Energy And Nutrient Intake

This study evaluated the tracking of energy and nutrient intakes, assessed by diet history, in a random sample of adolescents (boys n 225, girls n 230) at baseline (age 12 years), and subsequently at age 15 years. Median energy (MJ/d) and macronutrient (g/d) intakes increased significantly (all P<0·001) with increasing age in the boys. The girls' reported energy intake (MJ/d) remained stable over time, despite significant increases in BMI, weight and % body fat. Age-related changes in the girls' macronutrient intakes were inconsistent. When expressed in terms of nutrient density, the diets of both sexes became significantly richer, over time, in total folate (both sexes, P<0·01), but poorer in Ca (boys P<0·01, girls P<0·001) and riboflavin (both sexes P<0·001). Vitamin B6 (P<0·001) and Fe (P<0·05) densities increased in the boys, while the thiamin density of the girls' diets decreased (P<0·001). Tracking, defined as maintenance of rank over time, was summarised using weighted kappa statistics (κ). There were some significant changes in intakes at the group level; however, tracking of energy and nutrients in both sexes was only poor to fair (κ<0·40), indicating substantial drift of individuals between classes of intake over time. Particularly poor tracking was evident for % energy from sugars (κ 0·09) and total fat (κ 0·09) in the girls' diets. In conclusion, the poor to fair tracking observed in this cohort suggests that individual dietary patterns exhibited at 12 years of age are unlikely to be predictive of energy and nutrient intake at age 15 years.

AbstractObjectiveTo assess tracking of energy and nutrient intakes between adolescence and young adulthood.DesignLongitudinal study of a random sample of adolescents (aged 15 years at baseline). The extent of tracking of dietary intakes (assessed by diet history) was investigated using weighted kappa statistics (κ).SettingNorthern Ireland population survey.SubjectsAdolescents who participated in the Young Hearts Project, Northern Ireland at age 15 years, and subsequently at young adulthood aged between 20 and 25 years (n = 245 males,n = 231 females).ResultsDespite overall increases in height and weight (bothP < 0.001), increases in body mass index in males (P < 0.001) and body fatness in females (P < 0.001), median reported intakes of energy (kJ kg− 1 day− 1), carbohydrate (g day− 1) and fat (g day− 1) decreased (allP < 0.001) over time. Expressed as nutrient densities (per MJ), diets at young adulthood were overall richer in thiamin, vitamin B6, total folate (allP < 0.001), vitamin C (P < 0.01) and vitamin D (P < 0.05). Whereas the nutrient density of the males' diets decreased over time for calcium (P < 0.05) and vitamin A (P < 0.001), iron and riboflavin densities increased in the females' diet (P < 0.001). Tracking of energy (MJ day− 1) and nutrient intakes (expressed per MJ day− 1) at the individual level was only poor to fair (all κ < 0.25), indicating substantial drift of subjects between the low, medium and high classes of intake with increasing age.ConclusionsThese data suggest that individual dietary patterns exhibited at 15 years of age are unlikely to be predictive of dietary intakes at young adulthood.

AbstractObjectiveThe present study evaluates the reliability and validity of an FFQ designed for use with adolescents in urban Vietnam.DesignA cohort study was conducted between December 2003 and June 2004. The FFQ was administered three times over a 6-month period (FFQ 1–3) and nutrient intakes were compared to those obtained from four 24 h recalls collected over the same period (24 h recalls 1–4) using crude, energy-adjusted and de-attenuated correlation coefficients. The level of agreement between the two measurements was also evaluated with Bland–Altman analysis. The percentage of nutrient intakes classified within one quintile, as well as quadratic-weighted kappa statistics, were calculated.SettingHo Chi Minh City, Vietnam.SubjectsA total of 180 students were recruited in three junior high schools.ResultsCoefficients ranged from 0·22 for retinol to 0·78 for fibre for short-term reliability, and from 0·30 for retinol to 0·81 for zinc for long-term reliability. Coefficients for nutrient intakes between the mean of the three FFQ and mean of four 24 h recalls were mostly around 0·40, but higher for energy-adjusted nutrients. After allowing for within-person variation, the mean coefficient was 0·52 for macronutrients and 0·46 for micronutrients. There were a relatively high proportion of nutrient intakes classified within one quintile and a small number grossly misclassified. Kappa values shows ‘fair’ to ‘good’ agreement for all food/nutrient categories, while the Bland–Altman plots indicated that the FFQ is accurate in assessing nutrient intake at a group level.ConclusionsThis newly developed FFQ is a valid tool for measuring nutrient intake in adolescents in urban Vietnam.

AbstractObjectiveTo examine the relative validity of an FFQ based on parental report for pre-school children in the mother–child ‘Rhea’ birth cohort.DesignThe children’s mothers completed an FFQ that referred to the children’s dietary intake for the previous year by telephone interview. Mothers completed also three food records, two on weekdays and one on a weekend day. Spearman correlation coefficients were calculated for the energy-adjusted values. Weighted kappa statistics (κw) and the Bland–Altman technique were used to test the degree of agreement between the two dietary methods.SettingHeraklion, Crete, Greece, 2011–2012.SubjectsA total of ninety-nine mothers (corresponding to fifty-one boys and forty-eight girls) participated in the validation study.ResultsThe mean and median values of all food group and nutrient intakes did not differ significantly between the two dietary methods. Overall, fair agreement was observed between the FFQ and the food records for ranking participants based on their intake, with κw ranging from 0·21 to 0·40 for most foods and nutrients. On average, 88 % of participants were classified into the same or adjacent tertiles for nutrient and food group intakes by both dietary methods. The degree of agreement was also confirmed by the visual examination of the Bland–Altman plots.ConclusionsThe study indicates that the Rhea 4 years FFQ is a relatively accurate tool for assessing habitual food group and nutrient intakes among pre-school children in Crete, Greece.

AbstractObjectives:The purpose of this paper is to present longitudinal data on nutrient intakes of youth with emphases on differences by sex and race/ethnicity. Nutrients selected for examination are those implicated in chronic disease.Design:24-hour dietary recalls were collected from a cohort of third, fifth and eighth graders (n=1874).Setting and subjects:The sample is drawn from the Child and Adolescent Trial for Cardiovascular Health and includes students from California, Louisiana, Minnesota and Texas.Results:Across the total sample, nutrient intakes met recommended levels except that total fat, saturated fat and sodium consistently exceeded recommendations and calcium and iron intake of girls consistently fell short of recommended levels. Nutrient consumption between third and eighth grade differed by sex and race/ethnicity for a number of nutrients. In particular, females' intake of energy from total fat, calcium, iron, folic acid, vitamin A and vitamin D decreased over time relative to males' intakes, controlling for overall energy intake. Compared with the other ethnic/racial groups, African-American students increased their intake of energy from total fat and saturated fat over time.Conclusions:Our results suggest that the diets of youth change over time, and negative trends are more common in females than in males and in African-American and Hispanics compared with Caucasian students. Nutrition education and intervention are needed throughout childhood and adolescence with an emphasis on choosing healthful foods. In addition, greater attention to differential opportunities and reinforcements for females and males, and Caucasian, Hispanic and African-American students is warranted.

AbstractA limited number of studies have examined associations between nut consumption and nutrient intakes or diet quality. None has investigated these associations in the Southern Hemisphere. The purpose of this study was to examine associations between nut consumption and nutrient intakes among adult New Zealanders. Data from the 24-h recalls of 4721 participants from the cross-sectional 2008/09 New Zealand Adult Nutrition Survey (2008/09 NZANS) were used to determine whole nut intake and total nut intake from all sources as well as nutrient intakes. Regression models, both unadjusted and adjusted for potential confounders, were used to estimate differences in nutrient intakes between those consuming and those not consuming nuts. From adjusted models, compared with non-whole nut consumers, whole nut consumers had higher intakes of energy and percentage of energy from total fat, MUFA and PUFA, whereas percentage of energy from SFA and carbohydrate was lower (all P≤0·025). After the additional adjustment for energy intake, whole nut consumers had higher intakes of dietary fibre, vitamin E, folate, Cu, Mg, K, P and Zn (all P≤0·044), whereas cholesterol and vitamin B12 intakes were significantly lower (both P≤0·013). Total nut consumption was associated with similar nutrient profiles as observed in whole nut consumers, albeit less pronounced. Nut consumption was associated with better nutrient profiles, especially a lower intake of SFA and higher intakes of unsaturated fats and a number of vitamins and minerals that could collectively reduce the risk for chronic disease, in particular for CVD.

AbstractPurposeThe Oxford WebQ is a web-based 24-hour dietary assessment method which has been used in UK Biobank and other large prospective studies. The food composition table used to calculate nutrient intakes has recently been replaced with the UK Nutrient Databank, which has food composition data closer in time to when participants completed the questionnaire, and new dietary variables were incorporated. Here we describe the updated version of the Oxford WebQ questionnaire nutrient calculation, and compare nutrient intakes with the previous version used.Methods207,144 UK Biobank participants completed ≥1 Oxford WebQs, and means and standard deviations of nutrient intakes were averaged for all completed 24-h dietary assessments. Spearman correlations and weighted kappa statistics were used to compare the re-classification and agreement of nutrient intakes between the two versions.Results35 new nutrients were incorporated in the updated version. Compared to the previous version, most nutrients were very similar in the updated version except for a few nutrients which showed a difference of >10%: lower with the new version for trans-fat (−20%), and vitamin C (−15%), but higher for retinol (+42%), vitamin D (+26%) and vitamin E (+20%). Most participants were in the same (>60%) or adjacent (>90%) quintile of intake for the two versions. Except for trans-fat (r=0.58, κ=0.42), very high correlations were found between the nutrients calculated using the two versions (r>0.79 and κ>0.60).ConclusionSmall absolute differences in nutrient intakes were observed between the two versions, and the ranking of individuals was minimally affected, except for trans-fat.

The Relationship

The rotary diversified diet, used in the management of environmental illness, consists of eliminating prohibited foods from the diet and rotating remaining non-prohibited foods and their “food families” within a regular cycle. We assessed the adequacy of nutrient intakes in 22 women prescribed the diet, described the nature of supplement use, and assessed the relationship between adherence and nutrient intake levels. Except for calcium and folacin intakes, mean nutrient intakes met or exceeded recommended levels. No subjects had calcium intakes above the adequate intake for calcium; 72.7% had folate intakes below the estimated average requirement. Intakes of other nutrients, except thiamin and magnesium, were below the estimated average requirement in less than 25% of the sample; 31.8% and 45.5% of subjects, respectively, had thiamin and magnesium intakes at this level. Those who adhered more closely to the rotary diversified diet had higher intakes of vitamin C, vitamin B6, folate, and fibre than did those who followed the diet less closely. Supplements conferred some nutritional benefits; however, supplemental niacin and magnesium intakes exceeded tolerable upper intake levels. Those prescribed the rotary diversified diet require nutrition counselling from dietitians to cope with the complexity and restrictiveness of the diet.

Background: The ongoing demographical shift is leading to an unprecedented aging of the population. As a consequence, the prevalence of age-related diseases, such as atherosclerosis and its thrombotic complications is set to increase in the near future. Endothelial dysfunction and vascular stiffening characterize arterial aging and set the stage for the development of cardiovascular diseases. Atherosclerotic plaques evolve over time, the extent to which these changes might affect their stability and predispose to sudden complications remains to be determined. Recent advances in imaging technology will allow for longitudinal prospective studies following the progression of plaque burden aimed at better characterizing changes over time associated with plaque stability or rupture. Oxidative stress and inflammation, firmly established driving forces of age-related CV dysfunction, also play an important role in atherosclerotic plaque destabilization and rupture. Several genes involved in lifespan determination are known regulator of redox cellular balance and pre-clinical evidence underlines their pathophysiological roles in age-related cardiovascular dysfunction and atherosclerosis. Objective: The aim of this narrative review is to examine the impact of aging on arterial function and atherosclerotic plaque development. Furthermore, we report how molecular mechanisms of vascular aging might regulate age-related plaque modifications and how this may help to identify novel therapeutic targets to attenuate the increased risk of CV disease in elderly people.

Growth And Reproduction

Many studies have examined the proportion of time that primates devote to feeding on various types of food, but relatively little is known about the intake rates associated with each food. However, the nutritional consequences of foraging can only be interpreted by comparing nutrient intakes with estimated nutrient requirements. The energy available to primates from ingested foods will depend both on the composition of the food and the extent to which various constituents, including fibre fractions, are digested. Both human and non-human primates have relatively low requirements for protein as a consequence of slow growth rates, small milk yields and relatively dilute milk. Because the nutrient demands of growth and reproduction are spread out over time, it appears that primates do not need to seek out foods of particularly high nutrient density, except perhaps during weaning. Although food selection in some species of primates appears to be correlated with the protein concentration of foods, it is unlikely that high dietary protein levels are required, at least when foods of balanced amino acid composition (such as leaves) are included in the diet.

Abstract Background For 10 consecutive years, the ESPN/ERA-EDTA Registry has included data on children with stage 5 chronic kidney disease (CKD 5) receiving kidney replacement therapy (KRT) in Europe. We examined trends in incidence and prevalence of KRT and patient survival. Methods We included all children aged <15 years starting KRT 2007–2016 in 22 European countries participating in the ESPN/ERA-EDTA Registry since 2007. General population statistics were derived from Eurostat. Incidence and prevalence were expressed per million age-related population (pmarp) and time trends studied with JoinPoint regression. We analyzed survival trends using Cox regression. Results Incidence of children commencing KRT <15 years remained stable over the study period, varying between 5.5 and 6.6 pmarp. Incidence by treatment modality was unchanged over time: 2.0 for hemodialysis (HD) and peritoneal dialysis (PD) and 1.0 for transplantation. Prevalence increased in all age categories and overall rose 2% annually from 26.4 pmarp in 2007 to 32.1 pmarp in 2016. Kidney transplantation prevalence increased 5.1% annually 2007–2009, followed by 1.5% increase/year until 2016. Prevalence of PD steadily increased 1.4% per year over the entire period, and HD prevalence started increasing 6.1% per year from 2011 onwards. Five-year unadjusted patient survival on KRT was around 94% and similar for those initiating KRT 2007–2009 or 2010–2012 (adjusted HR: 0.98, 95% CI:0.71–1.35). Conclusions We found a stable incidence and increasing prevalence of European children on KRT 2007–2016. Five-year patient survival was good and was unchanged over time. These data can inform patients and healthcare providers and aid health policy makers on future resource planning of pediatric KRT in Europe.
