Changes in skin reactivity and associated factors in patients sensitized to house dust mites after 1 year of allergen-specific immunotherapy.

BACKGROUND: Allergen-specific immunotherapy (SIT) can significantly improve symptoms and reduce the need for symptomatic medication. OBJECTIVE: The aim of this study was to investigate changes in skin reactivity to house dust mites (HDMs) as an immunologic response and associated factors after 1 year of immunotherapy. METHODS: A total of 80 patients with allergic airway diseases who received subcutaneous SIT with HDMs from 2009 to 2014 were evaluated. The investigated parameters were basic demographic characteristics, skin reactivity and specific IgE for HDM, serum total IgE level, blood eosinophil counts, and medication score. RESULTS: The mean levels of skin reactivity to HDMs, blood eosinophil counts, and medication scores after 1 year were significantly reduced from baseline. In univariate comparison of the changes in skin reactivity to HDMs, age ≤30 years, HDMs only as target of immunotherapy, and high initial skin reactivity (≥2) to HDMs were significantly associated with the reduction in skin test reactivity. In multivariate analysis, high initial skin reactivity and HDMs only as target allergens were significantly associated with changes in skin reactivity to HDMs. In the receiver operating characteristic curve of the initial mean skin reactivity to HDMs for more than 50% reduction, the optimal cutoff value was 2.14. CONCLUSION: This study showed significant reductions in allergen skin reactivity to HDMs after 1 year of immunotherapy in patients sensitized to HDMs. The extent of initial allergen skin reactivity and only HDMs as target allergen were important predictive factors for changes in skin reactivity.

Assessment of village health worker training program in Tuguegarao, Philippine.

OBJECTIVES: This study was performed to evaluate the effectiveness of 'village health worker training program' which aimed to build community participatory health promotion capacity of community leaders in villages of low developed country and to develop methods for further development of the program. METHODS: The intervention group were 134 community leaders from 25 barangays (village). Control group were 149 form 4 barangays. Intervention group participated 3-day training program. Questionnaire was developed based on 'Health Promotion Capacity Checklist' which assessed capacity in 4 feathers; 'knowledge', 'skill', 'commitment', and 'resource'. Each feather was assessed in 4 point rating scale. Capacity scores between intervention group and control group were examined to identify changes between the pre- and post-intervention periods. A qualitative evaluation of the program was conducted to assess the appropriateness of the program. The program was conducted in Tuguegarao city, Philippine in January, 2009. RESULTS: The result showed significant increases in the total health promotion capacity and each feather of health promotion capacities between pre and post assessment of intervention group. But there was no significant change in that of control group. Participants marked high level of satisfaction for preparedness, selection of main subjects and education method. Qualitative evaluation revealed that training program facilitated community participatory health promotion capacity of participants. CONCLUSIONS: This study suggested that the Village health worker training program is effective for building health promotion capacity of community leaders and it can be a main method for helping low developed countries with further development.

Assessment of community capacity building ability of health promotion workers in public health centers.

OBJECTIVES: This study was performed to assess the community capacity building ability of health promotion workers of public health centers and to identify influential factors to the ability. METHODS: The subjects were 43 public officers from 16 public health centers in Busan Metropolitan City. Questionnaire was developed based on 'Community Capacity Building Tool' of Public Health Agency of Canada which consists of 9 feathers. Each feather of capacity was assessed in 4 point rating scale. Univariate analysis by characteristics of subjects and multivariate analysis by multiple regression was done. RESULTS: The mean score of the 9 features were 2.35. Among the 9 feathers, 'Obtaining resources' scored 3.0 point which was the highest but 'Community structure' scored 2.1 which was the lowest. The mean score of the feathers was relatively lower than that of Canadian data. The significant influential factors affecting community capacity building ability were 'Service length', 'Heath promotion skill level', 'Existence of an executive department' and 'Cooperative partnership for health promotion'. According to the result of multiple linear regression, the 'Existence of an executive department' had significant influence. CONCLUSIONS: Community capacity building ability of subjects showed relatively lower scores in general. Building and activating an executive department and cooperative partnerships for health promotion may be helpful to achieve community capacity building ability.

[Introduction of health impact assessment and healthy cities as a tool for tackling health inequality].

In order to reduce the health inequalities within a society changes need to be made in broad health determinants and their distribution in the population. It has been expected that the Health impact assessment(HIA) and Healthy Cities can provide opportunities and useful means for changing social policy and environment related with the broad health determinants in developed countries. HIA is any combination of procedures or methods by which a proposed 4P(policy, plan, program, project) may be judged as to the effects it may have on the health of a population. Healthy city is one that is continually creating and improving those physical and social environments and expanding those community resources which enable people to mutually support each other in performing all the functions of life and in developing to their maximum potential. In Korea, social and academic interest regarding the HIA and Healthy Cities has been growing recently but the need of HIA and Healthy Cities in the perspective of reducing health inequality was not introduced adequately. So we reviewed the basic concepts and methods of the HIA and Healthy Cities, and its possible contribution to reducing health inequalities. We concluded that though the concepts and methods of the HIA and Healthy Cities are relatively new and still in need of improvement, they will be useful in approaching the issue of health inequality in Korea.
