Although bariatric surgery has become more accessible in recent years, it is unclear whether populations disproportionately affected by obesity are utilizing this treatment. A cross-sectional analysis of the Nationwide Inpatient Sample was performed. The sociodemographic characteristics (race, sex, age, insurance, median income), co-morbidities, and weight loss surgery type were analyzed. Bariatric surgeries increased six-fold from 17,678 in 1998 to 112,882 in 2004 (p < 0.001). Thereafter, bariatric surgeries declined to 93,733 in 2007 (p = 0.24). The proportion of individuals of Other race undergoing bariatric surgery significantly increased, while the proportion of Whites significantly decreased over time. The proportion of individuals in the lowest income quartile (< $25,000) increased, while those in the highest income percentile (> $45,000) decreased. From 1998 to 2007, the sociodemographic characteristics of the bariatric surgery population have changed, although those that are disproportionately affected by morbid obesity continue to be underrepresented.
尽管近年来减重手术变得更加普及，但肥胖问题严重的人群是否利用了这种治疗方法尚不清楚。我们对全国住院患者样本进行了横断面分析。分析了社会人口统计学特征（种族、性别、年龄、保险、中位数收入）、合并症和减重手术类型。1998 年，减重手术为 17678 例，到 2004 年增至 112882 例（p<0.001）。此后，2007 年减重手术降至 93733 例（p=0.24）。接受减重手术的其他种族人群比例显著增加，而白人比例则随时间推移而显著下降。收入最低四分位数（<25000 美元）的人群比例增加，而收入最高百分位数（>45000 美元）的人群比例下降。从 1998 年到 2007 年，减重手术人群的社会人口统计学特征发生了变化，但受病态肥胖影响严重的人群仍未得到充分代表。
