk Factor Surveillance System (BRFSS) data for 1992 to 1994 to examine risk factors (smoking; obesity; diabetes; heavy alcohol consumption; sedentary lifestyle; and inadequate use of seat belts, pap smears, consumption of fruits or vegetables, mammography and colorectal screening, and immunization), among women age 18 to 49, 50 to 64, and 65 and older. We also conducted a multiple regression analysis, comparing the odds of having either 1-2 versus 0 or 3 or more versus 0 risk factors among racial/ethnic groups, controlling for education and family income, to see if racial/ethnic differences can be attributed to socioeconomic differences. RESULTS: US women engage in a variety of behaviors that place them at risk for many causes of morbidity and mortality. Risk profiles vary substantially among racial/ethnic populations: Pacific Islanders have relatively low prevalences of most major risk factors, while blacks and American Indians have relatively high prevalences of many major risk factors. Prevalence differences among racial/ethnic populations are diminished but not eliminated when socioeconomic factors are accounted for. CONCLUSIONS: Appropriately designed programs to help women reduce their behavioral risk factors are needed. Action by health care providers, communities, and policy makers can substantially improve the health of women in the United States. 相似文献

The pathogenesis, treatment, and outcomes of type 1 and type 2 diabetes differ. Current surveys derive population-based estimates of diabetes prevalence by type using limited clinical information and applying classification rules developed in white populations. How well these rules perform when deriving similar estimates in African American populations is unknown. For this study, data were collected on a group of African Americans with diabetes who enrolled at the Diabetes Unit of Grady Memorial Hospital in Atlanta, Georgia, from April 16, 1991, to November 1, 1996. The data were used to develop some simple classification rules for African Americans based on a classification tree and a logistic regression model. Sensitivities and specificities, in which fasting C-peptide was used as the gold standard, were determined for these rules and for two current rules developed in mostly white, non-Hispanic populations. Rules that yielded precise (minimum variance unbiased) estimates of the prevalence of type 1 diabetes were preferred. The authors found that a rule based on the logistic regression model was best for estimating type 1 prevalences ranging from 1% to 17%. They concluded that simple classification rules can be used to estimate prevalence of diabetes by type in African American populations and that the optimal rule differs somewhat from the current rules. 相似文献

OBJECTIVE: To study the prevalence of cardiovascular risk factors in native urban Asian Indians and to look for the occurrence of clustering of these factors. RESEARCH DESIGN AND METHODS: The study included 953 subjects (532 men and 421 women), aged > or = 40 years, selected from a population survey for diabetes, which was conducted in 1994 in Madras, Tamil Nadu, India. Measurements of anthropometry, blood pressure, plasma lipid profile, glucose tolerance, plasma insulin response, and electrocardiogram were made. Based on the normal ranges derived from the population study, abnormalities in anthropometric values, plasma lipids, and insulin values were determined. Age-adjusted prevalences of the abnormalities were calculated using data from a 1991 urban census in Madras. The expected prevalences of the abnormalities in isolation and in combinations were calculated and compared with the corresponding observed figures. RESULTS: The prevalences of risk factors were in the order of central adiposity > dyslipidemia > hyperinsulinemia (2-h) > glucose intolerance > obesity > hypertension. The age-adjusted prevalence of coronary heart disease (CHD) was 3.9% (3.5% in men and 4.5% in women, NS), and T wave inversion was seen in an additional 10.3%. Isolated prevalences of all factors, except hypertension, were in lower frequency than expected. Combinations of each risk factor with one or two more risk factors occurred more frequently (1.3-4 times) than expected by chance. Impaired glucose tolerance and dyslipidemia showed association with hyperinsulinemia, whereas hypertension did not show such an association. CONCLUSIONS: Clustering of the cardiovascular risk factors or the components of insulin resistance syndrome occurs in the native Asian Indian population. This finding under-scores the need for preventive aspects of metabolic disorders and CHD. 相似文献

OBJECTIVE: To study the concordance between the 1997 American Diabetes Association (ADA) impaired fasting glucose (IFG) category with the World Health Organization (WHO) impaired glucose tolerance (IGT) status in a population with a high prevalence of diabetes. RESEARCH DESIGN AND METHODS: We analyzed the oral glucose tolerance tests (OGTTs) carried out at the Instituto Nacional de la Nutrición Salvador Zubiran (INNSZ) central laboratory from June to December 1997. We included patients with fasting plasma glucose (FPG) between 60 and 160 mg/dl. The results from the glucose tolerance test were selected as the gold standard. RESULTS: Among the 1,802 glucose tolerance test results available for analysis, 1,706 fulfilled the requirements to be included. Diabetes and IGT were remarkably more frequently diagnosed when the WHO criteria were applied. The new ADA criteria failed to diagnose 69% of WHO diabetic patients and the vast majority of WHO glucose-intolerant subjects. Using the new criteria, 82% were considered normal. Of the IFG subjects, 39% were classified as diabetic and 23% were normal according to the 2-h postchallenge glucose values. Only 37% of the IFG patients were, in fact, glucose intolerant according to the WHO criteria. CONCLUSIONS: Our results clearly show that the 1997 ADA criteria are less sensitive for diagnosing diabetes than OGTT-based WHO criteria. Even more important, there is poor agreement between the WHO category of IGT and the ADA category of IFG. 相似文献

This study investigated the prevalence of snoring and symptoms of sleep breathing-related disorders in the multi-ethnic population of Singapore (3 million people, comprising 75% Chinese, 15% Malay and 7% Indian). A multistaged, area cluster, disproportionate stratified, random sampling of adults aged 20-74 yrs was used to obtain a sample of 2,298 subjects (65% response), with approximately equal numbers of Chinese, Malay and Indian and in each 10 yr age group. An interviewer-administered field questionnaire was used to record symptoms of snoring and breathing disturbances during sleep witnessed by a room-mate and other personal and health-related data. The weighted point estimate (and 95% confidence interval) of the whole population prevalence of snoring was 6.8% (53-83). There were pronounced ethnic differences among Chinese, 6.2% (4.4-8.1); Malay, 8.1% (6.1-10.2) and Indian, 10.9% (85-13.4). The minimum whole population prevalence by the most restricted symptom criteria for defining sleep breathing-related disorder was 0.43% (0.05-0.8%). Similar marked ethnic differences in rates were observed using various symptom criteria. The ethnic differences in sleep breathing symptoms paralleled the differences in body mass index, neck circumference and hypertension, but statistically significant differences remained after adjustment for sex, age and these known associated factors. Marked ethnic differences in snoring and sleep breathing-related disorders were observed in Chinese, Malays and Indians in Singapore, which were only partly explained by known factors of sex, age and body habitus. 相似文献

PURPOSE: The Strong Heart Study is a study of cardiovascular disease and its risk factors among American Indian men and women aged 45-74 yr representative of 13 communities from Arizona (AZ), Oklahoma (OK), and North/South Dakota (N/SD). This investigation sought to characterize the amount and type of physical activity and to determine the association between activity and lipids in this population. METHODS: Total physical activity (occupational plus leisure) was assessed with a validated questionnaire. RESULTS: Men and women from OK (21 +/- 19 and 16 +/- 15 h.wk-1; respectively) and N/SD (23 +/- 21 and 17 +/- 17 h.wk-1; respectively) had activity levels that were similar if not lower than the U.S. population with the AZ communities (17 +/- 21 and 10 +/- 14 h.wk-1; respectively) being substantially lower than the other two communities. Total cholesterol (TC), high density lipoprotein cholesterol (HDL-c), and low density lipoprotein cholesterol (LDL-c) levels were lower than the U.S. population. CONCLUSIONS: For most of the population (diabetic men and nondiabetic men and women), activity was significantly associated (P < 0.05) with apolipoprotein (apo) AI after controlling for covariates. With levels of activity as low if not lower than the general U.S. population coupled with high prevalence of obesity and diabetes, efforts to increase physical activity in American Indians are warranted. Hopefully these increases in activity will result in favorable lipid changes as well as decreasing the risk of diabetes which is epidemic in these populations. 相似文献

This population based study was undertaken to ascertain the overall prevalence of diabetes mellitus (DM) and impaired glucose tolerance (IGT) in the elderly using the WHO criteria. The role of obesity in the development of DM or IGT has been investigated for both sexes per decade of age. Furthermore the potential for DM to increase with age, as has been suggested before, has been evaluated using the IGT as a proportion of total glucose intolerance (IGT/TGI) for the same parts of the tested sample. From the 647 persons registered as elderly people in a small town in northern Greece (total population 5875 people), 66 persons did not participate in this survey. Fifty-six subjects (9.7%) had previously diagnosed DM. The remainder were tested using fasting blood glucose measurements or an oral glucose tolerance test (OGTT). The prevalence of previously undiagnosed DM according to fasting blood glucose values or after 2 h of 75 g load values was 10.1% and 9.3%, respectively. Thus the overall prevalence of DM was 29.1% and of IGT was 15.1%. These data support an increased frequency of DM (65% previously undiagnosed) and IGT in the elderly, whereas this population's susceptibility seems to decline in the older groups for both sexes. Obesity remains a risk factor for DM and IGT particularly among the younger groups although its role has been found to decline with age. 相似文献

OBJECTIVE: To establish the prevalence of shoulder disease and chronic widespread pain in Pima Indians. METHODS: Cross sectional analyses of data from 4230 subjects for shoulder disease and 105 subjects for chronic widespread pain participating in population surveys RESULTS: The prevalence of shoulder disease was 4.4% (95% CI, 3.8-5.1), age-sex adjusted to the 1980 US census population. This is lower than in a study of Caucasians [prevalence ratio (PR) = 0.29, 95% CI, 0.20-0.42 for men and PR = 0.55, 95% CI, 0.41-0.73 for women]. Shoulder disease was associated with non-insulin-dependent diabetes mellitus (PR = 1.67, 95% CI, 1.19-2.36). No chronic widespread pain was identified (95% CI, 0-3.5%). CONCLUSION: Prevalence of these pain syndromes in Pima Indians is lower than in predominantly Caucasian populations. These findings suggest that these populations have different pain perception or different patterns of risk factors for these disorders. 相似文献

The aim of the present study was to determine the risk factors for Helicobacter pylori in a dyspeptic Malaysian population. A cross-sectional survey of 1060 consecutive patients presenting with dyspepsia at the Endoscopic Unit, University Hospital, Kuala Lumpur, Malaysia from January 1994 to July 1995 was undertaken. All patients answered a detailed questionnaire and underwent endoscopy, with two antral biopsies taken for diagnosis of H. pylori using a rapid urease test. An overall H. pylori prevalence of 49.0% was recorded. Helicobacter pylori prevalence in relation to the major endoscopic diagnoses were as follows: non-ulcer dyspepsia (NUD) 31.2%; duodenal ulcer (DU) 91.4%; and gastric ulcer (GU) 74.1%. The prevalence among the races were as follows: Malay 16.4%; Chinese 48.5%; and Indians 61.8%. Multiple logistic regression analysis identified the following as independent risk factors: > 45 years old 1.5 (1.1,2.0); male gender 1.6 (1.2,2.1); ethnic group: Chinese 2.5 (1.7,3.7); Indians 4.9 (3.2,7.5); level of education: low 2.3 (1.5,3.5); middle 1.7 (1.1,2.6); and smoking 1.6 (1.2,2.3). Analysis was also performed on DU, GU and non-UD patients separately; in both DU and GU patients, H. pylori prevalence was high regardless of age, sex, race or level of education. However, in DU patients, Indian race had an independent risk factor (Odds ratio = 7.8 (1.2,48.4)). The findings in the NUD group reflected the findings in the ?all patients' group; > 45 years old, male gender, Indian and Chinese race, and low level of education were also significant, independent risk factors. The overall differences in H. pylori prevalence between the different subgroups were mainly due to differences in the NUD group. The increased risk of H. pylori infection in Chinese and Indians points to either an inherent ethnic genetic predisposition or to socio-cultural practices peculiar to the particular race which may be responsible for transmission of the infection. 相似文献

This study examines the prevalence of, and risk factors for, diabetic retinopathy in Asian Indian, Chinese, and Creole Mauritians in whom there is an increasing prevalence of non-insulin-dependent diabetes mellitus (NIDDM). As part of a population-based survey on the Indian Ocean island of Mauritius in 1992, glucose tolerance was classified using a 75-g oral glucose tolerance test on 6,553 persons. Subjects with newly diagnosed (n = 358) or known diabetes (n = 388), and a random sample of one in four subjects with impaired glucose tolerance (n = 165), had stereoscopic 45 degrees retinal photographs taken of three fields in the right eye after mydriasis. Photographs were graded according to a modified version of the Airlie House criteria. The prevalence of nonproliferative and proliferative retinopathy was: 14.5% and 0.3%, respectively, in newly diagnosed diabetic subjects; 42.0% and 2.3%, respectively, in known diabetic subjects; and 9.1% and 0%, respectively, in persons with impaired glucose tolerance. Muslim Indians had the lowest prevalence of retinopathy (10.8% and 34.0% for new and known diabetes, respectively), but after adjusting for other factors, this was significantly different only to Creoles (18.8% and 53.8%, respectively). Univariate analysis revealed significant differences between diabetic subjects with and without retinopathy in mean age, body mass index, fasting and 2-hour plasma glucose levels, systolic and diastolic blood pressure, fasting triglycerides, serum creatinine, and urinary albumin levels. For known diabetes, mean duration of diabetes and the proportion using insulin were also greater in those with retinopathy. Multivariate analysis using logistic regression confirmed that increasing duration of diabetes, fasting plasma glucose, systolic blood pressure, and urinary albumin concentration, and decreasing body mass index, were independently associated with retinopathy. The high prevalence of diabetic retinopathy observed in all major ethnic groups in Mauritius portends a serious public health problem, given the relative recency of the NIDDM epidemic in that country and the limited resources for laser photocoagulation. Strategies to minimize this problem among those already known to have diabetes should include strict control of plasma glucose and blood pressure. 相似文献

A variant in prothrombin (clotting factor II), a G to A transition at nucleotide position 20210, has recently been shown to be associated with the prothrombin plasma levels and the risk of both venous and arterial thrombosis. The purpose of this study was to investigate the prevalence of carriership of this mutation in various populations. We combined data from 11 centres in nine countries, where tests for this mutation had been performed in groups representing the general population. We calculated an overall prevalence estimate, by a precision-weighted method, and, since the distribution of the prevalences did not appear homogeneous, by an unweighted average of the prevalences. We examined differences in the prevalences by geographical location and ethnic background as a possible explanation for the heterogeneity. Among a total of 5527 individuals who had been tested, 111 heterozygous carriers of the 20210A mutation were found. The prevalence estimates varied from 0.7 to 4.0 between the centres. The overall prevalence estimate was 2.0 percent (CI95 1.4-2.6%). The variation around the summary estimate appeared more than was expected by chance alone, and this heterogeneity could be explained by geographic differences. In southern Europe, the prevalence was 3.0 percent (CI95 2.3 to 3.7%), nearly twice as high as the prevalence in northern Europe (1.7%, CI95 1.3 to 2.2%). The prothrombin variant appeared very rare in individuals from Asian and African descent. The 20210A prothrombin variant is a common abnormality, with a prevalence of carriership between one and four percent. It is more common in southern than in northern Europe. Since this distribution within Europe is very different to that of another prothrombotic mutation (factor V Leiden or factor V R506Q), founder effects are the most likely explanation for the geographical distribution of both mutations. 相似文献

Until recently, Type II diabetes was considered rare in children. The disease is, however, increasing among children in populations with high rates of Type II diabetes in adults. The prevalence of Type II diabetes was determined in 5274 Pima Indian children between 1967 and 1996 in three 10-year time periods, for age groups 5-9, 10-14 and 15-19 years. Diabetes was diagnosed using World Health Organisation criteria, based on an oral glucose tolerance test. The prevalence of diabetes increased over time in children aged 10 years and over: in boys from 0 % in 1967-1976 to 1.4% in 1987-1996 in the 10-14 year old age group, and from 2.43% to 3.78% for age group 15-19 and in girls from 0.72 % in 1967-1976 to 2.88 % in 1987-1996 in the 10-14 year old age group, and from 2.73 % to 5.31 % for age group 15-19 years. Along with the increase in the prevalence of Type II diabetes (p < 0.0001), there was an increase in weight (calculated as percentage of relative weight, p < 0.0001), and in frequency of exposure to diabetes in utero (p < 0.0001). The increasing weight and increasing frequency of exposure to diabetes in utero accounted for most of the increase in diabetes prevalence in Pima Indian children over the past 30 years. Type II diabetes is now a common disease in American Indian children aged 10 or more years and has increased dramatically over time, along with increasing weight. A vicious cycle related to an increase in the frequency of exposure to diabetes in utero appears to be an important feature of this epidemic. 相似文献

In their recent article, N. Spillane and G. Smith (see record 2007-06095-002) suggested that reservation-dwelling American Indians have higher rates of problem drinking than do either non–American Indians or those American Indians living in nonreservation settings. These authors further argued that problematic alcohol use patterns in reservation communities are due to the lack of contingencies between drinking and “standard life reinforcers” (SLRs), such as employment, housing, education, and health care. This comment presents evidence that these arguments were based on a partial review of the literature. Weaknesses in the application of SLR constructs to American Indian reservation communities are identified as is the need for culturally contextualized empirical evidence supporting this theory and its application. Cautionary notes are offered about the development of literature reviews, theoretical frameworks, and policy recommendations for American Indian communities.

BACKGROUND: We aimed to compare the prevalence of abnormal glucose tolerance identified by the 1985 WHO and the 1997 American Diabetes Association (ADA) diagnostic categories based on information collected in the Cardiovascular Health Study, an epidemiological study of elderly people. METHODS: We measured glucose concentrations during fasting and 2 h after a 75 g oral glucose-tolerance test in participants aged 65-100 years in the Cardiovascular Health Study. From a 1989 cohort, we analysed the glucose measurements of 4515 individuals without a previous diagnosis of diabetes and of 262 additional measurements from an African-American cohort recruited in 1992-93. FINDINGS: In the 1989 cohort, the prevalence of untreated diabetes with ADA diagnostic fasting criteria was 7.7% versus a prevalence of 14.8% by the WHO criteria. In the African-American cohort, the prevalence of untreated diabetes was 2.7% with ADA criteria and 11.8% with WHO criteria. 3509 (77.7%) of the 4515 participants in the 1989 cohort had normal glucose concentrations according to ADA fasting criteria, compared with 2401 (53.2%) according to WHO criteria. In the African-American cohort, the corresponding numbers were 239 (91.2%) versus 153 (58.4%). All differences in prevalence of abnormal glucose tolerance between ADA and WHO classifications were significant (p<0.0001). INTERPRETATION: Among elderly individuals, there was a significant difference in the prevalence of diabetes identified by the WHO diagnostic criteria based on oral glucose-tolerance test and the ADA fasting criteria. Consequently, many individuals currently classified as non-diabetic according to ADA criteria would previously have had a diagnosis of diabetes according to WHO criteria. Longitudinal studies are needed to assess the value of the criteria in the identification of individuals at increased risk of diabetes-associated chronic complications. 相似文献

OBJECTIVE: Recently, the American Diabetes Association (ADA) has proposed revised diagnostic criteria for diabetes. Lowering of the fasting plasma glucose (FPG) cutoff value is intended to reduce the discrepancy with the 2-h plasma glucose (PG) cutoff value and to encourage the use of FPG. We have applied these new criteria to data collected from a population-based prevalence survey in Hong Kong Chinese subjects of working age. RESEARCH DESIGN AND METHODS: The results of 1,513 oral glucose tolerance tests (OGTTs) from a previously published prevalence survey of glucose intolerance and cardiovascular risk factors in a Hong Kong Chinese working population were reexamined using the new criteria. Of the 1,513 subjects, 27 had a known history of diabetes. Of the remaining 1,486 subjects, 228 were also selected randomly for a second OGTT without prior knowledge of the result of the first test. RESULTS: After exclusion of the 27 subjects with a known history of diabetes, the crude prevalence of diabetes was 2.83% (n = 42) when the World Health Organization's (WHO) criteria were applied. When the criterion of FPG > or = 7.0 mmol/l was used, as recommended by the ADA, the prevalence of diabetes was 1.41% (n = 21). Twenty-nine subjects (1.95%) with FPG < 7.0 mmol/l had a 2-h PG > or = 11.1 mmol/l. Eight subjects (0.53%), previously without a diagnosis of diabetes according to the WHO criteria (FPG < 7.8 mmol/l and 2-h PG < 11.1 mmol/l), had FPG between 7.0 and 7.8 mmol/l and were classified as having diabetes by the ADA criteria. This classification gave a net change of -1.42% in the prevalence of diabetes between the use of FPG > or = 7.0 mmol/l alone and the use of WHO criteria. Among the 1,486 subjects with no known history of diabetes, those classified as having diabetes according to the ADA FPG criterion alone had higher HbA1c and fructosamine levels than diabetic subjects defined by the WHO criteria. Of the 228 subjects for whom two FPG measurements were available, those who had consistent definitions (diabetes, impaired fasting glucose, normal fasting glucose) on both occasions were considered to have reproducible tests, giving an overall reproducibility of 90.8% (207 of 228). CONCLUSIONS: Compared with the WHO criteria, the use of FPG to diagnose diabetes, as recommended by the ADA, was a more reproducible test and identified those subjects who had a greater degree of hyperglycemia. Although lowering of the cutoff value from 7.8 to 7.0 mmol/l increased the number of diagnoses among subjects with low FPG, the omission of the 2-h PG would lead to fewer subjects having their diabetes diagnosed. 相似文献

Impaired glucose tolerance (IGT), which is asymptomatic and requires a glucose tolerance test for detection, is a well-known risk factor for diabetes mellitus. Outside the research setting it is rarely identified in people who lack specific risk factors for diabetes except during pregnancy, at which time screening with an oral glucose challenge is a routine procedure. A 75-g oral glucose tolerance test was performed during the latter part of pregnancy or during a routine epidemiology survey in 15-39-year-old Pima Indian women with no history of abnormal glucose tolerance. Those with IGT by World Health Organization criteria were included in this study. Diabetes incidence in women was compared between those whose IGT was first detected during pregnancy and those who were not pregnant when IGT was first recognized. Seventeen of 73 pregnant women and 114 of 244 non-pregnant women developed diabetes within 10 years. When controlled for plasma glucose concentration, age, body mass index, parity and duration of follow-up, those who were not pregnant were at higher risk of developing diabetes than those who were pregnant (hazard rate ratio = 1.71, 95% confidence interval = 1.01-2.91). Previous studies had reported that women with IGT during pregnancy are at higher risk of diabetes than women with normal glucose tolerance. This study suggests that women with IGT during pregnancy are at lower risk than non-pregnant women with a similar plasma glucose concentration who, in the clinical setting, are likely to remain unrecognized. 相似文献
