ABSTRACT Objective: To understand the health status of transitional resettlement sites and the needs of residents on health education, and to pro- vide basis for conducting health education after ear- thquakes and other public emergen- cies. Method: From May 31 to June 2, 2008 (19 to 21 days after the earthquake), field obser- vation, questionnaire survey, and structured interviews were conducted in five transitional resettlement sites. Information on health status, health service, health education, and residents’ needs on health education was col- lected. Results: 430 questionnaires were dis- tributed and 424 valid completed ones were returned. Food and water were adequately supplied. Clinics for health assistance were established and environment disinfecting was conducted regularly by public health profes- sionals. Health education was available to residents. The large proportion (98.6%, 97.9%, 88.7%, and 93.2% respectively) of the residents acknowledged that water supply, food supply, lavatories, and health service were adequate to fulfill basic needs. The overall disease in- cidence of surveyed residents was 44.8%, and diarrhea and fever with respiratory symptoms were the most common diseases. Among residents’ needs on disease prevention knowl- edge and skills, basic knowledge of infectious diseases was most desirable (49.8%), and safety knowledge of water uses was secon- darily most desirable (36.8%). The most fa- vored approach of obtaining knowledge was watching television. Conclusions: In the pe- riod of 20 days after the earthquake, Living security, health facilities, and health care ser- vice could satisfy residents’ basic needs. Post-disaster health education should con- centrate on basic knowledge and skills of communicable diseases and health- risky be- havior. Timely distributing disease prevention materials could be effective. Keywords: Earthquake; Disaster Areas; Health Status; Health Education; Needs; 1. INTRODUCTION On May 12, 2008, an earthquake with magnitude 8.0 hit Wenchuan, Sichuan Province. The quake caused thou- sands of deaths and injured, destroyed buildings and roads, and brought about huge financial loss. In the af- fected area, water and electricity supply were interrupted, and health care facilities and systems were enormously damaged, which resulted in the high risk for the outbreak and epidemic of intestinal communicable diseases, vec- tor-borne diseases, food-borne diseases, diseases of natural focus, and infectious diseases transmissible be- tween human and animals. Food and water safety, envi- ronmental health, health care service, and post-earthquake health education were the most impor- tant issues in disaster relief. To understand the health condition of transitional resettlement sites and residents’ needs on health education, Health Education Institute, Chinese Center for Disease Control and Prevention (China CDC) (Note:now named Chinese Center for Health Education/ Heath News Communication Center, Ministry of Health of China) conducted this study from May 31 to June 2, 19 to 21 days after the earthquake. 2. METHODS 2.1. Participant The resident in five transitional resettlement sites in Mianyang city, Sichuan Province were surveyed by the same questionnair, and they were from Beichuan county, one of the worst-hit areas. Four hundred and thirty questionnaires were distributed, and four hun- dred and twenty four valid questionnaires were re- ![]() Y. H. Li et al. / HEALTH 1 (2009) 298-303 SciRes Copyright © 2009 Openly accessible at http://www.scirp.org/journal/HEALTH/ 299 299 turned. Sixty participants (14.2%) were currently liv- ing in Huangtu transitional resettlement sites, seventy two (17.0%) in Anzhou driving school, one hundred and fourteen (25.9%) in Leigu, Beichuan, and sixty eight(16.0%) in Gaoxin. Participants were Beichuan County residents, 208 males and 216 females. The average age was 35.3±13.3,, the minimum age was 10 and the maximum age 84. Most of them (70.5%)had an elementary or middle school degree,and 78.3% of them were from Qiang minority race. 2.2 Sampling Methods Convenience sampling method was used to select five sites for observation and participants for survey. Age and gender were proportionally distribute. 2.3. Observation Administrators examined the heath condition, health care, and health education at transitional resettlement sites. Collected information included water and food supply, living health condition, environmental health (i.e., lavatories, and garbage collection and manage- ment), health care and drug supply, and the condition of health education. 2.4. Questionnaire Survey The questionnaire was self-designed and some contents were derived from environmental assessment question- naire developed by China CDC and WHO [1-3], includ- ing several dimensions: water and food supply, health condition, health care, incidence of diseases, and post- disaster needs. Participants were interviewed face-to- face by administrators. 2.5. Personal In-Depth Interview Participants were randomly selected from those who were recruited for questionnaire survey. Interviews fo- cused on post-disaster water and food supply, personal hygiene stuff, the interruption of cooking food, residents’ evaluation on health education materials, and the major difficulties they were facing. 2.6. Quality Control Survey Administrators Received Standardized Trainings They were guided and supported by local health depart- ments. Participants were informed of the intent and im- portance of the study. Leaders of each survey group su- pervised the information collection process and assessed every returned questionnaire 2.7. Statistical Analysis Epi data 3.0 was used to help data entry, and SPSS 13.0 was used to conduct statistical analysis. 3. RESULTS 3.1. Health Condition and Health Care It was indicated by observation and survey that there was sufficient drinking water and food supply in transi- tional sites. Lavatories were enough to serve temporary residents. Every transitional site had established tempo- rary health assistance and professionals to carry out en- vironmental disinfection. Health education in form of health materials, posts, lectures, and volunteer in-door health promotion was delivered. However, water for living was not adequate at several sites, and the types of medicine were limited, as shown in Table 1 and Table 2. 3.2. Diseases and Sought for Health Care Fifty eight participants (13.7%) ever had diseases or symptoms. Diarrhea (54.2%) and fever with respiratory symptoms (32.1%) were the most common health prob- lems. 3.3. Health Education Condition and Needs 3.3.1. Residents’ Health Knowledge, Belief and Practice Participants had some health-related knowledge and high level of awareness of drinking water safety and rabid. However, unhealthy behaviors occurred among residents, including drinking uncooked or unprocessed water, us- ing domestic water that had not been disinfected, and failing to discharge leftovers as shown in Table 3. 3.3.2. Health Education Needs In response to the question of the two most desirable things, 101 participants (23.8%) expressed that one of them should be health and disease prevention knowledge, while the majority of them supported that they should be the living necessities including water, food, and resi- dence. Thirteen participants thought that they did not need any assistance. In response the question of the two most desirable medical assistances, 188 participants (44.3%) supported that one of them should be diseases prevention knowledge and skills, while the majority of them wanted convenient health care service. Twenty six participants (6.1%) thought they did not need any health assistance. When it came to knowledge and skills of diseases prevention, basic information about communi- cable diseases was most favored, as shown in Table 4. 3.3.3. Where to Access the Knowledge and Skills of Disease Prevention Participants gained knowledge and skills mainly from the health education materials, including booklets, bro- chures, foldouts, and posts, and the programs broad casted by the speakers in transitional sites were the most popular strategy to deliver health education. The most favorable way is television and materials. ![]() K. C. Chou et al. / Natural Science 1 (2009) **-** SciRes Copyright © 2009 http://www.scirp.org/journal/HEALTH/ 300 3.4. Personal Interview Results One hundred and thirteen participants were inter- viewed. Twenty eight (24.8%) were currently living in Huangtu transitional resettlement sites, twenty five (22.1%) in Anzhou driving school, thirty six (31.9%) in Leigu, Beichuan, eighteen (15.9%) in Yong’an, and six (5.3%) in Gaoxin. There were 43 males (38.1%) and 70 females (61.9%). The average age was 40.3± 6.5, the minimum age was 10 and the maximum age was 71. Most of them (78.9%) were from 18 to 59 years old. The percentages of participants who experienced in- terruption of food, drinking water, domestic water, lava- tory, safe living places, health care, bathroom stuff, and food processing stuff were 45.0%, 45.5%, 44.4%, 46.2%, 53.3%, 48.1%, 53.8% and 83.0%, respectively.

The total period of the interruption was con- trolled to be within two days at every site. The existing difficulties include the singleness of food which caused digest problems and stomach upset of the elder and chil- dren, extreme density of living places where both tem- perature and humidity were at a high level, lacking of bathing stuff, children education, job interruption, the loss of household asset, and financial crisis. 86.9% of participants supported that post-earthquake health education was needed, and 41.6% of them thought that brochures and books were the best method of educa- tion since the content could contain a wide range of in- formation, be systematic, and be understandable. 78.2% of them had a positive evaluation toward the delivered or posted health education materials. 4. DISCUSSION The survey was conducted 19-21 days after the earth- quake. The results indicated that basic life necessities and health care facilities and service could fulfill resi- dents’ needs. Water and food supply were adequate, and there were sufficient lavatories and garbage recycling sites that were cleaned every day. Environmental disin- fection, mosquito, fly, and rat prevention had remarkable effects. Few flies and rats were observed by residents. However, many problems had been identified. There is the risk of food safety issue since food was from outside of the earthquake hit areas [4]. The mainly supplied food was packaged noodles and cookies, which could effec- tively prevent intestinal infectious diseases. However, more efforts should be made to enrich the types of food and provide appropriate food to the elder and children. It was fairly crowded in temporary tents where the tem- perature and humidity were high. Tents were not enough to ensure family as the small unit to be accommodated. Many health care sites only had emergency drugs like anti-bacteria and flu treatment drugs, but the drugs for chronic disease such as high blood pressure and diabetes were not enough to satisfy the needs. Moreover, the bathing stuff were so insufficient that residents could not shower every day. There were three kinds of lavatories available at each site: dry ones established after the tremor, remaining ones that survived from the tremor, and commercial mo- bile lavatories. The dry lavatories were the most appro- priate ones for environmental health. They were easy to build at a lower cost and could serve many people. The other two kinds of lavatory could not be cleaned easily since the water supply was interrupted, which could re- sult in the proliferation of flies and mosquitoes [5]. Ad- ditionally, commercial mobile lavatories were not easy to transport and their cost was high. Thus, it was sug- gested that dry lavatories should be established in time after earthquake. The most common health problems among residents were diarrhea, fever with respiratory symptoms, heat- stroke, cold, and dermatitis. The post-tsunami effects caused by stress sources such as lifestyle changes, the death of relative, and the loss of incomes could cause disorders of the immune system, make residents vulner- able to varieties of diseases. The density and humidity of the residence might be the cause for dermatitis. The environment changed dramatically after the earthquake. If residents lacked the knowledge and will- ingness of disease prevention, or there were not enough health facilities such as lavatories, personal hygiene stuff, or even if related facilities were available but residents did not have a healthy behavior pattern, communicable disease could break out easily. Thus, post-earthquake health education was highly important. According to the results of the survey, residents had some unhealthy be- haviors, like using non-disinfected river water as living water. Post-earthquake health education should follow the principles applying to outbreak public health emer- gencies, be delivered in time, and focus on those at high risk[6]. Booklets/brochures were the most favorable ma- terials since they can have a wide range of information, be systematic and understandable, be kept easily. Tele- vision was the most method favored by the residents. It was highly appropriate for those who receive less educa- tion. As residents were being relocated, televisions should be equipped. Furthermore, the speakers at each site should be fully used to implement health education. REFERENCES [1] Chinese Center for Disease Control and Prevention.
