Suboptimal medication adherence in young women living with HIV infection: a Korean nationwide claims study

The epidemiological characteristics of women living with human immunodeficiency virus (HIV) infection have gained little attention as the numbers are small compared with men living with HIV in the Republic of Korea. However, these data are important to achieve effective HIV infection control and to consider the influence of socioeconomic status on HIV transmission. This study utilized the claims database of the Korean National Health Insurance system to analyze women with a newly diagnosed HIV infection during the period 2009-2016. Adherence to antiretroviral agents was calculated using the medication possession ratio. Among 677 women with a newly diagnosed HIV infection, 219 (32.4%) were over 50 years of age; 291 (43.0%) were identified as having acquired immune deficiency syndrome (AIDS). A total of 99 women (14.6%) were National Medical Aid beneficiaries. Optimal medical adherence >95% was found in 62.2% of subjects. Teenage years (odds ratio(OR) 14.9, 95% confidence interval (95CI) 4.9-44.8), AIDS (OR 1.7, 95CI 1.2-2.3), and low economic status requiring National Medical Aid (OR 3.0, 95CI 2.0-4.6) were associated to adherence. Diagnosis prior to 2012 was also associated with poor adherence. In women, particularly young patients with low economic status, extra attention is required to enhance adherence to prescribed medication.

Factors Influencing HPV Vaccination Intention in Mothers with Elementary School Daughters

PURPOSE

The purpose of this study was to identify the impacts of human papillomavirus (HPV) vaccination-related health belief, attitudes toward HPV vaccination, and subjective norms on HPV vaccination intent targeting mothers of elementary school daughters.

METHODS

The study use a correlative survey design. The subjects of the study were 121 mothers of elementary school daughters located in metropolitan city B. All subjects agreed to participate in the study. The data were collected from September 1 to October 18, 2018, and were analyzed using descriptive statistics, Independent t-test, ANOVA with a post hoc Scheffé test, Pearson's correlation coefficients, and stepwise multiple regression.

RESULTS

Attitude toward HPV vaccination, subjective norms, vaccination plans for their children, and mother's vaccination status were significant factors influencing HPV vaccination intention. These factors accounted for 72% of the HPV vaccination intention. CONCLUSIONS: This study showed that factors affecting the intention of mothers of elementary school daughters to vaccinate against HPV were HPV vaccination attitudes, subjective norms, vaccination plans for their children, and mother's vaccination status. The biggest influencing factor was HPV vaccination attitudes. Therefore, in order to encourage mothers of elementary school daughters to vaccinate against HPVs, national-level policies should be implemented to create a social atmosphere of positive attitudes toward HPV vaccinations that also emphasizes how easy it is to get vaccinated against HPV. Based on this, mothers of elementary school daughters should be encouraged to have them vaccinated against HPV, thus contributing to improving the HPV vaccination rates of elementary school girls.

Mothers' intentions to vaccinate their teenaged children against human papillomavirus, as predicted by sex in South Korea: An application of the theory of planned behavior

AIM

This study was conducted in order to examine the intention of mothers to vaccinate their teenaged children against human papillomavirus (HPV) infection, according to the children's sex. Based on the theory of planned behavior, the study identified the sex-specific predictors of mothers' intention to vaccinate their teenaged children against HPV.

METHODS

This was a descriptive survey study that included, as participants, 200 mothers whose teenaged children were not vaccinated against HPV.

RESULTS

The mothers' experience with HPV vaccination was a significant predictor of their childrens' HPV vaccination status. For the mothers of sons, subjective norms, attitudes, and perceived behavioral control were found to be significant predictors of intention of HPV vaccination, with an explanatory power of 69.5%. For those with daughters, only attitudes and subjective norms were significant predictors, with an explanatory power of 79.6%.

CONCLUSION

The application of the theory of planned behavior is an effective method to determine the predictors of children's HPV vaccination status. In order to improve the HPV vaccination rate of teenaged children, strategies for education and effective promotion that involve mothers should be developed.

Factors associated with the intention to recommend human papillomavirus vaccination among Korean school health teachers

PURPOSE

The purposes were to examine Korean school health teachers' knowledge and attitudes toward human papillomavirus (HPV) and HPV vaccination, identify factors associated with their intention to recommend the HPV vaccine, and characterize school health teachers' communication with students or parents regarding the HPV vaccine.

DESIGN AND METHODS

The online survey involved 119 school health teachers in Korea.

RESULTS

Factors associated with an intention to recommend the HPV vaccine were perceived benefits, desiring more education regarding HPV and the HPV vaccine, and age of school health teachers.

PRACTICE IMPLICATIONS

Findings suggest a need for more education to promote a greater understanding of HPV and HPV vaccination among Korean school health teachers.

Knowledge, attitudes of human papillomavirus vaccine, and intention to obtain vaccine among Korean female undergraduate students

The purpose of this study was to examine knowledge about the human papillomavirus and attitudes toward human papillomavirus and human papillomavirus vaccination among Korean female undergraduate students. Moreover, this study sought to identify factors associated with intention to obtain the human papillomavirus vaccine. A cross-sectional study was conducted with 297 Korean female undergraduate students. Data were collected using a self-administered questionnaire. Collected data were analyzed with descriptive statistics, t-test or ANOVA, and stepwise multiple regression analysis. Only 37.8% of the participants were aware of human papillomavirus. The percentage of correct answers for knowledge about human papillomavirus was 40.6%. Factors associated with intention to obtain the human papillomavirus vaccine were: wanting more education about the vaccine, disease severity, knowledge of human papillomavirus, awareness of the human papillomavirus vaccine, human papillomavirus attributes, and susceptibility; these variables accounted 31.6% of the variance in scores for intention to obtain human papillomavirus vaccination. Findings from this study suggested a need for more active education to reduce the risk of human papillomavirus infection among female undergraduate students. Educational programs should be developed and evaluated, specifically focused on disease severity, susceptibility, awareness of human papillomavirus vaccine, and attributes of human papillomavirus.
