Relationship between the number of partners in a general practice and the number of different drugs prescribed by that practice.

The objective of this study was to assess whether practice size, as measured by the number of doctors, had any bearing on the range of drugs prescribed. All practices in the northern and western health boards in Northern Ireland were included in the study--a total of 132 practices (362 doctors) serving a population of 628,249. Prescribing data, obtained from the Department of Health and Social Services (Northern Ireland) information technology unit database, were analysed retrospectively for the month of January 1989. The number of different preparations prescribed in each of 22 therapeutic groups were counted. Hence a measure of the range of prescribing was assessed. A significant correlation was found between the number of different preparations prescribed and the number of general practitioners working in the practice. However, no correlation was found between the number of different drugs prescribed and the mean prescribing cost per patient or the mean list size of the doctors in each practice. The use of a practice prescribing policy was found to have no influence on the range of drugs prescribed, nor on the prescribing costs. The inference is that formal therapeutic policies may be difficult to implement within group practices. These results are of importance to general practitioners since the greater the number of different drugs prescribed the greater will be the risk of side effects and dangerous interactions.

Study of coronary risk factors related to physical activity in 15 171 men.

Physical activity, both at work and during leisure, was assessed in 15 171 men aged 25-74 years. Heavy leisure activity was associated with lower mean serum cholesterol levels and blood pressure. In men under 60 years the same negative association was also noted between leisure activity and relative weight and cigarette smoking. Different degrees of physical activity at work were not associated with any differences in these risk factors, nor did the level of exercise at work seem to influence the negative association between leisure activity and risk factors. Heavy leisure activity in young and middle-aged men is associated with lower levels of certain coronary risk factors and, therefore, a lower risk of coronary heart disease. The often-reported reduction in coronary morbidity and mortality with physical exercise may not be the direct effect of the exercise itself.

A study of breast cancer in Irish women.

In a study of 100 women with breast cancer and 200 unaffected women the epidemiological characteristic of breast cancer most commonly described--namely, an excess of nonparous women among cases when compared with controls, was not observed. It is suggested that two factors, a dearth of first births born to mothers under 20 years of age and an unusually high proportion of first births when aged 30 years or more, are responsible for this finding. No association was found between breast cancer and socioeconomic status, marital status, age at marriage, age at first pregnancy, parity, or age at menarche. Significant associations with breast cancer included age at natural menopause, hysterectomy, and breast trauma. These findings are discussed.
