The Queensland preventive health survey is conducted annually to monitor the prevalence of behavioural risk factors in the north-east Australian state. Prompted by domestic and international trends in mobile telephone usage, the 2015 survey incorporated both mobile and landline telephone numbers from a list-based sampling frame. Estimates for landline-accessible and mobile-only respondents are compared to assess potential bias in landline-only surveys in the context of public health surveillance. Significant differences were found in subcategories of all health prevalence estimates considered (alcohol consumption, body mass index, smoking, and physical activity) from 2015 survey results. Results from Australian and international studies that have considered mobile telephone non-coverage bias are also summarised and discussed. We find that adjusting for sampling biases of telephone surveys by weighting does not fully compensate for the differences in prevalence estimates. However, predicted trends from previous years' surveys only differ significantly for the 2015 prevalence estimates of alcohol consumption. We conclude that the inclusion of mobile telephones into standard telephones surveys is important for obtaining valid, reliable and representative data to reduce bias in health prevalence estimates. Importantly, unlike some international experiences, the addition of mobiles telephones into the Queensland preventive health survey occurred before population trends were significantly affected.
昆士兰预防性健康调查每年开展一次，以监测澳大利亚东北部该州行为风险因素的流行情况。受国内外移动电话使用趋势的推动，2015年的调查纳入了基于列表抽样框架的移动电话号码和固定电话号码。对可通过固定电话联系的受访者和仅使用移动电话的受访者的估计数据进行比较，以评估在公共卫生监测背景下仅使用固定电话进行调查时的潜在偏差。从2015年调查结果来看，在所有考虑的健康流行率估计子类别（饮酒、体重指数、吸烟和体育活动）中均发现了显著差异。还总结并讨论了考虑移动电话未覆盖偏差的澳大利亚和国际研究结果。我们发现，通过加权调整电话调查的抽样偏差并不能完全弥补流行率估计值的差异。然而，仅2015年饮酒流行率估计值与前几年调查的预测趋势存在显著差异。我们得出结论，将移动电话纳入标准电话调查对于获取有效、可靠和具有代表性的数据以减少健康流行率估计中的偏差非常重要。重要的是，与一些国际经验不同，在昆士兰预防性健康调查中纳入移动电话是在人口趋势受到显著影响之前进行的。
