DM BoD China v US
• In absolute terms – 113.9 million in China (largest in the world) – 1 in 4 of all cases worldwide are in China – 29.1 million in US
• In relaKve terms – 11.6% of Chinese adults in 2010 – 9.3% of US populaKon in 2012 (12.3% of people aged ≥20 )
Xu et al. JAMA. 2013;310(9):948-‐59 2014 NaKonal Diabetes StaKsKcs Report, CDC IDF Diabetes Atlas Sixth EdiKon Update, InternaKonal Diabetes FederaKon 2014
• One order of magnitude increase in prevalence • 1980: <1% • 1994: 2.5% • 2010: 11.6%
• Pre-‐diabetes • Prevalence of 50.1% = 493.4 million • Based on ADA 2010 criteria
• impaired fasKng glucose, impaired glucose tolerance, or raised HbA1c

An ongoing challenge • Develop diabetes at younger age and lower BMI
– High prevalence of diabetes despite lower levels of obesity – “normal-‐weight metabolically obese”
• NutriKon transiKon – Fast food and refined carbohydrates (e.g. white rice)
• Economic development and urbanizaKon – Sedentary occupaKons in a service-‐led, high value-‐added economy
• Life style trends – Reduced physical acKvity – High smoking rates (52.9% of men)
• Macro impact of socioeconomic development

“Rule of Halves”
• 69.9% are unaware of their diabetes status – US: 27.8%
• Only 25.8% are receiving treatment for diabetes – Of which, only 39.7% had adequate glycaemic control (HbA1c below 7.0%)
• Underdeveloped and unequal health care access • Diabetes treatment guidelines largely based on evidence from non-‐Asian populaKons
Xu et al. JAMA. 2013;310(9):948-‐59 2014 NaKonal Diabetes StaKsKcs Report, CDC
Economic Cost
• China spends RMB 173.4b (USD 25 billion) annually on direct diabetes treatment – 13% of total medical spending – US: direct medical costs of $176b plus indirect costs of $69b
• Projected annual cost of RMB 360b (USD 60b) by 2030

Incidence and Prevalence
• Counted as an incident case in the year of diagnosis date, then excluded from the numerator and denominator for subsequent years
• PaKents with a diagnosis date before Jan 1, 2007 were classed as pre-‐exisKng diabetes and excluded from the incidence figures.
• New cases were assumed to have occurred at the beginning of each calendar year; thus, the person-‐Kme at-‐risk was: (Mid-‐year populaKon aged 20y or over – Cases of diabetes on January 1 of that year) x 1 year
• Prevalence was calculated as the number of diabetes paKents alive on January 1 divided by the Hong Kong populaKon esKmate (aged 20y or over) on January 1
• PopulaKon esKmates of residents based on Government Census & StaKsKcs Department published figures

– EsKmated prevalence (by populaKon-‐based tesKng) of 11.6% among mainland Chinese adults in 2010 – Prevalence of 14.3% in urban developed areas – 69.9% unaware of their diabetes status
• Hong Kong is the most and longest developed Chinese city – ConservaKvely assuming 27.8% are unaware as per US

Measuring gains in health status
• Assessed changes in mean modifiable 5-‐year risk using UKPDS and Hong Kong-‐specific (CUHK) risk predicKon models
• Compared across four 2-‐year periods: 2006-‐07, 2008-‐09, 2010-‐11 and 2012-‐13
• Calculated the latest risk esKmates in each period keeping age (and diabetes duraKon) at baseline values
• Thus the difference between risk esKmates reflected changes in risk factors potenKally ajributable to clinical care (modifiable risk)

Known caveats of risk predicKon models
• Original Framingham CHD risk assessment tools overesKmated the risk of CHD for Chinese populaKons
• UKPDS overesKmated coronary heart disease and stroke risk in type 2 diabetes mellitus for Chinese populaKons
• CUHK models suffered from co-‐linearity and lack of widely available clinical measurements
• We are currently working on calibraKng our own risk predicKon esKmates
Liu J. et al., JAMA. 2004 Jun 2;291(21):2591-‐9. Yang X. et al., Am J Cardiol. 2008 Mar 1;101(5):596-‐601. Yang X. et al, Diabetes Care. 2007 Jan;30(1):65-‐70.
Defining subcohorts
• Divided the diabetes paKents based on the year of diagnosis into four subcohorts: – Pre-‐2006 (defined by full data availability) – 2006-‐2007 – 2008-‐2009 – 2009-‐2010
• Divided up paKents based on age of diabetes onset: – Under vs at least 60y at onset

Net value of benefits and spending
• We are analyzing the uKlizaKon data to empirically esKmate the value of saved medical treatment costs from avoiding diabetes-‐related complicaKons such as CHD and stroke.
• We will also esKmate the monetary value of improved survival based on different assumpKons of the value of a life-‐year.
