THE PERCEPTION AND UNDERSTANDING OF HEALTH PROFESSIONALS AND UNDERGRADUATE STUDENTS REGARDING AGING AND THE ELDERLY

This qualitative study was developed with 117 healthcare professionals and undergraduate students who were participants of a non-verbal communication training program in gerontology, with the objective to identify the perception and understanding of healthcare undergraduates and graduates regarding aging and the elderly. The results allowed the construction of the following categories: an evolution of life that brings a variety of experiences; natural, mysterious and with accumulated experiences; a decrease in overall happiness due to an increase in isolation; a time of valuing affection and respect; an inevitable stage including distress, prejudice, and limitations worthy of attention; a natural consequence of life; and the presence of disease and the global physiological process. Regarding perceptions of the elderly, the answers were classified as positive, negative, mixed and neutral. We considered that the understanding regarding the elderly and aging was limited and pessimist, indicating a need to become aware that one's views affect the way we relate to others.

Validation of a FFQ for estimating omega-3, omega-6 and trans fatty acid intake during pregnancy using mature breast milk and food recalls

BACKGROUND/OBJECTIVES: To assess the performance of a food frequency questionnaire (FFQ) for estimating omega-3, omega-6 and trans fatty acid intake during pregnancy. Moreover, we determined whether the fatty acid composition of mature breast milk represents a valuable biomarker for fatty acid intake during pregnancy. SUBJECTS/METHODS: A prospective study in 41 pregnant women, aged 18-35 years, was conducted. Food intake during pregnancy was evaluated by three 24-h recalls (24 hR), and 2 FFQ. The fatty acid composition of mature breast milk was determined by gas chromatography. The method of triads and joint classification between quartiles of intake were applied. RESULTS: The FFQ was accurate for estimating docosahexanoic (DHA), linoleic and total omega-6 fatty acids according to validity coefficients. Higher agreements (>70%) into the same or adjacent quartiles between the dietary methods were found for alpha-linolenic, total omega-3, linoleic and trans fatty acid intake. High validity coefficients for eicosapentanoic (EPA) and DHA acids of human milk were found (0.61 and 0.73, respectively), and the method was adequate for categorizing the intake of alpha-linolenic, total omega-3 and trans fatty acids compared with FFQ estimates, and for arachidonic acid and trans fatty acids compared with food recall estimates, during pregnancy. CONCLUSIONS: The FFQ was an accurate tool for categorizing alpha-linolenic, total omega-3 and trans fatty acid intake. According to the validity coefficients observed, the FFQ accurately estimated DHA, linoleic and total omega-6 fatty acids and the composition of mature breast milk was shown to be a suitable biomarker for EPA and DHA fatty acid intake during pregnancy.

Quality of diet of working college students

Considering the scarcity of studies with young workers and the role of diet in the prevention of chronic diseases, the objective of the study was to assess the quality of diet of working college students. The present study investigated 43 university students, aged between 18 and 25 years old who had systematically being involved in a working activity in the past 6 months, paid or unpaid, at least 6 hours daily, five days a week. Dietary intake measured by seven dietary records covering every day of the week was used to calculate the Brazilian Healthy Eating Index Revised (B-HEIR). It was observed a low B-HEIR score (53.43,+/- 7.81) indicating a risk of a poor quality of diet, with high intake of sodium and sugar and low consumption of fruits and whole grains. This poor quality of diet can result in an inadequate nutritional status that may increase the risk of obesity and chronic diseases.
