The variation of concentrations of immunoglobulins and albumin in consecutive daily collections of saliva was studied in 33 infants, aged 6 months to 5 years, for periods ranging from 16 to 26 days. The concentration and the within-child variability of IgA and albumin and the detection of IgG and IgM in saliva increased with age. Between-child variances(More)
Objective: Whole-body skin self-examination (SSE) with presentation of suspicious lesions to a physician may improve early detection of melanoma. The aim of this study was to establish the prevalence and determinants of SSE in a high-risk population in preparation for a community-based randomised controlled trial of screening for melanoma. Methods: A(More)
To investigate the prevalence of food insufficiency and factors associated with it, two questions assessing household and individual food insufficiency were included in 13 regional health surveys conducted in Queensland in 1993. The surveys used computer-assisted telephone interviewing methodology. Of the 10,451 people interviewed, 9.7 per cent and 6.4 per(More)
After the creation of thirteen health regions within Queensland in 1991, the need arose for an information base at the regional level to assist regions with their role in planning, monitoring and evaluating health services. A series of regional health surveys was conducted in 1993 to provide this information, using a computer-assisted telephone interviewing(More)
OBJECTIVES Melanoma is a significant cause of morbidity and mortality worldwide and incidence is increasing. Survival after treatment is inversely related to the thickness of the tumour at diagnosis. Population screening has the potential to reduce mortality but there is no conclusive evidence of benefit. Such evidence can come best from a randomised trial.(More)
OBJECTIVE To establish the prevalence and predictors of skin screening by general practitioners in regional Queensland. DESIGN Questionnaire administered to participants by professional interviewers via telephone. PARTICIPANTS AND SETTING Participants were 3100 adults aged > or = 30 years (66.9% overall response rate), selected from residents of 18(More)
Screening by whole-body clinical skin examination may improve early diagnosis of melanoma and reduce mortality, but objective scientific evidence of this is lacking. As part of a randomized controlled trial of population screening for melanoma in Queensland, Australia, the authors assessed the validity of self-reported history of whole-body skin examination(More)
Mortality rates from all causes in Maoris in New Zealand and Native Americans have fallen substantially since the early 1970s. Comparable mortality rates for Australian Aboriginals and Torres Strait Islanders in 1990-1994 were at or above the rates observed 20 years ago in Maoris and Native Americans, being 1.9 times the rate in Maoris, 2.4 times the rate(More)
The Rand Corporation medical outcomes short-form 36 health survey (SF-36) is a multidimensional measure of self-perceived general health status, which has been validated in adult populations in the United States and Great Britain, and, more recently, in an Australian population. The SF-36 is increasingly being used in health outcomes research(More)
BACKGROUND Patient, physician, and consultation variables associated with overweight and smoking counseling in general practice consultations were examined. METHODS A random sample of full-time general practitioners was used. The sample consisted of 7,160 patients from 230 GPs who attended for consultations on consecutive days, and self-reported(More)
