Obesity continues to be a major problem for many adult Americans. LIFESTEPS: Weight Management, a nutrition education program for adults developed by the National Dairy Council, was designed to help meet the need for effective programmming in the area of obesity. Based on principles of behavior modification and adult learning, the program is described and key features are discussed.
Objective of the study is to present an intervention model to evaluate nutritional risk of institutionalised elderly, suitably with the aims and resources of the Hygiene of Nutrition Services, and to individuate predictive variables of nutritional vulnerability. 237 subjects from the residential homes of ASL RMB were involved in the study; to each subject was administered: a) the Mini Nutritional Assessment (MNA); b) a questionnaire for the analysis of the risk factors. Multivariate logistic regression analysis was performed to evaluate the influence of the risk factors on nutritional status. On the basis of BMI the prevalence of malnutrition is 6.5% and the prevalence of overweight and obesity is respectively 41.6% and 22.9%; on the basis of MNA, 5.1% of the subjects is malnourished and 60.3% at risk for malnutrition. The absence of chewing difficulties (OR 2.94; I.C. 1.46-5.91) and the habit to eat all foods served at meals (OR 2.83; I.C. 1.46-5.91) are associated with a good nutritional status. The age > or = 90 years is a risk factor for malnutrition at the limit of statistical significance (OR 0.44; I.C. 0.14-1.00). Carrying out the MNA resulted easy and quick, confirming the hypothesis for feasibility of this protocol in the Hygiene of Nutrition Services. The results highlight an high nutritional risk of the elderly nursing home residents and the importance of planning programs of nutritional surveillance with particular attention on masticatory function impairments, meal intake and on the oldest subjects among the elderly as a group greatly vulnerable. We believe that these areas are very important in defining public health intervention programs.
The peer education model, which enables trained learners to instruct their peers, was tested in a case study involving senior citizens in a nutrition education program. The case study approach, using action research, was chosen because the project involved the description and analysis of a unique group of 32 mature adults. Topics selected for presentation in the three two-hour sessions were selected by open consensus of the entire participating body. Six members of the group volunteered to engage in a preliminary training program. These individuals became known as volunteer peer educators (VPE), who subsequently took full responsibility for disseminating the nutrition information to their peers. Educational materials to meet the goals of the program were compiled by the researcher in a resource manual for each of the volunteer peer educators. Techniques of participant observation for data collection and qualitative analysis were used. The satisfactory implementation of the program was due in great part to group selection of the learning episode; to a relaxed atmosphere; to enthusiasm on the part of the VPE; to the availability of a good resource manual and a facilitator who provided a strong organizational framework. The peer education model was found to be a particularly useful tool in providing nutrition information to a much broader sector of the senior population than can be currently reached via public health programs.
OBJECTIVE: To determine mean intake of energy and protein, total fat, saturated fat, percent energy from total and saturated fat, cholesterol, carbohydrate, calcium, iron, zinc, folate, vitamins A, C, E, B-6 and B-12, thiamin, niacin, riboflavin, magnesium, sodium and fiber of preschool Head Start children at school and away from school. DESIGN: Twenty-four-hour food intakes for 358 Head Start children were obtained by observing food intake at school and acquiring intake recalls from parents or guardians specifying food their children consumed for the balance of the day. After determining group estimates of energy and nutrient intake, mean intake was compared to standard nutrient recommendations for the entire 24-hour day, i.e., for the time the children were in school and for the remaining hours away from school ("home" intake). SUBJECTS: The 358 Head Start children attended school either half-day (2- to 3-hour AM and PM sessions) or all-day (5 to 6 hours). STATISTICAL ANALYSES: Differences in nutrient intake among class times were analyzed using one-way analysis of variance (ANOVA) followed by Tukey's multiple comparison test. Differences with a p-value <0.05 (two-tailed) were considered to be statistically significant. Total energy, protein, calcium, iron, zinc, vitamins A, C, E, B6, and B12, thiamin, niacin, riboflavin as well as folate and magnesium were compared to the Recommended Dietary Allowances for the 4- to 6-year-old age group. Other standards that were used for comparisons included the National Cholesterol Education Program (fat, saturated fat and cholesterol), the 1989 National Research Council's Diet and Health Report (carbohydrate and sodium) and the recommendation for fiber proposed by the American Health Foundation. RESULTS: At school, half-day children consumed up to 25% of the daily recommendation for energy and nutrients, while all-day children achieved at least a third of the recommended intakes. When intakes at home and school were combined, all three groups of children (AM, PM and all-day) exceeded dietary recommendations for protein, vitamins and minerals. Energy intake remained below 100% of the recommendation, while intake of total fat, saturated fat and cholesterol exceeded recommendations. APPLICATION: Further research is required to explore energy needs and determine nutritional status and nutrient needs of minority and low-income preschool children. Strategies are required to increase nutrient density, but not fat density, of meals and snacks served to children who attend day care for part of the day. Finally, school meals and nutrition education programs such as Team Nutrition should broaden their base to include healthful eating habits for all school children, including the very youngest children in preschool programs.

The Navy wants to incorporate nutrition education programs into basic training to teach Navy personnel fundamental principles of good nutrition. This study was undertaken to: determine deficits in recruits' nutrition knowledge, identify recruits with above-average need for nutrition education, and compare recruits' nutrition knowledge with that of typical U.S. school students. Demographic information and responses to a shortened version (36 items) of the National Dairy Council's Nutrition Achievement Test 4, developed for junior and senior high school students, were obtained from 205 male recruits. Although nutrition knowledge among Navy recruits was relatively comparable with that of U.S. school students, findings indicated that nutrition education is indeed needed. Only 2% of recruits answered 90% of the questions correctly. Forty percent answered half or more of the nutrition questions incorrectly. Questions answered incorrectly by more than 50% of recruits involved: (a) how one assesses nutrient needs and whether those needs are being met, (b) the four major food groups and recommended servings, and (c) effects of alcohol and drugs on nutritional status. Recruits who received higher grades in high school, got into less trouble in high school, were older, and were Caucasian had higher nutrition knowledge. Detailed information regarding nutrition misconceptions should help the Navy develop focused nutrition education materials.
In a cross-sectional study the effects of several nutritional factors on the manifestations of osteoporosis were investigated in 23 postmenopausal women aged 50 to 70 years. Twelve women (group 1) with osteoporosis and eleven healthy control subjects (group 2) were instructed to keep a seven-day nutritional record. Body mass index (BMI) was recorded, and radiological and bone mineral density investigations were undertaken. The daily total energy, protein, fat, carbohydrate, fiber, oxalic acid, calcium, magnesium, phosphorus, sodium, fluoride, zinc, copper, manganese, vitamin C, D, and K intake were analysed within the framework of a nutritional science program. No intergroup differences were observed with regard to total energy intake, nutritional components and BMI; however, age and years since the menopause differed significantly (p < 0.05). The results suggest that the manifestation of osteoporosis in women is influenced to a greater extent by age and years since the menopause than by the distribution of nutritional factors in a normal mixed diet. However, further studies are essential to evaluate the role of dietary composition on the manifestations of osteoporosis.
