“…These data suggest a low prevalence of Zn deficiency in free-living ageing European people. This low prevalence of Zn deficiency in a free-living elderly population confirms previous data from others studies which report prevalence at 5% in a study in Boston and 3-4% in EuronutSeneca European-based study (Bailey et al, 1997), but are very different from data reported in hospitalised elderly, in which 28% (Pepersack et al, 2001) or 38% had plasma Zn below the cutoff value of deficiency (Schmuck et al, 1996).…”

Objective: Inadequate intakes of micronutrients in elderly negatively affect the nutritional status. Zinc is an essential micronutrient in the elderly, especially in relation to its impact on immune function, bone mass, cognitive function and oxidative stress. However, data are lacking on zinc intake and status during normal ageing. In this study, we evaluate the intake and status of zinc in late middle-aged and older free-living subjects. Design: Dietary zinc intake and zinc status in 188 middle-aged subjects from Clermont-Ferrand (Fr) and Coleraine (UK), and in 199 older subjects from Grenoble (Fr) and Roma (It) were assessed at the entry in the ZENITH study. Results: In relation to the zinc RDA for people older than 55 y, zinc intakes in most of the middle-aged and older subjects (more than 96%) in the present study were adequate. Older people had significantly lower (Po0.01) energy intakes as compared to middle-aged. Zinc intake expressed per MJ was also significantly (Po0.01) higher in older people compared to middle-aged. Erythrocyte and urinary zinc concentrations were significantly (Po0.001) higher in middle-aged subjects compared to older ones. The prevalence of biological Zn deficiency in free-living ageing European people was low (o5%). Conclusion:The results of the present study showed a relatively low prevalence of zinc deficiencies in healthy free-living late middle-age and older subjects. These results should be useful for health professionals to have reference data on zinc intake and status for a healthy ageing.

“…This paradox has also been noted in other recent studies of older people in the UK (Bailey et al 1997;Madigan et al 1998). Table 3 lists mean values for the biochemical status indices where there were significant differences between free-living participants and those in institutions, and examines the percentage differences between these two population groups, adjusted for age (since there was a highly significant difference in age profile between the two groups) and for sex.…”

Micronutrients: highlights and research challenges from the 1994–5 National Diet and Nutrition Survey of people aged 65 years and over

The aims of the National Diet and Nutrition Survey series are summarized, and the new National Diet and Nutrition Survey of people aged 65 years and over is explored, with particular emphasis on micronutrient intakes and status indices. Mean nutrient intakes were generally satisfactory for most micronutrients, but intakes of vitamin D, Mg, K and Cu were low. Intakes of vitamin D were far below the reference nutrient intake for people aged 65 years and over, and there was also biochemical evidence of vitamin D deficiency, for 8 % of free-living and 37 % of institution participants, attributed partly to limited exposure to sunlight. A substantial proportion of people living in institutions had inadequate biochemical status indices, notably for vitamin C, Fe and folate. Relationships between intake and status were close for vitamins. Mineral intakes did not correlate well with currently used status indices. Some intakes and indices, especially those of vitamin C, carotenoids, Na and K, were strongly correlated with socio-economic status and with north-south gradients in Britain. Future research challenges should address the functional and health significance of low intakes and sub-optimal biochemical indices for certain micronutrients, especially for people living in institutions; the shortcomings of mineral status indices especially as indicators of mineral intake; the social and geographical inequalities of micronutrient intakes and status, and why micronutrient status deteriorates with increasing age. The answers to these questions will help to define the characteristics of nutritional risk for older people in Britain, and to clarify future needs for education and intervention. Micronutrients: National Diet and Nutrition Survey: ElderlyThe purpose of the present paper is to draw attention to the British Government's National Diet and Nutrition Survey of people aged 65 years and over, and the reports derived from it Steele et al. 1998). It also considers some of the problems of interpretation and research challenges of this large dataset in order to encourage other researchers to continue this investigation. The primary data from the survey will be lodged with the

“…Diversos estudios nacionales 19,30,31 , regionales 13,15 , otros países en vías de desarrollo 27 e incluso de países desarrollados 26,28,32,33 han mostrado una ingesta inadecuada de zinc en los adultos mayores, acentuándose la reducción de la ingesta con la edad 5 . Por otra parte, una ingesta insufi ciente de cobre en este grupo etario ha sido demostrada en estudios nacionales 19,29 y algunos realizados en países desarrollados 32,34 . En una muestra representativa de la población de Santiago, Chile, encontramos en adultos mayores de 60 años que 86,4% de los hombres y 57,9% de las mujeres tenía una ingesta de zinc menor al requerimiento promedio estimado de zinc, siendo esta frecuencia para el cobre de 7,7% en hombres y 21,1% en mujeres 19 .…”
