背景资料：研究表明，快餐店和便利店数量多，超市和杂货店数量少的建筑环境与肥胖，II型糖尿病和其他慢性疾病有关。由于很少有研究在县一级评估这些关系，我们的目的是检查快餐店密度，便利店密度，超级商店密度，杂货店密度和南卡罗来纳州各县的II型糖尿病患病率。方法：四种类型的食品出口密度-快餐店，便利店，超级商店，和杂货店-和II型糖尿病的患病率进行了计算。这些食品出口密度之间的关系与II型糖尿病的患病率进行了映射，并完成了OLS回归分析，调整了县级肥胖率，身体活动，娱乐设施密度，失业率，无车家庭和有限的商店访问，教育和种族。我们发现快餐店密度与II型糖尿病患病率之间存在显著的负相关，便利店密度与II型糖尿病患病率之间存在显著的正相关。在调整后的分析中，食品出口密度（任何类型）与II型diabetes.Conclusions的患病率无关：这种生态分析表明，快餐店，便利店，超级商店，或杂货店的密度和II型糖尿病的患病率之间没有关联。在未来的研究中，需要考虑环境，社会和文化的决定因素，以及个人行为。
Background: Studies suggest that the built environment with high numbers of fast food restaurants and convenience stores and low numbers of super stores and grocery stores are related to obesity, type II diabetes mellitus, and other chronic diseases. Since few studies assess these relationships at the county level, we aim to examine fast food restaurant density, convenience store density, super store density, and grocery store density and prevalence of type II diabetes among counties in South Carolina.Methods: Pearson's correlation between four types of food outlet densities-fast food restaurants, convenience stores, super stores, and grocery stores-and prevalence of type II diabetes were computed. The relationship between each of these food outlet densities were mapped with prevalence of type II diabetes, and OLS regression analysis was completed adjusting for county-level rates of obesity, physical inactivity, density of recreation facilities, unemployment, households with no car and limited access to stores, education, and race.Results: We showed a significant, negative relationship between fast food restaurant density and prevalence of type II diabetes, and a significant, positive relationship between convenience store density and prevalence of type II diabetes. In adjusted analysis, the food outlet densities (of any type) was not associated with prevalence of type II diabetes.Conclusions: This ecological analysis showed no associations between fast food restaurants, convenience stores, super stores, or grocery stores densities and the prevalence of type II diabetes. Consideration of environmental, social, and cultural determinants, as well as individual behaviors is needed in future research.
