ABSTRACT
Objective To investigate the relationship between exposure to famine in early life stage and hypertension phenotype and grade in middle and old age. Methods People born between 1951 and 1965 in the 2015 China Health and Elderly Care Follow-up Survey were included in the study, and were divided into unexposed group, fetal exposed group, childhood exposed group and adolescent exposed group according to the time of famine occurrence and birth year of the participants. Logistic regression model was used to explore the effects of different famine exposure periods in early life stage on hypertension classification （including normal high value, grade I, grade II and grade III） and phenotype （including isolated systolic hypertension[ISH], isolated diastolic hypertension [IDH] and combined systolic and diastolic hypertension [SDH]）. Results Compared with unexposed group, fetal famine exposure （OR=1.59, 95% CI :1.10-2.30）, childhood famine exposure （OR=1.67, 95% CI :1.04-2.70） and adolescent famine exposure （OR=3.42, 95% CI : 2.51-4.66） were the risk factors for ISH. Only famine exposure during adolescence （OR=1.54, 95% CI: 1.07-2.21） was a risk factor for SDH. In addition, fetal famine exposure （OR=1.41, 95% CI: 1.05-1.89） and adolescent famine exposure （OR=2.22 , 95% CI: 1.71-2.88） were risk factors for developing grade I hypertension. Famine exposure in childhood （OR=2.45, 95% CI: 1.21-4.94） and famine exposure in adolescence （OR=2.45, 95% CI: 1.44-4.19） were risk factors for grade 2 hypertension. Conclusion Famine exposure in early life stage was associated with the phenotype and grade of hypertension. Therefore, balanced nutrition in early life is important to prevent hypertension in adulthood.
ABSTRACT
BackgroundThe COVID-19 vaccines have been developed in a wide range of countries. This study aims to examine factors influencing vaccination rate and willingness to vaccinate against COVID-19 among Chinese healthcare workers (HCWs). MethodsFrom 3rd February to 18th February, 2021, an online cross-sectional survey was conducted among HCWs to investigate factors associated with the acceptance and willingness of COVID-19 vaccination. Socio-demographic characteristics and the acceptance of COVID-19 vaccination among Chinese HCWs were evaluated. ResultsA total of 2156 HCWs from 21 provinces in China responded to this survey (response rate: 98.99%)), among whom 1433 (66.5%) were vaccinated at least one dose. Higher vaccination rates were associated with older age (40-50 years vs. less than 30 years, OR=1.63, 95%CI: 1.02-2.58; >50 years vs. 30 years, OR=1.90, 95%CI: 1.02-3.52), working as a clinician (OR=1.54, 95% CI: 1.05-2.27), having no personal religion (OR=1.35, 95%CI: 1.06-1.71), working in a fever clinic (OR=4.50, 95%CI:1.54-13.17) or higher hospital level (Municipal vs. County, OR=2.01, 95%CI: 1.28-3.16; Provincial vs. County, OR=2.01, 95%CI: 1.25-3.22) and having knowledge training of vaccine (OR=1.67, 95%CI:1.27-2.22), family history for influenza vaccination (OR=1.89, 95%CI:1.49-2.35) and strong familiarity with the vaccine (OR=1.43, 95%CI:1.05-1.95) (All P<0.05). Strong willingness for vaccination was related to having a working in midwestern China (OR=1.89, 95%CI:1.24-2.89), considerable knowledge of the vaccine (familiar vs. not familiar, OR=1.67, 95%CI: 1.17-2.39; strongly familiar vs. not familiar, OR=2.47, 95%CI: 1.36-4.49), knowledge training of vaccine (OR=1.61, 95%CI: 1.05-2.48) and strong confidence in the vaccine (OR=3.84, 95%CI: 2.09-7.07). ConclusionPersonal characteristics, working environments, familiarity and confidence in the vaccine were related to vaccination rates and willingness to get vaccinated among healthcare workers. Results of this study could provide evidence for the government to improve vaccine coverage by addressing vaccine hesitancy in the COVID-19 pandemic and future public health emergencies.
ABSTRACT
Objective:To assess the efficacy of different non-drug smoking cessation interventions on smoking cessation among the high-risk populations of lung cancer screening by network meta-analysis.Methods:PubMed, MEDLINE (Ovid), PsychINFO, CNKI, WanFang and VIP databases were searched for randomized controlled clinical trials published from January 2010 to September 2020.According to the eligibility criteria, the retrieval literature was screened, the quality evaluation and data extraction were conducted, then, the statistical analysis was performed by using the Stata 14.0 software.Results:A total of 28 trials were included, including 34 640 cases of high-risk population, involving intervention measures, including 5R short quit smoking intervention, cognitive behavior therapy, award model quit smoking intervention, motivational interview, network intervention, telephone intervention, incentive mechanism plus telephone intervention, network plus telephone intervention, conventional treatment and blank group.The results of network meta-analysis showed that on the 7-day follow-up of 6 months, according to the score of SUCRA, the ranking of smoking cessation rate was 5R short smoking cessation intervention (0.88), cognitive behavior therapy (0.85), AWARD model smoking cessation intervention (0.80), incentive mechanism plus telephone intervention (0.73), motivational interview (0.53), Internet plus telephone intervention (0.40), Internet intervention (0.37), telephone intervention (0.31), conventional treatment (0.13) and blank group (0.03). However, on the 7-day smoking cessation rate of 12-month follow-up, the ranking of smoking cessation rate was 5R short smoking cessation intervention (0.94), AWARD model smoking cessation intervention (0.81), motivational interview (0.51), network intervention (0.40), telephone intervention (0.19) and conventional treatment (0.14).Conclusions:The existing evidence shows that no matter the length of follow-up, 5R short smoking cessation intervention has the best effect on smoking cessation in high-risk population of lung cancer screening.
