To highlight the value of continuous risk factor surveillance systems in providing evidence of the impact of, and to inform health promotion interventions.
An ongoing risk factor surveillance system involving telephone interviews with approximately n = 600 randomly selected South Australians each month. Trend analysis on physical activity (PA) levels and daily consumption of fruit and vegetables was undertaken.
An apparent seasonal trend for fruit consumption and PA was found, with less activity and fruit consumption undertaken in winter months. Overweight/obese adults exercised less than those with normal BMI, and females less than males, although PA rates for both females and overweight/obese adults are rising. There was an increase in vegetable consumption following a major media campaign. Although reported prevalence of the consumption of five or more serves of vegetables daily and the mean number of serves consumed daily has decreased, it is still above pre-campaign rates.
Additional information obtained from a risk factor surveillance system, when compared to an annual or point-in-time survey, provides valuable evidence for health professionals interested in measuring and assessing the effectiveness of health promotion interventions.
强调连续风险因素监测系统在提供影响证据和为健康促进干预提供信息方面的价值。
这是一个正在进行的风险因素监测系统，每月通过电话采访大约 600 名随机选择的南澳大利亚人。对身体活动（PA）水平和每日水果及蔬菜摄入量进行趋势分析。
发现水果消费和 PA 存在明显的季节性趋势，冬季活动和水果摄入量较少。超重/肥胖成年人的运动量低于 BMI 正常者，女性低于男性，尽管女性和超重/肥胖成年人的 PA 率正在上升。在一次重大媒体宣传活动后，蔬菜摄入量有所增加。尽管每日食用五份或更多份蔬菜的报告发生率和每日平均食用份数有所下降，但仍高于宣传活动前的水平。
与年度或时点调查相比，风险因素监测系统提供的额外信息为关注衡量和评估健康促进干预效果的健康专业人员提供了有价值的证据。
