Health aspects, nutrition and physical characteristics in matched samples of institutionalized vegetarian and non-vegetarian elderly (> 65yrs)

<p>Abstract</p> <p>Background</p> <p>Epidemiological studies indicate that a well balanced vegetarian diet offers several health benefits including a lower prevalence of prosperity diseases in vegetarians compared to omnivores. It was the purpose of the present study to compare nutritional and physical characteristics in matched samples of institutionalized vegetarian (V) and non-vegetarian (NV) elderly.</p> <p>Methods</p> <p>Twenty-two female and 7 male V (females: 84.1 ± 5.1yrs, males: 80.5 ± 7.5yrs) and 23 female and 7 male NV (females: 84.3 ± 5.0yrs, males: 80.6 ± 7.3yrs) participated. All subjects were over 65 years of age, and free of major disease or physical handicap. Dietary intake, blood profile, anthropometrics, and handgrip strength were determined.</p> <p>Results</p> <p>Mean daily energy intake was 6.8 ± 2.0MJ in V females, and 8.0 ± 1.4MJ in the NV females, only the V did not reach the recommended value of 7.8 MJ. Male V and NV had a mean daily energy intake of 8.7 ± 1.6MJ and 8.7 ± 1.2MJ respectively (RDI: 8.8 MJ). Mean carbohydrate intake was significantly below the RDI in NV only (female V: 47.8 ± 7.5E%, female NV: 43.3 ± 4.6E%, male V: 48.1 ± 6.4E%, male NV: 42.3 ± 3.6E%), while protein (female V: 17.3 ± 3.4E%, female NV: 19.5 ± 3.5E%, male V: 17.8 ± 3.4E%, male NV: 21.0 ± 2.0E%), and saturated fat intake (female V: 25.4 ± 8.2 g/day, female NV: 32.2 ± 6.9 g/day, male V: 31.4 ± 12.9 g/day, male NV: 33.4 ± 4.7 g/day) were too high in both V and NV. Mean micronutrient intakes met the RDI's in all 4 groups. Mean blood concentrations for vitamin B12, folic acid, iron, and calcium were normal in all 4 groups. Mean zinc blood serum was below the reference value in all groups, whereas estimated zinc intake was in agreement with the RDI. The mean blood cholesterol concentration was above the 200 mg/dl upper limit in the V group (213 ± 40 mg/dl) and below that limit in the NV (188 ± 33 mg/dl) group. Mean BMI was 26.1 ± 4.7 kg/m²in the female V, 26.8 ± 3.7 kg/m²in the female NV, 23.5 ± 3.7 kg/m²in the male V, and 25.2 ± 4.2 kg/m²in the male NV. V and NV scored below the reference values for the handgrip strength test.</p> <p>Conclusions</p> <p>Generally, our results show a similar profile for V and NV concerning dietary intake, blood values, and physical characteristics. Attention should be paid to the intake of mono- and disaccharides and saturated fats in the diet of both V and NV. This study indicates that a vegetarian lifestyle has no negative impact on the health status at older age.</p

Breakfast frequency and fruit and vegetable consumption in Belgian adolescents a cross-sectional study

Purpose - Several cross-sectional studies reported that breakfast skipping and a poor consumption of fruits and vegetables are associated with overweight and obesity-related morbidities. In this respect healthy eating habits such as regular breakfast and a sufficient intake of fruit and vegetables are two important items to prevent childhood and adolescent obesity. The purpose of this study is to determine the breakfast frequency and the fruit and vegetable consumption in Belgian adolescents. Design/methodology/approach - A cross-sectional study using pupils contacted by nurses in schools during an information session about female hygiene. On that occasion all pupils (boys and girls) completed a questionnaire concerning their eating habits. Subjects were boys (n=1390) and girls (n=3610) between 12 and 15 years of age from the main three educational programmes (general, technical and occupational programme). Findings - Socio-economic status significantly influenced breakfast frequency with differences between the highest educational programme (general) and the lower technical- and occupational programmes. The use of daily breakfast was respectively 67 versus 49 and 48 per cent for the boys and 60 versus 42 and 39 per cent for the girls). For both sexes breakfast frequency decreased when comparing age groups from 12 with 15 years of age respectively from 67 to 55 per cent for the boys and from 61 to 47 per cent for the girls. Half of the subjects who declared to have overweight (self-image) did not take breakfast at a regular base. Twenty six per cent of the boys of the French speaking part and 19 per cent of the boys of the Flemish speaking part of Belgium declared to take only one or less than one portion of fruit and/or vegetables a day. For the girls the reported intake of one or less than one portion of fruit and/or vegetables was respectively 20 and 16 per cent. Only 13 per cent of the French speaking boys and 10 per cent of the Flemish speaking boys reported an intake of four or more fruits and/or vegetables a day. The percentage of girls reaching an intake of four or more a day was 15 per cent for the two language regions. Fruit and/or vegetable intake was influenced significantly by the educational programme and by the educational level of the mother. In conclusion, healthy eating habits among girls and boys in Belgium (as estimated by breakfast frequency and fruit and/or vegetable intake) are rather poor. These habits are influenced by age, educational programme, self-image and educational level of the mother. Originality/value - In the light of these findings action should be taken to improve the eating habits among Belgian children to prevent childhood obesity.SCOPUS: ar.jinfo:eu-repo/semantics/publishe
