“…During a personal interview at participants' homes in 1999, the current use of pharmaceutical preparations containing vitamins and minerals or food supplements was reported by 23% (30.5% of the women and 15.3% of the men) of the population investigated in the SENECA study [15] . The percentage of supplement users in our study is in accordance with results from some recent US and Australian studies in elderly populations [16,17] . In the Third National Health and Nutrition Examination Survey (NHANES III) 51.6% of women and 39.3% of men aged 60-69 years as well as 54.4% of women and 40.5% of men aged 70 years and over reported vitamin and mineral supplement use in the month before the investigation [18] .…”

Aim: To assess the prevalence of vitamin and mineral supplement use in a free-living elderly population and the contribution of these supplements to usual dietary intake. Methods: Analyses are based on data obtained from 388 subjects (≧60 years) participating in the longitudinal study on nutrition and health status in an ageing population in Giessen (GISELA), Germany, in 2002. Nutrient intake from food was assessed by means of a 3-day estimated dietary record. Supplement use was recorded over a period of 3 days using a self-administered questionnaire. Results: Nearly half of the study population consumed at least 1 supplement within these 3 days. The use of supplements was more prevalent among women than among men (51.5 vs. 33.9%). On average women consumed 2.03 ± 1.30 products and men 1.65 ± 1.07 products. Magnesium, vitamin C and vitamin E were supplemented most often by men, while women supplemented magnesium, vitamin E and calcium most often. Most of the supplemented nutrients did not distinctly increase the average intake of the respective nutrients from the diet in this population. However, supplement use markedly decreased the proportions of elderly subjects with an intake below the current reference values for certain nutrients, particularly for vitamin E. Conclusion: Results indicate that the intake of supplements is a common behavior in the population under investigation and therefore has to be considered when nutrient intake is evaluated.

“…In June and July 1985, 3000 Adelaide residents aged 65 years and over were randomly selected from the South Australian State electoral rolls, and invited to participate in a study of dietary intake and associated physical, behavioural and socioeconomic factors in old age (Horwath, 1989b,c,d,e,f;Horwath & Worsley, 1989). Questionnaires were administered by mail, and up to three reminders were sent to non-responders at two-weekly intervals after initial mailing, resulting in a response rate of 77 per cent (n = 2195), after allowing for deaths and confirmed nondeliveries.…”

Dietary Changes Reported by a Random Sample of Elderly People

A random sub-sample of 153 elderly people was followed up 18 months after a large-scale random dietary survey of adults aged 65 years and over residing in Adelaide, South Australia. The follow-up questionnaire examined self-reported dietary and weight change over the 18 month period since the original study. The same semi-quantitative food frequency questionnaire as used in the initial survey was also repeated. Challenging the common stereotype of rigidity and resistance to change in elderly people, a high degree of dietary change was reported since the original study (67% of men and 68% of women reported a change in diet), particularly among the 65-69 year age group (78%). The most commonly reported changes were largely in accord with dietary guidelines. Commonly reported changes included less frequent intake of red meat, eggs, fried and fatty foods and more frequent intake of vegetables, chicken and fish, as well as changes towards use of polyunsaturated margarine, no longer eating the fat on meat and no longer presoaking vegetables in water before cooking. Of concern was a change in some subjects to a less frequent consumption of milk or other dairy products.

“…Since then, five studies have examined the prevalence of supplement use among older Australians. One study used a self‐administered mail questionnaire to measure the use of 10 specified dietary supplements one month prior to survey in a randomly selected sample of 2195 Adelaide residents aged 65 years and over 2 . Another study conducted personal interviews and used a dietary history to study the diets and use of supplements in a group of 105 war veterans aged 60 years and over (interval of study not specified) 3 .…”

Objective: The aim of the present study was to measure the prevalence and patterns of dietary and health supplement utilisation of older Australians. Design: A self‐administered mail questionnaire. Subjects and setting: Almost 2500 Australians aged 65 years and over were randomly selected from the 2000 Australian Electoral Commission roll. All states and territories were proportionally represented in the sample. Responses were obtained from 1263 predominantly independently living Australians aged 65 years and over. Results: At the time of the survey, 43% (n = 548) reported the use of some form of supplement: females 52% (n = 324) and males 35% (n = 224). The supplements used most often were vitamin C (26%), multivitamin/mineral preparations (17%), fish oils (17%), vitamin E (16%), calcium (+/– vitamin D) (13%), garlic capsules or oil (11%), vitamin B (single or mixed) (9%), other single vitamins or minerals (7%), zinc (6%) and gingko (5%). The majority of supplements were consumed regularly (daily or every few days) and for an extended period (more than three years). Supplement users appeared to rely on their doctor, newspapers, family or friends and pharmacy staff for information about supplements. The most commonly cited reasons for supplement use were to enhance energy levels, improve stamina and promote feelings of wellness. Conclusion: A high proportion of older supplement users reported regular and prolonged patterns of supplement use. Health professionals should explore the motives that maintain this behaviour, evaluate the appropriateness of the type and patterns of supplement use and provide supplement users with information that explains the potential risks associated with commonly used supplements.
