Pre-Survey Text Messages (SMS) Improve Participation Rate in an Australian Mobile Telephone Survey: An Experimental Study

Mobile telephone numbers are increasingly being included in household surveys samples. As approach letters cannot be sent because many do not have address details, alternatives approaches have been considered. This study assesses the effectiveness of sending a short message service (SMS) to a random sample of mobile telephone numbers to increase response rates. A simple random sample of 9000 Australian mobile telephone numbers: 4500 were randomly assigned to be sent a pre-notification SMS, and the remaining 4500 did not have a SMS sent. Adults aged 18 years and over, and currently in paid employment, were eligible to participate. American Association for Public Opinion Research formulas were used to calculated response cooperation and refusal rates. Response and cooperation rate were higher for the SMS groups (12.4% and 28.6% respectively) than the group with no SMS (7.7% and 16.0%). Refusal rates were lower for the SMS group (27.3%) than the group with no SMS (35.9%). When asked, 85.8% of the pre-notification group indicated they remembered receiving a SMS about the study. Sending a pre-notification SMS is effective in improving participation in population-based surveys. Response rates were increased by 60% and cooperation rates by 79%

Representative population health surveys : improving public health through rigour, diversity of methods and collaboration

Prevention and slowing the progression, of chronic diseases ( such as cancer, heart disease, arthritis, diabetes, asthma, osteoporosis, dementia and incontinence ), and influencing risk factors and health behaviours of a population, relies on the best available data - driven evidence. The quality of measurement techniques to collect representative population health survey and surveillance data is, as a consequence, brought under scrutiny. The presentation of this thesis is the culmination of 17 years work that has been focused on contributing to improving public health in South Australia. It is premised on the understanding that continual epidemiological assessment using representative population health surveys can deliver evidence - based information needed by health policy makers, health planners and health promoters to make appropriate, timely and efficient evidence - based decisions. The objective of the portfolio of published papers was to demonstrate the contribution to producing quality data - driven evidence using population surveys through rigour in collecting self - reported data, diversifying surveillance data collection methods and facilitating collaboration. This portfolio presents papers that have addressed a range of methodological and chronic disease and risk factor epidemiological issues. In terms of demonstrating rigour the publications have addressed the bias associated with non - response, the methodological rigour inherent in face - to - face surveys, the differences in estimates that can occur based on mode of administration, the science of telephone surveying and the importance of good questionnaire design to produce valid and meaningful data. The literature presented has also demonstrated the first South Australian population - wide prevalence survey dealing with the consequences of domestic violence and associated issues ( for males and females ) in the community, and in doing so, demonstrated the use of the telephone to collect large - scale data in Australia on domestic violence and associated factors in the population. In addition, the first time the importance of undertaking an array of methodological precautions during the data collection phase associated with collecting data on sensitive health issues on the telephone was demonstrated in Australia as was the assessment of the bias obtained in health estimates dependent upon which telephone - based sample was used. In demonstrating the need for diversity in data collection the research submitted within this thesis has demonstrated the range of telephone surveying development issues and challenges in Australia and the benefits and the value of both face - to - face and telephone as survey data collection tools in Australia. The publications also made a significant contribution to the literature in the survey methodology area, in particular, within the systematic error in questionnaire design, the measurement error in BMI self - reported measurements, validity of self - reported height and weight, and the overall CATI methodology area. Epidemiological collaborative research in particular in the areas of social capital, HRT, mental health, suicide ideation, osteoporosis, interpersonal violence, chronic disease epidemiology and risk factor epidemiology was demonstrated. As a consequence of my research, surveying populations about their health is now entrenched into public health and health service sectors in SA. Rigour in collecting self - reported data, diversifying survey and surveillance data collection methods and facilitating collaboration, has produced quality date - driven evidence for South Australia.Thesis (Ph.D.)--University of Adelaide, School of Medicine, Discipline of Medicine, 2006

PUBLISHED VERSION Monosodium Glutamate Intake, Dietary Patterns and Asthma in Chinese Adults

Abstract Objectives: Emerging evidence shows that diet is related to asthma. The aim of this analysis was to investigate the association between monosodium glutamate (MSG) intake, overall dietary patterns and asthma. Methods: Data from 1486 Chinese men and women who participated in the Jiangsu Nutrition Study (JIN) were analyzed. In this study, MSG intake and dietary patterns were quantitatively assessed in 2002. Information on asthma history was collected during followed-up in 2007
