Obesity can be considered a global public health problem that affects virtually all countries worldwide and results in greater use of healthcare services and higher healthcare costs. We aimed to describe average monthly household medicine expenses according to source of funding, public or private, and to estimate the influence of the presence of obese residents in households on total medicine expenses.
This study was based on data from the 2008-2009 Brazilian Household Budget Survey, with a representative population sample of 55,970 households as study units. Information on nutritional status and medicines acquired and their cost in the past 30 days were analyzed. A two-part model was employed to assess the influence of obesity on medicine expenses, with monthly household medicine expenses per capita as outcome, presence of obese in the household as explanatory variable, and adjustment for confounding variables.
Out-of-pocket expenses on medicines were always higher than the cost of medicines obtained through the public sector, and 32 % of households had at least one obese as resident. Monthly household expenses on medicines per capita in households with obese was US$ 20.40, 16 % higher than in households with no obese. An adjusted model confirmed that the presence of obese in the households increased medicine expenses.
Obesity is associated with additional medicine expenses, increasing the negative impact on household budgets and public expenditure.
肥胖可被视为一个全球公共卫生问题，几乎影响到世界上所有国家，并导致医疗服务使用增加和医疗成本上升。我们旨在按资金来源（公共或私人）描述家庭每月平均药品费用，并估计家庭中肥胖居民的存在对药品总费用的影响。
本研究基于2008 - 2009年巴西家庭预算调查的数据，以55970户具有代表性的人口样本作为研究单位。分析了过去30天内的营养状况、购买的药品及其费用信息。采用两部分模型评估肥胖对药品费用的影响，以人均家庭每月药品费用为结果，家庭中肥胖者的存在为解释变量，并对混杂变量进行调整。
药品自付费用始终高于通过公共部门获得药品的费用，32%的家庭至少有一名肥胖居民。有肥胖居民的家庭人均每月药品费用为20.40美元，比没有肥胖居民的家庭高出16%。一个调整后的模型证实，家庭中肥胖者的存在会增加药品费用。
肥胖与额外的药品费用相关，增加了对家庭预算和公共支出的负面影响。
