Abstract

Background: We tested the operational feasibility of body mass index (BMI) field charts in nutritional assessment of adult patients with tuberculosis (PwTB), which obviate calculations and provide nutritional status based on BMI and the ideal weight (BMI = 21 kg/m²).

Methods: We trained primary health care providers (HCPs) in 39 primary health centres for nutritional assessment and classification and identifying the ideal weight using BMI field charts in PwTB. Using the descriptive statistics method, we analysed the collected data and reported the nutritional status in PwTB and the uptake of the field charts among the HCPs.

Results: The median (interquartile range [IQR]) weight and BMI were 44 kg (37.0, 50.0) and 16.9 kg/m² (15.2, 18.9), respectively, in 214 PwTB, of which 146 (68.2%) patients had a BMI of <18.5 kg/m². The HCPs documented the ideal weight in 155 (72.4%) patients, which was correct in 147 (94.8%) patients. The median (IQR) weight deficit to achieve the ideal weight was 10.4 kg (7.3, 12.8) in men and 11.9 kg (7.0, 17.9) in women. For a BMI of 18.5 kg/m², the deficit was 6.4 kg (3.4, 8.5) in men and 11.3 kg (4.6, 13.6) in women.

Conclusion: The magnitude and severity of undernutrition in adult PwTB in a well-performing district of Karnataka in South India were high. A single training session successfully improved nutritional assessment and BMI field chart usage among the primary HCPs.

在卡纳塔克邦对成年结核病患者进行营养评估的BMI现场图表的实施。

背景：我们测试了体重指数（BMI）现场图在成年结核病（PwTB）患者营养评估中的操作可行性，该图表避免了计算，提供了基于BMI和理想体重（BMI = 21 kg/m2）的营养状况。方法：我们对39个初级卫生保健中心的初级卫生保健提供者（HCPs）进行营养评估和分类，并使用体重指数现场图确定PwTB的理想体重。采用描述性统计方法，对收集到的数据进行分析，并报告了病株的营养状况和田间图在HCPs中的吸收情况。结果：214例PwTB患者体重和BMI的中位数（四分位间距[IQR]）分别为44 kg（37.0, 50.0）和16.9 kg/m2(15.2, 18.9)，其中146例（68.2%）患者BMI为2。HCPs记录了155例（72.4%）患者的理想体重，147例（94.8%）患者的正确体重。达到理想体重的中位体重差（IQR）男性为10.4 kg(7.3, 12.8)，女性为11.9 kg（7.0, 17.9）。对于体重指数为18.5 kg/m2的人群，男性为6.4 kg(3.4, 8.5)，女性为11.3 kg（4.6, 13.6）。结论：在印度南部卡纳塔克邦的一个表现良好的地区，成年PwTB的营养不良程度和严重程度很高。单次培训成功地改善了初级保健医师的营养评估和BMI现场图表的使用。
