This study examined the prevalence of obesity and severe obesity among Mississippi K-12 public school students and the obesity rate differences within subgroups categorized by sex, race, and grade level. Anthropometric data from a weighted, representative sample of Mississippi public school students were collected through the biennial Child and Youth Prevalence of Obesity Survey (CAYPOS). Overall prevalence rates and those of the subgroups were calculated and compared. The 2017 data indicated that overall 23.7% of Mississippi public schools students met the criterion of class I obesity, 9.1% met the criterion of class II obesity, and 3.2% met the criterion of class III obesity. Among those with severe obesity, the prevalence was significantly higher among black students (10.9%) when compared to their white counterparts (7.3%) ( < 0.001), and among high school students (12.0%) when compared to elementary (6.5%) and middle school students (9.6%) ( < 0.001). As to racial differences by sex, black females had the highest severe obesity rates (11.9%), followed by black males (9.9%). White females had the lowest severe obesity rate (5.8%). At lower grade levels, black students had higher prevalence rates than whites but at 12 grade level the gap between the two races are almost closed. These findings were compared to other current studies in order to better evaluate the current health profiles of Mississippi public school students.
本研究调查了密西西比州幼儿园至12年级公立学校学生中肥胖和重度肥胖的患病率，以及按性别、种族和年级划分的亚组内肥胖率差异。通过两年一次的儿童和青少年肥胖患病率调查（CAYPOS），收集了来自密西西比州公立学校学生加权代表性样本的人体测量数据。计算并比较了总体患病率和亚组患病率。2017年的数据表明，总体而言，23.7%的密西西比州公立学校学生符合I类肥胖标准，9.1%符合II类肥胖标准，3.2%符合III类肥胖标准。在重度肥胖者中，黑人学生的患病率（10.9%）显著高于白人学生（7.3%）（<0.001），高中生的患病率（12.0%）高于小学生（6.5%）和初中生（9.6%）（<0.001）。按性别划分种族差异，黑人女性的重度肥胖率最高（11.9%），其次是黑人男性（9.9%）。白人女性的重度肥胖率最低（5.8%）。在较低年级，黑人学生的患病率高于白人，但在12年级时，两个种族之间的差距几乎消失。将这些发现与其他当前研究进行比较，以便更好地评估密西西比州公立学校学生目前的健康状况。
