METHODS: The aims of the current retrospective study were threefold: first, to confirm the relationships of BMI, BMI-SDS and age in adolescent inpatients in a larger sample; second, to systematically assess the relationship of BMI, BMI-SDS, body height-SDS and age in adult inpatients at the time of referral; and third, to assess body height-SDSs and age to evaluate stunting.
RESULTS: We included 1001 girls (aged 12-17.9 years) and 1371 women (aged 18-73 years) admitted to inpatient treatment between 2014 and 2021. Mean BMI at admission was 14.95 kg/m2 (SD = 1.43; range 10.67-18.47) in adolescents and 14.63 kg/m2 (SD = 2.02; range 8.28-18.47) in adults. None of the adolescent patients but 20 adults had very low BMI values below 10 kg/m2. Adolescents showed a small but significant positive correlation between age and BMI (r = 0.12; p = 2.4 × 10-4). In adults, BMI was not correlated with age (r = -0.03; p = 0.3). BMI-SDSs was negatively correlated with age in adolescents and less so in adults (r = -0.35; p < 0.001 and r = -0.09; p = 0.001). Curve fit analyses for all patients indicated that there was a quadratic (age × age) relationship between age and BMI-SDS. Height correlated positively with BMI in adult (r = 0.1; p < 0.001) and adolescent (r = 0.09 p = 0.005) patients and we detected no evidence for stunting.
CONCLUSIONS: In conclusion, the BMI of inpatients seems to be relatively stable across the age span with mean values between 14 and 15 kg/m2. BMI values initially increase with age in younger patients, drop between ages 18 and 23 and then slowly decline with age.
方法:当前回顾性研究的目的有三个方面:第一,为了确认BMI之间的关系,在更大的样本中,青少年住院患者的BMI-SDS和年龄;第二,为了系统地评估BMI之间的关系,BMI-SDS,转诊时成人住院患者的身高-SDS和年龄;第三,评估身高-SDS和年龄以评估发育迟缓。
结果:我们包括2014年至2021年期间接受住院治疗的1001名女孩(12-17.9岁)和1371名妇女(18-73岁)。青少年入院时的平均BMI为14.95kg/m2(SD=1.43;范围10.67-18.47),成年人为14.63kg/m2(SD=2.02;范围8.28-18.47)。青少年患者中没有一个,但20名成年人的BMI值非常低,低于10kg/m2。青少年在年龄和BMI之间显示出较小但显着的正相关(r=0.12;p=2.4×10-4)。在成年人中,BMI与年龄无关(r=-0.03;p=0.3)。在青少年中,BMI-SDS与年龄呈负相关,而在成年人中,BMI-SDS与年龄呈负相关(r=-0.35;p<0.001,r=-0.09;p=0.001)。所有患者的曲线拟合分析表明,年龄与BMI-SDS之间存在二次(年龄×年龄)关系。成人(r=0.1;p<0.001)和青少年(r=0.09p=0.005)患者的身高与BMI呈正相关,我们没有发现发育迟缓的证据。
结论:结论:住院患者的BMI在整个年龄段似乎相对稳定,平均值在14~15kg/m2之间.在年轻患者中,BMI值最初随着年龄的增长而增加,在18至23岁之间下降,然后随着年龄的增长而缓慢下降。
