TARGET:
A systematic review of randomized controlled trials, a comparative analysis of the effect of variousmicronutrients on iron and folic acid on pregnancy in Europe.
METHODS:
Medline and embase were searched. The results were spring at birth, low birth weight, small size forgestational age, perinatal mortality and neonatal mortality. The combined relative risk (op) was estimated using a random effects model. Sources that were studied within the subgroup of Meta-analysis and Meta-regression.
CONCLUSIONS:
Several micronutrients are more effective than iron and folic acid (RR: 0.86, 95% confidence interval, di: 0.79-0.93) and small size for gestational age (RR: 0.85, 95% Di 0.78-0.93). Micronutrient supplements do not have a general effect on perinatal mortality (RR: 1.05, 95% di 0.90-1.22), although a significant heterogeneity was evident (I (2) = 58%, p for heterogeneity = 0.008). The subgroup and meta-regression analysis suggested that dietary supplements were associated with a lower risk of perinatal mortality in the process, including> 50% of mothers had formal education (RR: 0.93, 95% di: 0.82-1.06 ) Or taking medications was started after the means of 20 weeks of gestation (RR: 0.88; 95% di: 0.80-0.97).
CONCLUSION:
Education of mothers or gestational age at the time of admission, possibly capable of observing the heterogeneous consequences of perinatal mortality. Safety, efficacy and effective delivery of maternal micronutrient supplementation requires further research
