Alcohol Use in a Community‐based Sample of Subjects Aged 70 Years and Older

The usual alcohol intake in a community‐based sample of subjects aged 70 years and over was investigated. A sample of 825 subjects was drawn from the records of five general practices in a rural township and 774 subjects (93.8%) agreed to participate. A stratified sub‐sample of subjects from the abstainers, infrequent, weekly, and daily drinkers was subsequently investigated in more detail. Men took alcohol more frequently than women and in greater quantities although frequency and amount decreased with age. The usual place for drinking was the home. The highest use of psychotropic drugs occurred in the abstainers, but this was significant for men only. When compared with drinking patterns in middle age, 60.1% of men and 30.3% of women said that they took less alcohol, while 7.4% of men and 11.1% of women said that they took more. The main reasons for decrease in alcohol intake were change in health and fewer social opportunities. The main reasons for increase in alcohol intake were more money and more time. Drinking was most commonly associated with social activities and few took alcohol to help cope with personal situations.

Factors influencing milk and milk product consumption in young and elderly women with low calcium intakes

Abstract The aim of this research was to investigate factors influencing milk and milk product consumption in young and elderly women consuming less than two-thirds of the RDA for calcium. Semi-structured, open-ended interviews were conducted with 71 women over 70 years and 22 women aged 19–23 years. Questions addressed changes in milk and milk product intake, and reasons for changes; perceptions of the likely effects of an increased intake of milk or milk products on health; reasons for low consumption of milk or milk products; and willingness to increase intake of various calcium-rich foods. The elderly low-calcium consumers were identified from a nutrition and health study of all people over 70 years residing in one New Zealand town. The young women were low-calcium consumers identified from a university class of nutrition students. Older women were most likely to perceive that increasing their milk or milk product intake would have either no effect on their health or adverse effects on conditions such as diabetes, high blood cholesterol or blood pressure, and heart problems. Although young women were more likely to perceive potential health benefits from consuming more milk (and to a lesser extent milk products), an increase in body weight was the reason given by all those who believed an increased intake would be bad for them. Some 13–18% of women had been advised by doctors to eliminate milk or milk products from their diet, usually for inappropriate reasons. For both age groups, dislike was the most important reason for not consuming more milk; however health concerns were the primary reason for not consuming more of the other dairy products. There is need to actively counter misconceptions amongst both women (particularly elderly women) and doctors, concerning adverse effects of milk or milk products on health conditions. For young women, emphasis is needed that weight control does not require the exclusion of milk or milk products from the diet. Programs are required to increase awareness of the wide range of low-fat milks and milk products now available, and of the potential benefits of these for bone health.

Dietary survey of an elderly New Zealand population

Caroline C. Horwath; A. John Campbell; Wendy J. Busby

Abstract Mean daily energy and nutrient intakes were estimated in a community based sample of 712 people aged 70 years and over in Mosgiel, New Zealand, by means of a semi-quantitative food frequency questionnaire. The study population included all those people in this age group who were registered with the Mosgiel Health Center. Eighty five per cent agreed to participate in the dietary part of a detailed multidisciplinary study of nutrition and health in old age. Mean intakes of most nutrients were above the recommended levels; the only exceptions were low mean intakes of zinc and copper, and, among women only, a low mean calcium intake. The proportion of people with intakes below two thirds of the recommended levels was highest for zinc, copper, calcium and magnesium. In several ways the food choices of women appeared to be healthier than those of men; however, in terms of nutrient intakes, the main effect of this was a higher nutrient density in women for a small number of micronutrients.

Why Nosokinetics? Measuring and Modelling the Process of Care

Peter H. Millard; Brendon Rae; Wendy J. Busby

Mistakes are being made in the planning of services to meet the needs of an aging population because the tools used to measure and model clinical care services give incomplete, misleading information about the process of care. Beds are important in geriatric medicine and the distinction between short and long stay care is clear. This paper first describes the biological model developed following quantitative analysis of bed occupancy and use in a 16 year data set, collected between 1969-1984 in the St, George’s Hospital, London, department of geriatric medicine, and its clinical equivalent. Then we explain the clinical and organizational changes in the process of care in a general medical department at Dunedin Hospital, New Zealand, which solved and created bed crises. “Modelers beware” changing clinical services is not as simple as it sounds.

Streptococcus Bovis Infection of the Pulmonary Valve in an Elderly Woman With a Colonic Polyp

Wendy J. Busby; A. J. Campbell; C. D. J. Ilsley

nfective endocarditis affecting the right side of the heart alone is rare, accounting for 5% or less of all cases.*** When this occurs, the tricuspid I valve is usually involved and usually in association with predisposing factors such as intravenous drug use, alcoholism, and immunosuppression.3 Staphylococcus aureus and fungi are the most common infecting organisms. We report a case of a previously healthy 81-yearold woman with streptococcus bovis endocarditis of the pulmonary valve, a large bowel polyp and sideroblastic anemia.

Prescribing cardiovascular drugs for elderly patients.

Wendy J. Busby; A. John Campbell

Cardiovascular disease is common in old age. Cardiovascular drugs are widely used, usually with considerably more benefit than harm. But adverse effects do arise and measures can be used to increase tolerability. More than 50% of deaths in people aged 65 years and over are due to cardiovascular disease, mostly ischaemic heart disease. In a recent community study of people aged 70 years and over living in Mosgiel, New Zealand, we found 7.5% had symptoms of angina, 12% gave a history of myocardial infarction and, depending on the strictness of the criteria used, 5 to 25% of people had ECG evidence of ischaemic damage (Busby et a1. 1994). These prevalence rates are very similar to those in other developed countries (Mittelmark et a1. 1993). Studies of prescribing patterns in New Zealand show that around one-third of elderly people take a diuretic, 10 to 20% take digoxin and 40 to 50% take at least one drug liable to cause postural hypotension. These proportions are similar to those described in other countries (Laukkanen et al. 1992). Careful individual consideration is always needed when prescribing for elderly people. Older people vary considerably in the drug dosage required, and tolerance of adverse effects is diminished. Heterogeneity increases and homeostasis decreases. A more general discussion of drug prescribing for older people is provided by Montamat and colleagues (1989). There are consequently a number of issues which need to be considered on initiation and during maintenance of therapy. We suggest a number of questions worth considering when prescribing cardiovascular drugs for old people.
