“…We have no clear explanation for the two different patterns of FAS use observed between areas, although it could be related, in part, to the different policy statements of regional scientific societies about FAS use, as has been observed for other nutrients such as iodine supplementation. 35 …”

Use of high doses of folic acid supplements in pregnant women in Spain: an INMA cohort study

et al. 2015

ObjectivesWe examined the use of low (<400 μg/day, including no use) and high folic acid supplement (FAS) dosages (≥1000 μg/day) among pregnant women in Spain, and explored factors associated with the use of these non-recommended dosages.DesignPopulation-based cohort study.SettingSpain.ParticipantsWe analysed data from 2332 pregnant women of the INMA study, a prospective mother-child cohort study in Spain.Main outcome measuresWe assessed usual dietary folate and the use of FAS from preconception to the 3rd month (first period) and from the 4th to the 7th month (second period), using a validated food frequency questionnaire. We used multinomial logistic regression to estimate relative risk ratios (RRRs).ResultsOver a half of the women used low dosages of FAS in the first and second period while 29% and 17% took high dosages of FAS, respectively. In the first period, tobacco smoking (RRR=1.63), alcohol intake (RRR=1.40), multiparous (RRR=1.44), unplanned pregnancy (RRR=4.20) and previous spontaneous abortion (RRR=0.58, lower use of high FAS dosages among those with previous abortions) were significantly associated with low FAS dosages. Alcohol consumption (RRR=1.42), unplanned pregnancy (RRR=2.66) and previous spontaneous abortion (RRR=0.68) were associated with high dosage use. In the second period, only tobacco smoking was significantly associated with high FAS dosage use (RRR=0.67).ConclusionsA high proportion of pregnant women did not reach the recommended dosages of FAS in periconception and a considerable proportion also used FAS dosages ≥1000 μg/day. Action should be planned by the Health Care System and health professionals to improve the appropriate periconceptional use of FAS, taking into consideration the associated factors.

“…Routine supplementation of iodine during pregnancy is widely recommended [ 63 ]. Studies conducted in Spain confirm that most women are iodine deficient during pregnancy and lactation and recommend iodine supplements in these stages, even also in preconception [ 64 ].…”

Dietary and Health Profiles of Spanish Women in Preconception, Pregnancy and Lactation

et al. 2014

The nutritional status and lifestyle of women in preconception, pregnancy and lactation determine maternal, fetal and child health. The aim of this cross-sectional study was to evaluate dietary patterns and lifestyles according the perinatal physiological status in a large sample of Spanish women. Community pharmacists that were previously trained to collect the data recruited 13,845 women. General information, anthropometric measurements, physical activity, unhealthy habits and dietary data were assessed using a validated questionnaire. Mean values and percentages were used as descriptive statistics. The t-test, ANOVA or chi-squared test were used to compare groups. A score that included dietary and behavioral characteristics was generated to compare lifestyles in the three physiological situations. The analysis revealed that diet quality should be improved in the three stages, but in a different manner. While women seeking a pregnancy only met dairy recommendations, those who were pregnant only fulfilled fresh fruits servings and lactating women only covered protein group requirements. In all cases, the consumption allowances of sausages, buns and pastries were exceeded. Food patterns and unhealthy behaviors of Spanish women in preconception, pregnancy and lactation should be improved, particularly in preconception. This information might be useful in order to implement educational programs for each population group.

“…This may correspond to the fetal development phase, which happens between the first and second trimesters of pregnancy. Therefore, the children of iodine-deficient mothers are at a higher risk of diminished cognition [ 20 ]. Thus, ensuring optimal and adequate iodine intake from the moment a woman plans to become pregnant is particularly important for preventing adverse effects in their offspring, because even slightly low maternal thyroid hormone levels during pregnancy can cause cognitive delays in their offspring [ 21 ].…”

Iodine Status in Filipino Women of Childbearing Age

et al. 2018

BackgroundIodine deficiency (ID) has become a concern not only among pregnant women, but in women of childbearing age as well. In fact, a recent report suggested that women with moderate to severe ID may experience a significantly longer time to conceive. This study aimed to investigate iodine status in Filipino women of childbearing age.MethodsThe iodine status of 6,194 Filipino women aged 15 to 45 years old was assessed through urinary iodine analysis. A casual spot urine sample was collected from women in households participating in the eighth National Nutrition Survey conducted by the Food and Nutrition Research Institute. The sample was analyzed using ammonium persulfate digestion followed by the Sandell-Kolthoff colorimetric reaction. A median urinary iodine concentration (UIC) of less than 100 µg/L was used to define ID.ResultsThe median UIC was 123 µg/L, indicative of adequate iodine nutrition; however, 21.5% of participants had a UIC below 50 µg/L. The median UIC of women who lived in urban areas (142 µg/L), belonged to the middle to richest class (>124 µg/L), had reached a college education (136 µg/L), and used iodized salt (15 ppm and above; 148 to 179 µg/L) reflected adequate iodine nutrition. ID was found to have been eliminated in the regions of Central Luzon, Eastern Visayas, Calabarzon, Mimaropa, and the National Capital, while mild ID was identified in Western Visayas, Southern and Western Mindanao, and in the Autonomous Region in Muslim Mindanao.ConclusionPockets of ID among women of childbearing age exist in the Philippines. Proper information through education and the use of adequately iodized salt are key measures for improving the iodine status of the studied population.
