The effects of yoga in prevention of pregnancy complications in high-risk pregnancies: A randomized controlled trial

Risk factors for gestational diabetes: is prevention possible?

“…Although not all GDM events can be prevented, lifestyle interventions introduced early in pregnancy or before pregnancy have the potential of preventing GDM development, at least among some women. This is supported by the promising findings from large observational studies on pre-pregnancy diet and lifestyle (Table 1), aforementioned positive findings from studies that started the intervention early in pregnancy [31][32][33][34][35][36][37][38][39][40], and by the successful prevention of type 2 diabetes with diet and lifestyle modification among non-pregnant individuals, for example, in the FDPS [26] and in the US DPP [27]. Finally, findings from animal and human medical studies have demonstrated the biological plausibility of improving insulin sensitivity and secretion through diet and lifestyle modification.…”

“…The few studies that did demonstrate a significant beneficial effect of diet and/or physical activity all started the intervention relatively early, in the first trimester, before or near 13 weeks of gestation [31][32][33][34][35][36][37][38][39][40]. For example, among all the published studies to date on physical activity interventions for GDM prevention [41,42], the point estimate for the majority of studies indicate a beneficial effect, yet only those with the intervention starting early in the first trimester had statistically significant findings [33][34][35]38]. The same was true for intervention approaches that combined physical activity with diet modification [36,37,40], administered diet modification/supplement alone [39] or pharmacological intervention with metformin [31].…”

Interventions integrating non-communicable disease prevention and reproductive, maternal, newborn, and child health: A systematic review

“…Subsequently, we evaluated the remaining 19 studies for eligibility by reviewing the full-text articles. Among them, we included two randomized controlled studies (three published articles) and four non-randomized interventions (26)(27)(28)(29)(30)(31)(32), which were all written in English and had been published in peer-reviewed journals, in the final analysis. For randomized controlled trial studies, we initially selected three articles.…”

“…For randomized controlled trial studies, we initially selected three articles. However, we integrated those written by Jayashree et al and Rakhshani et al into the same category (i.e., the Jayashree-Rakhshani study), because both articles involved the same intervention study (27,32). Table 1 shows the risks of bias for the two randomized controlled trial studies.…”

“…All other biases were "low" in the selected studies. However, high attrition bias was observed in the Jayashree-Rakhshani study, because the dropout rate was almost 35% of the randomized participants in the intervention group (27,32). Table 2 shows the risk of bias in the four nonrandomized intervention studies.…”
