Objective:To investigate the factors influencing the prescribing habits of general practitioners (GPs) in relation to single-pill combination (SPC) antihypertensive drugs.Methods:This was a qualitative study. Using the purposive sampling method, 2 general hospitals (designated as HAZ1-2) and 4 community health service centers (designated as HAS1-4) in Huai′an city, Jiangsu province were selected from April to May 2023. In addition, 4 general practitioners (designated as A-D) were selected as interviewees from each general hospital and center. The selected individuals were interviewed using on-site thematic group interviews. The interview mainly included the principles of clinical selection of SPC antihypertensive drugs; the degree of acceptance of SPC antihypertensive drugs by patients after prescription; the evaluation of SPC antihypertensive drugs and the difficulties existing in their clinical use. The data of the interview were analyzed according to the thematic framework.Results:Twenty-four GPs were interviewed. Four themes and 9 sub-themes were extracted regarding factors influencing GP prescribing of SPC antihypertensive drugs. The study showed that: (1) the prescribing of SPC antihypertensive drugs by GPs according to patients′ specific conditions; (2) the prescribing of SPC antihypertensive drugs by GPs was influenced by factors such as price and drug adjustment; (3) the different evaluations of SPC antihypertensive drugs among GPs; (4) GPs in community health service centers faced many difficulties in prescribing SPC antihypertensive drugs (relatively fewer varieties of SPC drugs in the community, lower patient trust in community GPs, and lower standardization of prescribing by community GPs).Conclusion:The factors influencing GPs′ prescribing of SPC antihypertensive drugs mainly include the patients′ specific situation, price, medication adjustment, attitude of GPs, and some clinical practice problems.

Objective:To investigate the correlation between relative fat mass(RFM)and Estimated Glomerular Filtration Rate(eGFR)in an elderly hypertensive population.Methods:This cross-sectional study enrolled elderly hypertensive individuals aged 65 years and older from Huai'an city between June 2023 and December 2023.Clinical data for these subjects were collected, and RFM and eGFR were calculated according to established formulas.Subsequently, the subjects were divided into two groups based on their eGFR levels: the eGFR normal group and the eGFR decreased group.Differences between these two groups were compared.Multivariate logistic regression models were employed to analyze the association between RFM and eGFR, and a subgroup analysis was conducted.The predictive value of RFM for renal function decline was evaluated using receiver operating characteristic curves(ROC).Results:Among the 2, 603 subjects, 921(35.4%)were assigned to the eGFR decreased group, while 1, 682(64.6%)were assigned to the eGFR normal group.The proportion of males, married individuals, smokers, and alcohol drinkers, as well as diastolic blood pressureand cultural levels, were significantly lower in the eGFR decreased group compared to the eGFR normal group (all P<0.05). Conversely, the duration of hypertension, proportion of comorbidities, age, fasting blood glucose, triglycerides, low-density lipoprotein cholesterol(LDL-C), relative fat mass(RFM), visceral fat index(VAI), dysfunctional obesity index(DAI), body roundness index(BRI), and conicity index(C-index)were all significantly higher in the eGFR decreased group compared to the eGFR normal group(all P<0.05). After adjusting for confounding factors, multivariate logistic regression analysis revealed that when RFM was treated as a continuous variable, the risk of eGFR decline increased with rising RFM(odds ratio[ OR]=1.035, 95% confidence interval[95% CI]: 1.008-1.063, P=0.010). When grouped according to RFM quartile levels(in ascending order)into Q1(<26.22), Q2(26.22-<30.53), Q3(30.53-<39.26), and Q4(≥39.26), using the Q1 group as a reference, the risk of eGFR decline increased in the Q3( OR=1.691, 95% CI: 1.777-2.430, P=0.004)and Q4( OR=1.743, 95% CI: 1.118-2.717, P=0.014)groups.In the subgroup analysis, gender( P-interaction=0.034)and smoking( P-interaction=0.012)were identified as having significant interaction effects on RFM and the decline in eGFR.In the male subgroup( OR=1.067, 95% CI: 1.027-1.108, Ptrend=0.001)and the smoking subgroup( OR=1.109, 95% CI: 1.026-1.199, Ptrend=0.009), the risk of eGFR decline significantly increased with higher levels of RFM.The restricted cubic spline(RCS)analysis indicated that when RFM exceeded 30.609, the risk of eGFR decline increased with rising RFM levels, demonstrating a non-linear correlation between RFM and the risk of eGFR decline( Pnonlinearity=0.048 5). The ROC curve analysis revealed that the area under the curve(AUC)for RFM in predicting eGFR reduction was 0.635(95% CI: 0.613-0.657, P1<0.001), which was significantly higher than the AUC for VAI(AUC=0.573, 95% CI: 0.550-0.596, P2<0.001), DAI(AUC=0.562, 95% CI: 0.539-0.584, P2<0.001), BRI(AUC=0.564, 95% CI: 0.541-0.587, P2<0.001), and the C-index(AUC=0.536, 95% CI: 0.513-0.559, P2<0.001). Conclusions:Elevated RFM is an independent risk factor for eGFR decline in elderly hypertensive individuals.There exists a significant interaction between gender and smoking with respect to the risk of RFM and eGFR decline.Additionally, RFM demonstrates a notable predictive value for eGFR decline in elderly hypertensive individuals.
