Abstract: Objective To understand the basic situation of the nutritional risk occurrence in hospitalized patients with bone tuberculosis, and the differences in the occurrence of nutrition risk rate among different sex and age. Methods We collected the basic information of all patients with bone tuberculosis in our hospital from January 2014 to March 2014. A total of 64 patients (male 31,female 33) were collected. The age ranges from 19 to 87 years old, 20 cases fell in 19- age group, 27 cases in 41- age group, 17 cases in 61-87 age group. We made nutritional risk screening and measurement based on NRS2002 (the highest score is 7, ≥3 is considered having nutritional risk).We used the Spearman’s rank correlation to measure nutritional risk and analyze the correlation among those indexes. The Chi-square test is used for comparison and P<0.05 is considered statistically significance.  Results Nutritional risk score has a positive correlation with age (the age range was （43.3±16.9） to （81.7±5.0）years old when the score was between 1 to 5), CRP (the range of CRP was between （16.0±16.2） to （21.1±18.2）mg/L when the score was between 1 to 5), days of hospitalization (the days of hospitalization was between （17.7±7.4） to （21.3±12.1）d when the score was between 1 to 5) (r=0.304,0.352,0.370; P<0.05 or P<0.01); Nutritional risk score has a negative correlation with body weight (the body weight was between （66.3±11.9） to （49.0±9.6）kg when the score was between 1 to 5), BMI (the BMI value was between （23.5±3.8） to （18.6±1.5）kg/m² when the score was between 1 to 5), Hb (the Hb value was between （134.3±18.5） to （106.3±24.8）g/L when the score was between 1 to 5), L% (the L% value was between （26.5±7.3)% to （17.3±4.0）% when the score was between 1 to 5), Alb (the Alb value was between （41.5±3.3） to （31.4±4.7）g/L when the score was between 1 to 5), Na⁺ (the Na⁺ value was between （138.7±2.6） to （139.7±1.1）mmol/L when the score was between 1 to 5), K⁺ (the K⁺ value was between （4.5±0.4） to （4.1±0.5）mmol/L when the score was between 1 to 5) (r=-0.419,-0.469,-0.418,-0.279,-0.556,-0.255,-0.433; P<0.05 or P<0.01). In our statistical analysis, the occurrence of nutritional risk of patients with bone tuberculosis was 37.5% (24/64), compared with female patients (45.5%,15/33), male patients is lower (29.0%,9/31), but there was no statistically difference between the two groups (χ²=1.839，P>0.05). The occurrence of nutritional risk of patients in 19- age group was 25.0%(5/20), which was 29.6% (8/27) in 41- age group, and the rate was 64.7%(11/17) in 61-87 age group, there was statistically difference among different age groups（χ²=7.416，P<0.05）.  Conclusion Nutritional risk occurrence among our hospitalized patients with bone tuberculosis is high, and we should early screen for nutritional risks and carry on active intervention.
