“…It was encouraging to see a high level of interest and enthusiasm for making positive changes however such a high proportion of adolescents indicating avoiding foods which are potentially valuable sources of vitamins and minerals, such as B vitamins and iron (red meat and eggs) or vitamin D and calcium (oily fish and soft cheese) [17] are of concern. Attention to adequate nutrition in supplying sufficient amount of nutrients are increasingly realised due to its impact on healthy pregnancy and birth outcomes [18].…”

Background: Nutrition is a modifiable factor affecting birth outcomes, particularly in adolescent pregnancies. This study explores diet and supplementation practices, information and advice before, during and after pregnancy from the perspectives of pregnant or new young mothers and healthcare professionals. Methods: Two cross-sectional surveys used online questionnaires for young women who were currently pregnant or who had recently given birth, and health care professionals providing antenatal care. The surveys utilised a combination of question types including free text and multiple choice. Recruitment was conducted via the Tommy's website, online forums for young mothers and professional networks. Results: A total of 205 young women and 146 health care professionals were included in the study. Most young women reported taking supplements at some stage of pregnancy (93.2%), with 54.6% taking it on a daily basis. Those who reported taking supplements less than 7 days a week stated it was mainly due to forgetting. Health care professionals however reported that some young women had difficulties accessing healthy start supplements. Young women reported positive dietary changes; however a significant proportion of participants indicated that they avoided some foods unnecessarily. Avoiding or reducing foods such as red meat (22.7%), eggs (40.6%), oily fish (60.4%) and soft cheese (36.2%) is of concern. Midwife/family nurse (38.0%) was young women's current favourite information source; smartphone applications (apps) and recipe booklets were suggested by over 50% of participants as a new addition to existing services. Health care professionals reported they included nutritional information and support as part of their role; however they felt there were some gaps in knowledge and confidence. Midwives in particular suggested a lack of sufficient time and resources as a main challenge in providing adequate support.

“…6,7 In some developed countries, over-Between 20 and 30 percent of pregnant women suffer from at least one kind of vitamin deficiency. 8 Malnourished women more likely to experience adverse pregnancy outcomes, such as growth-restricted babies, neural tube defects, pre-eclampsia and LBW, which can be prevented through good nutrition and the use of mineral and vitamin supplements. 9 Multivitamin use during pregnancy is a key factor in the prophylaxis and management of nutritional deficiencies, although there are concerns related to excessive vitamin and iron consumption as a general vitamin and/or iron prophylaxis among pregnant women.…”

Background: The aim of this study is to examine whether there is any positive impact of prenatal iron and vitamin supplementation on birth weight, and if this practice could be a cause of macrosomia.Methods: A total of 1,838 term pregnant women were included in this study and were divided into four groups: iron group (women having only iron supplementation), vitamin (women using only multivitamins), vitamin+iron (women using both iron and multivitamin preparations), and control group (women having neither iron nor vitamin supplements). Statistical analysis was performed to compare age, gravida, parity, hemoglobin, BMI and birth weight. Groups were compared in terms of macrosomia and correlation analysis carried out between demographics and birth weight.Results: The birth weight was significantly higher in the vitamin group and the vitamin+iron group than in the iron group and the control group. Vitamin supplementation increased the risk of macrosomia 3.9 times, while vitamin+iron usage increased the risk 4.8 times.Conclusions: Uncontrolled use of multivitamins and/or iron supplements may increase tendency for fetal macrosomia. The use of multivitamins and/or iron supplements by pregnant women must take into account maternal age, maternal diet and maternal BMI. Our findings support a reduction in the unnecessary use of vitamin and iron supplements in pregnancy, and a reversal of the trend to start vitamin and iron supplementation without any control. The increasing prevalence of obesity and excessive weight in pregnant women should be a warning against the uncontrolled usage of vitamins and iron during pregnancy.

“…Yet, these studies usually review non-homogeneous and poorly defined populations which are not stratified in terms of demographic, social, and clinical characteristics. Moreover, accurate assessment of food intake and correct determination of individual food components is difficult and unreliable in non-interventional dietary studies [10,19,20]. The second challenge is that isolated deficiencies of dietary components are rarely encountered.…”

“…Folic acid is available in different doses in multivitamin tablets or in tablets only containing folic acid [9]. It has been reported that folic acid absorption rate is 100% from multivitamin supplements [10]. The present study aimed to determine the serum folate concentrations of Turkish women in the first trimester of pregnancy in respect to the utilization of vitamin supplements.…”
