RESUMEN
Objective The prevalence of nonalcoholic fatty liver disease(NAFLD) is increasing in middle-aged and older people. This article aimed to analyze the relationship between thyroid hormone and NAFLD in euthyroid middle-aged and older people.Methods We retrospectively analyzed 589 euthyroid patients aged 40 years or older who were hospitalized in our department from January 2015 to December 2017. According to the Results of abdominal ultrasound, they were divided into NAFLD group (n=217) and non-NAFLD group (n=372). We compared the differences of general data between two groups and analyzed the association of thyroid hormones(FT3, TSH) with metabolic indexes and the risk of NAFLD.Results TSH and FT3 in NAFLD group were significantly higher than those in non-NAFLD group (respectively 2.18±1.01 mIU/L versus 1.74±0.77 mIU/L, P<0.001; 4.54±0.72 pmol/L vs 4.05±0.83 pmol/L, P<0.001). After adjusting for age and sex, TSH was positively correlated with BMI, abdominal circumference, and LDL (r, P respectively were 0.117, 0.005; 0.136, 0.001; 0.086, 0.037). FT3 was positively correlated with LDL (r=0.098, P=0.017), and negatively correlated with FPG and HbA1c (r, P respectively were -0.161, <0.001; -0.139, 0.001). With the increase of TSH and FT3 quartiles, the risk of NAFLD showed a significantly increasing trend (P<0.01). Logistic regression analysis showed that abdominal circumference, BMI, ALT, TG, TSH, and FT3 were independent risk factors of NAFLD. Conclusion TSH and FT3 are risk factors of NAFLD in euthyroid middle-aged and older people, which can be used as a good serological indicator of NAFLD.
RESUMEN
Objective To investigate the awareness of osteoporosis and its influential factors in middle-aged and older people. Methods By using self-designed questionnaire, 354 middle-aged and old people were investigated as to their awarness of osteoporosis in Chajiao street community in Guangzhou. Among them, 58 people were measured the bone density in the calcaneal bone by Ultrasound. Results The average score of the questionnaire was 9.46 ± 5.13, and the accuracy was 39.4%. In the diagnosis and treatment, the accuracy was just 17.8%. The diet (the accuracy in 54%) and sport (the accuracy in 50.3%) were good. The statistical analyses showed the linear relationship between the T value of bone density and the age (P = 0.021), between the T value and the score (P = 0.047). Wilcoxon rank sum test found that the T value between female and male was significantly different (Z = -3.749, P < 0.000). With multiple linear regression analysis, the T value had a linear correlation with the score (F = 4.224, P = 0.045) positively. Conclusions Currently, the awareness of osteoporosis in the middle-aged and old people was inadequate. To better prevent osteoporosis, the propogation of knowledge and guidance provided by clinicians in osteoporosis should be improved necessarily and emergently.
