Kuek T. Type 2 Diabetes Prevalence, Control and Management within Fiji,Kiribati, Samoa, the Solomon Islands, Tonga, and Vanuatu: A ScopingReview with a Systematic Approach. Curr Diabetes Rev 2024; 20:e220124225914. [PMID: 38258764 DOI: 10.2174/0115733998260306231025151814] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/18/2023] [Revised: 08/25/2023] [Accepted: 09/15/2023] [Indexed: 01/24/2024]
Abstract
BACKGROUND Type 2 diabetes (T2D) causes significant morbidity and is disproportionately prevalent in Pacific Island Countries (PICs). The socio-political demographics of PICs are rapidly changing, and health services must adapt to match the needs of their population. OBJECTIVES The objective of this study was to review the literature published within the last 15 years relating to T2D prevalence, control, and management, with a specific focus on targetable areas for future funding and research projects. METHODS This review was conducted using the PRISMA guidelines. Inclusion criteria were: discussion on T2D in the six PICs. Results were limited to those published between 1st January, 2006, and 27th July, 2023. RESULTS A total of 6,640 publications were retrieved, and 110 met the inclusion criteria. Nineteen additional studies were identified through hand-searching. T2D prevalence differed between countries but was predicted to increase in the coming decades, with projections of up to 31.2% by 2030 in Tonga. Factors associated with T2D varied between countries, including Indian-Fijian ethnicity in Fiji and tuberculosis in Kiribati. Control was generally poor, with high rates of undiagnosed diabetes and microvascular complications. Epidemiological data was limited in some cases, as was information describing the structure and function of diabetes services. CONCLUSION The prevalence, control, and management of T2D varied between Fiji, Kiribati, Samoa, the Solomon Islands, Tonga, and Vanuatu. Significant gaps remain in the data describing these domains; however, there are clearly targetable areas for future research and diabetes management programs.

Figueroa CA, Linhart CL, Dearie C, Fusimalohi LE, Kupu S, Morrell SL, Taylor RJ. Effects of inappropriate cause-of-death certification on mortality from cardiovascular disease and diabetes mellitus in Tonga. BMC Public Health 2023; 23:2381. [PMID: 38041110 PMCID: PMC10691179 DOI: 10.1186/s12889-023-17294-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2023] [Accepted: 11/22/2023] [Indexed: 12/03/2023] Open
Abstract
BACKGROUND Cardiovascular disease (CVD) and diabetes mellitus are major health issues in Tonga and other Pacific countries, although mortality levels and trends are unclear. We assess the impacts of cause-of-death certification on coding of CVD and diabetes as underlying causes of death (UCoD). METHODS Tongan records containing cause-of-death data (2001-2018), including medical certificates of cause-of-death (MCCD), had UCoD assigned according to International Classification of Diseases 10th revision (ICD-10) coding rules. Deaths without recorded cause were included to ascertain total mortality. Diabetes and hypertension causes were reallocated from Part 1 of the MCCD (direct cause) to Part 2 (contributory cause) if potentially fatal complications were not recorded, and an alternative UCoD was assigned. Proportional mortality by cause based on the alternative UCoD were applied to total deaths then mortality rates calculated by age and sex using census/intercensal population estimates. CVD and diabetes mortality rates for unaltered and alternative UCoD were compared using Poisson regression. RESULTS Over 2001-18, in ages 35-59 years, alternative CVD mortality was higher than unaltered CVD mortality in men (p = 0.043) and women (p = 0.15); for 2010-18, alternative versus unaltered measures in men were 3.3/103 (95%CI: 3.0-3.7/103) versus 2.9/103 (95%CI: 2.6-3.2/103), and in women were 1.1/103 (95%CI: 0.9-1.3/103) versus 0.9/103 (95%CI: 0.8-1.1/103). Conversely, alternative diabetes mortality rates were significantly lower than the unaltered rates over 2001-18 in men (p < 0.0001) and women (p = 0.013); for 2010-18, these measures in men were 1.3/103 (95%CI: 1.1-1.5/103) versus 1.9/103 (95%CI: 1.6-2.2/103), and in women were 1.4/103 (95%CI: 1.2-1.7/103) versus 1.7/103 (95%CI: 1.5-2.0/103). Diabetes mortality rates increased significantly over 2001-18 in men (unaltered: p < 0.0001; alternative: p = 0.0007) and increased overall in women (unaltered: p = 0.0015; alternative: p = 0.014). CONCLUSIONS Diabetes reporting in Part 1 of the MCCD, without potentially fatal diabetes complications, has led to over-estimation of diabetes, and under-estimation of CVD, as UCoD in Tonga. This indicates the importance of controlling various modifiable risks for atherosclerotic CVD (including stroke) including hypertension, tobacco use, and saturated fat intake, besides obesity and diabetes. Accurate certification of diabetes as a direct cause of death (Part 1) or contributory factor (Part 2) is needed to ensure that valid UCoD are assigned. Examination of multiple cause-of-death data can improve understanding of the underlying causes of premature mortality to better inform health planning.

Tafuna'i M, Turner RM, Richards R, Sopoaga F, Walker R. The prevalence of chronic kidney disease in Samoans living in Auckland, New Zealand. Nephrology (Carlton) 2022; 27:248-259. [PMID: 34698436 DOI: 10.1111/nep.13990] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2021] [Revised: 10/11/2021] [Accepted: 10/20/2021] [Indexed: 11/27/2022]
Abstract
AIMS Pacific peoples have higher rates of chronic kidney disease (CKD) and are five times more likely to commence kidney replacement therapy compared with New Zealand (NZ) Europeans. As the majority live Auckland, this study looked at the prevalence of CKD in two Auckland Pacific Island health providers caring for a large proportion of Pacific peoples, of which almost 50% are Samoan, as well as NZ Europeans. METHODS De-identified information was requested on individuals who had two or more CKD tests (serum creatinine and urinary albumin creatinine ratios) more than 3 months apart. CKD prevalence across different demographic groups was determined. Logistic regression was used to look at associations of known risk factors and CKD. RESULTS Data from 25 127 patients was evaluated. Of the total sample, 7451 individuals identified as Samoans. The prevalence of CKD amongst all Samoans in this sample was 17.8% increasing to 36.3% in those Samoans that had been tested for CKD. The prevalence of CKD in this total sample was 13% increasing to 27.5% considering only those who had CKD testing. The odds of Samoans having CKD (adjOR: 1.9 [95%CI 1.7, 2.2]), all other Pacific Island ethnicities identified and NZ Maori (adjOR:1.5 [95%CI 1.3, 1.8]), were increased compared with non-Māori-non-Pacific (likelihood p value <.001). CONCLUSION We report the high prevalence of CKD (15.9%-33.4%) in Samoans living in New Zealand. This reveals an urgent need for further studies to develop strategies to prevent or reduce the development of kidney failure and premature death.

Global Health 2021; 17:136. [PMID: 34838081 PMCID: PMC8626938 DOI: 10.1186/s12992-021-00788-z] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/26/2021] [Accepted: 11/16/2021] [Indexed: 11/11/2022] Open
Abstract
Background In Tonga, import duties were lowered on tinned fish and seafood in 2013 and raised on soft drinks, dripping and other animal fats. Additional import duties were applied to soft drinks and dripping and other fats in 2016 and duties were also applied to high fat meats, mutton flaps and turkey tails. The objective of this study was to describe barriers to and facilitators of these import duties from a policy-maker perspective. Methods A case study was conducted to analyse implementation of policies originally modelled by the Pacific Obesity Prevention in Communities project to reduce mortality in the Kingdom of Tonga. Policymakers (n = 15) from the Ministries of Revenue, Health, Finance and Labour and Commerce involved in the development and implementation of Tonga’s food-related policies participated in key-informant interviews. Results The main facilitator of import duties were strong leadership and management, cross-sector collaboration, awareness raising and advocacy, nature of the policy, and the effective use of data to model policy impacts and inform the general public. The absence of clear lines of responsibility and a decline in collaboration over time were identified as barriers to implementation of the import duties. Conclusion In a small Island state implementing import duties to prevent non-communicable disease can be straight forward providing policymakers and the community have a shared understanding of the health and economic costs of NCDs.

Abstract
BACKGROUND Despite the increasing prevalence of Type 2 Diabetes Mellitus (T2DM) in the Kingdom of Tonga, little is known of non-communicable disease experiences among adults living in this location. This investigation aimed to explore the barriers and enablers to healthy lifestyle in a group of men and women living with T2DM residing in this Pacific Island nation. METHODS This qualitative study consisted of three semi-structured focus groups (n = 16), conducted at the only Tongan Public Hospital located at Nuku'alofa, capital of Tonga (north coast of the island of Tongatapu). Discussions were audio-recorded, transcribed, cross-checked for consistency, and entered into a word processing document for analysis. Thematic analysis was employed to synthesise results. RESULTS Four main themes were identified: (1) Knowledge and Support; (2) Fear and Motivation; 3) Physical and Psychological Environment; and (4) Faith and Culture. CONCLUSIONS The qualitative findings from this study will assist the future development and information dissemination of culturally appropriate lifestyle-related for men and women living with T2DM in the Kingdom of Tonga. The need for collaboration between practitioners at the hospital, the church, family members, and local traditional healers is important if the lifestyle-related needs and wants of this group of people are to be met.

Abstract
INTRODUCTION Compared with the number of studies in adults, body weight in relation to tobacco use has been understudied in the adolescent population. This study aimed to examine the association between underweight, overweight and tobacco use in low- and middle-income countries. METHODS Data were derived from the Global School-Based Student Health Survey (GSHS). Data from 71176 adolescents aged 12-15 years residing in 23 countries were analyzed. The Centers for Disease Control and Prevention (CDC) 2000 growth charts were used to identify underweight, normal weight, and overweight/ obesity. Weighted age- and gender-adjusted prevalence of weight categories and tobacco use was calculated. Multivariate logistic regression analysis was performed to estimate the association between weight categories and tobacco use for each country, controlling for covariates. Pooled odds ratios and confidence intervals were computed using random- or fixed-effects meta-analyses. RESULTS A significant association between weight categories and tobacco use was evident in only a few countries. Adolescents reporting tobacco use in French Polynesia, Suriname, and Indonesia, had 72% (95% CI: 0.15-0.56), 55% (95% CI: 0.24-0.84), and 24% (95% CI: 0.61-0.94) lower odds of being underweight, respectively. Adolescents reporting tobacco use in Uganda, Algeria, and Namibia, had 2.30 (95% CI: 1.04-5.09), 1.71 (95% CI: 1.25-2.34), and 1.45 (95% CI: 1.00-2.12) times greater odds of being overweight/obese, but those in Indonesia and Malaysia had 33% (95% CI: 0.50-0.91) and 16% (95% CI: 0.73-0.98) lower odds of being overweight/obese. CONCLUSIONS The association between tobacco use and BMI categories is likely to be different among adolescents versus adults. Associating tobacco use with being thin may be more myth than fact and should be emphasized in tobacco prevention programs targeting adolescents.

Abstract
Kingdom of Tonga in Polynesia is one of the most obese nations where metabolic conditions, sedentary lifestyles, and poor quality diet are widespread. These factors can lead to poor musculoskeletal health. However, whether metabolic abnormalities such as osteoporosis occurred in archaeological populations of Tonga is unknown. We employed a microscopic investigation of femur samples to establish whether bone loss afflicted humans in this Pacific region approximately 3000 years ago. Histology, laser confocal microscopy, and synchrotron Fourier-transform infrared microspectroscopy were used to measure bone vascular canal densities, bone porosity, and carbonate and phosphate content of bone composition in eight samples extracted from adult Talasiu males and females dated to 2650 BP. Compared to males, samples from females had fewer vascular canals, lower carbonate and phosphate content, and higher bone porosity. Although both sexes showed evidence of trabecularised cortical bone, it was more widespread in females (35.5%) than males (15.8%). Our data suggest experiences of advanced bone resorption, possibly as a result of osteoporosis. This provides first evidence for microscopic bone loss in a sample of archaeological humans from a Pacific population widely afflicted by metabolic conditions today.

Abstract
BACKGROUND Tonga is a South Pacific Island country with a population of 100,651 (2016 Census). This study examines Tongan infant mortality rates (IMR), under-five mortality rates (U5MR), adult mortality and life expectancy (LE) at birth from 2010 to 2018 using a recent collation of empirical mortality data over the past decade for comparison with other previously published mortality estimates. METHODS Routinely collected mortality data for 2010-2018 from the Ministry of Health, national (Vaiola) hospital, community nursing reports, and the Civil Registry, were consolidated by deterministic and probabilistic linkage of individual death records. Completeness of empirical mortality reporting was assessed by capture-recapture analysis. The reconciled data were aggregated into triennia to reduce stochastic variation, and used to estimate IMR and U5MR (per 1000 live births), adult mortality (15-59, 15-34, 35-59, and 15-64 years), and LE at birth, employing the hypothetical cohort method (with statistical testing). Mortality trends and differences were assessed by Poisson regression. Mortality findings were compared with published national and international agency estimates. RESULTS Over the three triennia in 2010-2018, levels varied minimally for IMR (12-14) and U5MR (15-19) per 1000 births (both ns, p > 0.05), and also for male LE at birth of 64-65 years, and female LE at birth 69-70 years. Cumulated risks of adult mortality were significantly higher in men than women; period mortality increases in 15-59-year women from 18 to 21% were significant (p < 0.05). Estimated completeness of the reconciled data was > 95%. International agencies reported generally comparable estimates of IMR and U5MR, with varying uncertainty intervals; but they reported significantly lower adult mortality and higher LE than the empirical estimates from this study. CONCLUSIONS Life expectancy in Tonga over 2010-2018 has remained relatively low and static, with low IMR and U5MR, indicating the substantial impact from premature adult mortality. This analysis of empirical data (> 95% complete) indicates lower LE and higher premature adult mortality than previously reported by international agencies using indirect and modelled methods. Continued integration of mortality recording and data systems in Tonga is important for improving the completeness and accuracy of mortality estimation for local health monitoring and planning.

Abstract
The purpose of this study is to determine the factors associated with adverse maternal outcomes in pregnancies complicated by gestational diabetes mellitus (GDM) in urban Fiji. This cross-sectional study used data from existing records of singleton pregnant women with GDM attending the Colonial War Memorial Hospital (CWMH) Suva Fiji between June 2013 and May 2014. Data retrieved included demographic data, antenatal and intrapartum care data, route of delivery, treatment modality, and maternal risk factors. The prevalence of GDM is 3.0%, n = 255/8698, and the most frequent maternal complications were induction of labor (66%), C-section (32%), and preeclampsia (19%), and 25% had babies with birthweight > 4 kg. Older women (≥ 36 years) and those treated with insulin were 5.2 times and 10.7 times, respectively, more likely to have labor induction during childbirth compared with younger women and those on dietary management. Family history of diabetes was associated with 2.4× and/or 2.5× higher odds of cesarean delivery and/or develop hypertension in pregnancy, respectively. Parity > 5 children and diagnoses of GDM after the first trimester reduced the odds of cesarean delivery. The odds of developing preeclampsia in GDM was 3.4 times higher (95% confidence interval (CI) of adjusted odds ratio (aOR): 1.03, 18.78) among obese women than normal-weight women, and married women were less likely to have babies with birthweight > 4 kg. The prevalence of and adverse outcomes among women with GDM attending antenatal public health care in Suva Fiji were higher than previously reported from the hospital. Older and multiparous women with GDM, those insulin treated, and with a strong family history and high body mass index (BMI) need special attention and better monitoring by health care personnel to reduce adverse outcomes during pregnancy.

Abstract
There has been a rapid escalation of type 2 diabetes (T2D) in developing countries, with varied prevalence according to rural vs urban habitat and degree of urbanization. Some ethnic groups (eg, South Asians, other Asians, and Africans), develop diabetes a decade earlier and at a lower body mass index than Whites, have prominent abdominal obesity, and accelerated the conversion from prediabetes to diabetes. The burden of complications, both macro- and microvascular, is substantial, but also varies according to populations. The syndemics of diabetes with HIV or tuberculosis are prevalent in many developing countries and predispose to each other. Screening for diabetes in large populations living in diverse habitats may not be cost-effective, but targeted high-risk screening may have a place. The cost of diagnostic tests and scarcity of health manpower pose substantial hurdles in the diagnosis and monitoring of patients. Efforts for prevention remain rudimentary in most developing countries. The quality of care is largely poor; hence, a substantial number of patients do not achieve treatment goals. This is further amplified by a delay in seeking treatment, "fatalistic attitudes", high cost and non-availability of drugs and insulins. To counter these numerous challenges, a renewed political commitment and mandate for health promotion and disease prevention are urgently needed. Several low-cost innovative approaches have been trialed with encouraging outcomes, including training and deployment of non-medical allied health professionals and the use of mobile phones and telemedicine to deliver simple health messages for the prevention and management of T2D.

Abstract
PURPOSE OF REVIEW Diabetes mellitus prevalence is increasing throughout the world as a consequence of growing rates of obesity, metabolic syndrome, and westernization of lifestyle. It is currently unknown to what extent these trends affect the global burden of diabetic kidney disease (DKD). This review seeks to describe the global burden of DKD and how it has changed throughout time using recently released results of the Global Burden of Disease 2017 Study. RECENT FINDINGS DKD prevalence has remained fairly stable at the global level and among many world regions since 1990. At the global level, the proportion of DKD deaths relative to other types of CKD is increasing. Certain world regions still have very high rates of DKD, whereas other world regions have decreasing prevalence and mortality. Screening will likely play an important role in mitigating the growing burden within high-risk regions.

Abstract
CONTEXT Fiji has undergone an epidemiological transition, characterised by declining infectious disease and childhood mortality, that has been offset by rising cardiovascular disease mortality. Other Pacific Island states are in a comparable situation. OBJECTIVE With a focus on Fiji, this study reviews and contextualises research performed by the authors and others that examines cardiovascular disease (CVD) and type 2 diabetes (T2DM) and their risk factors in Pacific Island states. METHODS This overview covers evidence for the causes and consequences of CVD risk factors and the epidemiological transition and reflects on biological and evolutionary hypotheses. It is based on studies the authors carried out that synthesised disparate population-based CVD risk factor surveys conducted in Fiji over 1980-2012. RESULTS Prevalences of obesity, T2DM and hypertension continue to increase in the Fiji population. Tobacco smoking prevalence has decreased, but remains relatively high in men compared to many developed countries. T2DM and hypertension trends, and CVD consequences related to diet, exercise and tobacco smoking, have placed the Fiji population in a variant of the epidemiological transition manifesting as a plateau in life expectancy similar to that of numerous developed countries during the mid-20th century. CONCLUSION There is evidence that risk factors and consequent CVD mortality can be reduced in populations. Obesity and T2DM reductions have been observed only in populations surviving in dire circumstances. Interventions to lower the prevalence of CVD and T2DM risk factors in the Fiji population require multi-faceted approaches, with continual monitoring and evaluation for their impact on these risk factors and morbidity and mortality outcomes.

Abstract
INTRODUCTION The worldwide prevalence of Gestational Diabetes Mellitus (GDM) is increasing day by day. However, there is a knowledge gap regarding the effect of ethnic and geographical distribution on the risk of developing Diabetes Mellitus (DM) in women with history of GDM. This review was conducted to find out the role of ethnic and geographical distribution on the risk of developing DM is women with GDM. AREAS COVERED In this review we conducted a comprehensive search of published studies through different electronic databases (PubMed, Google Scholar, CINAHL, CINAHL plus and EMBASE) published between 1990 and 2017. The studies which were published in English investigated the risk of development of DM in women with previous history of GDM, reported outcome according to ethnicity with specific criteria of reporting DM and GDM, reported development of diabetes after 6 month of delivery in women with GDM during pregnancy were included. Initially, 350 articles were identified, among which 16 articles were included in the final review. EXPERT COMMENTARY Studies showed the increased risk of developing subsequent DM is associated with precedent GDM. Around 7-84% women developed diabetes after GDM in five years follow up, where some studies reported the risk continues to increase with increasing age. Risk of DM was found higher for some specific ethnicities, irrespective of the location of the study conducted. East Indian women showed the highest risk of postpartum DM after GDM and the crude prevalence remained almost similar in all form of study worldwide. Public health programme should focus more on women belonging to high-risk ethnicity of GDM for the prevention of postpartum DM.

Abstract
AIMS Population surveys of Type 2 diabetes mellitus and obesity conducted in Samoa over three decades have used varying methodologies and definitions. This study standardizes measures, and trends of Type 2 diabetes mellitus and obesity for 1978-2013 are projected to 2020 for adults aged 25-64 years. METHODS Unit records from eight surveys (n = 12 516) were adjusted to the previous census for Division of residence, sex and age to improve national representativeness. Type 2 diabetes mellitus is defined as a fasting plasma glucose ≥ 7.0 mmol/l and/or on medication. Obesity is defined as BMI ≥ 30 kg/m2 . Random effects meta-regression was employed to assess time trends following logit transformation. Poisson regression from strata was used to assess the effects of mean BMI changes on Type 2 diabetes mellitus period trends. RESULTS Over 1978-2013, Type 2 diabetes mellitus prevalence increased from 1.2% to 19.6% in men (2.3% per 5 years), and from 2.2% to 19.5% in women (2.2% per 5 years). Obesity prevalence increased from 27.7% to 53.1% in men (3.6% per 5 years) and from 44.4% to 76.7% (4.5% per 5 years) in women. Type 2 diabetes mellitus and obesity prevalences increased in all age groups. From period trends, Type 2 diabetes mellitus prevalence in 2020 is projected to be 26% in men and women. Projected obesity prevalence is projected to be 59% in men and 81% in women. Type 2 diabetes mellitus period trends attributable to BMI increase are estimated as 31% (men) and 16% (women), after adjusting for age. CONCLUSION This is the first study to produce trends of Type 2 diabetes mellitus and obesity in Samoa based on standardized data from population surveys. Type 2 diabetes mellitus is equally prevalent in both sexes, and obesity is widespread. Type 2 diabetes mellitus prevalence in Samoa is likely to continue to increase in the near future.

Six-year changes in the prevalence of obesity and obesity-related diseases in Northeastern China from 2007 to 2013. Sci Rep 2017; 7:41518. [PMID: 28128316 PMCID: PMC5269745 DOI: 10.1038/srep41518] [Citation(s) in RCA: 20] [Impact Index Per Article: 2.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/07/2016] [Accepted: 12/20/2016] [Indexed: 12/28/2022] Open
Abstract
Obesity and obesity-related diseases are important public health challenges. In this study, we aimed to provide updated trends in the prevalence of these conditions. We conducted two independent cross-sectional surveys of the general population aged 20–75 years in 2007 and 2013 in Jilin, China. A total of 3636 (1719 males) and 1359 (602 males) participants were enrolled in the 2007 and 2013 surveys, respectively. Obesity-related diseases were defined as type 2 diabetes, hypertension, dyslipidemia and non-alcoholic fatty liver disease (NAFLD). The age-standardized prevalence of obesity, overweight, diabetes, pre-diabetes, dyslipidemia and NAFLD increased from 2007 to 2013 from 15.82% to 19.41%, 35.85% to 41.80%, 6.37% to 9.23%, 16.77% to 23.49%., 53.46% to 65.50%, and 23.48% to 44.31% in males, respectively, and from 13.18% to 18.77%, 31.11% to 37.54%, 4.41% to 8.48%, 8.10% to 16.49%, 41.96% to 54.70%, and 17.56% to 43.06% in females, respectively. However, the prevalence of hypertension remained stable (males: 38.10% vs. 38.63% and females: 33.04% vs. 33.01% in 2007 and 2013, respectively). The prevalence of obesity and obesity-related diseases, except for hypertension, increased significantly in the general population in Northeastern China. More targeted measures should be implemented to address the serious challenges presented by these diseases.

Abstract
Comparison of the prevalence of type 2 diabetes mellitus (T2DM) in adults aged 25-64 years in selected Pacific Island countries using whole blood and plasma glucose cut-off points. Unit records of STEPwise approach to Surveillance (STEPS) surveys obtained from Fiji, Samoa, and Tonga Ministries of Health; T2DM prevalence recalculated using whole blood and plasma cut-off points. Shaded bars indicate T2DM prevalence based on correct glucose cut-off points for the glucose meter used (fasting blood glucose [FBG] ≥6.1 mmol/L for early surveys1,3,5 ; fasting plasma glucose [FPG] ≥7.0 mmol/L for later surveys),2,4,6 whereas open bars show T2DM prevalence based on incorrect glucose cut-off points (FPG ≥6.1 mmol/L for later surveys).2,4,6 Highlights Incorrect glucose cut-off points were applied to the Fiji 2011, Samoa 2013, and Tonga 2012 STEPS surveys. This doubled the actual T2DM prevalences compared to using the correct glucose cut-off points. The errors occurred due to modern glucose meters producing measurements in plasma-equivalent concentrations from whole blood samples. The incorrect whole blood glucose cut-off (≥6.1mmol/L) was applied instead of the correct plasma glucose cut-off (≥7.0mmol/L). This error likely affects other Pacific states, and may have global ramifications.
