Dietary intakes and vitamin status of a sample of homeless people in Paris

Abstract

OBJECTIVE: To determine nutritional intake and vitamin status in a sample of homeless people who had been on the streets of Paris for more than 2 y. DESIGN: The nutritional status was evaluated by a 24 h recall questionnaire and by assay of circulating levels of vitamins A, B 1 , B 6 , B 12 , C and E. SETTING: The study was conducted in four accommodation centres of the SAMU Social of Paris (CHUSI units) from July 1999 to May 2000. SUBJECTS: A total of 329 homeless people were interviewed. Only 87 subjects, aged 26 -76 y, were recruited based on seven selection criteria (over 18 y old, being homeless for more than 2 y, interviewed before taking a meal in the CHUSI units, good understanding of French, in a calm state, not coming from hospital or another CHUSI units, without any acute condition that might affect usual dietary habits), and completed the dietary questionnaire. Out of these 87, 71 agreed to blood sampling. RESULTS: In all 84% of the subjects declared that they drank alcoholic beverages regularly (175 AE 167 g=day of alcohol), and 75.5% of the subjects also declared that they smoked. The mean total energy intake was 2111 AE 1482 kcal=day for the men (8823.98 AE 6194.76 kJ=day) and 1523 AE 531 kcal=day for the women (6366.14 AE 2219.58 kJ=day). Alcohol accounted for 44 AE 30% and 19 AE 17% of the total energy intakes (TEI) for the men and women, respectively. Proteins, lipids and carbohydrates accounted for 21 AE 9, 23 AE 14 and 57 AE 16%, respectively, of the energy intake without alcohol for men, and 15 AE 5, 22 AE 11 and 62 AE 14% EIWA for women. For all micronutrients, except for iron in the men, more than 50% of the population studied had intakes below the French recommendations for the adult population. All the women had calcium, vitamin E and vitamin B 1 intakes below the recommendations for French women (900, 12 and 1.3 mg=day, respectively) in the general population. For the men, 98.7, 96.1 and 93.5% of the subjects had vitamin E, B 1 and C intakes below the recommendations for French males in the general population (12, 1.5 and 80 mg=day, respectively). It is of note that subjects who ate in the CHUSI units more than once a day per week had significantly (P ¼ 0.018) higher intakes of vitamin C (27 AE 38 mg=day) than did the subjects who ate in the CHUSI units less than once a day (8 AE 12 mg=day). Measurement of serum vitamin levels demonstrated a deficiency in 95% of the subjects, mainly for vitamin C. The mean concentration in serum was 16 AE 8 mmol=l, although 72% of the subjects had levels of 6 mmol=l. In contrast, 50.7, 42.2 and 35.2% of the subjects had high levels of vitamin B 6 , B 12 and B 1 , respectively (100 nmol=l, 420 pmol=l and 40 mmol=l). CONCLUSION: Alcohol takes a high place in the diet of these homeless people. Although the total energy intake was too low, macronutrient intakes seem to be satisfactory in quality (well-balanced). However, calcium and vitamin C intakes were too low, and these deficiencies favour the development of disease (scurvy, asthenia, ecchymosis), in ad...

Absence of protein-energy malnutrition in Prague homeless

“…Studies have reported that 20 %-44 % of the homeless are underweight and suffer from wasting malnutrition. The same studies go on to describe vitamin and mineral insuffi ciency, as indicated by low blood levels or based on intakes below the recommended daily allowances [2][3][4][5][6][7][8][9][10][11][12]. Only a few studies have documented the absence of undernutrition in homeless populations.…”

Nutritional and environmental considerations of food stockpiles in Japan and USA: reducing food waste by efficient reuse through the food banks

“…3.1 Survey method 3.1.1 Actual situation and activities of the food bank in the United States In the survey, 200 food banks were found to be currently active in the US according to the United States Department of Agriculture [8]. The philosophy behind each food bank establishment was examined to typify different organizations that can be considered food banks.…”

“…Japan-US comparison of food bank activities and the points for Japanese food banks to learn the activity in the United States Currently, there are 40 food banks in Japan and 200 or more in the United States [8]. There is a large population difference between the two, and in the United States, the Department of Agriculture is supporting the food bank activities by purchasing agricultural products from producers though there is no such system in Japan [2].…”

“…The actual situation in the US through the Internet research [8] was determined and analysis of the report published by Mitsubishi Research Institute [9].…”

“…Lack of intake of vitamins and minerals has also been noted as an issue in other countries [12][13][14]. In order to improve the nutritional status of the homeless population, sufficient amounts of vegetables and fruits must be provided.…”
