An independent evaluation of the Healthy Weight Commitment Foundation (HWCF) marketplace pledge found that the participating companies met and exceeded their interim 2012 sales reduction pledge.
This follow-up study conducted in 2013 used purchase data from 2000 to 2012 among U.S. households with children and compared trends in calorie purchases of HWCF, non-HWCF name brands, and private label (PL) products in the pre-pledge period (2000-2007) and the post-pledge period (2008-2012); controlled for potential effects of concurrent changes in demographic and economic factors, including the Great Recession and food prices; and assessed whether the HWCF marketplace pledge was associated with reductions in consumer packaged goods (CPG) calorie purchases by households with children.
There has been a significant per capita decline in average daily CPG caloric purchases between 2000 and 2012 among households with children from all brand categories. Based on pre-pledge trends, declines in CPG caloric purchases were already occurring. However, post-pledge reductions in calories purchased from HWCF brands were less than expected, and reductions in calories purchased from non-HWCF name brands and PLs were greater than expected after economic, sociodemographic, and secular factors were accounted for.
If the 16 HWCF companies had been able to maintain their pre-pledge trajectory, there should have been an additional 42 kcal/capita/day reduction in calories purchased from HWCF products in 2012 among households with children. A lack of change in total CPG calories purchased between 2011 and 2012 calls into question the sustainability of the decline and a need for continued monitoring.
对健康体重承诺基金会(HWCF)市场承诺的一项独立评估发现,参与的公司达到并超过了其2012年的中期销售削减承诺。
这项于2013年进行的后续研究使用了2000年至2012年美国家庭有子女的购买数据,比较了在承诺前时期(2000 - 2007年)和承诺后时期(2008 - 2012年)HWCF、非HWCF名牌产品和自有品牌(PL)产品的卡路里购买趋势;控制了人口和经济因素同时变化的潜在影响,包括大衰退和食品价格;并评估了HWCF市场承诺是否与有子女家庭购买的消费品(CPG)卡路里减少有关。
2000年至2012年期间,所有品牌类别的有子女家庭的人均每日CPG卡路里购买量均有显著下降。根据承诺前的趋势,CPG卡路里购买量已经在下降。然而,在考虑经济、社会人口和长期因素后,从HWCF品牌购买的卡路里在承诺后的减少量低于预期,而从非HWCF名牌产品和自有品牌购买的卡路里减少量高于预期。
如果这16家HWCF公司能够维持其承诺前的轨迹,2012年有子女家庭从HWCF产品购买的卡路里应额外减少42千卡/人/天。2011年至2012年期间CPG总卡路里购买量没有变化,这让人对下降的可持续性产生质疑,并需要持续监测。
