ABSTRACT
Objective@#To investigate the willingness to receive a COVID-19 vaccination and its influencing factors among individuals that missed the second dose of the inactivated COVID-19 vaccine in Zhejiang Province, so as to provide the evidence for improving the strategy for COVID-19 vaccination.@*Methods@#Individuals that did not receive the second dose of the inactivated COVID-19 vaccine after 56 days of getting the first dose (missed individuals) from March and May, 2021, were randomly sampled from Zhejiang Provincial SaaS Vaccination Information System. Their basic information, status of getting the inactivated COVID-19 vaccine and willingness to receive the second dose of the inactivated COVID-19 vaccine were collected through telephone interviews. The factors affecting the willingness to receive the second dose of the inactivated COVID-19 vaccine were identified among the missed individuals using a multivariable logistic regression model. @* Results@# Totally 562 individuals were investigated, and there were 292 (51.96%) valid respondents. There were 54 actual missed individuals, with a mean age of (40.91±16.75) years, which included 39 men (72.22%) and 15 women (27.78%). Of all missed individuals, 23 had an educational level of junior high school and below (42.59%). The mean duration from the time of investigation to the time of getting the first dose of the inactivated COVID-19 vaccine was (137±28) days. A half of the missed individuals were willing to receive the second dose of the inactivated COVID-19 vaccine. Multivariable logistic regression analysis showed high willingness to receive the second dose of the inactivated COVID-19 vaccine among the missed individuals with requirements of vaccination in the workplace (OR=5.393, 95%CI: 1.112-26.152) and low willingness among the missed individuals that felt physical discomfort after receiving the first dose (OR=0.168, 95%CI: 0.035-0.806). @*Conclusions@#The willingness to receive the second dose of the inactivated COVID-19 vaccine was low among the missed individuals, and high willingness is seen among the missed individuals with requirements of vaccination in the workplace and without physical discomfort after receiving the first dose of the inactivated COVID-19 vaccine.
ABSTRACT
Objective To explore the influential factors of esthetic evaluation of mandibular prominence by orthodontic patients from two dimensions (ideal value and tolerance range).Methods 226 orthodontic patients were investigated by an electronic questionnaire of esthetic evaluation of mandibular prominence.Binary logistic regression was adopted to analyze the influential factors.Results The tolerable boundary value for female mandibular retrognathism was affected by age (OR1.360) and orthodontic history (OR2.849).The tolerable boundary value for female mandibular prognathism and male mandibular retrognathism were found to be affected by orthodontic history (OR2.557 and 2.845,respectively).The tolerable boundary value for male mandibular prognathism was affected by age (OR1.347) and orthodontic history (OR2.310).The ideal value of male mandibular prominence was affected by age (OR1.420).Conclusions Orthodontic patients' esthetic evaluation of mandibular prominence is influenced by age and treatment condition,but not by sex,education level,marital status and personal profile.
ABSTRACT
Objective To investigate the level and its influencing factors of quality of life for burn patients undergoing amputation,and take treatment measures for clinical nursing. Methods The single factor analysis method was taken on the burn patients undergoing amputation in different social demographic characteristics from January 2013 to July 2016. Results The score of quality of life was (56.08 ± 17.97) points,and the four dimensions scored as physical function (63.64 ± 27.51) points, mental health(54.76±20.28)points,social relations(58.71±19.19)points and general health(46.00±18.61)points, which were at a low level.Multiple regression analysis showed that the influencing factors of quality of life were patient education, marital status, cost source, economic conditions, prosthetic replacement, and amputation site,which had a statistically significant difference between the effects on the quality of life(F/t=4.367,3.836,4.436,4.412,2.916,4.591,P<0.01)and into stepwise multiple regression equations.The patient′s age and career had statistically significant(F=3.495,3.640,P<0.05),but not into stepwise multiple regression euqtions. Conclusions Burn patients undergoing amputation are physical and spiritual double whammy,through to the influencing factors,clinical medical staff to be able to make this part of the population cause enough attention,enhancing the quality of life,strive for an early return to family and society.
ABSTRACT
Objective To explore the related factors that might had effect on orthodontic patients' esthetic evaluation of axial dental midline angulation from three aspects which are ideal value,detectable value and tolerable value.Methods Photographs of a smiling woman was digitally manipulated to produce models with left or right maxillary axial dental midline angulations in 2° increments.These digital photographs models were used to develop an electronic questionnaire in combination with corresponding guidance for each question.The electronic questionnaire was applied to investigate the esthetic evaluation of axial dental midline angulation from 222 orthodontic patients who complied with the inclusion criteria.Esthetic evaluation included three aspects,the ideal value,the detectable value and the tolerable value,which represented the degrees of maxillary axial dental midline angulations the patients considered to be ideal,detectable and tolerable,respectively.The patients' personal information and clinical orthodontic examination results were collected as well.Results The mean detectable value and tolerable value were 4.9° and 9.7°,the median of detectable value and tolerable value were 5°and 9.5°.Logistic regression analysis was applied to explore the influence of seven factors on each evaluator's ideal value,detectable value and tolerable value.The seven factors were gender,marriage condition,education level,orthodontic treatment condition,malocclusion index,dental esthetic rating from others and from themselves.The statistical analysis indicated education level and orthodontic treatment condition were the influential factors of detectable values,while the tolerable values were influenced by the education level and gender.The ideal value converged to 0° and none of the factors had effect on it.Conclusions The education level,orthodontic treatment condition and gender are considered to be the influential factors of the esthetic evaluation of axial dental midline angulation.
ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the most acceptable lower anterior face height of male and female by orthodontic treatment seeking people.</p><p><b>METHODS</b>Two hundred and thirty-two Chinese orthodontic seeking people of Guanghua Hospital of Stomatology of Sun Yat-sen University were randomly selected in this survey. An electronic questionnaire was designed with a set of male and female young Chinese adult images with changes of the lower anterior face height (while the middle anterior face height remains the same). They were asked about the lowest, highest and optimal proportion (or so-called lower, higher and optimum limits respectively) between the lower anterior face height and the middle anterior face height (LAFH/MAFH) they could accept. All the findings of the proportion were analyzed by a statistic system.</p><p><b>RESULTS</b>The lower limits' median value in regard to the LAFH/MAFH of male model and female model images was 0.8, this limit value for the male model's was greater than the female model's (P = 0.039); the higher limits' median value was 1.1, this limit value for the male model's was less than the female model's (P < 0.001); the optimum limits' median value was 0.9, this limit value for the male model's was greater than the female model's (P < 0.001).</p><p><b>CONCLUSION</b>The result of this study shows all lower, higher and optimal limits accepted by the orthodontic treatment seeking people in regard to the proportion between the lower and middle height of anterior faces. This result will facilitate the understanding of aesthetic judgments of orthodontic patients on profile lower anterior facial height for orthodontist in treatments.</p>
