RESUMO

Objectives@#This study was conducted to create a 3D printable snack dish model for the elderly with low food or fluid intake along with barriers towards eating. @*Methods@#The decision was made by the hybrid-brainstorming method for creating the 3D model. Experts were assigned based on their professional areas such as clinical nutrition, food hygiene and chemical safety for the creation process. After serial feedback processes, the grape shape was suggested as the final model. After various concept sketching and making clay models, 3D-printing technology was applied to produce a prototype. @*Results@#3D design modeling process was conducted by SolidWorks program. After considering Dietary reference intakes for Koreans (KDRIs) and other survey data, appropriate supplementary water serving volume was decided as 285 mL which meets 30% of Adequate intake. To consider printing output conditions, this model has six grapes in one bunch with a safety lid. The FDM printer and PLA filaments were used for food hygiene and safety. To stimulate cognitive functions and interests of eating, numbers one to six was engraved on the lid of the final 3D model. @*Conclusions@#The newly-developed 3D model was designed to increase intakes of nutrients and water in the elderly with dementia during snack time. Since dementia patients often forget to eat, engraving numbers on the grapes was conducted to stimulate cognitive function related to the swallowing and chewing process. We suggest that investigations on the types of foods or fluids are needed in the developed 3D model snack dish for future studies.

RESUMO

Objectives@#The aim of this study was to investigate dietary intakes and nutritional status among Uganda primary school children from two selected schools in urban and rural areas. @*Methods@#Data were collected from 350 pupils (6-14 years) in Mpigi district, Uganda. All participants were offered a school lunch meal (usually maize porridge and boiled beans). Dietary survey was conducted in October 2016. Data for dietary intake levels were collected by the 24-hour recall method with trained school staffs. The data were converted into nutrient intakes using the CAN-Pro 5.0 Program and compared with KDRIs to evaluate the nutritional status of the subjects. Diet quality indexes such as nutrient density, nutrient adequacy ratio (NAR), mean adequacy ratio (MAR), and index of nutritional quality (INQ) and a diet diversity index such as diet diversity score (DDS) were calculated to evaluate nutritional status among subjects. Data were analyzed using SPSS statistical programs. @*Results@#Results show that the intakes of most nutrients were significantly different by schools. The nutritional status of micro-nutrients was very low in both schools according to analysis of nutritional indexes such as NARs and INQs. Students from both schools should improve intakes of micro-nutrients related to child growth such as calcium, Vitamin B6, zinc and folate. According to the analysis of dietary diversity, there was difference in dietary patterns by schools presumably due to their locations. @*Conclusions@#This suggests that current meals could not provide adequate nutrients for the subjects and urgent nutrition interventions for school food services are needed to improve their nutritional well-being. New foods supplements based on local cuisine are also needed to ensure dietary diversity and sustainable development plans.

RESUMO

BACKGROUND/OBJECTIVES: The leaves of Moringa oleifera (MO) and Moringa stenopetala (MS) commonly grown in Ethiopia possess potential nutritional and medicinal value. The aim of this study was to evaluate the nutritional and functional characteristics of the dried leaf powder from two Moringa species to develop sustainable nutritional supplements for Ethiopians from locally grown plant sources. SUBJECTS/METHODS: Freshly harvested and air-dried MO and MS leaves were authenticated and the nutritional contents, such as protein, ash, lipids, and selected vitamins and minerals, were analyzed using standard analytical procedures. Amino acid compositions were also determined by an amino acid analyzer. Nine-week-old mice were randomly divided into four groups to investigate the anti-obesity effects of Moringa. The first group was fed a basal diet, the second group a high-fat diet, and the others were fed a high-fat diet containing 0.1% Moringa leaf powder from each species. After seven weeks, serum indices related to lipid profiles from each mouse were analyzed. RESULTS: The present study revealed high protein (28–29%) and ash (7–11%) contents. Glutamic acid, aspartic acid, proline, and leucine were the most abundantly found amino acids in both species. The predominant minerals in the leaf powder were calcium (826–1,530 mg/100 g), potassium (794–904 mg/100 g), and magnesium (286-431 mg/100 g). Pyridoxine (475.06 mg/100 g) and vitamin E (34.2 mg/100 g) were found only in MS. Niacin was found only in MO at 32.21 mg/100 g, whereas ascorbic acid was found in both species (3.89 and 6.19 mg/100 g dry weight for MO and MS, respectively). The results of the animal study showed that mice on a high-fat diet containing 0.1% MO leaf powder alleviated the elevation of cholesterol, triglycerides, and low-density lipoprotein cholesterol induced by the high fat diet. MO was more effective than MS in preventing hypercholesterolemia and fat deposition. CONCLUSIONS: The findings in this work confirmed that Moringa leaves of both MO and MS possessed high nutritional value but MO was better at preventing the harmful effects of the high-fat diet than MS.

RESUMO

As the incidence of chronic diseases such as diabetes and hypertension increases, complications such as decreased renal function are also increasing in many patients. Nutritional management in hemodialysis patients is a very important factor for prognosis and quality of life. The purpose of this study was to investigate the differences in nutritional status and dietary management according to hemodialysis duration. A total of 145 patients were divided into 4 groups according to hemodialysis duration: less 1 year (D1), 1–5 years (D2), and above 5 years (D3). The rates of protein-energy wasting were 31.1% in D1 group, 49.5% in D2 group, and 47.6% in D3 group. However, there was no significant difference between the 3 groups. Nutrient intake analysis showed that protein, iron, and vitamin C were significantly lower in the D3 group than in the D1 group. Protein intake in all 3 groups was insufficient compared to the recommended dietary amount for dialysis patients. The most difficult aspect in dietary management was cooking with low sodium. In the D3 group, which had the longest duration of dialysis, the practice of diet therapy and self-perceived need for nutrition education was lowest. Observations of nutritional status are necessary to maintain the health status of dialysis patients. In addition, education plans should be prepared to mediate the nutrient intakes and identify the patient's difficulties and provide practical help.

RESUMO

BACKGROUND/OBJECTIVES: This study investigated nutritional status of the elderly with dementia in a care facility with the aim of improving the meal quality of the facility. SUBJECTS/METHODS: Data were collected from 30 dementia patients aged more than 65 years in a long-term care facility in Hongseong. The data were obtained from questionnaires and medical records. The food intake data was obtained using food photographs and the nutrient intakes were calculated using the CAN-Pro 5.0. The data were compared with the dietary reference intakes for Koreans (KDRIs). The nutrient density, diet quality such as nutrient adequacy ratio (NAR), mean adequacy ratio (MAR), and index of nutritional quality (INQ), as well as dietary diversity score (DDS) were evaluated. The data were analyzed using SPSS statistical programs. RESULTS: The average daily energy intakes for men and women were much lower than the estimated energy requirements of the KDRIs. The average intakes of energy and most nutrients in the general diet group were significantly higher than those of the other two groups. Significant differences in diet quality and diet diversity were observed according to the meal type groups. The NARs of some minerals (calcium, iron, and zinc) and vitamins (vitamin B6 and folic acid) were less than 0.5 in all study groups. The NARs of protein, iron and MAR of the general diet group were significantly higher than those of the liquid diet group. The DDS scores of meats, fruits and diary food group were very low in all meal type groups, meaning that the diet qualities of the study subjects were not appropriate in all meal type groups. CONCLUSIONS: The food intakes of the study groups showed some limitations by a direct comparison with KDRIs because of the very low physical activities of the study subjects. The diet quality and diet diversity indices suggest the need for improvements in the nutritional quality in all types of diet. Overall, new intervention strategies targeting facility residents with dementia in Korea are needed as soon as possible.

RESUMO

BACKGROUND/OBJECTIVES: This study aims to develop a mobile nutritional management program for integration into the already developed web-based program, Diabetes Mellitus Dietary Management Guide (DMDMG) for diabetic patients. Further, we aim to evaluate the amended DMDMG program. SUBJECTS/METHODS: The mobile application based on an Android operating system includes three parts: 1) record of diet intake, which allows users to take pictures of the meal and save to later add diet records into DMDMG; 2) an alarm system that rings at each meal time, which reminds users to input the data; 3) displays the diet record and the results of nutrient intake, which can be also viewed through the web program. All three parts are linked to the web-based program. A survey was conducted to evaluate the program in terms of nutrition knowledge, dietary attitude, eating behavior and diet intake by non-equivalent control group design among diabetic patients with 14 DMDMG users and 12 non-user controls after a one-month trial of DMDMG. RESULTS: Non-users did not use the program, but participated in the weekly off-line nutrition classes for one month. The program users showed increased healthful dietary behavior (P < 0.01) and dietary attitude scores (P < 0.05). More DMDMG users had higher nutrition knowledge scores after one-month trial than non-users. However, dietary intake significantly increased in non-user group for calcium and sodium (P < 0.05) while the user group did not show significant changes. CONCLUSIONS: The program has created positive changes in patients' dietary life. All the users were satisfied with the program, although some expressed minor difficulties with an unfamiliar mobile app.

RESUMO

OBJECTIVES: The purpose of this study was to develop web-based self-nutrition management u-Health program for diabetic patients (DMDMG: Diabetes Mellitus Dietary Management Guide) for achieving systematic self-management of diet. METHODS: The program consisted of five parts with different contents according to the results of needs assessment. Five major parts were 1) meal management part which contains calorie prescription, meals recording and dietary assessment, 2) prevention of disease part with information of diabetes and assessment of dietary behavior, 3) dietary behavior modification part with an education on dietary behavior modification plan and dietary behavior plan, 4) meal plan containing a training section for meal plan and self constructing part for meal planning by making tables, and 5) information about myself which composed with general and physical information. The system proposed in this study provides nutrients intake results right after input of diet intake, which is possible with simultaneous calculation of input data in the server with 3,495 food and 1,821 meal data base. The nutrients analysis program was evaluated with 26 diabetic patients with two-day 24 hr recall. RESULTS: The differences of nutrients intakes between DMDMG and CANPRO 3.0 ranged from 13.5-16.5%, which was caused by the differences of databases of the two programs. The characteristics of DMDMG were; 1) it can provide an interactive tailored nutrition management, 2) it is a practical tool of diabetes nutritional management, 3) the program gives motivation for the dietary behavior modification. CONCLUSIONS: The effectiveness of whole program needs to be conducted, but the program was an innovative tool for self-management of nutrient intakes, diet behaviors, meal management and tailored nutrition education.

RESUMO

This study examined the total polyphenol content of eight wild edible plants from Ethiopia and their effect on NO production in Raw264.7 cells. Owing to its relatively high polyphenol concentration and inhibition of NO production, the methanol extract of Adansonia digitata L. leaf (MEAD) was subjected to detailed evaluation of its antioxidant and anti-inflammatory effects. Antioxidant effects were assessed by measuring free-radical-scavenging activity using 1,1-diphenyl-2-picrylhydrazyl (DPPH) and oxygen-radical-absorbance capacity (ORAC) assays, while anti-inflammatory effects were assessed by measuring inducible nitric oxide synthase (iNOS) expression in lipopolysaccharide (LPS)-stimulated RAW264.7 cells. In the ORAC assay, MEAD was 10.2 times more potent than vitamin C at eliminating peroxyl radicals. In DPPH assay, MEAD also showed a strong ROS scavenging effect. MEAD significantly inhibited iNOS activity (IC50=28.6 microg/ml) of LPS-stimulated Raw264.7 cells. We also investigated the relationship between iNOS expression and nuclear factor kappa B (NF-kappaB) activation. MEAD inhibited IkappaBa degradation and NF-kappaB translocation from the cytosol to the nucleus in LPS-induced RAW264.7 cells without significant cytotoxic effects, as confirmed by MTT assay. These results suggest that MEAD inhibits anti-inflammatory iNOS expression, which might be related to the elimination of peroxyl radicals and thus the inhibition of IkappaBa-mediated NF-kappaB signal transduction.

RESUMO

Variables affecting bone heath of growing children were analyzed among forty nine 10-12 year old elementary students in three rural regions of north west Chungnam area. Information on age of the parents, duration of breast feeding and birth weight were collected from the guardians of the participants and nutrient intake and diet quality were assessed by average of three-day food records of participants with the help of dietitians. Bone health status was measured by calceneal broadband ultrasound attenuation (BUA) using quantitative ultrasound (QUS). Results showed that anthropometic indexes and nutrient intake levels were not different between boys and girls. However, iron intake was significantly lower in girls than in boys. Girls after menarche showed lower intake levels for thiamin, riboflavin, pyridoxine and niacin than girls before menarche. z-scores of BMI were lower than -1 and higher than +1 showed shorter breast feeding period than others but the difference was statistically non-significant. Overall, the subjects did not consume enough s of calcium, vitamin C and folic acid. Zinc intake and BMI were the most significant factors affecting BUA by the results of backward elimination in multiple regression models. Phosphorous and beta-carotene intakes showed significant negative relation with BUA. This study showed that children living in the rural area of Chungnam need extra care to keep their health and nutrient intakes especially for the nutrients known to affect growth. Tailored nutrition education needs to be more focused on the improvement of bone health status of children.

RESUMO

This study aims to demonstrate the effect of farming technology on introducing medicinal plants (MP) and wild food plants (WFP) into a traditional agricultural system within peri-urban zones. Field investigations and semi-structured focus group interviews conducted in the Buhozi community showed that 27 health and nutrition problems dominated in the community, and could be treated with 86 domestic plant species. The selected domestic MP and WFP species were collected in the broad neighboring areas of the Buhozi site, and introduced to the experimental field of beans and maize crops in Buhozi. Among the 86 plants introduced, 37 species are confirmed as having both medicinal and nutritional properties, 47 species with medicinal, and 2 species with nutritional properties. The field is arranged in a way that living hedges made from Tithonia diversifolia provide bio-fertilizers to the plants growing along the hedges. The harvest of farming crops does not disturb the MP or WFP, and vice-versa. After harvesting the integrated plants, the community could gain about 40 times higher income, than from harvesting farming crops only. This kind of field may be used throughout the year, to provide both natural medicines and foods. It may therefore contribute to increasing small-scale crop producers' livelihood, while promoting biodiversity conservation. This model needs to be deeply documented, for further pharmaceutical and nutritional use.

RESUMO

This study was conducted to assess needs of self-management nutrition program for diabetic patients. The survey was conducted among 100 diabetic patients, and the mean age of the subjects was 54.2 years old. Thirty three percent of the subjects were diagnosed diabetes less than 2 years ago. The average nutrition knowledge score about diabetes was 10.2 point, and percentages of correct answers were very high in 'foods rich in fiber' (97.0%), 'relevance of exercise and insulin' (97.0%), 'quantity of insulin injection' (91.0%), and 'diabetes menu' (91.0%). The sources of nutrition information were hospitals/healthcare centers (56.1%), TV/radio (19.2%), and internet (13.1%). Sixty nine percent of the subjects have experienced nutrition education on subjects as 'menu planning skills' (22.4%), 'selecting foods' (22.4%), 'relevance of blood glucose and eating foods' (21.5%) by personal counseling (54.4%). The total score of eating behavior was higher after diagnosed diabetes (35.3) than before (30.0) (p < 0.001). The preferred topics in developing diabetes nutrition information websites were 'diabetes mellitus', 'relevance of blood glucose and foods', and 'selecting foods for diabetes'. The subjects wanted the websites developed by 'using mainly illustrations, pictures, tables' (22.8%) and 'using simple design' (19.6%). The preferred contents in developing diabetes self-management nutrition program were 'dietary life diagnosis', 'chronic disease risk diagnosis', 'calorie control by selecting foods and cooking skills', and 'dietary assessment'. In designing the program, the subjects' most wanted designs were 'be handy and simple in using' (29.3%), 'using simple design' (17.9%), and 'using mainly illustrations, pictures, tables' (15.7%).

RESUMO

The purpose of this study was to analyze the relationship of nutritional status measured by the body composition and dietary nutrients intakes with calcaneal broadband ultrasound attenuation in college students. Total of 886 (462 male and 424 female) students who received health examination in May 2007 participated in this research.Participants bone status was measured by a quantitative ultrasound method and t-score was calculated via WHO guideline. For body composition measurements, body fat, height and weight were measured and BMI was calculated. Dietary data were collected by a 24-hour recall method. Based on Asia-Pacific standard of WHO, BMI was divided into 3 groups; UW (BMI<18.5), NW + OW (18.5< or =BMI<25) and Obese group (25< or =BMI). Among male students, 2.4% belong to the UW group, 45.0% to the NW+OW group and 52.6% belong to the obese group, while 10.4% of female students belong to the UW group, 71.9% to the NW + OW group and 17.7% of female students belong to the Obese group. Differences among male and female students were statistically significant (p<0.001). Students with higher BMI showed significantly higher bone health status. Male students did not show any significant differences in nutrients intakes by BMI groups while female students showed the higher intakes of energy, protein, pyridoxin, phosphorus, iron and zinc among NW + OW group than other groups (p < 0.05). The qualitative and quantitative evaluation of diet by BMI groups did not show any significant differences in both male and female students. The result of the multiple regression analyses showed that the body fat and bone status was negatively related while energy intake was positively related with the bone status. These results revealed that bone health status was positively affected by BMI but not by body fat. In conclusion, among those who are at their twenties, the period when the bone density becomes maximized, body fat may negatively affect bone health unlike during other life cycle stages.

RESUMO

The purpose of this study was to investigate the effects of green tea ingestion on hepatocarcinogenesis before and after its initiation. Male Sprague-Dawley rats were fed an AIN76A diet with or without green tea. Initiation was induced by a single dose (200 mg/kg) of diethylnitrosamine at week 4 and 0.02% (w/w) 2-acetylaminofluorene was supplied in the diets. The control group had free access to water for 13 weeks (CTR13). Tea infusion was provided from the beginning of the experiment for 13 weeks (PRE13) or from the post-initiation stage until week 13 (POST13). Three other groups (CTR24, PRE24 and POST24) were added to examine the longer-term effects (24 weeks) with the same experimental design. The percentage area of liver sections that were positive for hepatic placental glutathione S-transferase (GST-P), which was used as a marker of preneoplastic lesions, was smaller in PRE13 (20.2 +/- 5.0%, mean +/- SD) and POST13 (26.0 +/- 4.8%) than in CTR13 (33.2 +/- 5.8%, p<0.05). Over the longer period, the GST-P lesions were significantly smaller for both PRE24 and POST24 (21.6 +/- 8.5% and 22.2 +/- 4.0%, respectively) than for CTR24 (28.6 +/- 5.1%, p<0.05), but there was no significant difference between PRE24 and POST24. The liver content of thiobarbituric acid reactive substances was significantly lower in the tea groups than in the controls (p<0.05). However, no significant differences were observed among groups of GST activity. The results show that tea consumption exhibits a stronger short-term initiation-inhibiting ability in liver carcinogenesis, but over a longer period, the preventive effects of green tea ingestion do not differ in post- and pre-initiation.

RESUMO

Intussusception of the appendix is not only extremely rare but also presents with symptoms similar to appendicitis. Therefore, preoperative diagnosis is unusual. On the other hand, appendiceal mucocele refers to obstructive dilatation of the appendiceal lumen caused by mucus. It has been reported in 0.2~0.3% of appendectomy specimens. A 22-year-old woman visited the Emergency Department because of right lower abdominal tenderness with hematochezia. Abdominal CT scan revealed a target sign in the right lower quadrant area that was suggestive of intussusception. The patient underwent emergency surgical reduction of the intussusception and appendectomy. The pathology showed an appendiceal mucocele.

RESUMO

The objective of this study was to assess the prevalence and clinical characteristics of anemia and to define the risk factors for anemia in older Koreans in Asan. From January to February 2002, five hundred sixty two community-dwelling older adults aged over 60 years were selected from a cross sectional study. All subjects underwent laboratory tests, which included a complete blood cell count, reticulocyte, liver and renal functional tests, lipid profiles and iron status tests. The median age was 68.6 years (range, 60-92 years). The mean levels of hemoglobin were 14.4 +/- 1.3 g/dL in men and 12.9 +/- 1.0 g/dL in women, and the overall prevalence of anemia was 12.5% in all subjects, 10.8% in men and 13.6% in women. The prevalence of anemia was the lowest among age group of 60-69 (10.0%) followed by 70-79 (15.5%), and the highest among age over 80 (20.7%), but the difference was significant only for men. The age difference was more distinct in men than in women (p<0.05). The mean hemoglobin level was significantly lower in the subjects aged over 80 y than those in the 60-69 y group (p<0.05). According to a logistic regression analysis, lower albumin and higher creatinine levels were identified as independent risk factors of anemia among older adults in Asan. In conclusion, the overall prevalence of anemia in our study group was 12.5% and the highest (20.7%) among those aged over 80 y.

RESUMO

Anthocyanin pigments from varieties of black, red and wild rice were identified and quantified to evaluate their potential as nutritional function, natural colorants or functional food ingredients. Anthocyanin extraction was conducted with acidified methanol with 0.1M HCl (85:15, v/v) and identification of anthocyanin, aglycone and sugar moieties was conducted by comparison with purified standards by HPLC, Ultraviolet-Visible absorption spectrophotometer and paper chromatography. Black and wild rice showed three different types of pigments by HPLC whereas red rice variety did not show any anthocyanins. Out of three pigments detected, one (peak 2) was characterized as cyanidin-3-glucoside (C3G) by comparison of spectroscopic and chromatographic properties with an authentic standard, and another (peak 3) was tentatively identified as cyanidin-fructoside on the basis of spectroscopic properties with lambdamax of aglycone in 1% HCl methanol at 537 nm, electrospray ionization mass spectra with major ions at 449 and 287 m/z and chromatographic properties. But another pigment (peak 1) has not been characterized. The most abundant anthocyanin in black and wild rice was C3G.

RESUMO

The objective of this study was to investigate the relation of serum calcium level, body mass index(BMI) with bone status expressed as broadband ultrasound attenuation(BUA) measured by quantitative ultrasound (QUS) and the occurrence of osteopenia among adult men and women. Two hundred eleven(63 male and 148 female) workers who worked in 4 different battery factories were recruited from March 2005 to October 2005. BUA was used as a surrogate of bone mineral density and measured at left calcaneous bone area. The BUA value transformed into T-score by WHO standard conversion criteria to determine osteopenia (-2.5

RESUMO

Inadequate dietary intakes and poor health behaviors are of concern among rural residents in Korea. This study is conducted to compare dietary intakes, dietary diversity score (DDS), mean nutrient adequacy ratio (MAR) and health related behaviors by rural, factory and urban areas in Asan. A total of 930 adults (351 men and 579 women) were interviewed to assess social economic status (SES), health related behaviors and food intakes by a 24-hour recall method. Mean age was 61.5 years with men being older (64.8 years) than women (59.3 years, p<0.001). Men in the factory area were older than rural or urban men while urban women were the youngest. Education and income of urban residents were higher than other area residents. There were more current drinkers in urban area while smoking status was not different by regions. Physical activity was significantly higher in rural or factory areas, whilst urban residents exercised more often (p<0.05). Rural or factory area residents considered themselves less healthy than others while perceived stress was lower than urban residents. Energy intakes were higher in urban residents or in men, however, after SES was controlled, energy intake did not show any differences. Energy-adjusted nutrient intakes were significantly higher in the urban area (p<0.05) for most nutrients except for carbohydrate, niacin, folic acid, vitamin B6, iron and fiber. Sodium intake was higher in factory area than in other areas after SES was controlled. DDS of rural men and MAR of both men and women in the rural area were significantly lower when SES was controlled. In conclusion, dietary intakes, diversity, adequacy and perceived health were poor in the rural area, although other health behaviors such as drinking and perceived stress were better than in the urban area. In order to improve perceived health of rural residents, good nutrition and exercise education programs are recommended.

RESUMO

The objective of this study is to determine the effectiveness of 16-month milk consumption as a part of the health promotion community program for women in Asan. Subjects included 313 women belonging to the milk group (mean age = 69.1, range 47~89 y) and 66 women to the control (mean age = 43.6, range 20~69 y) group. For those in the milk group, one cup (200ml) of partially lactose-digested low-fat milk was provided everyday for 16 months. Each subject was interviewed to assess calcium intake by a 24-h recall after fasting blood was obtained for analyzing bone turnover markers, and calcaneus broadband ultrasound attenuation (BUA) was measured by quantitative ultrasound (QUS) on the left heel before and after the milk supplementation. After 16 months, the calcium intake levels changed from 55% of recommended dietary allowance (RDA) to 85% RDA in the milk group and from 73% RDA to 84% RDA in the control group. BUA were reduced from 67.9+/-8.1 to 64.7+/-17.5 dB/MHz for milk and from 90.4+/-13.0 to 87.2+/-15.2 dB/MHz for control groups. Paired ttest showed the changes of BUA for both groups (-3.24 and -3.15 dB/MHz for milk and control groups, respectively) were significant, but the two groups did not show any differences in absolute changes. When post-BUA was analyzed after age, initial BUA and menopausal status were controlled as covariates in ANCOVA model, the milk group showed significantly (p < 0.05) smaller changes than the control group (-3.50 vs -6.71 dB/MHz, respectively). According to a multiple regression analysis, milk consumption and initial BUA showed significant interaction meaning that those with lower initial BUA showed higher milk effects. We conclude that one-cup a day milk consumption for 16 month can prevent further bone loss and significantly improve calcium intake.
