“…The daily energy and nutrient intakes of the study groups were compared using Student's t test, and differences were considered significant at P , 0?05. The proportion of children with inadequate dietary intake in each group was evaluated by estimating the percentage of individuals whose daily intake was less than the EAR (equivalent to 0?77 of the RDA) for the nutrient under consideration (5)(6)(7) . However, because there are no RDA for EFA, the lower limit of the AI (5) was used for these nutrients (linoleic acid and a-linolenic acid).…”

Objective: To evaluate the nutritional adequacy of diets in early childhood as a function of milk intake, cows' milk (CM) or growing-up milk (GUM). Design: From a cross-sectional food consumption survey, two groups of children aged 1-2 years were defined: Group CM fed exclusively on CM $ 250 ml/d and Group GUM fed on GUM $ 250 ml/d. Proportions of children at risk of nutrient excess or insufficiency were estimated relative to the French Recommended Daily Allowances, Estimated Average Requirements or Adequate Intakes. Setting: Parents participating in the survey were recruited from all regions of France by a polling organization. Distribution was adjusted to that of the French population. Subjects: Sixty-three (Group CM) and fifty-five (Group GUM) children. Results: Total energy and macronutrient intakes were similar in the two groups except protein intake of Group CM, which was much higher than the Recommended Daily Allowance and significantly higher than in Group GUM. A high percentage of children of Group CM had intake of linoleic acid (51 %) and a-linolenic acid (84 %) below the lower limit of the Adequate Intake, and intake of Fe (59 %) vitamin C (49 %) and alimentary vitamin D (100 %) less than the Estimated Average Requirement. Significant differences were observed in the proportions of children with a risk of dietary inadequacy between the two groups for all the mentioned nutrients (P , 0?001). In Group GUM, this imbalance was only observed for vitamin D. Intake of foods other than milk and dairy products could not account for these discrepancies. Conclusions: Consumption of CM ($250 ml/d) entails the risk of insufficiency in a-linolenic acid, Fe, vitamin C and vitamin D. Use of GUM ($250 ml/d) significantly reduces the risk of insufficiencies in the mentioned nutrients.

“…The inclusion of individuals who under-report energy intake could overestimate by up to 17% the prevalence of inadequacy. 16 According to Poslusna et al (2009), 30% of underestimated iron, calcium or vitamin C intake may be related to under reporting. 21 On the other hand, the estimates of usual intake in the present study were based on appropriate statistical methods, adjusting distribution by intra-individual variability which removed extremes considered to be unlikely, for both over-and under-estimates of intake.…”

OBJECTIVE: To estimate energy and nutrient intake and prevalence of inadequate micronutrient intake among Brazilian adults. METHODS:Data from the National Dietary Survey, from the [2008][2009] Household Budget Survey, were used. Food consumption was evaluated through food record on two non-consecutive days. A total of 21,003 individuals (52.5% women), between 20-59 years old, participated in the survey. Usual nutrient intake was estimated according to the National Cancer Institute method. The Estimated Average Requirement (EAR) cut-off points were used to determine the prevalence of inadequate micronutrient intake. For manganese and potassium, the Adequate Intake (AI) was used as cut-off. Sodium intake was compared with the Tolerable Upper Intake Level (UL). The probability approach was used to determine the prevalence of inadequate iron intake. The data were analyzed according to the location of the household (urban or rural) and macro regions of Brazil. RESULTS:The mean energy intake was 2,083 kcal among men and 1,698 kcal among women. Prevalence of inadequacy equal to or greater than 70% were observed for calcium among men and magnesium, vitamin A, and sodium among both men and women. Prevalence equal to or greater than 90% were found for calcium in women and vitamins D and E in both genders. Prevalence lower than 5% were found for iron in men and for niacin in men and women. In general, prevalence of inadequate intake was higher in the rural area and in the Northeast region. CONCLUSIONS:Energy intake was higher among individuals who live in urban areas and in the North region. The greatest risk groups of inadequate micronutrient intake were women and those living in rural areas and in the Northeast region.

“…The Estimated Average Requirement (EAR) cut-point method is a well-known procedure for evaluating nutrient intakes of groups (16)(17)(18), and we adopted it to assess the proportion of the population at risk for inadequacy. To evaluate the proportion of the population at risk for nutrient excess (and calcium deficiency) we used the dietary goals for preventing life-style related diseases (DG) on the adjusted and unadjusted distributions of dietary intake data.…”

SummaryThe health of individuals is not markedly affected by the nutrients ingested in a single day; rather it is influenced by dietary habits over a long period of time. However, it is impossible to survey usual intake directly because recording diet over a long period of time is burdensome for the subjects, so usual dietary intake is rarely measured directly. Instead, we estimated the distribution of selected nutrients in subjects' usual dietary intake using a statistical method (Best-Power method) described previously. And we assessed the proportion of nutritionally at-risk subjects in individual groups based on the new Japanese Dietary Reference Intakes (DRIs), the Estimated Average Requirement (EAR), or the tentative dietary goal for preventing life-style related diseases (DG) as cut-points. We collected the survey data from 208 men and 251 women, aged 50 to 69 y in 2004 and 2005. The survey was carried out on three non-consecutive days four times each year: in spring, summer, autumn, and winter. The distribution of nutrients in the usual intake was estimated from a dietary survey of 3 d using one-way analyses of variance. We found that the proportion of the population at risk for nutrient deficiency was overestimated in the 1-d intake distribution. On the other hand, the fraction that was nutritionally at-risk in terms of salt intake, according to DG as the cut-point, was underestimated in the 1-d intake distribution: 74.0% of men and 82.5% of women in the 1-d intake, and 90.5% and 93.2%, respectively, for the estimated usual intake adjusted for seasonal variation.
