非体育学部系男子大学生のサプリメントの利用実態と食に関する保健行動

非体育学部系大学に在籍する男子大学生160人を対象として2002年10月に(1)サプリメントの利用状況、(2)食生活状況、(3)健康に関する行動についてアンケート調査を実施した。"スポーツサプリメント"を利用している者は47%、"スポーサツプリメント以外の一般的なサプリメント"を利用している者は18%であり、いずれのサプリメントも週2回以上利用している者が約50%であった。"スポーツサプリメント"は友人・コーチの勧めで、"一般サプリメント"は家族の勧めで利用されていた。また、"スポーツサプリメント"利用群は、非利用群と比較して食事を欠食しない傾向にあり(p<0.05)、体調がよいとした者が多く(p<0.05)、運動を実施している者も多かった(p<0.05)。しかしながら、運動の頻度・継続時間に有意な差は認められなかった。一方、"一般サプリメント"利用群は、非利用群と比較して夕食を一人で食べる傾向にあった(p<0.05)。なお、エステティックサロンの利用意欲、ファッション雑誌の購読状況には"スポーツサプリメント"でも"一般サプリメント"でも、それぞれのサプリメントの利用群と非利用群の間に有意な差は認められなかった。""We carried out a questionnaire survey to clarify the association between the use of dietary supplements and health-related behaviors in male students of Non-athletic College. Of the subjects, 47% had used dietary supplements for sporting activity while 18% had used dietary supplements for disease prevention. About 50% of these users were using these supplements twice or moreweek. Supplements for sport were used on the recommendation of friends and coaches while supplements for disease prevention were consumed on the recommendation of family members. Health-related behaviors differed between the groups using or not using supplements. The group using supplements for sport less frequently skipped meals (p<0.05), more frequently were in good physical condition (p<0.05) and higher proportion of peoples who have a habit of exercise (p<0.05) than the group not using supplements for sport. However, no significant difference was observed in the frequency and time spent exercising between the two groups. The group using supplements for disease prevention more frequently had supper alone than the group not using supplements for disease prevention (p<0.05). No significant difference was observed in the will to visit aesthetic salons or the state of subscription of fashion magazines between the groups using and not using supplements for sport, or between the groups using and not using supplements for disease prevention.原著Original国立情報学研究所で電子

Changes in total body bone mineral density following a common bone health plan with two versions of a unique bone health supplement: a comparative effectiveness research study

<p>Abstract</p> <p>Background</p> <p>The US Surgeon General's Report on Bone Health suggests America's bone-health is in jeopardy and issued a "call to action" to develop bone-health plans that: (1) improve nutrition, (2) increase health literacy and, (3) increase physical activity. This study is a response to this call to action.</p> <p>Methods</p> <p>After signing an informed consent, 158 adults agreed to follow an open-label bone-health plan for six months after taking a DXA test of bone density, a 43-chemistry blood test panel and a quality of life inventory (AlgaeCal 1). Two weeks after the last subject completed, a second group of 58 was enrolled and followed the identical plan, but with a different bone-health supplement (AlgaeCal 2).</p> <p>Results</p> <p>There were no significant differences between the two groups in baseline bone mineral density (BMD) or in variables related to BMD (age, sex, weight, percent body fat, fat mass, or fat-free mass). In both groups, no significant differences in BMD or related variables were found between volunteers and non-volunteers or between those who completed per protocol and those who were lost to attrition.</p> <p>Both groups experienced a significant positive mean annualized percent change (MAPC) in BMD compared to expectation [AlgaeCal 1: 1.15%, <it>p </it>= 0.001; AlgaeCal 2: 2.79%, <it>p </it>= 0.001]. Both groups experienced a positive MAPC compared to baseline, but only AlgaeCal 2 experienced a significant change [AlgaeCal 1: 0.48%, <it>p </it>= 0.14; AlgaeCal 2: 2.18%, <it>p </it>< 0.001]. The MAPC in AlgaeCal 2 was significantly greater than that in AlgaeCal 1 (<it>p </it>= 0.005). The MAPC contrast between compliant and partially compliant subjects was significant for both plans (<it>p </it>= 0.001 and <it>p </it>= 0.003 respectively). No clinically significant changes in a 43-panel blood chemistry test were found nor were there any changes in self-reported quality of life in either group.</p> <p>Conclusions</p> <p>Following The Plan for six months with either version of the bone health supplement was associated with significant increases in BMD as compared to expected and, in AlgaeCal 2, the increase from baseline was significantly greater than the increase from baseline in AlgaeCal 1. Increased compliance was associated with greater increases in BMD in both groups. No adverse effects were reported in either group.</p> <p>Trial Registration</p> <p>ClinicalTrials.gov <a href="http://www.clinicaltrials.gov/ct2/show/NCT01114685">NCT01114685</a></p

Local Foods Can Increase Adequacy of Nutrients Other than Iron in Young Urban Egyptian Women: Results from Diet Modeling Analyses

BACKGROUND: Nutrition transition and recent changes in lifestyle in Middle Eastern countries have resulted in the double burden of malnutrition. In Egypt, 88% of urban women are overweight or obese and 50% are iron deficient. Their energy, sugar, and sodium intakes are excessive, while intakes of iron, vitamin D, and folate are insufficient. OBJECTIVE: This study aimed to formulate dietary advice based on locally consumed and affordable foods and determine the need for fortified products to meet the nutrient requirements of urban Egyptian women. METHODS: Food intakes were assessed using a 4-d food diary collected from 130 urban Egyptian women aged 19-30 y. Food prices were collected from modern and traditional markets to calculate diet cost. Population-based linear and goal programming analyses (Optifood tool) were used to identify "limiting nutrients" and to assess whether locally consumed foods (i.e., consumed by >5% of women) could theoretically improve nutrient adequacy at an affordable cost (i.e., less than or equal to the mean diet cost), while meeting recommendations for SFAs, sugars, and sodium. The potential of hypothetical fortified foods for improving intakes of micronutrients was also assessed. RESULTS: Iron was the most limiting nutrient. Daily consumption of fruits, vegetables, milk or yogurt, meat/fish/eggs, and tahini (sesame paste) were likely to improve nutrient adequacy for 11 out of 12 micronutrients modeled. Among fortified foods tested, iron-fortified rice, milk, water, bread, or yogurt increased the minimized iron content of the modeled diet from 40% to >60% of the iron recommendation. CONCLUSIONS: A set of dietary advice based on locally consumed foods, if put into practice, can theoretically meet requirements for most nutrients, except for iron for which adequacy is harder to achieve without fortified products. The acceptability of the dietary changes modeled needs evaluation before promoting them to young Egyptian women
