Health Belief Model (HBM) 건강신념모형 1950년대 US Public Health Service의사회심리학자들에의해개발 특정건강검진프로그램 ( 결핵 ) 에사람들이참여하지않는이유를설명하기위한목적이시초 즉, 일회성의건강검진, 예방접종과같은행태를설명하고행동변화를유도하기위한모형으로출발 보다긴기간에걸쳐형성되거나행동변화가요구되는행태 ( 예 : 흡연등 ), 질병행태, 환자역할행태등으로적용범위가넓혀짐.

다음은김씨가금연이라는건강행태를선택하게된과정에대한사례이다. 건강신념모형 (Health Belief Model) 을구성하는각요소들에대응하는문장을찾아서쓰시오. 김씨는 44 세남자로중소회사인 실업영업과장이다. 김씨는고등학교 3 학 년이었던 25 년전부터담배를피워왔다. 물론김씨는담배를끊으면여러가지 로좋다는것을몇번의금연경험을통해알고있다. 담배에들어가는돈이나 주변이깨끗해지는것은둘째치고라도우선상습적인기침과가래가줄어들었 다. 담배를계속피우면폐암에걸리기쉽고폐암에걸리면기껏해야 1 년을버 티지못하고죽는다는사실도알고있기는하다. 하지만회사일을하다보면 스트레스도많고특히술자리를갖다보면담배가저절로따라오기때문에이 래저래끊지못하고있다. 영업과장으로서주변업체사람들과어울리기위해 서는담배가필수적이되어버린것이다. 그런데최근김씨는그회사의이사로 있던상사의상가에갔다온후, 최근담배를끊어야겠다는결심을굳히고실행 에옮기기로했다. 그상사는폐암으로 55 세의나이에세상을떠났는데, 김씨는 자신도그렇게될지모른다는생각을갖게된것이다.
다음은김씨가혈압약복용이라는행태를선택하게된과정에대한사례이다. 건강신념모형 (Health Belief Model) 을구성하는각요소들에대응하는문장을찾아서쓰시오. 김씨는 면에사는 56세농부로 5년전부터뒷골이땡기는증상을주소로읍내의원을방문하여고혈압진단을받았다. 그후 6개월간그의원에서주는혈압강하제로치료를받아오다임의로치료를중단하였다. 물론고혈압치료를하지않으면중풍같은합병증으로고생한다는말을의사에게서들었던기억은있지만 설마나에게그런일이있을까 하는생각에다가, 당장은증상이심하지도않고매일약을먹는것도귀찮아서약먹기를중단하고있다. 그러던중지난달, 같은마을에서양계장을하던이씨가중풍으로사지의왼쪽편을쓰지못하는신세로드러눕게되었다는소식을접한후, 김씨는마음을고쳐먹고읍내의원을찾아가기로다짐을하였다. 이씨또한고혈압을앓고있었는데그동안치료를해오지않았고, 김씨는자신도이씨처럼될지도모른다는생각을갖게된것이다.
Theory of Reasoned Action (TRA) and Theory of Planned Behavior (TPB) 합리적행동이론과계획된행동이론 TRA : 1967 년 Fishbein 에의해개발 (Fishbein 모형이라고도불림 ) 특정문제또는질병에대한태도 (attitude toward an object) 와그문제를해결하기위한행태에대한태도 (attitude toward a behavior with respect to that object) 를구분하였음. 예 : 유방암에대한태도 vs mammography 에대한태도 또한 belief, attitude, intention, behavior를구분하여정의하고측정하려하였음. TPB : Ajzen 등에의해 TPB 요소가추가 동기 (motivation, intention) 만으로는행태가일어나지않는다. 그동기 를실현할수있는능력 (ability) 이필요하다.

Social Cognitive Theory 사회인지이론 Social Learning Theory 라고도불림. 행태, 개인요인, 환경요인의 3가지요소가서로상호작용한다는생각에서출발 어느하나가다른하나의원인도, 결과도될수있다고생각 ( 상호결정론 reciprocal determinism) 개인요인 개인요인, 환경요인, 행태와의상호작용을통하여행태변화의가능성을높임. 행태변화를위한개인의지식과기술향상에초점을둠. 자기효능감 / 자아효능감 (self-efficacy, Bandura, 1995) 의중요성 : 개인이특정행동을하는데있어서느끼는자신감, 점증적과정의반복적성공을통하여강화

North Karelia Study in Finland The most prominent community-based experiments. (Ebrahim & Davey Smith, Eur Heart J 1998) Support of local community leaders and the general public. Involved mass media, workplaces, primary care, hospitals, schools and local communities. Provided training programes, mobilization of public support through local leaders, formation of new social organizations such as housewives groups, and targeting of grocery shops and the food industry.

Stanford Five-City Project, Northern California 6-year multifactor risk reduction education program that was coordinated, comprehensive, and community-wide. Had multiple target audiences and used multiple communication channels and settings (including newspapers, television and radio, mass-distributed print media, classes, contests, and correspondence courses) Change in diet, regular BP checks, reduced salt intake, reduced weight, increased exercise, and full adherence to antihypertensive medication regimens. On average, each adult in the two treatment cities was exposed to about 5 hours per year of Five-City Project educational messages.

The COMMIT Study Community Intervention Trial for Smoking Cessation Study One of the best planned randomized controlled trials at the community level in health promotion. (Ebrahim & Davey Smith, IJE 2001) Model of meticulous design, focused intervention, and careful analysis. (Susser, AJPH 1995) 11 community pairs, one community in each pair being randomized to receive smoking cessation activities. Public education through the media and communitywide events; health are providers; work-sites and other organizations; and cessation resources. Over 10 million dollars were spent on the activities.
Result of the COMMIT Study The COMMIT Research Group, Am J Public Health (1995)
Result of the COMMIT Study Quit rate among heavy smokers: 18.7% (11 intervention villages) vs 18.0% (11 comparison villages) [0.7% difference, 95% CI=-3%, +2%] The cost-effectiveness was around 50,000 per heavy smoker. Quit rate among light-moderate smokers: 30.6% vs. 27.5%
In recent years, we have seen a number of well-conducted, large-scale trials involving entire communities and enormous effort. These trials have tested the capacity of public health interventions to change various forms of behavior, most often to ward off risks of cardiovascular disease. Although a few had a degree of success, several have ended in disappointment. Generally, the size of effects has been meager in relation to the effort expended. That was the case with one of the first such trials, the ambitious Multiple Risk Factor Intervention Trial (MRFIT). It is also the case with some recent trials, for instance, the Stanford Five-City Project, the Minnesota Heart Health Program, and now the 26-worksite Take Heart trial and the 22-city COMMIT trials, which have smoking-related cancers as the ultimate target.

건강행태의역사적맥락
Lalonde Report Health Field Concept 건강의장모형
In the early seventies (what else is new!), two major concerns were growing in Canadian government circles: (1) the rising cost of health care, and (2) the fact that the health status of Canadians did not seem to improve proportionately with the rise in the cost of health services. After the significant improvements in health statistics following the introduction in Canada of public hospital and medical insurance in the fifties and sixties, the correlation between health expenditures and health improvement was becoming far less direct. When I was appointed Minister of Health and Welfare in 1972, it was clear that the issue had to be addressed. Lalonde M, Pan Am J Public Health (2002)
