Excess sugar consumption is a public health concern in the United States. How sugar purchases have changed over time, whether there are disparities across subpopulations, and the contribution of various food groups are unclear.
To assess trends in sugar from packaged foods and beverages purchased by US households between 2002 and 2020.
This is an open cohort study.
PARTICIPANTS/SETTING: We obtained data from the NielsenIQ U.S. Homescan Consumer Panel, which collects data on household purchases of all consumer packaged goods in 52 metropolitan and 24 non-metropolitan markets across the United States. We assessed data on food and beverage purchases for 1,163,447 household-years.
The primary outcomes are the total sugar in grams purchased per capita per day and percentage of calories from sugar, by sociodemographic group.
We used linear regression to estimate trends in total grams of sugar per capita per day, percentage of calories from sugar, and percentage of total sugar purchases by food or beverage group. We estimated means for select years and tested for significance compared with 2002 and with the previous timepoint and calculated the overall P-value for the linear trend using time series regression.
Total sugar purchases decreased over the study period, both in absolute terms (-37.2 g/capita/day; 95% confidence interval [CI], -38.7, -35.6) and as a percentage of total calories purchased (-5.3 percentage points; 95% CI, -5.5, -5.2). Sugar purchases declined for all sociodemographic groups, but disparities have persisted or widened, particularly among individuals who are non-Hispanic Black, low-income, and with lower educational attainment. Beverages' contributions to sugar purchases decreased 8.1 percentage points (95% CI, -8.4, -7.8).
In the United States, purchases of sugar declined, but disparities by socioeconomic status and race or ethnicity persisted or widened. Policies to further reduce sugar consumption and the burden of diet-related disparities are needed.
美国存在过度摄入糖的问题，这是公共卫生关注的重点。人们不清楚糖的购买量随时间发生了怎样的变化，不同亚人群之间是否存在差异，以及各种食物组的贡献如何。
评估美国家庭在 2002 年至 2020 年期间购买包装食品和饮料中的糖含量趋势。
这是一项开放队列研究。
参与者/设置：我们从尼尔森 IQ 美国家庭扫描消费者小组获得数据，该小组收集了全美 52 个大都市区和 24 个非大都市区家庭购买所有消费包装商品的数据。我们评估了 1,163,447 个家庭年的食品和饮料购买数据。
主要结局是按社会人口统计学分组计算的人均每日购买的总糖量（克）和来自糖的卡路里百分比。
我们使用线性回归估计人均每日购买的总糖量、来自糖的卡路里百分比和食物或饮料组购买的总糖量百分比的趋势。我们估计了特定年份的平均值，并与 2002 年和前一时间点进行了比较，并使用时间序列回归计算了线性趋势的总体 P 值。
在研究期间，总糖购买量下降，绝对值下降（-37.2 克/人/天；95%置信区间[CI]，-38.7，-35.6），作为总卡路里购买量的百分比下降（-5.3 个百分点；95% CI，-5.5，-5.2）。所有社会人口统计学群体的糖购买量都有所下降，但差异仍然存在或扩大，特别是在非西班牙裔黑人、低收入和教育程度较低的人群中。饮料对糖购买量的贡献下降了 8.1 个百分点（95% CI，-8.4，-7.8）。
在美国，糖的购买量有所下降，但社会经济地位和种族或民族的差异仍然存在或扩大。需要采取政策进一步减少糖的消耗和与饮食相关的差异负担。
