Substance use by indigenous and non-indigenous primary school students.

OBJECTIVE: Recent Australian research with adolescents aged 13 to 17 years has found that Indigenous youth are more likely than non-Indigenous adolescents to smoke tobacco and cannabis, although they may be less likely to use alcohol. The objective of this study was to examine whether this pattern exists among younger children. METHOD: A school-based, self-report survey was conducted in primary schools that had high proportions of Aboriginal and Torres Strait Islander children. Four schools were located in metropolitan Brisbane and three in Far North Queensland (sample n = 507 students: 270 girls, 237 boys, aged 9-13 years). RESULTS: Significant numbers of these children had started to experiment with recreational drugs. Twenty-two per cent had attempted to smoke at least one cigarette, 14% smoked in the preceding year, while 3% had smoked more than 10 cigarettes in their lives. Thirty-eight per cent had had at least one drink of alcohol, while 6% had smoked marijuana at least once. There was no significant association between Indigenous/non-Indigenous background and risk of smoking tobacco or marijuana, while Indigenous children were less likely than non-Indigenous children to report experience with alcohol. CONCLUSIONS: Contrary to data from secondary school students, Indigenous youth in primary schools were not more likely than non-Indigenous children to have experimented with tobacco or marijuana, or to be frequent tobacco smokers. It appears therefore that the excessive uptake of drug use among Indigenous youth occurs in the early stages of secondary school. This finding underlines the importance of preventive education in primary schools, especially for Indigenous children who have a high risk of making the transition to drug use in adolescence.

Predictors of hysterectomy: an Australian study.

OBJECTIVE: We evaluated the relative importance of predictors of hysterectomy. STUDY DESIGN: A questionnaire survey of an Australia-wide sample of adult female twins was conducted; self-report data were validated against reports from treating physicians. RESULTS: A total of 3096 women (94%) and 366 physicians (87%) responded. The sensitivity of patient report of hysterectomy was 98.2%. Best predictors of hysterectomy were endometriosis (odds ratio 4.85, 95% confidence interval 3.17-7.43), medical consultation for menorrhagia (odds ratio 3.55, 95% confidence interval 2.47-5.12), joint effects of fibroids with medical consultation for chronic or persisting pelvic pain (odds ratio 3.34, 95% confidence interval 1. 42 to 7.87), having smoked >40 cigarettes per day (odds ratio 3.24, 95% confidence interval 1.10-9.55), joint effects of fibroids with consultation for menstrual problems (odds ratio 2.61, 95% confidence interval 1.36-5.01), and tubal ligation (odds ratio 1.77, 95% confidence interval 1.31-2.39). Less-important predictors were age and higher education level (protective). CONCLUSION: Consulting a physician about pelvic pain and menstrual problems, especially heavy bleeding, are recognized steps toward hysterectomy. Of particular interest for future genetic analyses are the high odds of hysterectomy for women with endometriosis, fibroids, or menorrhagia.

The family physician and the "know your blood pressure by heart" education program.

Patient education is an important aspect of medical practice, especially in the realm of chronic diseases such as hypertension (HT). Family physicians are in an ideal position to engage in educational activities that promote the control of HT and reduce cardiovascular risk. The Canadian Heart Foundation has developed a series of educational activities for the purpose of creating awareness about the importance of blood pressure in cardiovascular health. This program-"Know Your Blood Pressure By Heart" (KYBPBH) -is based on the concepts of wellness and self-care, and is designed to increase the number of Canadians who know their blood pressure measurement. KYBPBH educational objectives, which are targeted to the middle-aged male, require active support by health professionals. This article describes the material resources available for KYBPBH and encourages family-physician involvement.
