Forsby M, Winkvist A, Bärebring L, Augustin H. Supplement use in relation to dietary intake in pregnancy: an analysis of the Swedish GraviD cohort. Br J Nutr 2024; 131:256-264. [PMID: 37565530 PMCID: PMC10751946 DOI: 10.1017/s0007114523001794] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2023] [Revised: 07/28/2023] [Accepted: 08/07/2023] [Indexed: 08/12/2023]
Abstract
We aimed to study supplement use in relation to dietary intake among pregnant women in Sweden, and adherence to the Nordic Nutrition Recommendations among supplement and non-supplement users. Pregnant women were recruited at registration to antenatal care in 2013–2014. In third trimester, supplement use was collected using a questionnaire, and dietary intake was collected using a FFQ. The majority (64 %) of the 1044 women reported use of one or more supplements. Among all, 0–23 % reported dietary intakes above recommended intake (RI) of vitamin D, folate, Fe and Se. Median dietary intakes of thiamine (1·4 v. 1·3 mg P = 0·013), phosphorus (1482 v. 1440 mg P = 0·007), folate (327 v. 316 µg P = 0·02), Fe (12 v. 11·5 mg P = 0·009), Mg (361 v. 346 mg P < 0·001) and Zn (10·7 v. 10·4 mg P = 0·01) were higher among supplement users compared with non-users. Larger proportions of supplement users than non-users adhered to RI of dietary intakes of thiamine (42 % v. 35 % P = 0·04) and Mg (75 % v. 69 % P = 0·05). Among non-users, a minority had dietary intakes above RI for vitamin D (6 %), folate (10 %) and Fe (21 %). The majority (75–100 %) of supplement users had total intakes above RI for most nutrients. In conclusion, supplement use contributed substantially to reaching RI for vitamin D, folate and Fe. Supplement users had a higher dietary intake of several nutrients than non-users. This highlights that non-supplement users are at risk of inadequate nutrient intakes during pregnancy, suggesting a need for heightened awareness of nutritional adequacy for pregnant women.

[PMID: 37701189 PMCID: PMC10494575 DOI: 10.1002/fsn3.3482] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/23/2022] [Revised: 04/11/2023] [Accepted: 05/26/2023] [Indexed: 09/14/2023] Open
Abstract
Supplementation of certain micronutrients is recommended to ensure their adequate supply during pregnancy and lactation. In Germany, this applies particularly to folic acid and iodine. There is no nationwide data on adherence to the supplementation guidelines. The aim of this cross-sectional study was to determine the prevalence and predictors of the recommended supplementation of both folic acid and iodine in mothers of a nationwide birth cohort. Data on supplementation, before, during, and shortly after pregnancy, were collected retrospectively 14 days postpartum in a sample of 962 mother-infant pairs participating in the second nationwide study on breastfeeding and infant nutrition in Germany, called "SuSe II" (2017-2019). Folic acid and iodine supplementation were classified as recommended according to the German guidelines if supplementation was provided for both essential periods: for folic acid before and during pregnancy and for iodine during pregnancy and lactation. Univariable tests and multivariable logistic regression analysis were performed. The vast majority of mothers did not adhere to the recommendations, with only 36.2% supplementing folic acid and 31.9% supplementing iodine during the recommended periods, and only 15.2% adhering to the recommendations for both nutrients. Main predictors of adherence to recommendations of both nutrients were lifestyle attributes and nutrition-related intentions like previous breastfeeding experience and breastfeeding intentions, but not common sociodemographic characteristics. The data suggest widespread dissemination of the time-specific recommendations covering the entire period from preconception to lactation that could help to sensitize women and healthcare providers.

[PMID: 37069962 PMCID: PMC10105568 DOI: 10.2147/ijwh.s388656] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2022] [Accepted: 03/24/2023] [Indexed: 04/19/2023] Open
Abstract
Introduction Pregnant women are expected to take one or more dietary supplements (DS) like iron, folic acid, zinc, calcium, magnesium, prenatal vitamins, etc. for maternal and child health during pregnancy. Despite its growing use in Ethiopia, data concerning currently marketed maternal DS products have not been intensively investigated so far. Taking into consideration the existing problem, this study was set out to assess the prevalence and commonly used DS during pregnancy in a referral hospital in Ethiopia. Methods A facility based cross-sectional study was employed to conduct this study from November 2020 to January 2021. The sample size was obtained by using the single population proportion formula and participants were selected and approached by using a systematic random sampling technique. Data were collected through a semi-structured interviewer-administered questionnaire. Descriptive statistics including frequencies and percentages were used to describe continuous and categorical variables and multivariate logistic regression was used to observe the association of the independent variables to the dependent variable. Results The overall prevalence of DS use was 84.2% and the most used product was Fefol (iron and folate supplement) (62.4%). A majority (87.8%) of DS products were obtained by prescription. In multivariate regression analysis, DS use during pregnancy was significant among nulliparous women and women who went to college and above [adjusted odds ratio (AOR): 8.142, 95% confidence interval (CI) (1.298-51.070)] and [AOR: 9.259, 95% CI (1.998-42.906)], respectively. Conclusion Even though the prevalence of DS practice showed improvement among the study participants, the duration of the DS intake is less than that recommended by the WHO. Pregnant women who did not have birth before and who went to college or above showed significant association with the use of DS.

Abstract
This study aimed to investigate the dietary n-6:n-3 PUFA (polyunsaturated fatty acids) intake of pregnant Chinese women in different trimesters. We conducted a cross-sectional study for 300 singleton pregnant women in Hefei city, China. The dietary intake of pregnant women were measured by a 3-d food record. Energy and nutrient intake for the 3 d were calculated according to the Chinese food composition table (Standard Version). The ANOVA and Kruskal-Wallis test were performed to analyze the dietary fatty acids intake of pregnant women. In the first, second and third trimester, the intake of n-6:n-3 PUFA were 5.87±2.37, 6.03±2.89, 6.14±2.26, respectively, without significant difference (p>0.05). But it was all slightly higher than the recommendation for general population (4-6) of Chinese Nutrition Society. An adequate and balanced intake of n-6 and n-3 fatty acids, from a well-balanced diet, should be recommended for pregnant women.

Prenatal vitamin intake in first month of pregnancy and DNA methylation in cord blood and placenta in two prospective cohorts. Epigenetics Chromatin 2022; 15:28.

Abstract
BACKGROUND Prenatal vitamin use is recommended before and during pregnancies for normal fetal development. Prenatal vitamins do not have a standard formulation, but many contain calcium, folic acid, iodine, iron, omega-3 fatty acids, zinc, and vitamins A, B6, B12, and D, and usually they contain higher concentrations of folic acid and iron than regular multivitamins in the US Nutrient levels can impact epigenetic factors such as DNA methylation, but relationships between maternal prenatal vitamin use and DNA methylation have been relatively understudied. We examined use of prenatal vitamins in the first month of pregnancy in relation to cord blood and placenta DNA methylation in two prospective pregnancy cohorts: the Early Autism Risk Longitudinal Investigation (EARLI) and Markers of Autism Risk Learning Early Signs (MARBLES) studies. RESULTS In placenta, prenatal vitamin intake was marginally associated with -0.52% (95% CI -1.04, 0.01) lower mean array-wide DNA methylation in EARLI, and associated with -0.60% (-1.08, -0.13) lower mean array-wide DNA methylation in MARBLES. There was little consistency in the associations between prenatal vitamin intake and single DNA methylation site effect estimates across cohorts and tissues, with only a few overlapping sites with correlated effect estimates. However, the single DNA methylation sites with p-value < 0.01 (EARLI cord nCpGs = 4068, EARLI placenta nCpGs = 3647, MARBLES cord nCpGs = 4068, MARBLES placenta nCpGs = 9563) were consistently enriched in neuronal developmental pathways. CONCLUSIONS Together, our findings suggest that prenatal vitamin intake in the first month of pregnancy may be related to lower placental global DNA methylation and related to DNA methylation in brain-related pathways in both placenta and cord blood.

Food Supplement Use Differs from the Recommendations in Pregnant Women: A Multinational Survey. Nutrients 2022; 14:2909.

Abstract
The aim was to investigate, among pregnant women, (1) the use of food supplements and (2) the awareness of food supplement recommendations and beliefs about food supplement use in four European countries: Finland, Italy, Poland, and the United Kingdom. The participants (n = 1804) completed an online questionnaire with predefined statements. Daily intakes of vitamins and minerals were calculated using uploaded pictures or weblinks of the supplement packages. Country differences were assessed. Most participants (91%) used at least one food supplement during pregnancy. A prenatal multivitamin was the most commonly used supplement type (84% of the users), and 75% of the participants thought consumption of multivitamin is recommended. Of the participants, 81% knew that folic acid is recommended during pregnancy while 58% knew the recommendation for vitamin D. In 19% of the supplement users, the daily safe upper intake limit of at least one nutrient was exceeded. Nevertheless, most participants agreed that they knew which supplements (91%) and doses of supplements (87%) needed to be used during pregnancy. To conclude, the majority of the participants used food supplements, but lower proportions knew and adhered to the recommended intakes. Between-country differences were observed in the use and knowledge of and beliefs regarding supplements. The results suggest a need for assessment and monitoring of supplement use in antenatal care to ensure appropriate use.

Abstract
Dietary supplements sourced from marine environments, such as fish oils and seaweed-based supplements, are widely consumed to boost nutrient intakes, including by vulnerable populations such as pregnant women. Like other marine foods, these supplements are also a potential source of exposure to arsenic, including the known toxic species, inorganic arsenic, and the cytotoxic, lipid-soluble arsenic compounds, arsenic hydrocarbons. A study of 32 marine-sourced supplements found higher total arsenic concentrations (>1000 ng g-1) in supplements made from seaweed, krill and calanus oil, and in fish and fish liver products marketed as "unprocessed". Inorganic arsenic was only detectable in the seaweed samples, and was elevated (8900 ng g-1) in one product. Arsenic hydrocarbons were not detected in krill oil samples but were present at concentrations from 169 to 2048 ng g-1 in "unprocessed" fish and fish liver oil, and calanus oil. Survey data from the New Hampshire Birth Cohort Study (NHBCS) found 13.5% of pregnant women (n = 1997) reported taking fish oil supplements; and of those, most did so daily (75.6%, 6 or more times per week). Only a small percentage (9%) of those who reported consuming fish oil used products associated with higher arsenic levels. Higher urinary arsenic concentrations were found among women who consumed fish oil compared with those who did not, and specifically higher arsenobetaine and dimethyl arsenic concentrations. Dietary supplements are becoming common components of modern diets, and some marine-sourced dietary supplements are a source of inorganic arsenic and arsenic hydrocarbons.

Abstract
Introduction
The nutritional status of women before, during, and after pregnancy plays an important role in the health of mother and child. In addition to a balanced mixed diet, the
increased need for folic acid and iodine should be met and ensured with supplements. The aim of this study was to assess dietary supplementation in the context of pregnancy and to
investigate the effect of targeted counselling on supplementation behavior during and after pregnancy.
Methods
In the context of the “Gesund leben in der Schwangerschaft” (GeliS; “Healthy living in pregnancy”) trial, women in the intervention group (IG) received four structured
lifestyle counselling sessions during pregnancy as well as postpartum, during which they were informed about appropriate dietary supplementation. The women in the control group (CG) received
routine prenatal care. The intake of dietary supplements was recorded at different points using a questionnaire.
Results
In total, 2099 women were included in the analysis. Prior to conception, 31.3% of the women in the IG and 31.4% of the women in the CG took folic acid supplements.
Prenatally, about half of the women took folic acid (IG: 54.1%; CG: 52.0%) and iodine (IG: 50.2%; CG: 48.2%). Statistically significant differences between the groups with regard to
supplementation behavior could not be observed, neither prior to inclusion in the study nor during the intervention. During pregnancy, 23.0% of all women took docosahexaenoic acid (DHA)
supplements and 21.8% iron supplements. 49.4% of the women additionally took vitamin D supplements. A higher educational level (p < 0.001), advanced age (p < 0.001), primiparity
(p < 0.001), and a vegetarian diet (p = 0.037) were all associated with a higher level of dietary supplementation.
Conclusion
The GeliS lifestyle counselling did not significantly improve the supplementation behavior of women during and after pregnancy. Women should be informed about adequate
dietary supplementation early on within the scope of gynecological prenatal care.

Abstract
This study aimed to examine the prevalence, associated factors and perceptions of dietary supplement use among pregnant Chinese women. A cross-sectional study was conducted to collect data about prevalence, purchase channels, perceptions, and related factors of dietary supplement use from 572 pregnant women, through a face-to-face survey, using a self-designed questionnaire. Of the respondents, 94.8% used at least one dietary supplement, whereas 29.8% used more than four supplements in the previous month. The majority of the pregnant women were highly educated (81.2% had a bachelor’s degree or above) and had the perception that dietary supplements could prevent and improve (89.2%), or treat, nutrition-related diseases (78.7%). Multivariate analysis showed that pregnant women who had used multiple (more than four) supplements were more likely to have a larger gestational age, received fertility treatment, more prenatal visits, and hypothyroidism during pregnancy. Furthermore, pregnant women not only purchased dietary supplements through hospitals (72.6%) and pharmacies (45.1%), but overseas Daigou or online purchases (31.8%) were also a major channel of purchase. A high prevalence of dietary supplement use during pregnancy was observed, with extensive and repeated consumption of nutrients. Pregnant women’s craze for dietary supplements calls for more comprehensive guidelines in China.

Hoseini A, Dehdari T, Solhi M, Rahideh ST, Janani L. Qualitative exploration of the factors influencing the use of dietary supplements in Iranian women: introduction to areas of focus for developing interventions. Heliyon 2021; 7:e06672. [PMID: 33889781 PMCID: PMC8049998 DOI: 10.1016/j.heliyon.2021.e06672] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2020] [Revised: 03/16/2021] [Accepted: 03/30/2021] [Indexed: 11/29/2022] Open
Abstract
BACKGROUND Literature shows that the consumption of Dietary Supplements (DS) is more common in Iran. This study aimed to explore the experiences of a sample of Iranian women regarding the factors influencing the use of DS. METHODS This qualitative content analysis study was conducted in Qods city, Tehran province, Iran from January to March 2020. Forty-two semi-structured in-depth interviews were performed with women. The participants were asked about their experiences about the determinants of the consumption of DS. After the first round of the interviews was done, we performed content analysis of the data and continued up to data saturation. RESULTS Two main themes including personal factors (with 5 subthemes including sociodemographic characteristics, perceived benefits of DS, history of illness, physiological conditions, and lifestyle factors) and socio-economic factors (with 3 subthemes including subjective norms, the price of food and commercial considerations of the sectors involved in the production and sale of DS) emerged as the experiences of the participants as to the intake of DS. CONCLUSIONS These variables may suggest areas which need to be focused on for performing more effective interventions to affect appropriate consumption of DS in Iran.

Prenatal Multivitamin Use and MTHFR Genotype Are Associated with Newborn Cord Blood DNA Methylation. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:ijerph17249190. [PMID: 33317014 PMCID: PMC7764679 DOI: 10.3390/ijerph17249190] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/05/2020] [Revised: 11/20/2020] [Accepted: 11/28/2020] [Indexed: 12/20/2022]
Abstract
Background: Fetal development involves cellular differentiation and epigenetic changes—complex processes that are sensitive to environmental factors. Maternal nutrient levels during pregnancy affect development, and methylene tetrahydrofolate reductase (MTHFR) is important for processing the nutrient folate. Hypothesis: We hypothesize that supplement intake before pregnancy and maternal genotype are associated with DNA methylation in newborns. Methods: In the pregnancy cohort, Early Autism Risk Longitudinal Investigation (EARLI), health history, and genotype information was obtained (n = 249 families). Cord blood DNA methylation (n = 130) was measured using the Illumina HumanMethylation450k array and global DNA methylation levels were computed over 455,698 sites. Supplement use preconception and during pregnancy were surveyed at visits during pregnancy. We evaluated associations between maternal preconception supplement intake and global DNA methylation or DNA methylation density distributions of newborn cord blood, stratified by the presence of a variant maternal MTHFR C677T allele. Results: Maternal preconceptional multivitamin intake was associated with cord blood methylation, dependent on maternal MTHFR genotype (interaction term p = 0.013). For mothers without the MTHFR variant allele, multivitamin intake was associated with 0.96% (95% CI: 0.09, 1.83) higher global cord blood methylation (p = 0.04) and was also associated with the cumulative density distribution of methylation (p = 0.03). For mothers with at least one variant allele, multivitamin intake had a null −0.06% (95% CI: −0.45, 0.33) association with global cord blood DNA methylation, and was not associated with the cumulative density distribution (p = 0.37). Conclusions: We observed that cord blood DNA methylation was associated with maternal supplement exposure preconception and maternal genotype. Genetic context should be considered when assessing DNA methylation effects of modifiable risk factors around the time of pregnancy.

Abstract
OBJECTIVE To provide updated information about demographic variations and temporal trends in the prenatal use of multiple micronutrient (MMN) supplements in the metropolitan areas of China. DESIGN Descriptive analysis of routine prenatal healthcare data between 2013 and 2017. SETTING Chaoyang District, Beijing, China. PARTICIPANTS A total of 197 346 pregnant women who attended their first prenatal care visit and provided information about MMN supplementation during the periconceptional period. RESULTS Of these pregnant women, 60·6 % reported consuming prenatal MMN supplements. In multivariate-adjusted models, there were significant gradients of age, education and parity in prenatal MMN supplementation, with the highest likelihood of MMN use among the oldest, the most highly educated and nulliparous women (Pfor trend < 0·001). Compared with that among unemployed women, prenatal MMN supplementation was more common among the employed, especially those engaged in business (adjusted relative risks (95 % CI): 1·08 (1·06, 1·10)) and management (1·10 (1·08, 1·12)). The proportion of prenatal MMN supplementation was 57·0 % in 2013, which increased to 63·5 % in 2017 (Pfor trend < 0·001). The trends varied by age, education and parity (Pfor heterogeneity < 0·001), whereas no significant difference was observed in trends across subgroups of ethnicity or occupation. The greatest magnitude increase in MMN supplement use occurred in women of age < 25 years (annual percent change: 5·7 %), less than high school education (9·6 %), parity ≥ 2 (6·8 %) or unemployment (6·1 %). CONCLUSION Approximately two-thirds of women consumed prenatal MMN supplements during the periconceptional period in the central area of Beijing and the proportion increased over time, indicating a need to evaluate the effectiveness and safety and to develop a guideline for relatively well-nourished women.

Abstract
OBJECTIVES To assess the knowledge and intake of folic acid among teachers of childbearing age and to identify barriers to folic acid intake. SETTING Governmental schools, which included 14 primary models, 29 primary, 14 preparatory and 16 secondary schools. The proportion of teachers in each stratum was then determined, and a stratified random sampling design had been used with proportional allocation. STUDY DESIGN Cross-sectional study PARTICIPANTS: A total of 406 non-pregnant teachers of childbearing age enrolled in the study. A validated questionnaire in the Arabic language was used. RESULTS The overall response rate was 98%. About 34.6% reported the optimal period in which they should take folic acid, 28.3% reported the correct intake duration and only 29.5% could name food rich in folic acid. Friends and healthcare providers were the main sources of information for the participants; however, 44% said that they did not receive enough information from their healthcare providers. CONCLUSION There is a lack of knowledge and poor intake of folic acid among the participants. In particular, they lacked information about the appropriate time to start folic acid supplementations, the duration of intake and the folic acid-rich food. The most common reason being the limited advice given by their healthcare providers.Awareness campaigns are recommended to emphasise the role of healthcare providers in counselling women about the proper use of folic acid before pregnancy.

Abstract
OBJECTIVE We investigated the association between maternal use of vitamin D and omega-3 fatty acids (n-3 FAs) supplements during pregnancy and risk of islet autoimmunity (IA) in the offspring. METHODS The Environmental Determinants of Diabetes in the Young (TEDDY) Study is prospectively following 8676 children with increased genetic risk for type 1 diabetes in Finland, Germany, Sweden, and the United States. Blood samples were collected every 3 months between 3 and 48 months of age then every 6 months thereafter to determine persistent IA. Duration, frequency, and supplement dose during pregnancy were recalled by mothers at 3 to 4 months postpartum. Cumulative intakes of supplemental vitamin D and n-3 FAs were analyzed as continuous or binary variables. We applied time-to-event analysis to study the association between maternal supplement use and IA, adjusting for country, human leukocyte antigen-DR-DQ genotype, family history of type 1 diabetes and sex. Secondary outcomes included insulin autoantibodies (IAA) or glutamic acid decarboxylase (GADA) as the first appearing autoantibody. RESULTS As of February 2018, there were 747 (9.0%) children with IA. Vitamin D supplement intake during pregnancy (any vs none) was not associated with risk for IA (hazard ratio [HR] 1.11; 95% confidence interval [CI] 0.94, 1.31); neither was cumulative vitamin D supplement intake. Supplemental n-3 FA intake was similarly not associated with IA risk (HR: 1.19, 95% CI 0.98, 1.45). Similar lack of association was observed for either IAA or GADA as the first appearing autoantibody. CONCLUSIONS The TEDDY cohort showed no evidence of benefit regarding IA risk for vitamin D or n-3 FA supplementation during pregnancy.

Abstract
Objective: The study was aimed at determining the characteristics and lifestyle choices of dietary supplement users and to assess knowledge, attitude, and practice related to dietary supplements in the health sciences students versus other individuals in Saudi Arabia. Methods: A descriptive cross-sectional, online questionnaire-based study was conducted on 351 participants (138 were health sciences students and 203 were not). The results were documented and analyzed using SPSS- version 22. Results: More than half of the participants consumed dietary supplements, 53.6% of the health sciences students versus 56.3% of the other individuals. Multivitamins were the most commonly used supplement in all participants (49%). Both groups believed that people might need dietary supplements more during specific times as pregnancy or recovery from diseases, with higher percentage in health sciences students than other people (43% versus 38%). Most of the students were somewhat aware about the facts concerning dietary supplements compared to others. Significant difference (P ≤ 0.05) was found concerning opinion and beliefs related to dietary supplements between the two groups. However, the health sciences students were not highly knowledgeable about the facts regarding supplements. Conclusion: The users of dietary supplements tend to incorporate these products into their lifestyles as part of a broader focus on healthy living. Many of health sciences students do not have accurate information about dietary supplements. It is important to strengthen the health science curriculum concerning this topic, with the aim of producing better-informed future professionals.

Abstract
PURPOSE OF REVIEW The environmental triggers of islet autoimmunity leading to type 1 diabetes (T1D) need to be elucidated to inform primary prevention. The Environmental Determinants of Diabetes in the Young (TEDDY) Study follows from birth 8676 children with T1D risk HLA-DR-DQ genotypes in the USA, Finland, Germany, and Sweden. Most study participants (89%) have no first-degree relative with T1D. The primary outcomes include the appearance of one or more persistent islet autoantibodies (islet autoimmunity, IA) and clinical T1D. RECENT FINDINGS As of February 28, 2018, 769 children had developed IA and 310 have progressed to T1D. Secondary outcomes include celiac disease and autoimmune thyroid disease. While the follow-up continues, TEDDY has already evaluated a number of candidate environmental triggers, including infections, probiotics, micronutrient, and microbiome. TEDDY results suggest that there are multiple pathways leading to the destruction of pancreatic beta-cells. Ongoing measurements of further specific exposures, gene variants, and gene-environment interactions and detailed "omics" studies will provide novel information on the pathogenesis of T1D.

Abstract
An adequate nutritional status during the preconception period is important, particularly for folate, vitamin D, and n-3 fatty acids (i.e., EPA+DHA). We aimed to determine supplement intake and the main dietary sources of folate, vitamin D, and EPA+DHA using the data of 66 Dutch women aged 18–40 years who wished to become pregnant. Additionally, associations of these intakes with their blood levels were examined. Dietary intake was assessed with a validated food frequency questionnaire, and supplement use with a structured questionnaire. 25-hydroxyvitamin D levels were determined in serum and folate and phospholipid EPA+DHA levels in plasma. Partial Spearman’s correlations, restricted cubic splines and trend analyses over tertiles of nutrient intakes were performed to examine intake-status associations. A large proportion of women did not meet the Dutch recommended intakes of folate (50%), vitamin D (67%), and EPA+DHA (52%). Vegetables were the main contributor to dietary folate intake (25%), oils and fats to dietary vitamin D intake (39%), and fish to dietary EPA+DHA intake (69%). Fourteen percent of the women had an inadequate folate status and 23% an inadequate vitamin D status. Supplemental folate intake, supplemental and dietary vitamin D intake and dietary EPA+DHA intake were significantly associated with their blood levels. In conclusion, even in our highly educated population, a large proportion did not achieve recommended folate, vitamin D and n-3 fatty acid intakes. Promotion of folate and vitamin D supplement use and fish consumption is needed to improve intakes and blood levels of these nutrients in women who wish to become pregnant.

Abstract
OBJECTIVE Inadequate maternal micronutrient status during pregnancy can lead to short- and long-term health risks for mother and offspring. The present study investigated the association between pre-pregnancy weight status and micronutrient status during pregnancy. DESIGN Maternal blood samples were collected during early pregnancy (median 13, interquartile range 12-15 weeks) and were assayed for serum folate, ferritin, Fe and vitamin B12. Regression modelling was used to assess the association between pre-pregnancy underweight, normal weight, overweight and obesity, and micronutrient levels, as well as the odds for deficiencies. SETTING The Amsterdam Born Children and their Development (ABCD) study, the Netherlands. SUBJECTS Women with singleton pregnancies without diabetes (n 4243). RESULTS After adjustment for covariates, overweight women and obese women had lower (β; 95 % CI) folate (-1·2; -2·2, -0·2 and -2·3; -4·0, -0·7 nmol/l, respectively) and Fe (-1·7; -2·3, -1·1 and -3·6; -4·7, -2·6 μmol/l, respectively) levels than women with normal weight. Furthermore, overweight women had 6 % (95 % CI -9, -3 %) and obese women had 15 % (-19, -10 %), lower vitamin B12 levels, and obese women had 19 % (6, 32 %) higher ferritin levels, than normal-weight women. Obese women had higher odds (OR; 95 % CI) for folate deficiency (2·03; 1·35, 3·06), Fe deficiency (3·26; 2·09, 5·08) and vitamin B12 deficiency (2·05; 1·41, 2·99) than women with normal weight. Underweight was not associated with micronutrient status. CONCLUSIONS During early pregnancy, women with pre-pregnancy overweight and obesity had lower serum folate, Fe and vitamin B12 status. This resulted in increased risk of serum folate, Fe and vitamin B12 deficiencies in women with obesity.

Abstract
Sociodemographic factors have been associated with dietary supplement use among pregnant women but few data exist in a Swedish population. This study aimed to identify factors associated with overall supplement use as well as use of folic acid, vitamin D and n-3 in early pregnancy. Women in the first trimester of pregnancy were included at registration to the antenatal care in 2013-2014 (n 2109). Information regarding supplement use as well as sociodemographic and anthropometric data were obtained from questionnaires and medical records. Multivariable logistic regression analysis was performed to determine the relationship between sociodemographic variables and supplement use. A total of 78 % of the participants reported using at least one dietary supplement in the first trimester. Folic acid supplement use was reported by 74 %, vitamin D supplement use by 43 % and n-3 supplement use by <5 %. Use of any type of supplement in early pregnancy was related to gestational age, parity, birthplace, education and employment. Folic acid supplement use was related to gestational age, parity, birthplace, income, education and employment. Vitamin D supplement use was related to gestational age, birthplace and education. In conclusion, in the first trimester of pregnancy, folic acid supplements were used by three in four women, while vitamin D supplements were used by less than half of the women. The results of this study show a socioeconomic disparity between supplement users and non-users which may have a negative impact on the health of future generations.

Abstract
BACKGROUND/OBJECTIVES Vitamin D and probiotics are nutrients of interest in the context of type 1 diabetes (T1D). We assessed the prevalence of and factors associated with vitamin D and probiotic supplementations among young children with genetic risk of T1D. SUBJECTS/METHODS Use of supplements during the first 2 years of life was collected prospectively from 8674 children in The Environmental Determinants of Diabetes in the Young (TEDDY) study. RESULTS Single and/or multivitamin/mineral (MVM) supplements were reported by 81% of the children. The majority of participants in Finland, Germany and Sweden (97-99%) and 50% in the United States received vitamin D supplements that were mostly MVMs. Probiotics use varied from 6% in the United States to 60% in Finland and was primarily from probiotics-only preparations. More than 80% of the vitamin D and probiotics supplementation was initiated during infancy, and more than half of the uses lasted longer than a year. Being the first child, longer duration of breastfeeding, born in a later year, older maternal age and higher maternal education level were associated with both vitamin D and probiotics use. Shorter gestational age and mother not smoking during pregnancy were associated with a higher likelihood of probiotics supplementation only. CONCLUSIONS Vitamin D and probiotics supplementations are popular in children 0-2 years old and are associated with common factors. Data documented here will allow evaluation of the relationship between early childhood dietary intake and the development of islet autoimmunity and progression to T1D.

Abstract
Background The aim was to investigate the prevalence of dietary supplement use among pregnant Saudi women and its associations between various demographics. Methods In this cross-sectional study, a total of 137 pregnant women attending prenatal care from King Salman Hospital completed a self-administered questionnaire including socio-demographic characteristics, general awareness, attitude and behavior towards use of dietary supplements during pregnancy. Results Dietary supplement use among Saudi women in pregnancy was high (71.5%) and was significantly associated with level of education (p = 0.005), family income (p = 0.039) and number of children (p = 0.007). No significant association was observed between neonatal health outcomes and dietary supplement use during pregnancy. In all participants, 81.6% believed that supplement use is important for nutritional status and more favorable neonatal outcomes. For the majority of participants, the primary source of information for dietary supplement use was a doctor’s advice. The majority of the participants [65.7% (n = 90)] responded that dietary supplement use is safe. Folic acid was found to be the most common type of dietary supplement used (95.9%; n = 94); however, 53.1% (n = 52) did not take folic acid supplements 3 months prior to pregnancy. Other common supplements used were iron, calcium and vitamin D (88.8, 81.6, and 41%, respectively). Conclusions This study provided new information on dietary supplement use and its correlates in Saudi pregnant women. The prevalence of dietary supplement use was high in this group and was associated with socio-demographic and lifestyle characteristics.

Neonatal vitamin D status from archived dried blood spots and future risk of fractures in childhood: results from the D-tect study, a population-based case-cohort study. Am J Clin Nutr 2017; 106:155-161. [PMID: 28515065 DOI: 10.3945/ajcn.116.145599] [Citation(s) in RCA: 20] [Impact Index Per Article: 2.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2016] [Accepted: 04/19/2017] [Indexed: 11/14/2022] Open
Abstract
Background: Whether antenatal and neonatal vitamin D status have clinical relevance in fracture prevention has not been examined extensively, although observational studies indicate that fetal life may be a sensitive period in relation to bone growth and mineralization during childhood.Objective: We examined whether 25-hydroxyvitamin D3 [25(OH)D3] concentrations in stored neonatal dried blood spot (DBS) samples are associated with pediatric fracture risk. We hypothesized that in particular, low neonatal vitamin D status may be a risk factor for fracture incidence among children.Design: In a register-based case-cohort study design, the case group was composed of 1039 individuals who were randomly selected from a total of 82,154 individuals who were born during 1989-1999 and admitted to a Danish hospital with a fracture of the forearm, wrist, scaphoid bone, clavicle, or ankle at age 6-13 y. The subcohort was composed of 1600 individuals randomly selected from all Danish children born during 1989-1999. The neonatal 25(OH)D3 concentrations in DBS samples were assessed by using highly sensitive chromatography-tandem mass spectrometry.Results: The mean ± SD 25(OH)D3 concentration for all subjects was 27.7 ± 18.9 nmol/L [median (IQR): 23.5 nmol/L (13.3, 37.3 nmol/L)] and showed significant monthly variation (P < 0.0001) with the highest values in July and August. Individuals in the middle quintile of neonatal 25(OH)D3 had lower odds of sustaining a fracture than did those in the lowest quintile (adjusted OR: 0.75; 95% CI: 0.58, 0.96), but a global test did not show any significant overall association (adjusted P = 0.13).Conclusions: This study suggested that neonatal vitamin D status does not influence subsequent fracture risk in childhood. This is in accordance with studies that report no association between antenatal maternal vitamin D status and childhood fractures. Further studies are needed to examine fracture risk in relation to prenatal vitamin D status in a randomized controlled setting.

Is Nutrient Content and Other Label Information for Prescription Prenatal Supplements Different from Nonprescription Products? J Acad Nutr Diet 2017; 117:1429-1436. [PMID: 28571654 DOI: 10.1016/j.jand.2017.04.002] [Citation(s) in RCA: 24] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2016] [Accepted: 04/03/2017] [Indexed: 12/19/2022]
Abstract
BACKGROUND Prenatal supplements are often recommended to pregnant women to help meet their nutrient needs. Many products are available, making it difficult to choose a suitable supplement because little is known about their labeling and contents to evaluate their appropriateness. OBJECTIVE To determine differences between prescription and nonprescription prenatal supplements available in the United States regarding declared nutrient and nonnutrient ingredients and the presence of dosing and safety-related information. DESIGN Using two publicly available databases with information about prenatal supplement products, information from prescription and nonprescription product labels were extracted and evaluated. For the 82 prescription and 132 nonprescription products, declared label amounts of seven vitamins and minerals, docosahexaenoic acid (DHA), the presence of other nonnutrient components, and the presence of key safety and informational elements as identified in two Department of Health and Human Services Office of Inspector General (OIG)'s 2003 reports were compiled and compared. RESULTS Compared with nonprescription products, prescription products contained significantly fewer vitamins (9±0.2 vs 11±0.3; P≤0.05) and minerals (4±0.1 vs 8±0.3; P≤0.05). Declared amounts of folic acid were higher in prescription products, whereas vitamin A, vitamin D, iodine, and calcium were higher in the nonprescription products. Amounts of iron, zinc, and DHA were similar. Virtually all products contained levels of one or more nutrients that exceeded the Recommended Dietary Allowances for pregnant and/or lactating women. Product type also influenced ingredients added. Fewer prescription products contained botanical ingredients (6% prescription vs 33% nonprescription) and probiotics (2% prescription vs 8% nonprescription). Only prescription products contained the stool softener docusate sodium. CONCLUSIONS Our analysis of prenatal supplements indicates that prescription and nonprescription supplements differ in terms of declared composition and nutrient strength, but have labels that are similarly sparse regarding aspects of use such as dosing information.

Abstract
Perinatal exposure to nutrients and dietary components may affect the risk for coeliac disease (CD). We investigated the association between maternal use of vitamin D, n-3 fatty acids (FA) and Fe supplements during pregnancy and risk for CD autoimmunity (CDA) and CD in the offspring. Children at increased genetic risk were prospectively followed from birth in The Environmental Determinants of Diabetes in the Young (TEDDY) study. CDA was defined as having persistently positive tissue transglutaminase autoantibodies (tTGA). Diagnosis of CD was either biopsy-confirmed or considered likely if having persistently elevated levels of tTGA>100 AU. Of 6627 enrolled children, 1136 developed CDA at a median 3·1 years of age (range 0·9-10) and 409 developed CD at a median 3·9 years of age (range 1·2-11). Use of supplements containing vitamin D, n-3 FA and Fe was recalled by 66, 17 and 94 % of mothers, respectively, at 3-4 months postpartum. The mean cumulative intake over the entire pregnancy was 2014 μg vitamin D (sd 2045 μg), 111 g n-3 FA (sd 303 g) and 8806 mg Fe (sd 7017 mg). After adjusting for country, child's human leucocyte antigen genotype, sex, family history of CD, any breast-feeding duration and household crowding, Cox's proportional hazard ratios did not suggest a statistically significant association between the intake of vitamin D, n-3 FA or Fe, and risk for CDA or CD. Dietary supplementation during pregnancy may help boost nutrient intake, but it is not likely to modify the risk for the disease in the offspring.

Abstract
BACKGROUND Sweden has the second highest incidence of type 1 diabetes in the world. Nutritional aspects in utero and in infancy affect the development. We conducted a survey to determine whether reported maternal use of vitamin D-containing micronutrient supplements during pregnancy was associated with the risk of developing type 1 diabetes in the child. METHODS This report was based on data from the ABIS (All Babies In Southeast Sweden) study, with questionnaire data on 16 339 mother and infant pairs at birth and at 1-yr of age (n = 10 879), of whom 108 children were registered with type 1 diabetes before 14-16 yr of age. The questions 'during pregnancy, did you take any vitamin/mineral supplements?' and 'if yes, which? (open answer)' in addition to other lifestyle questions were answered. Logistic regression was performed with onset of type 1 diabetes as the dependent variable and vitamin D supplementation use as the independent variable, adjusted for relevant factors. RESULTS Vitamin D supplementation during pregnancy was consumed by 9.3% of mothers whose children later got type1 diabetes and among 11.3% of those mothers whose children did not get type 1 diabetes (p = 0.532). No significant association was found between reported supplement intake of vitamin D during pregnancy and risk of type 1 diabetes, even when adjusting for factors which could influence the association. CONCLUSION Maternal use of vitamin D-containing multivitamin supplements during pregnancy was not related to the risk of developing type 1 diabetes in children before 14-16 yr of age in Southeast of Sweden.

Abstract
OBJECTIVE To examine overall micronutrient intake periconceptionally and throughout pregnancy in a population-based cohort of Australian women. DESIGN In a prospective cohort study, micronutrient dosages were extracted from self-reported maternal supplement use, recorded pre-conception, and for each trimester of pregnancy. A food frequency scale (DQESv2) captured usual maternal diet for gestational weeks 14-26. The influence of sociodemographic and lifestyle factors associated with supplement use was examined using logistic regression, and changes in micronutrient intakes prior to and throughout pregnancy were assessed using repeated-measures ANOVA analyses. SETTING Metropolitan hospital sites in Melbourne, Australia. SUBJECTS Women with a viable singleton pregnancy were recruited at less than 19 weeks' gestation (n 2146). RESULTS Compared with non-users, women using supplements during pregnancy were more likely to have planned their pregnancy, be >25 years old, primiparous, Caucasian, non-smokers, have a tertiary education and be consuming a folate-rich diet. Intakes of folate, Fe and Zn were significantly lower in the periconceptional period, compared with other periods (P<0·001). Intakes below Recommended Daily Intake levels were common both periconceptionally and throughout pregnancy, with 19-46 % of women not meeting the Recommended Daily Intake for folate, 68-82 % for Fe and 17-36 % for Zn. Conversely, 15-19 % of women consumed beyond the recommended Upper Limit for folate and 11-24 % for Fe. CONCLUSIONS The study highlights the need for improved public health education on nutritional needs during pregnancy, especially among women with lower educational achievements and income.

Abstract
Increased growth in early childhood has been suggested to increase the risk of type 1 diabetes. This study explored the relationship between weight or height and development of persistent islet autoimmunity and progression to type 1 diabetes during the first 4 years of life in 7,468 children at genetic risk for type 1 diabetes followed in Finland, Germany, Sweden, and the U.S. Growth data collected every third month were used to estimate individual growth curves by mixed models. Cox proportional hazards models were used to evaluate body size and risk of islet autoimmunity and type 1 diabetes. In the overall cohort, development of islet autoimmunity (n = 575) was related to weight z scores at 12 months (hazard ratio [HR] 1.16 per 1.14 kg in males or per 1.02 kg in females, 95% CI 1.06-1.27, P < 0.001, false discovery rate [FDR] = 0.008) but not at 24 or 36 months. A similar relationship was seen between weight z scores and development of multiple islet autoantibodies (1 year: HR 1.21, 95% CI 1.08-1.35, P = 0.001, FDR = 0.008; 2 years: HR 1.18, 95% CI 1.06-1.32, P = 0.004, FDR = 0.02). No association was found between weight or height and type 1 diabetes (n = 169). In conclusion, greater weight in the first years of life was associated with an increased risk of islet autoimmunity.

Abstract
INTRODUCTION Little is known about the changes in prevalence of dietary supplement use in pregnancy, postpartum, and in a comparison group of nonpregnant women. METHODS We conducted a secondary analysis of the Infant Feeding Practices II study. The purpose of this study is to report the prevalence of herbal or botanical and nonvitamin, nonmineral dietary supplement use by US women with respect to demographic, behavioral, and health factors. We compared pregnant and postpartum women to a comparison group of nonpregnant women who had not given birth in the past 12 months. Our main outcome was the prevalence of dietary supplements. Multiple logistic regression models were used to examine factors associated with herbal or botanical and nonvitamin, nonmineral dietary supplement use during reproductive age, pregnancy, and postpartum. RESULTS The total sample included 1444 women assessed during the prenatal period, 1422 from the postpartum period, and 1517 women in a comparison group. In terms of herb or botanical use, 15% of the prenatal group, 16% of the postpartum group, and 22% of the comparison group reported using herbs or botanicals. The most frequently used nonvitamin, nonmineral supplement was omega-3 fatty acid. Among the total prenatal group and comparison group, women eating 5 or more servings of fruits or vegetables were less likely to report using herbs or botanicals. Women in the comparison group self-identifying as black were 4 times as likely to report using herbs or botanicals compared to participants self-identifying as white. In addition, women identifying as a race other than white were almost twice as likely to report herb or botanical use across all study groups. DISCUSSION This is one of the rare studies that shows the changing prevalence of herbs or botanicals and nonvitamin, nonmineral dietary supplement use in women in the reproductive stage of their lives.

Abstract
OBJECTIVE(S) To validate the Block98 food frequency questionnaire (FFQ) for estimating antioxidant, methyl-nutrient and polyunsaturated fatty acids (PUFA) intakes in a pregnant sample of ethnic/racial minority women in the United States (US). METHODS Participants (n = 42) were from the Programming of Intergenerational Stress Mechanisms study. Total micronutrient intakes from food and supplements was ascertained using the modified Block98 FFQ and two 24-h dietary recalls collected at random on nonconsecutive days subsequent to completion of the FFQ in mid-pregnancy. Correlation coefficients (r) corrected for attenuation from within-person variation in the recalls were calculated for antioxidants (n = 7), methyl-nutrients (n = 8), and PUFAs (n = 2). RESULT(S) The sample was largely ethnic minorities (38 % Black, 33 % Hispanic) with 21 % being foreign born and 41 % having less than or equal to a high school degree. Significant and adequate deattenuated correlations (r ≥ 0.40) for total dietary intakes of antioxidants were observed for vitamin C, vitamin E, magnesium, and zinc. Reasonable deattenuated correlations were also observed for methyl-nutrient intakes of vitamin B6, betaine, iron, and n:6 PUFAs; however, they did not reach significance. Most women were classified into the same or adjacent quartiles (≥70 %) for total (dietary + supplements) estimates of antioxidants (5 out of 7) and methyl-nutrients (4 out of 5). CONCLUSIONS The Block98 FFQ is an appropriate dietary method for evaluating antioxidants in pregnant ethnic/minorities in the US; it may be less efficient in measuring methyl-nutrient and PUFA intakes.

Abstract
BACKGROUND To investigate ethnic differences in vitamin D levels during pregnancy, assess risk factors for vitamin D deficiency and explore the effect of vitamin D supplementation in women with deficiency in early pregnancy. METHODS This is a population-based, multiethnic cohort study of pregnant women attending Child Health Clinics for antenatal care in Oslo, Norway. Serum-25-hydroxyvitamin D [25(OH)D] was measured in 748 pregnant women (59% ethnic minorities) at gestational weeks (GW) 15 (SD:3.6) and 28 (1.4). Women with 25(OH)D <37 nmol/L at GW 15 were for ethical reasons recommended vitamin D3 supplementation. Main outcome measure was 25(OH)D, and linear regression models were performed. RESULTS Severe deficiency (25(OH)D <25 nmol/L) was found at GW 15 in 45% of women from South Asia, 40% from the Middle East and 26% from Sub-Saharan Africa, compared to 2.5% in women from East Asia and 1.3% of women from Western Europe. Women from South Asia, the Middle East and Sub-Saharan Africa had mean values that were -28 (95 % CI:-33, -23), -24 (-29, -18) and -20 (-27, -13) nmol/L lower than in Western women, respectively. Ethnicity, education, season and intake of vitamin D were independently associated with 25(OH)D. At GW 28, the mean 25(OH)D had increased from 23 (SD:7.8) to 47 (27) nmol/L (p < 0.01) in women who were recommended vitamin D supplementation, with small or no change in women with sufficient vitamin D levels at baseline. CONCLUSIONS Vitamin D deficiency was prevalent among South Asian, Middle Eastern and African women. The serum levels of 25(OH)D increased significantly from GW 15 to 28 in vitamin D deficient women who received a recommendation for supplementation. This recommendation of vitamin D supplementation increased vitamin D levels in deficient women.

Abstract
Background There are few data focusing on the prevalence of vitamin D deficiency in tropical countries. Objectives We determined the vitamin D status in pregnant women and examined the factors associated with vitamin D deficiency. Design and Methods A cross-sectional study of 147 pregnant Thai women aged 18–45 years at Siriraj Hospital (a university hospital in Bangkok, Thailand) was undertaken. Clinical data and plasma levels of 25-hydroxyvitamin D [25(OH)D], intact parathyroid hormone (iPTH), calcium, albumin, phosphate and magnesium were obtained in pregnant women at delivery. Results The prevalence of hypovitaminosis D [defined as 25(OH)D <75 nmol/L] in pregnant women at delivery was 75.5% (95% confidence interval (CI), 67.7–82.2%). Of these, vitamin D insufficiency [defined as 25(OH)D 50–74.9 nmol/L] was found in 41.5% (95% CI, 33.4–49.9%) and vitamin D deficiency [25(OH)D <50 nmol/L] was found in 34.0% (95% CI, 26.4–42.3%) of women. The mean 25(OH)D concentration was 61.6±19.3 nmol/L. The correlation between 25(OH)D and iPTH was weak (r = –0.29, P<0.01). Factors associated with vitamin D deficiency by multiple logistic regression were: pre-pregnancy body mass index (BMI in kg/m2, odds ratio (OR), 0.88, 95% CI 0.80–0.97, P = 0.01) and season of blood collection (winter vs. rainy, OR, 2.62, 95% CI 1.18–5.85, P = 0.02). Conclusions Vitamin D deficiency is common among pregnant Thai women. The prevalence of vitamin D deficiency increased in women who had a lower pre-pregnancy BMI and whose blood was collected in the winter. Vitamin D supplementation may need to be implemented as routine antenatal care.

Abstract
Background The prevalence of gestational diabetes (GDM) has been increasing along with the obesity pandemic. It is associated with pregnancy complications and a risk of type 2 diabetes. Objective To study nutrient intake among pregnant Finnish women at increased risk of GDM due to obesity or a history of GDM. Design Food records from obese women or women with GDM history (n=394) were examined at baseline (≤20 weeks of pregnancy) of the Finnish Gestational Diabetes Prevention Study. Results The pregnant women had a mean fat intake of 33 en% (SD 7), saturated fatty acids (SFA) 12 en% (SD 3), and carbohydrate 46 en% (SD 6). Sucrose intake among pregnant women with GDM history was 7 en% (SD 3), which was different from the intake of the other pregnant women, 10 en% (SD 4) (p<0.001). Median intakes of folate and vitamins A and D provided by food sources were below the Finnish national nutrition recommendation, but, excluding vitamin A, supplements raised the total intake to the recommended level. The frequency of use of dietary supplements among pregnant women was 77%. Conclusions The observed excessive intake of SFA and low intake of carbohydrates among women at high risk of GDM may further increase their risk of GDM. A GDM history, however, seems to reduce sucrose intake in a future pregnancy. Pregnant women at high risk of GDM seem to have insufficient intakes of vitamin D and folate from food and thus need supplementation, which most of them already take.

Abstract
Background There is a highly variable asymptomatic period of beta cell destruction prior to the clinical presentation of type1 diabetes. It is not well known what triggers type 1 diabetes to become a clinically overt disease. This explorative study aimed to identify the association between disease history/medication use and the clinical manifestation of type 1 diabetes. Methodology/Principal Findings An explorative case control study was conducted in the Dutch PHARMO Record Linkage System. Cases (n = 1,107) were younger than 25 years and had at least 2 insulin prescriptions between 1999 and 2009. For each case, up to 4 controls (without any prescription for the glucose lowering medications (n = 4,424)) were matched by age and sex. Conditional logistic regression analysis was used to evaluate the association between disease history/medication use in the year prior to the diagnosis of type1 diabetes and clinical manifestation of this disease. Type1 diabetes was significantly associated with a history of mental disorder (odds ratio (OR) 8.0, 95% confidence interval (CI) 1.5–43.7), anemia (OR 5.1, 95% CI 1.1–22.9), and disease of digestive system (OR 2.6, 95% CI 1.2–5.5). The following drug exposures were significantly associated with the clinical manifestation of type 1 diabetes: “systemic hormonal preparations” (OR 1.7, 95% CI 1.1–2.6), medications for “blood and blood forming organs” (OR 1.6, 95% CI 1.1–2.6), “alimentary tract and metabolism” (OR 1.3, 95% CI 1.1–1.6), and “anti-infectives for systemic use” (OR 1.2, 95% CI 1.01–1.4). Conclusions Our explorative study demonstrated that in the year prior to the presentation of type1 diabetes in children and young adults, hospitalization for a diverse group of diseases and drug exposures were significantly more prevalent compared with age- and sex-matched diabetes-free controls.

The high prevalence of vitamin D deficiency and its related maternal factors in pregnant women in Beijing. PLoS One 2013; 8:e85081. [PMID: 24386450 PMCID: PMC3873449 DOI: 10.1371/journal.pone.0085081] [Citation(s) in RCA: 43] [Impact Index Per Article: 3.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/12/2013] [Accepted: 11/21/2013] [Indexed: 01/21/2023] Open
Abstract
Maternal vitamin D deficiency has been suggested to influence fetal and neonatal health. Little is known about vitamin D status in Chinese pregnant women. The purpose of this study was to assess the vitamin D status of pregnant women residing in Beijing in winter and evaluate the impact of maternal factors on serum 25-hydroxyvitamin D [25(OH)D] levels. The study was conducted on 125 healthy pregnant women. For each individual, data concerning pre-pregnancy weight, educational status, use of multivitamins and behavioral factors such as daily duration of computer use, walking and sun exposure were obtained. Serum concentrations of 25(OH)D were measured by enzyme-linked immunosorbent assay. The prevalence of vitamin D deficiency (25(OH)D < 50 nmol/L) was 96.8% and almost half (44.8%) of women were severely vitamin D deficiency (25(OH)D < 25 nmol/L). The concentration of 25(OH)D was lower in women with shorter duration of sun exposure (≤ 0.5 h/day, 25.3 ± 8.9 nmol/L) than that in women with longer duration of sun exposure (> 0.5 h/day; 30.3± 9.5 nmol/L; P = 0.003). Thirty six women (28.8%) had sun exposure duration ≥ 1.5h/day. The 25(OH)D concentration in these women was 31.5 ± 9.4 nmol/L which was also much lower than the normal level. Women who reported taking a multivitamin supplement had significantly higher 25(OH)D concentrations (32.3 ± 9.5 nmol/L) when compared with non-users (24.9 ± 8.2 nmol/L; P < 0.001). Pregnant women in Beijing are at very high risk of vitamin D deficiency in winter. Duration of Sun exposure and the use of multivitamin were the most important determinants for vitamin D status. However, neither prolonging the time of sunlight exposure nor multivitamin supplements can effectively prevent pregnant women from vitamin D deficiency. Other measures might have to be taken for pregnant women to improve their vitamin D status in winter.
