Dietary assessment in Whitehall II: comparison of 7d diet diary and food-frequency questionnaire and validity against biomarkers

The aim of the present cross-sectional study was to examine the agreement and disagreement between a 7 d diet diary (7DD) and a self-administered machine-readable food-frequency questionnaire (FFQ) asking about diet in the previous year, and to validate both methods with biomarkers of nutrient intake. The subjects were an age- and employment-grade-stratified random subsample of London-based civil servants (457 men and 403 women), aged 39–61 years, who completed both a 7DD and a FFQ at phase 3 follow-up (1991–1993) of the Whitehall II study. Mean daily intakes of dietary energy, total fat, saturated, monounsaturated and polyunsaturated fatty acids, linoleic acid, total carbohydrate excluding fibre, sugars, starch, dietary fibre, protein, vitamin C, vitamin E (as α-tocopherol equivalents), folate, carotenes (as total β-carotene activity), Fe, Ca, Mg, K and alcohol were measured. Serum cholesteryl ester fatty acids (CEFA), plasma α-tocopherol and β-carotene were also measured as biomarkers. Estimates of mean energy intake from the two methods were similar in men, and some 10 % higher according to the FFQ in women. Compared with the 7DD, the FFQ tended to overestimate plant-derived micronutrient intakes (carotenes from FFQ v. 7DD men 2713 (SD 1455) V. 2180 (sd 1188) μg/d, women 3100 (sd 1656) v. 2221 (sd 1180) μg/d, both differences P<0·0001) and to underestimate fat intake. Against plasma β-carotene/cholesterol, carotene intake was as well estimated by the FFQ as the 7DD (Spearman rank correlations, men 0·32 v. 0·30, women 0·27 v. 0·22, all P≤0·0001, energy-adjusted data). Ranking of participants by other nutrient intakes tended to be of the same order according to the two dietary methods, e.g. rank correlations for CEFA linoleic acid against FFQ and 7DD estimates respectively, men 0·38 v. 0·41, women 0·53 v. 0·62, all P≤0·0001, energy-adjusted % fat). For α-tocopherol there were no correlations between plasma level and estimated intakes by either dietary method. Quartile agreement for energy-adjusted nutrient intakes between the two self-report methods was in the range 37–50 % for men and 32–44 % for women, and for alcohol, 57 % in both sexes. Disagreement (misclassification into extreme quartiles of intake) was in the range 0–6 % for both sexes. The dietary methods yielded similar prevalences (about 34 %) of low energy reporters. The two methods show satisfactory agreement, together with an expected level of systematic differences, in their estimates of nutrient intake. Against the available biomarkers, the machine-readable FFQ performed well in comparison with the manually coded 7DD in this study population. For both methods, regression-based adjustment of nutrient intake to mean dietary energy intake by gender appears on balance to be the optimal approach to data presentation and analysis, in view of the complex problem of low energy reporting

Archival Preservation: Continuing Education for the Working Archivist

A recent exchange of letters in the American Archivist highlights the conflicts between the two schools promoting preservation education in the archival world today. Mary Lynn Ritzenthaler speaks for the commonsense school, which has also been represented most ably by George Cunha and Robert Patterson. They are dedicated to \u27action now\u27, because, to quote Patterson, the library and archives professions cannot afford to wait for the professional conservator to appear before taking up the battle against decay: we must organize to take action ourselves. Ritzenthaler was responding to Christine Young\u27s contention that a highly trained, highly skilled conservator is the key person in the physical preservation of historical documents

Evaluation of valued youth: a national peer-tutoring programme to increase self confidence and motivation

Established first in the USA, Valued Youth has operated in the UK since 1996, and is currently implemented in about 50 schools in 8 regions. The programme is intended to help secondary school students who are at risk of disengaging with school or underperforming for a variety of reasons. These students are selected as tutors, given training on how to work with younger children and placed in a local primary school where they support pupils' learning. Valued Youth can be seen as one of many initiatives in secondary schools on re-engagement in learning and contributes to the UK government strategy of extending opportunities and providing flexible learning experiences to meet individual learners' needs and aptitudes. Evidence from the USA has shown the value of the programme in reducing drop-out, strengthening youngsters' perceptions of self and school, and reducing disciplinary referrals and absenteeism. The evaluation discussed in this paper considers the effect of the programme in a UK context, not only in terms of young people's attendance, attainment and confidence, but also in terms of what sort of youngsters seem to benefit and the effects of financial rewards, if any, on the outcomes. The paper reports on the first year of a two-year evaluation. Data were obtained from a pre- and post-questionnaire survey among tutors, a workshop with coordinators and visits to selected case study schools in several regions. Almost all tutors enjoyed the programme and would recommend the experience to others. There was a relatively low dropout and the programme was warmly appreciated by participating primary schools. We have evidence that Valued Youth markedly raises confidence, improves communication skills and keeps some at risk youngsters on track in school. Many types of youngsters benefit from the experience; those who lack confidence and have poor communication skills seem to make the most progress. Successful tutors tend to be those who are committed to the programme, willing to learn, are flexible and cooperative, and have some ability to interact with others, particularly children and primary teachers.</p

Russian archives and archivists in a time of troubles

This presentation addressed the author's observations of various archival institutions, meetings with archival administrators, and conversations with host archivists during a visit to Russian and Polish archives in October and November 1995

Adding Electronic Records to the Archival Menagerie: Appraisal Concerns and Cautions

Electronic records are significantly different from most of the records held in institutional archives and, thus, they must be appraised and evaluated for accessioning with different and additional factors in mind. The archival predilection for discussing electronic records only within the context of preservation issues fosters the misconception that--given optimum environmental conditions--electronic media may be considered an archival or long-term storage format. This is not a realistic assessment. Electronic media should be approached as a transitory information format in the archives. The mistaken beliefs that electronic recording formats are long-term storage media and that the readily apparent and sometimes superficial advantages of the volume-to-data ratio of electronic records when compared to other formats have led to the excessive accessioning of machine-readable records into some institutional archives with inadequate reasons to justify the transfer

The Impact of Counselor Level of Spiritual Well-Being on the Morale, Global Symptoms, and Global Impairment of Adolescents Receiving Treatment for Substance Use and/or Other Mental Health Disorders: A Pilot Study

In recent years there has been a movement towards a holistic perspective of human nature in the counseling leading to increased interest in the nature and role of spirituality in counseling and the counseling process. In the present study multiple regression analysis is used to determine whether Counselor Level of Spiritual Well-Being, or aspects thereof, namely, Counselor Level of Existential Well-Being and/or Counselor Level of Religious Well-Being, as measured by the Spiritual Well-Being Scale significantly impacts client outcomes, namely, Morale, Global Symptoms, and Global Impairment as measured by the Health Dynamics Inventory for adolescents receiving treatment for substance use and/or co-occurring psychiatric disorders. A significant relationship was found for only Counselor Level of Religious Well-Being alone and in combination with other variables and client outcomes on Global Impairment. Results and their implications as well as suggestions for further research are discussed
