ABSTRACT
Aim: This study aims to evaluate the association between dietary fatty acid intake and hypertension in children and adolescents. Methods: This cross-sectional study used data of children and adolescents aged 8-17 years from the National Health and Nutrition Examination Survey (NHANES) 2005-2018. Dietary intake of total fat and fatty acid was evaluated via two 24-h dietary recall interviews. Multivariate logistic regression models were used to assess the association between fatty acid intake and hypertension, with odds ratios (ORs) and 95% confidence intervals (CIs) calculated. A subgroup analysis was conducted according to gender, age, and body mass index Z-score. Results: This study included 13,330 subjects, of which 11,614 were non-hypertensive and 1,716 were hypertensive. Higher intake of total polyunsaturated fatty acids (PUFAs) was associated with significantly lower odds of hypertension (OR = 0.85, 95% CI: 0.74-0.97, P = 0.018). No significant associations were found between the density of total saturated fatty acid, monounsaturated fatty acids, and PUFAs and the odds of hypertension (all P > 0.05). Increased intake of omega-3 (OR = 0.82, 95% CI: 0.72-0.93, P = 0.002) and omega-6 (OR = 0.86, 95% CI: 0.75-0.98, P = 0.025) PUFAs, octadecatrienoic acid (OR = 0.82, 95% CI: 0.72-0.93, P = 0.003), and octadecadienoic acid (OR = 0.86, 95% CI: 0.75-0.98, P = 0.025) was associated with significantly lower odds of hypertension, and individuals with higher omega-6/omega-3 ratio had significantly higher odds of hypertension (OR = 1.09, 95% CI: 1.02-1.17, P = 0.025). The density of omega-3 PUFAs (OR = 0.86, 95% CI: 0.78-0.95, P = 0.004) and octadecatrienoic acid (OR = 0.87, 95% CI: 0.78-0.96, P = 0.006) was inversely associated with the odds of hypertension, and the omega-6/omega-3 ratio was positively associated with the odds of hypertension (OR = 1.09, 95% CI: 1.02-1.17, P = 0.012). Conclusion: Total PUFA intake was negatively associated with the odds of hypertension in children and adolescents. Higher intake of omega-3 and omega-6 PUFAs, octadecatrienoic acid, and octadecadienoic acid, as well as density of omega-3 PUFAs and octadecatrienoic acid, was associated with lower odds of hypertension.
ABSTRACT
OBJECTIVE: To investigate the significance of C-reactive protein (CRP) in the discrimination of acute appendicitis pathology and its guiding role in the timing of surgery. METHODS: 307 patients in our hospital from July 2012 to December 2013 were selected, who received appendectomy and simultaneous detections of WBC, neutrophil percentage and CRP; and Logistic regression analysis and Roc analysis of these indicators were conducted; Roc curve was drawn. RESULTS: Logistic regression analysis showed that the proportion of neutrophils and CRP were the risk factors to determine gangrenous appendicitis, but the box chart and Roc curves showed that C-reactive protein was superior to neutrophil classification in determining gangrenous appendicitis (areas under the curve were 0.882 and 0.667 respectively), and the best diagnostic cutoff value was 44.42 mg/L (sensitivity 73.1%, specificity 89.5%). CONCLUSION: C-reactive protein levels can help distinguish pathological types of acute appendicitis, which can be used as a reference index for surgery determination.
