Impact of adopting the 2013 World Health Organization criteria for diagnosis of gestational diabetes in a multi-ethnic Asian cohort: a prospective study.

BACKGROUND: We assessed the impact of adopting the 2013 World Health Organization (WHO) diagnostic criteria on the rates of gestational diabetes (GDM), pregnancy outcomes and identification of women at future risk of type 2 diabetes. METHODS: During a period when the 1999 WHO GDM criteria were in effect, pregnant women were universally screened using a one-step 75 g 2-h oral glucose tolerance test at 26-28 weeks' gestation. Women were retrospectively reclassified according to the 2013 criteria, but without the 1-h glycaemia measurement. Pregnancy outcomes and glucose tolerance at 4-5 years post-delivery were compared for women with GDM classified by the 1999 criteria alone, GDM by the 2013 criteria alone, GDM by both criteria and without GDM by both sets of criteria. RESULTS: Of 1092 women, 204 (18.7%) and 142 (13.0%) were diagnosed with GDM by the 1999 and 2013 WHO criteria, respectively, with 27 (2.5%) reclassified to GDM and 89 (8.2%) reclassified to non-GDM when shifting from the 1999 to 2013 criteria. Compared to women without GDM by both criteria, cases reclassified to GDM by the 2013 criteria had an increased risk of neonatal jaundice requiring phototherapy (relative risk (RR) = 2.78, 95% confidence interval (CI) 1.32, 5.86); despite receiving treatment for GDM, cases reclassified to non-GDM by the 2013 criteria had higher risks of prematurity (RR = 2.17, 95% CI 1.12, 4.24), neonatal hypoglycaemia (RR = 3.42, 95% CI 1.04, 11.29), jaundice requiring phototherapy (RR = 1.71, 95% CI 1.04, 2.82), and a higher rate of abnormal glucose tolerance at 4-5 years post-delivery (RR = 3.39, 95% CI 2.30, 5.00). CONCLUSIONS: Adoption of the 2013 WHO criteria, without the 1-h glycaemia measurement, reduced the GDM rate. Lowering the fasting glucose threshold identified women who might benefit from treatment, but raising the 2-h threshold may fail to identify women at increased risk of adverse pregnancy and future metabolic outcomes. TRIAL REGISTRATION: NCT01174875 . Registered 1 July 2010 (retrospectively registered).

Association between pre-pregnancy consumption of meat, iron intake, and the risk of gestational diabetes: the SUN project.

PURPOSE: We assessed the association of total meat, processed, and unprocessed red meat and iron intake with the risk of developing gestational diabetes mellitus (GDM) in pregnant women. METHODS: We conducted a prospective study among 3298 disease-free Spanish women participants of the SUN cohort who reported at least one pregnancy between December 1999 and March 2012. Meat consumption and iron intake were assessed at baseline through a validated, 136-item semi-quantitative, food frequency questionnaire. We categorized total, red, and processed meat consumption and iron intake into quartiles. Logistic regression models were used to adjust for potential confounders. RESULTS: We identified 172 incident cases of GDM. In the fully adjusted analysis, total meat consumption was significantly associated with a higher risk of GDM [OR = 1.67 (95% CI 1.06-2.63, p-trend 0.010)] for the highest versus the lowest quartile of consumption. The observed associations were particularly strong for red meat consumption [OR = 2.37 (95% CI 1.49-3.78, p-trend < 0.001)] and processed meat consumption [OR = 2.01 (95% CI 1.26-3.21, p-trend 0.003)]. Heme iron intake was also directly associated with GDM [OR = 2.21 (95% CI 1.37-3.58, p-trend 0.003)], although the association was attenuated and lost its statistical significance when we adjusted for red meat consumption [OR = 1.57 (95% CI 0.91-2.70, p-trend 0.213)]. No association was observed for non-heme and total iron intake, including supplements. CONCLUSIONS: Our overall findings suggest that higher pre-pregnancy consumption of total meat, especially red and processed meat, and heme iron intake, are significantly associated with an increased GDM risk in a Mediterranean cohort of university graduates.

Leveraging EHRs for patient engagement: perspectives on tailored program outreach.

OBJECTIVES: Electronic health records (EHRs) present healthcare delivery systems with scalable, cost-effective opportunities to promote lifestyle programs among patients at high risk for type 2 diabetes, yet little consensus exists on strategies to enhance patient engagement. We explored patient perspectives on program outreach messages containing content tailored to EHR-derived diabetes risk factors-a theory-driven strategy to increase the persuasiveness of health communications. STUDY DESIGN: Convergent mixed methods. METHODS: Within an integrated healthcare delivery system, women with a history of gestational diabetes participated in 1 of 6 ethnic-specific focus groups to elicit diverse perspectives and a survey yielding quantitative data to contextualize qualitative responses. RESULTS: The sample included 35 participants (80% racial/ethnic minorities; mean age = 36 years). Themes regarding tailored messages centered on diabetes risk communication (opposing attitudes about whether to feature diabetes risk factors), privacy (how and whether patient data should be accessed), authenticity (perceiving messages as personalized vs generically computer generated), and preferences for messages sent by one's personal physician. Trust in the medical profession and perceived risk for diabetes were similar to levels reported in comparable samples. CONCLUSIONS: Patient reactions highlight the challenges of leveraging EHRs for tailored messages. Some viewed messages as caring reminders to take preventive action and others raised concerns over intrusiveness. Optimal lifestyle program outreach to improve quality of care for women at high risk for diabetes may require communication from personal physicians, careful development to mitigate concerns over privacy and authenticity, and techniques to counteract the threatening nature of personalized risk communication.

Attitudes towards gestational diabetes among a multiethnic cohort in Australia.

AIMS: This study aimed to examine the attitudes and beliefs towards gestational diabetes of a multiethnic sample of pregnant women with gestational diabetes. BACKGROUND: Women from non-Caucasian background are disproportionately represented in gestational diabetes statistics. This is of particular importance in multicultural Australia, where increasing numbers of non-Caucasian women give birth. DESIGN: Cross-sectional survey. METHODS: The Diabetes Attitude Scale, version 3 was administered to 200 women with gestational diabetes from Vietnamese, Indian, Filipino and Caucasian backgrounds. RESULTS: A total of 143 questionnaires were returned indicating a response rate of 71·5%. There were significant between group differences in terms of educational level (p = 0·001) and English fluency (p = 0·001). Lower educational level, though not English language fluency, was associated with poorer appreciation of gestational diabetes as a serious condition and also with a lower valuing of tight glucose control. This effect was seen irrespective of ethnic group. Indian and Vietnamese women indicated a lower valuing of patient autonomy and also reported less negative psychological effects than Caucasian and Filipino women. CONCLUSIONS: Women from non-Caucasian ethnicities may be at risk of poorer self-management of gestational diabetes related to lower education, lower health literacy and a lower appreciation of gestational diabetes as a serious condition. RELEVANCE TO CLINICAL PRACTICE: Nurses and midwives provide information and advice to women with gestational diabetes. Knowledge about factors that impact on attitude towards gestational diabetes among multiethnic populations is important for developing educational programmes to address their needs.

Beliefs, barriers, social support, and environmental influences related to diabetes risk behaviours among women with a history of gestational diabetes.

ISSUE ADDRESSED: Women with previous gestational diabetes mellitus (GDM) are at increased risk of developing type 2 diabetes; this risk is higher in non-Caucasian women. This study explored the beliefs, attitudes, social support, environmental influences and other factors related to diabetes risk behaviours among Arabic, Cantonese/Mandarin, and English speaking women with recent GDM. METHODS: Women living in the Sydney metropolitan area (Australia) who had GDM 6-36 months previously were included. In-depth semi-structured telephone interviews on women's experiences and perceptions of GDM and the lifestyle risk factors for developing type 2 diabetes were conducted in the language participants spoke at home (n=20 Arabic, 20 Cantonese/Mandarin, 17 English). Data were analysed for underlying themes using NVivo software. RESULTS: Mental distress, role perceptions, social support and cultural expectations were major issues related to women's struggles to find the right balance between the large proportion of household and child care responsibilities and leading a healthy lifestyle. CONCLUSION: Women's ability to follow a healthy lifestyle is embedded in their psychological wellbeing and the social and cultural context of their lives. The study highlights the need for a holistic approach that ensures personal support and access to services as well as lifestyle specific programs.

Does the presence of polycystic ovary syndrome increase the risk of obstetrical complications in women with gestational diabetes?

OBJECTIVE: To determine whether women with both polycystic ovary syndrome (PCOS) and gestational diabetes mellitus (GDM) have an increased risk of obstetric complications compared with women with GDM alone. METHODS: A retrospective cohort study of maternal/fetal outcomes in women with GDM and PCOS was compared with women with GDM alone. Outcomes were compared using Fisher's exact test for categorical variables and t-test for continuous variables. Logistic regression models allowed for the calculation of odds ratios and 95% confidence intervals (CIs) for each outcome, adjusted for confounding. RESULTS: One hundred seventy one women were included in the study. Significantly more women with both GDM and PCOS had pregnancy-induced hypertension/preeclampsia (15.9% vs. 3.9%, p = 0.019, OR = 4.62, 95% CI = 1.38-15.41). Multiple logistic regression revealed that this increase persisted after controlling for body mass index (p = 0.028, OR = 4.43, 95% CI = 1.17-16.72) and parity (p = 0.050, OR = 3.45, 95% CI = 1.00-11.92). Women with GDM and PCOS tended to have more preterm deliveries (25.0% vs. 11.8%, p = 0.063). More infants of women with GDM and PCOS required phototherapy treatment for hyperbilirubinemia (25.0% vs. 7.9%, p = 0.0066, OR = 3.90, 95% CI = 1.52-9.98). Logistic regression revealed that this association persisted after controlling for preterm delivery (OR = 3.18, 95% CI = 1.14-8.82, p = 0.026). CONCLUSIONS: Mothers with both disorders should be monitored more carefully and counseled regarding their increased risk of both maternal and fetal complications.

Management of gestational diabetes from the patient's perspective--a comparison of Swedish and Middle-Eastern born women.

AIM: To explore patients' evaluation of a specialized diabetes clinic for management of women with gestational diabetes born in Sweden and the Middle East and its contribution to a decreased level of stress and improved coping capability to promote health in patients receiving care. BACKGROUND: No studies comparing patients' perceptions of healthcare in women of different origin with gestational diabetes have been found. A perceived clinical problem in specialized diabetes care is of lower activity level in self-care in foreign- than Swedish-born women and the question is whether the healthcare organization is optimal in meeting different individuals' needs. DESIGN: Explorative study. METHOD: Semi-structured individual interviews by external evaluators. PARTICIPANTS: Consecutive sample. Females with gestational diabetes, 13 born in Sweden and 14 born in the Middle East. RESULTS: The healthcare model was perceived as functioning well. Swedish women were problem focused and information seeking. Frustration and stress were increased due to perceived delay in information concerning gestational diabetes, limited access to telephone service and lack of confidence in staff because they lacked the expected competence. Control of gestational diabetes and pregnancy by different persons led to perceived lack of holistic care. Women from the Middle East felt cared, had been given the necessary information and claimed to follow advice. Adequate information reduced respondents' anxiety and increased their control over the situation. CONCLUSIONS: The clinic needs to be further improved by adapting programmes to persons to become problem focused by giving adequate information immediately. RELEVANCE TO CLINICAL PRACTICE: Cultural differences in coping strategies and attitudes to gestational diabetes need to be considered. Training of staff working with gestational diabetes patients is urgently needed.

Swedish and Middle-Eastern-born women's beliefs about gestational diabetes.

OBJECTIVE: to compare beliefs about health and illness between women born in Sweden and the Middle East who developed gestational diabetes (GD). DESIGN: a qualitative, explorative study using semi-structured interviews. SETTING: in-hospital diabetes specialist clinic in Sweden. PARTICIPANTS: consecutive sample of women with GD; 13 born in Sweden and 14 born in the Middle East. MEASUREMENT AND FINDINGS: all the women described health as freedom from disease, and expressed worries for the baby's health and well-being. Women from the Middle East did not know the cause of GD, discussed the influence of social factors, such as being an immigrant, and supernatural factors, tried to adapt to the disease and thought it would disappear after birth, felt they had more pregnancy-related complications but had not received any treatment. Swedish women attributed GD to inheritance, environment and hormonal change, feared developing Type 2 diabetes, found work-related stress harmful to their health, more often sought help, used medications against pregnancy-related complications, and were more often on sick-leave from work. KEY CONCLUSIONS: Swedish women initiated a battle against GD, demanded medical treatment for pregnancy-related complications because of gainful employment and viewed pregnancy as a disease. Women from the Middle East temporarily adapted to the disease and perceived pregnancy and related problems as a natural part of life. IMPLICATIONS FOR PRACTICE: it is important to assess individual beliefs, risk awareness and to meet individual needs for information.
