Prevalence of nonvitamin, nonmineral supplement usage among undergraduate students at the University of Wisconsin-Stout
Full text linkPlan BThe use of dietary supplements in the United States is increasing due to the growing interest in nutrition. Herbs, amino acids, vitamins, and minerals are all categorized together vaguely as dietary supplements. In the U.S., approximately fifty percent of the population use dietary supplements. Many dietary supplements are showing positive effects, but they have the potential to cause multiple problems if people that use supplements are undereducated or misinformed. Herbal supplements involve more safety concerns than vitamins and minerals, due to the lack of a guarantee that the product has known pharmacological effects. By determining the prevalence of nonvitamin, nonmineral supplementation among undergraduates, professionals can be armed with knowledge to teach about appropriate use and potential side effects that are associated with supplement use. This study was designed to: 1) quantify the prevalence of nonvitamin, nonmineral supplement usage among Unversity of Wisconsin-Stout undergraduate students, 2) identify supplements consumed, 3) identify the rationale for supplement usage, 4) identify the source of supplement information, and 5) relate usage to selected demographic characteristics. The subjects included undergraduate students enrolled in Health and Physical Education general education courses. A total of 486 students participated. There were 210 males and 276 females. Two hundred and twelve subjects (43.6%) reported that they were freshmen and 368 of the respondents (75.8%) were between the ages of 18 and 21. Seventy-four (15.2%) of the participants reported current use of nonvitamin, nonmineral supplements. The students in this sample noted ginseng, creatinine, echinaccea, green tea, and protein powder as the most common supplements used. Findings showed that the most prevalent reason for using supplements among students who used supplements was found to be to improve energy (55.1%). Of the students taking supplements the majority (69.4%) obtained supplement information primarily from family and friends. The recommendations determined from this study was that people who use nonvitmamin, nonmineral supplements should look for side effects on the product label, look for proper dosage, do not believe outrageous claims, and seek the advice of a health care professional to determine if the product is safe
Dietary Supplements

Yet their safety remains questionable and their use is accompanied with risks based on the currently available research data. Stricter regulations of their market must be implemented by competent authorities to protect consumers.LBgyógyszerészangolegységes, osztatla

Nutritional supplements during breastfeeding
Full text linkWomen who are breastfeeding have increased requirements for energy and nutrients. Nutritional requirements for lactation have been the subject of several international reports and are included in general nutrient requirements documents, including those of the USA, Australia, European Union and WHO. Recommendations are made for all pregnant women to take folic acid prior to becoming pregnant and during the first trimester of the pregnancy and iodine supplementation is recommended in Australia and many other countries during pregnancy and lactation. The current WHO/ICCIDD/UNICEF recommendation for daily iodine intake (250 μg for lactating mothers) has been selected to ensure that iodine deficiency does not occur in the postpartum period and that the iodine content of the milk is sufficient for the infant's iodine requirement. While recommendations for nutritional supplements during pregnancy are specific, recommendations are usually less specific for lactation. The aim of this study was to review the use of supplements during lactation and to document the use of nutritional supplements in a cohort of mothers who are breastfeeding in Perth, Western Australia. A literature search was undertaken of reviews published between January 2000 and May 2011 and further analysis was undertaken of supplement usage in the Perth Infant Feeding Survey. In the USA the limited data that is available suggest that supplement use during lactation is dependent on demographic, sociologic, and economic factors and that more women take supplements during pregnancy than during lactation. Data from the NHANES III study show that ethnicity and income predicted iron supplementation during lactation, with 77% of non-Hispanic white women reporting supplement use compared with 41% of non-Hispanic black or Mexican American women. Multivitamin-multimineral use was the most frequently reported dietary supplement (33%). In a cohort study of postpartum mothers in Australia the use of supplements fluctuated between 40% to 30%, with 35% still taking supplements a year after birth. During their pregnancy 78% of mothers took a folic acid supplement and 21% took an iron supplement. Mothers who took supplements were more likely to continue breastfeeding. More studies are needed to document supplement use by lactating mothers in different cultures and countries
A Comparative Analysis of Consumers' Consumption Motives and Perception of Dietary Supplements in Hungary and Jordan
No full textThe thesis studies how Hungarian and Jordanian consumers perceive dietary supplements via different dimensions, and how this is translated into their consumption habits. The examined perception dimensions include consumption habits and motives, brand loyalty, effect of word of mouth, knowledge of potential hazards resulting from dietary supplement consumption and knowledge of regulations. Moreover, the thesis presented how the differences in the commercial regulations of dietary supplements in both countries handled the topic of marketing and legislating dietary supplements. The marketing strategies and distribution of dietary supplements worldwide were also studied to examine discrepancies and how it can lead to exploitation of marketing practices. Overall, The umbrella that this study was carried under is ethical marketing, emphasizing exploitation of marketing practices and urging dietary supplements' manufacturers to carry marketing ethically.BSc/BACommerce and Marketin
A profile of dietary supplement use of elderly in two Wisconsin counties
Full text linkPlan BThe use of alternative therapies in the United States is growing rapidly. (Studdert et al 1998) Herbal and dietary supplements are used by more than fifty percent of the U.S. population. The most commonly used supplements are vitamin and mineral preparations, but a wide variety of other substances, like herbals and metabolites are being used in increasing amounts. (Nesheim 1998) Today, the elderly population is at an all time high. It is estimated that the population of those 65 years and older will double to nearly twenty-five percent of the U.S. population by the year 2030. Greater life expectancy represents our ability as a society to make advances in technology, health care, and delivery of nutrition. The elderly are keeping up with these advances by choosing to use various supplements to inhibit or delay health problems associated with advancing age. (Houston et al 1998) Although many dietary supplements are showing positive effects, they can cause multiple problems if consumers are misinformed or undereducated about these products. By profiling supplement use by the elderly, professionals can be armed with knowledge to teach consumers about potential problems that coincide with use of supplements. The purpose of this study was to profile supplement use of the elderly in two Wisconsin counties to identify practice issues for health care providers. The study sought to: 1) identify the most popular supplements used, 2) determine if supplement practices were healthy, 3) identify unhealthy practices and 4) identify the primary information sources for elderly supplement users.
The sample population was taken from the Nutrition Intervention Program (NIP) in Eau Claire and Dunn counties. A total of 52 subjects were recruited from congregate meal sites and the Meals on Wheels program. The seniors in this sample noted multivitamins, vitamin E, C and calcium as the most common supplements used. Dietary supplement practices were found to be healthy in the population studied, subsequently, no unhealthy practices were identified. A majority of the elderly persons (30) obtained supplement information primarily from physicians. Other popular information sources included friends/relatives and television. Overall, elderly supplement practices were considered healthy. Subjects were using responsible dosages and most were consulting a physician regarding supplements
The investigation and assessment of Nutritional and Traditional Supplement products for content validity, contamination and adulteration
No full textIncludes abstract.Includes bibliographical references.Nutritional supplements are used by competitive and recreational athletes of all ages. As a consequence the supplement industry has grown to meet the increasing demand. The regulation of the supplement industry is unrefined, which increases the risk of the nutritional supplements being contaminated. Contamination may be intentional, where the companies “spike” their products with an ergogenic aid, or unintentional. A consequence of contamination is that an athlete may fail a drug test after ingesting a contaminated supplement or there may be negative health consequences. Without adequate legislation it is difficult to control the industry and reduce the risk of contamination in the supplement. Objectives: To investigate the industry associated with commercially available nutritional and traditional supplements. These are in the five specific areas; (i) to review the regulations and legislations, and labelling and claims associated with nutritional products in the USA, European Union and South Africa, (ii) to assess the labelling and claims information on nutritional supplement products imported into and manufactured or assembled in South Africa, (iii) to assess using a survey questionnaire the container labelling and other sources of information that assist consumers of nutritional products in their purchasing decisions, (iv) to assess traditional commercial supplements for contamination and consistency of trace elements and heavy metals using Inductively Coupled Plasma-Mass Spectrometry, and (v) to assess the content of nutritional commercial supplements for steroids, stimulants and other compounds of interest using Tandem Liquid Chromatography-Mass Spectrometry.Methods: The thesis is divided into 6 Chapters. Chapter 1 describes the background to the problem and Chapter 2 reviews the existing legislation. In Chapter 3 the labelling and claims information on 40 nutritional supplements products are analysed, and the self-administered questionnaire determined what product label and other information influences consumers of nutritional supplements in their purchasing decisions. In Chapter 4 the consistency of trace elements and heavy metals are analysed in selected nutritional supplements using Inductively Coupled Plasma Mass Spectrometry. In Chapter 5 selected nutritional supplements are analysed for steroids, stimulants and other compounds using Tandem Liquid Chromatography Mass Spectrometry. All the data of these sections are summarised in Chapter 6
