To examine the potential impact on trends in reported adolescent sugar-sweetened beverage (SSB) consumption following the adult-targeted Western Australian (WA) LiveLighter "Sugary Drinks" campaign, which is a television-led healthy lifestyle promotion and education mass media campaign that aired in multiple bursts between July 2013 and December 2018.
Data were from a repeated cross-sectional survey of Australian secondary school students aged 12-17 years conducted nation-wide in 2009-2010 (n = 13 790 from 238 schools), 2012-2013 (n = 10 309 from 196 schools) and 2018 (n = 9102 from 104 schools).
Significant declines in high SSB consumption (≥4 cups/week) were observed between 2009-2010 and 2012-2013 among students in both WA (27.1% vs 20.3%; odds ratio [OR] = 0.65, 95% confidence interval [CI] = 0.50-0.84, P = .001) and all other states and territories combined (30.6% vs 21.4%; OR = 0.60, 95% CI = 0.53-0.68, P < .001). Compared to 2012-2013, the proportion of students in WA who reported high SSB consumption was significantly lower in 2018 (20.3% vs 9.6%; OR = 0.37, 95% CI = 0.21-0.65, P = .001), whereas this significant decrease was not observed in all other states and territories combined (21.4% vs 17.8%; OR = 0.81, 95% CI = 0.67-0.97, P = .024). Interaction testing indicated that the recent decline observed in WA was more pronounced among female than male students.
Mass media campaigns targeted towards the Australian adult population may have favourable effects among adolescents with the steeper decline in high SSB consumption observed in WA between 2012-2013 and 2018 coinciding with the repeated airing of the LiveLighter "Sugary Drinks" campaign in this state. SO WHAT?: Government investment in mass media campaigns may hasten declines in adolescents' SSB consumption.
为了研究西澳大利亚州（WA）以成年人为目标的“含糖饮料”LiveLighter 活动对青少年报告的含糖饮料（SSB）消费趋势的潜在影响，该活动是一个以电视为主导的健康生活方式促进和教育大众媒体活动，于 2013 年 7 月至 2018 年 12 月期间多次播出。
数据来自于 2009-2010 年（来自 238 所学校的 13790 名年龄在 12-17 岁的澳大利亚中学生）、2012-2013 年（来自 196 所学校的 10309 名学生）和 2018 年（来自 104 所学校的 9102 名学生）全国范围内进行的澳大利亚中学生重复横断面调查。
在 WA 和所有其他州和地区的学生中，与 2009-2010 年相比，2012-2013 年高 SSB 消费（≥4 杯/周）显著下降（27.1% vs 20.3%；优势比 [OR] = 0.65，95%置信区间 [CI] = 0.50-0.84，P = 0.001）。与 2012-2013 年相比，WA 报告高 SSB 消费的学生比例在 2018 年显著降低（20.3% vs 9.6%；OR = 0.37，95% CI = 0.21-0.65，P = 0.001），而在所有其他州和地区则没有观察到这种显著下降（21.4% vs 17.8%；OR = 0.81，95% CI = 0.67-0.97，P = 0.024）。交互检验表明，在 WA，最近观察到的下降在女性学生中更为明显。
针对澳大利亚成年人的大众媒体活动可能对青少年产生有利影响，WA 州在 2012-2013 年至 2018 年间高 SSB 消费的急剧下降与 LiveLighter“含糖饮料”活动在该州的多次播出相吻合。
所以呢？政府对大众媒体活动的投资可能会加速青少年 SSB 消费的下降。
