目标。我们调查了对含糖饮料（SSBs）征税是否会改善巴西家庭的饮食。我们使用了巴西地理和统计研究所在2002-2003年间从48470个巴西家庭的全国代表性样本中收集的家庭食品消费数据。SSB的消耗量表示为消耗的总SSB卡路里和购买的总卡路里中SSB的百分比。我们用回归模型调查了价格弹性，控制了人口变量、收入和所有其他食品和饮料的价格。SSBs价格的上涨导致了消费的减少。SSB价格每上涨1.00%，其热量消耗就会减少0.85%（穷人减少1.03%，非穷人减少0.63%）。收入增加对SSB消费有积极影响，但影响不到价格弹性大小的一半（收入每增加1.00%，SSB卡路里消费增加0.41%）。巴西SSB的高价格弹性表明，对购买重量或体积征税将导致SSB消费减少。[J] .中华卫生杂志，2012;32(2):368 - 368。doi: 10.2105 / AJPH.2011.300313)
Objectives. We investigated whether taxing sugar-sweetened beverages (SSBs) would improve the diets of households in Brazil.Methods. We used household food consumption data that the Brazilian Institute of Geography and Statistics collected in 2002-2003 from a nationally representative sample of 48470 Brazilian households. The consumption of SSBs is expressed as the total SSB calories consumed and as the SSB percentage of the total calories purchased. We investigated price elasticity with regression models, controlling for demographic variables, income, and prices of all other foods and drinks.Results. Increases in the price of SSBs led to reductions in consumption. A 1.00% increase in the price of SSBs led to a 0.85% reduction of SSB calories consumed (1.03% reduction for the poor and 0.63% for the nonpoor). Increased income had a positive effect on SSB consumption, but the effect was less than half the size of the price elasticity (0.41% increase in SSB calories consumed for every 1.00% increase in income).Conclusions. High SSB price elasticity in Brazil indicates that a tax on purchased weight or volume would lead to reductions in SSB consumption. (Am J Public Health. 2012;102:178-183. doi:10.2105/AJPH.2011.300313)
