BACKGROUND

Northern mountainous Vietnam is the main living area of the minority ethnic communities in Vietnam ethnic groups such as Tay, Nung, Thai, Muong, Dao, H'mong These are the areas with difficult transportation, low literacy levels by existing many outdated traditions, many potential risks of environmental pollution caused by man himself The percentage of households with clean water, sanitary latrines is very low, the main cause is being not good at environmental hygiene behaviors Dao people mainly live in the remote areas throughout Vietnam-China border from Lai Chau to Ha Giang province General characteristics of Dao people are underdeveloped economic, cultural, society, and poor environmental hygiene The question is what the status

of the Dao sanitary behaviors in some particularly difficult communes of Thai Nguyen province now is? What factors affect Dao’s sanitary behaviors? And whether the communication models of health and education can improve sanitary behaviors or not? To answer above

questions, we conducted a research on "The Status of Dao’s sanitary

behaviors in some particularly difficult communes in Thai Nguyen and testing intervention models" with the objectives:

1 Assess the situation of the Dao’s sanitary behaviors in some extremely difficult communes in Thai Nguyen 2011

2 Describe some factors related to Dao’s sanitary behaviors in some extremely difficult communes in Thai Nguyen province

3 Assess the result of the testing the communication models in changing sanitary behaviors for Dao people in Vu Chan commune, Vo Nhai district, Thai Nguyen province

THE NEW CONTRIBUTIONS OF THE THESIS

1 The result of the thesis has described the overall big picture of the current status of the Dao’s sanitary behavior living in particularly difficult communes in Thai Nguyen province

2 This is the first intervention study in the Dao community which has provided the evidence, factors related to environmental hygiene behaviors of the Dao living in particularly difficult communes in Thai Nguyen province

3 The Model "Communication in changing sanitary behaviors for the

Dao in Vu Chan commune" has been mobilizing the resources of the

community, the prestigious Dao people participating in the programe to improve the sanitary behavior for them The research model is integrated into The primary Health care Committee of the commune, functions and duties assigned specificly and clearly with the pivotal role which is the Fatherland Front This is the basis for the model to develop sustainably and feasibility

Chapter 1 OVERVIEW 1.1 Current status of sanitary behaviors of the Dao in Vietnam

According to WHO "Human behavior is a complex set of actions, but these actions are influenced by many inside and outside, subjective and objective factors."

Behaviors are influenced by internal factors such as knowledge, attitudes, beliefs, values, personal experience of practice, behavior and external factors such as legislation, regulations, family, friends, the reputed people The activities have repeated several times, gradually become a lifestyle Lifestyle is also influenced by anthropology, culture, society, psychological factors Lifestyle is a set of behaviors, creating a human life, including many specific issues such as practice personal hygiene and the use of sanitary facilities, living habits of individuals, families and communities, customs Every behavior is a specific expression outside and affected by many elements that are knowledge, attitude, practice (KAP) and the belief of people in a certain work or situation

1.1.1 Behavior in using clean water of Dao people

Results of the survey of Preventive Medicine and Environment Department in 2010, on the environmental hygiene conditions of some ethnic minorities in Vietnam showed that the Dao mainly used headwater streams and wells, very few people use tap water, rain water and wells: 57.6% of households using water from headwater streams, 18.3% of households using water from wells; few households using other water sources (0.7% of households using well water); not any households use tap water and rain water However, 2.1% of households still use water from rivers, lakes, and 21.4% are using other sources of water which is not clean Nearly half of Dao households in the survey (49.7%) admitted drinking (unboiled) water

1.1.2 Behavior in using Latrine of the Dao

Some studies of Hoan, D.K (2003), Hoc, N.D (2003) showed that the proportion of the Dao households who have latrines accounted for 50.4% of the surveyed households, but the proportion of households with suitable latrines were very low, only 5.8% Of which there were only 5.1% of two separated compartment latrines, 0.3% of septic latrines, 0.3% of absorbed flush toilets The Dao households who have no latrines defecate to the gardens and forests (85.5%), use the others’ households

(4.5%) or to the barn (10%) Reasons for not building latrine of the Dao

is like the other minorities, mostly "no money" (76.9%); "no need" (21.3%) and "do not like" (1.2%)

1.2 The affects of habits on the sanitation health of the Dao

According to the census of population and houses in 2009, the Dao

in Vietnam has a population of 751,067 people, accounting for 0.87% of the whole national population, ranking 9th in ethnic groups, ranking 2nd

in countries where the Dao live, residing in 61 out of 63 provinces and cities The Dao (other names: Man, Dong, Trai, Diu Mien, Kim Mien,

Lu Gang, Lan Ten, Dai Ban, Tieu Ban, Coc Ngang, Coc Mun, Son Dau etc) usually live in the valleys, low hills, surrounding foothills or along streams, where has headwater They live in clusters, small separate hamlets and people gathered around the theocratic, with particular characteristics on the traditions and the most evidence is on their clothes such as Red Dao, Dao Quan Chet, Dao Thanh Y, Dao Ao Dai, Dao Quan Trang Although they have many different groups, their language is united to connect the close relationship between the Dao communities with each other Dao groups have similarities in customs, habits, economic patterns and beliefs

1.3 Some models of communication in changing sanitary behaviors

* Model of community health workers in Zimbabwe: Community

health workers selected are respected, literated and trained in the community Health care models demonstrate the role of the prestigious leader in the community

* Approach "Total Sanitation owned by the community - CLTS - Community led Total Sanitation": CLTS approach is to achieve and

maintain the status that does not defecate indiscriminately through guiding community to analysis hygiene, toileting habits and its aftermath, from which putting out collective action not to defecate indiscriminately into the environment (UNICEF -2009)

* Approach "Marketing toilet - SanMark": access to

market-oriented in order to take advantages of non-governmental organizations, the private sector, and state management agencies to assess and improve sanitation for households in poor rural areas in a sustainable way The Capital course of the program will not be used to sponsor on purchasing materials and building latrines, but to focus on the implementation of activities in order to develop Sanitary market (IDE - USA)

* Mobilizing model community into communication - health education some contents of primary health care to the people of Long Tan - Dong Hy – Thai Nguyen: Mobilizing the community to participate

in health education programme implementating the primary health care under the direction of the steering sanitation committee of the commune (Dam.K.H -2010)

* Approach "Mobilizing communication communities to improve sanitation behavior in the remote and isolated areas of Cay Thi commune, Dong Hy District, Thai Nguyen Province": using educational

methods and communication to change the people behavior from which they make the investment in building clean water project and sanitation

of the family, no funding for latrines (Hoan,D.K, 2007)

Based on the formula, n = 99, rounded up to 100 samples/commune

* Sampling Techniques: In the households interviewed, 100

households in each commune were randomly selected to test soil sampling in many diferent positions: in the house, in the yard, on the way to the toilet and around the toilet Sample Ascaris eggs in soil were conducted in two communes, Vu Chan (intervention) and Lien Minhh (control) at 2 diferent periods, before and after intervention

2.4.2.4 The sample size for qualitative research:

- Discussion: Each commune conducts two discussions at 02 periods, before and after intervention with the leaders of community groups and the representing people of Dao community

- Further interview: 5 prestigious people in the Dao villages

2.4.3 Content intervention

2.4.3.1 Construction intervention model Methods

Step 1: Define the content to be mobilized to solve the problems of sanitation behavior

Step 2: Study the problem and collect the data

Step 3: Develop general and specific objectives to mobilize communities to improve priority sanitation behavior

Step 4: Determine the solution and specific actions to carryout the models

Step 5: Develop monitoring and evaluating tools to measure the results of operations of research models

2.4.4 Research index and evaluation standards

2.4.4.1 Index group to assess the status of the Dao sanitation behavior

- Sanitation actions including: act of using clean water, act of using sanitary latrines, act of using sanitary breeding facilities and behavior of disposing waste litter These behaviors are evaluated based on "The monitoring indicators and evaluation clean Water and environmental Sanitation in Rural area" issued together with Decision No 2570, dated 10.22.2012 of the Minister of Agriculture and Rural Development

- General behavior of sanitation of the Dao is assessed through interview, observation and quantified by scoring in principle of getting 2 points for correct answer, 1 point for unfully correct answer, no point for unknown or incorrect answer Based on cutting 50% of total segment, the score divides sanitation behavior into 2 levels: pass level: ≥ 50% of the total score, no pass level: <50% of the total points

2.4.4.2 Index group of the factors related to the behavior of the Dao sanitation

- Education: Classification at the highest level

- Poor households: the average income from as 400,000/person/month (from 4.800.000VND/person /year) or less

- Households with media (ECD) are households which have still working radios, televisions, presses…

- Sanitation knowledge: Pass (≥50%), no pass (<50%) score

- Sanitation attitude: Pass (≥ 50%), no pass (<50%) score

2.4.4.3 Index group evaluation the results of communication and sanitation model

- Results of the model: The numbers of organizations are mobilized

to participate in the programme, the communication sessions, the numbers of people on the communication, the supervision sessions, training sessions

- The change about knowledge, attitude and behavior of the Dao sanitation before and after intervention

- The change about Ascaris eggs polluted situation in the soil in the Dao households Ascaris eggs/kg of earth: <100 is cleared soil, Ascaris eggs/kg of earth: > 100 is dirt soil

- Evaluation results by effective indicators and interventions

2.5 Methods of collecting information

- Direct interviews the heads of households according to the questionnaires

- Investigators observe the sanitation conditions in the households and assess by sanitation checklist

- Test of Ascaris eggs in soil: Ngu.D.V’s improved method In each sample, 10g soil is tested to find, and count the number of Ascaris eggs

in soil samples (3 eggs = 1+)

- Further interviews: the prestigious people of the Dao as the oldest

or the head of the village

- Group Discussion: with community leaders, the groups of citizens representating for the Dao communities

- Data is processed on SPSS 18.0 using descriptive statistical methods and analysis The relationship is measured by the prevalence

ratio index, the statistical significance is p <0.05 of testing x

- Ethics in research: an experimental study in the community is accepted by the community Research is assessed by the Science Council

of Thai Nguyen Medical and Pharmacy University before conducting Participants volunteer, they may refuse to participate at any time
