Association of food insecurity with dietary intakes and nutritional biomarkers among US children, National Health and Nutrition Examination Survey (NHANES) 2011–2016
Food insecurity was associated with compromised intake of some micronutrients, especially among adolescent girls. These results highlight a need for targeted interventions to improve children's overall diet quality, including the reduction of specific nutrient inadequacies, especially among food-insecure children. This study was registered at clinicaltrials.gov as NCT03400436.
Older adults with obesity have higher risks of some micronutrient inadequacies and lower overall dietary quality compared to peers with a healthy weight, National Health and Nutrition Examination Surv…
Objective: To evaluate total usual intakes and biomarkers of micronutrients, overall dietary quality and related health characteristics of US older adults who were overweight or obese compared with a healthy weight. Design: Cross-sectional study. Setting: Two 24-h dietary recalls, nutritional biomarkers and objective and subjective health characteristic data were analysed from the National Health and Nutrition Examination Survey 2011–2014. We use…
Update on NHANES Dietary Data
Challenges in assessing the implementation and effectiveness of physical activity and nutrition policy interventions as natural experiments
The Ontario (Canada) government has instituted a policy requiring elementary schools to offer at least 20 min of daily physical activity for students in Grades 1-8 and replace non-nutritious vending machine foods with healthier choices. These policy interventions represent 'natural experiments' offering unique opportunities for conducting research and evaluation. The use of natural experiments to contribute evidence on the effectiveness of policy…
Validity and reliability of a calcium checklist in early elementary-school children
Objective To create, validate and assess the reliability of a checklist to measure calcium intake in children. Design Calcium intakes from a checklist and parent-assisted 24-h dietary recall were compared. Checklist reliability was assessed separately. Setting After-school programmes in the United States. Subjects Forty-two children (18 males, 24 females, age = 8.0 ± 0.9 years) participated in the validation analysis and 49 children (28 males, 21…
Intake of specific flavonoids and risk of acute myocardial infarction in Italy
High intake of anthocyanidins reduced the risk of AMI even after allowance for alcohol, fruit and vegetables, supporting a real inverse association between this class of flavonoids and AMI risk
Nutrient intake over time in a multi-ethnic sample of youth
Objectives: 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 inc…

Measuring flavonoid intake
Objective: Flavonoids are phytochemicals with potentially beneficial biological effects that are poorly characterised in existing tables of food composition. Design: To describe new techniques for analysis, absorption, informatics and dietary assessment that are important in measuring the flavonoid content in foods and in developing a flavonoid food composition database. Setting: Data on chemical analyses of the major flavonoid compounds that exi…
Nonsurgical Factors That Influence the Outcome of Bariatric Surgery
OBJECTIVE: Severe obesity (ie, at least 100% overweight or body mass index > or =40 kg/m2) is associated with significant morbidity and increased mortality. It is apparently becoming more common in this country. Conventional weight-loss treatments are usually ineffective for severe obesity and bariatric surgery is recommended as a treatment option. However, longitudinal data on the long-term outcome of bariatric surgery are sparse. Available data…
The distribution of body fat from childhood to adulthood in a longitudinal study population
Body fat distribution, its continuity from childhood (4–6 years) to 30 years of age, and its link to that of parents is described in a longitudinal study population. A computer-assisted image analysis technique was used to measure body fat distribution (as measured by waist and hip diameters) from somatotype photographs. Pearson correlation coefficients were used to assess the association between the waist/hip diameter ratio (WHDR) and the body m…
The measurement of body fat distribution using somatotype photographs and computer-assisted imaging techniques
A computer-assisted image analysis technique has been devised which allows the measurement of body fat distribution from archived somatotype photographs. This report describes the technique, which enables useful measurements to be extracted from somatotype photographs which were taken over 50 years ago. This paper describes the process of digitization of photographs, the measurement of body diameters using computer-assisted edge detection, the qu…

Diet, indicators of kidney disease, and later mortality among older persons in the NHANES I Epidemiologic Follow-Up Study
OBJECTIVES. The purpose of this study was to determine whether diet adversely affected survival among 2572 older persons with indicators of kidney disease in a population-based cohort. Average follow-up time for survivors, of whom 1453 (57%) had died at analysis, was 14.5 years. METHODS. Kidney disease indicators were a "yes" response to "Has a doctor ever told you that you have kidney disease or renal stones?" and/or trace or greater amounts of …
Accuracy of recall by middle-aged participants in a longitudinal study of their body size and indices of maturation earlier in life
The validity of long-term recall and current assessments of height, weight, and fatness relative to peers was investigated among 91 middle-aged participants in a longitudinal growth study. The recollections of 50-year-old participants concerning perceived body size in comparison to peers during childhood (aged 5-7 years), adolescence (aged 10-18 years), and at ages 30, and 40 years were compared with physical measurements taken at these times. Co…
Accuracy of recalled smoking data
Validity of recalled cigarette data was assessed among 87 middle-aged adults by comparing recall to longitudinal records. Agreement on smoking status and amount smoked 20 years ago occurred for 87 per cent and 71 per cent of subjects, respectively. Corresponding proportions for 32-year recall were 84 per cent and 55 per cent. Gender did not influence recall accuracy. Ex-smokers tended to make the most errors. Accuracy of recalled smoking informat…
Attitudes toward Voluntary Surgical Contraception in Four Districts of Kenya
A series of 32 focus groups were held among men and women in the catchment areas of four active voluntary surgical contraception (VSC) programs in Kenya. Women who had had tubal ligation and their husbands were uniformly favorable to this method. The majority of couples using reversible methods saw tubal ligation as a logical future choice. Participants were frank about economic motives, and many were willing to endure criticism of the older gene…

How Do Teachers Transmit their Attitudes and Expectations
In an earlier article (The Aborignal Child at School, Vol.7, No.3, 1979) I explored the idea that we, as teachers, may transmit our attitudes and expectations to our pupils through our accommodating and non-accommodating moves towards them. I suggested that we might observe such moves if we monitored our language behaviour against our intentions, as these are modified by our beliefs and attitudes, and by the on-going interaction. I proposed a mod…

The School and the Aboriginal Child
Uffela bin pinkin in a girl toilet!" The speaker was Norman, a somewhat crestfallen seven year old Aboriginal boy who had been sent to my office by a teacher on playground duty. Norman knows no Aboriginal language, and if asked, would state that he speaks English. His parents and friends would make a similar claim. I had been at the school long enough to know that Norman was guilty of throwing stones into the girls' toilet. His defence was that D…
The Social Psychology of Dieting
weight problems and of weight control efforts in the United States. It explores factors that may influence people to engage in weight control behavior in the first place and to choose dieting over other methods of reducing. It advances explanations to account for differences in the prevalence of dieting phenomena among various age and sex groups. Finally, it suggests several ways of improving the effectiveness and coverage of weight control progr…
