Prevalence Of Dietary Supplement Use Research Articles

Knowledge Concerning Dietary Supplements among General Public.

Introduction. Diet and physical activity are widely recognized in maintaining health and preventing diseases. Currently, dietary supplements are also commonly believed to play a role in health promotion. However, a dietary supplement lacks single uniform definition within the scope of legal or nutritional sciences. Data on the usage of dietary supplements in Europe are still limited. The aim of this study was to assess subjective and objective knowledge of the inhabitants of south-eastern Poland about diet and supplementation in sport. Materials and Methods. The research was conducted in the south-east of Poland between October 2017 and July 2018 during three events organized by the University of Rzeszów. Initially, the study covered 500 people. During the preliminary analysis, 90 people were excluded from the study because they did not meet the previously well-explained rules of conduct during the study or did not meet the eligibility criteria for the tests. Finally, 410 people were qualified for the study. The survey method was a questionnaire with single-answer option. Results. Our study revealed statistically significant subjective and objective level of knowledge about diet and supplementation in terms of sex. Also, a correlation was found between sex and the fact of being involved in physical activity, as well as the subjects' knowledge of diet and supplementation in sport. Conclusion. High prevalence of dietary supplement use was found in our study population, but still significant percentage of the study group demonstrate inaccurate information about these products. Hence, there is an urgent need to provide the community with education and access to scientific and unbiased information.

Dietary Supplement Use Among Adult Cancer Survivors in the United States

Background: Many cancer survivors initiated dietary supplement use after cancer diagnosis, and some may use supplements at high doses without consulting their healthcare providers. Methods: We evaluated the prevalence, dose, and reason of dietary supplement use among 3988 adult cancer survivors in the National Health and Nutrition Examination Survey (NHANES) 1999-2014 and compared that to 7770 individuals without a history of cancer who were matched cancer survivors by age, sex, and race/ethnicity. Findings: Compared to individuals without cancer, cancer survivors reported a higher prevalence of any dietary supplement use (69·9% vs. 63·4%), multivitamin/mineral supplement use (51·1% vs. 46·4%), and individual supplement use for each of the 26 vitamins and minerals being examined. Cancer survivors did not differ from non-cancer individuals for nutrient intake from foods but had higher levels of nutrient intake for five vitamins (vitamin A, retinol, vitamin D, niacin, folate) and five minerals (calcium, selenium, magnesium, zinc, and copper) from supplements than non-cancer individuals. While supplement use contributed to a lower percentage of cancer survivors with inadequate intake (< Estimated Average Requirement) for vitamins C, D, and E, it also increased the percentage of cancer survivors with excess intake (≥Tolerable Upper Intake Levels) for vitamin D, folate, vitamin B6, niacin, and selenium. Nearly half (48·5%) of the cancer survivors used dietary supplements on their own without consulting healthcare providers. Interpretation: Cancer survivors reported a higher prevalence and dose of dietary supplement use than the general population. The short-term and long-term health impact of dietary supplement use, especially high doses of supplement use among cancer survivors needs to be evaluated. Funding: This study was supported by NIH/ NIMHD 1R01MD011501 (FFZ). Declaration of Interest: The authors have no conflicts of interests to disclose. Ethical Approval: The NHANES study procedures were approved by the research ethics review board of NCHS.

Association Between Dietary Supplement Use and ICD-9-CM Code Classification in Active Duty US Navy and Marine Corps Service Members.

This study is the first to our knowledge to examine associations of survey-reported dietary supplement use with medical record diagnoses, rather than retrospective self-reported supplement use at the time of the medical encounter or case reports of adverse events. Dietary supplement (DS) use and adverse events associations in US Navy and Marine Corps personnel remains unknown. This study assessed associations of DS use in active duty (AD) personnel with ICD-9-CM diagnostic codes from outpatient medical encounters from the Military Health System Data Repository (MDR). This cross-sectional investigation used a one-time survey of DS use among AD conducted August through December 2014. Survey data were matched to MDR data accessed in September 2016, and associations between the survey responses and diagnoses were analyzed. Statistical significance was set at alpha level 0.005, and 99.5% confidence intervals (CIs) were calculated. MDR data were matched with survey results for 1,708 personnel. Multivariable logistic regression analyses examined whether use of specific classes of supplements was associated with disease. Results revealed significant associations between vitamin supplement use and ICD-9-CM-diagnosed diseases of the nervous system (odds ratio [OR]: 1.72, 99.5% CI: 1.11-2.68) and diseases of the musculoskeletal system and connective tissue (OR: 1.59, 99.5% CI: 1.17-2.17). Joint health supplement category use was associated with diseases of the musculoskeletal system and connective tissue (OR: 1.81, 99.5% CI: 1.12-2.94) and injury and poisoning (OR: 1.82, 99.5% CI: 1.10-3.04). The percentages of service members with diseases in specific ICD-9-CM diagnostic categories were similar to those reported in other studies using military medical data. There is a greater prevalence of dietary supplement use by the service members who participated in this survey compared with the general population, with 73% of US Navy and Marine Corps personnel reporting use of dietary supplements one or more times per week compared to the estimated 50% of all Americans currently using some form of dietary supplement. The DoD ensures the optimal readiness, performance, and health of its military service members, thus future longitudinal evaluation of dietary supplement use by this population will test the preliminary findings of this study.

Diagnoses associated with dietary supplement use in a national dataset

ObjectivesThe purpose of this study was to determine if participant diagnosis, as determined by a health care provider, is associated with dietary supplement (DS) use. Design/settingSurveys from 1255 study participants aged 34–84, part of the Midlife in the US Study (MIDUS 2 Survey) Biomarker Project, were reviewed. Participant data included pharmaceutical use (prescription and over-the-counter medications (OTC)), clinical symptoms and diagnosis, and laboratory results. Associations were calculated between the above participant characteristics and DS use. Main outcome measuresFrequency of DS use for physician-reported diagnoses. ResultsOverall prevalence of DS use was 32.4%. Participants taking DS were more often female (p = .048), white (p < 0.001), and older (mean age 57 years, p < 0.001). Participants taking DS reported taking more OTC (p < .001) and prescription medications (p = .024), and had an increased number of chronic conditions (p = .004). Participants reporting physician-diagnosed diabetes were significantly less likely to be taking DS (p = .0066), while participants with eye disease (p = .001), high cholesterol (p = 0.041), cancer (p = 0.042), and arthritis (p = 0.044) were more likely to be taking DS than those without those conditions. No difference in DS use was found between patients with and without other identified medical conditions. After adjusting for age, race/ethnicity, and gender, only diabetes remained a significant predictor of decreased DS use (OR 0.588, CI 0.388-0.873, p = .01). ConclusionsSome physician-reported participant diagnoses were associated, positively or negatively, with DS use.

Dietary Supplement Use among Infants and Toddlers Aged

Limited nationally representative data are available on dietary supplement (DS) use and resulting nutrient exposures among infants and toddlers. This study evaluated DS use among US infants and toddlers to characterize DS use, estimate nutrient intake from DSs, and assess trends in DS use over time. Using nationally representative data from NHANES (2007-2014) and trends over time (1999-2014), we estimated prevalence of DS use and types of products used for US infants and toddlers aged <2 y (n=2823). We estimated median daily intakes of vitamins and minerals consumed via DSs for all participants aged <2 y, by age groups (0-11.9 mo and 12.0-23.9 mo), and by feeding practices for infants 0-5.9 mo. Overall, 18.2% (95% CI: 16.2%, 20.3%) of infants and toddlers used ≥1 DS in the past 30 d. Use was lower among infants (0-5.9 mo: 14.6%; 95% CI: 11.5%, 18.1%; 6-11.9 mo: 11.6%; 95% CI: 8.8%, 15.0%) than among toddlers (12-23.9 mo: 23.3%; 95% CI: 20.4%, 26.3%). The most commonly reported DSs were vitamin D and multivitamin infant drops for those <12 mo, and chewable multivitamin products for toddlers (12-23.9 mo). The nutrients most frequently consumed from DSs were vitamins D, A, C, and E for those <2 y; for infants <6 mo, a higher percentage of those fed breast milk than those fed formula consumed these nutrients via DSs. DS use remained steady for infants (6-11.9 mo) and toddlers from 1999-2002 to 2011-2014, but increased from 7% to 20% for infants aged 0-5.9 mo. One in 5 infants and toddlers aged <2 y use ≥1 DS. Future studies should examine total nutrient intake from foods, beverages, and DSs to evaluate nutrient adequacy overall and by nutrient source.

Dietary Supplement Use Among Chinese Primary School Students: A Cross-Sectional Study in Hunan Province

Dietary supplement use is increasing globally, especially among children. However, few studies have been conducted to examine dietary supplement use among Chinese children. The aim of this study was to examine the prevalence of dietary supplement use and the associated factors in primary school students. A cross-sectional study was conducted in four primary schools in Hunan province, China. A total of 706 Chinese parents/caregivers of school children aged 6–12 years old were enrolled. Self-administrated questionnaires were used to collect information about the children’s dietary supplement use, and their socio-demographic characteristics. The prevalence of dietary supplement use in primary school students was 20.4%. Calcium (16.7%), vitamin C (9.2%), and vitamin D (8.5%) were the most commonly used types of dietary supplement. The main reasons for parents/caregivers to purchase dietary supplements for their children were immunity improvement (43.6%), and for growth promotion (36.5%). Some caregivers (26.4%) purchased dietary supplements online, including from dubious or unknown sellers. However, 37.5% of caregivers did not receive formal guidance on supplementation even if they purchased their supplements through formal channels. Parents/caregivers were unclear about the appropriate choices for children’s dietary supplement use. Guidelines and counseling regarding dietary supplements for children may be helpful in public health work.

Prevalence and patterns of dietary supplement use in elite Spanish athletes

BackgroundDietary supplementation is a common strategy to achieve a specific health status or performance benefit. Several investigations have focused on the prevalence of dietary supplement use by athletes. However, information on how athletes manage the use and purchase of dietary supplements is scarce.MethodsFive hundred and twenty-seven high-performance athletes (346 males and 181 females), participating in individual and team sports, completed a validated questionnaire about use and purchase patterns of dietary supplements. The dietary supplements were categorized according to the International Olympic Committee (IOC) consensus.ResultsSixty four percent of the athletes (n = 337) used dietary supplements (median = 3; range 1 to 12). Age, sex, type of sport, level of competition, and professionalism influenced the prevalence of dietary supplement use (all p < 0.05). The most prevalent dietary supplement consumed was proteins (41%; n = 137), followed by amino acids/BCAA-based supplements (37%; n = 124). Additionally, as per group of supplements according to IOC consensus, 18% of the supplements were rated as having a low level of scientific evidence (e.g., glutamine, HMB, L-carnitine, etc). Most athletes (45%, n = 152) purchased dietary supplements in a store and 24% (n = 81) obtained them from a sponsor. Most athletes also (42%, n = 141) reported a self-organization of supplementation and did not consult with any professional. Last, 81% (n = 273) of athletes consuming supplements did not know any platform to check supplement safety/quality. For those who do not use dietary supplements (36% of the total sample, n = 190), most reported that they do not consider supplements necessary (72%, n = 137).ConclusionDietary supplementation appears to be widely used in sport with a considerable proportion of athletes consuming supplements with low level of scientific evidence. Additionally, athletes seem to rely on inadequate sources of information and may be largely unaware of sources to detect supplement contamination.

Dietary supplements: a great menace of our time or golden remedy? A cross-sectional study amongschool-aged children.

IntroductionDietary supplements (DS) are commonly used as a remedy for various health issues as they are widely advertised and available.AimThis study aimed to evaluate the prevalence of DS use among school-aged children in Warsaw, the capital city of Poland. Additionally, we evaluated the parents’ motivations for DS administration, the frequency of the use of specific compounds and the influence of child’s history of allergy on DS use.Material and methodsChildren aged 6–7 years who attended the first grade of primary schools in Warsaw were included into the study. Forty-two out of 170 primary schools in Warsaw were randomly selected of which 38 agreed to participate. The research tool was a self-administered questionnaire.ResultsHalf of the studied children received DS in the previous 6 months. Fatty acids were the most commonly administered DS (49.8%). The most common reason for administering DS was prevention of diseases (69.1%). The total household income correlated positively with the DS use. History of food allergy was one of the factors which increased the risk of DS use, whereas diagnosis of asthma did not correlate with a higher frequency of DS use.ConclusionsThis study shows the need to educate patients about medical indications for DS use and expected benefits in the specific indications.

Antioxidant supplementation and breast cancer prognosis in postmenopausal women undergoing chemotherapy and radiation therapy

There is a paucity of information on the prevalence of dietary supplement use in breast cancer survivors. Only a few studies have examined the impact of dietary supplements, particularly antioxidants, on breast cancer prognosis and the results are inconclusive. We examined pre- and postdiagnosis use of supplements in postmenopausal breast cancer survivors in Germany and investigated associations between postdiagnosis use of antioxidants and other supplements, and prognosis (total and breast cancer mortality, and recurrence-free survival) both overall and in women who received chemotherapy and radiation therapy. Data from 2223 postmenopausal women diagnosed with nonmetastatic breast cancer from the population-based Mamma Carcinoma Risk Factor Investigation (MARIE) study were used. Women were interviewed at recruitment in 2002-2005 and again in 2009 and followed-up until 30 June 2015. Multivariate Cox regression analysis was used to estimate HRs and corresponding 95% CIs. Pre- and postdiagnosis supplement use was reported by 36% and 45% of the women, respectively. There were 240 deaths (134 from breast cancer) and 200 breast cancer recurrences after a median follow-up time of 6.0 y after the 2009 re-interview. After adjusting for relevant confounders, concurrent antioxidant use with chemotherapy or radiation therapy among 1940 women was associated with increased risk of total mortality (HR: 1.64; 95% CI: 1.01, 2.66) and worsened recurrence-free survival (HR: 1.84; 95% CI: 1.26, 2.68). Overall postdiagnosis supplement use was not associated with breast cancer prognosis. Antioxidant use during chemotherapy or radiation therapy was associated with worsened breast cancer prognosis in postmenopausal women. There was no overall association between postdiagnosis supplement use and breast cancer prognosis. Results from our study align with the current recommendation to possibly avoid the use of antioxidants during chemotherapy or radiation therapy.

Dietary supplement use among undergraduate male students in health and non-health cluster colleges of a public-sector university in Dammam, Saudi Arabia

BackgroundDietary supplements (DS) are nutraceuticals that improve overall health and well-being of an individual as well as reduce the risk of diseases. Evidence indicates a rising prevalence of these products worldwide especially among college students. Studies have reported an increasing use of supplements among Saudi students. However, the scope of those researches was limited to prevalence data. Hence, the aim of our study was to document the prevalence, opinions, attitudes, reasons for use and monthly cost attributed to dietary supplement use.MethodsA 3-month cross-sectional study was conducted to evaluate use of dietary supplement among health and non-health college students at a public-sector university in Dammam city, Saudi Arabia. It was conducted using Arabic version of the Dietary supplement questionnaire (DSQ-A). A total of 469 male students responded to the survey giving a response rate of 93.8%. The students were from ten colleges of the university. The data was analyzed by SPSS version 22. The study was approved by Institutional Review Board of Imam Abdulrahman Bin Faisal University, Dammam, Saudi Arabia (IRB-UGS-2018-05-074).ResultsThe overall prevalence of dietary supplement use in the university was 29.42%. In health cluster colleges, it was reported at 35.91% while in non-health cluster college it was 23.69%. Maintaining general health and well-being was the most common reason for use. Prevalence of multivitamins and whey proteins was approximately 23%. Average monthly cost of supplement was SAR 278.92 (USD 74.39). Cost was positively correlated (ρ = 0.305) with satisfaction score. Students preferred brand products (16.4%). 41.4% students opined that DS may prevent chronic illness if used regularly and agreed that they are good for health. Majority of students (65%) recommended DS use only upon physician’s recommendation. College clusters and study-year was associated (p-value< 0.01) with students’ opinion. Students in health cluster colleges were more likely to recommend supplements (OR 3.715, p-value< 0.0001).ConclusionPrevalence of dietary supplement use was lower than other local and international university students. Health cluster colleges had higher prevalence as compared to non-health cluster colleges. Multivitamins and whey protein were the most commonly used types of DS. Students preferred brand products, had positive opinions and attitudes towards dietary supplement. However, they recommended supplements use to others only upon a physician’s recommendation.

The Prevalence of Dietary Supplement Use Among Elementary, Junior High, and High School Students: A Nationwide Survey in Japan.

The prevalence of dietary supplement use, such as vitamins, minerals, or fish oil, has increased among children in Japan; however, whether children are using dietary supplements appropriately remains unclear. This study aimed to determine dietary supplement use among children. In August 2017, a nationwide internet preliminary survey of 265,629 mothers aged from 25 to 59 years old was undertaken. Of these, 19,041 mothers of children attending either elementary school, junior high school, or high school were selected. Among them, 16.4% were currently providing their children with dietary supplements and 5.2% had previously given dietary supplements to their children. The prevalence of dietary supplement use was higher in boys than in girls, and the prevalence increased according to their grade. A total of 2439 participants were eligible to undertake a targeted survey on dietary supplement use. Dietary supplements were being taken to maintain health, supplement nutrients, and enhance growth in both boys and girls, and many children (37.5%) were provided with vitamin and mineral supplements. Mothers mainly obtained information concerning dietary supplements via the internet, and supplements were purchased in drug stores or via the internet. The prevalence of dietary supplement use in mothers was 65.4% and may be associated with the prevalence rates in children. Some mothers reported adverse events (3.6%) in their children, such as stomachache, diarrhea, nausea and vomiting, and constipation. The cause-and-effect relationships for adverse events were not clear, but some children were given products for adults. Children are more influenced by dietary supplements compared to adults. To prevent adverse events due to inappropriate use, parental education concerning dietary supplements is essential.

Prevalence of Dietary Supplement Use in US Children and Adolescents, 2003-2014

This study uses NHANES data to estimate the prevalence of dietary supplement use, including both nutritional products and alternative medicines, among US children and adolescents between 2003 and 2014.

Prevalence, Knowledge and Attitudes Concerning Dietary Supplements among a Student Population in Croatia.

The aim of this study was to determine the prevalence of usage and the knowledge and attitudes towards dietary supplements among medical sciences and nonmedical sciences students from Croatia. The study was conducted based on a questionnaire about dietary supplement usage, knowledge and attitudes. The prevalence of dietary supplement use, among 910 university students was 30.5%. The most-used dietary supplements were vitamins (18.0% in medical sciences students and 9.8% in non-medical sciences students). For all students, the internet (66.1%) was the most common source of information, followed by healthcare professionals (33.2%). The most common reason for taking dietary supplements was to maintain good health (26.4%). Use of the internet rather than health professionals as a trusted information source should be revised among this young population. Supplement intake was significantly associated with body mass index (BMI) (p = 0.016) and physical activity (p = 0.050). Students with normal BMI (61.5%) and the most physically active students (37.7%) took significantly more dietary supplements. Results of this study could help medicine faculties to improve their curriculum and support the development of public health messages aimed at wise and safe use of dietary supplements.

Dietary Supplement Use Among Students of Pharmacy Colleges in the City of Karachi, Pakistan: Prevalence, Opinions, and Attitudes

ABSTRACTThis study was conducted among pharmacy students in Karachi, Pakistan, to document prevalence, opinions and their attitudes toward dietary supplement (DS) use. A cross-sectional study was conducted for a period of four months. The study used a specially formulated dietary supplement questionnaire (DSQ). The prevalence of DS use was reported at 48.2%: 51% in males and 47.3% in females. Physician recommendation was cited by majority of students as reason for DS use (n = 153, 25%). Most of the students used multivitamins (n = 315, 51.5%). The average monthly cost attributed to DS use was reported at PKR 1,396.3 (USD 13.55). For every year increase in age, DS use in students decreased (OR = 0.917). Male students were more likely to recommend DS use (OR = 1.425). The most noteworthy finding was the cautious approach of students as the majority reported DS use only upon recommendation of a physician.

Analysis of Safety Alerts Associated with Dietary Supplements from Japan and Overseas

The prevalence of dietary supplement use has increased in Japan, and consumers can purchase supplements from foreign countries through the internet. Therefore, it is important to consider both domestic and overseas safety alerts to prevent adverse events associated with dietary supplement use. We have been collecting global safety alerts associated with dietary supplements and providing this information to the public via the "Information system on safety and effectiveness for health foods (HFNet)" website. In this study, we analyzed the characteristics of safety alerts from 2010 to 2016 in HFNet (total: 2,124 alerts). The most common reason for alerts was illegal adulteration with pharmaceutical substances (85%), and sexual enhancement or weight loss products accounted for 68% of all alerts. Most alerts were based on market surveillance reports or recall information. However, 181 adverse event reports were identified, and most of them were related to weight loss or disease treatment in patients. In Japan, a majority of the adverse events was caused by products intended for weight loss or purchased online, and young female users were commonly involved. These findings should be helpful for prevention of adverse events associated with dietary supplement use.

Prevalence of dietary supplement use and associated factors among female college students in Saudi Arabia

BackgroundThe economic boom in Saudi Arabia indirectly prompted the use of dietary supplements in the last two decades. Our aim is to investigate the prevalence of dietary supplement use and its association with sociodemographic/lifestyle characteristics among Saudi female students.MethodsIn this cross-sectional study, 534 female participants (≥19 years of age) completed a self-administered questionnaire that include sociodemographic and lifestyle characteristics, perceived health status, dietary supplement use, general awareness, attitudes and behavior.ResultsIn all participants, the prevalence of dietary supplement use was 76.6% (n = 409). High level of education (p = 0.002) and more physical activity (p = 0.008) exhibited a significant positive association with users than to non-users. The frequency showed that beta-carotene (54.2%), chamomile (54.2%), and glucosamine (53.8%) were the most preferred diet supplements under the category “when needed”. Cod liver oil (71.3%), omega 3 (68.3%), multi-vitamins (61.5%), ginseng (60%), and vitamin A (60%), were mostly used “from time to time”. Multi-minerals (34.4%) were the preferred choice when it comes to daily use. The main reasons for supplement use were to “maintain healthy hair” and “injury and illness” (both 26.2%). About 38.4% were not aware and 30.3% disagree on differences taking supplements with or without consulting a medical professional. About 36.7% lack information about side effects while, 35.0% were unaware about any health effect of dietary supplements.ConclusionThe prevalence of dietary supplement use was high in Saudi female students and was significantly associated with sociodemographic and lifestyle factors.

Prevalence of Intake of Dietary Supplements in the Population of Saudi Arabia, Jeddah

Background: Several studies have shown micro-nutrient deficiencies in the Middle East region. Prominent defects in vitamin D, folate, and iron were especially noted. There are not many studies currently that tell us about the prevalence of dietary supplement intake in Saudi Arabia. Aim: The aim was to observe the current prevalence of dietary supplement use in Saudi Arabia. We will also attempt to elicit the reason they take the supplements, and how it affects their overall quality of life. Method: Cross-sectional study among 489 Saudi patients was without any exclusion criteria using a standard questionnaire. The study was held at the endocrinology department of King Abdul Aziz Hospital & Oncology Center in Jeddah, Saudi Arabia. Results: The overall prevalence of multivitamin, mineral and supplement intake in the Saudi population was found to be 22%. Among them 16% were male and 24% were female. Conclusion: Healthcare providers must spread more awareness about the potential benefits of dietary supplements in preventing non-communicable diseases.

Faster, Stronger, Healthier: Adolescent-Stated Reasons for Dietary Supplementation

ObjectiveExamine the underlying reasons and sources of recommendation for dietary supplement (DS) use among adolescents. DesignCross-sectional analysis of children's development in Slovenia in September to October, 2014. SettingNationally recruited sample. ParticipantsAdolescents aged 14–19 years enrolled in 15 high schools (n = 1,463). Variables MeasuredReasons for and sources of recommendation for DS use, sports club membership, sports discipline, and extent of physical activity (PA) were self-reported data. AnalysisChi-square test of independence was performed to compare the prevalence of DS use between groups with different extents of PA and nonathletes/athletes, referring to 11 different reasons and 9 different sources of recommendation for DS use. ResultsUse of DS was widespread among adolescents (69%), athletes (76%), and nonathletes (66%). Higher prevalence of supplementation was observed in males, who justified it use for sports performance enhancement and better development and function of muscles. In contrast, females emphasized immune system improvement. Higher extent of PA was associated with a higher prevalence of DS use. This was especially evident in males, who participated in team sports. A high percentage of adolescents (41%) decided on their own to use DS and because of advice from parents or relatives (30%). Conclusions and ImplicationsSeveral reasons for the widespread use of DS in adolescents were associated with sports participation. Therefore, educational programs regarding DS use should be targeted primarily to adolescents and their parents who are involved in sports, and especially team sports.

Factors associated with dietary supplement use in Saudi pregnant women

BackgroundThe aim was to investigate the prevalence of dietary supplement use among pregnant Saudi women and its associations between various demographics.MethodsIn 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.ResultsDietary 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).ConclusionsThis 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.

Micronutrient Intake and the Contribution of Dietary Supplements in Hispanic Infants

ABSTRACTTo calculate micronutrient adequacy among infants and toddlers and to determine the contribution of dietary supplements to this adequacy, micronutrient intake was assessed using two nonconsecutive 24-hour recalls in a sample of 296 infants aged 0–24 months. Micronutrient intake was calculated from foods and beverages and from supplements and compared between nonusers and users of supplements. Percentages of children below the Dietary Reference Intake (DRI) and above the tolerable upper limit intake (UL) were also compared between groups. A total of 241 participants had complete data. The prevalence of dietary supplement use among the sample was 15%. Mean intake of all micronutrients from foods and beverages was similar between nonusers and users of supplements (p > .05) but significantly higher for the following vitamins when supplements were included: D, E, B1, B2, B3, and B6 (p < .05). From foods only, the nutrients with highest percentage of children below the DRI were vitamins D and E and potassium. When supplements were included, this percentage significantly decreased among users compared to nonusers (p < .05) for vitamins D and E. From foods, the UL was exceeded for magnesium, zinc, and vitamin B3. These were similar when supplements were added. Supplements significantly increased the intake of some vitamins. Vitamins D and E had the highest percentage of children below the DRI, which was partly corrected with the use of supplements. The UL was exceeded for magnesium, zinc, and vitamin B3 in many children. It is important to understand these patterns as they may be indicative of future nutritional deficiencies and excesses.
