Youth suicide in New South Wales: urban-rural trends.

OBJECTIVE: The study tested the hypotheses that (i) the rate of suicide by firearms among youth (aged 10-19 years) is increasing at a greater rate than rates of suicide by other methods; (ii) the rate of youth suicide in rural New South Wales is significantly higher than those in urban areas; and (iii) the increase in youth suicide by means of firearms is occurring at a greater rate in rural males aged 15-19 years than in other groups. DESIGN: Data were obtained from the NSW Office of the Australian Bureau of Statistics concerning 735 youth suicides in NSW between 1964 and 1988. These were reviewed for information concerning residential area and method of death. Five five-year periods were used, and rates were calculated with population figures obtained in the census years for the same age and sex group. RESULTS: From 1964 to 1988, suicide by firearms has risen most substantially, from 3.4 to 5.6 per 100,000 per year in 15-19-year-old males. There has also been a substantial increase in 15-19-year-old male suicides by hanging (0.7 to 3.4 per 100,000 per year). Poisoning suicides have declined among females and males in the past 15 years. Suicide rates in Sydney, Newcastle and Wollongong have remained stable. In rural cities, they have increased from 1.5 to 4.7 per 100,000 per year (F = 4.9, P less than 0.02) while in rural municipalities and shires they have increased from 1.3 to 6.4 (F = 14.6, P less than 0.0001). The suicide rate of 15-19-year-old males has shown a modest increase in Sydney and no change in Newcastle or Wollongong, but the rate for 15-19-year-old males in rural cities has more than doubled, from 5.1 to 12.5 (F = 7.7, P less than 0.003), while in rural municipalities and shires, the rate has increased more than fivefold, from 3.9 to 20.7 (F = 9.3, P less than 0.001). There has been no significant change in the suicide rates of 15-19-year-old females, or in 10-14-year-olds. The rate of suicide by firearms among 15-19-year-old males has not risen significantly in rural cities, but in rural municipalities and shires the rates have risen fivefold from 2.8 to 14.8 (F = 5.6, P less than 0.01). CONCLUSIONS: Each hypothesis was confirmed. An increase of this magnitude is not an artefact of coroners' verdicts. The findings are believed to be due to ready access to firearms, the use of alcohol and drugs (particularly in firearms suicides) and increasing socioeconomic, health, and identity problems for rural youth, especially males.     

Remoteness of residence and survival from cancer in New South Wales

OBJECTIVE: To analyse cancer survival in New South Wales by geographic remoteness. DESIGN, SETTING AND PARTICIPANTS: A survival analysis of all patients with cancers diagnosed in NSW between 1 January 1992 and 31 December 1996. Survival was determined to 31 December 1999. MAIN OUTCOME MEASURES: The relative excess risk (RER) of death over 5 years was estimated for each geographic remoteness category relative to the highly accessible category for 20 cancer types adjusted for age, sex, years since diagnosis and, subsequently, stage of cancer at diagnosis. RESULTS: There were statistically significant differences in the RER of death across remoteness categories (P < 0.001) for cancers of the cervix and prostate and for all cancers. The RERs for the most remote categories (compared with the highly accessible category) before and after adjustment for stage were cervix, 3.22 (95% CI, 1.54-6.75) and 2.25 (95% CI, 1.06-4.77); prostate, 3.38 (95% CI, 2.21-5.16) and 2.53 (95% CI, 1.60-4.01); all cancers, 1.35 (95% CI, 1.20-1.51) and 1.25 (95% CI, 1.11-1.41). In addition, there were significant variations in RER of death by remoteness for head and neck, lung and colon cancers and cutaneous melanoma. CONCLUSION: Cancer survival varies by remoteness of residence in NSW for all cancers together and some cancers individually. Access to screening or early diagnosis probably contributes to this variation, but persistence after adjustment for stage suggests that treatment variation is also important.     

Tuberculosis in New South Wales

Surveillance of tuberculosis in New South Wales depends on notification of cases by medical practitioners and careful follow-up by public health nurses dedicated to the control of tuberculosis. Evaluation of tuberculosis surveillance data enables identification of patterns of infection, highlighting areas requiring specific interventions. In 1986, 290 cases of tuberculosis were notified to the Department of Health, New South Wales. The majority of patients (72.8%) were diagnosed as having pulmonary disease. The highest rates of infection were in people from Southeast Asian countries. Whereas 5.2% of cases were identified when the patients entered Australia, a substantial proportion of diagnoses (23.1%) were made in people who had been resident in Australia for 10 or more years. This article highlights the need to continue efforts to improve tuberculosis surveillance and control programmes in New South Wales.     

The cost of asthma in New South Wales

OBJECTIVE: To determine the economic cost of asthma to the New South Wales community. DESIGN: Direct costs (both health-care and non-health-care) plus indirect costs (loss of productivity) were estimated from various sources to assess retrospectively the dollar costs of asthma. Intangible costs (such as quality of life) were not included. SETTING: Estimates of costs were made at all levels of medical care of asthma patients, including inpatient and outpatient hospitalisations, emergency department visits, and visits to general practitioners and specialist physicians, plus costs of pharmaceuticals, nebulisers and home peak-flow monitoring devices. The cost of time lost by the patient attending for medical visits and loss of productivity due to absence from employment as a result of asthma were also included. RESULTS: The total cost of asthma in New South Wales was $209 million in 1989. This was made up of $142 million in direct health-care costs, $19 million in direct non-health-care costs and $48 million in indirect costs. CONCLUSION: Although we believe that our estimate is an underestimate of the true dollar cost of this disease to the community, it represents $769 per asthmatic person per year, assuming a current prevalence rate for asthma in New South Wales of 6%. The cost effectiveness of any new treatment of asthma should be estimated to ensure that the economic cost to the community does not rise unnecessarily.
