OBJECTIVE — To estimate the prevalence of diabetes and the number of people with dia-betes who are ^20 years of age in all countries of the world for three points in time, i.e., theyears 1995, 2000, and 2025, and to calculate additional parameters, such as sex ratio, urban-rural ratio, and the age structure of the diabetic population.
RESEARCH DESIGN AND METHODS — Age-specific diabetes prevalence estimateswere applied to United Nations population estimates and projections for the number of adultsaged 5:20 years in all countries of the world. For developing countries, urban and rural pop-ulations were considered separately.
RESULTS — Prevalence of diabetes in adults worldwide was estimated to be 4.0% in 1995and to rise to 5.4% by the year 2025. It is higher in developed than in developing countries.The number of adults with diabetes in the world will rise from 135 million in 1995 to 300 mil-lion in the year 2025. The major part of this numerical increase will occur in developing coun-tries. There will be a 42% increase, from 51 to 72 million, in the developed countries and a170% increase, from 84 to 228 million, in the developing countries. Thus, by the year 2025,>75% of people with diabetes will reside in developing countries, as compared with 62% in1995. The countries with the largest number of people with diabetes are, and will be in the year2025, India, China, and the U.S. In developing countries, the majority of people with diabetesare in the age range of 45-64 years. In the developed countries, the majority of people with dia-betes are aged ^65 years. This pattern will be accentuated by the year 2025. There are morewomen than men with diabetes, especially in developed countries. In the future, diabetes willbe increasingly concentrated in urban areas.
CONCLUSIONS — This report supports earlier predictions of the epidemic nature of dia-betes in the world during the first quarter of the 21st century. It also provides a provisional pic-ture of the characteristics of the epidemic. Worldwide surveillance of diabetes is a necessaryfirst step toward its prevention and control, which is now recognized as an urgent priority.

I n 1993, the World Health Organization(WHO) Ad Hoc Diabetes Reporting Grouppublished standardized global estimates
for the prevalence of diabetes and impairedglucose tolerance in adults, based on datafrom 75 communities in 32 countries (1).
These estimates provided, for the firsttime, comparable information on theprevalence of abnormal glucose tolerancefrom many populations worldwide. How-ever, they did not meet the needs of thosewho frequently refer to the WHO diabetes

program for information on the number ofpeople with diabetes in a particular coun-try/community, nor did they take accountof future trends in the burden of diabetes.
Therefore, a further study has nowbeen undertaken that links data from theglobal database collected by WHO withdemographic estimates and projectionsissued by the United Nations to estimatethe number of people with diabetes in allcountries of the world for three points intime, i.e., the years 1995, 2000, and 2025.In addition, the data have been analyzed interms of certain additional parameters,such as sex ratio, urban-rural ratio, and theage structure of the diabetic population.
The principal purpose of the projectwas to assemble numerical estimates andprojections for the frequency of diabetes inall countries as a primary source of infor-mation and as an aid to planning healthcare and public health interventions inWHO's member states.
RESEARCH DESIGN ANDMETHODS — This study is based on aset of 5-year age- and sex-specific estimatesof diabetes prevalence from rural and urbanareas of various countries. Criteria for inclu-sion were 1) a valid and apparently unbi-ased population sample and 2) a diagnosisof diabetes made according to the recom-mendations of recent WHO expert groups(2,3), i.e., a venous plasma glucose concen-tration of ^ 11.1 mmol/1 (or its equivalent)2 h after a 75-g oral glucose challenge. Stud-ies using only fasting blood glucose testingwere excluded. The estimates were drawnfrom the studies listed in the earlier report(1) with the addition of new survey datafrom China (4), Indonesia (5), Japan (6),Pakistan (7), and Uzbekistan (8). Thesedata were then applied to demographic esti-mates for the world's population issued bythe United Nations Population Division (9).
In accordance with United Nationsconvention, Europe (including the formersocialist economies), North America, Aus-tralia, New Zealand, and Japan were con-sidered "developed" countries, with allother countries designated as "developing"countries. For regional groupings, theaggregations proposed by the World Devel-opment Report 1993 were adopted (10).

Because the great majority of peoplewith diabetes are adults, the study wasrestricted to subjects aged ^20 years. For thedeveloped countries, risk factors were notconsidered to differ markedly in rural andurban areas, and estimates were appliednationally. However, for developing coun-tries, rural and urban areas were consideredseparately, since prevalence is known to dif-fer markedly with differences in diet, physi-cal exercise, and other socioeconomic factors.Estimates for present and future urbanizationpatterns are also available from the UnitedNations Population Division (11,12). Wheneither rural or urban prevalence data wereunavailable, the urban rate was generallyassumed to be twice the available rural esti-mate, or the rural estimate was taken as one-half the available urban estimate. That thisrelation holds for most populations in devel-oping countries is evident from rural-urbancomparisons of the age-standardized esti-mates presented in the earlier report (1). Forcountries lacking valid prevalence estimates,extrapolation from the nearest or socioeco-nomically and ethnically most similar coun-try was performed. A listing of the dataapplied to each country's demographic esti-mates is given in APPENDIX l.
The assumption underlying the studymethodology was that, in addition to eth-nicity the size, sex distribution, age struc-ture, and degree of urbanization determinethe present and future frequency of diabetesin countries. Thus, for estimations for 1995,2000, and 2025, the baseline age- and sex-specific prevalence estimates within ruraland urban areas were maintained as a con-stant (i.e., inclusion in the models of popu-lation growth, aging, and urbanization wasconsidered sufficient to capture present andfuture trends in diabetes frequency).
Not all data sets included the full agerange under consideration (^20 years).Therefore, for each source of data, a logisticregression analysis was performed to esti-mate the relationship of age to the probabil-ity of having diabetes. The predictedprobability was then used as an estimate ofthe missing age-specific prevalence(s) so thatall the age-groups of interest, from 20-24years to ^80 years, could contribute to themodels. This method also resulted in a sta-bilization of rates when numbers from theraw data were quite sparse.
In certain cases, combinations of datawere made. For Novosibirsk, data for malesand females were combined because ofsmall numbers. For Israel, data from foursurveys were combined to give national

estimates. For China, data from the 1994National Diabetes Survey of 250,000 sub-jects in 16 provinces were aggregated intorural and urban estimates. For the U.K.,two surveys were combined. For the U.S.,National Health and Nutrition Examina-tion Survey II data were used for ages20-74 years, and Rancho Bernardo datawere used for older subjects.
RESULTS — The detailed numerical esti-mates and other parameters of interest arepresented for all countries and regions for theyears 1995,2000, and 2025 in APPENDIX 2.
DemographyThe size of the world's adult population(aged ^20 years) is shown by year andregion in Fig. 1. It can be seen that for thedeveloped countries, total population sizewill remain relatively stable, with an 11%increase from 1995 to 2025 of ~ 1 billion.
For the developing countries, the increasewill be around 80%, from ~2.5 billion in1995 to >4 billion in 2025. It is thisincrease that will determine the ~60%growth of the world's adult population as awhole over these 30 years, from >3 billionto >5 billion.
The rise in adult population size will bemodest in the former socialist economies ofEurope (FSE) (5%) and the establishedmarket economies (EME) (11%); moderatein China (39%); -80% in India, other Asiaand islands (OAI), and Latin America andthe Caribbean (LAC); and >100% in sub-Saharan Africa (SSA) and the Middle East-ern crescent (MEC).
Prevalence of diabetesThe prevalence of diabetes in adults aged^20 years is shown by year and region inFig. 2. Between 1995 and 2025 there willbe a 35% increase in the worldwide preva-

lence of diabetes, from 4.0 to 5.4%. Preva-lence is higher in developed than in devel-oping countries and will remain so in 2025.However, the proportional increase will begreater in the developing countries. Indeveloped countries, the increase in preva-lence will be 27%, from 6.0 to 7.6%. Indeveloping countries, the increase will be48%, from 3.3 to 4.9%.
The highest increases in prevalencebetween 1995 and 2025 will be for China(68%) and India (59%). LAC and OAI willboth experience a 41% increase, and MECwill experience a 30% increase. The increasewill be lowest in FSE (26%) and EME (28%).
Numerical estimatesThe number of adult people with diabetesis shown by year and region in Fig. 3. Thenumber of adults with diabetes in theworld is estimated to increase by 122%,from 135 million in 1995 to 300 million in2025. There will be a 42% increase, from51 million to 72 million, in the developedcountries. In the developing countries,
there will be a 170% increase, from 84 mil-lion to 228 million. Thus, by the year 2025,over 75% of all people with diabetes will bein the developing countries, as comparedwith 62% in 1995.
The greatest increases will be seen inIndia (195%, from 19 million to 57 mil-lion), MEC (193%, from 18 million to 54million), and SSA (185%, from 3 million to8 million). The increase will be over 150%in OAI (from 12 million to 32 million) andLAC (from 15 million to 39 million). InChina there will be a 134% increase (from16 million to 38 million). The smallestincreases will occur in FSE (33%, from 17million to 22 million) and EME (46%, from34 million to 50 million).
The "Top 10" countries of the world, interms of the number of people with diabetes,are shown for 1995 and 2025 in Table 1. Atboth points in time, the three countries withthe largest number of people with diabetesare India, China, and the U.S. For 1995, oth-ers in the Top 10 are the Russian Federation,Japan, Brazil, Indonesia, Pakistan, Mexico,
and the Ukraine. For 2025, the others in theTop 10 are Pakistan, Indonesia, Russian Fed-eration, Mexico, Brazil, Egypt, and Japan.Thus, there will be a tendency for certaindeveloping countries to move up the list andfor certain industrialized countries to movedown it. In both time periods, the Top 10countries will account for approximatelytwo-thirds of all diabetes in the world.
Age structure of the diabeticpopulationThe number of diabetic subjects in three ageranges, i.e., 20-44 years, 45-64 years, and^65 years, is shown by region of the worldfor the years 1995 and 2025 in Fig. 4.
The age structure of the diabetic pop-ulations of developed and developingcountries are markedly different. For thedeveloped countries, the oldest age-grouphas the largest number of people with dia-betes in 1995 and will experience the great-est increase in numbers by the year 2025.However, for the developing countries, the45- to 64-year-old age-group contained thelargest number of people with diabetes in1995, and this tendency will be furtheraccentuated by the year 2025. The agestructure of the world total follows thetrend for developing countries.
Regionally, three distinct patternsemerge. For SSA, the greatest numbersand the greatest increases are in the twoyounger age-groups, with only a small pro-portion of subjects in the oldest age range.For LAC, MEC, China, India, and OAI, themajority of people with diabetes are andwill be in the middle age range. For EMEand FSE, there are relatively few youngpeople with diabetes, and the majority ofpeople with diabetes are presently, and willbe in 2025, over 65 years of age.
Male/female diabetes ratioThe ratio of the number of adult male andfemale people with diabetes is shown byyear and region in Fig. 5. For 1995 for theworld as a whole, there were more womenthan men with diabetes (73 vs. 62 million).The female excess is pronounced in thedeveloped countries (31 vs. 20 million),but in the developing countries, there areequal numbers of men and women withdiabetes (42 million in each case). Region-ally, there is a marked female excess in FSE(12 million vs. 5 million) and LAC (9 vs. 6million). There is a moderate female excessin EME (20 vs. 15 million) and China (9 vs.7 million). There is approximate parity inthe ratio in MEC (9 million in each case)

and OAI (6 million in each case). There is amale excess in India (11 vs. 8 million) andinSSA(1.8vs. 1.1 million).
By the year 2025, the worldwidefemale/male excess is estimated to bereduced somewhat (to 159 vs. 141 million).The female excess will decrease in FSE andEME but increase slightly in China, LAC,and MEC. The male excess will decrease inIndia, but it will increase in SSA.
Urban/rural diabetes ratioFor developing regions of the world, thestudy design permitted the calculation ofthe ratio of the frequency of diabetes inurban and rural areas (Fig. 6). Apart fromChina and SSA, all regions had at least asmany cases in urban as in rural areas in1995. By 2025, there will be a considerableexcess of diabetes in the urban areas. Themost extreme example is LAC (with a 12-fold excess), followed by MEC (with a 4-
fold excess) and India (with a 3-foldexcess). For developing countries as awhole, the urban/rural ratio in diabetes fre-
quency is predicted to rise from 1.6 in1995 to 3.3 in 2025.
CONCLUSIONS — The results of thisstudy suggest that for the world as a whole,between the years 1995 and 2025, theadult population will increase by 64%,prevalence of diabetes in adults willincrease by 35%, and the number of peo-ple with diabetes will increase by 122%.For the developed countries, there will bean 11% increase in the adult population, a27% increase in the prevalence of adultdiabetes, and a 42% increase in the num-ber of people with diabetes. For the devel-oping countries, there will be an 82%increase in the adult population, a 48%increase in the prevalence of adult dia-betes, and a 170% increase in the numberof people with diabetes.
Because of a lack of suitable survey data,many extrapolations were necessary in thisstudy (all of SSA was estimated based on thedata from Tanzania). Even when a survey ina particular country was available, its find-ings may not necessarily have been nation-ally representative (it is unlikely that thereare three times as many men as women withdiabetes in Australia and New Zealand; thisresult was due to a relatively high number ofelderly diabetic men being identified in theonly available Australian study).
Additional caution should be expressedover the fact that some of the studies wereconducted in the 1980s and therefore maynot reflect the current situation. Somerecent reports have suggested quite sub-stantial increases in prevalences in countriessuch as India (13) and Korea (14). A recentreport from Nigeria (15), as well as clinicalobservation, also suggests that diabetes is

now more common in SSA than was previ-ously thought. Therefore, both national andregional figures for SSA may be underesti-mated.
For all of these reasons, too muchemphasis should not be placed on the fig-ures for individual countries. However,they do provide a useful starting point fornational situational analysis.
Three previous studies have estimatedthe number of people with diabetes in theworld. Although they used different sourcesof demographic data, they drew to a largeextent on the same prevalence data as thepresent project, and estimates of currentprevalence are quite comparable. It shouldbe noted that all four studies have relied onfield survey data for the estimation of preva-lence. Therefore, the numerical estimatesderived therefrom represent all people withdiabetes in the community, including bothknown and undiagnosed cases.
As compared with our global estimate of
135 million adults with diabetes for 1995,Murray and Lopez (16) estimated 118 mil-lion cases at all ages for 1990. McCarty andZimmet (17) estimated 110 million cases atall ages for 1994. Most recently, Amos et al.(18)—in a revision of the earlier McCartyand Zimmet report—estimated 118 millioncases at all ages for 1995. Comparing the1995 and 2000 country estimates of Amoset al. and the present study, in most casesthere is good agreement, although there area small number of important differences thatbear further examination.
McCarty and Zimmet, and subse-quently Amos et al., also attempted to makeprojections of diabetes frequency into thefuture. However, they did not incorporateprojected changes in patterns of urbaniza-tion directly into their models, as was donein the present study Instead, they hypothe-sized that in general, populations wouldmove toward progressively higher preva-lences of diabetes in the future. They first
examined all available prevalence rates for anethnic group, and then for each country,they selected the "most appropriate" higherrate based on predicted future gross nationalproduct and urbanization of each country.The higher age-specific prevalence estimateswere then applied to a projected national agedistribution. Using this procedure, Amos etal. estimated a world total of 147 millioncases for the year 2000 (as compared withour estimate of 154 million) and 221 millioncases for the year 2010. Thus, the projec-tions of Amos et al. yield an average annualincrement to the worlds diabetic populationof 5.8 million people for the years1995-1999 and of 7.4 million people for theyears 2000-2010. Our apparently moreconservative approach yields an averageannual growth of the worlds diabetic popu-lation of 3.8 million people for the years1995-1999 (starting from a higher 1995baseline figure) and of 5.8 million people forthe years 2000-2025. These alternatives,essentially the result of adopting "pes-simistic" or "optimistic" scenarios, probablyform useful boundaries for the likely burdenof diabetes during the first years of the 21stcentury Thus, they may be viewed as com-plementary to one another.
The failure to include subjects <20years of age in the present study should notbe taken as ignoring the importance andseverity of diabetes in childhood and ado-lescence. It is simply a reflection of the factthat their inclusion would have had littleeffect on the numerical estimates. Of the 118million cases estimated by Murray andLopez for 1990, only 214,000, or 0.2%,were <15 years of age. This suggests thatfrequency of diabetes in adults is a close andefficient proxy for global frequency of dia-betes at all ages.
The division of countries into "devel-oped" and "developing" groups is some-what arbitrary and is unduly simplistic,given that many developing countries havecomplex infrastructures and considerableeconomic potential. However, it does serveto differentiate those countries that havebeen industrialized for some time from thenewly emerging economies and those yet toexperience such changes. Clearly, there areclose links between socioeconomic transi-tion and epidemiological transition.
The much greater predicted number ofmiddle-aged (45-64 years) than elderly(^65 years) people with diabetes in thedeveloping countries is important. Suchsubjects will have to endure the conditionduring some of the most productive years

of their lives. They will also have moreyears of life to develop the chronic compli-cations of diabetes than will the generallyelderly diabetic population of the industri-alized countries. This will have majorimplications with respect to health careneeds, resource utilization, and cost.
The fact that there are more womenthan men with diabetes in many countries isalso notable. For the developed countries, alikely explanation is the greater longevity ofwomen. However, in the developing coun-tries, diabetes is more common in the mid-dle-aged than the elderly (Fig. 4), underwhich circumstances the previous explana-tion is less likely In this case, it may be dif-ferential distribution of risk factors—especially diet, physical inactivity, and cen-tral obesity—in men and women that maydetermine the male/female ratio. If so, theratio may have public health, as well ashealth planning, significance.
The increasing concentration of dia-betes in urban areas of developing coun-tries, which may be largely accounted forby the rapid growth in size of the majorurban conglomerates of developing coun-tries, as well as by the aging of their popu-lations, should also be borne in mind whenplanning future health care systems.
In summary, this report supports ear-lier predictions of the epidemic nature ofdiabetes in the world during the first quar-ter of the 21st century. It also provides aprovisional picture of the characteristics ofthe epidemic. The database is a contribu-tion to an ongoing process of worldwidesurveillance of diabetes, its complications,and related disorders, which recently ledthe WHO to recommend prevalence ofdiabetes as one of the "basic health indica-tors" for its member states (19). Such sur-veillance is a first step toward the integratedprevention and control of diabetes andother noncommunicable diseases, whichis now recognized as an urgent priority fornational and international health authori-ties (20).
