  ABSTRACT: AIMS: To systematically review trends in diabetes mellitus (DM) prevalence in adults in China over the last 10 years and to identify the determinants of these trends. METHODS: A systematic search was conducted for studies published between 2000 and 2010. Studies reporting DM prevalence were included if they met the pre-determined criteria. The prevalence estimates and reported determinants of these studies were compared. RESULTS: Twenty-five manuscripts, reporting on 22 studies, were selected for inclusion in the review. There has been an increase in DM prevalence from 2.6% to 9.7% in China over the past decade. DM prevalence is strongly associated with age and is higher in urban residents compared with rural populations. Some studies found a difference in DM prevalence between males and females, but this finding was not consistent. Other commonly reported associations with DM included family history, obesity and hypertension. CONCLUSION: Over the period of 2000-2010, we identify a significant increase in DM prevalence at the national level. It is important for all levels of government to develop more effective strategies to prevent and manage this rising diabetes epidemic. There is also an important need for more large-scale studies of diabetes in the western and central regions of China.

  ABSTRACT: Diabetes in pregnancy, which includes gestational diabetes mellitus (GDM) and type 2 diabetes mellitus (T2DM), is associated with poor outcomes for both mother and infant during pregnancy, at birth and in the longer term. Recent international guidelines recommend changes to the current GDM screening criteria. While some controversy remains, there appears to be consensus that women at high risk of T2DM, including indigenous women, should be offered screening for GDM early in pregnancy, rather than waiting until 24-28 weeks as is current practice. A range of criteria should be considered before changing screening practice in a population sub-group, including: prevalence, current practice, acceptability and whether adequate treatment pathways and follow-up systems are available. There are also specific issues related to screening in pregnancy and indigenous populations. The evidence that these criteria are met for indigenous populations is yet to be reported. A range of study designs can be considered to generate relevant evidence for these issues, including epidemiological, observational, qualitative, and intervention studies, which are not usually included within a single systematic review. The aim of this paper is to describe the methods we used to systematically review studies of different designs and present the evidence in a pragmatic format for policy discussion. The inclusion criteria will be broad to ensure inclusion of the critical perspectives of indigenous women. Abstracts of the search results will be reviewed by two persons; the full texts of all potentially eligible papers will be reviewed by one person, and 10% will be checked by a second person for validation. Data extraction will be standardised, using existing tools to identify risks for bias in intervention, measurement, qualitative studies and reviews; and adapting criteria for appraising risk for bias in descriptive studies. External validity (generalisability) will also be appraised. The main findings will be synthesised according to the criteria for population-based screening and summarised in an adapted "GRADE" tool. This will be the first systematic review of all the published literature on diabetes in pregnancy among indigenous women. The method provides a pragmatic approach for synthesizing relevant evidence from a range of study designs to inform the current policy discussion.
