Daily intake of green and yellow vegetables is effective for maintaining bone mass in young women.
ABSTRACT The increasing proportion of underweight young women may lead to an increase in those with low bone mass. The present study investigated whether bone mass level is associated with lifestyle factors among young Japanese women. A total of 103 Japanese female college students aged 20-21 majoring in food science participated in this cross-sectional study. We measured bone area ratio at the os calcis using quantitative ultrasound (QUS) and assessed lifestyle factors including diet and physical activity using a self-reported questionnaire. Bone area ratio was defined as a proportion of bone substance in a cross section of os trabeculare. Ninety-one subjects who completed the questionnaire were categorized into two groups according to the average bone area ratio of the 103 subjects (30.9%), calculated based on the screening method for osteoporosis prevention: 69 subjects with normal bone mass (bone area ratio: 36.2 +/- 3.8%) and 22 subjects with low bone mass (bone area ratio: 28.1 +/- 1.6%). In normal group, 12 subjects (17.4%) had a dietary habit of not daily intake of green and yellow vegetables, such as carrot and spinach, while this occurred in 10 subjects (45.5%) in low group (P = 0.007). Adjusted logistic regression analyses showed that the subjects without daily intake of green and yellow vegetables had almost 5-fold risk of low bone mass, compared to the subjects having daily intake of the vegetables [Odds ratio: 4.96 (95%CI 1.36-18.18)]. In conclusion, daily intake of green and yellow vegetables is effective for maintaining bone mass in young women.

ABSTRACT: Background: Osteoporosis-related fragility fracture is a major health issue in older adults. This study has been developed to investigate the relationship of lifestyle factors with fragility fracture prevalence in postmenopausal Taiwanese women. Methods: A total of 1050 postmenopausal women with a mean age of 66.7 AE 8.6 years who lived in the community in western Chiayi County in Taiwan was interviewed with a structured questionnaire collected personal data, lifestyle information and fracture history. Laboratory examinations provided biochemistry data. Fragility fractures were defined as those resulting from low energy impact. The relationship between fragility fracture prevalence and other variables was analyzed. Results: The overall prevalence of fractures of all etiologies and fragility fracture were 18.7% and 9.7%, respectively. Wrist was the most common site of fragility fracture (48 cases). Fragility fracture prevalence in participants who rarely or did not consume deep-colored vegetables was significantly higher than that of those who often consumed deep-colored vegetables: 17.6% versus 9.0%, with an odds ratio of 1.96 (95% confidence interval: 1.05e3.68) by multivariate logistic regression analysis. Conclusion: Insufficient intake of deep-colored vegetables is associated with increased risk of fragility fracture.International Journal of Gerontology 11/2012; 7(2).

ABSTRACT: Objectives: The purpose of this study was to investigate the knowledge, believes and behaviors regarding osteoporosis risk factors and preventive health habits such as adequate calcium intake and physical activity. Subjects: A sample of 494 girls aged between 16-24 years from Faculty of Education for Specific Studies was recruited in the study. Methods: Information was gathered through across-sectional survey. A self administered questionnaire was distributed among the students to collect data about osteoporosis knowledge physical activity and calcium intake. Results: Four hundred and thirty five girls (88.1%) had heard of and (48%) had the correct definition of osteoporosis. The main source of information about osteoporosis was television (34%) followed by mothers & relatives (27.1%). Overall,(22.5%) of girls perceived that they were likely to develop osteoporosis for different reasons. Respondents believed that osteoporosis is more serious (59.6%) than other common causes of morbidity and mortality such as heart disease and breast cancer. More than half of girls were aware of the benefits of exercise in preventing osteoporosis (59.1%), only (42.9%) participate in some sort of sports not on regular basis. Knowledge related to calcium rich food and requirements were poor. Conclusion: In summary, results obtained from this study were used to build on for health education intervention program targeted to this group of girls.

ABSTRACT: Background: Nutrition is one of the most important factors influencing human health. Also, nutrition plays a role in the etiology of osteoporosis disease. This disease is a serious metabolic bone disorder that often results in hip fracture and is usually asymptomatic in its initial stages. Objective: Assess the prevalence of obesity and osteoporosis among university students. Methods: A cross sectional study was carried out during the period from 1/1/2010 to 30/1/2013 among a random sample of 218 male and 257 female university students participate from Umm Al Qura university of Makkah age ranged from 19 to 24 years old. A direct interview was run all students to collect a specially designed bone health related questionnaire, bone mineral density (BMD) sos instrument and body composition have also been measured by using scale body state device. Results: Osteoporosis was present in 2.8% and 7% for male and female respectively, while osteopenia was current in 42.2% and 32.3% of male and female resp. Moreover there was a highly increased positive significant relationship at level (1%) between osteoporosis and each of body fat %, fat weight, and BMI. Conclusion: Osteoporosis more common in female students, while osteopenia is increased in male students. The prevalence of osteoporosis among university students was positively and significantly associated (p<0.001) with increased body fat. The study results suggested that inevitable decrease in body fatness and weight with less consumption of carbonated beverages, taking into consideration variety and balanced diets and increasing nutrition education programs.05/2014; 2(2):29-35.
