Efficacy of vitamin D supplementation in gestational diabetes mellitus: Systematic review and meta-analysis of randomized trials.

BACKGROUND: Trials have examined on the benefits of vitamin D supplementation in pregnant women. OBJECTIVE: This review aimed to evaluate whether oral vitamin D supplements, when given to pregnant women with gestational diabetes mellitus (GDM), would improve maternal and neonatal outcomes, compared with no treatment or placebo. METHOD: We performed a systematic review following Cochrane methodology, and randomized trials were included where pregnant women with GDM received vitamin D supplementation versus placebo/no treatment or vitamin D and calcium versus placebo/no treatment. Primary outcomes were preeclampsia, preterm birth, cesarean delivery, gestational hypertension, and adverse events related to vitamin D supplementation. The search strategies were applied to the following databases: MEDLINE, Embase, LILACS, and CENTRAL. Similar outcomes in at least two trials were plotted using Review Manager 5.3 software. The quality of evidence was generated according to the Grading of Recommendations Assessment, Development, and Evaluation (GRADE). RESULTS: The total of 1224 references were identified, eleven trials were potentially eligible, and six were included in this review (totaling 456 women). The meta-analysis of frequency of cesarean deliveries did not show significant differences between groups, none of the trials evaluated the remaining primary outcomes. For secondary outcomes, our results suggest that vitamin D supplementation in pregnant women with GDM may reduce newborn complications such as hyperbilirubinemia, polyhydramnios (RR: 0.40, 95% CI: 0.23 to 0.68; RR: 0.17, 95% CI: 0.03 to 0.89; respectively), and the need for maternal or infant hospitalization (RR: 0.13; 95% CI: 0.02 to 0.98; RR: 0.40, 95% CI: 0.23 to 0.69). However, the evidence was of low or very low quality. CONCLUSION: We did not find moderate or high quality evidence indicating that vitamin D supplementation, when compared with placebo, improves glucose metabolism, adverse maternal and neonatal outcomes related to GDM in pregnant women.

A aceitação da medicina alternativa complementar por gestantes com diabetes / Acceptance of additional alternative medicine by pregnant diabetics

Objetivo: avaliar como as mulheres grávidas com diabetes compreendem e aceitam o uso de práticas integrativas e complementares na saúde, especialmente o Reiki, durante o atendimento pré-natal. Método: trata-se de um estudo qualitativo, descritivo, exploratório, de gestantes diabéticas atendidas num Centro de Investigação do Diabetes Perinatal em um centro terciário, por meio de entrevistas semiestruturadas com 12 gestantes. Audiogravaram-se e transcreveram-se as entrevistas para posterior análise cujos dados foram submetidos à técnica de Análise de Conteúdo. Resultados: demonstrou-se, pela maioria das mulheres gestantes diagnosticadas com diabetes, o conhecimento de algumas práticas integrativas e complementares na saúde. Receber-se-iam, além disso, por um grande número de entrevistadas, tais terapias se essas fossem disponíveis no Sistema Único de Saúde (SUS), porém, a terapia Reiki mostrou ser desconhecida entre as pacientes. Conclusão: serve-se este estudo como ponto de partida para profissionais de saúde introduzirem as terapias integrativas e complementares na saúde pública brasileira. Tornam-se necessários estudos adicionais em outras populações para obter uma visão mais profunda e detalhada do perfil das pacientes em diferentes regiões.(AU)

Objective: to evaluate how pregnant women with diabetes understand and accept the use of integrative and complementary health practices, especially Reiki, during prenatal care. Method: this is a qualitative, descriptive, exploratory study of diabetic pregnant women seen at a Perinatal Diabetes Research Center in a tertiary center, through semi-structured interviews with 12 pregnant women. The interviews were audio recorded and transcribed for later analysis whose data were submitted to the Content Analysis technique. Results: it was demonstrated, by most pregnant women diagnosed with diabetes, the knowledge of some integrative and complementary practices in health. In addition, a large number of respondents would receive such therapies if they were available in the Unified Health System (UHS), but Reiki therapy was unknown to patients. Conclusion: this study serves as a starting point for health professionals to introduce integrative and complementary therapies in Brazilian public health. Further studies in other populations are needed to gain a deeper and more detailed view of patients' profiles in different regions.(AU)

Se necesitan más estudios en otras poblaciones para obtener una visión más profunda y detallada de los perfiles de los pacientes en diferentes regiones.(AU)
