Introduction: This scoping review examined the number, types and characteristics of journal publications on ageing in Singapore from 2008 to 2018 to determine how ageing research in medical and social domains in Singapore has transformed over time., Methods: Using relevant search terms, articles were extracted from multiple databases and then screened and reviewed for eligibility and inclusion by independent reviewers. Data such as article title, authors, year of publication, name of journal, type of journal, study design and the kind of data used were charted from the included articles for evidence synthesis., Results: Since 2008, there has been a steady increase in the number of publications on ageing in medical and social domains in Singapore. In the medical domain, publications on Ophthalmology (22%) made up the largest proportion of the existing medical literature on ageing in Singapore, followed by Physical Functioning (17%), which involved physiological measurements of physical well-being, and Geriatrics (16%). Non-medical publications comprised 38% of all the included publications, with publications on the social aspects of ageing (43%) forming the largest group in this cluster, followed by publications on Prevention (19%) and Healthcare services (18%). The study design was mostly observational (82%), with only 3% of interventional studies., Conclusion: While ageing research had expanded in Singapore in the last decade, it was predominantly discipline specific and observational in design. As ageing issues are complex, with biology intersecting with psychology and sociology, we call for greater interdisciplinary collaboration, the conduct of more interventional studies, as well as more research in understudied and emerging areas., (Copyright © 2024 Copyright: © 2024 Singapore Medical Journal.)

Aim: To assess and explore the factors affecting willingness to undergo an early postpartum oral glucose tolerance test (OGTT) and receive postpartum lifestyle modification assistance., Methods: An explanatory sequential mixed-method design was used. A prenatal cross-sectional survey questionnaire (n = 216) was given to women diagnosed with GDM in a tertiary health institution in Singapore and followed up with postpartum semi-structured interviews (n = 30). Multivariate logistic regression and thematic analysis were conducted before merging the findings., Results: Despite universal GDM education, fewer than 75% intended to take the OGTT postpartum, and only 63% felt it was very important. The plan to take the OGTT postpartum was positively associated with a prenatal care provider's specific recommendation. In contrast, Malay women were less likely to take the test. Most women interpreted a care provider's recommendation as implying standard practice, which encouraged intended and actual compliance with testing after giving birth. The perception of moderate to high T2DM risk in the following decade, and subsidized prenatal care, and plan to take the OGTT postpartum were positively associated with willingness to receive postpartum lifestyle behavior support. A mobile application was the preferred method to receive support., Conclusions: In the early postpartum period, women with a history of GDM were willing to receive measures to reduce T2DM risk, primarily if it was under the supervision and recommendation of a care provider. A carefully designed but simple postpartum lifestyle intervention incorporating these preferences that can be integrated into mainstream diabetes prevention programs is warranted., Competing Interests: Declaration of conflicting interests:The author(s) declared the following potential conflicts of interest with respect to the research, authorship, and/or publication of this article: Dr. Cladia Chi has received research funding from the Jana Care project for the work related to the subject matters discussed in this manuscript., (© The Author(s) 2021.)

(1) Background: Breastfeeding has been shown to support glucose homeostasis in women after a pregnancy complicated by gestational diabetes mellitus (GDM) and is potentially effective at reducing long-term diabetes risk. (2) Methods: Data from the Growing Up in Singapore Towards healthy Outcomes (GUSTO) study were analyzed to understand the influence of breastfeeding duration on long-term dysglycemia (prediabetes and diabetes) risk in women who had GDM in the index pregnancy. GDM and dysglycemia four to seven years postpartum were determined by the oral glucose tolerance test (OGTT). A Poisson regression model with a robust error variance was used to estimate incidence rate ratios (IRRs) for dysglycemia four to seven years post-delivery according to groupings of the duration of any breastfeeding (<1, ≥1 to <6, and ≥6 months). (3) Results: Women who had GDM during the index pregnancy and complete breastfeeding information and OGTT four to seven years postpartum were included in this study ( n = 116). Fifty-one women (44%) had postpartum dysglycemia. Unadjusted IRRs showed an inverse association between dysglycemia risk and ≥1 month to <6 months (IRR 0.91; 95% confidence interval [CI] 0.57, 1.43; p = 0.68) and ≥6 months (IRR 0.50; 95% CI 0.27, 0.91; p = 0.02) breastfeeding compared to <1 month of any breastfeeding. After adjusting for key confounders, the IRR for the ≥6 months group remained significant (IRR 0.42; 95% CI 0.22, 0.80; p = 0.008). (4) Conclusions: Our results suggest that any breastfeeding of six months or longer may reduce long-term dysglycemia risk in women with a history of GDM in an Asian setting. Breastfeeding has benefits for mothers beyond weight loss, particularly for those with GDM.

Objective: Lifestyle interventions have been shown to be both effective and cost-effective in reducing diabetes and metabolic risk in high-risk populations. We systematically reviewed the effectiveness and cost-effectiveness of lifestyle interventions on anthropometric, glycemic and cardiovascular outcomes in women with previous gestational diabetes mellitus (GDM)., Method: Relevant randomized control trials (RCT) were identified by searching multiple electronic databases through 20th June 2018. Data were pooled using random-effects models. The review protocol was registered on the PROSPERO international prospective register of systematic reviews (PROSPERO 2016: CRD42018108870)., Results: Twenty-one studies met the inclusion criteria and 16 studies with outcome data were analyzed in the meta-analysis. No RCT studies included cost-effectiveness data on lifestyle interventions. The pooled estimate for postpartum weight showed a significant mean reduction in the intervention arm (-1.8 kg [95% CI: -2.9, -0.6; p = 0.002; I 2  = 92.2%; p < 0.05]). Further, the effect of lifestyle intervention on weight change was significantly greater in studies of longer duration. Most of the other endpoints had modest improvements but only anthropometric endpoints were statistically significant. However, there was high heterogeneity between the studies., Conclusions: Lifestyle interventions showed statistically and clinically significant improvements in anthropometric outcomes. However, more research is needed to explore lifestyle effects on glycemic and cardiovascular risk factors and to establish cost-effectiveness. Methodologically sound, large scale studies on diverse ethnicities and with longer follow-up would establish the real effect of lifestyle interventions to reduce diabetes risk in women with previous GDM., Competing Interests: Declaration of Competing Interest There is no conflict of interest., (Copyright © 2019 European Society for Clinical Nutrition and Metabolism.

IN BRIEF Gestational diabetes mellitus (GDM) increases the risk for type 2 diabetes. This qualitative study aimed to evaluate health care providers' perceptions of care responsibilities and resources related to reducing type 2 diabetes risk among women with previous GDM in Singapore. Health care providers acknowledged a shared responsibility. They felt that they had less understanding of compliance with long-term maintenance of lifestyle change, exacerbated further by fragmentation of follow-up care. The application of more integrated patient-centered care models, combined with greater health literacy, is urgently required in this area.
